I have found what I think is a bug.

I'm retiring my DNS-323 and going to a DNS-345. In order to transfer the data I thought I'd mount a USB drive, copy to that, then move the drives to the new NAS unit, format, copy data, done.

Problem is my Toshiba USB drive will not mount. I can get it to mount on my Tomato router, however. I have tried NTFS, EXT3, and also changing it from MBR to GPT (with the appropriate Alt-F package installed for GPT). I am also doing a full format for NTFS vs. a Quick Format to do one more attempt to make this work.

usb-storage 1-1:1.0: USB Mass Storage device detected

scsi4 : usb-storage 1-1:1.0

usb 1-1: reset high-speed USB device number 4 using orion-ehci

usb 1-1: USB disconnect, device number 4

scsi 4:0:0:0: Device offlined - not ready after error recovery

I found a thread on the net and I think this makes sense as the reason things don't work. I just don't know how to test it. This is the thread -> https://bbs.archlinux.org/viewtopic.php?id=125831

Basically, the kernel is only waiting 1 second before saying it can't read from the drive. The default value for the kernel 3.3 should be "5", but for 0.1RC4 (what I'm running) the value is "1". I looked in release notes for RC5 and I see no mention of this, thus I have not done the upgrade.

If I can't make this work with the DNS-323 I'll be forced to copy 1TB over the network to my Windows machine with the Toshiba drive attached, then plug into the DNS-345 which recognizes the drive fine.

The system log time-stamps the kernel log, which might reveal if the 1/5 seconds you talk bellow happens or not.

I have no kernel patches applied at this level, and Alt-F don't use udev, it uses mdev.

If your usb drive is externally powered, apply power to it and wait a few (10) seconds for it to spin up, then connect the USB cable; if the drive is USB powered and this is indeed a timing issue, there is little hope. You can try powering up the nas with the USB drive already powered up and usb attached... if it is really a USB drive spin-up timing issue.

If I can't make this work with the DNS-323 I'll be forced to copy 1TB over the network to my Windows machine with the Toshiba drive attached, then plug into the DNS-345 which recognizes the drive fine.

You might be surprised, but transferring though the network is not going to be slower than using the USB drive... the only inconvenient will be to have the PC powered up while it happens.
