those li-ion batteries wont even fit in the battery compartment of the hi-md units. those batteries are replacements for old discontinued sharp models.

i bought a rh10 about 2 months ago, and i noticed that it had scratches straight out the box. i had to return it because the lid kept popping open, and when i got my replacement (brand new in box), the new unit had even more scratches, not to mention something that looks like an oil spot on the oled.

serials numbers of problem Himds: 4AAA1915E 4AAA1705E

i get the same problem, but i always lay my minidisc recorder (mznh900) flat on my desk. i bought about 25 hi mds, and opened 6. two of these six give me errors similar to the one you are experiencing. when recording, everything will go smooth, but when i play the recorded material, the track plays, but no sound comes out. playing it thru my pc, i get an error. i can reformat the whole disc, then record over, and about 50-60% of the time the same thing will happened, at around the same area of the minidisc (near the end, at last 150 megabytes or so, depending upon which of the two problem hi-md discs i use). the other 4 himd mindiscs, i can reformat and fill it up over and over again with no problems. maybe some hi-md discs are defective?
