/mnt/hdc is a directory most likely it was created to be a mount point I'm guessing you have a device called /dev/hdc, and in your /etc/fstab file you have a line that activates that mount. You can always force it to mount by #mount /dev/hdc -t ext2 /mnt/hdc ext2 is the file system format you have on that drive, replace accordingly with ext3 reiserfs, xfs ntfs vat fat or whatever.

/dev/hdd would be the 4th IDE device on your mobo

I don't use wterm, but most terminals have a --geometry option like with Eterm I think i did Eterm -g x y h w x, 7 being where the top left of the window goes, and hw being hight and width obviously, these numberes are based off your resolution in xorg.conf so you could try something like exec wterm -g 100 100 400 400 and play with the numbers. You can do many cool things with the syntax of terms, you can have it auto run programs like top, or pine to check your mail.

Yeah as far as I know hda referes to the first physical harddrive, hda1 is the first partition on that harddrive. When i got my thinkpad it threw me off cause in the fstab i had to put /dev/sda in order to get my disks to mount. I think sda means SCSI device or something. But yeah, im guessing it's hdc on your dell because it's your 3rd disk.
