[Bug 643705] Re: extremely slow ubuntu 10.04 slow disk check at boot time

[Theodore Ts'o]

This really sounds like a hardware problem.   First on my suspect list
is your hard drive.  Have you tried using smartctl to get a S.M.A.R.T
report?  Or have you tried running diagnostics?    During the part of
the file system check where the completion percentage is going very
slowly, do you hear any kind of regular clicking or grinding or whiring
noises from the disk that sound unusual?   That could be the sound of
the disk trying and re-trying to read certain disk sectors, again and
again and again, until it finally gives up and moves to the next disk
sector (which is also bad).  That would explain the very slow progress.
