[QUOTE="Nerdyguy, post: 705579, member: 93333"] I lost all my data because apparently external ssd's are not hot swappable. Here is how it went: I installed Windows 10 on the SSD and moved all files from the HDD to the SSD while running the OS on the HDD. Then I put the SSD in the laptop hard drive space and booted up, but there were no files available. When I went back to the HDD and booted with that, I saw the files in the SSD again. I thought it might be a problem with permissions or Windows fast boot so I disabled it and unplugged the usb external hard drive converter that the SSD was in to make sure that shutting down wouldn't affect my ability to view the files. However, when I booted back up with the SSD, a bsod came up with a file system error, so the OS went through a startup repair process and restored some system files automatically. When I finally saw it boot up, expecting to be able to see the files, an error came up that said "We can't sign into your account". When I looked in "This PC", I saw that the SSD had very little data on it and all of the data I had loaded onto it previously was gone. It had essentially restored to the way it was right before I had started moving the files to it from the old drive, albeit the account error. It still has the error at the moment. What I want to know more than anything else is: why did the data get removed, and why does unplugging an external SSD corrupt its file system? Other than that, any advice on the account error would be appreciated. Thanks. [/QUOTE]
