PC hardware: External hard Drive not recognized

External hard Drive not recognized

I know this is an old problem and I have been looking at various threads but am still not sure what if anything can be done. I currently have a generic computer with Intel Pentium 4A, 2400MHz, and 1024 MB (DDR SDRAM) OS is XP/sp3. It has 3 internal hard drives and also 4 external hard drives attached via USB
A few months ago I goofed and bought a SATA WD hard Drive which won’t work in any of my computers since they are older and have ATA (or IEDE) connections. I thought about trying to sell it on EBay since it was never used but then decided to purchase an external USB enclosure that would house a SATA drive. When I plugged this in I received a message (lower right hand corner) that new hardware had been detected and was ready to be used. But when I went to “My Computer” all of my other drives were listed but not this one. This one does show up in device manager as (WDC WD16 00ys-01SHB1 USB Device and says that it is working properly. So then, I went to Western Digital’s website and downloaded drivers for this hard drive which came zipped in a “package with drivers for 4 different drives. I unzipped for my SATA hard drive and it showed WD1600YS as an application. double clicked on this and I ended up in DOS (black screen with white letters" as follows:
WDDST057 Version 1.08
Update Drive

Nothing happens no matter what keys are pressed except when I click on the cancel X, then I get the following: “Windows cannot end this program. It may need more time to compete an operation, etc.” I don’t know if this is a driver problem or something else. I tried this on another computer with the same results. I also have a software program called Driver Detective that tells me that my computer has the necessary drivers for this hard drive. Or is this problem related to the fact that this is a SATA drive; I wouldn’t thinks so since it is going through a USB connection. Can’t check this hard drive out on any of my computers since none of them are set up for SATA.
