I recently received a new SATA Western Digital Caviar HDD (WDC WD2500ks-00MJB0 as its labeled in the device managner). I try to move files from my other 2 hdd (both ide) that are sometimes a few 100 mbs- 1gbs in size, my computer either freezes or it claims my computer dropped my new hdd and cannot find it. Once i restart, it appears again. Sometimes if the time is right, it will let me transfer but most of the time it will give me problems. I set the jumper according to the directions. Does anyone know what the problem is?
