I can't seem to get this to work.... I have two HDDs... A.) ST380012A - Original B.) ST3160021A - New I'm trying to set A as the master, and B as the slave. I got the jumpers all correct, in the boot diagnostic both devices are recognized correctly as master and slave. However...one of two things happens. Windows gets stuck on the boot load screen. Doesn't freeze, the bar keeps moving...and moving and moving and thats it...just stays there. This happens when I configure the jumpers as master and slave specified, as opposed to cable select. When the jumpers are set to cable select, I'm able to get into the Windows install on the master just fine...but can't browse any files or anything on the slave, B. I have gone to My Computer > Manage...nothing there. I have tried Add New Hardware...which picks up the new Disk Drive...but computer is running slow slow at this point for some reason, it either freezes or just...poops. Something I just noticed while writing this thread. On the boot diagnostic, the following message appears. So far only noticed when jumpers are not configured for cable select. IDE Channel 1 no 80 conductor cable installed On a side note...Drive A is the working main HDD for this machine with the Windows XP install. Drive B is one a friend gave me to see if I can get some files off of it.
