Slow Copy speed

I do Copy file(12GB-backup PC) from HDD PC to external USB HDD (iOmega 1TB) - speed is about 980kbytes/s, but when I do Copy same file from iOmega to HDD PC - sped is about 49000kbytes/s. I do copy with Total Commander. Why is different copy speed?

Wow that is quite slow indeed. Wondering if all your drivers are up to date...and if not for some reason it is assuming that IOmega device is a USB 1.1 device or not....argh I dunno this is a difficult one.

NO, iOmega is USB 2. And all chanals are Ultra DMA Mode 5 or 4 enable.
