Which Disk is Failing - Backups fail but disks are healthy RRS feed

  • Question

  • My EX470 has been running fine for 18 months with 2 additional 1 TB drives (in addition to the stock 500MB drive). The other day my pc backups began failing with the event log saying I have an I/O error accessing drive D: The exact error:

    Unexpected error 0x45d from ReadFile on D:\folders\{00008086-058D-4C89-AB57-A7F909A47AB4}\NANCYPC.C.VolumeClusterLatest1.4096.dat: The request could not be performed because of an I/O device error.

    Of course all drives show up as healthy.

    Is there a way to find out which of the physical drives is causing the problem - or which is being accessed when the problem occurs?

    I'm not sure running chkdsk d: /r would resolve anything given there is no monitor to view the results on (I believe the /r option forces chkdsk to run before windows is booted, correct?). And I'm not sure how long it would take to run.

    Pulling the drives and running chkdsk on them individually is not an option as I have no spare SATA bays on my other pc's to put the drives.

    Thanks for any help.
