I have had problems recently after I formatted a USB flash drive on my Chromebook. When I plugged it in to my computer, it did not show a notification for the drive, or indicate that it recognized it in the "This PC (Computer)" menu.
To resolve this problem, I went to Computer Management > Disk Management > Right-clicked on the drive (it recognized it, but it just wasn't showing up) > New Simple Partition... > Followed the steps and formatted it to NTFS. I named it "Backups".
When I plugged it into my Chromebook, it recognized it, but it gave me a toast notification saying "Sorry, at least one partition on your device could not be mounted". When I opened it in the file manager, its name was "UNTITLED". When I put an empty folder on it, it did not show up in Windows.
I formatted the drive again in my Chromebook, and this time went to Windows and formatted it to a FAT32 filesystem, but I'm still having the same problems. The only help I found was here, where I was told to reformat the drive on my Chromebook.
This was working before I formatted it on my Chromebook, what has happened?
