@CaptRobovski said in Can I backup current emulator state - corrupted memory stick:

A quick question - should the filename under etc/udev/rules.d end in the suffix '.rules' ? I have other files in there, such as 99-input.rules, 99-bluetooth.rules.

No, the extension is not needed. Only the lexically order may be relevant of all rule files (cf. man udev -> RULES FILES).

The memory stick has left the factory mostly fine I would assume. It is the firmware that make things worse in use cases like this (as likely the USB spec has not been implemented by the letter by the vendor).

If you change make and model of the memory stick you may leave the power control rule enabled (adapt to the VID/PID). Does not have an impact unless you run on battery.

Or you can make a backup of you new memory stick and run it without the power control rule. If things repeat restore the memory stick and enable the rule.
However, if it repeats on a different make/model the issue could also be caused by the RaspBerry Pi Kernel USB implementation.
