My computer has crashed and after diognostic says ERROR CODE : WHD16-09W my mate rcons the hard dive has gone bit of a pain a not backed bup , please help and ho can i retreive the data.
If the HDD has indeed failed and you never made a backup image, you are probably out of luck. There are services that have ways of moving the platter(s) to a different drive and recovering your data, but those services are quite expensive.
try unplugging the drive from the system and letting it sit for a few minutes. Sometimes reconnecting it will then let it run again for awhile.
