I bought exactly the same model of card you have, and I reproduced and corrected / worked around the problem. Please let me know if you get the chance to test the release above. Your card should work now. I also uploaded STL files for 3D-printing an enclosure which has a slot and other minor modifi...

Here is another debug build which will wait 4 times longer. Could you tell me if it makes any difference? Sorry, here it is: https://www.raphnet.net/electronique/sdcartJR/sdpart_debug2.zip That worked! Kinda. Once. sdpart.com worked once when I used it right after booting up. But if I try it a seco...

I took raphnet's 3d print cartridge case from here https://www.raphnet.net/electronique/pcjr_cartridge/index_en.php Had a friend print it off for me and then made some modifications with an xacto knife. Turned out pretty good! https://youtu.be/oIkADjsC828 Wish I had stl modifying skills so I could m...

Sorry for the delay! Unfortunately I do not see anything wrong in the above, or anything that would explain why reading the MBR fails... Could you try this build of sdpart.com? I've enabled error tracing, knowing exactly where it fails should help. https://www.raphnet.net/electronique/sdcartJR/sdpa...

Let me know if there is anything else you'd like me to try with these Transcend cards. I'd even be willing to send you one. Otherwise I'm sticking them in a drawer and forgetting about them for now as I got plenty of other cards that work. Been playing games off of it. It pairs really nicely with th...

I only did the software update and that got it working.

FYI with the new version I was able to use my larger sd cards! Yay!! 8GB SanDisk MiscroSD HC 256GB SanDisk Ultra MicroSD XC Had to stick smaller FAT partitions on them of course. Nice thing was I could put a small partition on and then fill the rest with a large partition and the small partition sti...

So sadly I can't get to the 'p' command. This is from a freshly opened one without me having messed around with it. Please try the new release (v03). I modified sdpart.com to display card information before attempting to read the MBR. Maybe it will show something that will help me understand how I ...

This SD Card not so much. https://www.amazon.com/gp/product/B00FYX1ABQ I get a "No suitable partition found.Init failed" error. I tried reformatting the SD card, tried wiping the partition and recreating it and it didn't work. Could you try running sdpart.com to see what kind of card it i...

P.S. Just for funzies I did try some SD Cards that are too big. They had a "Divide overflow" error.

Interestingly after trying those swapping to the working one didn't work anymore. It started having a "File allocation table bad, drive D". Had to reboot to get it working again.
