Hd sector sparing

Most of todays HD's have the ability to auto spare a defective sector.

If this activity takes place and I run a product like scandisk can I see a sector marked bad?

I get the impression the answer is NO.....all sectors will show good.

If the auto spare activity takes place and all the spare sectors for that track are in use.....what happens?

When there are no more spares then

In reply to: Hd sector sparing

Then chkdsk and the like will start to report bad sectors. The entire issue is well documented so I'll stop here and wait to read why you asked.

Your right.

It is well documented.

In fact there are so many hits on google about this that you can get any kind of answer you want.

As to why I ask.....just trying to make the big picture a bit more clear.

I'm not having any HD issues....that I know of.

I get the impression that I could have a HD slowly dieing but because of the auto spare function I would be blind to this.

That a surface scan tool chkdsk/scandisk might show all sectors good as long as the auto spare function had spare sectors that true?

To complete your research you would read about S.M.A.R.T. and get a tool that reads that from your drive.

-> Let's skip past all this and repeat what we've learned in the forums. Ready? Here it is -> "We only lose what we didn't backup."

In reply to: True.

The picture just became a bit more clear.

SMART reader....that is an option....but it looks like I would need to keep a chart.

Backups....been doing that from day 2.....on day 1 I got my head handed to me in a basket....never again.

Again thanks.....another piece of the puzzle.
