Things like SD cards are seen as disk drives formatted with the MS-DOS FAT file system, and can have the same problems as real disks with file system corruption. In particular, you can get "lost clusters". The cluster is the smallest unit of space on the drive readable/writable in one operation. It's possible for clusters to be marked as in use, but not actually owned by any files. This will mightily confuse the OS and programs that use the files, and can lead to the sort of behavior you are seeing.

CHKDSK can analyze the drive and find and allocate lost clusters to files, which can then be examined and (usually) deleted, restoring the file system to sanity.

Thanks, Dennis. I'll give a try. As of right now, I'm still trying to download books to the MS Pro card via the reader and it is an excruciatingly slow process.
