Public bug reported: I'm having a problem with a SATA disk connected to a USB adapter. The disk is detected and its partitions mounted but after I use it for a few seconds to minutes the adapter disappears and dmesg lists errors. If I don't use the disk it stays healthy but running 'sudo cat /dev/sdb5 > /dev/null' consistently causes a failure within a minute. The disk works well connected to the internal slot of the same machine and the adapter works well with a 40GB IDE disk I have on hand.
I looked at a similar looking bug, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1012291 and booted a kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2.27-precise/ which was reported as Linux tb201 3.2.27-030227-generic #201208101235 SMP Fri Aug 10 16:36:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux [disk] Crucial m4 SSD 2.5 256GB [sata-usb-adapter] Sabrent USB 2.0 to IDE/SATA Cable for 2.5-Inch/ 3.5-Inch / 5.25-Inch Drive with Power Adapter http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=2329300 lsusb describes it as ID 152d:2338 JMicron Technology Corp. / JMicron USA Technology Corp.
