Hi,

----------
From: 	Robert Chalmers
Subject: 	SCSI verify media? will it destroy the data?

Does anyone know if a SCSI AHA-1540C controllers, Verify Media command
will leave the disk intact, apart from relocated badtracks/sectors, or is
it a destructive scan?

I have a SCSI disk showing bad-sector errors, and I dont want to have to
do a complete rebuild if I can help it.
----------

With the 1542 the verify media command is destructive. The bios diagnostics notify you of this and give you a chance to back out. I assume the 1540 will behave in a similar fashion.

Regards ...
