My old (HP Pavilion) computer's power supply died, and I just got a new Dell Inspiron 530 desktop with Vista Home Basic. The new computer has all SATA connections, so when I wanted to transfer the data from my old all-PATA PC to the new one, I got one of those USB-PATA adapters. My old slave drive transferred its data just fine, but when I try connecting my old master drive, it doesn't work. When I remove the jumper to set it to the slave position, it isn't detected. When I set the jumper to the cable-select position, the computer detects the drive for about a minute, and then the "Found New Hardware" icon in the system tray disappears for about 30 seconds and comes back for about a minute and continues back and forth but never settles, and the drive does not appear in My Computer. I assume the conflict is with the old master drive having XP installed on it, but I do not know for sure and have no idea how to resolve the problem. Any help would be much appreciated. Thanks.
