RAID restore
I have 5 hard drives and know that they were part of RAID array. Are there any tools which could analyze them and find out the correct RAID configuration?

... the free trial download will analyze them and show you what it CAN recover; but to actually recover them you will need to buy a license.
If the five drives were on a hardware RAID controller, then the RAID configuration is most likely written to the discs themselves - it depends on the controller. Do you know RAID controller the RAID set was created on?

I've tried RAID Reconstructor. Got XOR test all green, but Getdataback restored mostly trash. For example: when i open any txt file some part of it looks good, but the other part is just set of ASCII codes.

RAID Controller is HP NetRAID 1Si

Is the server hardware available to read the discs?
"... I've tried RAID Reconstructor. Got XOR test all green," ==> sounds good

No.

RAID Reconstructor writes image file, then you have to use GetDataBack to restore files from this image.

The NetRAID 1Si is an AMI MegaRAID controller - so if you have another server that has an AMI controller (easiest way to check is look for the Megaxx.sys driver for the RAID controller - also, AMI MegaRAID controllers use CTRL-M to access the BIOS during boot) you could plug the discs into it and it should be able to read the configuration off the disc. you should then have a readable array. Alternatively, if the array cannot read the disc configuration, then you can recreate the config non-destructively - the key is that you *must* know the order of the discs. If you get the discs musddled, then the array will be unreadable.

Thank you all.
My problem calls RTFM. RIDE Reconstructor determined disk order and after that I was able to recreate array in NetRAID 1Si BIOS

Sorry garycase, I wanted to split points, but don't know how.
I was fairly sure RAID Reconstructor would tell you what you needed to know about the order -- that's why I suggested just getting the demo download :-) Only the array was actually "trashed" would you need to buy the license and let it do the reconstruction.
