Re: Does "I/O error" mean hardware problem?

200 Multi_Zone_Error_Rate 15265539
I just checked a system here with a 1 year old 500GB WD BLUE SATA II
drive on a Sil3512 based PCI card and both 199 and 200 have a value of
zero. This would seem to indicate you have a problem with the cabling
between your drive and the controller. Considering this is a laptop,
I'd guess it has been dropped at least once, loosening the cable
connector either at the drive or the PCB socket, causing intermittent
contact. If this Dell 6400 has a direct connection between the drive
interface and a PCB mounted SATA socket, I'd guess than once or more
traces on the PCB have been cracked, or a pin within the socket has been
cracked.
CRC errors indicate a transmission problem on the interface conductors.
Whether the problem is either of the two things I mention above, you
definitely have a problem with the interface between the drive and the
SATA controller.
