Hello,

We use that space as well with our DiskPatch software, and others do as well; bootloaders, old PowerQuest tools, Ghost etc., some encryption software may use it. Over the years I have seen so many 'crap' written to those sectors (because we get to see a lot of logfiles from our customers). On a xxx heads / 63 sectors, this gap will be normally 63 sectors indeed.

But you can NOT just assume the sectors are free for use, and you can not assume others will leave 'your' sectors alone. So, only if the sector is empty or contains a repetitive pattern (F6h F6h F6h F6h for example) we assume the sector is free for use.

So before you use the sectors you need to verify if they're free for use, but also after storing your info there you need to implement a mechanism to verify your data is inact once you need it (a simple checksum will do).

Hi guy,

I think I should make clear of my idea:
1. The data I want store here will can't be accessed by user
applications, so they are safe, isn't it?
2. These data can be easy accessed by application such as pre-os boot
loader, because they are OS or file system independent.

So, do you understand what I want ?

I scare of the stability of the "Partition Gap", is these sectors always be
63 or not?

Thanks for you response.

Hi all,
When using WinHex to view my hard disk, I found there are some continues sectors named "Partition Gap", What's Partition Gap?
I found that the EBR(Extended Boot Record) of the following partition is located at the first sector of the Partition Gap, and the next 62 sectors is empty, like this:

| EBR | The sectors is empty, can they be used to store custom data? | VBR | file system ...................
0 1 63 64

I want use the "unused sectors" of the Partition Gap to store my data, can I?

Wish your suggestion !


Thanks for all

Robin
