how to reach data from failure hard disk

my PC suddenly turn into blue screen.
after i restart my pc, the monitor is blank
dell said that my hard disk got problem and simply gave me a new hard disk
however, i really need to reach and backup data from the old hard disk
i try to make it slave and open it in other pc
the pc can detect the slave hard disk but when i try to access it, i got a message said the disk is not accessible.
is there any way i can recover data from the hard disk?
