View Full Version : Seagate 1TB external HDD-can't partition

28-09-2009, 10:00 PM
hi.. can't get the Seagate External HDD to partition into , say 3x300 logical drives.
In the past I have used Norton Partition Magic 8 to do the partitioning of the 80GB & 30 GB HDD's installed in my computer. I am not familiar with the Disk Management of Windows XP Pro... have never used it.

Problem is: Norton Partition Magic 8 shows the 1TB Seagate, (953,867MB) but lists it as follows:-
Partition: (*)
Type: Unallocated
Size MB: 0.0
Used MB: 0.0
Unused MB: 0.0
Status: None
Pri/Log: Primary

The other two drives are C with D as a 40GB partition of the 80GB Master HDD, and drive E is the 30GB slave. All internal IDE drives...there is a colour border around each drive that didplays the drives Type/Status..ie Purple = NTFS, Blue = Extended
The colour border of the 1TB HDD is Yellow; which is keyed as meaning " Other"
In the rectangle that shows the drive are the size and type; namely
953867MB BAD
The drive has 350GB of data on it and it is all accessible

I cannot use Nortin PMagic to partition the drive.
Attempting to use the Disk Management in Windows XP Pro SP3 to create partitions is a no-go either..remember I've never used it before but attempting to create a partition on the 1TB drive , working from the 'How to's' in Help and Support, Using the Windows Interface and trying to Right click a free space on the drive gets me no other options thjan these listed here;
Change Drive Letters and Paths
Delete Partition
When I try to use the Command line, after entering the necessary diskpart>list disk etc , and try to create any form of partion (extended/logical/whatever) and having antered in a size 'n' as 300GB, I am getting the return in the Command Prompt window as being " The arguments specified for this command are not valid'.
All Drives show in Computer Management as being 'Basic' Type, with C drive shown as System aand The Seagate 1TB as 'Y' Expansion drive..."Active".... 931GB NTFS.

Long and short is : can these external HDD's be Partitioned?
On saturday I went to DSE where I puchased the drive tuesday week back to enquire about the "BAD" showing in NortonPMagic. After saleman/tec plugged the drive into a Dualcore Laptop running Vista, all showed as ok in com management. as it does on my computer. however the ssisstant went online to checkout Nortons capabilities...he suggested that Pmagic 8 cannot find a drive over 750GB....bummer...
He also said that thes drives cannot be partitioned.....
Is this true or/and do I have a prob with Computer Management an that ,a/ I dunno how to use it..b/ something's amiss with my com because of the options that are available to me in Windows Interface do not include "Partitioning"
?????????????????????????????????????????????????? ?

Compaq Presario S3010AN desktop
AMD Athlon XP 2000+ ..1.67GHz
1.5GB PC2700 RAM
Win XP Pro + SP3
WD 80GB Master HDD + 30GB Bigfoot Slave HDD
And this Seagate 1TB External HDD ( ST310005EXM101-RK)

Help and advice well needed, thanks.
I cannot get back to view any replies to my thread until tomorrow early evening.

Use G-Parted available on most Bootable Linux CD's. I use Puppy. It is fast and very reliable. It will handle situations which are beyond Partition Magic.

The Windows Disc Manager is a waste of space for anything other than changing drive letters, and is very slow.

For an external drive, make sure that USB2 is working.

Gparted has its own LiveCD on the website, 80MB, and well worth it! :)

+1 for mzee's thoughts!

GParted will do what you want great, if you'd prefer to do it from within windows Easeus Partition Manager will do the job too.

Thank you all. I will now get the suggested programs and give them a run.
Post back to you later about results.
I was dreading that MCC was faulty, meaning the OS that I have running is corrupted, because I tried to show free space as Green in the Com Management and it wouldn't do that either.
Reason for thought is that about 4-6weeks ago, a mate came rund with a 500GB External and hooked into my com, transferring a few GB of data to my com....after he'd gone I had probs with my com; missing drivers, host IDE Controllers for virtual drives, missing, etc. I tried System Restore and all my restore points were gone.
Eventually I had to do a System repair from the XP Pro OS CD. A virtual reinstall...lengthy process..had to do it twice...didn't replace the IDE Host Controller and I don't know what program that is for, yet.
I'll try G-Parted first. Thanks. Let you know.

mzee..the USB2 is working fine

The Seagate External does not show in BIOS (Setup) but I guess that's because its USB connected and not IDE.
Back to you later

Well I got GParted versions and, also I got EPM.
Haven't used EPM yet and once I'd figured that GParted ISO's weren't going to run from a virtual drive or an optical drive with Windows up and running : )... I rebooted com and got GParted running from bootup....as its meant to do...: ) ..chuckle.
Did the job purrfectly...
Then along came a spider that sat down besider.....attempting to assign a drive letter to one of the Logical Drives (partitions) I had created resulted in my now having a completely blank,unformatted/unallocated space of 931.51GB External HDD....yep : (
New thread...." Totally Deleted Data on HDD-Is Data Recovery possible?"

Having said all that guys, GParted excelled. Cheers
