初代OBSのディスク挿換

まぁ、手順メモです。

【概要】
・OBSに入れていた40GBのディスクをUSB外付け箱用に取り出して、
　ノートPC(hobbs)のバックアップにする。
・代わりにUSB外付け箱に入っていた6.5GBを初代OBSへ。

【OBS状況】
hcube:/home/shibata# fdisk /dev/sda
The number of cylinders for this disk is set to 4864.
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)
Command (m for help): p
