I have a special problem... my almost 2 years old unit (MZ-N505) is showing signs of aging (BLANK or NODISC 1/5, forward button acting as reverse SOMETIMES, among other things) but because it's intermittent problems, FutureShop won't take it back from me (they're like... it works fine!). My extended warranty wears off in a month of so... I don't want the unit to die on me a week after that. Any suggestions to 'make it die' faster, but in a way that's not detectable? Short-circuit, anything? I'm a biologist and don't know much in electronics... any help appreciated.
