Re: Harddisk problem

Hi,

Got a brand new Samsung 250 GB IDE harddisk, added it to my home PC running
FreeBSD 5.3, created FreeBSD filesystem there.  I have been using it for
several months, keeping relatively large (5-10 GB) home video files there,
and it has been working fine.

But now suddenly got the following problem:

I'm not yet very familiar with harddisks, filesystems, and FreeBSD, but is
there anything else i could try to make the disk usable again, or is it
somehow physically damaged?

Taavi,
I'm not an expert but the smartmontools port may help, I am installing it now to keep me informed of hdd status. I can remember reading in the documentation about repairing drives.
http://smartmontools.sourceforge.net/

http://www.linuxjournal.com/article/6983

I hope this helps in some way,

Ivan
