Are you sure you're connecting terminal correctly?

I've never seen a Samsung drive producing blank terminal.

What are the voltages at the Tx/Rx terminal pins? Perhaps your client has damaged the UART port.

Are you checking the correct RX/TX pins ?
Did you try to gain TTL access with a known good drive ?
:D :D :D

:shock: :shock: :shock:

What tools are you using to gain SA/MC access ?

What do you mean by drive completly closed ?

If you have user area access most likely firmware is ok ....

I changed pc Now drive detected via sata to usb and I formatted C ( No important data) . Now it detected Bios( directly connected to pc)too. I have seen two partitions become Raw and one partition shows NTFS (D Drive)but if I open any folder access denied error. I f i checked Checkdisk it deleting entries in ( $130)
