-bash-3.2# diskutil list

/dev/disk0
  #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:      GUID_partition_scheme                        *1.0 TB     disk0
  1:                        EFI EFI                     209.7 MB   disk0s1
  2:                  Apple_HFS Macintosh HD            999.3 GB   disk0s2
  3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

/dev/disk1
  #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:     Apple_partition_scheme                        *1.3 GB     disk1
  1:        Apple_partition_map                         30.7 KB    disk1s1
  2:                  Apple_HFS OS X Base System        1.3 GB     disk1s2

The first two of these are normal. The rest are odd. I'd detach all external devices with the exception of the mouse and keyboard. It could be some external device is reporting badly. Partitions are reported below the device. Your seem to be having a problem with too many devices reported. Don't know why.

Each of these entries is reporting a storage device.

/dev/disk#

You know the drill. Add back on device at a time & see what is up.

What does this say?

mac $ ls -l /Volumes/
total 16
drwxr-xr-x  109 mac   staff   3.7K Apr 15 14:17 Backup/
drwxrwxrwx@   1 mac   staff   4.0K Apr 15 14:17 COPYIT/
lrwxr-xr-x    1 root  admin     1B Apr 15 00:23 Macintosh HD@ -> /
drwxr-x---   11 mac   staff   442B Apr 15 14:17 mac copyit/
mac $
