The disk might be encrypted or locked. I forgot the technical term but if it is what you have then you can no longer use the disk if it remains unlocked. This lock is activated by the BIOS such that it can not be used in any other computer. It is possible and it has been reported that the BIOS can sometimes malfunction and lock you out from your drive. The only solution is to use a a commercial software that can unlock it. I have used it before but I no longer remember the name of the software. It is best to try searching Google. Most business laptops made by HP supports this feature. HTH, Holden
