"Dynamic" H/D on XP is unreadable in WIn2000 ???

[surface9]

I have dual boot system (XP, sp2 and 2000, sp4), each system on its
own harddrive. I keep the wn2k h/d disconnected until I need to boot
from win2k.

Recently I added a new 250g SATA h/d under XP, and, the ONLY way I
could see that XP would let me partition it and format it to NTFS was
to first set it as a "dynamic" h/d. I did this, and it partitioned
the full 250g and then let me format it as NTFS. I have been putting
lots of data on it, and, today, I needed to boot up under win2k, so I
connected my win2k h/d and booted up ok, but, the new drive was not
present under windows explorer. When i went into data administration,
it showed this drive as "unreadable", and offered me the option to
convert it to a "basic" drive, but warned that all data would be lost.

What is going on here? Is the NTFS system under XP somehow different
than under win2k? What is so special about XP calling this drive
"dynamic"? If it makes this drive unreadable to Win2K, then I didn't
want to do it, but, XP didn't offer me other way to partition this new
250g drive unless I first made it "dynamic".

What is the correct procedure for partitioning a brand new h/d (oem,
no software comes with it, just bare drive), and formatting it NTFS so
that it can also be read by win2k as well as XP? Also, XP doesn't
offer me any way to make this drive be "un-dynamic" - I can't take
that attribute away (as far as I could see). Why would anyone want to
hide a new h/d from other boot systems?????]

Puzzled and frustrated!

Dont know details but your win2000 may need sata drivers

First off, you will have to import the dynamic disc...

I'd back up all the data on it and then wipe it out
and convert it to "basic" and never again use a dynamic disc.

When you first installed it you should not have set it up as "dynamic",
with an SATA disc, win2k *does* give you the option to set it up as a basic
disc...
but the way disk management works, I have to say, it is not made terribly
obvious.

What you should have done instead of right clicking on the partition...
you should have right clicked on the identifier box on the left...where the
drive is ID'd

such as "Disk 1"

You then should have had the option to create a basic disc

Did you try the import foreign disk command?

Dynamic disks and volumes

If it makes this drive unreadable to Win2K, then I didn't
want to do it, but, XP didn't offer me other way to partition this new
250g drive unless I first made it "dynamic".

Not a truism.

What is the correct procedure for partitioning a brand new h/d (oem,
no software comes with it, just bare drive), and formatting it NTFS so
that it can also be read by win2k as well as XP?

What normally happens when you boot up Windows XP with a new disk is
the Initialize and Convert Disk Wizard pops up. See

Also, XP doesn't
offer me any way to make this drive be "un-dynamic" - I can't take
that attribute away (as far as I could see).

You can right click in the Disk1 box in Disk Management, and select
the revert to basic command. However, data will be lost.

Why would anyone want to
hide a new h/d from other boot systems?????]
