Ive had bad experiences in the past with NTFS on the raspberry pi that's why I use ext4 all the time now.
When using NTFS the pi runs alot hotter than it does using ext4 when writing to the external drive. I've had it crash several times using NTFS because of this when trying to copy stuff over.
I have now solved the problem by dual booting my computer so that I have Linux on it as well.
I have formatted the drive under Linux with ext4 then copied my stuff over to the drive that way.
Everything seems to have gone smoothly and is now back up and running.
I just wonder if the pi was not quite capable enough for my to transfer my 760gb of media over samba lol.
Probably my fault pushing it to much.
