Why can't I remove the read-only state flag on the flash drive?

Question

USB flash drives

They brought a flash drive with write protection, removed the read-only value via Diskpart, but the read-only state remained true. In the registry in the StorageDevicePolicies, I created the WriteProtect file and changed its values ​​\u200b\u200b- all in vain. How to remove read-only state from flash drive?

Answer 1

Alternatively, the controller could put the flash drive into "Read-Only" mode due to the wear of the NAND memory chips.
Devices from Transcend are especially fond of this behavior.
You can do additional diagnostics with R.tester , this should give at least a better idea of ​​what happened.
