Large files problem on External USB drive (NTFS)

[Nick N.]

Hi 

Viva (KN-1910), 2TB extrenal USB drive NTFS, 3.7.4

I have acronis backup file, 350Gb. I trying:

1. Copy to router with external HDD - very SLOW, after 150GB writing speed down to 1-2 MB/s

2. Open TIB file from router with external HDD in Acronis Tru Image not working

3. Copy to PC with external HDD is ok, writing speed is stable, 30-40 MB/s

4. Open TIB file from PC with external HDD via network in Acronis Tru Image working fine

Small size files (less then 150GB) is working fine. Check please

All test maked from Notebook, external HDD was connected to Keenetic Viva or PC. Viva did not working stable with large files

Find in log:

tntfs error (device sda1, pid 30929): ntfs_write_end(): Write failed (orig copied 2664, len 4096, actual copied 0).

Big files not copied via SMB to any hdd. I testes another HDD on 500GB and exFat 

[bora ozver]

can you resolve your issue with using exFat?

[Nick N.]

No. ExFat working as NTFS

Tested on two HDDs, 500GB and 2TB

generally formatting the disks in NTFS does not allow you to write files larger than 4 Gb, format the disk connected to the modem / router and make it GPT, you will see that all limits will disappear, as well as errors. It is recommended to use GPT formatted disks for capacities over 2 Tb, otherwise use Linux ext4 formatting. (for everyone)

P.S. The disk over 2 Tb GPT is mandatory, otherwise NTFS will not show you beyond 2 Tb if you do not make it GPT, but it also works great on 1 Tb disks. (Less than 1 Really makes little sense but if you don't want to use Linux ext4 that's fine anyway!)

I have GPT disk and NTFS partition. From PC all working fine, from router working fine for files less then 100GB

FAT32 does not allow you to write files larger than 4 Gb, it's not NTFS

100Gb? I hope you are not using Windows 32, otherwise it is not explained, because these are the specifications of NTFS on Windows 64.
