My girlfriend needed a flash drive to back up her Chromebook. I took an old 7g I had and formatted it to exfat (standard procedure here, nothing special). She plugged it in and had some issues with it, so I told her to see erase the drive from her Chromebook. Chromebook said it would delete all 4 terabytes (4tb) from the drive. Lol. Don't know how that happened, and was tempted to try it to see how it went, but did not want to mess up her laptop or wait days for a supposed 4 TB drive to format.

Tl;dr: girlfriends Chromebook thought a 7gb flash drive was 4tb
