Started messing with my MiniDisc stuff again yesterday, mainly the Sony MZ-R900 and Sharp MD-MT831 units.

For the Sharp unit, I wanted to know how long the original Li-Ion battery lasted: it was about 9 hours! As for the Sony MZ-R900, it was a pretty short test run. Unit is fine.

Also redone a MiniDisc with more proper music files and created a new MiniDisc with the Sony MZ-DN430; it has been relegated to solely be a NetMD recorder now.

Also for today, it was to test the rest of the MD portable collection. So far:

Sony MZ-R37: fine. Previously, it was noisy, but it is quiet now. Odd.
Sony MZ-R500: repaired corner crack near the ENTER button.
Sony MZ-N510: fine.
Sony MZ-E33 (black): Severe skipping on all tracks on one MD. Cleaning the lens did not work, but simply greasing the track where the laser is located worked; no more skipping.
Sony MZ-E33 (white gold): I preemptively greased the laser track like the black version of the unit, and it is now fine.
