From linux fdisk -l will see them but you won't be able to mount them as they are of a non-mountable type (it is a few years now since I dealt with this problem and I can't remember the specifics now). dd wiped out the partition table and hence the three strange partitions. I think you will find that the windows software for the USB drive is possibly refusing to access the drive because the strange partitions have been removed. You may find that uninstalling the security software will allow you to partition and format the drive under windows again. > > I rebooted into the BIOS. USB 2.0 was enabled.

Possibly because the partition table got damaged by trying to re-write it without rebooting (see my comments above). If that is the case then dd if=/dev/zero of=/dev/sdb and repartitioning might work. I have also found that sometimes gparted seems to write the partition table in such a way that other partitioning software cannot access them, and can also lead to the partitions being damaged. I would recommend using cfdisk to create your partitions after running the dd command above, then use the installer to format them. I am not sure whether this problem is actually caused by gparted but I have experienced these problems many times and gparted seems to be a common denominator. > > After "Abort the installation" and turning of the power again, I > connected the cables to the hard disk drives. > > I booted 64 Studio 2.1 (amd64, Etch) from the SATA hard disk drive.

You could try using testdisk (http://www.cgsecurity.org/wiki/TestDisk) to recover the missing logical partitions. I have found it very useful for recovering from this sort of situation and I believe testdisk is available through the debian packaging system. Hope this helps, Ross. _______________________________________________ 64studio-users mailing list [email protected] http://lists.64studio.com/mailman/listinfo/64studio-users
