Multiple CF Cards

Hi All,

If I am designing a system with multiple CF cards, do they both have to be
protected by EWF?

The first CF card (C:) has the operating system and application on it which
will have EWF on it, The second (D:) is just for saving data on and has no
EWF.

My question is will this second card be repeatably written to by the OS or
will it only be written to when data is saved on it.


Thanks in Advance


Jon.
 
Jon,

You can use only one CF if you want. EWF will protect only partitions that you choose. So first partition C: with OS can be
protected. And second partition can contain your application data.
My question is will this second card be repeatably written to by the OS or
will it only be written to when data is saved on it.

No data is written to disk only when there are write requests from applications. So OS should not touch your second partition unless
you explicitly tell him to keep some files there.

Slobodan,

If Jon is using CF cards that show up as Removable, will the OS even
recognize a second partition? I'm not saying that he *is*, but it's
something to take into consideration. Also, would Background Defrag or
AutoLayout touch the second disk, even though it's not a system
partition? I'm still trying to get this straight in my head.


We have a hard disk as our "data" drive, and I'm just curious to know
how "active" that's going to be. We write to it pretty frequently, but
almost never read or delete/overwrite.

No.
But he can switch it to fixed by reprograming CF, or by using filter driver from www.xpefiles.com

Why would you want them in your image in the first place? Just remove such things from your project and you will not have to worry
about them.
Also when you use RAM EWF it is not smart to have defragmenters active since this could consume all your memory for overlay that
would grow, and then your OS will get in, well let me say "uncertain state"

If you have prealocated files and no new files are created, and you just write data in existing files then there will be not too
much activity. Only data writes that your application make on positions in file that you told to be done.
