Hey all. I'm a newbie so please don't pounce on me for repeating a topic. I have read through similar ones here and on other sites and have gained no help or direction. Well, here goes. My problem is with a relatively old drive; a 20gb seagate. i removed it when cleaning the case and when i reconnected it, it could not be detected. The jumpers are correctly positioned and all cables are secure. In my cleaning I simply ran a hair dryer through the board and wiped the housings for the drive. I tested the system with a seagate 120gb and that is detected with no problems. the 20gb isn't detected by the bios or as a slave to the 120gb. There are no tell tale signs of a mechanical fault - no strange sounds or anything else out of the ordinary. my issue isn't so much replacing the drive(it is time 4 a system upgrade after all) as it is recovery of the past 3 weeks of work that has not been backed up! it would take me 3 weeks to get through it again. lol! please help guys!! i forgot to add, the drive is powering up normally. also, the system seems to take a long time to start up, almost as if it were trying to detect the drive.. but alas... still nothing..
