It's formatted with NTFS ... It would be nice to format it with ext4 and put in on that old Linux system ... and it's a ~2TiB Hard Drive --whatever that means for fdisk, Linux, etc. So, let's see how troublesome that may be.
#uname -r |awk -F '-' '{print $1}'
2.6.32
2.6.32 should be allright according to this
Alternatively some sort of result on
#grep ext4 /etc/fstabwould be a "good to go" signal as well.
Anyways, let's see how the system sees the 'new' drive
#lshw -C disk

Delete old partition(s) and put one nice large partition to it. Thinking fdisk? Don't! use parted.

OK, no more partitions and the partition table is of type gpt.
Let 's create one large 2TB partition.

Let 's see what fdisk sees.
#fdisk /dev/sdb

OK, let's format the partition to ext4.

Reclaim the 5%.
#tune2fs -m 0 /dev/sdb1 tune2fs 1.41.11 (14-Mar-2010) Setting reserved blocks percentage to 0% (0 blocks)
Mount and test
#mkdir /green #mount /dev/sdb1 /green #df -h |grep green /dev/sdb1 1.8T 196M 1.8T 1% /green
Told him 0% reserved space, I guess it will not accept less than 1% for the system ... anyways ...
Put on fstab
#echo "/dev/sdb1 /green ext4 defaults 0 2" >> /etc/fstab
Done!
