HDD GURU FORUMS

Hello everyone.

I am trying to recover this flash, but missing WP pin from the diagram. I don't have logic analyzer here to find it, maybe one of you has it?

Help much appreciated.

You usually don't need need the WP pin.

WP is not important.

I am aware of that. This chip has a lot of byte errors. I played with voltage levels without positive results. I was told by a colleague that actual read-retry routines in VNR won't be effective without WP signal. Is that correct?

IMHO no Try read this dump with slow mode or connect VCCq instead VCC.
