Card #1 went into my camera, Card #2 I use for dsPIC file storage Card #2 I formatted in a card reader, its MBR ended up in sector 0. It works perfectly and I can read any file saved to it with a PC=20 Card #1 was formatted by the camera and its MBR is (apparently) at sector 0x2000 It really puzzles me. Frhed, if dd has made a good file, shows clearly that the MBR is at sector 0x2000 and yet that sector, as can be seen in the analyser trace, appears to be full of zeroes. The transition from high to low right under the first 0 of '0000 2000' is the 0xfe token, so there's no mistake that what follows is data, and that should be the 'ex.MSDOS5.0' etc string, not zeroes Either I'm doing something wrong or I don't know something One of those days Joe --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
