I was so happy when I tested ZAR and paid for my version right way, but I do still need help.

There is my story:

My Raid disks (24X200GB in 2 arrays) crashed last Friday, I even restarted the system a few times after it, I am very sure all data should be fine.

After I tested many tools (by viewing an ASCII file)
I decided to purchase ZAR, it did a very good job to recover my all Disks, so I used 2 disks (1 from each array) to reinstall the system.

After System up running, I tried to attach my SQL server data file (the date and size seems right). But I got an error that my SQL server cant read the file!!!

After many tries and read many posts on-line, I realized that my data file not recovered correctly, I then test some other ZAR recover binary files, such as image files gif/png, and some zipped files, such as zip/rar, now I realized many files actually didn't restored correctly.

I cant view many image files, cant unzip my compressed files...

I was running on a window 2000 advanced server (32bit), and saved to a window 2008 server (64bit), I then even tested to save to save system window 2000 server 932bit, the image files still cant be open.

As I read from rick7878 "Image header corrupt after recover" thread, I believe that my files have not restored correctly.

Please HELP, and save me!


:confused:

1. What type of the array(s)? 24x 200GB disks in 2 arrays, so that's
two arrays 12x 200GB, was that RAID5, RAID0, or 0+1?

2. Do not reuse the other disks from the arrays.

I believe that I have setup as Raid0
so 2 Arrays

Array1: 2X200GB
Array2: 2X200GB

When I tried to recovery it, I didn't set recovery for Raid, I used each Disk indiviually and recover the RAW filesystem.

Now I can NOT recover as Raid, since I thought i restored the data, and reformat 2 Disks (1 from each array).

The problem I believe is that:

The restored file header wrong or something corrupted, my data should be perfectly fine.

Can I restore my Raid Disk as a single disk?

what means:

2. Do not reuse the other disks from the arrays.

You cannot recover parts of the RAID as a single volume. For a RAID 0, you need all RAID member disks to recover the data from the array.

On top of that, if you write something onto the array members, this reduces chances of recovery.

Unfortunately we can help you with that. I have just did a refund on your order.
