Hi,

first of all sorry for the double-post. I don't know where exactly to
get help and it is quite urgent.

I have the following problem:

Windows XP pro SP1 and a 80GB harddisk. I partitioned the disk as follows:

- primary partition 20 GB for windows (fat32)
- primary partition 40 GB for data (fat32)
- rest for Linux

This all worked quite fine until yesterday. Btw: I used fat32 instead of
ntfs because I want to have write-access from linux.

Yesterday then, I installed some updates via windows-update (mostly for
the reason to fix the security issues). From then on the second
partition (D:) which contains the data is not shown any longer.
Partition Magic shows me, that the Partition is hiden for some reason.

When I unhide the partition with PM, there is no error message, but the
next time I boot XP, the partition is hidden again and so not accessible.

I thought it might be caused by the second partition being primary as
well, so I deleted the old partition and created a new extended
partition with logical volume. Same effect. After boot the partition is
hidden. Also it does not matter if the partition is bigger or smaller
than 32 GB. It remains hidden.

Can anyone help me? How can I get the partition back to being shown in
Windows just as it was before the updates? And why does this problem
occur at all? Data access from linux on this partition is no problem at
any time. And the harddrive is new - less than a month old.

Help would be appreciated.

TIA

Christian
 
i did some digging and this is as close as i could find for you. please reread it carefully though and see if it fits your problem. hope it helps. You can mark files on a partition that uses the NTFS file system as hidden by setting the Hidden attribute (for example, by using the attrib +h myfile.txt command). If you set a file's Hidden attribute on an NTFS partition, read access to the file from NTFS may seem to be lost.
CAUS
This problem occurs because a logic error causes Server for NFS to parse the permissions incorrectly.

thanks for your time ... but I dont think this is the solution to my
problem ... I don't even use ntfs it's all fat32 partitions. I think I
am going to try a new clean install of xp

This all is not a problem of windows but of a new version of the
Boot-Manager LILO, that I used ... it automatically hides fat-partitions
for some reason. Anyways ... I added the following to lilo.conf and it
works again:


# reset rules for partition changing
change-rules
reset


Hope this helps others who are stuck here ...
