FreeBSD has some tools in this area (see, for example, badsect(8)), but they have largely atrophied. > I searched the archive for this subject, and i found that simple > answer that modern hard drives have > the so called spare sectors, and if they cant do these reallocations > transparently because they > ran out of those reserved sectors -> throw the drive into the trash. > But what abou using freebsd on older machines with hard drives that > dont support spare sectors? > Having a few bad sectors doesnt mean that a 4-5 Gb driver is useless > because one isnt able to mark those > few sectors. If the disk is multiple gigabytes, then it's unlikely to be old enough to lack spare sector support. IDE has been standard for a *long* time now, and from my experience, pretty much *every* IDE drive *ever* has come with block remapping turned on by default. See the FAQ entry on the subject: What do I do when I have bad blocks on my hard drive? http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/troubleshoot.html#AWRE _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
