Why does Win XP 64 see partitions incorrectly???

Why does win xp 64 pro, see an extend linux swap partition as a primary
partition??

.. . . If it works ...

Perhaps because xp x64 can't correctly recognize the
partition identification and just happens to show it as primary?

I agree - my Linux Partitions was always displaying as 'Unrecognized', I
don't remember what color the Patition Manager used as designator, but it is
probable that it will assume it is a primary since there is nothing else to
go by.

This machine happens to be away for repairs at the moment so I cannot check.

Ahh - and I forgot, you cannot put any data onto an Extended partition, you
can only use it to create Logical Drives (With a drive letter, in Windows)
any partition the system finds has to originate from at least one primary
partition, and the system cannot make guesses - so, not knowing, primary it
is!

My best guess!

And these two proggies might come in handy for R/W Linux partitions from
XP/Vista x64:
"Ext2 Installable File System For Windows"
http://www.fs-driver.org/
and for Read Only:
"Freeware Linux Reader for Windows"
http://www.diskinternals.com/linux-reader/
I could not determine whether this last utility is x64 compatible or not.

Hello,
Windows should recognize the partition by the "partition type" read from
the partition table.
The partition table contains 4 entries and in one of those entries is the
partition type field which is what tells the OS what the partition is.
I have also seen Partition Type called "System ID"
You would have to dump the partition table and read the four entries to see
what is listed in the Extended partition and see if there is what Linux has
placed in there.
There are quite few different partition types
Thanks,
Darrell Gorter[MSFT]

True, Darrell - you can definitely find ways to read the ID's, but in my
experience Windows Partition Manager won't tell you?

Hello,
It should, but sometimes there is more data in the partition table that it
expects.
It also would be good to know what the partition type is, to ensure that we
are not seeing a case where are partition it not be identified properly or
the data in the table is corrupted somehow.

We shouldn't be seeing this in a logical drive in any case anyway, so we
are reading more from the partition table than we should.
Since the partition table is supposed to be limited to 4 entries those
entries are the first three primary partitions and the extended one.
Where are we reading the information for the Linux partition which would
make if the fourth primary along with the extended which makes five which
isn't supposed to be possible?

Thanks,
Darrell Gorter[MSFT]

Yes, good point. Seing there's something 'funny' with all of this anyway,
that is definitely a possible answer. Most Linux installers use some variety
of GPartEd, but their own private partitioning scheme with the swap
Partition often being the first primary partition on a drive (good idea
too, I think) so, you can easily run out of partitions on a dual-boot
system.

I have come to the conclusion that Linux on a dual-boot machine, requires
two HD's! (It doesn't, of course, but it may remove some head-ache.

Yes, Carlos, here in Denmark we have a very good Mag ("Alt om Data.") with a
Linux column in it, and I've actually seen these things mentioned there for
many years. I've also seen dire warnings about installing those onto a
Windows system and didn't have the guts at the time to try them out. With
more experience 'under the hood', now - I think I might take a chance and
give it a run one day - I have come to develop high regard for the work of
the OSS community, now - which doesn't in the slightest deminish my regard
for the good stuff that is still CSS.

Good stuff can never be bad, even if it happens to carry a MS logo !

Thanks, for the reminder!
