I put together an external drive using a Vantec NexStar CX enclosure and a Seagate 250GB SATA laptop drive. When I try to transfer more than 1GB of data at a time, the transfer will reach 60-75% complete and then the drive will stop writing data, the drive still has power but the disks inside just stops spinning. The only way to get my system to unfreeze is to unplug the drive.

I have tried using a Y-cable to draw power from 2 usb ports, but still no luck. I also tried using a WD drive, same problem. I also tried a WD Passport with the same issues. The drives work fine when plugged into an internal SATA connection.

I have used laptop drives as external drives before, but they were IDE/PATA drives and did not have a problem when using a single usb port, is there something I missed when I switched to a SATA drive? The Seagate drive is SATA 3.0Gb/s and the WD drive is SATA 1.5Gb/s. My system specs are as follows:

Dell Dimension 2400
2.66 GHz Pentium 4
2GB DDR RAM
Antec Earthwatts 380 PSU
Windows XP Professional

Any help is much appreciated!

I would suspect the enclosure, I haven't used a Vantec. I have a Masscool (USB powered) that can handle both SATA and IDE without problems

I assumed it was the enclosure as well, but I tried using an off the shelf WD Passport and the result was the same. I will try to get a hold of another enclosure, but I suspect the problem is on the computer side rather than the enclosure side. I also tried different combination off all of my USB ports with no luck there either.

Next time you use it and it quits, open Device Manager and click on the +'s By the USB controllers and look for yellow exclamation points
