Ok, so format does not lock out bad sectors, does DISKCOPY
(CLI or Workbench flavors) do ANY kind of verification on
the data that has been written?

I asked this question a couple of weeks ago and the only
response was a deafening silence on the net.

I have lost several files doing DISKCOPY to unformatted disks,
only to later find one or more I/O errors on the disk. After
running Disksalv I tried to format the bad floppy: no go.
I've had errors ranging from bad sector number to checksum error.
The disk was junk to start with, so why didn't DISKCOPY catch
the errors. It seems to me to be a fatal flaw if there is no
verification of the data written to the disk!

For those with racial bias :-) I've had 3 black (generic trash),
2 dark tan (bulk BASF), and 1 blue (do I dare say it?? sony) fail.
