I am having an awful problem with my Promise FastTrak S150 SX4 RAID controller. Have used this card in PC for years. Had RAID-5 4x 250GB disks formated drive NTFS working fine. Woke up this morning, new problem "FastTrak does not detect proper interrupts" - computer hangs, will not boot. There was lightning last night, but I had my power supply switched to OFF in the back, but still plugged in to the wall. I moved the card to a second PC (but same power supply) and same issue. If no drives attached, computer recognizes card fine and boots fine, and Local PAM can see the card and the channel and all 4 channels. However with 1, 2, 3, or 4 drives plugged in to the SATA data lines, the same problem occurs "FastTrak does not detect proper interrupts" - cant boot past this. P.S. I have disabled all COM ports, and the Parralel port, and disabled USB!
