    Question Rosewill R2S-B USB enclosure

    I admit I am a Ubuntu noob. I recently installed 10.10 desktop and absolutely LOVE it. I have a lot of command line Solaris experience in a work environment, but have never dealt with new hardware.

    I have a Rosewill R2S-B USB enclosure. Ubuntu does not recognize it. Looking at their website http://rosewill.com/products/1336/productDetail.htm it doesn't even claim Linux support.

    I have googled around about how to mount a USB drive, but it doesn't appear Ubuntu even knows the USB drive is attached to be able to mount it.

    Does anyone have any guidance?

    It's unusual for USB drives not to be automounted when you plug them in, but it happens occasionally. Could be an enclosure firmware issue. Let's see if it's being seen at all. Plug it in, switch it on and then from a terminal:

    Code:
    dmesg | tail
    and...

    Code:
    sudo fdisk -lu
    Also, let's see if we can get the product ID. Useful for googling.

    Code:
    lsusb
    Post those outputs in [code][/code] tags and we can take it from there. You can use the # icon in the message toolbar to wrap the output in code tags.

    Ubuntu should normally take care of all of it.

    Are you sure there's a filesystem on it? If not, please consider which type you want, ext4 for most features and better performance or NTFS for Windows compatibility.

    Try opening a terminal and type
    Code:
    tail -f /var/log/messages
    Now connect or reconnect the enclosure and post the output here.
    What? I'm not allowed to say fsck? Then how is i supposed to help people fix their filesystems?

    Yes, XFS is on it. The drive came from a different external USB 2.0 enclosure that I had hooked up to a buffalo linkstation. The old enclosure died. I bought this new one, popped the drive in it and the linkstation did not detect it. It is certainly possible the drive itself has failed. I will grab a different drive and put it in it and see if it is detected.

    I got NO new lines in the log after reconnecting the device.

    It is like Ubuntu doesn't even know there is a USB drive attached at all.

    Re: Rosewill R2S-B USB enclosure

    Sorry to waste everyone's time.

    I figured out the problem. There is a dip switch for either "BIG" or "JBOD". I had thought from RTFM that "JBOD" was to ONLY be used if you had 2 disks in it and to use "BIG" if you want to mount and treat each of the 2 disks individually or if you only had a single disk.

    Well "BIG" mode didn't work with a NTFS drive and the enclosure plugged into Windows, so I tried "JBOD" just for the heck of it and it was detected. I put back in the XFS drive and it worked in Ubuntu and also in the linkstation.

    Problem solved...sorta.
