That's no problem. Just at usrquota and grpqouta in the correct line in /etc/fstab.
Here is a part of my fstab entry:
LABEL=/ / ext2 usrquota,grpquota 1 1
LABEL=/boot /boot ext2 defaults 1 2
LABEL=/home /home ext2 defaults,usrquota,grpquota 1 2
The / partition is a little SCSI disk and the /home disk is a big IDE HDD.
Save the fstab and than go to the root of your second harddisk.
Mine is, as example /home. Here you must create two new files........

OK, here agein in the right order:
1. Login as root
2. Modify /etc/fstab: add usrquota,grpquota like the / partition
3. Go to the root of the partition you wish to enable quota, then create quota.user and quota.group by doing:
touch /partition/quota.user
touch /partition/quota.group
chmod 600 /partition/quota.user
chmod 600 /partition/quota.group
4. Then run the command: /sbin/quotacheck -avug to 'index' the second HDD for quota
5. Make a reboot to check the correct running at boot time
6. make a quota for a user and copy some files to the new HDD. If you can't write the data, you have reached the quota limit. Check this with the server-manager.
I use SME 5.1.2 a long time and made the change after installation. After the little problem with the warnquota, I got it work correct without problems since then.
Have a look at this for more information about quota:
