I've had the pmd661 since 2012, never had a problem before. But now it won't create a mplang1 folder when I reformat the sdhc card. It records but puts the sound files in the .fseventsd folder. I am on a Mac OS X Yosemite. I've tried to format and reformat several times, taken the card to a windows 7 machine. But nothing seems to be working. Any ideas?
