Can't Format an mSATA Drive, What Should I Do

I inserted a 125 GB Toshiba mSATA from my old laptop into the mini port on my old Dell Latitude e5540. I want to format it to use as a boot drive. Is there any way to do this?v

There are many reasons for not being able to format mSATA. Here are a few common reasons:

• Bad sectors exist on the mSATA drive.
• The mSATA SSD is write-protected.
• The mSATA file system is corrupted.
• The mSATA is infected with a virus.

If your mSATA drive is physically damaged, you need to replace it. If not, you can use a professional disk management tool to resolve the above issues and reformat it. 

I highly recommend EaseUS Partition Master Free, an all-in-one tool that can repair any failure of your drive. It offers an easy-to-use interface.

You can try the following solutions to reformat mSATA.

Method 1. Repair Corrupted mSATA

Step 1. Select the target disk, and choose "Advanced" > "Check File System."

Step 2. Select the "Try to fix errors if found" option.

Step 3. Click "Start" to check the disk error.

Method 2: Remove Write Protection from mSATA

Step 1. Open EaseUS Partition Master and go to the Toolkit section, and select "Write Protection."

Step 2. Select the write-protected disk and click "Disable."
