Is the Ext drive on a network?? What was the drive letter assigned to the ext drive?? Can you go to a command prompt and access the ext drive ie dir m: ?? Since the audio program can still access the files makes it sound like a network share and theaudio program is accessing via share name not drive letter ie \\server\folder. How is the drive attached to server?? Since it appears that the drive still shows up in explorer you may want see if you can see the files in a command prompt if nothing shows up then try attrib *.* and see if any files are listed. If you can see the files from DOS then make a copy to another drive and run a check disk on it from my computer.

Sounds like your master file table (or FAT, if not NTFS) got corrupted during the power failure. If you haven't already, try running a scandisk/checkdisk on that drive to see if it fixes the problem. Also, have you verified the status of the array since the power failure? It's possible that some damage was done to the RAID array and you may need to rebuild it or at least run a "verify with autofix" on the array itself - this is usually done through utilities supplied by the mfr. of the RAID card. Hope this helps!

It sounds like a typical external SCSI problem to me. When the power was lost both devices shut off and then when it came back on the server probably just didn't synch properly with the Cart drive.

I'd do a graceful shutdown and power off of both devices and try restaring first the SCSI device and then power up the server when the SCSI device is done initializing itself.

The scandisk idea is also quite good and I'd do that as well.

Sounds like you're at a radio station.
