Many times Toshiba USB flash drives will show read-only errors on Mac. It happens due to several reasons, such as:
Mac allows users to modify the Sharing and Permissions to determine who can delete or edit data on the external hard disk. Thus, if you have set permission to read-only Toshiba, you can't write or modify it on Mac. To fix this, you need to change the permission settings on Mac to get read-write Toshiba USB access.
It is also a permission error. If you have intentionally or unintentionally locked a Toshiba USB drive, it won't open USB in write mode. To check whether Toshiba is locked or write-protected, right-click on the disk icon and select the Get Info to check the disk information. If it says ‘read this Toshiba hard drive’ even though it is formatted in the right file system, you can't write to the drive.
Sometimes formatting issues on external hard drives won't allow Mac to write or modify Toshiba USB. To fix the internal errors, use Disk Utility or, in the worst case, get a new Toshiba hard drive.
The NTFS file format is one of the common reasons behind Toshiba read-only errors on Mac. If the Toshiba drive is formatted in NTFS file format, it will only open in read-only mode on Mac. By default, Apple only reads NTFS formats as it is a Windows file system. Thus, convert NTFS files to Mac compatible format or use a third-party tool to mount NTFS drives.
It might seem like a daunting task to remove the Toshiba read-only error from Mac, but it is not. There are several systematic solutions available to fix read-only external drive issues on Mac, such as:
If changed permission setting is a problem for Toshiba read-only errors on a computer, simply change the disk permission settings from the Finder, as follows:

Step 2. Next, click on the arrow next to the Sharing & Permissions tab near the bottom of the window.
Step 3. Check the box that says Ignore ownership on this volume or toggle it off. It might ask to add the password of your Mac to enable the write mode.
If files on the Toshiba external drive show the read-only or locked message, this is also a permission error. It means that the Toshiba drive is password-protected or encrypted, and it needs to be decrypted for access. Here's how to unlock a drive on Mac:
Step 1. Connect the Toshiba volume to the Mac.
Step 2. Select the external drive from the Finder and right-click on the drive icon, select the 'Decrypt DriveName' from the list.
Step 3. Enter the password used to encrypt the drive.
Step 4. Decrypting the Toshiba drive will take some time, depending upon its size. However, once the process is done, you will be able to access the drive's content on Mac.
If the Toshiba hard drive is formatted to the NTFS file system, Mac will open it in the read-only mode by default as it is a Windows file format. The most compatible Mac file systems are FAT, exFAT, HFS+, and others. So, the only solution here is to format a Toshiba to the Mac compatible file format.
If your external hard drive doesn't contain any important files, go to Disk Utility and erase it. From there, one can select the several Mac suitable formats for Toshiba hard disk. The process works this way:
Step 1. Connect the drive to a Mac computer and go to Applications > Utilities > Disk Utility.
