How to use SD card as real Secure card?

Hi!
Could someone point me to info how can I use SD card as real Secure storage of data?
What I need to do - to use it under Win Mobile platform?
is Any 3-rd part software available?
thanks for any information.

I guess it depends on how you define secure?
If you mean 'nobody else can access the data if they get a hold of the card' ... there are many articles on the web discussing this issue - here's a decent (but slightly dated) one: http://www.windowsecurity.com/articles/Securing-Pocket-PC.html
There are a LOT of app's which will provide you with varying levels of encryption for your data - Resco Explorer has an option to encrypt, for example.
Use google (or your preferred search engine) to search for "pocket pc" and "security" (or perhaps "encryption") and you'll get plenty of hits.
I must point out though that we are talking about an extremely portable device. A PDA is just so easy to steal! An SD card is even more so. So if you are talking about data which really MUST remain secure ... you may well be better served by not putting it on your unit in the first place.

Hi
Actually we wanna do a simple thing.
we wanna put our application and data on SD card and allow access to this storage only to someone who have right to do it. (it isn't top secret )
SD category 3 of levels of SDMI security requirements will be fine for us.

But as I understand - there is some problem with it. It is a little bit strange - because every normal SD card has to provide this feature (and it is), but just there is no any suuport of it from OS? even there is no some 3-rd part File System Drivers?
It isn't sounds so hard to implement.

Why do I feel like we got gipped again?
I believe SD is a scam over MMC cards just like 1.44MB 3.5" floppy disks was a scam over the 720KB version... :x

I did some research into SDMI last year, as a part of a contract I was on. I've dug into my notes and found this:

It may be of some use to you. Probably not ... frankly I find the whole approach of DRM to be a joke

SwellDisk 300% Enlarge Memory Card WM5 1.8.6

Hello everyone..
I know this has been talked about befor but i want to have all info about this in one place.
Mods: move around as you wish.... Sticky?
I was looking throu pocketgear and found this : http://www.pocketgear.com/software_detail.asp?id=19899
There is no Demo to download so i thought.... take the risk.
i bought the software and 1 week after i got my reg code too unlock.
I have a 2GB SDcard, put it in my pocketpc ( Orange SPV m5000 , HTC Universal )
i used SewlklDisk and now have 5.8GB of free space.
With Card Export ( software to transforme your pocketpc into a usb drive ) i conected to my pc and..... 5.8 GB USB device detected.
hvent filld it up yet, but RescoExplorer and internal storage viewer indicate also 5.8GB of usable Space.
Here is another one...: http://www.pocketgear.com/software_detail.asp?id=22364
There are some Slowdowns, but only when saving to the SDcard, and only minimal.
If anyone else has this sofware ( or not ) tell me about your expiriences and thoughts..

Try fill it up to over the original capacity. Thats when problems appear apparently....

btw. something similar was here with win95 - doulbe space,& u were able 2 use aprox 60-70% of capacity that showed. not worth of money

In fact, there were a bunch of these programs for Windows 95 way back when. Turns out they were all minimally useful at best and, as I recall, a couple of outfits that churned out "memory doublers" were successfully sued because they did absolutely nothing.

After all these answers, I supose that the experience says that it´s not a good idea to use this program to enlarge the memory? Or is there anyone who have a good experience whith this program??

"Enlarge" seems to be not 100% correct word here.
You may "enlarge" the displayed storage capacity, but real capacity would be not as high, so you'd end up deceiving yourself...
The idea of compressing data written on disk comes up quite often, and then larger disks destroy it. Then again the same occurs on the next level.
I personally prefer the "honest" capacity. There may be applications using the "sparsely filled" files, where the compression would be beneficial; but all round, the gain is normally 1.2-1.5:1 on average files, and might not be worth it, considering increasing read/write times... MP3's or MPEGs, even worse, are already compressed and are virtually incompressible as such -- so if you think more songs will fit on that "5.8GB" card, ... think again
So, I'd just buy a double capacity device. But, tastes differ and your mileage, as Americans say... may vary.

Installing this disables the Visibility of Extended Rom i mean if any one has unlocked Extemded rom & installed some applications in the EXT Rom.
Any solution please ,i even wrote to the CEO of the Swell disk org no responce. Cheers, T

hmmm, sounds too good 2 b true.
can those who have this software test by filling up their cards close 2 their max. level & leave only a few MB's? & then try accessing d files & software stored on d card. this way, we'll know if d app really works.

[Question] Memory allocation adjustment

Hi friends,
After almost half a year using this O2 Exec, I found it's really good and met all my needs. However, there is still problem with the insufficient program memory even though I used the "closed" functions by pocket plus and clean the device from time to time by memaid. I also use the clearnotification.
Is it possible to adjust the memory allocation the same as the Magician or Himalaya? I know they are all different. If we can combine the extended rom of my Exec to the program memory, it may help a lot.
Cheers,

Doesnt work like that anymore. Try a search for persistant storage or the like. Now with WM5 you have storage memory (built-in flash) and RAM. This has been brought up many times.

Know how this works. But, one day I playing with my O2 Exec, landed in the Memory applet. I suddenly had an image on the PPC, which had a slider to allocate memory . The image was merged with the background. But, my PPC had freezed.
Wish I had the presence of mind to click a photograph , before I did a soft reset.
Food for thought, maybe there is something in there, not known to us.

I think maybe the freeze was because you crashed your machine showing that slider.
I have seen someone post on here about seeing it, and the fact that MS recycled the memory screen from WM2003SE and hid that part.
You're never going to be able to change Flash into RAM, they are (three) distinct chips and used separately by the OS.
The only way you could do it is to write a virtual memory driver the same way that WinXP and other desktop OSs use paging files on the hard drive to simulate RAM. Slow, lots of overheads, no advantage whatsoever on the Universal.
So the solution to your problem may be the same as mine:
I wrote off to a company that does electronics work and asked them if they can fit another couple of RAM chips to my device. This page says that there is room for two more (another 64MB?) RAM chips on the mainboard if you can BGA solder. Still waiting on a reply.
A 128MB Uni would kick the backside out of all other handhelds. Oh, and USB host, but that is a whole world of work that nobody has tried yet. Damn you HTC!

Of course you realise that the more RAM you have the worse the battery life will be.

I'm also thinking to put more chip into the free space but not sure that we need to do anything with the OS to run on 128MB hardware.
Can we just put more chip on it? I want to try

New reg-hack: MemHack. Pre-Alpha.

I fiddled around with my wm6'd hx4700 (thanks kuzuhara!) and a registry editor and found a way to make it regard SD as ram and xip from it.
This renders my device to achieve usage smooth enough i allow myself to reffer to the device as a mini-umpc^_^
For SD only atm, miniSD may or may not work depending on your devices driver. No MMC for the time being.
I sooooo hope this isn't old news
Here's to me not ****ing any of your devices up, it worked wonders for me.
P.S
IMPORTANT!
Delete the Program Files folder and reset again once you see the SD's been renamed to Program Files2.
On the next boot it'll mount as Program Files and everything will load from it.
Excuse me, my brains are stuck in google translator mode
4.11.2007
It seems i was rather in the wrong and am taking a whole new direction.
One which involves reading more carefully before i charge head into the guts of windows embedded.
Will take me a while until next post, and it might become hx4700 exclusive, but i promise you some cool stuff to come yet.
Anybody wanting to make their SD into Program Files to save space,
just start resco reg editor and change hklm\System\StorageManager\Profiles\SDMemory\Folder: Program Files.
(Originally is SD Card).
You can also try messing with it, making it into diffenent sys folders, just be careful
Mine is currently application cache (Volatile) and [email protected] Files.
(Running sweet with what i got to with the enablement of complete graphics accelaration, except for a minor hang up when returning from sleep).
Sooooooooooo...
ONLY DOWNLOAD AND APPLY THE CURRENT PATCH IF YOU KNOW WHAT YOUR'E DOING AND WANT TO GIVE BEATING ME TO IT A SHOT!
I'm hoping for a next release in a day, but not necessarily of this project but of an off-chute.
BTW, is it just me or is WM real *nix like?^^

anyone tried this ?

Downloaded, but waiting to see what others think.
Want to know what it does to the SD card and device as the readme does say to move the devices contents of its program files folder to the sd card?????

downloaded it too. but i notice its his forst post.

Lol... it's my first post, sorry..
All it does is make the device call the card drive "Program Files" and set a swap file that's used as most device memory (don't worry, it's faster than most none-nand flash). i had to leave a small buffer in device memory though.
The memory file is unallocated, so just don't forget to leave 528MB free at all times.

Re-read the original post
It is and will be updated with periodic updates should they come.

I've been using it for 72 hours now.
It takes the odd reset to free up memory, but nothing worst than what we had before.

well if all thing got wrong.. anyway to revert it back?.. well ofcourse hard reset is one of it. uhmm.. lets put hardreset aside first..

well.. cant wait to test this.. i made a whole backup of my registry so if thing went wrong.. ill just restore the registry backup..

Good point doube_ofour.
Just export the StorageManager registry key before applying the changes, and if worst comes to worst restore your backed up original.

So, anybody else installed and can connect to tell the tale?

I made a cab with the regs and installed it But I'm still experimenting .. Nothing bad happened so far how do i know the device is faster ?!! how did you measured your device's speed ?

So let me get this straight -- it will use the microSD in my TyTN as RAM -- the icky sticky stuff I run out of because internet explorer, pocket player, and spb mobile shell grab it all for themselves?
Is there any way to specify how much of the SD card is used as RAM -- since I don't really need 1 GB of RAM on my device.
I saw your post about 558 MB free but didn't quite understand it. You also said you need the odd softreset to free memory? but why would you need to free up a few MB when you have access to hundreds?
But thanks for sharing with the community -- if this really does work out well for us, that's pretty freaking amazing.

@DuperMan
Does this hack simply make our "Storage Card" transform into "Program Files"?.. Thats it?.. cant see any speed improvement.. besides my memory usage increased by that means my device will perform slow..
My "Program Memory and Storage Memory" Stays the same as 47mb total on both memory..

Exactly Ragart!
Only it's set to use miniSD, i think you'd have to mess with it a little to make it work on miniSD... if response is good i'll make a mini version.
Remember - It's only been tested on wm6 hx4700!

in my case my program memory decreased by something around 10mb ! and I can't see any improvement in speed too ...

miniSD, hmm? Well that's the slightly-larger brother of my 1GB MicroSD. So I guess I'll just watch the thread and see others' reactions before I try anything (though I do have fullbackups)
Thanks for the quick response. So how much RAM does your hx4700 'have' now? and did you set it to 558 extra for a reason? Just curious questions from a person who doesn't understand the intricacies of reg editing

@doube_ofour:
Use it for a while, constant usage should be smoother. Did you free the space up by deleting the old Program Files as well?
Use it to surf for a while, multiple windows style, and you'll notice the difference.
Also, don't be mean to my hack Don't load it to spite, wait for each app to load and keep on starting apps without (majorly) worrying about a system crash.
@hma4:
The age old method of feel
It doesn't boost anything per say, but your device shouldn't be as compaction ridden as it was, so less mem degradation over time=more time between resets under heavy work loads. and i mean heavy. also, multi-tasking is MUCH more usable.

@ragart:
I set it to have a 512Mb paging area on the SD, plus 512kb in main for caching and another 16Mb for caching on SD, so that's a total of 528.5Mb overall mem, 16.5Mb cache and half a gig paging (good for them internet chaches etc..

i check on the registry that u have made in ur reg hack. seems like all the folders etc is the same even for a miniSD card ... so do u think it will work on miniSD too?

[Personal Opinions] - "Overkill" on System Utilities?

So, lately...
I've been a little curious as to whether or NOT other members of the community are anything like myself; in a sense that sometimes you may install an application, primarily a system utility when you ALREADY have one, if not several on your device.
I sometimes find myself almost looking for reasons to remove some of the utilities, but then I have some kind of "innermonologue" experience, thus convincing myself that I should keep them, because they may eventually become useful.
Here's a list of utilities I currently have installed:
SK Tools
Memory Maid
Resco File Explorer
Total Commander
Pocket Mechanic
Pocket Defragment Kit
Now, my question is... would you, YES YOU... consider this to be "overkill" or relatively reasonable, considering each application serves a purpose?

Overkill
I find it similar to having a set of sockets in my tool box with 1/4", 3/8", and 1/2" ratchet handles and 3 different sizes of pliers.

HAHA I was thinking and about to say the exact same thing!
Yes, especially with the nature of WM (good and bad), I'd much rather have more tools and therefore accessiblity options...just like on my desktop pc.
Unless any utilities have 100% overlapping functionality, I'll install whatever ones have or likely will come in handy at some point. For me, I think it's just a combination of always being proud of when I have the right tool handy for any circumstance, and annoyed as hell when I don't.
I think it's a direct corollary to the same instinct that causes me to keep my "manpurse" backpack stocked with everything from bandaids to duct tape to sharpie marker to umbrella to charging cables to spare (backup) wired headphones to.... you get the idea
EDIT: most of the utility apps we use are relatively small as well, and especially on the HD2 there's plenty of room for as many as you want really

Well, I certainly feel "less neurotic."
I suppose only Texas guys have the questions and the answers.
Anyway, yeah... I just didn't know if others out there, even with our 1GB ROM, felt as if they were overdoing it when it came to system utilities on their device.

I dont think its overkill. Im a little ocd when it comes to things like task killing and such. I run clean ram like 4 or 5 times a day even when my phone is running fine. As long as they all serve a purpose.

Yeah, I hear that...
I use Memory Maid and my RAM Defragment utilities pretty often.
Most folks don't realize that Memory Maid includes TONS and TONS of system features, very much like Resco does... and I suppose SK Tools fits in that category as well.
I clear my temporary cache files and all the junk every 4-5 hours. And I run the RAM Defragment process typically once or twice per soft reset.
I suppose as long as I know that I have the BEST possible system utilities on my device, then I'm never worried about keeping my phone neat n' tidy.

Since it seems that some of you are running SK Tools on the HD2, I would like to ask if there is a hack to get it to work on the device?
I installed SK Tools to my new HD2 today. Latest stock T-Mo ROM of HD2, and latest version of SK Tools. SK tools has both QVGA and VGA versions available for download. The HD2 is neither of those, but close to VGA, so I used that one.
It installed fine. However, when I tried to run it, only error messages, I could not get the app to run, finally uninstalled it.
How did you get SK Tools to run on the HD2?

lol i had the same list of apps as the OP but realized the paid version of SKtools was all I really needed.
Sent from Samsung Vibrant using XDA App

I agree with the last poster, that SK Tools is probably the best of these apps.
As i wrote though, I cannot get it to work on the HD2. It installed fine, but does not run.
Any hints on getting it to work? Does it need to be installed into main memory on the HD2, not the storage card?

Of course I could "just try it". That really needs no saying.
However, since I had a problem when I tried running it before, I am asking if others have had such a problem with it, and how they resolved it?
That is what these forums are for!

i'm not sure why you can't get it to run. mines is installed on my sd card. i'm using a class 6 8gb. what version are you trying to run?
i'm using the paid version 4.5.1.4 win mobile version for wvga phones. there's a new version out but i haven't updated to it nor tried it out yet.

My SK Tools is also paid for, and I think version 4.5.1.4. as well, which I think is the newest version, or at least was as of a couple days ago.
I did not see a specific WVGA version on the SK Tools site. I saw a QVGA version, and a VGA version, which I think is also for WVGA. Of course, I downloaded and installed the latter.

who needs 2 or more file explorers? who needs more then one wifi utility? pick the one that does as much as possible and is reliable and finger friendly. i even stopped using RAM cleaner.

Even chuck norris uses 2 fists

I didn't see anyone mention my 2 other heavy hitters:
1. fdcsoft task manager v3.1
2. schaps advanced config v3.3
I use fdcsoft task manager's RegEdit component all the time, not as fast as TotalCommander, but it's way faster than sktools. Besides, a full registry export with RegEdit takes only 4megs, so I do it all the time before any program install, compared to sktools 80megs just for the registry(not counting the 300meg full backup), which is near impossible to search when i need to retrace my steps. The fdcsoft's ".reg" export is just like that from totalcommander, and could be read with any text editor.
A big problem I have is that schaps advanced config, which i find useful sometimes, can conflict and overlap sktools and bsbtweaks, which i rarely use. None of these 3 have a "Before" snapshot, so barely opening and closing one of them can save some of their preconfigured settings, and I won't know what changed until i come across a tweak which i'm sure i changed, but was reset by one of them, and I'll have to set it again. Anyone bothered by this?
btw, i don't have resco.
