As far as I can say it went into 0 LBA while my PC booting. A month ago, when this happened, the RAID-BIOS said failed and when I deactivated the RAID-controller BIOS said "HDD S.M.A.R.T. CAPABILITY: NONE". Unfortunately my next action was not to look into the drive configuration of the Setup Utility, I first tried a few other thinks (different controller, different cables, different HDD-PCB) - all without sucess before I saw, that the drive is still recognized, but with all drive parameters set as 0 and without any capacity. EDIT: Thanks for your help, but neither m0,1,1,0,0,0,0,22 nor m0,1,1,2,2,0,0,22 are working, the same error as described in Post 65 appears.
