Hi,

I am pretty new to linux and have the following problem: when I try to mount a USB HDD linux does not mount it. Strange is that it mounts another HDD using the same USB case. This is what I get as a message (I turned off and on the HDD a few times):

This is what I get when I mount the other one:

apart from the CHKDSK problem everything is fine. I do not understand why one HDD is mounted without problems and the other one cannot. Any suggestions?

Thanks a lot.

well i would assume that these devices are usb2.0,but you're only loading them using one of the usb1.1 modules. run a "modprobe ehci_hcd" to load the usb2 driver and try again. you might want to "rmmod ohci_hcd" to make sure that only the 2.0 driver can be used.
