Thanks for the report! What is the date code/model number on the back of the calculator? Also what were the formatting settings you used (cluster size, etc)

[KnightsWhoSayNi0]

Woops forgot about that!

Formatting Settings

Capacity: 14.4 GB
File System: FAT32
Allocation Unit Size: 16 kilobytes

More calc things because im dumb

Code: L-0318L

[mateoconlechuga]

As a pro-tip, you should set the allocation unit size to 64KiB for best performance. Anyway I'll get those materials and see if I can reproduce it.

It was the drive.
Tried it with a different drive and it works perfectly.

[mateoconlechuga]

Well probably not "perfectly" as there might be intermittent issues. I'm going to keep this topic open because I was able to reproduce this issue on another drive I have, so until I fix that I'll be working on making this more stable.

[KnightsWhoSayNi0]

I personally think the issue is just the cheap usb drive, but there definitely are some problems so this should be kept open.

USB support is being rewritten with many improvements, check back when a new version is released, I guess.

Ok
