Hi All
I have seen that the new 2GB MMC 4 card has been released by Pretec?
It is ment to be the fastest flash memory in the world. hear are the speeds:
Read: 22.5MB/s
Write: 18MB/s
Does any one know if this new MMC 4 cards will work in our XDA II's it says it should work in most SD/MMC slots around today... but regarding speed do you know if we would see any speed increases from SD with this new MMC???
http://www.pretec.com
from tests at least with sd cards the xda2 dont handle all that well compare to most other pocketpc's also worse then xda1 which dont use
the poor internal sd interface that xcale have
you can benchmark using pocketmechanics
and try doing a search people have been posting benchmarks they made with the xda series
Thanks for the reply Rudegar...
Does any one else know any info on the new MMC 4 cards???
well i would asume that they should work
but are they not a bit on the expensive side ?
i mean even with the extre speed if it would help
their price are pretty high
compared to some a few 256MB sd cards
and i dont have any serious issues even with my really really really
slow sandisk sd cards
Die MMC 4 Standard defines 4bit in parallel for data-transmission while AFAIK the MMC has only 1 bit data serial for data.
So it is likely, that it will not work.
Alex
but i'm pretty sure that sd also use 4bit in parallel
but i think the problem with the xda2 is that it's internal xcale interface is a mmc interface which is compatible with sd not the other way around
this is also one of the reasons the xda2 have a slower sd interface then xda1 where it have an external chip because the arm200 dont have that mmc internal interface like xcale400
So MMC are not necessary slower than SD?
Hi...
after reading about the new pretec card I went back to read the articles/posts regarding the difference between MMC and SD...
http://asia.cnet.com/reviews/handhelds/0,39001709,39008492-2,00.htm
http://forum.xda-developers.com/viewtopic.php?t=7901&start=0
http://forum.xda-developers.com/viewtopic.php?t=5513&highlight=sd+mmc
So, if I undestand well now, MMC are not necessary (by definition) slower than SD (this Pretec is faster than the Panasonic?) and not necessary smaller than SD... the only difference boils down to the SD feature...
Rudegar (first all thank you for all the help you are giving in this forum... you are of great example! :wink: ) what do you use your SD card for? In particular, do you watch compressed movies on your XDA without any problems in term of speed?
Finally on SD vs MMC...:
-why do u think Pretec made the 2GB card MMC instead of SD?
-why do you think expansys is pricing MMC higher than SD (look at 256 and 1GB)
http://www.expansys.com/d_storage.asp
so it is not even true that MMC are cheaper than SD...
Mentioning Expansys... what are the best places on the web:
-with widest variety (expansys has recently cut a lot... there are no Panasonic etc... anymore...)
-with the past price (I want to buy one finally!!!)
Thanks,
Chris
i use my sd card mainly for music and a few programs that eat too much space and ebooks and a few video's mainly to brag
in terms of speed then i sometimes get nonsync audio on larger video clips
and when i tried journalbar i had sound clickings so i had to turn it off to listen to music (but i'm not 100% sure that was because of sd speed and not just journalbar acting strange)
and then of cause i use my sd for getting files from a pc that dont have a cradle or other sync cable
using the sandisk cruzer if it dont have a sd reader already
I find my battery goes down much faster with the 256Mb SD card plugged in - would a faster 2Gb MMC card require more power, 1. for higher transfer speeds and 2. for keeping powered up?
Thank you Rudegar!
Good point Madkat...
maybe some with a 1GB memory card who has tried the 256 before can answer us... but I think it would be easier if you open a new thread... something like "SD Card bigger = more power consuption?"
hmmm well. i am expecting my new xda 2 on sunday was thinking of gettin a new mmc on it. whts the max. it supports plz confirm. also whts the standard memory on the phone itself.
I have 128MB, 256MB, 512MB and 1GB SD cards. While I do not have any empirical data to prove it, I do not see any difference in battery consumption between any of the cards. BTW - I have 32, 64 and 128MB MM cards as well.
BRosenow: Any chance you could do a little testing, like leaving MMC & SD cards of same capacity in overnight, and a high capacity SD overnight, and checking the new battery % in the morning? Would be greatly appreciated
I'll give it a go and let you know what I have discovered in a couple of days!
How did the testing go?
How did you go with your testing BRosenow??
Cheers!
Thanks for reminding me. My testing was inconclusive, but there does not seem to be any consistent difference in power drain between the different sizes of SD/MMC cards.
I used the same procedures each night - when I got home from work I put my imate in the cradle to be sure it was powered up to 100%. At 10:00PM I inserted the SD/MMC card and soft-reset the device then placed it on the desk beside my laptop. At 6:00AM I turned on the device and read the meter (using the battery meter in SPB Pocket Plus 2.0) and recorded the % of battery power remaining. My first tests were as follows:
1GB SD 89%
512MB SD 92%
256MB SD 91%
128MB SD 86%
64MB MMC 89%
I was interested to see if the same card consumed the same amount of power each time, so I tried my 1GB SD again, and this time 91% was remaining in the morning.
Other things have kept me from continuing the testing, but my conclusion is that battery drain is not linear based on expansion memory size or type and is influenced by unknown factors, but the precision of the Pocket Plus battery meter could certainly be a factor.
Thoughts?
try leaving it in fligth mode
since variations in signal str's can cause more or less
power requirements depending on how much work the
gsm part is doing that night
I can see that your suggestion is a good idea, though I do not think it would make an appreciable difference in the outcome. A total spread of 6% with the given test parameters, particulary given that a distinct trend was not obvious, does not lend itself to indicate a practical difference in power consumption between types of cards or size of cards. (IMHO )
yeah i just talked about one way to make it a tiny bit less unpredictable
5% is always called the stat error margin and 6% is soo close i doubt there is any relation because size and power requirements
maybe the result would differ a bit if the card were being access'd
not sure doubt there is a world of difference because
these types of cards are used in a world of devices where many i'm sure have amp limiters on their sd power curcit to make sure that a camara malfuction would not kill the sd card
so if like a 512MB card required that much more power then a 64MB card
then many cam's mp3players and ..... would be incompatible with those larger cards
Agreed.
I was tempted to write a little script/batch file that would access a file stored on the card at regular intervals, but I just cannot conceive that there will be a measurable difference, so I didn't bother.
At this point I believe that access times are a more important decision variable in which type/size/brand of card to buy than is power consumption.
Hi, did some searching and I believe this topic wasnt covered anywhere else...
The thing is, sometimes when I remove memory card from the phone, some files get lost or corrupted even though no programs were running at the time...so I was wondering is there any way to remove the memory card properly, i.e. there is a menu option on the Nokia N80 'Remove memory card' which closes all running processes so that the mem. card can be removed safely..
the phone in question is a G4 Neo with 2.20.7.114 ExtROM version if thats of any use.
any help is appreciated. cheers
This is very strange. Did you get a chance to test this card in another phone / PPC or at least a card reader?
There is no option like you describe on WM devices but as long as there really is no app actually writing (reading doesn't matter) to the card there should be no problem.
I can tell you from experience that I pulled various (some fairly cheap) cards out from my jamin and other devices even while programs that were installed on them were running (not the best practice) but no files were ever damaged and certainly nothing was lost.
tried it with the reader and with few other xda's, seems to be working fine...hope that was a once off thing...anyway, if theres no option under wm, theres not much choice really.. thanks anyway
yup...I've never faced this issue either, despite my impatience
just found about 30 000 lost files on the memory card with PCs scandisk, (file0245.chk, etc) that were taking up about 3 GB of space
the memory card removal might have been just a coincidence. I think WM Torrent is the one to blame cause sometimes it tends to crash the XDA and files get missing....
I backup the comment from the thread originator. Sometime a spontanious removal of the card causes loosing some of the files in the filesystem. I experienced this several times when making photos. Newly made photos got lost. Seems like problem with syncing two copies of FAT.
Maybe stopping the SD driver with Fdc Soft's TaskMgr should do the trick.
I would recommend to try both FAT format (16 and 32), and launch a complete checkdisk on them after formating to get rid of these issues. If it happens again after this, send your card back to warranty or get another one

I am running WM6.11 - explode I think with the HTC extended rom apps. However I notice that under WM2003 there is a slider to change the allocation of RAM between storage and programs - I dont have this facility on my IIs and run out of storage RAM on the phone despite having plenty of free RAM for programs. It seems that even if I install the application on the card, RAM is still eaten up out of the phone storage - I guess thats the OS system.
However, If it can be done in 2003 then surely WM6.11 can do it - but I need help to re-allocate RAM between storage and programs.
Thanks
it is inpossible in WM5\6\6.1 your information is wrong
storage ram/program ram
I had the same problem, when I converged my EXTrom. I had 93mb in programs and only 64mb in storage. It takes much more storage than program ram, XPLODE, my question is was there a possibility that I/we could have changed this BEFORE we converged?
Also, I and a few others are having a problem with your 6.11 sound disappearing after "X" amount of uses with it (see some replies the past few days)
Don't get me wrong, YOUR 6.11 upgrade is FANTASTIC, I just lost sound and the capability to answer my phone as well as NO SOUND!
GCopher
SX66-BA-ROM ver.:6.11.00 WWE (xplode)
Radio version:-1.15.00
Protocol Ver.: 1337.45
Ext.version:
The same problem here!!
I was also wondering if there is any trick to increase the storage capacity from the programs RAM
FYI: In WM5/6 Storage and RAM have nothing common. Storage is a part of flash memory, that is not used for ROM, and RAM is fully used as normal, regular RAM. Thanks to this when you take the battery out, you never loose data and settings like in case of PPC2003 and older.
That's why there is no storage-RAM slider in WM5/6.
In case of BA, after switching to WM5/6 you have 128MB RAM and that's all. Cannot be less, cannot be more.
Talking about capacity - if you went through correct procedure, you should have repartioned flash memory giving back some space that was reserved for ExtendedROM. All the info you can find in the Wiki.
Thanks for the info - maybe I have not repartitioned my RAM then, I just put it in bootloader mode and flashed it!
I appreciate your impatience with people new to this and this is probably why many senior members just say 'its in the wiki' with the unspoken bit implying find it yourself. However the wiki is not an easy document to find what you want and I know I'm not alone there.
Still, I wil revisit the wiki and see if i can find info on this topic that I have previously missed. Thanks.
partioning the MEM
I followed the wiki to the letter, however, it did not say anything about giving back to the EXTrom. I just went by the procedure and I have 93 mg to storage and 64 to program. no Extrom, and flashed to xplode's 6.11 along with other programs. I do not have to worry with loosing my programs any longer however, the program space is what the problem is. there isn't enough room for most of what I like on my BA. LOTS of space in the Storage. One would think that it should have been one big storage space for both just like a regular PC.
I have had my BA for 2 years and never need to ask any questions I just followed the WIKI. Now I have these questions.
Now that I did load 6.11, now I have no sound after a few days of use. It just disappeared. I can't hear from it and no one can hear me. the phone will dial and it responds to calls but, no sound.
I Would appreciate it of the seniors would not make people like us FEEL stupid, when we ask a make sense question. I have searched the WIKI and through the forums and I get no answer thru these means , therefore, I must ask the question, when I feel it is necessary.
Thank you for your rationality.
gcopher
gcopher, have you ever try to hard reset your BA after that sound problem appeared?
Sound problem after 6.11
Yes I have, I am an A+ certified hardware and network geek and I know enough about programming to be dangerous, I have successfully used this site for the past 2 years up grading my BA with the latest, until now. I decided to upgrade to xplode 6.11, of which I thought wa excellent and still do, I used my BA for several days without a glitch (other than the blue tooth problem with the BA as I think everyone else does, that I have to wear in my shirt pocket when I am talking) The only thing I did was install 6.1 word and excel, when I reset (soft), then the problem occurred, since I have hard reset and even re-installed WM6 to try and shell it. No fix. I am looking in the forum archives for a sound fix, if any. Thank you for asking though.
Here this last few days is the first time I have actually posted something here in the forum, other than posting about having the same problem with the bluetooth problem everyone has, the BA has a VERY small chip for blue tooth. I have several (6) BA for spare parts. I have replaced 2 screens on my own, but I repair cell phones for a hobby. (mostly motorolas) I get the parts fairly cheap. I like to take junk or something that is broken and repair them, I get some self edification from that, kind of weird but I am a musician geek (bass player, and active with a band in the Tulsa, OK area)
Thank you for the suggestion though.
I hope you had a great 4th!
If sound issue doesn't go off after proper HR (the one with NO YES YES), all you can do is to go back to a tested ROM (even wm5) and check if sound will work again. If your RadioROM is up to date (1.13 or 1.15) it might be just coincidence with hardware failure - speaker/mic or just sth on the mainboard.
And about Wiki:
first step of the wizard after choosing upgrade to WM6 from 2003: Expanding the Storage memory
http://wiki.xda-developers.com/index.php?pagename=HTC_Blueangel_WM6_WizzardUpgrade1_WM2003SE0
Anyway, gcopher, your flash seems to be partitioned correctly.
This thread seems to have developed into two directions but thats OK I have something to say about both.
I have read the wiki - used the unhide, unlock and repartition programs successfuly. Then flashed 6.11 xplode successfully. I then go to the memory option in Settings->System and have EXACTLY the same problem as before - the ram is divided into storage and programs and there is no way that I can see to shift some program ram to the storage or vice versa. Perhaps most users dont run many programs on their BA's but I start running out of storage on the phone when there is still loads of program ram - the fact thet I also have a 4gig SD card doesnt help. I find that even when I install as many apps as I can on the SD card I still run out of storage on the phone.
As for the sound. I too lost my sound AND the camers when I upgraded initially - nothing seemed to work and I was convinced it was a hardware fault. I was so fed up I took the batery out and left it for a few days, long enough for the internal backup battery to also run down. Once powered up again it all worked perfectly and has worked ever since.
Frustrating as hell isnt it when you feel like your the only one with a problem and noone else has ever come across it - even more frustrating when your given simplistic advice in minimal detail
I will do a lil explaination, when you delete the partition for extromyou add this space to the phone storage, the only one known way for increasing storage in WM5/6/6.1 is with ramdisk, but it is not working well in WM6/6.1 it is inpossible to make it with slider and allocate memory to ram or storage as in WM2003
arcnet: and to finish storage/RAM problem: Like in the PC you cannot just like that exchange Hard Drive space with RAM, same way you cannot just like that exchange storage (that is something like Hard drive space) with RAM (that is like... RAM
And to explain it all: If you run out of disk space you usually don't try to use some of the RAM as the Hard Disk Space. You can just install another hard drive. In case of PDAs and your BA in specific: consider installing all the big applications on the SD card. This should solve your problem completely.
Tanks Coach!
This is what I am working on now, checking, and going back, being that I have quite a few other BA parts I can go back and replace, however, I will go back and even do the WM2003 if I have to, I have tried many times to hard reset, however, I think I may have caused a problem with that, (I can fix it) but my BA just restores itself. I have placed most of my regular programs on the storage card. It just comes right back up to my background and original settings. I will have to pull the card ans reset it. Either way, I will have to trouble shoot the problem, I have checked out the "soundfix" file no go. The uni-directional file already exists and will not re-install. I will re-install WM5 and see if it comes back on OR start replacing parts.
I had saved the EXTrom on my storage card, as the instructions said.
The program storage has all of the space, and the Storage file has very little, seems it should have been the other way around, this is what the other guy was talking about. If it was possible to go back and re-allocate the two, so storage could have more of the space.
Thank you for your kind response, this is what I love about this site. I feel good about have all of the knowledge and access to programs for this wonderful Device of mine.
Have a pleasant day!

Sorry Arcnet, I do not intent to take this thread both directions...... I should have taken the sound prob to a different thread,
I needed to voice that I wanted to understand your delima,as I had the same wonder. I used my storage card for all that I could and I still have used 92% of my program ram space and still have more than 60% of my storage, as only using 2% of my card. I moved all I could to the card and reclaimed about 10%, however, If I wanted to place more on it, it would still take up more as there is only 64 mg available in Programs and most of the allocation in Storage.
What xplode is trying to say is, the BA comes with 64 mg of ram built in, this is all you can use for programs.
The slider was for EXTrom and storage, that is more like a hard drive on the device. This is separate from the RAM for programs. What we merged was the storage, and got rid of the volatile mem (EXTrom) and gave it ALL to storage. it was never available to programs.
Be sure that every time you install a program...choose your card, if at all possible, the program will tell you (my experience) if it will not run from storage (your card).....................G
Adding to this,I have successfully reloaded the xplode 6.11 with success with restoring the sound. I will let you k now IF it goes out again, in about a week.

Another problem that I noticed (with my BA anyway) is that even if I choose to install applications in the SD card, the storage space reduces as well
I don't know if this related to the BA or the ROM (which is sundream's rom) but this is what's happening with my BA. As a result, I run out of storage space very rapidly..
Any clues??
Just because you select to install to storage card does not mean that all files are copied there. Some files HAVE to be installed in the windows directory. Try installing memaid or tweak2k net and transfer dlls to the storage card, that will free up some memory , depending on what you have installed
Thanks for your answer scousemartin
I have another question though: how much memory can we get if we aplly the resize stuff with 2003??? What I mean is: is it worth the hastle??
If you did not repartition flash to get rid of ExtROM you loose 12 (or 16, I can never remember) MB. It's always worth to have more storage memory, that is otherwise totally lost.
If you have a "sound disappearing" problem, try NOT TO CLOSE (by X button, add to ignored) any players when they are playing. Especially Windows Media Player. That solved the problem for me.
Hi all,
As the title explains, the counter in the camera (and video mode) shows incorrect amount of pics remaining.
I have about 3 gig of space left on the SD card but it only show haveing space for 190 pics. If i change storage location to main memory it shows space for over 400 pics with only 226meg.
weird huh
Same problem
Sorry to dredge up an old thread. But I have this problem too? Does anyone know how to fix it?
same problem for me too.
have 4gb space on storage card and only 190 photos
estimated.
maybe depends on your ROM?
im using NRG 29/7 build
weird thimg is the counter seemed to have fixed itself yesterday, dont think i changed anything!!!
Im using Topaz Essential 1.8.1 - maybe I need to soft reset my phone. I've got 12 gb free and it says I can take 80 photos.
Yesterday it said I could take 30,000 photos (or something like that).
this happen today with me, when i changed from a 4gb to a 8gb, almost 5gb free and only space for 94 pictures.
Strange issue.
PS: Original rom
well seems to affect people with different roms but what about different camera software versions?
start camera, click options, click advanced, page 5, About
report your camera version
mine is 6.16 build 33888
I've got 6.15 (Build 34231)
I also noticed the counter went down to 59 today (even though I didn't put anything new on the storage card).
Maybe it has something to do with the internal storage?

Yesterday i notice that my card was showing more than 4000 pictures to take, today is showing again very few, must be a bug i noticed that this happens very often, sometimes is right others show wrong info, in my case soft reset doesn't solve it, the values exchange from right to wrong when i connect the device in Disk Drive, pretty odd, it's like one time is only considering the whole 8gb card and others TD2 only considers the card as 4gb+4gb.
Same problem here ! 16 GB SD Card but can only take 140 pictures
I formatted my SD Card FAT32 8192 bytes and now i can take over 10000 pictures
( I'm sorry for my very very very bad english )
Hi incidentally the limit doesn't seem to have any effect. I passed the limit and it jumped up to 10000
Well the phone advertised it's Internal Storage as 16GB. My phone has only 8.55GB internal storage and only 0.44GB available. I really don't have much on this phone.
Is there a ROM, tweak, or fix of some sort that will restore more of the original 16GB of storage?
Hard to believe the Base ROM/Firmware take up nearly 8 GB of the original 16 and you can't fix it.
From the digging I've done. None of the Roms restore the 16gb internal storage. I
Umm... I imagine there hasn't been any responses, because it's hard to to respond to this without being slightly incredulous . As you certainly seems to know, your phone does have 16gb of storage and yes, a good amount is taken by the operating system and included software. I can't tell if you understand the difference between memory and storage,though.. I'm not trying to be a **** or judge - you either know the difference, or you can Google it on your own discretion.
There's plenty of ways you can solve this, though... you can disable swap, freeing up storage at the expense of cache. You can 'debloat' your system, though unless you are fairly experienced with using shell commands I'd recommend a pre-debloated rom like madvane's s we ift and slim. Additionally, you can add a 32-64gb sd card and set it as default storage, basically leaving the rest of your free 8-10gb free for just apps. Beyond that, things get a bit more involved.. One solution is to use an app such as apps2sd, which basically requires using a specially formatted partition on your sd card as 'adootable storage', bind it to your internal storage's app resources, making an app located on your sd card act as if itwas right in your internal storage. Otherwise, you canuse similar methods to relocate data files like OBB's to your sd card.
Really, what else can you expect from an octacore 3gb/16gb phone with a 6in screen, that is easily unlocked and rooted, for much less than 100bux..? x]
