Seagate ST3500418AS, showing Reallocated Sectors

[Franc Zabkar]

The SMART Data no longer lists any thresholds for that drive but does with
all the others, that's using Hard Disk Sentinel, must be a Smart Bug or a Hard
Disk Sentinel one.

FWIW, the SMART attribute thresholds and attribute values are returned
in separate blocks of data.

This example is for a Seagate 320GB PATA drive:

As its a Back up drive its away's plugged in, but I can turn it Off and On
with USB Safety Remove software.

I think you can probably work out there is no definitive answer. I would
point out that the firmware has the reallocation function built in and it is
doing exactly what it was designed to do. The only quibble seems to be the
threshold which the manufacturer believes is around 100 as opposed to 0 that
the RS insists is the limit.

Jeez that's ugly I fixed up a guy's HDD yesterday. He brought his
PC over on Friday; suspected HDD failing, a mate of his had had a
looksee and managed to delete the partition info (NTFS / Win XPP). I
dropped into my test box and had a looksee; got ALL the data off it for
him...

TestDisk found no partition info, so I just wrote in an NTFS one, and it
then found the MFT. And subsequently all the files. I believe *some*
files will be corrupted and told him that. Charged him $180, and he
gave me an extra hundy he was so rapt to get his data back!

Worth mentioning that it could just as easily be done under Windows -
but it's a right PITA setting up anything other than Windows 7 in a
short space of time. And Windows 7 doesn't run (at all really on the
test box (an old 1600Mz, 512Mb PC). On Linux, I just throw in the Ubuntu
CD, type in the info it needs, and it loads on up. Put my apt-get
script in from my pen drive, and about two hours later, it's up. (While
Win 7 could do the same, it wouldn't run on that hardware. XP would,
but requires about 20 times user intervention - vs. 2! - and of course,
no "activation" required, nor about 8 reboots or whatever it is).

PS: not sayin I don't have problems on my Ubuntu test PC - it
continually drops out of 1024.768 back to 800.600 (that's the worst one
for me). Hoping the 10.04 beta will sort that (waiting until the 23
when my ISP month cycles (several gig over my monthly limit already)).

I never said that. I JUST said that a few more than 0
isnt that uncommon and nothing to worry about, but
more than that is definitely a problem somewhere.

This is because many recent USB->SATA bridges support SAT (SCSI/ATA
Translation) standard or vendor specific ATA pass-through commands.

Interesting, good to know.
