getting file onto usb flash drive


stupid newbie question, I'm sure, but . . .

I bought a few items from HDtracks because I was curious about trying high-quality digital downloads. My Marantz SACD player (8004) has a slot for a USB key. I converted the files to apple lossless encoding (one of the formats supported by the Marantz, according to its manual) and copied the files to a USB key by just dragging and dropping them. The player won't recognize the files, giving a message about incorrectly formatted media.

Then I tried using iTunes to copy the files. No more bad formatting messages, but the files still won't play. Any help will be appreciated.

I second the PC option, go back to HD Tracks and download the Media Monkey software(free) to convert the files using the sync option, then you can drag the the HD track files to your flash drive!
I see in the manual that the only lossless format it supports via usb media drive is Linear PCM 16 bit WAV files. Don't see anything about Apple lossless support via this interface.
Windows media lossless comes in at about 1/2 the original size on my pc and outputs through the USB. I have used it on 3 pc's with Vista, 7 and XP pro.
