Unable to write to new Iomega external hard drive

Post by alfreddo » Tue Sep 28, 2010 7:12 am

I've just bought an Iomega external hard drive, 250 Gb capacity, and connected it via USB2 to my IBM ThinkPad T43 laptop running Linux Mint 9. I find I cannot write to it.

When I plug it in to the USB port, the Iomega HDD icon appears on the desktop. A right-click followed by 'Properties' displays the following:
Name: Iomega HDD
Type: folder (inode/directory)
Free space: unknown
Then a pie chart, with next to it:
107.7 Mb used
232.7 Gb free
Total capacity: 232.7 Gb

I typed out a test document in OpenOffice (test.doc) and tried to save it to the Iomega, but got this message:
'error saving document. /media/Iomega HDD/iomega test.doc does not exist.'

I then right-clicked on 'Properties' and got this:
Owner: 99 – user #99
Group: 99
The following boxes, 'create and delete files', and 'access files' were greyed out.
Finally this message: You are not the owner, so you cannot change these permissions.'

Moving from 'properties' to 'shares' seemed to offer a way round this, but when I ticked the boxes I got the message: 'You are not the owner, so you cannot change these permissions.'

So, is there any way I can change these permissions to make me the owner, or failing that, can I just reformat the drive so that it will work with Linux, and if so how do I go about it?

Typing lspci in the terminal gives this:

It's probably NTFS formattet.

Code: Select all

cat /etc/mstab
to be sure. NTFS is in general supported in Linux, but with some quirks. If you won't need to use the drive on any Windows machines, you should use another filesystem like ext3 or ext4. If you need Windows compatibility, but you don't have any files over 4 gb, FAT32 is the way to go. If you need Windows compatibility AND files over 4 gb, you need to put up with NTFS.

Presuming it's NTFS and the filesystem suffers from the common problem of having been removed from a running system without being cleanly unmounted, you have to do the following:

Code: Select all

cat /etc/mtab | grep Iomega
The first word, for example /dev/sdb1, is the devicename to use later.
Now:

Code: Select all

sudo umount /dev/devicename
sudo ntfsfix /dev/devicename
Fix any errors it asks you about. After it's done, re-attach the drive and check if you can write to it now.

Ask if you need any help formatting the drive or anything else.

A few months ago i bought one of those ( the 250GB Prestige) and had had a some issues with it:
-my propose was using it testing hdd for new distros, but even been empty i was unable to format it or install any OS on it.
-I got always the same error message as you "You are not the owner..."

The only way to solve this was with a GParted Live-cd, erase all partitions and redo from scratch.

I believe now that it's that "protection suite" thingy that is not not very linux-friend

Hi Fafler,
I've tried your suggestion with no result.

How do I format the drive with FAT32.

Thanks
