Mary added a second hard drive and it won't spin up. Leo says it's likely that her power supply isn't rated to drive two spinning hard drives. She could replace the power supply first, or try an SSD, as they take up less power. If those two don't solve the issue, then she's looking at a motherboard issue, but that's unlikely.
Mark says that iTunes' user interface is horrible, and with iTunes 11, he can't get rid of a podcast. When he deletes it, iTunes reloads it! Leo says that other people report that it's deleting their music! So it's very manic. Mark says that iTunes won't load the playlists onto an iPad Nano because it deletes the media in the playlist. Leo says that is a known bug and it baffles Leo as to why Apple hasn't fixed that bug.
Micheline is moving from a Windows 7 laptop to a MacBook. Leo says that she'll love it if she does. Leo says that Macs have a high hardware standard and are well made. They also have better support. She wants the 15", but should she get the 256GB or 512GB SSD? Leo says to look on her Windows laptop and see how much space she's using now. That will give her a good idea of what she will need. Leo says that 256GB will be plenty, though. How about a refurbished model? Leo says only buy it from Apple.
Luiz has a hard drive that Windows can't read and it wants to reformat it. Leo says chances are that it was formatted with Apple's file system, rather than Windows file system. Leo recommends copying the files off of it using a Mac and then reformat the hard drive to FAT. Then copy it back. The Windows machine will be able to read it then.
Another option is to just buy a second hard drive that is already preformatted in FAT and then just copy them over from the other hard drive with the Mac. Then he'll have two copies, one being a backup. It'll then be a simple drag and drop.
Moe's computer running Windows 7 keeps shutting down on him. Leo says that with the age of Moe's computer, the hard drive is getting unreliable. It's time to backup his hard drive and then swap it out for a new one and reinstall Windows. It may be enough just to reinstall Windows, though. Leo does this every year as "spring cleaning." It keeps it more reliable. So he should try that first. He should backup his Documents and Settings folder to get his data. Then he can format that old hard drive and reinstall Windows.
Bob is having problems with his computer becoming unresponsive. It suddenly freezes up until he reboots it. Leo says that it may not be crashing for freezing at all. It may be an unresponsive mouse or keyboard. If the clock continues ticking, then it hasn't crashed. But if the clock is stuck, then the processor has halted. Even then, the processor may just be busy and he may just have to wait. He'll want to be sure it's really halted, though. If he reboots the computer in the middle of reindexing the hard drive, it could corrupt his drive.
Bill's hard drives keep disappearing from his computer. After he reboots, it'll say "fixing disk," and will be there for about 10 minutes before it disappears again. His SSD boot drive works fine, though. Leo says there are a lot of things it could be including hardware and cabling. He should go and look to see how its setup in BIOS. It should be something wrong with AHCI or a driver issue. Since he built the computer himself, there's no one he can call for help. Then again, the support from the major companies isn't helpful anyway.
Sam says it's time to get a new computer, and wants to know if he can bring along his old hard drive and put it in. His hard drive is pretty new, so can he swap one hard drive out and plug another in and start it up and get working? Leo says that would be nice, but it doesn't work that way. The Windows OS will look for the motherboards and chipsets and if it doesn't find that, it will have issues.
AJ opened up a laptop he hadn't used in awhile and all of his music and pictures were corrupted. A popup actually said the disk couldn't be read, and must be formatted. He tried to recover it. Why did it become corrupt? Leo says that hard drives die, and that's why you need a 3-2-1 backup strategy. 3 copies, on two different formats, with one off site.
