This is an excellent product that goes without comment. There is no surer support for safeguarding valuable data. Beware, however, because the hard drive is formatted in FAT32. This implies that you can not save files very large. Of course, the solution is to format the hard disk to NTFS. I suggest doing this when first. Windows XP / Vista / 7/8 formate NTFS, in less than 30 seconds. Cool, right?
