I am trying to format a new external HDD of ASUS (model AN300). Ubuntu recognizes only a "CD ROM" when I plug it to the computer, names ASUS Webstorage. I tried to follow instructions, on this link.

But when I type fdisk -l on my laptop I don't get any line, so I don't know if and where the hdd is mounted.

I also tried this . But nothing work for my hdd, how can we beat the system?

if you install/run GParted this is an excellent tool for organising partitions and formatting drives. Downloadable from the Software Centre – SimplySimon Jun 4 '13 at 10:08
Hi Simon, I've tried to open the device with GParted, but it doesn't even see the hard drive that I plug. When I press devices on GParted is shows only the internal hard drive at /dev/sda – Ohm Jun 5 '13 at 10:08
I'll leave you with @Mitch and his knowledge, as I'm still new here :) – SimplySimon Jun 5 '13 at 10:32
@Mitch This link seems to suggest there is noway to use this HDD in Linux. – user68186 Jun 5 '13 at 16:15

Hi, I tried to open the hard drive through the disk utility but it doesn't show the hard drive, it just shows a Virtual CDrom in which there is a program of ASUS for Webstorage. – Ohm Jun 5 '13 at 10:11
When you highlight that, what size does it show? – Mitch Jun 5 '13 at 10:14
Hi, I try to put an image here but it says I don't have enough reputations to do that...In any case, it shows MODEL : ASMT Virtual CDROM, and for Device : /dev/sr0 – Ohm Jun 5 '13 at 10:15
Upload the image to the web, give me the link, and I'll add it. – Mitch Jun 5 '13 at 10:20
If you boot from LiveCD, do you see the drive? Is the drive plugged in to a USB2.0 or USB3.0 port? – Mitch Jun 5 '13 at 11:00
