Do (as root):
Code:
mkdir /mnt/drive_d
mount /dev/hda3 /mnt/drive_d
You should now be able to access the drive that you call D under /mnt/drive_d.
If you wan to load this on boot, enter (as root):
Code:
cp /etc/fstab /etc/fstab.bak
echo '/dev/hda3 /mnt/drive_d ext3 defaults 1 1' >> /etc/fstab
Please take this as friendly advice, but if you keep thinking in D drives and C drives, than Slackware is gonna give you a rough time. Slackware is said to be the most Unix like of all Linux distro's. It needs you to think Unix, so rather than drives you have filesystems and mount points.
Slackware is a great distro, and a perfect tool for learning the inner workings of a Linux environment, as well as building a customized system. It is very flexible and powerful, as well as stable and fast. But sure as I'm a sinner, it looks nothing like Windows in how you operate it.
