I have 2 HFS partitions on my 120GB disk.
The first 80GB HFS partition (named: MacOSX) is my start-up disk where Mac OS X 10.4.8 located.
The other 40GB HFS partition (named: Data) is for my data and music.
Everytime I log in as regular user, the 40GB HFS partition is mounted read-only (for regular user).

Anyone could help me how to mount my 40GB HFS partition as read-write for regular user.

Thanks in advance.

When you log in as admin, rightclick on partition, select "get info" at the bottom of this window you have user rights... make it read/write for all users

thx, i'll try it.
anyway, is there any solution for this using fstab.
What i've done is creating a folder named "Data" with permission set to 777 and then editing the /etc/fstab adding line says mounting to "Data" with option "rw".
(UUID='myUUIDdisk' /Data HFS rw,auto).
But it didn't work. Still that HFS partition is mouted read-only to "Regular User".

But anyway i'll try your suggestion. Thx.
