Many thanks for the reply
I also had the same problems trying to connect a hdd 3t seagate to the usb port of DNS 320l ... because it is not able to read partitions on a pen drive whether it is exfat = fat64 , exfat3 , exfat4 , ntfs with more than 2t, Etc ... in summary and a very bad, terrible defect that was not cured by the manufacturer and will never be fixed. Because it is a physical limitation of DNS 320l.
I have performed a lot of tests with seagate 3t hdd, seagate 4t hdd, and all were in vao even changing the size of the clusters as informed above by the forum colleague did not have success ...
The fault is the following ...
1- You connect your 3T hdd drive to the DNS 320L usb (2.0) primitive port -
2- The DNS 320l device ... connects to the usb and an orange / red light rises ... ie (saying that it did not recognize the partition) so you can DELETE ALL YOUR VICE VERSA BACKUP DATA. OR NOT, RS ... BETTER NOT.
3- If you persist, click and hold the button on the 320l -USB DNS device and hold until the light goes out ... it switches off and the orange / red light ... goes off then
4- Hold the USB button again, on the DNS 320l device it will appear BLUE and you will have a momentary joy ... because even Blue it is NOT ABLE TO RECOGNIZE THE DEVICE CONNECTED to usb 2.0 of DNS 320l.
That is ... exfat = (fat64), exfat3 , exfat4 , ntfs , fat32 with more than 2Tib Do not work on the Usb port of the 320l DNS device. unfortunately.
And even those that work are limited the configurations mentioned above ... that are them ...:
"" You need to setup the format with the size of both sectors and clusters otherwise it defaults to 2TB maximum. The list below gives the necessary information:
2 TiB (with 512 byte sectors)
8 TiB (with 2 KiB sectors and 32 KiB clusters)
16 TiB (with 4 KiB sectors and 64 KiB clusters)
Ps: The Usb Port of the Dns 320l Device Is not compatible with almost any partition ... even if it is small of 4 8 16 32 64Gb. Recovers only what is written to NTFS (which ends with the life of the Pendrive in up to 75%)
And Fat32 (which is unpopular to record and read files over 4Gb or can not see good quality movies because fat32 does not.)
NOT SUPPORTED EXFAT = FAT64 IN SOME WAY IN PEN DRIVERS.
In short the usb port of Dns 320l and Obsolete .. almost useless, for enthusiasts and a real shame the USb (2.0) port of the device
Use this information to correctly format a USB device because if you do not you will have problems. It can appear to format with the incorrect settings but most Linux based equipment will not 'see' it or mount it. ""
Then I believe that this information is useful to all those who seek the limitations or which ones: fat, size, number of clusters the DNS device 320l d'link and able to read and record through the usb port. Usb 2.0.
My tests were conducted on 06/2017 with the fix Firmware:
1.09B06
Hardware: DNS-320L A1 / A2 / A3
DNS-320LW A1 / A2
