Silly Question!: How does an external HDD work exactly?

post #1 of 8
Thread Starter 
I'm curious as to how an external hdd works exactly.. Is it just something you plug in then theres just an alotted amount of space? Do you format it? Does it work together w/ your internal hdd? I'm looking to get one as my 80gb is squeeked down to 11.4gb open

its basically just a normal hard drive, except it is external. You can carry it around and stuff, some of them allow you to turn it on/off. Most connect to your computer through USB. Others have ports for firewire and eSATA. You will view it as a separate drive on you computer.

External HDD's simply show up as an extra disc drive in My Computer. You should format them the first time you use them.

An external hard drive simply put is an internal hard drive inside a case. Works exactly the same as an internal one, you can run Windows on one if you really wanted to but it'll lag a bit lot.

External hard drives are just regular hard drives in an external enclosure... the power is provided by a 120VAC->5VDC/12VDC adapter and the connection to the CPU is provided by a PCB that converts the IDE or SATA signal to USB/firewire/esata

The computer reads it as just another hard drive and uses it as such

^ as stated above by all others it works just the same.

Also if your mobo supports it the Esata drives are 6X faster than the USB 2.0 drives.

I am using the seagate free agent 500 gig right now and the prices are really coming down these days

I have 3 IDE drives and one enclousure and when I do major backups I just swap em all in and out. It's pretty easy.
