"Product: Toshiba 640gb usb 2.0 portable external hard drive (rocket red) new"

Is that what you plugged in?
If so.....

I searched with:
Toshiba 640gb usb 2.0 portable external hard drive (rocket red) new

and I got an exact "hit" for it on the Newegg web site.

It appears to be a 2.5" external drive, it comes with one USB cable with one USB connector on each end, it does not come with a power adapter that plugs into it's case, and it comes already formatted FAT32, according to the user reviews on the Newegg site.

(If it isn't already formatted, it won't show up in My Computer or Windows Explorer, but it WILL show up in Device Manager and in Disk Management - in that case you must partition and format it in Disk Management.)

I assume you plugged in the cable that came with this external drive into a USB port, then you were prompted to insert a disk in drive F.

1. The external drive must be plugged into a USB port that can supply enough current (amperage).

A 2.5" external drive normally gets all it's required power from the USB port it is plugged into (or from two USB ports - some 2.5" drives come with 2 cables or a Y cable so you can connect to 2 USB ports on the computer end if you need to). A single USB port you have it plugged into must be able to supply the full max USB spec 500 ma of current. The external drive enclosure's circuits and the hard drive inside the external enclosure will not be recognized properly if the single USB port cannot supply enough current.
If you are plugging this into a laptop computer, the external drive may only be recognized properly if it is plugged into a USB port that is physically built into the computer's base.
It may not be recognized properly if the USB port you have it plugged into is a port in a USB hub of the type that plugs into one directly connected USB port, often even if it's a "powered" hub that has an external power adapter and that's plugged to hub, or if it is a front port on a desktop case, or in some cases, if it is a port in a plate at the back of a desktop case that is in a slot space and is wired to a header on the mboard.
If you're plugging it into a desktop computer, it should be, at the very least, recognized properly when it it is plugged into any port in the main I/O area on the back of the case up high where most of the ports are.
If you have it plugged into a PCMCIA (PCCard) USB 2.0 adapter card, or an ExpressCard USB 2.0 adapter card, that plugs into a slot on your laptop, the external drive may not be recognized properly unless it isthe ONLY thing plugged into a port on that adapter.

2. What is drive F?
If it's your CD or DVD drive, if Windows was loaded from a regular Windows CD or DVD, if you have never connected an external drive before, you MAY need to insert your Windows CD or DVD into the F drive and specify the \i386 folder on it so Windows can copy something to the hard drive that allows it to recognize an external drive automatically.
.....

For some el-cheapo laptops, even the USB ports built into the base of the laptop cannot supply the full required 500ma, and in that case the external drive probably won't be properly recognized. In that case you need to either:
- buy a USB Y cable for the external case that has two USB connectors on the computer end and plug in both,
- or if the external case has a jack for it, you need to buy an external power adapter (AC to 5v DC usually, that can supply the specified current) and plug it into the external case,
- or you need to buy a PCMCIA (PCCard) USB 2.0 adapter card, or an ExpressCard USB 2.0 adapter card, that plugs into a slot on your laptop, and plug the external drive into that, BUT the external drive may not be recognized properly unless it is the ONLY thing plugged into a port on that adapter, unless the adapter has a jack you can plug an external power adapter into and you get one and plug it into that.
