Solving Mac USB Flash Drive Detection Issues: A Step-by-Step Timestamped
It is important to troubleshoot and try different methods to fix a USB flash drive that is not showing up on a Mac, including checking for detection, trying different USB ports, adjusting preferences, using Disk Utility, running the First Aid tool, and ultimately considering replacing the drive if all else fails.
1. 🔍 Make sure your Mac detects the USB flash drive by checking the system information in the utilities.
2. 💡 If your USB flash drive is not showing up on your Mac, try unplugging it and plugging it into a different USB port.
3. 💡 Try accessing the USB flash drive again and if it doesn't show up, use the easy approaches to troubleshoot.
4. 💡 Make sure to check the "external disks" option in the Finder preferences for both desktop and sidebar to troubleshoot USB flash drive issues on a Mac computer.
5. 💡 If the USB drive doesn't show up, try using Disk Utility in the Applications folder.
6. 💡 Click on the drive, run First Aid to repair any errors, unmount the disk, wait 10-15 seconds, then plug it back in to access it again.
If your USB drive is still unmounted in Disk Utility and can't be fixed by the utilities, you can try to reformat it to make it mountable and show up on your Mac again. The sad thing is that reformatting the USB will erase all contents on it.
If you don't want to permanently lose your irreplaceable files on the unmounted USB drive, you can use iBoysoft Data Recovery for Mac to quickly rescue files from it.
- Download, install, and open iBoysoft Data Recovery for Mac on your Mac device.
- Choose your unmountable USB drive on the main interface of the tool, then click Search for Lost Data.
- Wait for the scanning process to end and browse the results.
- Preview and select your desired files, then click Recover to save them to another drive or on your Mac.
7. 💡 If your USB flash drive is not detected on your Mac, try it on another system and if it still fails, consider replacing it.
