If not solved :

“Ok, drive in question is 320GB WD Caviar SE IDE PATA 8MB cache. It is partitioned as EXTENDED with (1) logical NTFS and (1) logical FAT32 partition. FAT32 partition is 32GB and the rest is NTFS v3.1. Drive is running as Primary SLAVE w/ 80GB WD Caviar as Master. System is Win2K Pro/SP4. Went to upgrade video, wipe OS on 80GB primary master drive and start new installation. New installation does not see primary slave drive correctly. Lists in Disk MGR but doesn't show file system and also doesn't show the 2 partitions. Went to Chkdsk but received error: ‘The type of file system is RAW. CHKDSK is not available for RAW drives’.
