Hi all, First post here so please be nice. We have a Windows Server 2003 which is randomly giving a BSOD. I've looked through previous threads and seen similiar problems but would appreciate any second (3rd or 4th) opinions. I've analysed the minidumps and have received the following output; DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) ----------------- Unable to load image a320raid.sys, Win32 error 0n2 *** WARNING: Unable to verify timestamp for a320raid.sys CURRENT_IRQL: 8 FAULTING_IP: a320raid+d90e SYMBOL_NAME: a320raid+d90e FOLLOWUP_NAME: MachineOwner MODULE_NAME: a320raid IMAGE_NAME: a320raid.sys DEBUG_FLR_IMAGE_TIMESTAMP: 3f8f321a FAILURE_BUCKET_ID: 0xD1_a320raid+d90e BUCKET_ID: 0xD1_a320raid+d90e Followup: MachineOwner To me this looks like a RAID problem, specifically the Adaptec Raid Card driver? We have a C:\ which is a hardware raid (Adaptec RAID Controller) and a D:\ which is using Windows 2003 software RAID 5. After a crash I logged on to the server and noticed the d:\ was resynching. Any thoughts on where I should troubleshoot from here? cheers, Damien.
