Hidden vs True Hidden

Does anyone know how programs like Boot-US make partitions "true hidden"?

As opposed to just regular hidden, which win2k and above seem to treat 
as not hidden. :-(

Hi,

XOSL uses Partition ID 0x17 for Hidden NTFS partition types and Windows XP 
SP2 does not attempt to mount these or allocate drive letters to them.

The 0x17 partition ID is used as this is a hang over from MS-DOS where any 
partition with an ID over 0xF was effectivly ignored by MS-DOS.

Subtractring 0x10 from the Hidden Partition ID gives the correct ID type for 
the partition e.g. 0x7 which is for HPFS or NTFS.

I am not sure if Windows 2000 would be the same, but there is a good 
possibility that it would be.

Kind Regards

Simon

I don't know how Boot-US works, but it would be possible to "hide" a partition
simply by removing the entry from the partition table and marking it as unused.
In fact, that is all that "deleting" a partition does. To restore the "hidden"
partition, you'd have to have the partition info saved somewhere, of course, and
you'd have to have some way of ensuring that the "free space" wasn't reassigned.

When I used GAG to hide NTFS partitions they showed as 17 (using 
PowerQuest Partition Table Editor), but they were visible to win2k.

Now, when using Boot-US to "true hide" partitions they also appear as 
17, but they are invisible to win2k.

Boot-US makes a distinction between "hide" and "true hide", but they 
don't explain how it is achieved.  Enquiring minds want to know. :-)

Plus, I just don't like the idea of having to use proprietary software 
to achieve something that is probably quite simple (but way obscure).

hidden label vs. property and viewstate
In persisting data between postbacks some articles suggest using a label with visible set to false (to preserve the value of the text in viewstate) and some suggest using putting the value directly into viewstate via a public property. My question is which is better? It seems to me that using a property with viewstate saves resources by omitting a label control. Does it matter? Is there a best practice? I would use ViewState myself.. actually, if you set a label to visible=false, i dont even think the control gets rendred at all does it? Regardless, i see no reason to bother with a lab...
