I'm using 2003 version now. when battery ran out, programs in my sx66 got lost.
it is said in 05 , programs don't lose even when battery is out.
is it true?
yes it is true, and is the main reason why i use wm5.
Basically in wm2003 your programs and data etc are stored on a 'ram drive' meaning that a partition is created in the ram memory on your device (which clears when the device loses power) - this is known as volatile memory.
You may also have noticed that you have a folder called 'storage' that keeps the data stored in it even when the power goes out. This is because the 'storage' folder is stored on a seperate flash chip, a type of NON-volatile memory, similar to the kind used in usb flash drive and SD cards etc.
Basically windows mobile 2005 does things differently to 2003, instead of using the Ram as both program and storage memory, and the 'storage' chip as a serperate thing it uses the whole 128mb of ram for program memory and the internal 'storage' flash chip for storage memory.
There are various (dis)advantages to this:
1) Your device will perform faster in some memory hungry situations as there is more ram avaliable to the programs
2) The storage memory (inc instaled programs and settings) will not be lost on a hard reset (or power failure)
3) you are stuck with the amount of storage space on the flash disk (no more resizing the storage memory for a few minutes to take a large file)
4) the storage memory will be slightly slower than it was in wm2003, although it is still faster than an sd card and this is negligble.
Basically if your not worried about large files and slightly slower file copy times and you want your data to be there after a hard reset or power loss then this is the way forwards, however you must also take into consideration the many other problems and advantages of WM5 first and weigh out if it will be worth it for you personally.
Hope this helps

in memory there used to be a toggle to adjust storage and program memory, my storage is almost 4MB i cannot install anything, although program memory is 53 MB
kindly any help will be appreciated
You cannot do that any more. It's a relic of when the storage space and the RAM were shared. The biggest problem was that if the phone lost power, you'd lose everything.
There is a RAM disk in many ROMs that essentially performs the same function. In WM5, the area once known as "Storage" in WM2003 is now the main file system. The rest is RAM, and 128 meg is a lot for this phone, so with a RAM disk some of it can be used to install programs. Like WM2003 however, this area is lost should you lose power completely.
Can anyone confirm that I am correct in assuming that the 256k user rom is available to load extra programs and games into without slowing the performance of the device or is it better to load these extra programs onto the SD card.
Thanks
i keeping all stuff except system apps and plugins on memory card, but i think it does not have effect if you load it to device memory.
more needed is system memory and need to keep is as big as possible
Hi,
Device comes with 256Mb rom, but by default, only 130Mb+ is left for user, since the rest are utilized for the core files & OS. If you use the cooked images, u may get around 150+Mb..
Personally, I installed commonly used programs(PocketBreeze/Pocket Informant/etc) into the rom and seldom used/memory consuming programs(Navigator Programs/Games) onto my SD.. In case I need to extract out my SD, my core programs still run..
Just my 3 cents worth.
I don't think anyone has run speed tests yet, but in theory, both the storage ROM and MicroSD slot use Flash, so whichever one uses faster flash will be the best place to put programs. Since most MicroSD cards at this point are pretty slow (especially the larger ones, class 4 and 6), I would guess the Storage ROM MIGHT be slightly faster. If you can find/write a benchmarking program, you could find out for sure.
As long as you don't plan on taking the card out very often, its fine to install applications there, they run just fine.
I personally wouldnt put anything which the device uses constantly (such as today plug ins etc) on the storage card.
I would put things like sat nav on there.

But newer microSD 4Gb, 6Gb and 8Gb Class 2 & Class 4 are quicker than 2Gb and 1Gb. I have a 2Gb fast microSD for my Hermes, and my new Sandisk 6Gb is more than 4x faster than the older 2Gb.
But you're right, the internal memory is much quick that any microSD and sould be used to install programs more used.
Cheers.
I am currently loading ALL my apps on the main memory now, and only games on the sd card. With the 8525 and the stock at&t rom, I only had 30-35mb to start with. With the Tilt, I start with 115mb with the at&t rom (minus bloatware). I am using programs now I couldn't before, like Voice Command. I still have 75mb left over. That's more than twice what I had on the 8525 to start with. For me I don't see any reason to load to the SD card anymore, except maybe games
Side note: I've noticed some programs would corrupt the data on the SD card when loaded there. Like MS Pocket Streets was one. Spb Backup was another. But yours may vary.
Thanks for the replies, looks like the internal memory is the best option for most programs.
I got this message on my Qtek2020i. The strange thing is when I look in Start\Settings\System\Memory it says below “Storage”: Allocated 100 MB, but in File Explorer the size is only 21.6 MB for Storage. Now I have a couple of questions:
1. How can I see which programs consume the memory? (or how can I see if there is a memory leak)
2. What would be the easiest way to transfer the programs installed in internal memory to a SD card?
Trying to solve my problem I found out that the first thing to check should be your Internet Explorer. I opened the PIE-Tools-Options-Memory and I cleared out the history, temporary files and cookies. Now, the memory is back to where it was one week ago.
I’m quite happy. Still I’m planning to use a backup software and do a hard reset. I have not done one in years. It’s about time.
Is there any software, preferably freeware, that is capable of defreagging the internal storage of the diamond?
On my previous devices i have had the benefit of removing the SD card and defragging it on my PC, but this is not possible on the diamond!
Connect your diamond to your pc and select disk drive connexion type. Then go into my computer and find Removable Disk. You can the defrag it using windows as if you were defragging your hard drive
Defragging a flash drive is bad! It will kill it faster.
your answer is here
please read
http://ask-leo.com/should_i_defragment_my_usb_flash_drive.html
while it is true that defragging will introduce more write operations to the storage, the frequency of defragging required to maintain good drive speed is not so high as to be detrimental to the hardware (once every six weeks or so works well for me)
While it may seem that solid state storage will not gain performance from defragging this is simply not the case. a quick benchmark of your own hardware will prove that there is a boost gained from defragging your storage.
here is an article posted by someone that reflects my own findings and clearly shows an advantage to defragging your solid state storage.
I know it seems illogical that solid state should benefit from a defrag and this myth seems to be further propagated by people who have not tested the benefits themselves, but i have tested and know there is sometimes a massive performance boost (over 40%)

no not really
machanical storage like optical and hd's
suffer from fragmention because their seek
time is limited by the fact that fysical heads have
to move to find data
flash and memory however is not machanical at all
and have seektimes in nano secs
so accessing the address space right next to the one
you are currently reading will not really take longer
then addressing one far from it in the flash
so any speed up you may feel is likely to be placebo
If you are afraid defraggers will too often write your SD card on the same place:
- copy the whole SD card to your PC
- delete de contents of de SD card
- copy back the contents from your PC to the SD card
In this way the content will be likely stored without fragmentation and it will be written only once.

I understand all the technical read/write motions of the head in a HDD and why it takes longer if it has to jump about, and i know solid state has no such impairment so defragging should not make any difference but it does.
The speed up is not something i "feel" but a measured improvemnt shown in benchmarking the storage read/write both before and after a defrag. No placebo effect involved

This is an excellent idea
Hi i am using Noni GSPPlot and i would like to load very hi res maps into memory. But for something like that i need about 250MB of memory and the memory i have free is nowhere near that.
Do you know of a way i can instruct this program to use hte internal storage as the program memory?
That was an option with Windows Mobile 5. A feature that enabled the user to select Ram vs. Rom. Thus, this can no longer be done.
no
pre wm5 everything both app mem and storage were really just normal ram
and all storage was lost if one pulled the battery
with wm5 flash was used for storage
flash is cheap and keep it's data when power goes away
but flash have a limited number of writes it can do before it dies
kinda like cd-rw discs
and flash read and more so writes A LOT! slower then real memory
so if one could use storage for app mem
the flash would die pretty fast
and it would be soo slow it woud be pointles
