That all files don't play on all devices. Consumers (which you won't be once you understand this nugget) expect the devices to just work. The reality is that MP3 files can only be encoded in specific bitrates for most players. I don't teach encoding, but you can learn about this on the internet.

Hi everyone
I was too careful with my new digital dictation machine/mp3 player today as I was plugging the device into the computer's USB drive. (Sometimes problems do occur when one is too careful) I was using an extremely light hand and thus didn't apply enough force when plugging it in so the device oscillated between "connected" and "not connected" repeatedly for a while, which is theoretically equivalent to repeatedly plugging the device in and out without using the "safely remove hardware" in a short space of time. The question is: would this damage the hardware of the mp3 player? I know data can be lost in this manner but I don't really mind that (since it's a new device and there is no data), my concern is whether or not the hardware is damaged. The instruction manual of the device does actually say that removing the device from the computer without using the "safely remove hardware" function might damage the hardware.
Afterwards the player seems to function ok when running music (except for very infrequent imperfections in the sound) but when I tried to download music files onto the device and in about 2/3 of the instances the copying didn't work. Is this because the device has already been damaged?
Thanks
