Dear list,
after an incorrect power-off of my FreeBSD system, it does not boot =20
any more, BTX stops even before showing the cute beastie menu. =20
Starting the machine by other means, I found that the hard-drive is =20
installed on has bad sectors. I am looking for advices on how to =20
recover from this, if possible.
Basically the question is: shall I discard my hard-drive with bad-=20
sectors, or can I continue using it?
The Linux system I use to diagnose this says:
hdb: media error (bad sector): status=3D0x51 { DriveReady =20
SeekComplete Error }
hdb: media error (bad sector): error=3D0x30 { LastFailedSense=3D0x03 =
}
...
Buffer I/O error on device hdb, logical block 1663200
etc.
Since I use computers (1992) these are my first bad sectors :) (on =20
hard drives, taking floppies into account is no fun!). I hence have =20
several questions:
-- is it possible to let these sectors?
-- to which extents a hard-drive with bad sectors is usable?
-- while the apparition of these bad sectors coincide with an =20
incorrect power-off, are the two events related? The machine suffered =20=
plenty improper power-offs (or many), in the last years and did not =20
react so badly!
--=20
Thank you in advance for your advices,
Micha=EBl=
