I have a Laptop (Pentium IV) and i'm running XP. I recently bought a external hdd exclosure and put an old harddrive into it. When I connect it via USB, the computer immediately picks it up and installs the drivers. It appears under device manager and is fully functional according to device manager. But the device doesn't appear in "my computer". I tried assigning a drive letter with "administration tools", but the device doesn't appear there either! Should I try formatting it? And how should I do this, since I have a laptop and can't just plug it in on the motherboard. I heard about fdisk (don't know anything about it) , but how would I use this if the computer doesn't pick up the drive?! Please help me. I'm desperate.
