What are the fixes to the “disk you inserted was not readable by this computer” error?
To access the files in devices like external hard drives, USB flash, etc., you should connect it to Mac. When you connect it to a PC or a Mac, you do it through the USB port. However, if there is something wrong with the system files or the disk, things can go wrong.
Corrupted system files or faulty USB drives can prevent you from accessing the data on devices. When t comes to an operating system like Mac OS X, you will see a unique error message. It will say “the disk you inserted was not readable by this computer” on the message box that appears.
We have a solid solution to address this issue to the delight of many readers. This method is tested to be perfectly working and convenient even for novice Mac users.
Well, let’s see how to deal with this issue. The process is mentioned in a step-by-step format so the users will be able to follow it easily.
1. Check your Mac
To perform this action, you should plug a different hard drive into the Mac (through USB). Then, observe if the system can find it. If the system can find it without any issue, the problem is associated with the previous USB drive. Your Mac is perfectly fine in this case.
2. Perform a check on the file format of the USB
The external hard drive or the USB you are trying to open has a specific file format. This respective file format is a key factor for the system to identify.
For instance, if the hard drive or the flash drive is formatted with NTFS, Mac will not identify it. To identify the hard drive or the USB, it must exist in FAT 32 file format.
However, to convert the disk into FAT 32, you will have to format it. The obvious outcome of formatting a disk is the loss of files. Therefore, we recommend backing up the data available on the disk before formatting it.
This is exactly when you will have to seek the assistance of a good backup utility tool.
