Hi,
I have the following problem with my Qtek 9090 and my 1GB SD-Card:
I installed all applications on the storage card, as well as many documents and files.
What happens is that I lost data on the SD-Card on 3-4 occasions. The result is that some applications are obviously not available anymore.
Plus, many data files (PDF, RM, etc.) are corrupt.
I tried to fill the card on my laptop with big ZIP-Files and checked them afterwards (CRC-Check will proove file-errors), but everything went OK.
This leaves me with 3 possibilities:
- the card is defect and looses data randomly - how could I prove that to the supplier?
- I am running faulty programs on my Qtek (i.e. freeware emulators) - while trying dosbox for PocketPC for the first time, my Qtek freezed and I did a reset. After that the SD-Card was empty!!!
- The Qtek 9090 has some weird problem accessing these cards, resulting in data loss.
What do you think? Can anyone give me some good hints?
Thanks,
vma
try write lock the card?
Then some applications would not run anymore, I guess.
Also, I want to use a "My Documents" folder on the card, to make use of all the space.
It would be nice to hear from you guy's if you a) never had similar problems or b) did expirience the occasional data loss/corruption on the card.
Thanks,
vma
I have an XDA1 with a 256Mb SD card and I've randomly lost all my data twice now.
I have write-protected the card to (hopefully) stop it happening again, but if anyone knows why it's happening I'd be very grateful to hear from them.
On Friday my 256Mb card lost everything (together with all progs and applications on the Qtek 9090). It was something to do with Spb Pocket Plus but haven't really got to the cause.
I had a similar problem on my magician until I looked up the data system. By default my SD-Card was formated in Fat 16. After I formated it in Fat 32 the problems were solved. Hope I could help.
I lost all of my data on 512 MB Lexar storage card today. Only mail attachments and "ingnore my docs" are there. It really pisses me off...
I don't have any idea why this happened - it would be nice to know the reason. A couple of days ago I restored usin Sprite, that shouldn't clear storage card, should it?
Any ideas?
I hear 'Persistent Storage' thrown around a lot here with the WM5 ROMs. While I know what it is on devices with WM5 pre-installed, what about on the Himalaya? If I install WM5 on my Himalaya, do I get TRUE Persistent Storage - ie. my data doesn't vaporise when the battery drops to a true 0%?
Also, does WM5 for Himalaya pretend to conk out at 50% battery charge like previous WMs do (as a precaution, of course), or does it let you drain the battery all the way down to 0%? (PLEASE read this MSDN Blog entry before you answer, else you might misunderstand what I'm trying to say here).
Thanks!
short answer is yes
but if you use ramdisk it dont keep it's data at batt death
being that it's ram

Does that mean my Blue Angel with Helmi AKU 3.2 ROM has persistent memory (Ramdisk excluded)?
yes all wm2005 is persistent
as it dont support storage on anything but flash
without the use of the 3th party software ramdisk from buzz
Ahhh I get it! But how about the limit on WM2003SE devices and older that forces them to report dead battery when the battery is really 50% (refer to MSDN article on first post)? Has that limit been removed on the Himalaya's version of WM5 as it has on other WM5 devices?
Also, for clarity, WM5 stores its registry and other vital system info on the flash storage instead of RAM, right?
Thanks again!
OK since no one seems to know, I did my own tests and:
1. WM5 does store its registry and etc on Flash, but I think most of you knew this already.
2. The 50% limit doesn't seem to have been removed by the WM5 ROM - if I let my WM5 Himalaya run to 0% and leave it for an hour before reviving it, its RAM (32MB 'Flash Disk' for me) still comes back fully intact. If the main battery had truly died, then the RAM should have cleared within 30 minutes, as that's how long the backup battery lasts.

On my himalaya when ever I take out the battery for a min or 2 the RAMDisk data vaporise. What happen, is my backup battery dead?? or like Rudegar said it ram and it dont keep it's data.
mixed reports about this
some ppl get hardresets as in on 2003 devices
just from changing sim card
some dont
guess it could come down to backup batt being poor or dead
because as far as i know the the purpos of the backup batt is to keep
the ram powered so it dont loose its data when the main batt is removed
flash "persistent" ram dont require power to keep it's data

Thank Rudegar
anyone try changing the b/u batt? hell they sholder it on, guess I have to bu the ram to sd
Oop! double post
Backup battery
Yes , b/u battery is inside soldered and difficult to replace . Mine holds data about 10 mins . After it ramdisk is clear . So I most needed programs install in President store ( actually 30,5MB ) God idea is keep data on SD card .
You will not loose any data if Himalaya with WM2005 loose power except ramdisc. I install software only on ramdisc because it's bad habit to install it on main storage, and SD card is much slower. I hovewer mirror ramdisc on SD card, so I can simply copy it if something goes wrong.

Dear Marx2,
Interested to MIRROR RAMDISC ON SD Card. How can I do that.
i suspect he use his filemanager like total commander to manualy copy his ramdisk data to a dir on his sd card
yet, i don't know automated solution
anyway i don't install important programs often
hey,
I was checking my phone for missed calls/new sms when i saw that i had 1MB left on my 1GB miniSD =S the day before i KNOW i had AT LEAST 250MB left.
I thought that maybe my 8125 is just not working properly, so i did a soft reboot, and still, 1MB left, i checked through file explorer, the file sizes all add upto 470MB (this was a rounded figure, not exact) and i even checked the card thru windows, still 1MB left, but the total space is still 1GB, i even scanned it for errors under windows (duno if it works, but hey, better than nothing =S) and no errors..
any ideas on wat might have happened?
So lately my phone has been really laggy and it was really random. A soft reset doesn't do anything and it continues to be slow. It's so laggy that when someone calls, it ends up freezing up on me that I can't answer the phone on time. I noticed that when I use Oxios CloseApps/Hibernate to free up some memory, it successfully does it making my used ram to about 85%, but all of a sudden it moves up to 95% in a matter of 5 seconds.
I forgot which ROM I'm due to it being a long time, but I know that it does have WizFlo on it and that's pretty much all I know about it haha.
This is generally a problem caused by low space on the internal storage. I find deleting sms's and installing software to SD rather than internal storage helps alot with this. I have noticed that the sweet spot for the wizard is to have at least 20mb free space on internal storage. Backup what you need using Pim Backup and then do a hard reset. Install your fav softwares to storage and off you go. Hope this helps
yep that's a pefect answer ...

Thanks so much, this has definitely helped. And I just realized that it was your ROM that I was using haha
Does anybody encountered this?
2 week ago, I bought tmobile hd2 us. The phone storage was 650 mb when I first run the phone using stock rom. I install some aplication. storage is still the same. But when I run and played pangya. Phone hunged then I soft reset. The phone has reverted to factory. but I check the phone storage. The storage was 300 mb. Then I run another application. then it hunged again. I again factory reset the phone. then boots. I checked the storage. It had 110 mb.
Then, I installed an energy rom. Phone storage was 710 mb. I used the phone to browse the net for 3 hours. Again my phone hunged. When I checked the storage, went dowm to 300 mb.
Is this the result of the storage not formated correctly that is why the phone behaves that way?
Anyway. Thanks to the maker of energy rom I used. very fast indeed.
I might as well experiment my phone further.
Does anyone encountered this to their hd?
To those who have used hd2 before. What is the nominal phone storage for both stock and custom rom used?
