Why can't clear the flag read-only state on the drive?

Brought a flash drive with write protection, using Diskpart removed the read-only, but read-only state remains true. In the registry StorageDevicePolicies created the file WriteProtect and change its value – all in vain. How to remove the read-only state from the stick?

As a variant, the controller could put the drive in mode "read-Only" due to wear of the NAND flash-memory chips.
Such behavior is especially fond of the device from Transcend.

To do additional diagnostics, you can use R. tester-but this should give at least a better idea of what happened.

And test read-CERT Tool, for example, Read Logical, mode=SEQUENTIAL, step=0 passes normally, with a steady schedule? - Devin75 commented on June 3rd 19 at 19:32

In General it looks good.

Next, it's necessary to dig with your hands, you can start with the determination of iron, and then find a utility from the manufacturer (if available).

Thing to remember is that the software manufacturer takes down information from the flash drive permanently. - Devin75 commented on June 3rd 19 at 19:38
