Hey, my new disc seems to cause a bit of a problem for me. No data has
been lost the logs give me disturbing information. It is an old ATA 33
disc and as I understand it should use DMA mode 2 transfers. It seems to
me that the disc is recognized by the system as and Ultra DMA mode 2
disc and that it then downgrades to PIO mode? I also seem to have some
physical sector errors.  Is there a tool/trick to =93quaratine=94 these
sectors?  And can I set the transfer mode =93hard=94, to say DMA mode 2?
