I have a iomega 2tb external hard drive which I store my movies on. I want to know if I swap the drive between my Mac and my pc without doing any damage
Answer
Yes and no.
As long as you dismount properly - Eject the drive (mac) or do a Safe disconnect (windows) there is no damage to move the drive between machines
However, whether the data can be read and written depends on the formatting of the drive.
If you are going to be using the drive exclusively with Windows, choose NTFS as the formatting type. (NTFS can be read but cannot be written to by Mac OSX).
If you are going to be using the drive exclusively with Mac, choose Mac OS Extended (HFS+) as the formatting type. If the drive is to boot an Intel Mac machine, go into Partition Options and choose GUID as the partition type. (HFS+ cannot be read or written by Windows)
If you are going to be using the drive between Mac and Windows machines, choose FAT-32 (MS-DOS in the Apple Disk Utility) as the formatting type. One option is to partition a hard drive in Mac OSX and format the first partition to HFS+, then the second partition to MS-DOS (FAT-32) for shared data. Note that Microsoft wants you to use NTFS and in Windows limits the formatting of FAT-32 drives to 32 GB. There is no limit on the OSX Disk Utility however, and larger volumes formatted FAT-32 with OSX will work on Windows machines. Note that the maximum individual file size under FAT-32 is 4 GB, so it may not work for movies.
Reformatting the drive will delete all the data

Linux on an External hard drive as a virtual PC.?
Joshua
This has slowly turned into a nightmare. I just want to put Ubuntu onto my 1TB drive, but:
1) the windows installer only lets it run as a "parallel session" inside of windows. so basically, as a program.
2) the disk image the "desktop version" download gave me is "not valid" according to windows disk burner.
I just want some clear freaking instructions on how to download and install a copy of Ubuntu onto an external hard drive, and actually have it boot...
I've worked on this for about 4 hours in a row as of now, and I just can't figure this out. I've tried just about everything! Help!
Answer
Try burning with isorecoder or nero.
Once you have the disk, boot form it, run the integrity checker to verify the CD is good, then boot into live mode to confirm comapitiblity with your hardware.
shutdown
Then crack open your case and disconnect the internal drive (this will prevent mistake in the installer) plug in the external and boot from the cd. Select use whole disk (assuming the external is the only hard drive connected, if not you'll have to use manual setup and specify the bootloader location on the MBR or the external drive)
finish the installation, reconnect the internal drive. Make sure the BIOS tries to boot from the USB bus before the hard drives. Then when you have the drive connected, you'll boot into grub and probaly linux, when it's disconnect it should boot straight into whatever you have in the internal hard disk.
