XP RAID 5 Missing Data after OS Crash

June 23, 2009 at 15:20:47
Specs: Windows XP, Athlon 3400+/1 GB
I installed and configured XP Software RAID 5 using the Hex edit techniques described elsewhere on this site. But my OS crashed and now I can't seem to recover my RAID array from my newly installed OS. The RAID 5 array is composed of 4 500 GB SATA drives, and my OS is on a separate IDE drive. This was all working fine for 2 years. After my OS crashed, I needed to reformat my IDE drive with the OS, and reinstall XP SP2 again. The 4 SATA drives now showed up as 4 Basic, unpartitioned disks in Disk manager. I reapplied the XP RAID Hex edits again on the new OS files, changed the disk type from Basic to dynamic for all 4 SATA disks, and now RAID 5 was now an option again for these drives. I right mouse clicked on one of the drives, choose RAID 5, and selected all 4 disk. I did not select to format the drive, and then clicked to proceed. The drives in the array showed as "Regenerating" for about 16 hours, and now show up as "Healthy" I thought I'd be all set at this point, but explorer lists the drive as unformatted, and has no data. Did I do something wrong? Is there a way for me to retreive my data at this point?

Look at the link below. There is an indication you can port the array to a different system so you may still be able to fix things.

Importing the array should have been your first step.

Since you reinitalized the array file recovery is now impossible.

Thanks Mr Hill.
That article was my bible for getting this configured in the first place, but as you say, they're an "indication" you can port the array, but no specifics regarding the steps. I rebuilt my OS on the exact same hardware, and the RAID 5 array didn't magically pop up. The steps I went thru seemed reasonable, but the results did not pan out. I'd really like to know what the steps are to "port" a windows RAID 5 array to a new OS installation on the same system. Anybody ever have to do that? Please help. I had almost a terabyte of family Pics and video on it. It is supposedly backed up via Mozy, but it'll take me a year to download or cost me 120 DVDs shipped to me. Ouch!

Google import foreign disk xp.

Though with your reg hack to raid5 does complicate things. I believe one blog I read awhile back had you do the regedit for raid5 then do the import of foreign disk.

you were doing well until you initialized the raid array.

You would never want to convert to basic as that wipes out all the information also.

Thanks Wanderer.
Import foriegn disk... dang. That's a bummer.
I looked and I couldn't find that. Sometimes success in life is all about knowing the right google search words. Ah well, the mozy restore seems to be coming along well enough so far. Thanks again.
