I have not yet found the date of manufacture but the drive was badly kept, he was in too humid, Indeed in dismantling the metalic cover the very end of the drive was slightly rusty and some screws, This had a big disadvantage: the disk sensor type between 1.44 and 720 mo ko, the sensor was well noted but the contacts going, result all my floppies fesait pass for 720 kb, so I dismounted and came to find the problem, and therefore first on the list of vériifcations these sensors, I have tested with an ohmmeter, nothing for 3, I found his weird, but I have on / off a good 50 groin times to stir the mechanics and be sure to have a good contact lorsqu'i and no ballast down when not, I plugged the sensor and magic merveillesement works well now, well it detects 720 and 1.44. Otherwise it works fine the head are very clean and works well as a standard player oussi in good condition, it has the advantage of being portable and consumes only in 250-260 mAh, it is also very quiet compared to inernes very bruillant the greater part of the time
