All hard drives are ATA .
The difference is SATA or PATA [IDE]
If it fit in the enclosure & hooked up it should work if it's going to & your desktop is providing enough power at the USB port.
Thanks for the response. That clarified the ATA/SATA difference for me.
It did fit well into the enclosure, but I am having trouble accessing the drive on my desktop computer. The power light on the enclosure does not stay on constantly, but it rather blinks on and off. I was able to access the drive once after I connected it, but my computer slowed down to a crawl and I could not access all folders and files on the drive. Eventually my computer froze, until I removed the drive from my USB port.
BTW, the enclosure does not have a power cord, it receives its power from the USB ports. It has two USB connectors, and I both, as the manual says that both may be necessary to get enough power.
I was thinking the mobo of my laptop was destroyed when I dropped it, but maybe its just the hard drive. Any suggestions or tips for troubleshooting the laptop?
