I have a new disk drive (Toshiba MK538FB) and have been getting several media
errors. So for it has had about 10 in three weeks, one of which caused some
files to be lost. None of the media errors has occured twice on the same
block. Does that mean that 3.0 has marked those blocks as bad, the blocks
are borderline bad, or that my lightly used system hasn't tried to read
those blocks again?

What needs to be done about the Media errors? Please e-mail any suggestions or
comments. I have included the errors from /usr/adm/messages at the end.

Thanks,
