ok, ive been browsing through the site looking for the solution to my problem for 2 days, and while ive come apon quite a bit of usefull info, none of it was 2 helpful. so in any case heres my probelm: i had an 120 GB western digital drive in my old computer, and figured id slap it on my new computer. its installed and the jumper setting is on slave, but it refuses to work. it shows up in the device manager, but when i go to the drive manager its not there. i dont know if this makes a differance but my master hardrive is on a serial ATA cable while the slave hard drive is on a parallel ATA cable. Any one have any ideas?
