In /var/log/messages, smartd is reporting:
Device: /de/hdb, 3 Currently unreadable (pending) sectors
I'm trying to figure out where they are and how to fix them or mark
them as bad.
Took the machine down last night and ran SpinRite 6 on it. It
reported no problems on the drive.
Ran the smartctl tests, both short and long, and they finished
without errors.
There's a great HOWTO on fixing bad blocks at http://
smartmontools.sourceforge.net/badBlockHowTo.txt, but I don't seem to
have any bad blocks to fix.
Ideas on what else I can do to find/fix the errors?
I'm downloaded the Western Digital diagnostics now and will see if
that gets me anywhere... nope. Long and short tests all report no error.
Would be glad to post the full smartctl diagnostics if anyone would
like to read them.
Since all the tests pass, I wondered if something else could be the
source of the problems, like a driver, but SMART should be bypassing
OS drivers and speaking to the hardware, I think.
The drive shows Power-On hours over 33,000, so I'll plan on a
replacement in any case, but I'm curious how to troubleshoot from
here. Ideas welcomed.
