Try this: > > mount -t ext3 /dev/sda1 /mnt/sata150gb The mount command accepts the fs type before or after the paths, I tried both, also without fs indication. Fedora comp = server Windows comp = workstation In fact I did a 'mkfs -t ext3 /dev/sda1'. This ended in a total system crash. I tried twice, and also with Knoppix (Kernel 2.4 and 2.6), but no goal. So I formatted it the Windows computer with Arconis Partition Expert (yes it does ext3 as well). But it was still unmountable. Tomorrow I'll try it with Knoppix on the workstation, it has a Silicon Image SATA controller onboard (Abit NF7-S 2.0). So I'll see if the Promise controller is the troublemaker. Another strange thing is: "unknown mass storage controller: Promise Technology, Inc. PDC20375" - I thought the tx2 should be supported by the module sata_pomise (which is loaded). The drivers available at Promise's website is for Kernel 2.4 only. Should I update my atalib to the most recent version? Maybe there are som e options I have to change in my Kernel's config and recompile? Simon some german description of my server is on http://213.239.195.162/board/thread.php?threadid=20166
