Hi,
I have an old quickdrive using the shuttle epat plus 635d chip. I am
able to install the modules with no reported problems, but the the data
is messed up (including the partition table) (see examples further
down).
I have tried this with two different disks, both known to work, and got
the same results.
When I tried to write a new parition table, it did so without errors,
but then could not read it. When trying to create a filesystem on the
disk, the system hangs (probably due to it not reading the partition
info correctly).
I am running kernel 2.4.12
dmesg information:
pda: epat 1.02, Shuttle EPAT chip c6 at 0x378, mode 2 (8-bit), delay 1
pda: SAOSWNG WN3236, master, 1426312800 blocks [696441M],
(4698/528/575), fixed media
pda: pda1 pda2 pda3 pda4
This is actually a SAMSUNG WN321620A, not a SAOSWNG WN3236 as printed
above.
With the other disk, it returns 0aztor "92670W2, Which should be a
maxtor 90650U2
result of dd -if=/dev/pda -count=50:

I think the end bit should be roughly "setup cannot continue error
loading operating system. system cannot continue.
Interestingly, there doesn't seem to be any pattern to which characters
are altered. It seems to be completely random.
I would really like to hear some advice on this problem. I do not know
what to try next. If anyone has found a similar problem and not been
able to fix it, I would also Like to know.
Also, If anyone has any advice about getting technical data from
manufacturers (in case nobody is able to solve the problem), then this
may also be useful.
I look forward to hearing a response. Thanks in advance.
