1 Hi there,
2
3 I rejoin the list after 5-6 years. Was able to fix most of the things myself
4 but this one has me totally bowled over.
5
6 I have an IDE disk enclosure (can house 2 disks per IDE channel, a total of
7 4 currently plugged in) which makes IDE disks available to the main computer
8 via 2x USB 2.0 connection (One USB 2.0 port connected to IDE adapter).
9 The problem I have is that the computer is able to see only 1 IDE disk per
10 channel. At a time, as a result, my server can only see 2 disks instead of 4
11 connected, one disk per channel only.
12
13 I have tried all possible combinations of jumpers (master/slave,
14 cable-select, force-slave-present) for each pair.
15
16 Interestingly - Windows XP / YetAnotherReiserFS GUI is able to see/read all
17 4 (2 pairs) disks so I think it is something that needs fixing in Linux
18 kernel/drivers and the enclosure box is not the source of problem.
19 I confirm individual disks are fine as well.
20 I am currently running Linux 2.6.27-gentoo-r8.
21
22 Has anyone else encountered this problem before ? /proc/config.gz is also
23 attached.
24
25 Thanks in advance,
26 Rohit
