Months ago I had problems with external USB drives disappearing from my system. Often times, rebooting fixed it... for a while at least. But on one occasion, I couldn't get a drive to show up, so I wanted to switch USB ports. I tried to use "Safely remove hardware", but it wouldn't eject the drive. I got frustrated and unplugged it anyway.
Plugging it back in did not cause it to show up, so I switched off the computer. After I booted the PC back up, both drives showed up. However, the drives had switched device info with each other! I now have a 5TB Samsung (Seagate) drive that only shows 186GB, and a 200 GB (186GB) Seagate drive that shows 5TB capacity.
Yesterday I finally got around to attempting to fix them again. I have tried using Diskpart to clean, then re-initialize both disks. But even when the disks are not initialized, they each show the incorrect sizes. I was able to overwrite the disk ID of the smaller drive to it's original ID (I think), but the reported capacity remains the same as before (5TB).
I was on chat with a Seagate rep, but that went nowhere.
The computer they were attached to when this happened is running Windows Server 2012. They were both attached to a PCI USB 3.0 card at the time. When connected to my laptop running Windows 10 they still report incorrect capacities, so the problem follows the drives. So either something on each disc got overwritten, or something in the enclosures ?
I'm lost at this point.
