Hey all, i've installed windows 7 on my laptop successfully with no problems. now, i'm trying to install it on a desktop, but windows 7 does not recognize the seagate hard drive in either DOS installation mode, or windows 7 installation mode while in windows xp pro. it recognizes my western digital hard drive(drive C, but not my seagate barracuda ata IV(model # st380021a, which is drive F. when i remove my western digital hard drive and have only the seagate connected as the master, the computer automatically boots from the windows 7 dvd, but does not find any drives. i tried installing it from windows xp pro(my western digital, drive C:, has XP pro), but only drive C: (western digital) shows up, the seagate(drive F doesn't. here's the kicker; the seagate is working fine, because it shows up in 'my computer', shows up in disk management as 'healthy', i was able to copy files to and from the seagate. i did the "change drive letter and paths" for the seagate also, and still nothing. what could the problem possibly be? i tried looking for 'drivers' for the seagate hard drive, but they're nowhere to be found- since there's an option to look for drivers during windows 7 installation. also, the seagate does show up in the bios as well. i'm puzzled, any help would be appreciated. thanks in advance!
