ハードドライブがどんな状況でトラブルを起こしたのですか？

まずFWを書き直す前にハードドライブの何処が悪いかの確認はしましたか？

もし自分での修理をとお思いでしたらロシアからPC3000か中国からサルベーションの機材を購入しないと修理はできないと思いますよ。費用的には１００万円を超えると思います。

How did your drive die? Before you rewrite the FW, did you check everything else to make sure the FW was the problem? If you are thinking about fixing on your own, you might want to get the PC3K or Salvation tools. You might be looking at over $10K...
