Problems with USB mounted external HDD and NTFS

[richie141]

Hello.
So I have a Raspberry Pi running "2013-09-25-wheezy-raspbian". I have installed all the NFS bits and followed the guide. My HDD is formatted to NTFS and all the ntfs drivers are installed on my Raspberry Pi.

Now I know that the system works. I had a 8gb memory stick formatted in NTFS attached to a USB hub and I could stream the two movies and a few tv shows on the pc with XBMCBuntu and a Raspberry Pi with OPENelec on it. No problems. But when I swapped the USB Stick with a external 2.5 external HDD thats in a enclosure with USB 3 attached to the usb Hub. I mounted it and thats all fine.
Both XBMC machines can see the NFS. They can even set it up and download all the show information. But when I click on a movie or show both machines freeze then come up saying no remote connection. Some times I can watch a little bit of a show before it does the same thing. When I go back onto the Raspberry Pi NFS server the USB HDD under 'sudo fdisk -l" shows the the HDD has gone from /dev/sda1 to /dev/sdb1 etc. I then re-mount the device and it does the same thing over and over. But no errors come up on the screen.

Has anyone heard of this before? The reason I use NTFS is so that I can swap all my Movies from a PC in a different house.

The strangest part is when I used the usb Stick with NTFS format it worked like a dream. Only when swapping to a hard drive did it go wrong.

My HDD enclosure is this … http://www.novatech.co.uk/products/comp ... 3-gy..html "Novatech 2.5" Tool Free SATA HDD/SSD Enclosure USB 3.0"

I also Have a Novatech USB hub.

Any help is much appreciated.

I have had all manner of issues when reading a NTFS hard disk. I could mount it and read some files, but other files were not accessible. This issue has to do with the size of the HDD and the number of files. In your case I suspect that the NTFS driver is croaking and the OS reassigns a new device. I have no solution except to use ext4.

Ok. I guess I will have to try ext4 then. All my files are on windows 8. Is there a easy way to format to ext4 and get the movies across to a hard drive thats EXT4 on windows 8?
So the problem will more likely be because of NTFS hdd than the set up?
