How to make an external hard drive
By now you have learned extensively of what an external hard drive can do for you, maybe it is the time to find out exactly how to make an external hard drive. You don't feel like engaging in such a daunting task you could simply buy an external hard drive and skip over the whole business. But that would not be very fun now wouldn't it. The main reason for which some one might want to make an external hard drive on its own is the fact that many times after upgrading the hard disk in their laptop many users find out that the old hard drive is rather useless because they can't use anymore as laptops can only one internal hard drive at a time. The solution of transforming the old hard disk into an external hard drive suddenly seems the best one. Now the laptop hard drives are using the 2.5 inch standard so when attempting to build an external hard drive of your own you must take this factor into account. The way to transform an old laptop hard drive into an external hard drive is pretty simple. You must purchase an external enclosure, fit the old hard drive in it and voila you have it. Now when purchasing you should be aware that prices range a lot depending on the way in which the hard drive will communicate with the motherboard. Of course the connection can be made through a serial or the parallel port, but this is really not recommended as the external hard drive obtained this way won't have any plug and play capabilities and the transfer rate will be rather low. More advanced solutions such as the ones using the Universal Serial Bus or Firewire are much better as they are true plug and play devices and have great transfer rates, Firewire more specifically can reach up to 400 megabits per second and trust me that's a lot. The reason for which someone might want to transform a PC hard drive into an external hard drive are quite different as a typical PC offers up to 3 slots for hard drives, if the computer itself uses a CDROM, which is usually enough. If someone transforms a PC hard drive into an external hard drive they probably need some extra mobility and the capabilities that plug and play devices offer. Although the motives differ, the way in which such an external hard drive is constructed is no different from the one containing a laptop hard drive. The procedures on how to make an external hard drive are just the same with the notable difference that PC internal hard drives have a 3.5 inch system. So to keep things simple these are the steps you must follow: find an appropriate enclosure, fit in the hard drive, plug it in the computer. Pretty simple, isn't it?
