Fix 1. Check USB Connection

Minor connection issues can also result in serious errors like clicking hard drive, disk structure corrupted and unreadable, and "Invalid media or track 0 bad - disk unusable." Thus, never mind checking the USB connection first. You can simply take the drive out and put it back in, or try a different USB port to resolve the issue.

Connect your external hard drive or other storage devices to another computer and check whether the problem remains, which can help determine if the issue is with the hard drive itself or with the original computer.
Connect your USB drives to the rear port, which offers a more stable power supply than the front ports.

Fix 2. Disable Write Protection

The read-Write protection on the hard drive can cause two errors in the Command Prompt: "Only one of the specified files was copied" and "Windows cannot run disk checking on this volume because it is write-protected."

To remove write protection:

Step 1. Run "Command Prompt" as an administrator.

Step 2. Enter diskpart and click "Yes" in the prompt asking for permission.

Step 3. Enter the following command in order:

list volume
select volume X (Replace "X" with the number of your write protected hard drive.)
attributes disk clear readonly

Step 3: Select the device that is write-protected and click Disable to remove the protection.

Fix 3. Format the Drive to Another File System

Formatting the drive to an improper file system may be the cause of the error "Invalid media or track 0 bad - disk unusable." Try formatting the drive to a different file system, such as FAT32, NTFS, or exFAT, instead of the one that's reporting the error.

Fix 4. Use Diskpart or Third-Party Software to Format the Drive

When you encounter an error while formatting a drive, try using the diskpart command or third-party software like Qiling Partition Master instead of the format command. This alternative approach can help resolve the issue.

To format your drive using diskpart:

Step 1. Run "Command Prompt" as an administrator.

Step 2. Enter diskpart and click "Yes" in the prompt asking for permission.

Step 3. Enter the following command in order:

list disk
select disk X
create partition primary
select partition 1
active
format fs=fat32 quick

Note: The command `fsutil` is used to assign a file system to a partition, and the `quick` option indicates that the format should be done quickly. For example, `fsutil` would be used with parameters like `fsutil fsformat` to format the file system, and `quick` would be added to the command to enable the quick format option. However, the correct command to format a drive is `fsutil fsformat` not `fsutil fs` followed by `quick`.

Using third-Party software makes formatting your drive a breeze, compared to using the more complex Diskpart. For those still unsure, an article on formatting a hard drive in Windows 10 provides a helpful guide.

In this case, rebuilding the MBR can be a viable solution to fix the error "Invalid media or track 0 bad - disk unusable."

If you're experiencing errors due to a Track 0 issue on an external hard drive, USB flash drive, or memory card, you can potentially resolve the problem by remarking Track 0. This process typically requires the assistance of a third-party tool, such as PC Tools 9.0.

Step 1. Boot your system into DOS environment from bootable CD/DVD disc and put another disc that has PC Tools 9.0 within.

Step 3. Navigate to "Select" > "Drive Type" > "Physical" > "Hard disk" and press "Enter".

Step 4. To proceed, locate the Partition Table, find the "Beginning Cylinder" where track 0 starts, place the mouse pointer there, and change the number '0' to '1', ensuring track 1 is not bad, then press "Enter".
