I have a client’s machine, where he turned on the nvidia raid controller, configured two raptors as stripe and installed windows. ALL AOK.
He then re-connected his 200G sata Data drive (previously configured into 3 partitions) into this PC, he then booted and choose initialize disk as dynamic, then did a convert to basic disk. It was only then that he called me and asked "help where is all my data gone".
I asked him unplug the raptor drives, disable the raid controller and boot with an XP disk and see what the 200G showed as during a mock XP install, and it showed as 130gig un-partitioned space.
I am unsure what to advise him next to do, I was thinking he should format it and then run file recovery software, but am hoping there is a simpler quick fix.
I would have expected disk management to offer a “import foreign media” option, but he assures me it just went to the initialize disk process.
