Hello I am thinking of putting a 12 TB HDD to the Dune Pro Vison. Who knows if they will accept this unit or have limitations? Thanks
-
It should be OK. Up to and including 16TB should work.
-
Gracias...
-
self installed... 16 - 18 TB works fine...

I tried to use an internal sata disk of 18 TB (Seagate X18) but was not readable or formattable by Dune (error creating partition) so I had to do a partition of 15,99 TB (GPT) so I am asking how are you using the 18 TB drive that you wrote is OK for DuneHD Pro Vision 4K: smaller partition?
I tried to do partition of 16 TB (GPT) but Aomei Partition Assistant gives error and crash chosing ext4, instead 15,99 TB works: why? Aomei can do bigger partition chosing NTFS but with a partition of 18 TB (the all disk) the drive is not readable by Dune (ask to format it but if you do gives error creating partition).
Is ext4 the best file system for such big disks for DuneHD Pro Vision 4K using SMB to access data from PC?
Is the problem due to the choice of 512 or 4096 byte per sector? Which one is the correct choice?
Thank you.
-
Dune does not support 4K Logical Sectors only 512 bytes.
-
hi,
I always formatting via the PC with NTFS... not over the Dune
-
Hey, I have the same problem like "campus". HDD - 18 TB (Seagate X18). After formatting on PC Win10 to NTFS 18TB, DUNE PRO 4K PLUS II doesn't read them correctly. So I made a partition (as advised by "campus") a little below 16TB (Dune shows 16200GB) - and Dune works OK. Alas, 2TB is wasted. I think, 16TB must be a NTFS limit for Dune (and nobody knows why; last actualization of Dune system was in year 2020).
-
at the end I solved this way:
only one partition of size 18 TB but created and formatted (NTFS) by Windows 10 Pro "Disk Management" in this case the dune can read it. If I do the same by the software Aomei dune can not read the disk do not know why. Please try this way and let us know if it works even for you.
-
android did not really implement NTFS. They just made it work assuming fixed values for multiple variables which just are ignored. Also the 2nd FAT table is never checked for actual consistency.

Hey Campus! Before my last post, I just formatted my HDD - 18 TB (Seagate X18) by Windows 10 Pro "Disk Management" with default allocation unit to the one NTFS partition 18TB. And after copying on hdd same directories and files (on my PC) - Dune did not read them correctly. So I was forced to reduce a capacity by creating 16TB partition, and now all is OK with Dune. But may be problem is with allocation unit, which I left as default? May be I should choise 512K?
-
default was ok for me: 512 byte per sector and 16 sectors per cluster. What read problems do you have? I am using UGREEN SATA USB 3.0 adapter from amazon 24,99 eur

Hey! After many many trials I found a max partition value tolerated by DUNE Pro 4K Plus II.
It is 16.770.000MB (Dune shows 17,6TB and Win Explorer shows 15,9TB).
All allocations was realized on my PC Win10Pro with NTFS parameter and default allocation unit. Next was tested on my Dune (if partition was to big DUNE did not recognize the disk).
Now, only 396.333MB (0,4TB) is wasted, so I create in this space a second v. small disc partition - 0,4TB.
Campus! Dune Pro 4K Plus II has his own 3.5 disc rack, so I do not need any adapter.
-
That limit makes a lot of sense to me. It is a 32-bit register counter for 4Kbyte sectors.
-
please try partition (only one 18 TB) and format by Windows 10 pro "Disk Management" choosing 8K byte for cluster (or allocation unit that is same thing) dimension.
Your dune model is older than mine (Dune HD Pro Vision 4K) but maybe you can get only one partition (18 TB) that the dune can read chosing 8K byte size of cluster. Is your dune firmware updated?
Of course even my Dune has an internal SATA slot. The Ugreen SATA-USB adapter I suggested is for connection of the disk TO THE PC not to the dune.
-
Campus, Nice Monkey, thx for your advices, but all tests I realized was without removing my erlier recorded data (about 10,5TB). I was only increasing and decreasing the size of a volume by Win10Pro Disk Management. Copying such big data takes about 1 day, so I don't want to do it now.
I do not know what is my cluster dimension (how to check this?) because I left parameter as default (I assumpted, that the Windows should choise the right size). So thx, but may be I try to test 8K cluster a little bit later.
PS.
My last actualisation is - 201027_1259_r15 (27 october of 2000 year). There is no more.
My PC adapter for 3.5 disc is ICY BOX IB-117-U31 with USB 3.1(gen2) but I think it doesn't matter.
-
I would be extremely surprised if the cluster size matters.
-
Hey!
I found unit allocation size of my already formatted disk (Seagate18TB):
Type - NTFS,
Allocation Unit Size - 8192.
Other system possibilities of Allocation Unit Sizes: 4096, 8192 (Default), 16K, 32K, 64K, 128K, 256K, 512K, 1024K, 2048K.
So, chosing size 8K is impossible.
-
8K=8*1024=8192
-
Of course, sorry.

Hallo I have a "Dune HD PRO Vision 4K Solo" with inside (SATA 3.5" internal slot) a Seagate 18 TB X18 and I connect it, to load files, to my Windows 10 Pro notebook PC by SMB (ethernet LAN 1 Gbps). What do you suggest as file system to format the X18 and why? Which is better for files and data reliability and integrity? How (by which software) is better to format the disk? Dune can not format it (it gives error: probably 18 TB is too big for today dune format app. My firmware version is "211224_0317_r17"). Please explain in a detailed techical way. What file system do you adopt? I am using NTFS now but I am wondering if EXT4 or EXT3 can be better (with NTFS some files disappeared in one occasion; this time I solved by Windows Chkdsk that repaired the file system connecting HDD to my PC by USB; but I have to say that I had a problem (previously explained in this forum) even with EXT4).
Thank you very much.
-
EXT3 has a 32 TByte file limit but EXT4 has not. It is newer and better anyway. So the choice is NTFS or EXT4.
-
OK the choice is NTFS or EXT4 but please explain the differences between these 2 choices and which software is the best by a Windows 10 Pro notebook PC to format in EXT4 and to access to a EXT4 volume. I am using a Ugreen SATA III-USB 3.0 adapter to connect the 18 TB SATA disk to PC.
Is NTFS implemented in a perfect way (expecially for files integrity) by Dune HD Pro Vision 4K Solo current firmware "211224_0317_r17"?
-
Hey again. As I once read on Dune pages, only EXT format makes possible connection to hdd filles via WiFi (SAMBA, NFS, UPnP) from for example your PC. But EXT format is dedicated to Linux systems and to read them via your Ugreen adapter in Windows you need install an extra program (driver) e.g - Ext2 File System Driver for Windows. Why? Because Windows system do not like and do not support Linux system ;-)
So, I don't use EXT and WiFi and I am using ICYBOX hdd adapter. It is much quicker method to copy data files.

Hi guys
I am contemplating to buy HDD for my Pro Solo 4K
Is the one below OK?
Western Digital 18TB WD Red Pro NAS Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5" - WD181KFGX
The official website mentions low RMP (ex 4500) but here it is 7200?
Wondering if this is OK. Thank you
-
It will be OK. Low RPM is just a recommendation, these drives are usually quieter and cheaper.
-
I noticed something very strange:
My 4TB USB SSD (SanDisk Extreme Pro) cannot be read by the Dune. When I format it with the Dune everything seems fine but as soon as I connect it to a Windows PC and then re-connect it to the Dune it says CAN NOT ACCESS. On Windows i can access those files without a problem.
I have no problem with 2TB USB SSDs. It seems Windows does something to my drive when connecting / initializing it.
I tried different formatting options / file systems. Doesn't help. I would love to make my 4TB drive work for plug and play on the Dune.
Please help! Thanks!

Quick question can I use a NAS drive in the internal bay?
-
Yes. Any 3.5 inch drive.
