But, there are times when sellers sell duplicate or SD cards that get corrupted after a use or two or such memory devices whose actual size is less but the mentioned size is higher and fixing these kinds of memory devices is not possible.
Fix SD Card Showing Wrong Size
You must make sure the memory device you are purchasing is of good quality, and most importantly it has to be a genuine product. So, I have 6 ways to fix SD Card Showing Wrong Size which are given below.
1. Scan SD Card Or Pendrive with Antivirus
There are times when you download stuff or transfer files from other systems to your memory cards or pen-drive then the virus comes to the memory card. There is a possibility that the viruses could be consuming the space or eventually might corrupt the memory device on a temporary basis.

All you have to do is scan the external memory device either from the Windows Defender or any anti-virus software you have in your system. I would recommend Bitdefender to scan the device because it is free of cost and the free version of this software does the job pretty decently.
2. Clean Pendrive using CMD to Fix Sd Card Showing Less Size
To clean the respective memory card or pen-drive from the system CMD, go through the steps mentioned below.

Steps:
- Click on windows search bar
- Search for “Command Prompt or CMD”
- Right click on it and Run it as administrator
- Type “diskpart” and enter
- After entering DISKPART type “list disk” and enter
- Then type “select disk (disk number) ” and enter
- Now type “clean” and enter
- Now type “create partition primary” and enter
- To format type “format fs=ntfs” and enter
- And you are done
Head on to the next method if this one doesn’t work for you.
3. Delete SD Card Partition to Fix Sd Card Showing Incorrect Size
For deleting the SD card partition from the system and creating a new one again in the system, go through the steps mentioned below thoroughly.

Steps:
- Click on windows search bar
- Search for “Command Prompt or CMD”
- Right click on it and Run it as administrator
- Type “diskpart” and enter

After you are done with the CMD commands head on to the disk management part to allocate the external memory device:
- Click on the windows search bar
- Search & Open for “disk management”
- Right-click on the particular disk i.e. the damaged one
- Select “New Simple Volume”
- Click on “Next” until you see the drive letter selection window
