Mageia and NTFS disk

[Shlomo Solomon]

I'm about to format my new 4Tb drive as Ext4, but before I do, I
wanted to see how it shows up "out-of-the-box" and got some strange
results. I'm pretty sure formatting as Ext4 will solve this, but I'm
curious if anyone can explain the following:

I mounted the drive and I see:
[solomon at shlomo1 ~]$ df |grep Seagate
/dev/sdj1 3.7T  203M 3.7T 1% /run/media/solomon/Seagate Expansion Drive



[root at shlomo1 solomon]# fdisk /dev/sdj

Welcome to fdisk (util-linux 2.24.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Command (m for help): p
Disk /dev/sdj: 3.7 TiB, 4000787025920 bytes, 976754645 sectors
Units: sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0xc64aae83

Device    Boot Start       End     Blocks  Id System
/dev/sdj1       2048 976752639 3907002368   7 HPFS/NTFS/exFAT



But, when I run the "Manage Disk Partitions" utility in Mageia's
Control Center I can see 1 "small" NTFS partition and another 1.9Tb of
un-allocated space for a total of only about 60% of the disk:

Device: sdj1
Volume label: Seagate_Expansion_Drive
DOS drive letter: C (just a guess)
Type: NTFS-3G
Size: 465GB (12%)

Empty
Size: 1.9TB (54%)
Cylinder 60800 to 328149

After hitting the "clear all" button I see more or less the proper size:
Device: sdj
Size: 3.6TB
Name: NA4KTWL4


As I wrote, I'm quite sure formatting EXT4 will solve this, but WTF?
