Ok, I had an external 200gb usb drive that suddenly decided that it was "unallocated" in XP's disk management snapin. I installed Disk Director based on good reviews of recovery from such a situation. The install went fine, I told it not to install the OS boot manager. I rebooted as instructed, and can no longer get into windows. Safe mode hangs on agp440.sys, the command console gives a BSOD Stop 0x0000007b. I used Winternals ERD commander and can get into the disk, all files are still there, and the disk passed chkdsk /r with no errors. But still can't boot it. I have to use something like ERD as its an NTFS partition, on a Promise Raid5 array controller. The array diagnostics also checked out fine. When I was using the ERD commander, the event viewer had multiple warnings about "driver detected a problem with drive controller blah blah" and they started at the same time I installed Disk Director. Is there some way to get rid of this thing so I can get the machine booted back up, at least into safe mode? I REALLY don't want to reinstall everything again.
