Jim wants to know why his computer can't read his USB thumb drive. Leo says it's probably formatted wrong. If he formats it NTFS, he should be able to read it.
Charlie wants to rip his CDs to a memory stick. Should he partition it since it's 128GB? Leo says why not just get a smaller one? Or, better yet, rip the CDs into higher quality. If he's going to do it, do it once. Charlie should rip the CDs into FLAC, which is a lossless format, and preserves 100% of the CD quality. MP3 doesn't do that, neither does AAC. FLAC is identical to CD quality. Use that for archival storage and then he can convert down from there to a USB drive.
Tom has a picture with the format .KQP from a Konica camera. How can he convert that? Leo says there's a great website for this at OpenWith.org. He can search by extension and get help on how to open it. It recommends XNView for this particular file, and they also have a converter. He should check out XnView.com.
Michele spent some time in the Microsoft Event viewer and she's seeing a lot of registry errors that she's worried about. Leo says that's perfectly normal. The event viewer is just a log of errors and it really doesn't mean anything. So she shouldn't fall for the scam that uses the event viewer to get her to buy something. If she wants to, she can clear it out.
