What happens if you force eject a hard drive on a Mac?
When you force eject an external hard drive by directly unplugging it from your Mac, you may face drive corruption, data corruption or loss, and hard drive recognition issues in the future.
A force disk ejection will interrupt the ongoing interaction between the external drive and the operating system. The file system structure of the drive will be corrupted if the operating system doesn't properly finalize file read or write operations on it in time.
If data hasn't been completely written to the drive before disconnecting it, unsaved information may be lost and data in transferring may be corrupted.
Repeated force ejections can lead to problems with the drive mounting or recognition later. It may also cause physical damage (bad sectors) to the hard drive, especially with spinning drives (HDDs).

External drive not recognized, showing up, or mounted after force eject on Mac, how to fix
A force ejection may corrupt the drive or not. The external hard drive that is not showing up on your Mac after a force ejection may also have a faulty connection or be damaged.
Therefore, you are suggested to troubleshoot with the following ways to fix the external hard drive that's not recognized after force eject on your Mac.
Tips: If you are afraid of permanent loss of valuable data on the external drive, you can download iBoysoft Data Recovery for Mac and see if it can detect the drive. If it can, use the tool to recover files from the external drive as early as possible. Then you can feel relaxed to fix the hard drive in the following ways.
Way 1: Restart your Mac and reconnect the drive
The previous improper ejection broke off the data transfer between your Mac and the external hard drive. This time when you connect the drive, your Mac can't continue the previous uncompleted progress.
Thus, you can power off and then restart your Mac to eliminate the system caches and refresh the operating system. Then, reconnect the external drive to your Mac completely, slightly, and properly to let your Mac recognize it.
Way 2: Check the USB port and cable
Perhaps, your external hard drive is not detected by your Mac due to the faulty connection rather than the previous force ejection. So, we suggest you check the connections.
- Try another USB port if your Mac device has more than one. If you use a USB hub, plug the drive into another USB port.
- Change a USB cable.
If the external drive is still not showing up on the desktop or Finder of your Mac, try the next way.
Way 3: Check if the external drive shows up in the Disk Utility
Disk Utility shows all the detected hard drives connected to the Mac. Therefore, when you can't find the external hard drive in the Finder sidebar or on the desktop, go to Disk Utility.
If the external hard drive is not showing up in Mac Disk Utility, it indicates that the drive has hardware issues. You can send it to a local repair center.
If the external drive appears in Disk Utility but is in an unmounted state, follow the solutions below.
Way 4: Manually mount the external drive
Sometimes, your external drive's driver gets corrupted through an "improper ejection" of the drive, making your Mac won't mount the drive again afterward. Thus, the drive is in an unmounted mode in Disk Utility.
In this case, you can click the Mount button on the toolbar to try to manually mount the external drive.
- Go to Disk Utility.
- Select the external drive and click Mount.
Way 5: Run Disk Utility First Aid to check the external drive
If the external drive cannot be mounted on your Mac even with the Disk Utility's Mount button, it shows that the drive has file system corruption. You can try to run First Aid to check and repair the external hard drive that won't mount after improper ejection from the Mac.
- Go to Disk Utility.
- Select the external drive on the sidebar and click the First Aid button on the toolbar.
- Click Run on the pop-up to start checking the drive.
After doing some disk repairs, check if the external drive is recognized by your Mac device.
Way 6: Recover data and reformat the external drive
When you get to this point, it means that the external hard drive is seriously corrupted. Reformatting it is the only way to fix the external hard drive that's not recognized after force ejecting from your Mac.
However, reformatting the drive will erase all its contents. Since the drive is unmountable, using a data recovery app is the only chance to recover the files.
