Hi guys. im faced with a tricky problem here. i got a 500 gb wd caviar hdd and a 160 gb segate drive in my system.all was well until yesterday when i started the system all went wrong i use win 7 after i entered my pass at logon screen everything wwent dead slow icons generated slowly drives opened slowly pictures videos opened but with stuttwr and lag. wen i started speedfan and and did a short test on my 500gb hddit showed read error and there was no activity on my wd hdd. surprisingly the other segate hdd was fine. when i copied vids from the wd hdd to segate hdd it copied fine and played well without stutter or lag. i checked all cables its working normally. so what should i do is my hdd dying. any suggestions would be appreciated
