It would'nt take forever but yes, normally the bigger your hard drive is, the longer it takes to defrag. It also depends on how bad the hard drive is in need of the defrag.
Check disc and defrag
No! In fact, it's best that you're NOT online while doing a defrag. Anytime defrag hits a part of a hard drive where the information is changing, defrag restarts doing that portion of the drive. While on the Internet, your PC is constantly sending and receiving files and changing what's on the hard drive. Your defrag will take a lot longer.
Simpletech produce portable external hard drives. These range from small USB sticks, to larger external hard drives. Simpletech also produces mini versions of the portable hard drives
With Windows XP if any programs (even those running in the background) or the screensaver interrupts the defrag, it will restart/hang. In Vista, the defrag is designed to defrag at a certain schedule in low priorty in the background. In order to defrag and use the PC at the same time you need to use an automatic defragmenter like Diskeeper which runs in the background in invisitasking mode and defrags silently without conflicting with other programs.
Some of the larger Asus towers can hold up to 10 hard drives if needed.
Modern hard drives connect to the hard drive using a SATA cable. Older ones use a larger, slower IDE cable.
Back when solid-state hard drives were first invented the initial cost was higher per GB or even MB on older hard drives. Now however new technology has enabled the cheaper building of flop circuits, making it a whole lot cheaper and therefore more ethical to build larger capacity hard drives.
The top four brands of 1TB Hard Drives are amongst others Western Digital hard drives, Seagate hard drives, Toshiba hard drives, and Hitachi hard drives.
There are many portable external hard drives which would fit into most standard size pockets.
Do a Defrag. and a Disc clean-up
External hard drives are available at all office, electronics and computer stores. The main choice to make is between compact units using notebook drives, and larger devices using desktop drives. The larger ones are cheaper and more reliable, but the compact ones are much more convenient.
Depends on the capacity of the drive. I have a 128Gb flash drive, which is obviously larger than 64Gb. You also get solid state (hard drives) which are essentially large flash drives which are larger than that
