Hello,
I'm having trouble accessing a 3TB external drive. I have an IcyBox IB-351 series (IB-351StU3-B) external USB SATA enclosures. When I connect a 3TB external drive to my server (Ubuntu Server 10.04) and try to access it, it hangs completely. For example, running parted, mounting a partition, or running badblocks. It just hangs and I usually have to kill -9 the process.
It works just fine when I use the 750GB drive in the enclosure. The enclosure and drive work just fine with a 3TB drive when hooked up to a Windows PC (Server 2008R2 64-bit). I have tried on two different Ubuntu servers with completely different chipsets, and I see the same results.
I've only used prebuilt kernel binaries from Ubuntu, including some backports. I've tried: 3.0.0-12, 2.6.32-30, 2.6.32-34, and 2.6.38-11. Results were the same on all versions. All were 64-bit.
Usually when I connect the external drive, I see something like this in dmesg:

"unknown partition table" is expected, it's a new drive.
The sector that it complains about is not always the same, but is usually within that rough vicinity. It is always a >32-bit number.
lsusb shows:

Device ID 1234:5678 seems wrong to me, but that's how it shows up on both boxes. However, this is also how it shows up when I have a *working* 750G drive installed, so I'm not sure how relevant this is.
"lsusb | grep PCI" on the two servers I've tried this on shows:

Which looks to me like completely different USB chipsets.
lsusb verbose output on the device shows the following:

Any ideas as to what I can do to make this work?
Thanks,
