Samsung 32GB microsdhc 10 class MB-MSBGA/KR 8806071556239
Bought two of them recently from an eBay vendor. They will format and are recognized by the M10.
Unfortunately, during continuous recording, only the first file is written cleanly. All subsequent files written are corrupted during continuous recording. Ran them yesterday afternoon, and again in the overnight, with both my recorders rolling. Today, I put in my trusty Transcend 16gb Class 6 cards, and they recorded and wrote continuous without any file problems.
NOTE: I did put one in my Samsung Galaxy S2 phone. Formatted with Jelly Bean with no issues, except only 30.2 storage space. Copied an entire show I recorded, 16 bit flac. Played it with Winamp Android app with no issues.
