Recording file(s) not created on particular SD-Card

[nitin710]

Describe the bug

• A record begin does not create a file on the SD-Card. EmotiBit FW or SW do not throw any error.

Expected behavior

• When a recording session is started, a csv and info.json file is created on the SD-Card.

Additional details

• EmotiBit software version: v1.11.1
• EmotiBit firmware version: v1.11.1
• EmotiBit hardware version: MD-V5
• OS version: Windows 10

To Reproduce
Steps to reproduce the behavior:

1. Use the specific SD card that shows this problem.
2. Start EmotiBit
3. Connect to Oscillosocpe
4. start a record session
5. end a record session
6. inspect SD-Card contents.
7. Verify no new files were created on the last recording session

Notes

• This SD-Card was previously working (as indicated by earlier recordings on the card)
• It is weird that the info.json is also not created since that is a static file that should "just write" in a big dump to the card
• It is weird that no errors/warning are thrown by the firmware relating to file creation. We clearly have a check in place
