SOS!! URGENT HELP NEEDED!! my company's harddisk just died ... IDE cant detect it at all and after plug it into a external harddisk casing (IDE to USB), it still wont work or the PC didnt detect it at all!!

All this started when i backup my WD content into the Samsung so i can format the WD ... the backup content was about 20GB which i copied it into the Samsung's D drive, after formating the WD, the nxt thing was to transfer all the Samsung backup content back to WD .... with the Samsung acting as the master and WD as the slave.

Halfway during the transfer, the PC(Samsung = master) hang .... after waiting for so long and still no respond, i reset it and the nxt thing i know is that the Samsung wont boot up anymore nor the BIOS can detect it at all.

Is there anyway i can still retreive back the Samsung content even if it means sending back to the factory as its still under warranty i think? The content innit is so very important i belive it will cost me my job HELP!!
