I don't know if this is a stupid question, but I haven't found any info about this particular question:
I have two hard drives, the first one, primary master with dual booting windoze xp and slackware, and the
second on the primary slave with a couple of fat32 partitions where I simply store data. Now whenever I'm in Linux
and logged in as a regular user, I cannot save, copy, move, or create any kind of files to the fat32 partitions; I would have to become root in order to save or create files to the vfat or fat32 partition. I also tried doing chmod +777 but nothing changes, I cannot change the drwxr-xr-x and give other users write permissions. Any ideas?

I have found that the following entry into /etc/fstab works, allowing any user to mount and R/W to the windows drives:

/dev/hda1 /C_dos vfat rw,user,noauto 0 0

Hope it works for you. -mk
