Frequently Asked Questions
Do I need to eject before unplugging?
It’s safest, especially right after copying. Windows uses Quick removal by default, but ejecting makes sure writes have finished.
Can Windows 11 read a Mac-formatted drive?
Not natively if it’s APFS or HFS+. Use exFAT for drives shared between Mac and PC.
Why is the drive letter different each time?
Windows assigns the next free letter. You can set a fixed one in Disk Management.
