In early December I received a new 660mb SCSI to replace my 80MB RLL
Micropolis.

Until recently, I had terrible problems.  Powerpoint would not run, Windows
would not (re) install, Borland C++ V3.1 would not install.  I could, however,
boot from this drive.

After experimenting with different sizes of partitions I finally ran PCTOOLS
pattern tester - a program that writes various bit patterns to each sector.  I
did not see any errors.  I reformatted (low-level and DOS (high) level),
restored from the disk and have not been able to make it fail since.

I would guess that SCSI drives revector the bad blocks themselves and running
the pattern testing caused it (finally) to revector after installing and
reinstalling a lot of software many times.

It appears to me that there was a large chunk of bad blocks that have now been
revectored.  I am now confident that this is not a software or floppy
media problem.

Since the drive is still under the 90 day warrenty, should I return the drive
for another?  I'm worried that I used up all my replacement blocks already. Is
there a way to get a list of revectored blocks?

	    Thanks,
