Today I've just finished HDD scan with recoverdisk and there were 3 bad
sectors.
It was stuck on them for a 15 hrs, until it finally did read whole disk,
Then I've run it again and it read HDD 100%, without a glitch.
I don't know was it a firmware realocated those or those looooong read
attempts fixed a thing.
Then reboted into single user and run fsck, which detected a LOT
unreferenced inodes at /usr, which it successfully reconected.
Finally fsck again to get clean, non error output.
Could that caused a panics?
PS: I'll run a memtest86+ when I get some time. For how long do you advise?
