A friend of mine runs ESX and to store the VMs he uses Starwind on a Windows-server.
Recently he accidentally assigned the wrong local volume in Starwind. Instead of pointing to the disk with VMFS he pointed to a NTFS disk with 1 Tb of important data.
He started the ESX which found no storage - he run a rescan on iSCSI but found nothing.
He then noticed his mistake. Too bad the Windows-server no longer detected the disk. The NTFS-volume was gone and the disk looked like a raw unpartitioned blank disk.
He then send that disk via mail to me so that I have a look.
It really appeared to be blank.
I then used testdisk - see http://www.cgsecurity.org/wiki/TestDisk
It detected the disk as upartitioned raw disk of 1 Tb.
I run the "scan for lost partitions"
testdisk found the volume and offered to fix it.
Two minutes later everything was fine - data is back unharmed.
Maybe it helps someone ...
