. There are two identical 300-gig hard disks on my computer; but only one is accessible. When I do 'df' I see only this: Filesystem Size Used Avail Use% Mounted on /dev/sdb5 7.7G 3.5G 3.9G 48% / /dev/sdb7 138G 9.5G 129G 7% /home Hardware detection shows two hard disks: sda and sdb: #1 ‎ATA MAXTOR STM332062 Old device file: ‎/dev/sda Partitions Primary partitions: ‎1 (sda1) Misc Geometry: ‎38913/255/63 (CHS) Disk controller: ‎0 -- Module: ‎sata_nv #2 ‎ATA MAXTOR STM332062 Old device file: ‎/dev/sdb Partitions Primary partitions: ‎1 (sdb1) Extended partitions: ‎3 (sdb5, sdb6, sdb7) Misc Geometry: ‎38913/255/63 (CHS) Disk controller: ‎1 -- Module: ‎sata_nv When I tried to use 'gparted', I see this error: error: libhal_acquire_global_interface_lock: org.freedesktop.Hal.Device.InterfaceAlreadyLocked: The interface org.freedesktop.Hal.Device.Storage is already exclusively locked either by someone else or by yourself So, I booted "Part Magic" Linux live CD and screen captured the contents of the two hard disks as shown at these links: http://upquick.com/temp/gparted1.png http://upquick.com/temp/sda.sdb.png I want to use the second hard disk to backup all my files on the first hard disk. What do I need to do to get the second hard disk unlocked and mounted so I can copy all my files onto it? --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
