NetBSD 1.1 i386 bad144 confusion

Post by John DiMar » Thu, 21 Dec 1995 04:00:00



Having discovered a couple of bad sectors on the (IDE) hard disk I'm using,
I tried to remap them using "bad144 -a wd0 NNN NNN".  That seemed to
work, and "bad144 wd0" lists the bad sectors I've specified, but they're
still apparently being used by the filesystem.  Any ideas?  

Please send responses via email.  I'll be happy to post a summary of the
responses to this newsgroup.

Regards,

John

I promised to post a summary of the emailed responses I got.  Here is the
promised summary:

Only one person responded. He claimed that an IDE drive should be able to
forward bad-sectors when the drive is zeroed.  He suggested

        dd if=/dev/zero of=/dev/yourdiskd

I tried that, to no effect.

I ended up solving the problem by digging up a DOS-based hard drive utility,
and remapping the bad sectors using that.
