Unreadable dynamic disk (hdd1) after WinXP SP2 installation, still readable in Win2K

[Vizzy]

After installing sp2 *pro* on my first hdd for multi-boot (win2k is
there in another folder) my second hdd (dynamic, ntfs) is now shown in
LDM as unreadable from XP.

However, when I boot in Win2K it works just fine.

I've read all related stuff on MS site and googled, but all advice
targeted
to cases where disk is unreadable due to updated MBR...etc.
In my case, it still has 0x42 for dynamic partition and everything
seems correct.

Very strange..

(hdd0 has two partitions, types: 0x0c, 0x0f)

Maybe someone came across something similar.. please advice!

I've also a second drive formatted as dynamic (which I think was
a mistake. As soon as I get a chance I'm going to convert it to
basic)

I have a dual boot on my primary drive (both XP pro) and I've
installed SP2 on one of them. My dynamic disk is still
readable from both partitions.

Have you tried running chkdsk /f from win2k. Since you can read your
data, perhaps you can backup, recreate and restore. Still, it
would be nice to get to the bottom of it.

Something else to try.
