Hi

I tested yesterday my 120GB barracuda 7200.7 drive, which is a router
hdd working 24h, this test let me know that i have a few dozen blocks
under 500ms (those browns, not the "hardcore" :P red ones), so im
curious..what will be better; to zeroing and remap this drive to be
sure nothing gonna happend in next few months or leave it as it is ? i
have no experience with such "color typed" block, so i dont know what
can i expecting on my drive
Thank You, and sorry for my broken english

Regards

This test huh? You sure it wasn't the other one? Strange, man.

Using what to test it ?

Its likely better to replace it before it dies depending on how you tested it.

And you should backup what matters immediately too.

And we dont know what you used to see that.

What are you talking about??? Time is not a way to describe
HDD sector characteristics.

The diagnostic he's using, MHDD, can be made to scan a hard drive
sequentially and report in graph form the number of milliseconds
needed to read a block of 256 sectors. For blocks that took less than
3 ms to read, a white square is drawn, but a brown square is drawn for
blocks that needed > 150 m but < 500 mto read, while anything that
took over 500 ms is represented by a red square.

I see. I expect this is supposed to display areas where retries
caused slowdowns.

Zeroing does nothing for HDD health. If the drive has a
problem, it needs to be replaced.

Side note: Remapping can be done today by running a full
surface scan (or long SMART selftest, which does the same
and some more tests), and, incidentially, in no other way,
unless there are pending sectors in the SMART attributes.
Then you need to zero these (or the complete drive).

You say the exact opposite at the bottom and got it right at the bottom.

Not necessarily.

Zeroing does nothing for HDD healt. It can help reallocating a sector
(ehrn ECC and retirs fail to read it), but that will not correct any
mechanical or electronic problems and reallocation does not improve
health. It just hides the symproms. For many problems that is enough,
but for some it is not.

Well, let's say that if the drive has electronic or mechanical
problems, then it needs to be replaced. A reallocated sector is
not necessarily a problem, the occasional reallocation is notmal
in modern HDDs. I should probably have been more specific in my
statement.

A second way to phrase it would be to call the occasional
reallocation a transient problem and other things persintent
problems. Then zeroing would do nothing to correct persistent
problems, but can help with transient problems.
