If you are buying for use in more than one computer get a self powered USB 3.5 inch drive. By self powered i mean one with its own power adapter. I usually just get a external kit and wait until WD or seagate drives go onsale for cheap. I bought a external kit for $35 and a WD 120 Gig drive for $29 after rebates last year. It has worked fine for me while i was using it. I let a friend borrow it and he somehow messed it up. I was storing 45 gigs of MP3's on the drive. I have been trying different recovery software with no luck so far. Luckily i have most of the music also backed up to CD's. I really don't trust external drives for backup's now as they can fail too. Lately i've been burning backups to DVD's as the hold about 4.4 gigs each.

I'm now looking for a self powered 2.5 USB external kit as i was given a USB powered kit that did not work. I check the laptop drive in my desktop with an adapter and it works fine. I guess the USB port just doesn't have enough power for the HD. I know that USB ports are rated a 2.5 watts and the HD is rated at 2.2 watts, but it just don't seem to work because while i was checking with a meter the laptop drive took 4.3 watts to start up. So im looking for a external powered kit.

if your getting an external hard drive it has absoulutly nothing to do with your motherboard or inner computer components

all you have to do is make sure you have a USB slot (which every one does) and it will work fine

look for one that preferably has a cooling fan a large cache size and is 7200 RPM

also i think you can get SATA external harddrives so look for them

yes, that is normal. Te reason for the difference is that the HD makers use 1,000,000 as a Gig, and microsoft uses 1,024,000. Technically a kilobyte is 1024 bytes so microsoft uses it. Along with this is formatting puts small files on the drive taking up space. My 80 gig Hd partitioned into 2 partitions shows as 74.48 Gigs in windows.

The reason for the difference is while the manufacturer may use decimal values, your computer sees binary.

Don't worry about needing a fan in the external case if it's made from aluminium it will dissipate heat as efficiently (if not better) than a drive inside your PC (and it will be quieter without one). My alumimium external enclosure runs a 300Gb/7200rpm WD drive no problem.

To the poster who questioned the wisdom of having an external one as opposed to an internal one -- well if your PC is already running 2 hard drives and 2 optical drives with no spare bays left (as in my case), an external one is the only way to add another, plus it can easily be removed and hooked up between different computers if required.

not true ther are many otherways to add internal hard drives including

SATA hard drives which run on different channels (if your motherboard doesnt have SATA slots you can buy a SATA control card)

and you can also buy a IDE control card

all of them are still quicker than external even though they go through a PCI slot
