Would WinXP SP3 have problems with trying to use a USB/IDE cable connected external hard drive that used to be an old internal hard that is now being used as an external hard drive now; as I had no problems using a different newer external hard drive via USB, but when I tried to use this older internal/external hard drive connected by a USB/IDE cable with its own power supply it said that it detected it, but there may be problems getting it to work, and before I installed SP3 I was able to get it to work fine? Tried USB 1.0 and 2.0 ports, tried changing jumper settings, enabled all USB settings in Bios, even tried another computer; but the results were the same unfortunately. Already have 2 hard drives on 1 IDE cable and a zip drive on 1 IDE cable via IDE PCI Card and 2 disk drives on an IDE cable and a floppy drive on its own floppy cable and everything functions normally. Thank you.

It might not be right but is the drive setted as master slave or cable select, try putting it on cable select and see if it will work then, if not you may have to install a driver for it

Tried all of the jumper settings including cable select and installing drivers and it said the most up to date drivers were already installed. Same results on completely different computer with WinXP and SP3 installed, but a USB external hard drive works perfectly.

put the hdd into the internal ide inside the computer and reboot the computer and see if it works, if not see if it shows up in the bios, if not it will be a problem with you hdd, and if it does, try use a different ide converter and see if that was the problem.

Computer detects HDD via IDE cable and using another USB/IDE cable has the same results.

it may be your power, try plugging the power in via internal, and connect the usb/ide into the hdd and see if it comes up then
