Kernel Messages about Hard Drive?

I enabled logwatch on my server. I noticed the following messages in the logwatch email :

--------------------- Kernel Begin ------------------------

1 Time(s): hda: ATAPI reset complete
1 Time(s): hda: irq timeout: status=0xd0 { Busy }
1 Time(s): ide-cd: cmd 0x3 timed out
1 Time(s): ide: failed opcode was: unknown

---------------------- Kernel End -------------------------

Is this indicative of a hard drive failure?

Although it could also be caused by a bad cable or even a very buggy controller driver.

So try checking/replacing/re-seating your cables first and then perhaps download a diagnostic utility and give the drive a full test.

Make sure you have a decent backup first! If it is a faulty drive this (or even just re-powering it) could push it over the edge.
