Topic: Bad Blocls on HDD?

[David Trask]

Hi,

I'm getting a message in flexbackup to the emailed log that includes this message...

DUMP: read error from /dev/sda5: Input/output error: [block 28073152]:
count=4096

How can I fix this?  I've run badblocks....nothing seems to show up....I want to run fsck but I can't get /dev/sda5 unmounted...says it's busy.  Should I be concerned and how can I fix this?

Shutdown your machine and power it up in single user mode. This way you can check your /dev/sda5.

Good luck.

I did a shutdown and forced "fsck" using the "shutdown -F now"  command...yet I'm still getting this report......any ideas?

Sorry,

I'm out of suggestions..., anyone else

[Blake H.]

Did you ever find a solution to this? I just started getting the same messages in my backup job.
