hi all i have 12 XDA 2 under the Qtek brand. And i have had stupid amounts of issues with sd cards. i have gone though over 30 of em.
im using the latest firmwares and im usign them for tomtom 3.09 and email attachments.
but i keep getting the SD cards dying. do most users find this normal?
i had a sandisk 256MB with my xda1 and that never gave any problems but were a bit slow
with my xda2 i had a 128MB sandisk card also slow
now i have a kingston 512 elite pro and it's fast and ok
never had a sd card die in any device
but sd cards have limited writes before they die but they have 1000's of writes before that
i have had many SD cards varing from dane elec. Viking. and kingston.
all of these are 512k and not (hi speed) just standard. but i hav e had to send so many back for completly dying. my supplier thinks i eat them or something
odd maybe there is something wrong with your xda so it gives them too much power or something
you mean 512MB right ?
Try Kingston. Mines a 256mb and I haven't had any problems at all. TomTom is fast (both version 3 & 5) and never had any die on me
I've also had a 256MB Kingston, which has been faithful in my XDA 2i.
I thought ok, time to get bigger, so put in a 1GB Toshiba, followed by a 512MB Toshiba.
Both of which are now DEAD!
90 quid, Mwaa... Bye bye!
I tend to agree with RudeGar - I would imagine that the HTC manufacturers didn't want the extra cost of a variable regulator to power the SD card, so if it negotiates a lower voltage, they are not able to supply it...
Linux just reports "block read error" when trying to access a dead card, Windoze hangs!
Anyone found a way around this problem?
Cheers,
Richard.
My 256 meg sd card today passed away, it was a viking I think and it contained my tomtom program and maps. I am glad it didnt happen while travelling as I get lost easily, anyway it has now gone to silicone heaven and I am heartbroken.
Anybody got a any cheap replacements :?:
My Kingston 256 MB is OK too, but now I'm very leery of upgrading to higher capacity... :?
yess it is
oh yes it is
dunno if this will help anyone, but i started with a regular sandisk 128mb, then upgraded to a sandisk ultra II 256, then a kingmax (not kingston!) platinum 512mb, then now a toshiba 1gb. All this on my xda2.
all have been fine except one time where i had a problem with the kingmax platinum, but i suspect that was because i dumped it in a card reader, and did some major transferring in and out of large files (movies, etc). Soon it would show a greatly reduced capacity in both my xda and card reader. Got cnetx's flash format, fixed & formatted it, and now it's fine, though i've since moved it to my digicam, and now use the toshiba 1gb.
I had a Toshiba 512 SD which completely died within a week now I have a Kingston 512 MMC+ had it a month and still going strong and very fast.
sd cards...
Hi all, I've got a maxell 128mb and a Panasonic pro high speed 512mb. My Maxell gave me a bit of a scare when i had my Xda2. All my data was wiped off !!! I inserted the card the one day and it was as empty as the day it was born. Took it back to Dixons and that was not much help. They said i can send it away to try and retrieve my lost data.
I cut my losses and formatted the card on my PC. No probs since
I am now using both cards in my xda2i and i've had no data loss.(touch wood)
I have been using 128 and 256 Ridata cards for 3 years without any problems. Also I have used a 512 Astone for the past 9 months for movies also without incident.
I always keep my spare ones inside a case and don't expose them to direct sunlight. They may be tough critters but you can damage them if they are mistreated.
MMC or SD
I have an XDA IIi (Well the Qtek version of it) and am going to get a memory card in the order of 512Mb for it. There seems theres been a lot of bother been had with the SD cards. Has anyone had any problem eith MMC's? Are there any disadvantages to using MMC cards (speed etc)? Can anyone reccomend a cheap SD card at this size that they have had no problem with? Cheers

Hey all
I just bought an SD card from eBay and I'm suspicious that it's an original Sandisk card... My first concern was about the box being decidedly homemade looking (and the card itself wasn't in any vacuum sealed container either) - but now I find I'm having trouble with it as well.
I couldn't find out what size SD cards are supported by my XDA2i so I just went ahead and bought a 1GB one. However, if I transfer around 512MB onto it - it then informs me that the card is 'full'? But when it's formatted and clean, it shows free space as 998MB... What is going on???
Any help is very much appreciated thank you.
Paul
1024mb unformatted, around 998mb formatted is about right.
I have a branded SanDisk 1gb card, and it's fine, there's no difference in file transfer speeds or use than with my high speed PNY 1gb card.
Although thinking about this more, I have read a few reports of counterfeit flash ram chips that report one size, when they are in fact much smaller.
It's apparently been reported on ebay many times where people have bought 2gb usb flash drives, and they are in fact 128mb, even though Windows reports 2gb.
Maybe you should see if you can get a refund?
Is there any way to check to see if the card has been tampered with in any way? It doesn't matter what I do with it, it continually reports being a 1GB card until I put up to 512MB on it and then it claims free space only up to 512MB?
Paul
Incorretct SD sizes??
What file system have you formetted the SD card as?
What size files are you putting on there?
Remember that there is always a lot of wasted space when using small files...
i've tried two 1 Gig SD cards in my XDA 2i now and both of them have the same thing go wrong with them
Seems the 2i doesnt support 1 gig cards properly and sometimes (especially when transfering large files) stop functioning and/or slow down to crawlspeeds.
Alot of the time mine has reported being full even though it isnt. Eject it then insert it again to fix it but the transfer will be rejected.
The only reliable way round it is to transfer smaller files, try Zip'ing the files into smaller chunks ?
I have a pcmcia 1 gig card, its an ata flash type, it used to give me the gig storage until i formatted it on an ipaq, now i can only get 512meg, nothing i do can fix it.
I've formatted it as FAT and I've transfered 56Meg of ScummVM stuff onto it, the rest are large 3ivx files (which are between 50 and 150Meg each). Thing is that I also have a Dazzle card reader which gives the same results? Mind you that's quite old now I guess...

Hello, I've seen on Ebay a minisd of 4gb.
Is it compatible with Treo 750v? Anyone has tried it?
Hey,
Ive tried one in the XDA mini S it works in mine, but doenst work in my dads? think its something to do witht he contact length on the actual mini sd card, the longer the better. BUY A WELL KNOWN BRAND!
Actually I believe it has to do with the either the operating system's or hardware's ability to address 32bit file allocation tables. 16bit FATs only address (under normal circumstances) 2GB volumes. I believe official SD specifications require any hardware requiring more than 2GB to be SDHC (SD High Capacity) wich addresses volumes differently than none SDHC hardware/cards.
So in short, without having first hand experience to try it, I do not believe 4GB cards will work on the Treo. I'm sure, however, that someone will quickly come along and correct me if I'm wrong ;-)
I found this thread http://forum.xda-developers.com/showthread.php?t=289848&highlight=sdhc and then found one on eBay from the link on that page. I won my bid and just paid for it. I should receive it within two weeks, at which time I will try to get back on here and let everyone know if it works for me.
My phone is actually a (UT Starcom) Audiovox PPC 6700 from Sprint, but I would guess that there isn't much difference pertaining to the miniSD driver and what it can/can't read. Also, I can't see WM5 having trouble with the FAT32 file system, but I could be wrong. You *can* format FAT16 up to 4GB, but it is HIGHLY inefficient compared to FAT32 at the same size.
I just hope MS releases a driver for SDHC support soon. After all, miniSD still uses the SD driver. The only difference is physical dimensions, hence why you can put a miniSD card into the SD adapter and it works in SD card readers. The pin-out is the same, etc.
Here's hoping all works well for me. I want to be able to ditch my iPod and only carry my phone.
I have not formatted a memory card with FAT 32. I do not know how WM5 will handle FAT 32 but I know that SDHC has more to do with addressing memory than simply FAT structure. There are hardware differences between SDHC and non-SDHC.
The physical similarities between the SD cards will not make up for the fact that they are internally different. Just like a CD will play in a DVD player but not vice versa. An SD card will work in an SDHC slot but not vice versa.
4GB SD cards do exist but do not fall within legitimate*SD card standards. They may or may not work based on the card manufacturer, the host device, and the direction of the wind. Keep your fingers crossed and your receipts handy.
main question open again
So coming back to the main question,
has anyone tried the 4GB miniSD card (they are all HC, FAT32 formatted) on Treo 750?
I am waiting to decide whether to buy a 2GB or go for the 4GB and come to the same capacity level as the iPhone (4GB version!).
thanks

4GB miniSD cards and the Treo 750
I've got a 750v -- had it for several months. I was using a Transcend 2GB 80x miniSD card that worked just great. No issues with "disappearing", pretty fast read/write, etc.
I wanted a 4GB card so decided I would try a SDHC card from Transcend. It does not work in the Treo 750v. Works fine in my newest PC card reader, but no-go on the Treo. Figured as much, but wanted to try.
Then I bought another 4GB card (non-HC) from eBay that was branded Topram. It suffered the issue of not being able to see the card on the Treo without doing a soft-reset first, and it was very slow in writing to it -- like 1-2MB/sec from a USB 2.0 card reader. Didn't much care for that.
Just recently bought yet another 4GB card (again non-HC) from eBay. It was a generic card. I'm getting 3MB/sec write speed from my PC card reader, which is slower than my original 2GB Transcend 80x card, but not as bad as the Topram card. On the Treo itself, it's read speed is about the same as with the 80x Transcend 2GB card, which was pretty good. Overall the Treo feels about the same with the 4GB card versus the 2GB card installed, in terms of launching Tomtom or playing MP3s.
It also does not suffer any "disappearing" or the need to soft-reset the Treo to recognize the card. I've ejected it many times and put it back it, and have never had any issues with this. I'm going to stick with this card for now, as it seems fast enough and isn't causing me any grief.
This card is shown here: http://cgi.ebay.com/4GB-MINI-SD-SEC...QtcZphotoQQcmdZViewItem?hash=item110080023472
So, that's my (long winded) story on 4GB miniSD cards and the Treo 750v.

I just bought a 4GB mini SD from MobyMemory.com for my O2 XDA mini S. The first card would not register at all with the device. I sent it back and the replacement now at least registers (as 4GB) but after loading any sort of volume of data on the card/device it locks the PPC up!
What BRAND of 4GB mini SD card did you get working with your "XDA mini S" (and did you have any problems once you'd actually started using it to store anything over a few MB)?
Tresend 4gb mini-SD card doesn't work with Treo 750...
stay away from ebay when buying memory(card, flash drive, etc...)
90% of them are fake. Although they might work just fine, chances are it'll crap out on u eventually.
WISH I WOULD OF FOUND THIS SITE EARLIER.
Yeah I just bought a transcend 4 GIG mini-sd for my TREO 750. IT makes the noise as the TREO recognizes it but it doesn't show up in file manager. I have formatted it with my USB SDHC card reader, I can only select FAT32, and it shows 3.75 GIG.
NO GO ON TREO 750 (CINGULAR)
-anyone have any ideas on how to get it to work?

i've recently got my hands on a VOX/s710 phone
my last phone before this used micro SD cards, it was a nokia
when i try to put my nokia micro SD into my VOX, it doesnt recognize, but, as soon as i put it on a nokia, other phones like a palm, etc, it recognizes
is there a problem between nokia branded micro SD cards with HTC?
i tried another brand of micro SD and it worked perfectly
any ideas?
cheers
Initially I tried a NOKIA micro SD card with my Vox and it worked fine.
hum, tks for the reply
so no clues at what the problem might be?
guess if i dont resolve this, ill have to buy another micro SD card
May be, you give a try by formatting the card using a card reader from a Windows PC. That might help.
Yes, make a backup and format to FAT32 (also useful if you want to flash from sd card)! Then put your files back on the card and try again!
thanks for the tips
fortunately, i dont have any indispensable information on the microSD card, i didnt use it a lot, since it was a 1G card, and i had a 2G on my older nokia.
i'm going to try and format it and then post the result hopefully it will work
but since i dont have a memory card reader right now, im gonna try and put it on my old nokia, connect it to the pc and try to format it from there, or format it from inside the nokia phone.
ill figure out something
thanks again for the tips
cheers
=========
tks for the tip tryed it right now, and now its working fine
many thanks both of you for the help!
I have 2 GB microsd card installed. Is it possible to install a 4Gb card or more? Who tried? Does it support SDHC?
Funny thing, I've got an answer from htc support, they say 2Gb is the only possible amount supported

I dont know exactly how to do it search the forum, but i know that there is a thread that says that partion 4gb (using WM5torage that thread tells how to) and then you can use it.
the vox supports SDHC microSD up to 8Gb, found this in www.pocketpc.ch (will post the link l8 when back on my pc).
i'm using a sandisk SDHC 4Gb fat32 formatted, works perfect! i will buy a 8Gb soon and post the results here .
edit: http://www.pocketpc.ch/htc-s710/39075-8-gb-micro-sd-htc-s710-moeglich.html the forum is in german there....
remembered to post this note, after fomarting the sd card, it worked well
just another question though, you guys are talking about 4 and 8 gigs sd cards
doesnt having a much bigger sd card slow down the phone? i've heard of such rumours but never got the chance to tested myself, and since i'm willing to make a sd upgrade i would like to know if its better to stick with a 1 gig or 2 gigs sd card, or i can go ahead and get a 4 or 8 gigs?
cheers
so, finally i bought this fine 8Gb microSDHC from sandisk, and i works just perfect.

i never tried with a 1 or 2Gb card, so there i cannot say. but on the otherhand i did not remark an diffrence of speed with the 4 or 8Gb card, they're just as fast as usual (in cellular device or in pc with cardreader). the only thing i can say, is that cards from cheap(er) brands are always slower than cards from quality brands (such as sandisk, as example). and also SDHC cards should always be faster than 1 or 2Gb cards, because they have a newer controllers (not 100% sure about this point, i think i might have read that in c't).
i hope i could help a little bit...
Dang, 8GB cards work without driver patching? That is champion. I'll be ordering myself one soon.
Yep, can confirm 8gb card works fine, have had one in mine for some months now...
Now what about 16gb? was that article written before 16's were available even the sandisk site seems to be out of date saying nokias that are supposed to support 16's only support 8?
anyone actually confirmed 16's don't work?

i guess we have to wait some time to test it
at work, some weeks ago, i discussed this with a dev. and he meant that from the hardware side it should be no problem, but maybe the driver needs to be updated. i'm not sure, but as i know the driver adds support for sdhc, no matter of the size of the card. he's not a sys dev, he does apps and branding, i'm only test-ex and advanved user, so correct me if i'm wrong (i'm still learning ).
edit: found following on http://www.wisegeek.com/what-are-sdhc-cards.htm
The new 2.00 specification should last a bit longer, as it allows SDHC cards to reach a maximum capacity of 32GB.
Click to expand...
Click to collapse
so i think, if the device supports that specification (and the vox does), it should support cards up to 32Gb.
and again some info about speed:
The SDHC specification 2.00 calls for cards to be classified according to the minimal sustained DTS as follows:
Class 2: minimum sustained DTS of 2MB/sec
Class 4: minimum sustained DTS of 4MB/sec
Class 6: minimum sustained DTS of 6MB/sec
SDHC cards are classified to guarantee a specific sustained DTS. This potentially saves consumers money, as flash cards are priced not only according to capacity, but also to speed. For example, if a product's maximum DTS is 2MB/sec, dishing out extra cash for Class 4 or Class 6 SDHC cards would be a waste of money. Conversely, devices that can utilize the 4MB/sec or 6MB/sec DTR (i guess the author meant DTS, kel187) will perform significantly better with Class 4 or Class 6 SDHC cards, respectively.

my 4Gb card is Class 2 and my 8Gb is Class 4. i did not recognized any diffrences in speed advantages, neither on the mobile nor on the pc. so the vox and my cardreader must be class 2 devices, what a pitty ^^
In searching the forums I know this has come up for other devices and am wondering about the Fuze. What Micro SD speed class can the Fuze use. Don't want to spend extra on a class 4 if it can only take advantage of the class 2 speeds.
Thanks, my Fuze gets delivered late this week, cant wait

While the fuze (and any phone really) can only take advantage of class 2 speed, your computer can use everything higher. Also, I believe when you're using the direct storage card access mode while plugged into the computer, you can take advantage of the higher speeds as well.

I Noticed a speed tweak in the Blackstone forum for making the SD read time 3X as fast. Is there any way to "port" this setting to the Fuze? I'm beginning to load up on movies and want the best format possible for TV-Out.

I wouldn't let thos Class numbers fool you.. I bought an early 8GB Adata Class4 card and just recently a new 8GB Class6 for a neighbor. Just out of curiosity I plugged each into a mini USB reader and ran hdtach on my PC. My old Class4 card read at 19MB/s and the newer Class6 at only 14MB/s. Explain that...
I have two 8 gb cards, one is class 4 and one is class 6. The difference when connected to a computer is around 10%, but on my Pro I didn't notice any.
However class 4 is almost 2x faster than class 2, and I believe that will have an impact on phone performance.
I could benchmark mine if someone recommends a tool.
I'm running a Sandisk 16 GB Class 2 in my AT&T Fuze,and it runs great!

Depends on the brands and models you got as to what your read speed will be, but the class rating actually has nothing to do with read speed, only write. Also, the class numbers are a guaranteed minimum write speed, so a card labeled class 2 could write faster than class 6 in theory. Here are some read-write benchmarks to show you just how they can vary:
http://www.extremetech.com/article2/0,2845,2094715,00.asp
I haven't found any info on the max theoretical read/write speeds of the flash controller in the Fuze/TouchPro to know what they're supposed to be capable of.
As for the speed tweak from the Blackstone forum...I can't see any difference in playback speed using one Xvid and one Divx video in TCPMP's benchmark. Those are the only two formats I have atm, and they're both technically just MP4 video with MP3 audio.
pocket mechanics can benchmark the sd card in the pda
as benchmarking can't be don on the pc as the speeds will be way different
I think I actually have a copy of pocket mechanic. I was thinking about using SPB Benchmark, but I'll give PM a shot first.
http://pocketnow.com/index.php?a=portal_detail&t=news&id=6415
Article on the cab file and post in the blackstone forum. This article has benchmarks in a graph showing the increase. Anyone benechmarked this tweak on a touchpro yet to see if it works like the HD does?
I have to say that I'm pretty surprised by these results. Both tests were done under identical circumstances and both probably suffer a little due to the fact that I had SOTI Pocket Controller running while I ran the tests. I used the latest version of Pocket Mechanic and an Adata class 4 8gb microsdhc. On the left is the "before."

Yes. Unfortunately, throwing all that extra data at a video processing system that was already choking to death hasn't helped video playback, which is one of the main reasons the patch was developed for the HD. I think I may try to flash the HD derived rom to my Fuze and then retest to see what happens.
If we had the right software to take advantage the hardware we could play DVD,s off this thing
I tryed a full 700meg divx dvd rip that stuttered on play a bit before the cab install, and it plays pretty decent now. It had to be the read time of the phone and not the card that was doing it. Now if coreplayer ever fixs the QVT (blue flicker) on there player it would be a neat toy to plug in with the tv out cable.
