On some hdd's there is an option on the jumper settings next to master and
slave. That for some reason, limits the size of the hdd. I don't know why
this option exists, but it does. Also, you never get 70GB out of a 70GB hdd.
Once again, i don't know why. It's just the way it is.

Lachlan

Hello,
We just installed and mounted a 2nd HDD(secondary ide channel) on a
Dedicated Server on FreeBSD 4.8 and look what it gives:
] df
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/ad0s1a 2015918 52114 1802532 3% /
/dev/ad0s1f 22479870 16924774 3756708 82% /usr
/dev/ad0s1e 4031950 73418 3635976 2% /var
procfs 4 4 0 100% /proc
/dev/ad2s1e 76958474 4 70801794 0% /drive2
] df -h

/dev/ad0s1b none swap sw 0 0
/dev/ad0s1a / ufs rw 1 1
/dev/ad0s1f /usr ufs rw 2 2
/dev/ad0s1e /var ufs rw 2 2
/dev/acd0c /cdrom cd9660 ro,noauto 0 0
proc /proc procfs rw 0 0
/dev/ad2s1e /drive2 ufs rw 2 2
The problem is that from 73GB (80gb hdd) it only sees free 68GB.
How can i check if it has bad sectors? A friend suggested me low-level
format but I never done that before under unix.
Also, do i need to be in single-user (I dont have physical access, only
remote root via ssh).
Thank you.
