HOW - Splitting a 2 TB external drive?


I have bought an external USB drive (Seagate) for safe backup storage and now I need to divid it into two partitions, one half Linux and the other half NTFS. The program GParted (2012) doesn't read the drive and so I'm asking you guys how do I complete the task? Which program(s) can I use to create the partitions that I require.

Meaning ?. What error does gparted produce, and what messgaes do you get in dmesg when you plug the drive in ?.
I'd suspect a gpt drive - currrent libparted handles that ok, so gparted should. No need (yet) to go spending money, just get a gparted liveCD.

I've also recently bought a 2TB Seagate external USB/SATA drive.
The current gparted works just fine.
Note that if you are backing up NTFS data files with a Linux program, you can store it in a non-NTFS file system.

did one a month ago - gparted Debian stable has no problems, it also did a 2TB esata 4 years ago, so I doubt gparted is problem

possibilities:

1. drive is DOA; I was very careful to buy Toshiba so as NOT to get Seagate high density small form factor, significant difference in drive internals - more info needed re what does gparted show at launch
2. drive is automounted - needs to be umount-ed, 'sudo umount /dev/xxx' as shown by df or un-mount with gparted - it can't be changed while mounted
3. although it can be used as is (NTFS) if working, that doesn't always fit the needs
4. a complete reformat MIGHT solve it, but that could also void warranty or return
5. try it on a Win box if you have access to one, just to see if it is recognized and can be tested
6. also, I would suggest running steps to completion one at a time, not as a batch. 1st resize NTFS, then create new, then format new part, and be very patient!

best of luck

The Gparted live CD didn't recognize the drive ???
However, I solved the problem by using the Gparted that comes as part of the system in Linux Mint 16 Cinnamon ... that did recognize the drive and I was able to set up partitions.

Thanks for the reply
