At the end of a session cleaning up a user's PC from programs no longer used, I discovered that ntierh drive showed up in explorer and, on checking further, in Disk Management. That is, no drive letters at all in explorer and in Disk Manager as if they were not even in the machine.
I'm pretty sure that deleting the programs wouldn't have caused it; and the user says she hasn't occacsion to use them in months, so whatever happened could have been today or it could have been long ago.
I already went through the routine of shutting down the machine (Dell Dimension 4300 with XP, by the way), disconnecting the ribbon cable from each, powering on, powering off, reconnecting the cables, and powering on. Windows didn't see as new hardware and try to install them.
What, short of reinstalling Windows, is the procedure to get the drives back?
Thanks, Ron Hicks
