USB stick corrupt
The supplied Prusa usb stick lasted me about 2 weeks before it broke. I had read about the poor quality of the stick so this was to be expected. The printer complained and my windows pc also could not read it. After formatting, I could save data to it but I did not bother to investigate further.
So I switched to a new sandisk drive. Now, again after about 2 weeks, my print pauses with a message that the file on the stick is corrupt. Resuming has worked, twice so far. Will see if the current 7h print will finish.
All my prints are sent via prusa connect, so the drive never leaves the printer. Have others experienced similar problems? What drives do you recommend?
RE: USB stick corrupt
I'm not a electronics guy so I can't even guess at what's going on but I've never found a correlation between USB "quality" (as gauged by price) and USB issues. I have one printer with an original Prusa USB drive that has never given me any problems, and I've bought four or five $30+ drives that failed within a couple of months. Like you, I never take the drives out. I now use the cheapest drives and just reformat them every now and then.

RE:
Same here.
Our CoreOne does not seem to like the USB anymore although it is not completely dead - yet. The one on our Mk4s does a little bit better but also seems vulnerable. We replace them with ordinary USB sticks from wherever we can get them. Indeed precious little correlation between cost and quality.
And - hard earned - advice from an ex- pro IT-er: never ever back-up on one single device.
RE:
I only had a drive get corrupted once, after I pressed the RESET button to get out of stuck filament condition. RESET really should NEVER be used, but some error conditions only allow Retry, which may or may not work.
