Re: Strange ATA problems

Hi everybody.

Today I've experienced a very strange problem.

I have a CD/DVD drive connected via USB,... and while woking the system
suddenly freezed (at least those processes that tried to access the
hardsisk).

Looking at dmesg it showed me this:
ACPI: PCI Interrupt Link [LNK3] enabled at IRQ 18
ACPI: PCI Interrupt 0000:02:00.0[A] -> Link [LNK3] -> GSI 18 (level,
high) -> IRQ 18

So I've plugged out the USB connected drive and then those processes
continued.

Anyway, now I got the following stuff:

ata1/sda is my harddisk (at least one of them)
What do does errors mean? Is this probably a hardware failure?
And how can the CD/DVD problem relate to this?

Any ideas?



smartctl output of those harddisk(s)?
