I'm trying to restore a Firebird 1.0 database on an NT4 sp5 server. The
volume I'm restoring to has 20.5G free. About halfway thru the restore of
a tables data, the process aborts with this message in the log:

gbak: ERROR: I/O error for file "F:\IB\DELPERF\RESTOR~1\DELPERF.GDB"
gbak: ERROR: Error while trying to write to file
gbak: ERROR: unknown Win32 error 1450
gbak: ERROR: gds_$send failed
gbak: Exiting before completion due to errors


This was a locally invoked restore, not using service manager.

Any help appreciated,

Bob M..
