Maxtor Diamod max 10 6L200 ×２

LS-WSGL/R1
京都駅の南のショップで、Maxtor Diamod max 10 6L200 を２つ買ってきた。

同じ型番であるが、製造時期が違うので、ラベルが微妙に違う。
CHS は同じだろうな。
RAID1 にするために同じのを２つ買ってきたのに、 ブロック数が違ってたら笑うに笑えない。

１台目の HDD に標準ファームのコピー

なにはともあれ、標準ファームをコピーする。

SATA2 に標準ファームの 2.5 インチ HDD を接続、
SATA1 に右側の 2005 年製造の HDD を接続、
LS-WSGL を起動する。

raid_rebuild.sh の実行

いろいろ散歩していて、 /usr/local/bin/raid_rebuild.sh を見つけた。
