I am pretty sure this is hardware problem. Check that it works under
other OS and make sure the cablings and USB2IDE adapters are OK.
1. Which kernel modules are needed (and which are to be avoided) for
to connect an external USB hard drive to the system successfully?
With a USB2IDE adapter plugged into a 1TB IDE drive running on one of my
lenny box, lsmod gives me -
ehci_hcd 28428 0
uhci_hcd 18672 0
usbcore 118160 8
usb_storage,rndis_host,cdc_ether,usbnet,usbhid,ehci_hcd,uhci_hcd
usb_storage 75936 3
scsi_mod 129356 3 sd_mod,usb_storage,libata
3. What should the /etc/fstab look like for which kernel version?
/dev/sdb2 /mnt/extras ext3 defaults,errors=remount-ro 0 0
An internal 250GB IDE disk is populated at boot time in /dev/ using
either sd_mod or scsi_mod (Not too sure on this one).
