Windows 10: how to fix bad sectors and write protected in the same USB

I have a 256GB USB, free space 117GB, it is SanDisk USB. I cannot copy or format it because of write protected. I have used all methods: using Regedit.exe, EaseUS Tools M, Diskpart Command, then I used AOMEI Partition Assistant to format it, but only 48% it stopped because of bad sectors.

I had the same problem with Kingston USB before, but it is only 57GB, with this one I cannot just throw it away.
Please help me fix it. Thank you. I am using Windows 10 version 1909

HDD Bad Sector

Hi Nataniel!

I am not sure what your question is exactly, but one thing I'd recommend for sure will be to look for a replacement drive since there is already a bad sector on your current one.

Basically there are two kinds of bad sectors - hardware and software:

• Hardware ones are caused by physical damage or becoming magnetically fixed, and they are unrepairable. In short, once they appear it's only a matter of time (no way to say how long) until the HDD fails.
• Software bad sectors on the other hand occur when something called an Error Correction Code (ECC) doesn't match the contents of the hard drive. These can be repaired by overwriting the data on the drive with zeroes (a.k.a. low level formatting) and sometimes
  by running a **chkdsk [write the letter of the drive:] /r** in the CMD.

As for getting the information from the drive if one of the partitions fail, most likely you won't be able to, which is why I'd suggest to make a regular backup of your most important data.

Hope this helps and feel free to ask any questions you may have.

Hi Darren, I am Rob, an independent and a 10 time and dual award MVP specializing in Windows troubleshooting and Bluescreen analysis. Please remember as independents we are not responsible for the development of Windows or the computer hardware and drivers.

I use a lot of cards so just fought this battle on two more of mine yesterday. Sometimes they can be revived and sometimes not.

Make sure the card does not have a switch on it that makes it read only. If it does work it back and forth a few times.

Try the card on another computer. If same issue then it is going or has gone bad.
