"Hey, I have a problem with my SanDisk flash drive. While trying to format the card, Windows prompted the first error message saying the formatting did not complete successfully. When I proceeded with the process, another error message popped up saying 'Invalid media or Track 0 bad - disk unusable.' What should I do?"
In fact, if you receive the “Invalid media or 0 track damaged – disk not usable” error after formatting SD card, USB drive, HDD, and so on, it indicates that the 0 track position is damaged. If there are bad sectors, you cannot open the SD card, USB drive, or other drives.
A track on a disk drive is a circular path on the surface of a disk used for recording and reading information. The 0 track is located at the very beginning of the disk and is used to save information about the disk's layout. Typically, the 0 track consists of the first 64 sectors of the disk (as you know, the first sector of the 0 track is the MBR – Master Boot Record). If the 0 track is damaged, you won't be able to access your USB drive or memory card normally. Luckily, receiving such an error doesn't necessarily mean that the 0 track is damaged; you might receive it due to other reasons.
This issue can be caused by a minor problem with the device or significant physical damage, including:
Before you attempt any repair, you might be concerned about the files on your hard drive. If you encounter a "bad track 0" error on your memory card, can you still recover data? If Windows can still recognize and detect the disk normally, you might have one last chance to retrieve files from the memory card or other device with the "Invalid media or bad track 0 - Disk not usable" error message. tools free data recovery software – Data Recovery Wizard will help you out to get data back from the problematic device.
Step 1: Select and scan the external hard drive
Step 2: Check the scan results

The "Invalid media or track 0 bad - disk unusable" error might be due to the drive being formatted with an incorrect file system. Generally, Windows supports three file systems: FAT32, NTFS, and exFAT. When you encounter this error message, you can try formatting the drive with one of the other file systems, excluding the one that reported the error.
When you get an error, you might be using a formatting command like “format e: /fs=ntfs.” If this doesn't work, you can try using the diskpart command or third-party software, such as the free partition manager – AOMEI Partition Assistant – to format your drive.
Format the disk using Diskpart:
Step 1: Run Command Prompt as an administrator.
Step 2: Type diskpart, and then click Yes when prompted for permission.
Step 3: Enter the commands in the following order:
Note that "fs" stands for the file system you want to format the partition with, which can be FAT32, NTFS, or exFAT. The "quick" means "quick format."
It's much easier to format a drive with third-party software than with Diskpart. Don't believe us? Read our article on how to format a hard drive in Windows 10.
As mentioned above, MBR is a part of sector 0 on the disk. If the MBR is lost or damaged on the disk, issues will occur for sure. Thus, it's worth trying to rebuild MBR to fix the "Invalid media or bad sector - Disk not usable" error.
If the error is due to a real Track 0 error on an external hard drive, USB flash drive, or memory card, you can work around the problem by commenting out Track 0. To do this, you'll need the assistance of a third-party utility called PC Tools 9.0.
Step 1: Boot from the startup floppy/CD/DVD to get into a DOS environment, and insert the CD that has PC Tools 9.0 on it.
Step 2: Use the DE.EXE command of the utility to repair the bad sectors. In order to edit Head 0, you must remove or disable the Read-Only mode in the "Configuration."
Step 3. Select 'Select' > 'Drive Type' > 'Physical' > 'Hard Disk', and press 'Enter'.
Step 4: The partition table will now appear. Find the “Starting Sector,” which is at the beginning of the first track (0). Position your mouse over it and change the '0' to a '1'. Make sure that the “Ending Sector” for the first track is correct, then hit “Enter.”
Step 5: Click “Save” to save your changes and exit.
Step 6: Restart the computer and format the hard drive with bad MBR.
Track 0 contains the first 64 sectors of the hard drive. If one of them is bad, you might receive an error message like "Invalid media or Track 0 bad - disk unusable" when trying to format the drive. Thus, try to fix bad sectors on the hard drive to get rid of the error.
If all else fails, your last resort is to send the external storage device in for repairs and seek professional help. For hardware problems like physical damage, none of the above will work, and it will likely need to be manually repaired.
"Invalid Media or Track 0 Bad - Disk Unusable" is a common error that plagues Windows users. There are eight possible solutions you can try to address this error when formatting a drive. Hopefully, one of them will perfectly resolve your issue. If your external hard drive, USB flash drive, or memory card is unrepairable and still under warranty, you can get it replaced, or simply get a new one.
