ok so I deleted tons of old stuff I'll never need again and I formatted my 2tb goflex drive to ext3 using gparted.
Then I had to use ext2volume manager to be able to see the ext3 drive on my windows 7.
Then I moved about a 800gigs of data back onto it overnight.
Plugged into windows, I can read/write to the drive from my computer now.
But when I have it plugged into the router, I only have read access and I cannot write to it. It keeps saying I need permission to write to the drive.
If i reboot the router, I lose access to the drive completely. I have to eject the hdd then mount it again to gain read access again without write.
I tried plugging in a ntfs drive and it's working totally fine. and this ext3 drive was perfectly fine when it was ntfs before I formatted to ext3.
So what could be the problem? other people seem to be using ext3 drives with Merlin build.
Samba is set to share without account and It has r/w blacked in.
