HDD Failure - read / write errors

[Ruff.Hi]

I got a report that a drive in my server was throwing read / write errors.

I swapped the drive out and the new (84hrs old) drive started to throw errors too.

I don't think this is the drive ... I think it might be the hardware connecting this drive to the motherboard. I am using a mini SAS (SFF-8643) cable to connect my 8 drives. Could I have a bad connection here? Wouldn't that throw a different error?

Wouldn't that throw a different error?

[Ruff.Hi]

Fair enough. Thanks for those links. I have consumed most of them and do have a phalanx of scripts that run.
