[SOLVED] Micron USA Technology Corp. JM20337 Hi-Speed USB

I've got an old 250 GB Maxtor disk which has one ext3 partition on it and I want to get some files from it using a JMicron USA Technology Corp. JM20337 Hi-Speed USB to SATA & PATA Combo Bridge. I plug in the usb device and attach my HD and then plug the HD into an external power supply. Then nothing happens after that lsusb gives

Bus 006 Device 001: ID 1d6b:0001 
Bus 008 Device 001: ID 1d6b:0001

and dmesg gives

how do I mount the partition on the disk?

Re: [SOLVED] Micron USA Technology Corp. JM20337 Hi-Speed USB

It seems it didn't detect anything connected at the other end .... maybe something to do with "usb 2-3: reset high speed USB device using ehci_hcd and address 2"
You should expect to see something like

Note the "sdb: sdb1 sdb2" line where it detects the partitions.

Re: [SOLVED] Micron USA Technology Corp. JM20337 Hi-Speed USB

sd 8:0:0:0: [sdg] Attached SCSI disk

there's your device name.
So, assuming you want the first partition:

mkdir /mnt/getstuff
mount /dev/sdg1 /mnt/getstuff

Tada--mounted. If it doesn't like that, try giving an FS type (mount -t ext3 /dev...). But, that's usually not an issue for ext3.

Now, there is one odd thing...I'm used to seeing a line with partitions just before the "Attached SCSI disk" line, like so:

sdg: sdg1 sdg2

But, it could be a new kernel thing...

If you don't have partitions in /dev, then something's wrong.

If you have hal running, and a nice GUI environment, are any apps that normally see removable drives not showing anything (FI, Dolphin)?

Re: [SOLVED] Micron USA Technology Corp. JM20337 Hi-Speed USB

I can see that you have sdd: sdd1 sdd2

but my disk has only one partition.

Re: [SOLVED] Micron USA Technology Corp. JM20337 Hi-Speed USB

Then at least sdx: sdx1 should show up. Try fdisk -l as root and see if anything besides your fixed disk shows up.

I think you need to power it up before you plug in the USB cable. At least, that's what seems to have worked for me today.
