How to Fix SD Card Cannot Format/Unable to Write Error?

When your SanDisk SD card refuses to format, there are several tools and methods you can employ to fix the issue. Tools like disk utilities, SanDisk's own formatting tools, and data recovery software can often resolve the problem. If these solutions don't work, you may need to replace the SD card. Below are some tried-and-true methods to help you address the SanDisk SD card formatting issue effectively.

Solution 1: Inspect for Physical Issues with the SD Card

When you encounter the "Unable to Format SD Card" error, it's essential to first check for any physical problems with the SanDisk SD card. Begin by ensuring the card is correctly inserted into the device. Look for signs of looseness, dirt, or visible damage on the card itself. If there are any physical issues, contact customer service immediately to discuss repair or replacement options to prevent irreversible data loss.

Next, try inserting the SD card into another computer or Android device. If the card is recognized by these devices, you can attempt to repair it using software solutions. However, if the SD card remains unrecognized across multiple devices, it might be time to consider replacing it.

Solution 2: Remove SD Card Write Protection

Your SD card may be write-protected, which stops you from modifying or formatting its contents. This could be the reason why you're unable to format the card. To fix this, try removing the write protection with a simple method.

1. Press Windows+R, enter diskpart, and hit Enter.

2. In this diskpart window, input the following commands, and press Enter after every command:

● list disk

● select disk n (n is the number of the SandiskSD card)

● disk attributes clear readonly

● clean

● create partition primary

● format fs=ntfs quick

3. Once you see the message confirming that diskpart attributes have been cleared successfully, simply type exit to close the window. After that, formatting your SD card should be all right.

Solution 3: Format SanDisk SD Card using Disk Management

If your SanDisk SD card is missing a drive letter or appears as unallocated in File Explorer, it won't be visible for formatting. In this case, you can use Disk Management to either format the card or create a new partition. Follow these steps to format your SanDisk Micro SD card:

1. Press Windows+R, input diskmgmt.msc, and hit Enter.

2. Find your SD card, right-click on it, and select the Format.

3. Customize Format options like Volume label, File System, and Allocation unit size. Tap OK to start it.

Solution 4: Use Third-Party Software to Wipe SD Card Disk

While Windows tools usually work for formatting storage devices, they can sometimes run into errors, as discussed earlier. For a simpler and more reliable solution to completely wipe your disk, consider using AOMEI Backupper Professional. This software allows you to easily erase all data from any device without any hassle.

Before the wiping task:

If you still want your stored files in the SD card, you can make a file backup before wiping it out. And remember to connect this SD card to your computer properly. If your computer cannot read an SD card directly, use an SD card reader.

1: Download and install this tool, click Tools >> Disk Wipe.

2: Select the second option to wipe out all partitions, and click Next.

3: Choose the SD card you want to format and continue to tap Next.
