Today I faced with (expected) compatibility issue. I have connected Seagate Go Flex USB storage drive which is 3 Tb (and even report its sector size as 4kb unlike first WD advanced format drives!) but Dune HD Max seen drive as empty.

I expected something like this as HDD obviously formatted with GPT partition table comparing to industrial standard MSDOS partition table. It requires 64bit system to address the range.

But is it ever possible for Dune to support such 2+ Tb drives?

Partition 2 TB + 1 TB may help you at the moment...(as expectet...)

Different 3tb drive & it's internal but check this link http://www.mpcclub.com/forum/showthr...t=25964&page=3 one post up from bottom of that page there is a screenshot of 3tb drive working.

Not sure if any help for your particular drive but maybe worth a look.

Cheers.

Hello Guys,

i´ve got so much trouble with my new 3TB WD HDD.

However, I have the problem that I have auto. DUNE from the HDD with EXT2 have had formart. Now I get the total capacity of the disk: 2200 GB displayed.

How should I proceed to order the HDD to format in NTFS or EXT3 on Dune?

Note: I get the Dune EXT2 appear when I'm using a Notebook on the network drive, I get shown as NTFS file system.

Nice Rgsd.

Good news everyone! 3 Tb drives easy format and use! =) Just download from NMT-200 and run from Dune file menu one of the following utilities on your choise:
dune_service_af_gpt_make_whole_ext3_on_hdd.dsf - searches for an empty (or with one empty partition) HDD, creates GPT table and one EXT3 partitition with "large file" type (1 inode = 1 Mb) on the whole free space;
dune_service_af_gpt_make_sstorage_and_ext3_on_hdd. dsf - searches for an empty (or with one empty partition) HDD, creates GPT table and two partititions, first 2 Gb, marked as "system" for Dune (to store some needed data not in limited by rewrite cycles onboard flashROM), second with "large file" type (1 inode = 1 Mb) on the whole free space left.
Utilities are specially designed for new large HDD and big files, such format gives maximum free space, maximum perfomance and less noise. BUT! If you store a lot of small files on such HDD - all of them will take 1 Mb of space on HDD, even files of 1 byte size - so with such format you will not save free space - you will lose it!

Hahaha wow, the Russians beat me to it.

I was about to point everyone to this post where I created two dsf files with almost the exact same name and purpose.

My 3tb wd drive connected via esata shows up fine on my dune d1. I formatted it on windows 7 as gpt with one partition of 3 tb. The dune shows 2 partitions for it. The first one is empty, but the second one is the actual 3tb partition.
I thinking the first empty partition is due to the required gpt structure.

I also just posted on this in another thread. That extra partition is a Microsoft thing.

I think the extra partition shows that Dune does not fully support the GPT concept. besides that, if I am not mistaken if you have the HDD inside the dune and try to connect it to the computer through the USB connector on the Dune's case, your computer will not see the 3Gb. Or has anyone succeded in getting a computer see the total capcity in an attached Dune with a 3Gb HDD inside?

The Dune understands GPT or else this would not be working at all. If anybody does not fully support the GPT concept, it is Microsoft, with their creation of this hacky Microsoft Reserved Partition which they then hide from the user. The Dune sees it for what it is: an ordinary partition (though of unrecognized type).

Conceivably, the Dune firmware could be updated to recognize this partition type and hide it from the user. But that would be a workaround for a Microsoft issue, not anything to do with Dune's GPT support.

I've never tried to use my Dune as a USB slave so I can't confirm or deny. But even if it doesn't work, that has nothing to do with Dune's GPT support (or lack thereof).
