RAID 1 fault “ Status Ready for Rebuild : Rebuild Percentage Complete 0%”

Our RAID 1 system partition failed on our Windows 2008 SBS (physical environment). We still have disc 1 running but the 2nd disc in the raid is a failure. To add to the complication, disc 1 has bad sectors but in a partition that is not required. HP have sent out a replacement for disc 2 but the RAID rebuild has failed due to bad sectors on disc 1.

We have backups from last night (backup exec) and a Windows backup from a week ago. We are at risk as we are running our Windows 2008 sbs on 1 hard drive with a bad sector. If anyone has any solutions, please help?

We have a spare in our RAID 5 (same server). Could I make the spare a standalone HD (not RAID), shut the server down and use Acronis (or similar imaging product) to image the good partitions on disc 1 to the standalone HD (the old spare from RAID 5). We have time over the weekend when people are not using the system.

Thanks

Hello,

I would strongly suggest you to shutdown the server properly and make a proper copy of the working disk (the one with bad sectors) on the HP replacement. After this i would boot the system on the fresh HP replacement and use the SPARE disk to get the RAID1 back.
I guess you could use Acronis this way.

What controller and firmware version? Later firmware on some allows it to skip bad sectors and continue with rebuilding, not optimal but better than nothing.

As far as creating another array plus logical disk on another single disk (or a mirror since you could use the one HP supplied as replacement as well) that's possible and you may even be able to "image" it using Windows software mirroring. Problem can be booting though since not all controllers / firmware versions let you pick which logical disk to boot from.

If you run a CHKDSK x:/r on the partition which has a bad sector then it will be marked as bad and no more used. You say you have recent backup - why not simply to rebuild the RAID with new drives and restore from the backup?

Hi,

All things considered I would go with noxcho's solution: use the new HP disk and your spare (both blank) and restore from backup. It's probably just as quick or quicker than rebuilding the RAID (if the CHKDSK /r works).

Problem fixed.  Here's what i did:

Ran a backup on Thursday night of C drive.   I waited until Friday and ran check disc on the good partitions. all came back ok.  Shut down the server.  Unplugged the RAID 1 with the HD with bad sectors.  I then inserted 2 new HD's with and created a fresh RAID 1.  I then plugged the bad sector drive into a spare SATA port and boot the server with Paragon Disk Manager 14 Business.  I then imaged the good partitions from the old RAID to the new RAID.  All worked ok after a few hours.    restarted and everything came back up

Its a small world we live in, in the tech world.  When i phone paragon to buy their software, i spoke to technical support who recognized this post and asked if i created this EE post.  Thank you Musa for your help on the software!
