Hi, how are you? I have a MarkVision drive with a RM1135 controller and Hynx memory. The drive is read, I see its data, but only for 5/10 seconds, then it seems to disconnect. I disconnect, reconnect and the same thing happens. I need to recover data and this method is very cumbersome and annoying. I measured its power supplies and they are all active and pulsating (I measured with an oscilloscope). It seems as if it is protected by something. Can anyone help me? I can't find any datasheet for the controller or anything. Thank you very much!

Look at the voltage outputs of the controller. Another thing, sometimes the fault is the memory balls, greetings

It has a lot of pins, and I don't know what each one does.
