Problems with a docking station

[Niels]

Hi people,

I'm not quite sure were this problem belongs...

I have an AGK hard disk docking station, like this:

http://www.agknordic.com/index.php?side_id=387

It works fine, as in I can transfer files. The problem is that it apparently
disconnects disks forcefully. If i put one disk in, it gets mounted fine
as, say, sdg1. But if I then put in another disk, the first one is
disconnected, and they are both discovered by the system, as sdg1 and sdh1.

This is obviously not so good for the file systems.

One time I got this:

usb 2-2.2.5: USB disconnect, address 13
EXT3-fs error (device sdg1): ext3_find_entry: reading directory #2 offset 0

Yes, I know it's an old kernel. I've been having printer problems with 35
and 36. Could the above problem possibly be solved in a newer release, or
is this simply poor hardware design?


Thanks,
Niels
