George's IOCell NAS lost connection after he upgraded to Windows 10. Leo says that what's important with a RAID NAS is having it built into the firmware. If the operating system itself is doing the reading with drivers, it's possible that the NAS company hasn't a driver for Windows 10. As such, Windows can't see it.
Spencer removed a hard drive from his RAID array and now he's having issues. Leo says some of the data needed from the reboot was on the missing hard drive. Can he just repartition the RAID? Leo says that the safest thing to do is copy off the data and then reinstall Windows. Then restore. That should copy the master boot record and get it all back to normal.
Kyle has a home theater PC loaded with media and backups on ten different hard drives that he swaps out. Leo calls that a JBOD (just a bunch of discs). But Kyle is having an issue with the drives getting errors while erasing and starting a new backup. Leo says that the flaw could also be in the backups themselves. It also changed to MBR (master boot record) and cut the drive storage in half. He also can't reformat it with GUID using Windows 10. Is there a special utility he can use? Leo says there is an MBR to GUID command in Windows.
Ivan has a 2 drive NAS that has files he needs, but the RAID 1 hard drive are reading as corrupted. He believes it is the corruption of one, synced to the other. Leo says that the hardware is probably fine, there's just corruption in the files themselves. But it could be a physical issue making it worth using SpinRite to repair it. However, if the corruption has spread, that points to a software error in the files, not the hardware itself.
Adam wants to create a new RAID 5 array, but his current RAID 1 system went belly up as he was converting to RAID 5. Can he get his data back? Leo says probably not through the RAID itself. He could take one drive out and try to recover, but Adam may have been too deep in the conversion process to restore the data. But the good news is, that he can take the drive out and plug it into the existing PC and see the data. If the data is mirrored, it should be easy to recover with a utility like Recuva. EaseUS also has a free drive recovery tool. He can probably use those to see the files.
Leo advises to buy multiple smaller hard drives over one extremely large hard drive. The bigger the size, the higher the error rate...which can be catastrophic in the worst case scenario. In any case, move away from old spinning drives to faster Solid-state Drives (SSD), where the cost per gigabyte is getting conveniently cheaper. You may have so much storage in the future that you could forget to discipline yourself on cleaning out files!
Rick bought a Drobo 2, and it's a bit flakier than his gen 1 Drobo. If it gets jostled, it has to reboot and rebuild. He's concerned that it's a single point of failure and he'll lose his data. Leo says that Drobos are a RAID (called Beyond Raid) where if one drive fails, it rebuilds form the other drives. So it's not really a single point of failure. But if all the drives go bad, then he's in a world of hurt.
John bought an SSD from Intel a few years ago, and it installed a RAID program in the BIOS of his computer. Now he can't get rid of it. What can he do? Leo says he should just ignore it. Most modern BIOS / EFI support RAID, but it doesn't really take up any usable room. It's just a firmware feature, so he can ignore it. He shouldn't mess with his BIOS anyway.
Jake swapped out his smaller SSD with a larger one on his computer. Leo says that Jake could just keep that drive as his software only drive and then use the larger drive for data. He could even combine multiple drives into a RAID for redundancy. He should keep in mind that using RAID 0 may be fast, but it's also less reliable because if one drive fails, it all fails. RAID 1 would give him data security by making multiple copies of the same data. RAID 5 is what is common now, and that offers the best of both worlds.
Brian wants to upgrade his MacBook Pro RAID drive and wants the fastest drive possible. Leo says that a Thunderbolt 3 external drive would be the fastest he can get for it. Leo recommends the Envoy Pro EX from OWC. It's also bus powered. But a 6TB drive is over $1,000, so it's not cheap.
