Data can be lost through a number of reasons. The drive (Floppy, hard disk or flash drive) can become faulty. In this case data recovery can be very expensive as only a specialized agency will be able to do this. Typical cost for a 40GB IDE hard disk is £700 to £800!

If the drive is still working normally but the data has been deleted by accident or formatted, the data can still be recovered by The Computer Garage for a lot, lot less..
