usb toshiba 80 GB detachable HD not getting mounted, not getting creted any device file

[dd]

Binary package hint: hal

Feisty Fawn U-7.04: password protection in the detachable HD is disabled. When it was enabled I tried it on my laptop (Acer). It was giving the same problem. Then I disabled the password protection from a MSW-XP box, after that I could use it with my laptop. Then I created a ReiserFS partition on it. And is using it with my laptop with the same Feisty Fawn 7.04. With my desktop, again it is giving problem, though password is disabled, and FS is Reiser. The output of 'lsusb' is:

The Primax thing is my USB mouse, that is working properly. The output of dmesg is:

Still having the problem.

But, it is not automounted, as it usually happens with USB devices, neither I can mount it myself, because I don't get any device file added.

[dd (paagol)]

A 512 MB detachable stick (with VFAT) is getting automounted, and the device it is getting attached to is /dev/sdc. The two HD-s are /dev/sda and /dev/sdb.

This toshiba 80 GB detachable HD was first giving the same problem with my Acer laptop, when it was password protection enabled, and then I made it off with an MSW-XP machine, and made the whole thing one single ReiserFS partition. And now it is working fine with the laptop. But, it is not working with the desktop.

Where exactly is the problem?

[dd (paagol)]

Actually, the problem was neither in the desktop machine, nor in the USB HD. It got solved in the most curious of ways. One guy told me to try the HD not in the USB port on the front panel, but on the back of the cabinet, he said he has seen this happen. I did it, and that very moment it got connected and mounted. I don't know why. Maybe the amount of current supplied to the USB port in the front panel was inadequate for this high-speed USB HD. And I browsed the documentation of the motherboard. It is not there too, about any difference in the amount of electricity. But it happened. And maybe, because the current was inadequate, it was taking very very long for 'dmesg' to report the drive and its specification.

Pasting the 'dmesg' portion here, if it is of any help to anybody:

Right, this seems to be an electrical problem then; in your first dmesg outputs there were a lot of bus resets, which usually happen if the device gets into an undefined state (common for brownout).
