:Are you trying to tell me that my is just sitting around waiting to

:and as I said above, it has been up for a week or so with no problems.
:Do you suggest I do more than what I have done?  

	You're certainly running the risk of having the same problem
if you only did a 'Zero' of that partition. I've found that the best
(or at least easiest) way to check the partition after Zeroing is to
go ahead and do a Format from AmigaDOS. This will read and write each
block on the partition and pretty much assure you that you don't have
a grown error waiting to bite you. If format hangs or aborts somewhere
on the partition, it's an indication that you should go ahead and
backup the whole drive then do a low level format with bad block mapping
turned on.
	If your problem is termination/cabling related, the errors will,
in most cases, be recoverable. Just click on 'Retry' when you see an
error. The risk you run there is during a write, some corrupted data
during a read usually doesn't hurt worse than a crash, corrupted data
during a write will leave you with something on the drive that you don't
want. :-{

:Thanks again for listing to my problems.....
