Eva has a MacBook and it's running out of storage and she doesn't know why. Leo says to get the program Disc Inventory X. it will show what's using space in color coded sectors and whether she can safely delete it.
Dave wants to know if his old RAID hard drives can be read by his computer. Leo says it depends. If mirrored, maybe. They're identical. But maybe not. He shouldn't make any assumptions. Dave should copy the data off it and then he can take each of them and put them in their own enclosed drives, or use a new array like Synology. Synology also does a disk check periodically to keep it healthy. When he puts them in, they'll check the hard drives as they are building the raid.
Victor has an external drive which shows up as a drive, but Windows doesn't read it. Leo says to right click on the start button and select "Disk Management." It may be that the drive isn't formatted or partitioned properly.
Dave has a laptop with two hard drives with various ages. When is it a good time to replace the old drive? Leo says that hard drives fail over time. Google says that they will fail a lot at first, and then then to zero the first few years, and then about 8% a year after that. So if you're drive has been running that long, it may be one of the well put together ones. Hard drives are cheap so just keep your data backed up. Use it until it fails and when it does, your data's already backed up and ready for the new hard drive. Spinning drives also tend to fail gradually.
Tom says it takes over a day for his computer to boot up. Leo says it sounds like the startup process in the hard drive is damaged. If he can take the hard drive out and put it into a new computer, like Tom did, then perhaps it's a cable or power supply issue. Tom should try booting from the USB key and see if it takes the same amount of time. If that works, then clearly there's a driver or software issue causing it to boot up slowly.
Roger is having issues with his SSD. It's slowing down and takes a long time to access his data. Leo says the drive is only a year old and the computer a few years old, but there can be a drive failure, even in new SSDs. It's time to replace it. He could try running an OS from a USB key and see what happens. If he doesn't have a similar issue, that clearly shows the hard drive has a problem.
Terri's computer is crashing multiple times and trying to reboot. Leo says it could be a myriad of issues including a flakey hard drive. That's the most likely culprit. It could also be a bad memory chip that is corrupted and causing it to load and stall. Maybe the stick has worked its way lose.
The problem is, if she brings it in, it'll get wiped and sometimes they can make it worse. She can try and run a recovery with Windows. She can also download Windows 10, put it on a USB key, and then select "Repair" when she runs the recovery. Then backup her data immediately.
Scott wants to know if he can take the hard drive out of an old computer and then put it into a new one. Leo says yes, but he should only use it as a data drive. He could probably put it in an external USB enclosure so he can plug it in when he needs to. He could install it as a secondary hard drive as well. If he wants to use software from that hard drive, that's a lot more problematic due to registry issues. He may be able to dual boot from the older driver, but the device drivers won't work. So he'll have to work around that and use a boot manager.
Martinio can't see his external hard drive on his computer when he boots up. What software can he use to fix it? Leo says first he'll have to be able to see the drive to fix it. If he can't see it, then there's a hardware issue. It's a very expensive proposition to get the data off. DriveSavers will be able to do it, but it's very expensive.
Jennifer gets a boot error when she turns on her computer. Leo says that it's likely that her hard drive has died. Leo says the good news is that hard drives are cheap to replace and really easy to install. Also, since Jennifer had upgraded to Windows 10, all she needs to do is download and install Windows 10 with the media creation tool and a thumb drive. A solid state drive would speed things up too. She should make sure to get one with the same kind of connector. It could be SATA or IDE, so she should bring the bad hard drive with her. This is why backing up is such a blessing.
