Hi, i have had to cases where SSD disks stops working and they look/are empty. One was with 2 120GB SSD disks in RAID where the Windows stops starting after some days and both disks was empty. One was a normal PC with one SSD disk and the same thing happend there, it was different SSD disks. Is there some incompatible SSD disk and controllers? On the machine with RAID i switch from onboard to Adaptec and then everything was ok. Isnt SSD disk 100% compatible with SATA standard? I have a third HP notebook that i used a SSD disk in and the machine dont find the SSD disk if it is a warm reset, i need to shutdown and restart to get i to work. All this machines works great with normal harddisks.
