A dear friend of mine has been having a myriad of technical problems lately. This is just the latest one. I couldn't find exactly which forum to post this under, so I do  hope I'm not breaking some horrible rule. Please tell me if that is the case.

The other day she dropped her external hard drive and has since been complaining that while her music folder's status bar says it has all of her files, she can not see them. I had her search for hidden files, however that was not the problem. Her view options are set to display hidden files. The files have disappeared, but the folder size remains unchanged and the files are supposedly still there. I will enclose a screen capture below.

Has anyone ever seen such an error? And if so, do you know how, or even if, it can be resolved? Any information will be greatly appreciated.
