Slow USB transfer speeds
Anyone know why the transfer speed from HD to USB is so slow? It took about 5 mins to move a 1GB file from my HD to a PSP.

Are you talking about an internal HDD or an external HDD?

I couldn't say. Perhaps your controller was recognized as 1.1 or something silly like that. I have not had any issues.

I guess you could say it is an external HD. I checked the device manager and it states Hi-Speed, which I assume means spec 2.0. I went back to my XP install on the same PC, and the same file took under a minute to transfer, but in W7, it takes about 5 minutes. The details say it's transfering around 3-4 MB/s which extremely slow for USB 2.0
