Attached HDD to Gembird SATA-PCI controller, Partition gone.

[noban]

Hi!
Legend: workstation had 2 SATA drives 500Gb & 320Gb, I've bought additional 2x500Gb hdd's and STA-3 Gembird SATA PCI host adapter. Unfortunately instead of connecting 2 new HDDs I've connected one new 500Gb hdd and one 320 Gb hdd with lots of info Once I've booted, I've gone to RAID contrioller setup and noticed that there are 320Gb listed, then I've reattached drives and removed SATA-3 PCI HOST Adapter with its attached HDDs at all. Surprisingly 320 HDD wasn't detected, I've checked in Vista's Computer Storage Management panel and found that this HDD is fuly unpartitioned.

What next actions should be done?

As I understand it would be nice firstly to clone this 320 Gb hdd if yes then wchi soft should be used?
After that partition should be restored somehow - which soft should be used?

Regards,

Partition Find and Mount did found lost NTFS partition. As well it was successfully mounted and explorer is pointin to G: and all files on it are accessable, (can see JPG's, play mp3,... etc) but when I'm trying to copy these files to other disk (as I don't know how to restore partition and want to make backup, afterwards at least I can just format HDD) I've get error:

Location is not available
G:\ Referes to a location that is unavailable. It could be on hard drive on this computer, or on a network. Check to make sure disk is propperly inserted. .... (some other similar text)

As well "cd G:" is not working.

How can I copy files? Or how partition can be restored?
