Unconsistend behavior of micro SD card

[csierra67]

Hello,
I am using an Adafruit micro SD card reader connected by SPI to a Raspberry Pi PicoW to store values of a DHT22 probe.
I found an sdcard.py library that I installed on my board.
The sketch that is still under development works fine if I store only a few lines on the micro sd card. I removed the micro sd card from the reader, plug it in an SD card adaptator and plug it in PC.
However, if the file gets larger,e.g., 156 lines of text and 3kb, Windows does no longer detect it.
But I am able to retrieve it by a micro python sketch.
In another test, I did a write and test on the card by a demo sketch with only 20 lines. The demo worked but did not make the card detectable by Windows..
I would appreciafe any suggestion on this matter. Thanks a lot.

Further to my post, I rebooted my PC and my SD card was again detected. The issue may be more a Windows one than a Micropython code one..
