I wouldn't use a drive anymore which has started reallocating
sectors, well which has reallocated sectors all.
It's on it's way out for sure.
However, I am interested in how you are able to know that sectors on
golinux's disk have been relocated - from the information provided to
this mailing list. I know it's possible to see that in the SMART data,
but I didn't see that posted. Are short reads always surface errors?
Best regards,

Simon . . . SMART data attached. I hadn't noticed this before . . .
sounds ominous . . .
SMART Status command failed: scsi error medium or hardware error (serious)
Note that I ran this from GSmartControl not a terminal.
I think it's because you are connected via USB. From my experience, the
best way, possibly the only thorough way, to diagnose a SATA disk drive
is connected to a SATA controller directly, which is why I really like
notebooks that have eSATA ports.
About my above question to Andreas, I am interested to learn if this is
indeed the case: short reads indicate surface error.
I have gotten this error over USB before. When connecting the same disk
to a known working SATA controller, I was able to use it fine and no
errors occurred. USB -> SATA controllers/cases in my experience are of
poor quality and fail before the disk does. I am not one to hang on to a
failing disk, but you sound thorough. So I'd suggest using a SATA
controller to read the SMART data and run other diagnostics.
If you are a data hoarder and like disks, I'd suggest getting your hands
on some hardware that has a SATA controller. It doesn't need to be fancy
or new. Pretty much any working desktop is fine.
In your SMART data:
Reallocated_Sector_Ct = 1
However:
SMART overall-health self-assessment test result: PASSED
Reallocation, to my knowledge, should happen in the background. It's
*possible* that the reallocation event and the FS corruption are unrelated.
If that count keeps going up, don't use the disk. Eventually the surface
will not be able to store data/be magnetised.
I am keen to learn more about disk recovery. So please, anyone, correct
me if I am wrong.
Best regards,
Simon
