alpha rt-n firmware releases

[lly]

1. The Iomega 1Tb are external 3.5 disks and have a external power suply;
2. Everything worked for 2 years on a asus 500gp without any problems;

I don't want to say that your HDD is bad, it has some kind of "specific"...

3. The drives work perfectly (same power suply and same usb cables) attached to laptop (either windows or ubuntu)

Does your ubuntu use obsolete 2.6.22 (or older) kernel?

4. the problems started when I switch the 500gp for the RT-N16 with this firmwares (I didn't tried with the original asus firmware)

Well, but we neither can't switch to newer kernel, nor completed usb backport yet

P.S. Mine hitachi usb hdd works well with RT-N16...
