well, i just did an experiments on my old pentum III computer. one of the slave hardisk listed as /dev/sdb1 (EXT2) and /dev/sdb2(SWAP) i run the command /dev/null > /dev/sdb1 and suddently, i cannot cannot read or mount my /dev/sdb1 anymore even after i restart my computer few times. i have message saying media failure or disk I/O error.
now i am wondering. whether it is because the command i just executed or my hard disk is really dying?
