Hi, have a windows server hosted on vmware ESXi 4. One of the drives is showing errors. When running a chkdsk on restart it finds bad sectors and tries to repair but fails half way through. Would cloning the server within vmware fix this? Or will i need to create a new disk and backup\restore the information onto it

You have Windows running as a guest OS on ESXi 4. Where are your drives showing errors? In Windows? If so what kind of disk is it and how is it attached, e.g. is the disk virtual or direct access? If it's direct access you're likely having physical hardware failure and will need to move to a different disk.

Hi,

they are windows errors. VSS stopped working on the drive so i restarted the server and found that it went into chkdsk mode. After 20 mins of finding various errors it aborted and booted back into windows. The drive is still showing but obviously some data has issues. They are virtual disks on an iscsi san.

You had a VSS issue, rebooted with the disk marked dirty and thus chkdsk ran and various errors were found. Could you check your event log and post some of them? When you say chkdsk aborted how exactly did it abort? Did you stop it, or did it finish on its own?

If you edit settings on your VM what type of disk and controller are you using?

VSS errors are 7001 and 12305. There doesn't appear any errors relating to the chkdsk that run during boot up.. The chkdsk aborted on its own...cannot recall the error but it wasn't descriptive. Prior to aborting it was finding errors on various sectors. Using thick disks with LSI Logic SAS controller.

What text is listed for 7001? Did you make any recent changes to your disk configuration? In Disk Management do your volumes show up as healthy? How much space is free on your disks?

No changes have been made to the disk config. Disks show as healthy in disk management. Free space is >25% on all drives.

Please run mountvol from cmd and paste in the results. I want to make sure the VolumGUIDs match.
