My old computer died, and I got a new one, and now I'm working on recovering documents from the old hard drive. As the new comptuer has SATA (and the old one had IDE), I needed to borrow a USB-IDE adapter to recover the drive.
Because I can't seem to find any documentation about the adapter on the web, I'm going to post a tip here about making it work.
The adapter is a JMicron JM20337 adapter. It shows in lsusb as
Bus 001 Device 002: ID 152d:2338 JMicron Technology Corp. / JMicron USA Technology Corp. JM20337 Hi-Speed USB to SATA & PATA Combo Bridge
and it shows in dmesg as:
usb 1-1: new high speed USB device using ehci_hcd and address 2 usb 1-1: New USB device found, idVendor=152d, idProduct=2338 usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=5 usb 1-1: Product: USB to ATA/ATAPI Bridge usb 1-1: Manufacturer: JMicron usb 1-1: SerialNumber: 152D203380B6 usb 1-1: configuration #1 chosen from 1 choice Initializing USB Mass Storage driver... scsi0 : SCSI emulation for USB Mass Storage devices usbcore: registered new interface driver usb-storage USB Mass Storage support registered. usb-storage: device found at 2 usb-storage: waiting for device to settle before scanning
It's still waiting for the device to settle, as I write this, becuase I haven't turned on power to the drive yet. When I first connected it last night (with the drive attached) and turned it on, I got the message:
scsi 4:0:0:0: Direct-Access PQ: 0 ANSI: 2 CCS sd 4:0:0:0: [sdb] Attached SCSI disk
No partition table, and if I tried to
dd if=/dev/sdb (for example to
try and recover the partition table), I got a zero length file.
After some failed googling and experimentation, I discovered that the drive has to be jumpered as an IDE slave. (Not a master, and cable select won't work.)
Then I get the partitions, and more information about the drive

You may also need to plug the USB cable in to the computer after turning on power to the disk for things to work properly. (If you plugged in the USB cable first, you can just unplug it and replug it.)
