HDD 異常

ビデオサーバ兼ホームディレクトリサーバにしている HS-DHGL の HDD、 SAMSUNG HD103UJ が　ERROR を出すようになった。

新しい HDD の導入

仕方がないので、京都駅南のショップで、 Western Digital の 1.5TB HDD WD15EADS を買ってきた。
1.5TB HDD が１万円弱。安くなったもんだ

USB で接続

HS-DHGL は、エラーを出し続けながらも動いてはいるので、 HS-DHGL に USB で接続

Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.


The number of cylinders for this disk is set to 182401.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

この先記録なし

ここから先、試行錯誤しすぎて記録なし。
途中で近畿最北端にも行ったし（意味不明）

結局 HS-DHGL だけでは新しい HDD が構築できず、
まぁ、エラーの出ている HDD で動いている OS ではまともに動かなくても仕方がない。

LS-XHL+ハックキットに USB で HDD を接続、
上記フォーマットまでを実行、
バックアップからシステムを戻して、
できあがった HDD を HS-DHGL にセットして起動
