unable to mirror due to an I/O error

By nestora ·
I am trying to install Windows 2000 server. The process went fine until I tried to mirror the system volume. The system volume is a partition of 2GB HD. The Hard drive is a SCSI-160 36 GB IBM. When I ran the mirror, I got the following error when the mirror was 92% completed ==> "Operation aborted due to disk I/O error". When I checked the Event viewer I got the following errors:

dmio: Found a bad block on disk Harddisk0 at block number 3867762
dmio: Harddisk0 read error at block 3867726: status 0xc000009c
The device, \device\harddisk0\DR0, has a bad block.
dmio: Harddisk0 read error at block 3867711: status 0xc00009c
the device, \Device\Harddisk0\DR0, has a bad block.

After investigating the cause of these errors, I used the chkdsk /f /r and rebooted the server. Everything went OK after rebooting, but when I tried to establish the mirror the same problem appears. I did that a couple of times with the same outcome.

It is very important for us to be able to mirror the system partition, but we need to fix this problem first. Do you have any suggestions on this issue?. Is the problem caused by a bad block or is it caused by something else? Why did the chkdsk /f /r not fix it? How should I fix the problem so I can mirror the system drive?

From the errors seems that your hard drive has some bad blocks.
The mirror will not complete if the hard drive contains error (bad block).
The chkdsk cannot solve the problem, it just check for file not for the block. Maybe you should use anotherthird party program, such as norton utilities.
If the bad block still not beeing recovered, then the only way you have to replace the hard drive.

Chksdk may not fix problems that it does not see. I recommend, like the first poster, that you replace the hdd; you do not want your mirror (to be used in case of a failure), to be defective as well (especially when you need to use it).
