This computer doesn't recognize a "blank disk" - does this mean a new hard drive that you haven't installed an OS on or by blank disk do you mean a blank CD or DVD?
Are the undetected external drives detected on other computers?
Strange but true, NONE of my old CP/M or DOS or Win 3.x or Win NT through NT4 detected external drives either unless the drives were SCSI and I had installed a SCSI host adapter in the PC. (HINT - the Operating System in use is important)
Assuming you are using Win 2000 Pro or newer for your OS what happens if you boot into a different user account?
My dell laptop is not detecting external drives or blank disc. What could be going on ?
