Too lazy to dig up the datasheets for those memories but I suspect they are rated at 10,000 or even 100,000 erase cycles. I feel it is unlikely wear should be an issue when used in this application. Since the erase operation is rather slow, sometimes you don't erase and overwrite when using this kind of device to store small data structures such as player settings, instead you invalidate one setting entry and then append a new. This way you normally don't waste an erase cycle each time you change a setting. Just speculating, have no idea if any of this is how it's done in the SB.
And for more speculation. Perhaps some power glitch could be derailing the state machines inside the Flash that perform the low level erase/write operations, leaving stuff half erased/written? Especially since the failures were triggered when playback was about to start. Now, given that this happened after you had replaced a bunch of capacitors that were past their prime the voltages should be cleaner than before, there's a lot to contradict this theory, but maybe it's still worth looking for ripple or spikes on the voltages. Anecdotally, I've seen some weird issues in some consumer electronics when I replaced electrolytic caps of questionable pedigree with the best stuff I could get my hands on, seems like the design was tuned for the low budget components. ------------------------------------------------------------------------ alfista's Profile: http://forums.slimdevices.com/member.php?userid=32396 View this thread: http://forums.slimdevices.com/showthread.php?t=117140 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
