These days /dev/sd* names are used for PATA, SCSI, SATA, and USB drives. In the case of the bootup post-installation onto the USB drive on Jack's box, the boot never got to the kernel. > This caused problems in that the "?" letter of the drives were not always > the same.

In the Ubuntu install, Jack also tried disconnecting the USB drive prior to the install, and in that case the /second/ internal hard disk showed up, but not the first!. ;-) -- Chris -- Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) Vassar College Dec 5 - SysAdmin Panel Jan 9 - High Performance Computing Feb 6 - February Meeting
