Could someone direct me to a subreddit for SD card formatting/partitioning issues? (alien.top)
 

I was getting good answers here but the Mods whacked the post and responses. Geesh

As far as I can tell this request does not violate /r/hardware rules. Even rule #5. I wasn't looking for tech "support" but rather just asking for this communities guidance/experience on SD cards partition table and formatting.

SD Card without MBR or GPT: I need a "RAW" SD card in c/[email protected]
[–] [email protected] 1 points 10 months ago

To clarify: I have written my own "disk operating system" for an MCU. I simply reads and writes for the first 2Gb of an SD card. I need to write my target image to be loaded on to the MCU at 0x000 and I find that the MBR resides there. I have to load the image from a desk-top PC and the MDB and GPT put me way further into memory (0x01FF).

SD Card without MBR or GPT: I need a "RAW" SD card (alien.top)
 

Is it possible to buy RAW SD cards? I mean without a master boot record or partition table. I have been using WinHex to write zeros to all the memory addresses thereby wiping out the partition tables, but this is time consuming. Can I just buy them "blank"? Does anyone have a source?
