Hi,
I installed fedora core 6 new today but it doesnt find my eternal hard disk (200gb seagate). another computer with fedora core 5 finds my hard disk. So the problem doesnt come from my hard disk. But fedora core 6 finds the kingston data traveler(1gb). I cant figure out this problem can someone help me. Thank you.

Is it formated NTFS? Maybe you need ntfsmount or ntfs-3g: http://www.linux-ntfs.org/ http://www.ntfs-3g.org/

ı dont know but if it was ntfs is it possible for fedora core 5 to read it. I installed ntfs but it says ı should mount the device but ı cant see the device so ı cant mount it. Thanks

it is not it is fat32. i typed dmesg and this is the result

should be able to mount it manually.

Something like:
mkdir /mnt/sda1; mount /dev/sda1 /mnt/sda1 -t vfat

Or insert into /etc/fstab and it will be mounted on reboot.
/dev/sda1 /mnt/sda1 vfat defaults 0 0

No clue why it isn't auto-mounted on-demand. The old fstab-sync mechanism has not been used since Fedora 4 but it still works...

If you want to mess around with mounting things the new way, try man automount; man auto.master and see where that leads...

The first thing you said worked ı moundet it under sda1. Thank you.
