Somewhere I must have a 20GB IDE disk with my data from the 90's. The disk's circuit board burned out one day (damned PSU with bulged capacitors let the magic smoke out). I bought an identical disk on eBay and managed to transplant the good circuit board onto that disk, and had my data again. But then a college friend needed a disk so I took off the good circuit board, put it back onto the eBay disk and lent it to him, and of course he moved countries with just the promise to return it to me. Years later I managed to find another disk of the same model, but I can't find the board-less disk with the data... did I throw it away?
