TomatoUSB

How can I make transmission to download directly on HDD and not on /tmp/mnt first? Thank you.

Set your 'download-dir' to where you want it to download. If you have 'incomplete-dir-enabled' then also set 'incomplete-dir' to somewhere on hdd.

I have set /tmp/mnt/sda1
But if I`m trying to set anyting else, transmission gui is nbot working.

Traditionally the /mnt directory is exactly that. In tomato however, /mnt is a symlink to /tmp/mnt, becaues of the nature of tomato's readonly filesystem.
Harddrive DO mount to /tmp/mnt, so long as they are correctly formated.
I have a harddrive that is mounted to /tmp/mnt/storage. When I formatted it, I called it 'storage'.
Yes the directory is /tmp/mnt/storage, but you must understand that this is a symlink to the harddrive, so my stuff is not stored in ram.
What file system are you using? It may be correctly mounted already. If not, you need to format it correctly. Tomato has the ability to automount formatted disks to /tmp/mnt.
You would not try to use /dev/sda1, as you mentioned in linksysinfo. That is not where harddrives mount to.

Try running 'df -h'. If your harddrives is mounted, you will see /tmp/mnt/sda1 as your harddrive size.

Using mount I`m getting this:

rootfs on / type rootfs (rw)
/dev/root on / type squashfs (ro)
proc on /proc type proc (rw)
tmpfs on /tmp type tmpfs (rw)
devfs on /dev type tmpfs (rw,noatime)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/sda1 on /tmp/mnt/sda1 type ext3 (rw,nodev,noatime,data=ordered)

and using df -h

When I had n56U and using padavan, on hdd I had .incomplete folder and some others. With tomato I don`t have nothing on HDD besides completed torrents. And if for example I`m at 40% downloading and I must restart router, my download start from 0% thats why I want to download directly to HDD and not first to ram and after complete to HDD.
