SBS2003 server partition corrupt

Hello,

After a power outage, one of our client SBS 2003 servers was forced to restart. This server has 3 partitions on a single RAID 5 spindle. The C: partition is working, as the server boots up. However, the E: partition (which contains all the client's data and their Exchange installation) is showing up as blank.

Before I start poking around too much, I would like to get some advice. I am looking at the backups right now, but wondering if there is a better solution than restoring from backup.

Thanks!

Jeff

If you look at the raid controller what is the state of the raid 5 array? Is it healthy? Is the partition showing with a drive letter or without. If without assign it the correct drive letter. Other that try another reboot so see if that helps (gotta love windows). If the data still does not come back you are looking at recover from backup.

RAID controller says it's in good shape. Partition shows drive letter E:. Reboot a couple times does nothing (I sure was hopeful, though!). Attempting to restore data from it, and installing a replacement server on the side, just in case. Running VirtualLab on the server to see if it can recover any data from the partition with the broken format. Might have to turn this into a server migration!

Good thing it's only Saturday. You could have them up by Monday morning. The upside of doing that is you get a clean install. Also personally I don't like to run any server OS on raid 5. It's better to run the OS on raid 1. I don't have a problem with data on raid 5. Anyway let me know if you have any more questions.

So your partition says it needs reformat if you want to access it - right?

Noxcho: Yes.

Here's an update: I am running VirtualLab on the server and it's recovering data from the partition. If all goes well (so far it's recovered the most important data files and Exchange databases) I am going to reformat the partition in question and then move the recovered data back to the newly formatted partition. The external hard drive backups are a couple days old (of course...), but it looks like Virtual Lab is going to have the most up-to-date data available.

I have also setup a replacement server with SBS 2008 (the client has a license with their original Open Value SBS subscription), run FSTW and Windows Easy Transfer on each workstation, exported all Outlook data to PST, in case I decide to migrate them to a new server while we're at it.

When you get a chance you should purchase the swing migration documentation from www.sbsmigration.com its well worth the money, will save you time and heart ache. At the end you dont have to touch the workstations, they just connect.

Instead of reformatting this partition - delete it - then use Undelete Partition such as from Paragon Drive Backup 10 Server trial www.drive-backup.com or look if your backup software has such feature.
It can restore the partition in the state it was before the corruption.
If it fails then you can go your way of reformat.

noxcho: the partition looks OK (it sees it's theE: drive, it's the right size, etc.), but the formatting is corrupt. Do you know if the software cares whether or not it's partition or format corruption? It might be worth trying, but it's Sunday afternoon here, so I'm looking to get a solution (migration, data recovery, etc.) in place as quickly as possible! The VirtualLab software restored a ton of data, but I don't know if it got everything, since I don't use it day-to-day. I was going to try to avoid blowing away the partition or reformat until I find out if they have all the data they need. We have a local data recovery company in town that is standing by, but at this point the VirtualLab software can see the data, access the data, and let me copy it (which I let it do all night and most of the morning today).

Download the software I mentioned and install it on this server. Run it and in middle of its window find Volume Explorer. Try to browse via it the E: drive. Does it open it?

The Paragon software might be good for creating and managing partitions, but according to one of their techs, it's not meant for partition repair/recovery. Since we got the data recovered that we need, and sent it to a separate drive, we might just wipe the original problem partition, reformat, and move the data back to the original since it's on an otherwise healthy RAID 5 spindle.

Thanks for the feedback!

The Volume Explorer tool inside of this Paragon utility browses unformatted partitions and lets recovering data from them.
Sometimes the cause of unformatted partition issue could be corrupted boot sector. But NTFS partitions always store copy of BC at the end of partition. And one can save and restore this sector over the corrupted one. This also can be done via Paragon - view/edit sectors.

That's interesting. Which product is it? I wonder why the Paragon tech didn't mention anything about that.

noxchoCommented:
Any of their trial version can do that. Could be that you dealt with a tech representative who works not so long there.
For example Drive Backup 10 Server trial has this feature.
Note, if the problem is with file system then it is definitely useless for you. Only file level data recovery is a solution then.

Our temporary solution was to put in a new IDE hard drive and temporarily relocate the E: drive to it. We moved the recovered data from the corrupt partition using VirtualLab's software. Restarted the server with the 'new' E: partition and everything has been running. It's a temporary fix, but the server is staying in production.

This is the solution we came up with.
