Defraggler Health Report, what's my next step?

Recommended Posts

Hello everyone!

 

Yesterday, when I booted up my Compaq Presario CQ5210F, it went straight to the Diagnostic tools and told me that while everything else was fine, my hard drive was facing 'imminent failure'.

 

Well, I've managed to save all of my important files now, and I've done a reading of the disk with Piriform's Defraggler, and this is what it came up with:

So apparently the problem is that my 'Relocated Sectors Count' and 'Reallocation Event Count' are bad or incorrect.

 

From what little I've read there might not be a way to actually fix them, but to block them? How would I do that? And is there anything else I could/should do to try and save my hard drive?

 

Lastly, if nothing else can be resolved, how long would you say it might last? Supposedly I need to keep checking and see if those numbers increase on the chart?

You have done the sensible thing and backed up your data, no matter what happens you have got your data :)

 

As you say keeping an eye on the figures to see if they rise is the thing to do.

 

An explanation here for those wanting to know what this is about.

 

Reallocated sector means that your harddrive found a bad sector, and swapped it with a 'reserve pool' of sectors. After this swap, the medium should be free of bad sectors to the operating system. Its a technology designed to make failing sectors on the harddrive cause no trouble for the operating system because it'll just swap a new one whenever it finds that a particular sector is becoming weak (because it takes more time to read that sector than normal).

 

So "replace that drive now" may be an overreaction. You do need to make sure you have proper backups however, but a drive with reallocated sectors could last for years in good operation.

 

One exception to this is, if the number rises continuously, like every day it jumps a few. Then you've got a failing harddisk because once the 'reserve sector pool' runs out it cannot hide the bad sectors anymore from the operating system. And remember, a drive can only reallocte a sector if you write to it, or it can still be read from. So sometimes its necessary to do a zero-write on the drive to be able to let it swap the sector. Should the number not increase after a zero-write, your harddrive found no new potentially bad sectors that it wants to swap.

Thank you for this information. I've done a virus scan of the computer and taken out a few things, and I notice that it might be a bit faster now. Also I've done a health check and the number hasn't gone up since then. Not yet anyway. Is it possible it was a deadly virus and not a ruined hard drive, or was that probably a coincidence?
