first two methods on instruction kb831426 did not help.
remains installation of recovery console from win xp cd-rom and running chkdsk.
i have never installed recovery console. should i give it a try? do i have to fear anything. btw: its on winxp-sp3- sata-drive. do i have to install a driver too? thanks a lot.
