What format does this drive show up on different system?
What mount command did you use?

Didn't use any mount command because can't see the hard drive on fdisk -l it should be shown as /dev/sdd1 or something like this.
I let my disk in the company connected to the server because i can access trough ssh or vnc, so can't see the format but I remember ntfs.

It shows in your mtab output below, commented out.

Are you using GPT? Does it show in gparted?

I comment out the /dev/sdd1, it was a test too, then execute mount -a but with no results.
Try with gparted too, the disk is not recognize.

It seems that the mtab table was only write when I reboot the system, Could be a configuration cause this?
Additionaly when the server was starting show a message "three virtual hard drive recognize by BIOS" or something like this I couldn't take a picture..

So is your problem solved? Your external hd is mounted on /media/EC48B69048B658D2

Yes, i could mount the external disk, but the problem is not solved, every time I plug a disk should reboot the system and the mtab is write, that's the problem.

Some info on mtab and fstab:
http://serverfault.com/questions/518...fstab-and-mtab
You removed the comment (#) from the beginning of that partition or it was done on reboot and now it is accessible. Your fdisk may not show the drive properly as stated in the output since it uses GPT, use GParted.

Sorry this line was manually added then commented by me, It was a test that I do too, then I delete this line too... When I reboot the computer this line was created as
/dev/sdd1 /media/EC48B69048B658D2 fuseblk rw,nosuid,nodev,allow_other,default_permissions,blksize=4096 0 0
automatically.

FYI mtab shows all currently mounted filesystems and their options. It is automatically updated by the operating system and should never be manually edited...
I'm not sure why Ubuntu is not automatically mounting the drive at the moment.
