No it isn't in /fstab, i actually not mounted any partitions of that drive. The error appears (i tried under ALT Linux 2.2 and Slackware 9.0) during partition check after the hardware (disk devices) detected. I've created the FAT partition on wasted space (not even checked by ScanDisk) but it seems still not working
The hd drive is IC35L060 (IBM, 60Gb)!
