We can classify the ways that hard disk can breakdown in two: software and hardware. With the first I'm talking about the lost of data due to virus or accidental erasure. In these cases, if it's possible retrieve the information, it is often so cheap because only we have to use the appropriate software. Instead, the errors of hardware or physics are very expensive of repair, because are needed tools and specialized installations and only if the information that contains is enough valuable, can worth pay for it. Read all about of "Repair the hardware of a hard disk"

Hz is not equal to Mbps
How many times have you hear, told or wrote the expression X megs of bandwidth. I'm sure that a lot of times, because the continued use of this phrase, have been converted in the regular way of talking of all the people and is totally incorrect. Something seemed happens when say that we weight 154 pounds, being the pound a unit of mass and not of weight. We must say: "I weight 70 kiloponds" or "I weight 154 pounds-force". Follow reading if you want to know why the case of the megs of bandwidth, also is incorrect. Surprise yourself with the rest of "The Megs of bandwidth doesn't exists"
