Bill wants to know about the Zello walkie talkie app. How does it really work? Does it transmit over the air like a real walkie talkie? Leo says it doesn't broadcast, it uses your mobile phone data network to communicate. So you use data every time you use Zello. It's similar to VoIP in that regard. It's fun and handy, but it does eat through your data.
Don's dad left him an old Windows 98 computer and he has to get data off it. But the laptop won't boot up due to a hard drive issue. What can he do? Leo says a hard drive can wear out and it may be that the drive is dead. But it could also be that it simply won't boot up. It's just getting flakey with critical sectors, meaning that the data is still there. So Leo says to stop trying to boot it up. That'll only make it worse. Take the drive out and get an external drive case or a universal drive adapter and use it as a data drive. NewerTek makes a great one.
If you have an old computer that no longer will power on, you may be wondering how to transfer the data from the hard drive to a new system. Fortunately, this could be as easy as plugging in an external USB hard drive and just copying the files over. The USB Universal Drive Adapter from Newertech makes that possible.
If you need to transfer your data from an old phone to a new one, there are a few ways to do it. First of all, check to see if your data is already being synced to the cloud. Data such as email, contacts, and calendars are likely already stored with Google or Apple's iCloud. You can verify this by logging into your Google or Apple account from a web browser and checking to see if the data is there.
Tyler has a 20-year-old computer and he needs to get some data off the hard drive. He's having trouble finding a port to connect his video monitor to. He doesn't have VGA. Leo says he'll have to have a VGA port because that was the standard back then. If there's no VGA, then it could be a server. But he may be able to find an old video card to plug into it.
Leo recommends just getting a hard drive enclosure for it. He'll need an IDE model. Then he can connect it via USB to his current computer. That's far easier than trying to connect everything to it to see what's on it.
Peter upgraded his iPhone to the latest version of iOS 12, and ever since then, his text messages haven't been sending right away. Leo says the first thing to do is call his carrier. There are two ways messages get sent on an iPhone, however. It's either being sent with iMessage which uses his data, or as an SMS. He's only having this problem with the built-in Messages app, and it's with everyone. Leo thinks it has to do with his wireless carrier.
Mike wants to know what he needs to use his iPad on Wi-Fi. Leo says that any iPad will work on Wi-Fi. If he has LTE, however, he could use it anywhere. But for Wi-Fi, a regular iPad will work just fine. Since Mike is traveling internationally, Leo recommends also getting a MiFi card, which he can put a local SIM in for Wi-Fi. But since Mike is in the US Virgin Islands, international data roaming won't be an issue. Leo recommends getting an AT&T carrier version of the iPad. Leo likes the iPad Mini for traveling.
Paul wonders if it would be possible to build a hard drive that could hold all the information available in the world. Leo says that currently, we have hard drives large enough to hold all the information in the Library of Congress. But we really don't know how much information we really have in the world. We do know that by 2025, there will be 163 ZetaBytes (a trillion gigabytes). We're creating data at a rate of 16 trillion GB a year. The largest hard drive out there is 8,000 GB. So probably not. But that's what we have the cloud and the internet for.
Carl's wife is going to the Philippines soon and he wants to know the best way to stay in touch internationally. Leo says that the real answer is WiFi. She'll be able to make calls or even video conference via Skype, Facebook, or WhatsApp. If she uses WiFi, it won't cost her anything. She should just make sure to turn off data roaming on her phone. She can also use Google Maps and preload map data so that she's not using data while getting around.
Steve is in the process of digitizing everything and backing it up. Now he needs to consider backup options. Leo says the first thing he should do is make sure his data is encrypted. Windows 10 Pro offers BitLocker, which uses full disk encryption that unencrypts when he logs into his Windows account. He should be careful not to lose his password or certificates. He should back those up and keep them in a safe place.
