Windows 7: Disk error check

Disk error check

I used the Disk Error Checking fucntion under the Tools tab in Disk Properties. And noticed that whilt my both 2TB drives are of the same make and model, one checking is much faster than the other by a mile.

Could this because the checking does not include area which files are already written on?

Can anyone throw any light on this.

I did this, because, when I used Sea Tools from Seagate to check one of the drive, it failed, because the number errors exceeded the limit of the checking software. But running the check using the above fucntionality in Win 7, it passed. So may be the Disk Error Checking of Win 7 does not cover the used areas of the disk!!

Any help would be greatly appreciated.

cheers

I would think it is rather the other way around. It does not check unused space. But I am not 100% certain. Does the timing somehow relate to the amount of data that is on the disks.

So maybe my theory is correct. But as I said, I am not 100% certain. But why should the disk check check freespace.

Maybe you want to run a chkdsk /f in command prompt and see what that yields.

My understanding is the more errors check disk finds the longer the process takes.

How much time difference are we talking about.
Are you running a disk check and then rebooting and running the other disk check.

I'm I going crazy ffrree or did you just update your System Specs?

Are those hard drives exactly the same. Same part number and same speed. (5400 rpm)(7400 rpm)??

My system spec has always been the same, 2 x 2TB Hitachi drives, plus a boot drive of 500GB ( which I did not include in the spec, sorry)

The post here relates to the testing of the 2 x 2TB Hitachi drives, both are exactly the same, bought at the same time.

The only difference is the amount of data on them. One is 85% full, the other 40%.

Both report back no errors, whilst Seagate's Sea Tools reported errors and aborted, due to too many, on one of them, that prompted me to test them using Disk Properties Tools.

It seems that this Tools only test the unused area. I need someone to confirm this one way or the other.

Thanks.

I can't confirm that because I don't know.
