Need advice on external hard drive
Now i'm not too familiar with these things, but to my understanding it is just a device that I hook into my macbook pro and it'll store all my MBP data into it, keeping it safe. Now I need advice one which one to buy? Really I just need a 80gb one, or even a 60gb if it exists. I just need to save my school work, my music and movies.
Also, once I buy one, how would I go about rebooting my computer? Do I do it like I usually would or is there a specific way to go about this if I have an external hard drive?
Thanks in advance!
they provide extra storage space.
you wouldnt store your OS on the external hard drive. you need to keep that on the internal drive, because the data transfer rate is much higher. if you put your OS on a USB or firewire drive your computer would be alot slower. (plus, you would have to buy the SL retail disc anyway, but we wont go there :P)
you could set up your external as a time machine backup: this saves all your data, OS,documents etc, everything! so if your hard drive fails, all your data is safely backed up.
you could however set it up as just extra storage for when you need it, just dragging music or movies over etc.
external drives are fairly cheap now, 250GB ones being under £50 here, so it should be about the same in the USA. why buy an 80gb one when you can get a dirt cheap
I am a Seagate fan, never had problems, some people on here prefer Western Digital. its really just personal preference/experience.
hope this helps somewhat.
If you are going to get a 60 or 80 GB external hard drive, I would not use it with Time Machine. Only back up your most important files that you want to save. I say this because Time Machine will eat up that whole hard drive half way through the back up. If you decide to get a bigger external hard drive you can use it with Time Machine.
If you have any more questions just post a thread.
There are those that suggest that reformatting your new drive before you use it is a good idea, and I'm one of them. It is easy to do. There are good instructions here:

Your external hard drive will show up as another hard drive icon on your desktop. You can backup your files to it just by dragging your Documents folder to its icon. If you want to backup everything on your computer's hard drive, though, it would be best to use backup software. This program is free and very popular:
Carbon Copy Cloner
Carbon Copy Cloner - Home
This one is $28, but some feel that it is easier to use:
Apple also offers its own backup software, which does a different type of backup:
Apple - Mac OS X - What is Mac OS X - Time Machine
We just had a thread recently on which drive to purchase:
Personally I recommend external hard drives from Other World Computing (OWC):
OWC Mercury Elite-AL Pro FireWire 800/400, eSATA + USB2 external Solutions up to 2.0TB - Plug & Play Quad Interface
...and I very much recommend *against* external drives from Seagate, Western Digital, LaCie and Iomega at this time. All of these companies have offered some very problematic drives of late.
You also have the option of installing the Mac OS on your new external drive (using your Mac OS installer disk), and then you can restart your Mac and boot from the external drive. The advantage of doing this is that you can use your external hard drive as your startup drive in case something happens to your internal hard drive and also for diagnostic and repair purposes.
Once the Mac OS is on the external drive, you can boot from it by either setting it as the startup drive in System Preferences --> Startup Disk, or by holding down the Option key while starting up or restarting.
I often use an external hard drive as a boot drive to test out and learn to use new versions of the Mac OS when they first come out. (As long as your external drive is connected via Firewire, performance is fine.) Using an external boot drive to run Disk Utility/Repair Disk, or, if you own it, Disk Warrior, is a quick and easy way to do maintenance.
