Raid0 recovery / was functional before...

[Gabort]

Hi!

I moved my striped array of two 160GB Matrox disks from my old computer. On that machine, the array was functioning well, with no problems, but it was not recognized when I plugged the SATA disks into my new machine. (sadly the old one must have a real problem, since I can't re-install anything on it because it freezes before the OS would become operational - so copying is not an option from there.

ZAR 8.2 seems to recognize it, I opted for a scan, and I do get a list afterwards.

Clicking "Next" after the list appears results in a blank window with only the keys to the volume diagram showing, but no details. Pressing "Back" has no effect. I suspect the process under the UI crashes, I had to kill it manually. Needless to say, it takes a bit of time to complete the scan, and I am on my third attempt now if we take the trial version into account

Any suggestions? Should I be saving an image file from the context menu available in the "list"? And what image file am I going to get? Will I be able to move the data off the disk in a readable format somehow?

Thanks for reading, please send me some advice. It does not seem from this forum, as if many people have been using the software for Raid0, and I suspect there might be a bug here.

Regards,

Gábor

OK, same thing happened yet again.

I waited for the scan to complete, and got this: (click to enlarge)


Then, I tried right-click>Save Image and got a 0KB long file as a result.

Then I double-clicked the supposadly Netware volume (same result as pressing Next) and got to this: (click to enlarge)


The sad thing is, Back button will not do anything. I need an answer please.

Oh, and the Exit button only pops up the confirmation dialog, but does not actually cause the program to exit. Very dead, if you ask me, yet strangely, the program seems to be idle.



I have included precess explorer information in the attached .txt file.

I need the following:
1. How many volumes was originally on the array? What filesystems were on that volume?
2. Please ZIP the complete log file (C:\Program Files\ZAR\logfile.txt) and email to development@z-a-recovery.com

Hi Alexey!

I just sent you the log file, even zipped, its 6MB...

There was only one volume, with an NTFS file system. I used it to speed things up for realtime video manipulation.

I wouldn't bet aggressively on a 6MB attachment being delivered, so I attached the beginning and the end of the 65MB log. I suspect this is the interesting part.

The original array was the Windows software RAID, correct?

Regardless of this, proceed as follows:

1. Delete the log file, or rename to something else. This way you will start with a small log file.
2. Run ZAR. When prompted for a recovery mode, select "Recover data from a simple volume".
3. When prompted to select a physical disk, right click in the list, pick "Define RAID manually".
4. From the list of available drives, select ID 0101, click "Add", then select ID 0103 and click "Add" again (note - ordering matters; this assumes you did not plug additional disks, i.e. the IDs are still the same).
5. You will now have two disks listed in "Array members". Enter "Start, Size" as 63, 312581745 for both.
6. Select "Array type" as RAID0.
7. Verify "Stripe size" is set to 128 sectors. Adjust if required.
8. Click OK to close the window.
9. Now refer to the log file (do not close ZAR). You should have exactly this entry near the end of the log file (followed by "RAID ID transform" entry and drive list). Verify.

-------------------------------------
Volume information for ID ...
Origin             : Reconstructed RAID
Partition type     : Unknown
Capacity           : 298 GB
Number of sectors  : 625163490
RAID type          : RAID0 (Stripe set)
Stripe size        : 128
Rotation parameters: 0 / 0
Member 00          : 312581745 sectors at LBA 63 on device 0101
Member 01          : 312581745 sectors at LBA 63 on device 0103

Continue as follows.

1. The device ID 0400 (Virtual RAID #0) will appear in the list.
2. Select it, click "Next". The partition table should appear, listing one single device (Novell Netware volume).
3. Disregard it, right click in the list and pick "Define the volume manually".
4. In the volume definition dialog appeared, select "There was only one volume", click OK.
5. The new entry will appear in the list - ID 04000300, Unknown filesystem type.
6. Select it, click Next to start recovery.
7. Report the results back.

Thanks Alexey!

It is now working with these settings. I am copying files, and they are not corrupt.

Thanks for quick and efficient support.
