He's right you know ! I've just checked the box of random adapters I never use and sure enough there as USB one in there. Thanks pepe.

Hello,
My two cent : my "noname" removed NAND connected to GPIO of STM32 have the same behavior on B/R pin when there is no or too low pull up resistor. It take about 800ms to 1200ms to get reset busy flag....

The Busy/Ready pin is open drain. A pullup resistor is mandatory. In any case I believe the OP's BSY problem is due to error recovery issues.

Yes, that why I understand and read after notice this behavior.
A capacitive effect make the edge very very slow to rise above the Th-H (0.72xVDD). with proper pull up, the edge is "straight".
But I just begin to wonder I BSY refer to busy pin (R/B)... I'm off topic ?

When the OP is talking about "busy", it means that the entire USB device is being seen as busy by the USB host, in this case the data recovery tool.

It would still be nice to know how HDDSuperClone handles that.
