The computer becomes terribly slow: it is a problem hard drive?

Have you ever turning on your computer(Dell inspiron 1440 battery) and see what it would take 10-15 minutes to even load Windows or other operating system? Have you ever start to receive the message "could not find the operating system.

Well, even worse, because if there is this really happened you are experiencing problems in one of the worst that can happen to a PC(with IBM/Lenovo Thinkpad x60 tablet battery), namely a hard disk failure, the event is particularly bad because in addition to a broken piece of hardware as vital the hard drive is a real risk of losing all data were stored inside. Sometimes you can recover data by simply connecting the external hard drive via a USB Charger to another computer(Toshiba PA3534U-1BRS) in this case had only affected some sectors of the disk that prevented a good start.

But the worst may happen that the failure is really a mechanical part of the disc, ie the head or the disk itself and then is forced to resort to one of those expensive data recovery service where physically dismantle the hard drive and make a clean room recovery and reconstruction of the data sector by sector.
