This was me being stupid and the data is by no means critical and is now a learning experience first, time saver second.
I set up a 100GB iSCSI target via the bare bone instructions in napp-it. It's a volume LU.
I then had my Windows 7 machine connect to the iSCSI target, formatted it to NTFS, and tested the performance of it with some large iso file transfers. I then unmapped the drive, reconnected to the target, and was forced to format to NTFS again.
It was then I realized the files I had transferred only existed on the iSCSI target. I threw a little fit and then went about my business. When I was cleaning up my experiment I noticed in this screen: http://imgur.com/1xlcu.jpg
That is my experimental target tank/iSCSI and it still has a lot of data in it.
Assuming my isos are still in this pool how would I go about recovering them?
While writing this I used GetDataBackup for NTFS from www.runtime.org. And while it found two previous NTFS partitions there was no data.
