I can't seem to find if my bios only supports up to a certain harddrive space. I have googled around and even been to the dell website.....sighhhI am wanting to put a 320gb SATA drive in.
So, in spite of what DELL support says, you CAN have a 500 GB drive in your E 1705 ! http://en.community.dell.com/forums/p/19265826/19455128.aspx#194551284th post ^
