Problems getting a second hard drive fully functional.
I have added a 160G hbd to my system. [root@pacman mnt]# fdisk /dev/hdb Command (m for help): p Disk /dev/hdb: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdb1 * 1 13 104391 83 Linux /dev/hdb2 14 19457 156183930 83 Linux --------------------- As /dev/hdb2 it has 777 privileges.

It is a very bad idea and not necessary at all for the device node to have world-writable permissions. Keep it at 600 or 660 (whatever your other disk devices have).

It says riht here:
[root@pacman mnt]# mkdir -m 777 /mnt/HDB2/PICTURES mkdir: cannot create directory `/mnt/HDB2/PICTURES': Read-only file system
The filesystem is mounted read-only. If you didn't mount it yourself read-only, the kernel could have changed it to read-only as a precautionary measure if errors were encountered on the filesystem. I suggest you unmount it and check for errors. Check for kernel errors on the device: dmesg|grep hdb Check the filesystem for errors: umount /dev/hdb2 fsck -f /dev/hdb2 If all is well, re-mounting it read-write: mount -o rw /dev/hdb2

doesnt matter

what is the `mount` output for that mount point ? is there anything interesting in the `dmesg` log ? -mike
Assuming that the drive has already been partioned with fdisk/cfdisk and formatted with whatever filesystem you choose to put on it, I try the following. when logged in as root: 1) does /etc/fstab properly show the filesystem type of hdb2? if it does not, I would specify the filesystem in the mount command. (mount -t type device dir) 2) Unmount the disk and reinstall the filesystem on the hard drive. Check for errors in the output. 3) check out hdparm, it might be worth a try.
