Re: Need help with "reallocated sector count"?

Arno, Rod (no quatiton mark :-) ), Franc,
Thanks you for following this topic and keeping replying.

So, as overall when you looked at SMART values, i want to summarize
what i got in that topic?

1- There are 98 reallocated bad sectors but there's no unallocated as
a threat of data loss? Right?


2-ID Attribute Description Threshold Value Worst Data Status
05 Reallocated Sector Count 36 98 98 98 OK: Value is normal

That means there are 98 reallocated sectors, but still couldn't
completely understand for Seagate what "threshold - 36" means? It
shouldn't be percantage, does it mean that i'm allowed to allocate
100-36 = 64 bad ones? (frustrating)

3- The other SMART values are fine as stated by many programs. Right?

4- A "reallocated sector count" shows the amount of reallocated /
replaced sectors silently while the drive is operating. When the drive
has a problem with sector, first it tries to replace that sectors with
a "spare" sector thus a "reallocated sector" statistic is updated.

If the sector is completely unreadable or unreallocatable, you see it
as "bad" marked in surface scan tools like Seatools. Did i understand
correct?

5- Though a drive has "reallocated sectors", if it can read every data
(checking with several disk reading utilites), it doesn't have a
unallocatable / unfixable bad sectos which are the reasons of real
data loss.

Those 5 questions are the ones i see answered them clearly.

Again, thank you for following and helping. Very helpful...

Regards.
