Hi Everybody,
I got a server with Promise FastTrak S150 SX4 controller with 4 160GB disks in RAID5 array (3+1). All the disks are good, I make a DD image and recreate a Virtual RAID in R-Studio. All the parameters are OK, disk order, strip size: 64K, block order: left asynchronous, file system: NTFS. I can see the partition but when i open it there is only empty root and metafiles. I start scan for files and found everything but damaged. Only files and pictures below 64K are OK everything else is messed up.
In attachment is a print screen from R-Studio.
Now I'm looking in HEX to verify disk order with FILE0.
Any suggestion where is problem?

>RAID5 array (3+1)
Does it mean 1 drive is spare?

>strip size: 64K
Are you sure with this parametre?

Yes, I copy all the parameters from controllers setup. And 3+1 was noted there and that 1 should be a hot spare but all disks are part part of array. I try to remove one and work with 3 disks, use a missing disk option always lost the NTFS partition and get junk after scanning.
My opinion is that this RAID5 was 3+1 and someone recreate RAID with all 4 disks.

It sounds like the data is there it just got shifted and until you are able to figure out the shift int the data will not be usable. this seems to be a common issue with the newer raid controllers these days.
