special device does not exist


Hello,
On my Debian's server (3.1) I connect an USB disc with 4 ext2 partitions.
when i mount the 4 3 partitions are OK but one (the biggest 600Go) won't to be mounted.I have the following message:

Code:
SCSI disk error : host 2 channel 0 id 0 lun0 return code = 8000002
Current sd08:31, sector 0
mount: special device LABEL=partition_name does not exist
.
after this message if i try to mount the partition it's OK all the partition are mounted.

Thanks to help for mounting all partition with the firs mount.

Fred

(sorry for my english but i'm french ... :-s )

You can only mount 3 primary partitions at the same time on a single disk. You need to create a primary and logical partitions if you wish to have more than 3 partitions on a disk.

I have formated my disc and remade 4 partition (sdd1 primary ;sdd5/6/7 logical)
Another little question => why it's sdd5 sdd6 sdd7? i have restart hotplug service and format again but there is always sdd5,6,7...)

So with only 1 primary partition (on the external device) why i can't correctly mount my disc (for informations that's always the same partition who wont to be mount and it's the primary.)

Thanks for your help

Edit: all the partition are "bootable"

What commands are you using to mount the partitions and what are the contents of your /etc/fstab file relating to /dev/sdd1 /dev/sdd5 /dev/sdd6 /dev/sdd7?

Hello,
to mount the partition i use this little script
Code:
#!/bin/bash

mount /mnt/USBdisk/alpha/
mount /mnt/USBdisk/BETA/
mount /mnt/USBdisk/gamma
mount /mnt/USBdisk/delta/
and the fstab is:
Code:
LABEL=alpha    /mnt/USBdisk/alpha      ext2    defaults,noauto 0       0
LABEL=BETA     /mnt/USBdisk/BETA       ext2    defaults,noauto 0       0
LABEL=gamma    /mnt/USBdisk/gamma      ext2    defaults,noauto 0       0
LABEL=delta    /mnt/USBdisk/delta      ext2    defaults,noauto 0       0
when i made a "cfdisk /dev/sdd" i see:
Code:
 
sdd1                    Boot                   Primary             Linux  ext2                      [delta]                     600001,28
sdd5                                           Logical             Linux ext2                      [gamma]                      50001,48
sdd6                                           Logical             Linux ext2                      [alpha]                     50001,48
sdd7                                           Logical             Linux ext2                      [BETA]                    300198,05
