ca'nt creat partition in iomega disk

I've a iomega external hard disk. from factory it comes with a NTFS partition and a small partition with something from iomega (which I don't want).

Since I only use the drive in linux, I opened the disk utility and formatted the entire disk, has a master boot record...
When I was trying to create a partition an error occurred:

 Error creating partition: helper exited with exit code 1: In part_add_partition: device_file=/dev/sdb, start=0, size=749422370816, type=0x83

got it
got disk
Error: Can't have a partition outside the disk!
ped_partition_new() failed

Since the iomega stuff wasn't deleted it is now giving me problems, because I can't create a partition.

Does anyone know how to workaround this?

the iomega stuff is has a virtual cd

Try using gparted on the live CD/USB.

Open up the iomega disk in gparted and go to Device ->Create partition table. That will warn you that everything on the disk will be lost, but as that doesn't matter to you, accept it and go ahead making an ms-dos partition table (the default for gparted).

You should now have an unallocated disk and can then make a new partition or partitions on it in whatever format type you want.

I recently bought 2 x Iomega eGo 1Tera for a customer who wanted it for simple backups rotations. I ran into several issues because of the encryption and the VirtualCD partition.

After calling Iomega support, they gave me some links to :

1. Remove the encryption from the USB 3.0 drive:
https://iomega-na-en.custhelp.com/ap.../kw/encryption

2. Remove the CD Partition on the drive:
https://iomega-na-en.custhelp.com/ap...tion/related/1

I was then able to do whatever I wanted with the drive.

Hope this helps

1 - ajgreeny it was a nice idea, I was able to format the drive and create a ext4 partition, but when I mount the drive in any computer I'm not able to write. --> read only file system

2 - a79 great advice, I had already stumble on that FAQ, and it solved one of my problems with the drive. --> There's no more iomeg virtual cd on it

Now, I got the drive clean, but I'm not being able to format the entire partition to ext4. With disk utility it keeps formating forever and it never ends, with gparted I get a read only filesystem...

[ajgreeny]

The permissions will all be wrong for the ext4 partition and for ease I suggest you both make and then label the ext4 partition using gparted. Call it iomega.

Now you need to change the ownership of the disk/partition to you so attach it so it mounts then use .

sudo chown -R username:username /media/iomega

And set read write and excecute permissions for anybody

sudo chmod -R 777 /media/iomega

This will allow full access to any directories and subdirectories on the disk for anyone and should work on any Linux machine.

Make sure you get the mountpoint right or you could cause big trouble, and sustitute your own username where I have used username.

What version of Ubuntu are you using? I recall a thread recently in which a person found that the support for disks with 4096-byte sectors was messed up in a slightly older version of Ubuntu (maybe 10.04, but I don't recall correctly). Upgrading to a more recent kernel, or maybe a whole Ubuntu upgrade, fixed the problem. You could test this out by using a "live CD" for a more recent version if you're running an older one.

That's a good suggestion ajgreeny gave you. I would add, have a look here:

Maybe manual formatting and mounting would help you....

Problem solved...

I was able to recover the HD with iomega software in widowz, next I got back to ubuntu and formated that partition using the disk utility...

Now I got the HD without the Iomeg virtual cd and ext4 formated

Thank you all
