Unfortunately, the overwritten data is gone.

Your best bet is to recover the dead hard disk you removed, do you still have it?


So, If you need help, give a shout.

Did the RAID overwrite all sectors...is that the reason?

The backup drive is 500gb...the raid 1 is only 250gb with only about 4gb of usage (bare windows xp installation).

Yes, it overwirtes with a sector copy, there is NO fixing this.

it does a sector for sector duplication. that's why it takes so long.

Are the dead drive and the over written drive model duplicates?

No.

Initially there was 2 drives (in Raid 0).  What I did was I backed all the files completely onto backup HD..then formatted and re raided the 2 drives into Raid 1.  The two drives were 250gb WD, while the backup HD is a 500gb Hitachi.

So am I essentially SOL?

Actually no, you may be able to recover everything.

You can get the raid recovery software from runtime.org.
Buy it as a package with Get Data Back

setup a fresh hard disk of at least 500 gigs and setup windows on it along with Raid Recovery & Get Data Back.

Turn off nvraid.

Plug in the two 250 Gigabyte drives  to the  computer.

You can chose in the raid recovery software, the two drives that are striped members (don't initialize them in windows and don't set them in the system until windows is loaded and you have the recovery tool loaded.

boot the system, open the raid recovery software, chose the 2 drives.

image the two drives to a file on drive C. (destripe it to an image file)

Once it is de-striped to a file, you can disconnect the two 250 gig hard disks. (Shut down first)
then you can run get data back on your image file that you have on drive C.

This will get all of your data back.
99% chance of success.

Sorry, I did not understand the exact situation until your last message.

Thanks, I will try that.

However, let me add this:

Assume original two RAID drives are RAIDHD1, RAIDHD2 in Raid 0 setup.  I disconnected RAIDHD2 and replaced it with another hard drive RAIDHD3.  Then using NVRAID, I created a RAID1 (RAIDHD1, RAIDHD3) and formatted (quick) and installed WIndows XP on it.

So RAIDHD2 still exists (as part of original Raid 0) setup...while RAIDHD1 is now overwritten with Windows XP setup.  Will the runtime software still work?

if you formatted and installed winodws xp on it, you have damaged and wiped some of the data out beyond recovery.

It is iffy now you have added this complication. I'd give you a 75% chance of getting data for your efforts, however, I don't know how much of your data was destroyed by your installing windows on a failed rebuild.

If you had stopped before installing windows on the drives, you had a good chance of recovery.

Good luck with your attempt.
