You must “eject” a USB drive before you disconnect it from a computer. If you don’t, you risk corrupting data on the drive. This is because the operating system may be writing to the drive in the background, and if you remove the drive during a write, the data will be “incomplete” and thus corrupt.
How to eject a USB drive in Windows
- Start > My Computer
- Right-click on the drive and click “Eject”.
- A balloon-tip will appear at the bottom right of your screen saying it is safe to be ejected.
- If it doesn’t, you may have to close a program or window that is using the USB drive.
- Remove the USB drive.
