What problem with my PC would cause an Error 21 and all my music in WMP Library to be Deleted?

Question

My cousin asked me this question this morning...I suggested a device that was attached to her PC was removed unsafely, perhaps while data was being transferred to it. She said that she may have disconnected her cell phone unsafely while changing her mp3 ring-tone, but that wouldn't explain why music files were deleted from her PC would it?. Suggestions Please?

Answer 1

Window error code or runtime error?

Grub error Ubuntu Linux OS

Which one?
