root@SIL:~# fdisk /dev/sdb

The number of cylinders for this disk is set to 19595.
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)

The partition table has been altered!

Calling ioctl() to re-read partition table.

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.

起動

INFO LED が 25 を表示し、HDD がゴリゴリ言っている。
しばらくして「ピィ」といってリブートをはじめた。
またまたしばらくして POWER LED の点滅が止まった。

バージョン確認

ファームウェアバージョンは 1.03。＼^_^／

まっさらな状態から、標準ファームの HDD 作成成功。

メリー・クリスマァース！
