Hi, SRS-
I had a Sony MP3 player that was about the size and shape of a USB flash drive. It was supposed to be able to record, but I scrambled the drive's programming before I got a chance to try the recording function. Staples replaced the player, but I upgraded in the process of replacement, to a player that did not record.
I, too, wonder how well the other player would have done on recording.
