Win98 on a existing partition.

[PerezDeQueya80]

(sorry 4 english, I'm italian)
I have configured a virtual machine with a existing partition.
VMware run on a WindowsXP that look the Win98 partition too.
If I start Win98 from vmware and create a file, on WinXP i don't look it.
Than when I restart WinXP, start the scandisk on Win98 partition...
Can VMware write directly on Win98 partition FAT therefore I can look the
change in WinXP immediatly and at the reboot without scandisk?
Thanks

No - you cannot share a partition between guest and host. If you try to
you are almost certain to get file system corruption as both OS will think
they have unrestricted access and will implement their own caching strategy
and will write to it without regard to what the other OS has done.

What you should do is let one OS control the partition, and then let the
other OS access it via a network share. That way only one OS is responsible
for all reads/writes to the partition.

What I must make therefore winxp does not see win98 partition?
thanks

You can't.

All you can do is to make sure that you don't do anything on the host
that reads or writes data in that partition directly while the VM is
running. (only use network shares to access it)

Chuck is write in that strictly speaking you cannot as Windows XP insists on
looking at all partitions. However if you make sure that there is no drive
letter mapped to the drive at the WinXP level then you are unlikely to have
and writes happen, and thus have an accident.

True. That does help a lot.

Since the Win98 partition is going to be FAT or FAT32 (by definition)
there shouldn't be a problem.

If it was an NTFS partition, XP has an annoying habit of setting the
flag on it that indicates a "dirty" filesystem needing
scandisk/repair.

Totally slipped my mind that it doesn't apply in his case because his
Win98 is pretty unlikely to be using NTFS.

You can "hide" the partition by changing the type-ID flag to a
non-standard value eg "1b" instead of "b"

But it might be enough to tell WinXP not to assign a drive letter to the
device. The "TweakUI" tool from Microsoft has a screen that allows you to
select what drives are assigned letters in Windows.

John,

I have found that XP still seems to find partitions where the type is
non-standard. It is as if it looks at the content to see if it recognises
the filing system.

In terms of assigning drive letters, you can do this from within Disk
Management - you do not need TweakUI (although that has a friendlier UI for
doing this)

Changing the partition type is likely to cause a few problems with
actually booting/running that partition under VMware though.

XP still "sees" them even without drive letters.

With FAT and FAT32 partitions it's not so bad, but with any NTFS
version XP will often set the "dirty filesystem" flag, forcing a
check/repair of that partition the next time it is booted from
(natively or in a VM)
