I received mine yesterday and had a problem similar to yours. When transfering music to the player using Teracopy (I prefer to use this utility for CRC check up and guarantee a proper transfer), it reported that one of the already copied file was modified by an external application. What first came up to me is that this one was also hacked to appear to have more memory that it really has; I proceeded to open it up to confirm memory part number. Well, it is not hacked.

Now that I am using my job pc everything seams to be ok.

According to my experience using external hard drives is that, they tend to demand higher current from the USB power supply -that's why they have two USB plugs. I know that my home's PC doesn't comply the USb power supply standard, it's an assembled unbranded PC and that my transfers between both -pc and external hard drive- are more susceptible to errors due this issue. This might be happening with this player and despite being USB Ver 1.0 (yes, slowwww transfers!!) it might be demanding too much power. My job's PC source better USB power and hence the transfer is more stable. I'll have to double check at home and use the USB extension that my external hard drive comes with to do it (using both USB plugs).

Have you tried to transfer from other PC?
