Hi all!
I'm Markino from Italy and I've got some question about I-Mate Jam.
I don't undertand the memory management of this device: how the RAM-ROM and MMC are used by the Windows Mobile 2003 SE? If I install an application, where the files are stored? If the battery drops down what I'll lose?
Many thanks and sorry for my bad English!

Marco, in theory you should let Windows to manage your memory. The i-mate JAM has 64MB of ROM and 64MB of RAM. The ROM is mostly occupied with OS and other 3rd party software that installs automatically when you hard reset the phone. Part of this ROM is also used when using the "Permanent Storage" feature of the OS, where it lets you save some files, contacts, etc.
What should really interest you is the RAM. The OS uses this RAM for running programs (like the RAM on your PC) and the rest is used for storage. If you go to Start -> Settings -> Memory, the OS will tell you how much of your RAM is being used for Running Programs and how much is used for Storage.
The safest place for your data would be an SD Card, as anything stored on the SD card will stay in tact after a hard reset.
Thanks kta! You're great!
Well.. in your opinion what is the best way to use the Jam's RAM with a 512MB SD installed?
I can configure the device to use all the RAM space to run program and store all the file and app. in the SD or it's better to use a part of RAM to some particoular application?
The SD Ultra II are really faster in the Jam?
The more free RAM you have the faster your mobile works. I would suggest installing most of your programs on the storage card. Before installing a program make sure that it can run smoothly on an SD card. Most programs do work well when installed on the storage card so it shouldn never be a problem.
Having said that, RAM is MUCH faster than an SD card, although modern SD cards like the UltraII give over 9MB per second (66x) write speed.
A more complex option (the one I'm using) is to install a hacked ROM (aka Big Storage ROM) where you will be able to gain an extra 27MB of Storage (i.e. in RAM). You can then use this storage space for installing programs and these should work slightly faster than when installed on an SD card. However, installing the hacked ROM requires some experience with ROMS and would not suggest you go for it unless you want to end up with your JAM stuck in bootloader mode :wink:
With regards to SD cards, the faster the speed (i.e. 40x, 66x, 133x) the better.
And if you intend to use your JAM as an MP3 player I would suggest going for a 1GB or 2GB SD card. The price difference usually justifies the extra space! Before buying a 2GB card, check these forums for compatibility issues as some of them did not work on the JAM.
Hope I didn't confuse you more!
SD card speed on the JAM makes no difference for operating the device, since the JAM can only read/write the SD card at the standard speed - buying a faster card makes no difference.
A faster card is useful if you frequently copy large files between your SD card and your PC, but for the JAM it makes no difference.
Microsoft said in WIN2003SE it's always recommended to install mostly used programs into MAIN memory cause it's way way way faster than the extended rom or storage card. So on my old PDA2k I installed regularely used programs like Pocket Informant, Voice Command etc.. on the internal memory for enhanced speed.
I was wondering if anyone knows/ did benchmarks of Read/Write/Access Speed of all 3 memory mediums available to us JJ/Exec users ? That is Internal memory, Extended Rom (Which was unlocked thanks to buzz) as well as an SD Card.
Thanks guys

I have a 60x SD card - at least I am TOLD it is a 60x card - but Pocket Mechanic benchmark tells me it is just 4x. (Perhaps someone else who has PM could give us THEIR SD card benchmark figures for comparison?)
It was suggested on this forum the problem might not be in the card but in the SD port. If so, the Universal's SD port could be a serious hindrance to good performance.
The weird problems happened to my Dopod D810 twice.
The first time: The whole file system on card went crazy with all folder names became gibberish (like: &%*()jhui&%^&&!#%&). After a soft reset many folders disappeared, a few folders remained but became duplicated but many files inside were not readable (e.g there are two identical folders named My ebooks).
I thought it might be card-related and I hard reset, formated the card, and re-installed all softwares.
Today it happened again but differently:
- I had some video files in Storage card\My Documents\My Videos folder like this ... video_28.mp4, video_29.mp4, video_30.mp4
- After a video shot, I opened Resco Explorer to check and to replay but all folders and files previously in Storage card\My Documents disappeared. Other folders and programs on the card were still intact and ran fine
- I tried shooting another few video clips (with option saving to card, of course). They all disappeared after shooting.
- But the weird thing is: After shooting, I chose the preview option and WMP played the file well. I paused the playing, check the properties of the now playing file and it showed clearly: Storage card\My Documents\My videos\Video_33.mp4
But in File Explorer and Resco explorer the Storage card\My Documents is absolutely empty despite the file IS BEING PLAYED in WMP
- I tried again and again, the video clips preview were always named in sequence like video_34.mp4 then video_35.mp4, .... but they all mysteriously disappeared.
What is wrong? Has anyone experienced the same problem? Is that a hardware failure (writing-to-card)? Should I send in for repair? Please help! I have some important clips that I really want to keep. Is there any way, any tool to help recover the files that are probably still there?
Do you have another miniSD to run some tests?
This could give you an idea of what is going wrong?
The miniSD could be malfunctioning.
Regards!
Apparently, you are a new user here...
The Trinity has a hardware problem that HTC can't still fix by now. Go search for some posts. There is currently NO solution available - you may try cards with smaller capacity, or you do some preventive measures, such as install SD Sentry.
I have found that rebooting without the card in and then putting it back in sorts this out. Also I am attaching fixes from HTC and others which stop minimise this happening. Finally, it is suggested you use the Sandisk MiniSD Ultra II cards instead as they have a faster transfer rate. These are available on Amazon for about 15 UK pounds.

Damn it! They're gone
Thanks for all the suggestion.
I did reboot without the card then reinserted it but didn't help.
The card is Kingston 2GB
@Nighthawk2050: what does the first patch do? the second patch seem to be for another set, not Trinity?
@WW2250: what does SD Sentry do?
I bought a Transcend card reader, but could not recover any video files.
The card reader however showed the My Videos folder containing only one last video clip.
It also showed 4 other folders which report error when clicked on

There are also 2 other files
/p300p1..gif (two dots) with a reported size of 1,838,093 KB
i/p320p1..gi with a reported size of 789,709 KB
I think with a faulty product like this, I have the right to return it (to Three Australia - a 3G provider)
I think they only have one other 3G set which is the Dopod 838 Pro
Please advise if the 838 Pro has any similar problem (or other potential problems)?

First patch (miniSD HC Patch.cab) don't work....download the new one from the official thread (anyways, it work only on LVSW's ROM v2.0.1.1 and on AX3L's ROM anyversion) http://forum.xda-developers.com/showthread.php?p=1341004#post1341004
Second patch (ArtemisSDEnhancement.CAB) is only for ARTEMIS, not Trinity
Try Panasonic SD formater for format your SD card.

The first patch might not be working for WM5, since it was originally extracted from Hermes WM6 ROM. But you mileage may vary.
SD Sentry is a program written by a Spb developer, who had exactly the same problems of you (for his Artemis though). At that time, there was no fix available from HTC. So he wrote that little program to check constantly for indications of SD card corruptions, such as missing files or folders, screwed up file and folder names, etc.
If such indications are found, it offers you a warning and an option to reboot such that you won't be doing further damages to your card writing to it in an already corrupted state. If you reboot in time, you can yourself a day before it wreaks havoc.
For details, you may want to visit his page at http://www.nixie.narod.ru/sdsentry/index-en.htm
BTW, there was an official fix from HTC for Artemis, but none is released for your precious Trinity, AFAIK.

Don't know for sure for 838 Pro - but it seems to me that this problem is a special free feature from HTC for newer devices like Artemis and Trinity. Besides this issue, I think it's not worth to go back to 838 Pro since it's an older device, slower, and has different sets of problems by itself.
I read extensive from the Artemis forum - and from there I learn that they have a worthy workaround that you may want to try: Don't ever press the power button - let the power save timeout take care of shutting down the machine when not in use.
Their theory is that there's a problem with the HW/OS that interact with the SD card whenever there's a power event, probably lies in the cache or the controller, creating corrupted filesystem data, when unfortunately being actually flushed to your card, would actually inflict real damage. So, if you get strange card suddenly disappear errors, strange filename folders, etc... you'd better reboot it immediately.
Removing the card and re-inserting it seems to reinitialize the driver and will probably revive your card too, but I'd say reboot it is your best bet.
Looks like you now need some software recovering tools to savage your files from your already damaged card. Grab as many as you can recover, re-format the card, and install SD Sentry.
I thought Dopod 838 Pro (Hermes 100) is more or less the same as a Trinity with a keyboard and without GPS?
Anyway, maybe I have to stick with this Trinity for now.
About SD Sentry: another program, would it further slow down the phone?

It's incredibly light-weight. I even forgot its existence once installed and configured. It never get into your way unless absolutely necessary - when your card get corrupted
Hope it helps.
Hmm maybe its only my trinity but I observed everytime all the SD data is lost is when I use the internet explorer to download and install something onto the ppc.I've done downloading Flash player 7 from my ppc internet explorer and after a soft reset the sd data is also lost.tell me if I am wrong pls.maybe we can avoid it by not using the ppc i.e. to download stuff and intsall it
if you can reproduce it every time exactly, then it's good. Record the exact procedure and tell HTC about it. I read the guys at artemis forum did that and get a fix from HTC.
I want to do that but I just couldn't reproduce it.
Hello,
same pb with me. Pretty anoying...
I saw that i'm sharing this pb with several people. but doing a wide search on google doesn't give the impression that every body has this pb.
Is it a hardware pb, should I take in back for repair.
Does a WM6 upgrade would solve it ?
thanks for your help.
It's indeed annoying especially when you got nothing left in the card. I don't know about the scope of your search in google - but it's a pretty big problem here in this forum - definitely not limited to Trinity or Artemis.
I am sure not everyone encounter this problem - since it's quite related to write i/o activities to the card. Playing music with media player count as one - since it updates (read: writes) the DRM files in the card automatically whenever it is running; people who use camera reported corruption; and the original poster who downloads and installs cabs on the card.
It's definitely a hardware + software problem, which might be able to get fixed by a software driver patch, but only after HTC has identified the root cause of the problem. That's why I asked s4cr3d to report the bug to HTC if he has a recipe to reproduce the bug step by step.
Take it back for repair? Forget it. WM6 doesn't seem to resolve it as well. I read someone with WM6 (cooked) still have this problem. Don't know about the official rom.... yet.
thanks for your answer. need to wait then... still great device...
I'm using AX3L's ROM v2.0.8 and I must say the SD problem affects WM6 cooked ROMs too. It seems to me that it has something to do with software/hardware incompatibilities.
The specs are as follows:
- Corsair 2GB MiniSD
- AX3L v2.0.8
- AX3L ExtROM v2.0.5
The problem started when I used Resco Explorer's built-in unzip tool to unzip a file onto the Storage Card. Everything went ok until I opened up "Storage Card" and went, "where's the My Documents folder?". In a spectacular twist, I managed to corrupt the card (thru formatting, re-formatting again and again) and now it's dead. I used Panasonic SD Formatter, formatting in Linux, etc. and they weren't much help. My word of advice is to store everything safe in your computer the moment you see disappearing files because it might just go downhill from there.
I strongly believe it is Resco Explorer but I cannot verify this cos' I don't wanna screw up more cards.
I have since bought a Sandisk 1GB card and reflashed AX3L v2.0.8 without the ExtROM (and so, no Resco Explorer). It might be the card, it might be Resco Explorer but I have had no problems since (it's been 10 days now).
Anyway, hope this helps someone in some way. Will definitely try the SDSentry program just to be absolutely safe. These cards don't come cheap over here..
Hi,
what is the size of your SD-card that you are using with your WM6 BA?
Does Helmi's ROM support up to 4GB card?
I'm asking because I'd like to buy a new one - preferable 4GB.
Thanks in advance
Phily
BA supports standard SD cards not the SDHC.
So if you manage to get more than 2gb on a regular SD card that would work.
I guess that there is one company that make 4g regular SD cards.
I have 4GB card (Platinum brand) that is not SDHC and works fine in BA. Ideal for multiple navigation systems.
I think Transcend have 4 GB card that is reported to work in ba
(I have not tryed it)

I have 4G Transcend SD 150x (it is not SDHC) - works very good, but it is slow card. (very slow writing data, both WM5 and WM6).
Thanks
Thank you for your feedback!

With the cab SDHC.cab it's possible to read card up to 8Go.

Not in Bleangel
teddybear3k: have you tried? I go for xplode and say, that it's not possible.
Not possible until skilled programmer rewrite the SD Bus driver
SDHC
what about this? (WARNING THIS HP offers warez aswell, but following links are, so far I know, to free ware! So please do not warn, kick or ban me for this links.)
Page Link -- http://myppc.ru/2007/09/14/sdhc_driver.html
File Link -- http://myppc.ru/uploads/files/myppc.ru-1881_sdhc.rar
Is it the same? I would like to install it, but I'm aware, if it could scratch my device....
The given page actually is a good newsticker for PPC programs, I like it even more, than HPC.ru
if this cab should work, then even SDHC Cards with more then 32GB should probably work aswell....
wfg. - Mihail
Mihail: on the list there is NO BlueAngel. Installing it won't kill your device, you will just loose SD card access (and you will need to reverse the operation or make hard reset to get back the access).
We need SD driver made especially for BlueAngel.
List only tells,
on which devices this driver was already applied! Not for which devices it is maid!
That's why!
Mikhail: test it and report. Make backup before and prepare for HR.
Test to 50%
O don't have any SDHC cards! So I could only test, if this cab allows to use SD-Cards, not more... but I will do it!
HTC driver - but not BA
Is not working for BA.... and I'm not a progger (and for shure not a disassembler/hacker) to change this.
So you just confirmed what we said. Please confirm it on your own before publishing any new "breakthru" news.
sd bus driver
Does any one you think that it is possible to use the bsquare development kits to build support for higher/faster sd cards for blue angel?
If you had source code for the SD reader driver and knew how to update it to support SDHC (by hand probably) yes, this is doable with ANY devkit. Without this you are left with desassembling and analysing it in assembler/C.
sd card
hmm i am a high level programmer. (But I like to dive into the subject for giving something back to this community) (I can program in C but have never build a driver before) (Assembly is far beyond my scope) Though I have some good system programmers in my business environment. I will post my findings in this thread and maybe it's a good idea to change the direction of this thread to making this possible (and the way to doing it) instead of asking which is the max card working on the blue angel. Making the BA take advantage of the new generation SD cards is IMHO a very important step.
I bought A Sandisk 1GB Mini SD Card off of ebay for $10
-just the the card no card reader, or adaptor of any sort.
I insert it into my wizard, and it fits it with the spring loaded mechnism fine, but when I go to memory managment, im not sure if it knows it's there or not
Memory management will say that, that "external storage": "Not Installed"?
But when I go to take pictures, I go to the utilities/options menu, then general tab, and it doesnt even acknowledge that theres their a card in the slot, only seeing system memory.
So my question is, are their any programs that can/will format my card, or implement something to make it work?
I have Total Commander(not installed), and thinking about downloading this program called "SKTools". Would these programs work.
Cause not only is this a brand new card, but i have pictures and programs that I want to get installed on this device.
-Ive already amazed myself by using the Lockiwiz, to unlock my phone(having only 2-days worth of exp with a smartphone device)
-taken a few pictures, which i have to downloading off my wizard through activesync
-An some other freeware programs that want to install themselves on the system memory
Please help, all/ and any post greatly appreciated
Thanks!
EDIT: I downloaded SKTools onto my device, and its a cool program( I think its a alternate version of total commander but you pay for it?), but it doesnt recognize my Mini SD card either!!
-I also found this program called "WM5Storage", in the description it say that it's specialty is dealing with "external storage", downloading/ and uploading without the need of activesync?
I used Paragon Partition Manager to partition my minisdhc
panasonic
SDFormatter
the setup maybe you find in www
here is the program-folder,
just extract to c:\programs\
or use a CANON DIGITAL IXUS 65 or else DigiCam
