This is a known error, and as we speak Elliott Mitchell is hunting
through<br>
kernel and driver code for a solution. Please help him achieve fame
and<br>
fortune (and perhaps impress future employers) by sending him logs.
Also,<br>
please see which USB to IDE chipset is in the bridge in your
external<br>
enclosure. This may show up in /proc/bus/usb/devices , or in dmesg
.<br>
<br>
Note that some of the older enclosures may be incapable of doing
>137GB<br>
drives. This is a separate issue, and perhaps not solvable with
kernel<br>
code repairs, depending on the way the enclosure constructs ATA
commands. <br>
<br>
This is a fairly critical problem to solve, because IDE hotswap is
being<br>
left out of the 2.6 kernel, perhaps indefinitely, according to Alan
Cox.<br>
USB2 or ethernet are the only hotswap alternatives for 2.6 I know of.
<br>
In the interim, do NOT use a USB drive for backups.<br>

I have 3-4 different USB drive enclosures that I can make available, if
that would help the effort. All support drives > 137 G.<br>
<br>
Is this only a USB problem, or also firewire?<br>
