I just installed Mandrake 10 on a second hard disk and it says my other hard disk is read only and locked and I can't seem to unlock it. I tried right clicking on it to change permissions and tried doing some sort of chmod command at the prompt but it didn't do anything. How can I unlock my second hard disk so I can access it?

Try tampering with your bios, but save changes. If you have less than 5 drives than try getting your cmos settings to boot to your second hard drive as a primary. If that dosnt work cook up a lilo/gnome floppy.

What type of partitions are on the other dirive? NTFS, FAT32? S Doesn't sound like a BIOS problem.

It's NTFS, I have Windows XP on the other hard disk.

Redhat does not include NTFS support by default.
http://linux-ntfs.sourceforge.net/ ( AFAIK Read only )

For read / write (No actual experience)

Are you able to mount the NTFS partition? Post your /etc/fstab file.

Yeah I can mount the NTFS hard disk. I'm actually using Mandrake 10 Official and not Red Hat although I don't really know how much it matters seeing as Mandrake is based on Red Hat, or so I've heard at least. Here's my /etc/fstab file:

/dev/hda1 / ext3 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hda6 /home ext3 defaults 1 2
/dev/hdb2 /home/windows ntfs defaults 0 0
/dev/hdc /mnt/cdrom auto umask=0,user,iocharset=iso8859-1,codepage=850,noauto,ro,exec 0 0
/dev/hdd /mnt/cdrom2 auto umask=0,user,iocharset=iso8859-1,codepage=850,noauto,ro,exec 0 0
none /proc proc defaults 0 0
/dev/hda5 swap swap defaults 0 0

Sorry about that you did say you were running MDK. I confused myself since your distribution lists Redhat.

Anyway... replace defaults with umask=222 as an option for your fstab entry for /dev/hdb2. This will give you read permissions for all users.

Ok but I want read AND write permissions for everyone, what are the numbers for that? I forgot how to do that whole adding thing for yourself, other users and anyone and all that stuff

AFAIK included support for writing is still experimental. See the link I posted for captive for writing.

Are you refering to uid, gid options? Not necessary for everyone having permissions.
