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

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
