Maybe it's related to recent updates, or my computer is starting to die: Anyway: Today I had plugged in my USB stick and attached it successfully to "vault". I had opened a file from it. The suddenly within one second, I saw the stick being disconnected and reconnected, and the "vault" failed to write the file.
1) Is that disconnect expected?
2) Is it expected the a disconnect/reconnect uses a different disk (xvdj vs. xvdi)?
3) Is it expected that the partitions appear twice in the file manager (see attachment)?
