hello Sir,
you are right, i was not being specific about my idea, sorrsy.
Im going to do a 2 weeks test run with an Arduino UNO. I am using a Data logger with SD slot.
My plan is to check the SD card for errors (my goal is to find bit flips). Thats why i was asking for a large .txt file (which can be filled with anything, just to have a setup to check for errors). In the 2 weeks i will check the.txt file repeatedly in 512-Byte blocks and use CRCs for every block. I will log few events (test correct, test corrupt...) to internal EEPROM.
So do you think renaming a film to .txt will do that?
Thanks a lot for your attention
