過去に音楽CDのバックアップをbinとcue拡張子のイメージファイルでしていた吾輩

当時はバックアップ作成時にWindowsアプリを使用したと思うのですが
はっきり覚えていない

さて今回はマックにて音楽CDのバックアップをしたいと考えて調べてみるとBurnにてiso+isoinfoのイメージファイルで出来ることを前日に紹介しました

Macのディスクユーティリティだと音楽CDのdiscイメージを作成出来ない

所が実際にこのBurnのisoとisoinfo拡張子のファイルですと
Burnのみでバックアップと書き込みが出来るので使用するには良いのだけど
書き込み前には中の確認ができす実際にCDに書き込んで開いてみないと解らない

これでは使い勝手が悪いので書き込み前に
このイメージファイルをマウントして中を開いて確認出来るソフトを探してみると

DAEMON Tools for Macが在りました

所がDAEMON Tools for Macではisoとisoinfoのイメージファイルはマウントできません

それでも音楽CDでbinとcueのイメージファイルではマウントできるので
結局最初にしていたbin+cueのイメージファイルでバックアップを取る方法が
やっぱり一番使い勝手が良いということになりました

だだ最初に使用したDAEMON Tools for Macではインストール時に
試用を選んでしまい20日間の試用期間終了後にどうなるのか解りませんでした

所が使用中にアップデートが在ることが在り
アップデートを実行するとライセンスの選択画面が表示されまして
ここで無料ライセンスを選びました
DAEMON Tools for Mac ライセンス

これで仮想マウントのみ可能となりました
他の機能が必要な方は必要な機能だけを追加購入することや試用もできるようです
無料ライセンス

これで仮想マウントは可能となりましたが
Macでbin+cueのイメージファイルを作成(書き出す)ソフトと
書き込みが出来るソフトが必要となりました

もちろん先に書いたDAEMON Tools for Macの機能で作成(書き出し)と書き込み機能のみを
有料で購入しても良いでしょう
ちなみに作成とイメージ作成を1PCで使用するライセンス料は$14.00(¥1,505)です
DAEMON Tools for Mac ライセンス料


でも自分の場合そんなに音楽CDを今後使用する機会もないと思うので
フリーで探してみます

・bin+cueのイメージ作成(書き出し)に対応しているソフトにはAnyToISO Liteを使用しました

このAnyToISO Liteバージョンは完全に無料ですが
そのかわり通常のCDサイズ(870 MB)以下のでのみ機能する制約が在ります

実際にbin+cueのイメージ作成(書き出し)の動作確認をしてみましたが
問題無く使用できました
AnyToISO Lite



・つぎにbin+cueのイメージの書き込みに対応しているソフトにはSimplyBurnsを使用しました
 *追記:Burnでもbin+cueのイメージの書き込みに対応していました

SimplyBurns メイン画面

動作が安定しているrev428は2011年にリリースされたもので
古いですが現在は64ビットバージョンを開発中でαバージョンの3が公開中です

実際に両方使用してみましたが64ビットバージョンでは
bin+cueのイメージの書き込みでサイズが0B表示で正常に動作しませんでした

合計サイズが0Bの表示
SimplyBurns 64ビットバージョン

rev428では合計サイズが表示されその後の操作も問題無く書き込みができましたし
その後普通の音楽CDとして使用できました

音楽CDをレンタルなどで借りてきてiTunesに読み込んだ後に
後日読み込みフォーマットを変更して再度読み込んだり
なにかの事故でファイルが無くなった場合などの保険で
CDのバックアップが欲しい所です

そこでMacのディスクユーティリティを使用して
音楽CDのdiscイメージを作成しても
マウントしようとしても「マウントできるファイルシステムがありません」と
エラー表示になりバックアップは出来ません

それではどうしたらよいか

一つの方法として
サードパーティーツールのBurnを使用します

今現在の最新バージョンは2.7.7で
今回もこちらをダウンロードして使用しました

zipファイルをダウンロードして解凍すると
Burnフォルダが作成されて中を開くとBurn.appが在りますので
アプリを立ち上げます

そしてまずコピータブを選びます
Burn 初期コピー画面


画面案内通りここではオリジナルCDをドラックしたり開くやスキャンから選ぶと
以下のような表示に変わります
Burn 選択


CDタイトルが表示されますがここでは種類が「RAW*」になっています
ここで保存を選んでも書き込みしても*問題無いと思うのですが
(*実際にこの2つのファイルを重複確認ソフトで比較確認すると別のファイルとなりました)
これが気になる方はここでもう一度スキャンタブを選んで
表示されたスキャンリストから再度選んだCDを選び直します

すると種類が「オーディオCD」に変更されます


スキャンリスト
Burn スキャン


種類が「オーディオCD」表示になります
  Burn コピー

ここで保存を選んで保存するとisoファイルで
isoとisoinfo拡張子の2つのディスクイメージファイルが作成されます


書き出し中の画面
Burn 書き出し中


書き出された2つのファイル
isoとisoinfo


この作成した2つのファイル中isoの拡張子ファイルのみでは
finderでマウント不可で出来ませんし
burnでも正しく認識されず
「未知のディスクイメージ ディスクのフォーマットを決定できません」との案内が出ます

ここではiso拡張子ファイルでは無くisoinfo拡張子ファイルを
burnに読み込ませると種類が「Audio-CD image」として認識され
書き込むことも可能になります
Burn issoinfo


ここでは試しでCD-RWでディスク作成した音楽CDでも問題無く
iTunesでも読み込めました

9年前のMacBook Proを使い
たまにWindows10も使用していますが
そろそろ中古でも良いので予備で欲しいと思って
イオシスの中古品を購入候補にしていたのですが
タイミング良くドン・キホーテにて
第四弾企画商品が先月から発売されていたので
保証外の中古のバッテリーよりも新品と言うことで売切れ覚悟で今日はほぼ初ドン・キホーテへ


店に行くとPOPにチラシで今日まで一人一個の数量限定で発売されていたみたいです
ドン・キホーテ PC&タブレット


でもこれは元々期間限定の商品ではないし期間限定の割引価格でも無いし
通常の販売だと思うのですがこう書いて購買意欲を誘う為でしょうかね

空箱は山積みされていたけど実物が無く売切れなのか
もしくは盗難防止でこの空箱をレジに持っていけば良いのかも判らない

しばらく待って店員さんに確認したかったけどまったく現れず

結局一度諦めて初ドンキなので周囲をウロウロして時間を潰してから戻って
やっと捕まえた店員さんは新人さんで
在庫の確認を聞いているのにその行動がまったく理解できない意味不明でして
結局無線連絡で担当者を呼びだして
担当者が来てからやっと在庫が在ることが解りました

店の奥へ商品を取りに行き商品が出て来てからはそのまま新人教育へ

3年と5年から選べる長期保証のセールスが始まり
3年が1000円と言う事でほとんどの方がこれを選ばれるとの説明を受けて
ドン・キホーテの第一弾の完成度が全くだめだったので
保険と思いそのまま追加購入してそのまま新人を連れてレジへ

運が良いのかこれが普通の対応なのか
行列が出来たレジには並ばずに新人さんにレジ操作の教育をしつつの支払いも完了!

無事に手に入れました
ドン・キホーテ PC&タブレット

最初の予定では中古のタブレットで9,980円の予定より
保証をつけて合計で22464円と高く付きましたが
全てが新品になりメモリーもROMが64GBと
これまでのドン・キホーテ企画品の倍になっていて

基本的に購入候補だった中古品とスペックとほぼ同じです

しばらくこれで遊べそうです
後日使用感等アップしたいと思っています

Elitech RC-5 USB 温度データーロガーに初期不良が無かった事を確認後
次に初期設定をダウンロードしたアプリを使用して設定します

吾輩は基本Macの使用なのでマック版のアプリの使用を紹介します

まずクイックスタートガイドに書かれているURLから
http://www.elitechlog.com/softwares/
Elitechlog Mac V2.3をダウンロードして使用します
ダウンロードのページにはElitechlog Mac V1.2と表記されていますが
ダウンロードしてみるとアプリはElitechlog Mac V2.3でした


吾輩の環境で V2.3を使用するとごくごく一部が中国語の表示がありました
Historical data項目、System Settings項目、Settings項目、Overview項目の各一部が中国語表記でした

Historical data項目の例
中国語

少し気になるので以下の中国ページより事前にV1.2.1をダウンロードしていたので
こちらを使用しています
http://www.e-elitech.com/index.php?v=software_show&id=296

Macの場合このElitechlog Macアプリ使用で
すべての種類の温度データロガーと互換性があるので悩む必要がありません

ダウンロードしたファイルから
開いたフォルダーからElitechLog.appをアプリケーションフォルダにコピーします

次に今回購入したRC-5に対応したドライバーをインストールします
driverフォルダー内にあるRC-5/RC-6/GSP-6フォルダーを開くと
インストールパッケージ(CH34x_Install_V1.5.pkg)が在るので
それをクリックして案内に従ってインストールします

はじめに
CH34x_Install_V1.5.pkg

インストール先
CH34x_Install_V1.5.pkg

インストールの種類
CH34x_Install_V1.5.pkg

インストール確認
CH34x_Install_V1.5.pkg

インストール認証
CH34x_Install_V1.5.pkg

インストール中画面
CH34x_Install_V1.5.pkg

これでインストールが終了後
コンピュータを一度再起動しその後
インストールしたElitechLogアプリを実行してRC-5の設定を行う必要があります

これをしないと内蔵の時計が初期状態の時間が合っていない状態で記録されますから
インストールしたElitechLogアプリを起動すると
ElitechLog For Mac V1.2.1の画面のOverviewが開きますので
その中のDevise info項目の日付が2012年2月1日の表示になっているので
まず日時を設定しなければならないことが解ります
ElitechLog For Mac V1.2.1

次に基本Settingsのタブを選んで変更するのですが
ここで日付と時間の表示フォーマットを変更したい場合は
先にSystem Settingsアイコンをクリックして希望のフォーマットに変更して保存します
ElitechLog For Mac V1.2.1

次にSettings画面から時間の設定です

Logger Clock(端末時間)
ここで手間取ったのが日時変更しようとLoggerClock欄を選ぼうとしても選べないのです
ElitechLog For Mac V1.2.1

でも分かれば簡単でただ単にここで一番下に在るSaveアイコンをクリックすると
RC-5に設定が書き込まれので
これで自動的にPCの現在時間がRC-5に上書きされます
つまりPCの時間が狂っていればRC-5も同じ狂った時間になります
ElitechLog For Mac V1.2.1


Settings画面からRC-5で他に変更が可能なのは
Logger ID、trip desc.、Log Interval、Start Delay(HH:MM)、Alarm Tone Settings(Alarm Tone Interval)、Prompt Tone Settings、Stop by Button-press、Temp Unit、Upper Limit(Temp)、Lower Limit(Temp)、Calibration(T)です

Logger ID(端末No.)
これは同じLoggerを複数使用する場合に使用するメモ的な設定です

trip desc(端末説明情報)
こちらも同様に説明文などを記入するメモ欄です

Log Interval(記録間隔)
温度を測定し、記録する間隔を設定します
10秒から11時間59分50秒まで10秒単位で設定できます

Start Delay(HH:MM)(記録遅延)
本体のスタートボタンを押してから
記録を開始するまでの時間を30分後から30分間隔で6時間後までで設定します

Alarm Tone Settings(アラーム音の回数設定)
アラーム音は、「Disable(無効)「0」」、「3」、「10」から選択します

Alarm Tone Interval(アラーム音の間隔設定)
アラーム音を設定した場合、アラーム音の間隔を「1M」「5M」「10M」「20M」「30M」から選びます

Prompt Tone Settings(入力音設定)
本体のボタンを押した時の確認音の設定で
Disable(無効)と「Enable(有効)」がありますが
RC-5では「Enable(有効)」設定しても音が出ません

Stop by Button-press(ボタンによる停止)
本体の一時停止ボタンを押した場合
ログの記録を一時停止するか無効にするかを設定します

Temp Unit(温度の単位)
表示する温度の単位をセ氏°Cと華氏°Fから設定します

Upper Limit(Temp)(温度の測定上限)
測定する温度の上限を指定します
RC-5の上限は70度なので通常70の設定で良いと思います

Lower Limit(Temp)(温度の測定下限)
測定する温度の下限を指定します
RC-5の下限は-30度なので通常-30の設定で良いと思います

Calibration(T)(温度の補正)
温度のズレの調整を行います
例えば、手持ちの基準とする温度計と比較して
1℃低めに測定される場合は「1」を入力します



最後に設定が終了したら一番下に在るSaveアイコンをクリックして
RC-5に書き込んだら設定が完了します

後は温度の記録を開始したい時にスタートボタンを長押しすると
液晶画面に”▶”が表示されてログの記録が開始されます
RC-5


最後にこの設定を書き込む毎にRC-5のこれまでのログは全て消去されますので
必要に応じでログを記録してから設定を変更してください

RC-5に設定を書き込んだ場合これまでのデータは自動的にデータベースに保存されますので
いつでもデータを見ることができますし
設定を変更していない場合でも
アプリのSave Dataを選べばこれまで記録されているDataを
手動でPCに読み込み保存する事もできます

またパソコン本体のUSB端子にこのRC-5を直接差し込むと
PC本体の熱を伝導して温度が狂いますので気になる方は延長ケーブルを用意する等で対応してください

次は実際に記録したログの表示を確認したいと思います

外箱には中国製でアメリカの社名と住所が入っていましたので
アメリカで販売している商品でした

中国で販売している商品でなくて一安心です

先日、色々と温度を計測する機会が多いので
温度を記録するアイテムを1,600円にてアマゾンにて購入しました

一応バングッドでも購入できたのですが1,702円でした
バングッドではたまにコピー品やB級品が混ざっていて
この商品説明の写真からも正規品は商品の裏にシリアル番号のシールが貼られているのですが
このページの商品にはそのシールが貼られていなくB級品の可能性がある疑わしいものでした

また商品パッケージの写真にも中国語が印刷されているし
商品が上下逆に収まっているのでまさしく中国で販売されている商品で
今回はバングッドでの購入は無しです
RC-5


とりあえず製造元はすべて中国ですが
販売は中国と、米国、英国の3つの代理店の商品が混在しています
B級品の情報はアマゾンのレビューから得た情報です

また代理店等このRC-5を購入するまでの情報と
購入後の操作方法等の情報を以下のページを参考にしています
RC-5、RC-5+、RC-4、RC-4HCは定期的に自動で温度を測り続けるデータロガー からです

アマゾンでの販売価格が一番安く
その代わりにAmazonマーケットプレイスの出品者からの購入で
中国から送られて来る商品でした

急いで欲しい物でも無かったのでこれで問題は無し

さらに手持ちの割引ポイントを一番利用できて安く購入できる物でも
たまたまアマゾンのギフト券の手持ちがあったのでギフト券を使用して
920円の追い銭での購入でした

本日届いた商品ですが
発送情報では配送業者がChina Postだったのでてっきり郵便局で届くと思ったのですが
なぜかクロネコ便でした

更にアマゾンの箱で届いて
伝票の送り元は千葉県市川市に在るアマゾンからでした
アマゾン


そして中には謎の伝票
謎の伝票


想像するに今回購入したお店では国内発送と中国発送の商品を
価格に違いをつけて同時に販売していました
国内発送品は今回届いた千葉からのアマゾンから届くのですが
中国からの発送というのは建前で
意図的に発送を遅らせて取引業者返品という方法で
アマゾンの在庫品から自分に商品を送り経費を抑えたのでは?と勝手に考えます

中を開くと驚きの梱包です
緩衝材は入っていますが全く意味が無く
運搬中は中で商品が底で転がっていた状態でした
箱の中

最初は商品レビューを書くつもりでしたが
結果はこのような形になってしまいました

昨日注文しましたAnker SoundCore mini が届きました
Anker SoundCore mini レビュー

箱を開けるとこのような感じで商品が入っているのですが
ここで注意しなければならないのが充電ケーブル
本体を固定して収めている紙のボックスの中に収まっています

写真では本体の上部にちらっと見えている黒い物が充電ケーブルです
Anker SoundCore mini レビュー

中に入っているのはこの4点
本体、充電ケーブル、取扱説明書、メッセージカード
Anker SoundCore mini レビュー

底面にはゴムで滑り止め処理されているので
車で移動中にも振動で底面からの音が発生したり
スピーカーが滑る事は基本無いと思います
まぁ急なハンドル操作などをしたら滑る前に転がると思います
Anker SoundCore mini レビュー

まず最初にスイッチを入れるとペアリングモードとなり
電源が入った事を知られるサウンドが鳴り
再生や音量を操作するボタン下にある
状態を知らせるLEDが青色に点滅します
Anker SoundCore mini レビュー

スマホ側のBluetoothをONにしてペアリング設定すると
ペアリングされたサウンドが鳴り機器との接続済みを表す
LEDが青点滅から靑点灯に変わります

他のAUX入力やmicroSDカードやFMラジオのモードの時は
このLEDは白点灯になります


スマホ側に電池の残量も表示されて
届いた直後の残量は半分ほどでした
Battery残量表示

試しに音楽を再生してみると
音量設定が大きい状態になっていたので
想像以上に大きな音がして慌てて音量を小さくしました

自分のスマホの場合、音量は15段階30段階の調整なのですが
通常真ん中の7辺りで良さそうです

音質も安っぽい音では無く良い音で全く不満はありません

本体側の音量調整のボタンは
長押しで次の曲、前の曲への操作を兼ねていますので
音量を大きく変更したくても長押しすると曲のskip操作になるので
音量を連続で変更することが出来ません

ボタン1押しでの操作になります
本体側は15ステップで音量操作が出来て
最大音量の状態で更にプラスボタンを押すと
確認音がしてこれが最大音量という事を知らせてくれますが
最小音量側は音が聞こえなくなるのを自分で確認できるので知らせてくれません

なので基本は再生側で音量操作する事になり
この操作は本体のみでFMやmicroSDカードの再生で使用する事になると思います

電源にはオートパワーオフ機能があり
無音の再生していない状態が約10分続くと電源が切れます

一度オートパワーオフしてしまうと
電源操作をして再度接続しないといけません

再生モードの切替はボタン操作になりますが
基本何をスピーカーに接続されたかを認識して
接続したモードに自動で切り替わりますので
このボタンはFMラジオとの切り替えや
microSDカードやAUX接続等の複数の接続を
すでにしている場合に操作するボタンになります

本体の充電状態を表示する白色LEDは
充電の必要が無い場合は点灯せず
充電が必要な時のみ点滅し
充電中は点灯しています
Anker SoundCore mini レビュー

どちらにしても
どの商品でも最初は操作に手間取りますが
操作に慣れれば簡単です

この商品もすぐに操作になれましたし
良い仕事をしていると思います

microSDカードに就寝時の音楽を入れて常時差し込んで
本体のみで生成できるようにしておきたいです

最後に購入直後の不満といえば
操作パネルや表示パネル等の位置が
前面に再生/停止、+、−の操作ボタンと状態を示す青LEDがあり
裏面に他の電源ボタンや接続スロット、内蔵マイク等の全てがありますが
これをなぜ前面と後面に分けたのかが理解できません

操作する側としては裏面にあっても見えないので
見える表面にすべてを集めた方が
見て状態が解るし操作もしやすいと思うのです

まぁスピーカー自体が小さいので
無線状態での操作は本体を手に持ってすると思うで
そんなに問題ないのかな〜と
ちょっと考えすぎですかね

先日使用しているスマホのスピーカーを外し音が出ない仕様にしたのですが
やはりベットで寝ながら動画を見る時は不便です

そこでBluetooth対応スピーカーの購入を考えて
ネットで調べた結果
ノーブランドの中国製の商品も目に止まりましたが
レビューではノーブランド品だとやはり当たり外れが在るので
結局モバイルバッテリーを使用していて
吾輩の中では評価の良いAnkerのBluetooth対応スピーカーが目に止まりました

もちろんAnkerの商品にも何種類か商品があって
最後の候補に、SoundCore miniとSoundCore mini2、
Soundcore Icon Mini、Soundcore Ace A0が残りました

大きな特徴は以下の通りです

Soundcore Ace A0
モノラル2W、ズボンのポケットにもキーホルダー感覚で取り付ける事が出来ますが
小さい分連続再生時間が4時間となり
小さいので他の操作機能も限られていてハンズフリー通話機能は無し

SoundCore mini
モノラル5W、連続再生時間が15時間、ハンズフリー通話機能、
micro SDカード使用で単独再生可能とFMラジオ受信機能
ノイズキャンセル機能付きマイク内蔵


SoundCore mini 2
SoundCore miniの改良と機能が変更された新製品
モノラル5Wから6Wになり
お風呂でも使用できる防水機能と
2台使用でステレオ再生できる機能が追加
連続再生時間は15時間、ハンズフリー通話機能
micro SDカードスロットとFMラジオ受信機能、
内蔵マイクのノイズキャンセル機能が無くなりました


Soundcore Icon Mini
モノラル3W、ポケットにも入るアウトドア向けで
風呂でも使用できる防水と防塵仕様と
2台の使用でステレオ再生も可能で連続再生時間が8時間
ハンズフリー通話機能は無し

この中から使用用途から
まず防水性は必要無いと考えその後値段と持続時間で
15時間連続使用が出来てmicro SDカードで
単独再生もできるSoundCore miniになりました

SoundCore mini コンパクトby Anker Bluetoothスピーカー
【15時間連続再生 / 内蔵マイク搭載 / micro SDカード & FMラジオ対応】
ブラック・ゴールド・ピンク

値段もSoundCore miniでもブラックのみが他色より若干安くて
最安値はアマゾンでAnkerが直売している¥2,399でしたが
ヨドバシ・ドット・コムは¥2,450(税込)ですが
ポイント還元が319ポイント(13%還元・¥319相当)で
実質で¥2,131となりますのでヨドバシ・ドット・コムにて注文しました

これも明日には届きます

久々にダイソーに行ってきたんだけど
USBハブ4ポートを買ってきました

実は今車載冷凍冷蔵庫に12Vファンを2つ追加したので
二分岐できるUSBケーブルが欲しかったんだけど
これはセリア系列に行かないと売ってない

でも他の商品を探しにきたダイソーで
偶然USBハブ4ポートを見つけてしまい
2つ余計にポートが在るけどまぁ目的は果たせるので
購入してきました

108円の商品なので家に戻り早速確認です
取り出してみると外のプラケースは中を開こうとすると
簡単に隙間ができてそこから簡単に開く事が出来ました

ケースを固定するネジ止めも爪も無くただ6本のピンが刺さって
上下のケースが閉じているだけの物です

それでも108円で購入できるとはすごいですね
USBハブ4ポート

中のUSBケーブルの線径もUSB2.0規格品なので
相当品の物の細い線だと思います

ファン2台稼動での電圧降下をテスターで確認しましたが
電圧が12V なので全く問題なさそうです

さすが!ダイソーブランドというところでしょうか

昨日ポーターブル電源G500を30%offで販売するクーポンを
200枚限定でばらまいた楽天市場のミラクルチェ

何かある!
これは処分価格と感じてしまったのですが
今日メルマガが届いてその原因の一つがこれっぽいですね

Suaoki ポータブル電源 G1200 1200Wh AC(1000W 瞬間最大2000W) USB出力4口 急速充電QC3.0

予約販売で価格が129,999円 (税込)!と驚きの価格です
一応商品説明を読んでみましたが
結論から言うと正直な所G500で通常の使用には問題無いと考えます

シガーライターソケットのDC出力に関しては
G500より性能が落ちていました
またシガーライターソケット使用の充電がサポートされなくなりました

ただこれはこれまでどおり
PV入力ポートに16~60Vに昇圧して10A未満で充電可能と言う事です


ではG1200で性能が良くなった部分ですが
まずこれまで使用できなかった300W以上の1000Wまでの家電を使用できますので
電子レンジも一部使用可能みたいです

どうしても出先で300W以上の使用したい家電をお持ちの方には
購入する価値があるかもしれませんが
これに13万円を掛ける必要が在るのかな

次にソーラー充電に最大500Wまで対応してますが
出先に500Wのソーラーパネルを持ち運びますか?

次に1200Whの容量ですが
実は偶然ですが1200Whの容量なら先日我輩が購入した
LONG 12V100Ah 密閉型ゲルバッテリー(LGK100-12N)と同じです
また大きさはこのG1200より小さいです
横幅338mm×奥行170mm×高さ212mm (端子含む高さ:215mm)
大きな違いは重さが34kgとめちゃ重いだけ(笑)

つまり我輩ならこのシールドバッテリーを27,500円で購入したので
残りの10万円で必要に応じで1000W対応のインバーターとシールド用充電器を購入します
それでもお釣りが出ます

吾輩の様にソーラーパネルとソーラーチャージャーを購入したり
走行充電器も追加購入しても良いと思います

車中からの持ち出しは困難ですが車中にセットしておけば
後は延長コードでなんとかなるものですし
持ち出し用にG500等を購入しますね

商品説明のページには防災 停電対策 非常用 発電機 家庭用蓄電池とありますが
この用途で使用するなら家に常駐で設置しても良いので重くなっても問題ないはず
それよりも取り扱いが簡単で安全な従来の鉛バッテリー式のシールド形やゲル式のバッテリーの方が
価格も安いしこれで充分だと考えます

正直ポータブル電源G500を購入してしまいましたが
車中泊での使用目的なら
シールドバッテリーとインバーターでの対応で
全く問題なかったと今は考えています

リチウム電池使用のポータブル電池は高価だし火災の危険性や故障の可能性も高いですし
G1200の様に内蔵しているリチウム電池の本数が増えた分だけこのリスクが大きくなります

もし仮に上記の防災や停電対策、非常用 、発電機、家庭用蓄電池として使用する目的でしたら
なおさら1台ポータブル電源の購入より
シールドバッテリー+インバーター+専用充電器の3つで対応すると思います

G1200の場合バッテリーの寿命が来れば買換えです
高価なポーターブル電池を1つ買うよりは
機能を分けて購入した方が後日バッテリー寿命や故障した機器だけ
買替えや修理していけば長い目で見れば良いと思います
更に必要ならば追加でソーラーパネルとソーラーチャージャーも必要ですね

ほとんどのメーカーはポーターブル電池のリチウム電池交換サービスをしていませんので
故障しなくてもリチウム電池に寿命が来ると他はまだ使用できるのに買替えです

最後に持ち運びがしたいのでポータブル電源がどうしても必要な場合も
G1200を購入するくらいなら他の選択肢をおすすめします
13万円でしたら【限定30%OFFクーポン配布中!】のSuaoki ポータブル電源 G500 500Wh
2台購入しても良いかもしれませんね

でも自動車にも使用されていて安全性の高い
三元系リチウムポリマー電池使用のポータブル電池も発売されています
過去に吾輩もこのポータブル電源とG500の
2台持ち(一台使用中にもう一台は充電に使用)を考えた事はありますから💦
この2台を購入してもお釣りが出ます

年末年始の休みを利用して
昨日の夜にmacOS 10.14.2 Mojaveに更新しました

更新できるハードはもうmac miniのみになっていまいました
HDDのパーテションを3つに区切って
OS2つとTime Machineに分けています

今まで使用していたのがmacOS 10.13.6で
こちらのパーテションは問題があった時のバックアップにして
その前のバックアップがmacOS 10.12だったと思うので
今回はmacOS 10.12のパーテションを消去して
新たにmacOS 10.14.2を新規にインストールしました

その後「移行アシスタント.app」を使用して
これまで使用していたアプリや設定をコピー移行して終了です
ここまでの作業でだいたい2時間半位かかった様な。。うる覚えです

とりあえず就寝前までに見つかった問題としては
設定がコピーされてしまったのが原因で
Google の「バックアップと同期.app」の
Googleドライブの同期先フォルダの設定が以前のパーテション先のままで
この同期フォルダを変更するのに
結局「バックアップと同期.app」とその設定を消去して
新たに同期フォルダを指定しました

昨夜はここまでで終了
電源は落とさずTime Machineで最初のバックアップをとらせます
昨夜は1時くらいに放置して就寝しましたが
Time Machineのログだと今朝6時半くらいにバックアップが終了しました

今朝はMojaveの特徴を知りたかったけど
まぁ一番分かりやすいのはダークモードだけ
macOS 10.14.2 ダークモード

目には優しそうですが
これまでのアプリがまだダークモード表示に
調整されていないので見にくい場合もあります

インストールすると14の新機能を紹介するムービーがリンクされ紹介されます

まぁこれから少しずつ使って慣れていきたいと思います

ドスパラで購入したWD 内蔵HDD Blue 3.5インチ 4TBが届きました

アマゾンの簡易梱包に比べるとエアクッションも入っていて
丁寧に梱包されている感があり安心感があります
ドスパラ

クッションを取ると今回購入したHDDが箱入りで入っていました
考えてみるとこれまで箱入りの内蔵HDDを購入した事なかったですね
ドスパラ

底にもちゃんとクッション材が敷いてありました
ドスパラ

HDDの箱を開けてももちろんHDD保護のクッション材に包まれています
ドスパラ

動作確認を兼ねてCrystalDiskInfoで状態確認しました
電源投入回数1回でまぁ問題なさそうです
WD 内蔵HDD Blue 3.5インチ 4TB



おまけ

評価が良かったので今回一緒に購入した上海問屋の単二アルカリ電池 229 円(税込)

4本組で1本あたりダイソーより安い価格ですが
使用推奨期限と思われる刻印は2023.11で
よっぽどの粗悪品でない限り通常のアルカリ電池は
製造から5年が使用推奨期限とされているものが多く
これも先月製造された電池の可能性が大きいです

現在使用している4TB HDDの残り空き容量が5GB位になり
そろそろ整理して年末年始の休みの間に新たなHDDに切り替えて整理しようと思っているこの頃

未使用の外付け4TBハードディスクを予備で(10,680円で購入)持っているのに
内蔵WDの4TB HDDが8千円台とめちゃお安くなっていてお得感があったので
衝動買いしました

価格ドットコム使用してクレジットカード使用での最安値を確認する
8,835円でした

他に8,840円でAmazonとノジマオンラインやソフマップの量販店の他にも多くの店で販売されていましたので
その中から今回はドスパラで購入しました

実は8,840円から期間限定でWEB通販専用のクーポンが使用できて300円引きになり
更に持っていたポイントもあり今回全て使用しました
注文時同時にお試しで上海問屋 DN-68296 (アルカリ乾電池 単二 4本組) 229 円(税込)も注文して
合計¥9,069からクーポン利用(¥-300)とポイント利用(33 P)で合計¥8,736(内消費税 ¥647)の支払いでした

300円引きなので電池をタダで頂いた上に
HDDから71円引いてもらいHDDも最安値で手に入れたとも考えられる(笑)

Google Drive
Google Driveを使用してスマホの写真を同期していますが
今朝からスマホで撮影した新たな写真データが同期されなくなり
ふとメニューアイコンの列にGoogle Driveのアイコンが無くなっていました
Googleドライブ

なぜ?って感じでアプリケーションフォルダを確認してみると
Google Drive.appがエイリアスに変わっています

エイリアスを選んでオリジナルを表示しようとしても
オリジナルが無くなっています

タイムマシンで確認すると
昨年の12月24日の段階でエイリアスになっていてオリジナルも消えています
しかし昨日までのスマホの写真ファイルは同期していました

ネットで調べてみるとどうやら
「Googleドライブ」アプリのサービス終了と関係があるみたいです

簡単に説明すると
昨年の7月にGoogleはMac/PC版「Googleドライブ」アプリを
同じ機能を持つツール「バックアップと同期」に置き換えると発表していて
12月11日に「Googleドライブ」アプリのサポートを打ち切り
2018年3月12日には完全にサービスを終了し「バックアップと同期」に移行するというもの

そしてアプリケーションフォルダを再度確認すると
「Google のバックアップと同期」アプリが午前中に追加されていました

もしかすると再起動をしたら自動的に切り替わったのかもしれないのですが
その前に気づいてしまったのか

もしくはHDDをパーテションで分けてOS10.11を残していて
そこには「Google のバックアップと同期」アプリが昨年の11月には存在していました
Googleドライブ


その不具合なのか判りませんが
ログイン項目にも「Google Drive」が開く設定で残ったままでした

どちらにしても「Google Drive」から
「Google のバックアップと同期」をログイン時に開く設定に変更しました

「Google のバックアップと同期」を開いてみると
これまで通りメニューバーに見慣れたアイコンが表示されて同期されましたので
これでめでたしなのですが調べると
「Google のバックアップと同期」は自動でアップデートされず
自分でダウンロードしインストールする必要がある
ので
この変更を知らない世界のユーザーは3月13日以降に慌てるんでしょうね

吾輩はアップデートした記憶がないのだけど猫なので忘れているのでしょう💦

今週に入り夕方にMacでメールチェックをすると
ヤフーメールだけメールアプリから接続できない

Incorrect username or password.

Incorrect username or password.

最初の内は指示通りパスワードを再度入力するのだけど
まったく変わらず同じ案内の繰り返しです

そしてしばらく放置していると忘れた頃に普通にログインできます

単純にサーバーに負荷がかかっているのだと思うのですが
Yahoo!メール新着情報の障害・メンテナンス情報にも

今年に入って「メール受信遅延解消のお知らせとおわび」は無いので
このログインエラーの原因はなんでしょね

Macで以前重宝していた多機能型リネームソフト「Shupapan」
Shupapan

これまでOS X 10.11 El Capitanを使用していた時には
ファイル名を書き換え後によく強制終了していましたが
それでも便利なので騙し騙し我慢して使用していました

週末にmacOS High Sierraをインストールしたのですが
その後にファイルを整理していた流れでファイル名を一括変換してみると
何と!Shupapanの強制終了が起きません

その後も何度かリネームしましたが強制終了が発生しません

どうやら少なくとも我輩のmacOS High Sierra上ではShupapanは安定しています
macOS High Sierraインストール画面

Shupapanを使用していない方は便利なソフトなので
これを期に試しに使用してみてはいかがでしょうか?

午前中にUD-303SM/A [IDE USB2.0変換アダプタキット]の動作確認が終わり
これで準備はできました

午後になり依頼があったお宅にお伺い
依頼のあったG4は家に在るタイプと同じでした

急に電源が入らなくなったG4で
HDDに保存してあるデータを取り出したいという依頼

まず確認しましたがやはり電源は入らず
電源コードを交換したり
電源10秒長押し後に再度押し
PMUスイッチリセットなどを試しましたがピクリともしない

どうやら電源ユニットか電源ボタンの故障と考えられるけど
今回の依頼は修理では無くデーターの吸い出し

箱を開きHDDを取り外そうとするのですが外れない
隠れているネジとか在るのかな?と確認するがそのような物も無く
最終的にネットで確認するけど外し方に問題は無く
単純にガッチリとハマっているだけの様

人様の商品で衝撃に弱い取扱い注意のHDDですから
力任せに取り外す訳にも行かず慎重に行います

その後何とか外れて一安心

2ドライブでそのお宅で現在使用しているiMacを使用してマウント

マウントされたファイルをiMacにすべてコピーします
これを2ドライブ分行いました

システムが入ったドライブは
システムファイルのコピー中にエラーが出ましたが
システムファイルは必要無いので問題無し

コピー中の空いた時間に
新たに購入するMacの相談や
G4に使用していた2つのモニターやキーボードの動作確認

聞くとG4は2台在るのでそちらにモニターを接続して確認して見ると問題無くまだ使用できます
今回電源が入らなくなったG4に入っていたHDDを
もう一台のG4に移植しメモリーも空きスロットが在ったので
メモリーも動作するG4に移植し2GBになりました

G4に4台のHDDをセットするのは自宅のG4で実行済みなのですが
ジャンパピンの設定を覚えて無く
何度か設定を変更しましたが増設した2台は認識せず

こちらは次回お伺いした時の必要なら再設定するという事で終了です
次回は年明けに新たに購入したMacとネットワークの設定依頼です

趣味の延長でお伺いして不具合の相談に応じているのですが
仕事で使用しているのでちゃんと請求して欲しいという事で
今回恐れ多いのですがこちらから値段を提示して頂いてきましたm(_ _)m

今回2箇所指等を切りました💦


さて家に戻りHDDのジャンパピン設定を確認してみると
ネットで検索してもG4に4台のHDD設置の時の設定自体が見つけられなかったのですが
全てのHDDをケーブル・セレクトの設定にしていました

間違って注文してしまい
土曜日の午前中までに欲しかった為に
その日時指定が出来たヨドバシ.comで
UD-303SM/A [IDE USB2.0変換アダプタキット]を注文しました

今回はゆうパックで
お隣県新潟からの発送でしたが
履歴を見ると7時30分に地元郵便局を通過し
家に配達されたのが10時30分とギリギリセーフって感じですかね
ゆうパック履歴

届いたUD-303SM/A [IDE USB2.0変換アダプタキット]外観

箱を開いた中の状態

コネクターの形状
写真で見ると上下に2.5"用と3.5/5.25"ドライブに分かれています
UD-303SM/A [IDE USB2.0変換アダプタキット]

ACアダプターはUD-505SA [SATA接続3.5/5.25"ドライブ専用 USB2.0変換アダプタキット]には
12V3A出力の物がついていて4pinの電源コネクタにSATA用の変換コネクタが付いた物でした
UD-303SMには12V2A出力で単純に4pinの物でした

まぁ一部のSATA接続HDDには4pinの電源のみの製品もあるそうなので
その対応の為にこの様になっている


午後に使用する前に家で接続の確認で
実際にMacに接続してみると全く認識されない

最初はOSの問題かと思いMacBookProに入っているWin10にて再接続してみます

今度は意識されるけど画面にマウントされない

困った〜なぜ??て感じですがこれは認識はされているので
単純にWindows10がMacのHFS+フォーマットに対応していないのが問題
だと思います

今度はMacBookProのMac OSXにて再接続

すると今度は普通に認識マウントされ中も開く事が出来てほっと一安心
最初に認識しなかったMac miniにも再接続してみると
こちらも問題無く認識されマウントされました

昨日注文したタイムリー GROOVY UD-505SA(SATA USB2.0変換アダプタキット)が届きました
タイムリー GROOVY UD-505SA

早速手元に在るATA HDDを使用して接続の確認です

手持ちの外付けHDDドライブからHDDを取り出しました
13GB ATA HDD

所がです
箱から取り出してコネクターを見て形状がおかしいことに気づきました
どう見ても取り出したHDDのコネクタ形状と違います
コネクタ形状

やっちゃいました

ATAとSATAを同じ規格と勘違いしていました

袋を破る前に気づいて躊躇はしたのに
とりあえず合わせてみようと袋開けてしまい返品不可にしてしまいました

あ〜あ
商品を間違えてガックリ
更に袋を開いてしまい返品不可にしてしまいまたガックリ

何やってんでしょう
注文する時にもっと慎重に調べてから注文したら良かった



IDEとSATA パソコン初心者講座よりメモ

IDE・・旧規格 別名:ATA、パラレルATA、ATAPI(光学ドライブ)
SATA・・新規格 別名:サタ



仕方が無い
どうしても土曜日に変換ケーブルが欲しいので
再度アマゾンから注文しようとすると
昨日はお急ぎ便で翌日配達できたのに今日はその選択肢が無く
なっています

昨日お急ぎ便で注文したこの商品も
今日はお急ぎ便を選べなく日時指定での最短は翌週の月曜日からになっています
年末で忙しくなるからかな?

そこでAmazonは諦めて
土曜日の午前中指定で注文できる所を探します

まずはこれ以上の出費を抑える為に
ポイントで買えないかと楽天市場を調べますが
こちらも配達日時指定の最短はAmazonと同じでした

次にヨドバシ.com
こちらは配達日時指定が土曜日からできたので間に合います

良かった〜

最初商品はAmazonで安い方のUD-301S/A [IDE USB2.0変換アダプタキット]¥1,419で探したのですが


ヨドバシ.comでは
UD-301S/A [IDE接続3.5/5.25"ドライブ専用 USB2.0変換アダプタキット]¥1,780で
上位モデルでも
UD-303SM [IDE接続2.5/3.5/5.25"ドライブ専用 USB2.0変換アダプタキット]¥1,890で
購入できます

違いはIDE接続の2.5ドライブにも接続ができる

Amazonでは上位モデルは¥1,625で価格差が206円ですが

ヨドバシ.comでは価格差が110円だったので
それなら上位モデルをということで
必要も無いのに2.5インチドライブにも対応している物を注文しました

在るきっかけから土曜日にお伺いして
ATA規格のHDDからデータを取り出す事になりました

最初ATAというのをうっかり忘れていまして
以前購入したガチャベイを持ち込んで
取り出したHDDをセットしてデータを取り出す予定でしたのですが
これではデータを取り出せないのです

そこで最初はHDDをお預かりして
家に戻ってG4に取り付けてデータ取り出しするかと考えましたけど
二度手間になりますし。。

そこでATA接続からUSB接続出来るようにする変換ケーブルが必要になって
ネットで調べてAmazonで注文しました

ネットで知らべると
丁度同じ症状で使用されていた商品を注文しました

動かなくなったPCからHDDを取り出しSATA-USB変換ケーブルを接続したら無事データを救出できました。

偶然ですが以前もチェックしてたタイムリー GROOVY HDDをUSB SATA接続2.5/3.5/5.25"ドライブ専用 UD-505SAですが当時(2013/12/16 ¥1,436)より販売価格が¥1,337と安くなっています

DVDドライブ等にも対応していて電源も2Aまで対応しているので
今後使用する機会が出てくると思うので
この機会にタイムリー GROOVY HDDをUSB SATA接続2.5/3.5/5.25"ドライブ専用 UD-505SAを購入しました


これはUSB3.0対応の新商品が出ているからだと思います
Groovy HDDをUSB3.0 内蔵型ハードディスク、ブルーレイドライブ対応 UD-3000SA


USB3.0まで必要ないので安さ重視
丁度プライム会員解約前だったのでお急ぎ便で明日には届くという
すごいね!

以前OS X El Capitanにした際に
新たなセキュリティシステムSIP(System Integrity Protection)が採用されて
システムに変更が加えられないようにデフォルトでONになっています

その為これまで使用していたAsepsis v1.5.2を
通常インストール出来なくなり
開発者もAsepsisの開発を中止しサポートも終了しました
Asepsis is a system utility for prevention of .DS_Store files

それでもAsepsisを使いたい方のために
開発者はセキュリティシステムSIPを無効にする事で
Asepsisをインストールし実行できる方法が公開されています

ただし開発者も「システムインテグリティ保護を無効にすることをお勧めしません。あなたのマシンの安全性は低くなるかもしれません。それは完全にあなたの決断です。」と自己責任での使用を確認しています

まずリカバリーモードでOSを起動する必要があります。
これを行う為にマシンを再起動しCOMMANDキー + Rキー押し
これをAppleのロゴが表示されるまで押し続けます

起動後「ユーティリティ」メニューから「ターミナル」を選択し開きます

開いたウィンドウで、csrutil disableと入力してReturnキーを押します
次にrebootと入力してReturnキーを押し再起動します

再起動後インストーラがシステムのバージョンチェックを無視できるように
ホームディレクトリにファイルを作成します

再度「ターミナル」を開きtouch ~/.no-asepsis-os-restrictionと入力し
その後、ダウンロードしたAsepsis v1.5.2をインストールします

イメージファイルを開きAsepsis.pkgをクリックしインストールします

通常ガイダンスに従ってインストールを行い再起動するだけです

詳しい方法はOS X El Capitanで「.DS_Store」を作らせない&削除する方法を参考にしてください

さてインストール後実際問題無くAsepsisが動作しているのかは
後日「.DS_Store」ファイルが作成されていたら失敗なのですが
そんなに待てないという方の為に「ターミナル」を開いて診断することが出来ます
asepsisctl diagnoseと入力してReturnキーを押します

Your Asepsis installation seems to be OK」と表示されれば問題無しです

これで「.DS_Store」ファイルは新たに作成されていません

もし他の表示が出た場合はインストール失敗もしくはシステムが後日更新されていて動作していない場合があります
この場合は再インストールを試してみてください

そして今現在すでにもうある「.DS_Store」ファイルをホームから削除する方法ですが
「ターミナルで」find ~/ -name .DS_Store -exec rm {} \; と入力してReturnキーを押します

もしくはアプリ(DotCleanerやMacForkCleaner等)を使用して消す方法があります

OS X El Capitanが公開されて大分経つのになぜいまさらこの情報?と
思われるかもしれませんが
吾輩の持つ2台のマックのうち一台が以前何度インストールをしても失敗していたのですが
原因が解らずその時はサブ機だったので放置して今現在に至ってました

今回ターミナルで診断コマンドを実行することによって問題箇所が解り
そのファイル類を全て消去してから再インストールすることによってやっと成功しましたので
その覚書も兼ねています💦
