I need to free download driver for qps 525

there is no driver for qps-525 because it was made for mac only not indows

If you happen to have the Que!Drive USB QPS-525, it will infact work in windows xp, however you require the assistance of a driver to support the conversion of ATA/IDE to USB. The solution I found to the problem came from a quick search on driverguide. And can be found at the following: http://download.driverguide.com/driver/QueXPCTX21+Drive+USB+Adapter/QPS/d236422.html

As for the out of place post as a solution asking if a hard drive will work in the enclosure, it should so long as you have the driver for the board that converts ATA/IDE to USB.
