Readynas 4200 and 3TB on USB cradle only 746/801 GB...HELP
Hello...
I have a 4200 here that i need to run with a USB attached 3tb Seagate drive...
It shows me 746 gb availalabe and i am able to format that as well...
But i can't get it to see the full size...
smartctl sees the whole cpacity, but fdisk is not able to get it...
I guess it has something todo with the early version of fdisk that does not know GPT...
But somehow it must be possible...
OS is newest version x.30 and i tried to load parted over ssh but it wont work...
Any one did this before?!
THX!!!!

It might be a limitation of the USB cradle. I have an older USB-2 sata adapter that is limited to 2 TB drives.
But you can't use fdisk for this - it doesn't support gpt. You want sgdisk.
Hello...
Thx for your response...
I already checked the cradle and it supports up to 4 TB according to the tech support...
Will take a look at sgdisk...
Can you make a litte suggestion how to use?!
Havent heard about that yet...
EDIT: Played around with it but it also just shows me the 746.5 GiB
And somehow it seems that it is not writing the info to the drive...everytime i do the commands it does the same output...
Thx!!
Hello...Checked around with that tool sgdisk
Here the output that it gives me with the 3TB drive:
