    USB hard disk problem


    Hello,

    I have the following problem with a new external USB hard disk when inserting (in an Ubuntu 8.10) and so I cannot moun it.

    ...

    Is the hard disk already damaged ?
    Can I force some mount and reformat ?

    Thanks for info / resolution about this.

    Bye,

    There was a time when the kernel had a problem with the ATA devices, being slow and all. Don't know if this is the cause of your problem.
    USB connections on the backsite of your computer might give a better result.
    Does your drive have power of its own? Otherwise maybe you need to use 2 ports (1 for signal and power, the second cable for power only) in order to have enough power on the drive because USB 1,1 is limited.

    Indeed the device has two USB connectors and power on its own.
    As you suggested, I connect both plugs : works slightly better but the hard disk still freeze after few seconds ending with same problems I mentionned in my first email.

    I suspect maybe this is a simple hardware problem ?
    My vendor confirms I'm able to obtain a replacement so I'll go this way for a (hopefully) solution.
