SD Card which format - JASJAR, XDA Exec, MDA Pro General

Hi there,
my 2GB SD card has just arrived and I am wondering which format is safer/faster with WM5, and which cluster size is recommendable...
Thanks,
Manuel
P.S: I benchmarked the card with Pocket Mechanic (it is an extrememory 133xSpeed) and for reading I get a value of 0.96 M/sec - thats quite slow for a 133x Card, isnt it?

IMHO the larger FAT means seek times are much slower for small file writes. In my personal experience, my old old 128MB Panasonic SD card is much faster for general usage than my 1GB Sandisk Ultra II.
Of course, if you copy movies and music onto the card, the 133x would be faster for sustained transfers...
All that, and I can't really answer your question

1Gb SD card - does XDA II support it?

Does it?
Thanx
Igb Card Support
Yes I am using a San Disk Igig card for GPS Maps with no problem.
great ! thanx......
...and I use one for movies!
1 gb
i use it for my MP3s and movies as well.
what about high-speed x60 1G SD card ?
faster then normal speed ?
i'm using 1gig 60x pqi sd card. oftentimes it works. problems encountered: xda2 can't detect the sd card. never done the 3x format yet.
you won't see much in terms of speed in PPC. all these fast speed SD is meant for digital camera & video actually.
I have a 1Gig card by 'Integral' that claims to be high speed. I was having some problems running gps mapping etc from it, though for mp3's and videos it was fine.
I have now bought a 512 SanDisk Ultra 2 card and Tom Tom is much better with this card. Using a multiple file read/write test to copy from the card to itself, the new Sandisk card is significantly quicker, and Tom Tom runs/opens much better than it did with the 1Gig card. So higher speed cards do show an improvement, though not as much as when they are in a device that can take full advantage of the card, like a PC card reader for instance.
I have a x66 PQI 1Gb SD card that I run TomTom3, MP3's and store presentations on. I have had no problems with this card at all. The higher speed of the card does make difference and improves the performance to both the applications and the speed at which data is copied to the card (not using hotsync).
Ive found that some really cheap SD cards have loads of problems.
I bought a cheap card and it was terrible, kept not working, corrupting files etc. I swapped for a 1gig Sandisk, all is well, no problems at all.
I found that the 32meg NOKIA cards given with most new nokia phones a year or so ago dont work. They are totally unreliable.
You get what you pay for, the faster cards are normally more expensive, and ive noticed the difference when copying big files from ram to card.
Get the better cards, its worth it in the long run.

XDAIIi & Best SD Card

Hi.
I have many questions which have been skimmed across on quite a few other topics in this forum, I wish to ask more in depth questions for all you IT Brainiacs which I lookup to greatly 8)
I own a XDAIIi and a 512MB Kingston SD Card.
Using 'Storage Tools' by softwinter...
http://www.softwinter.com/storagetools.html
The SD Card is formatted:
FAT 16 (Backup FAT)
Cluster Size (The Largest Size)
I also use TomTom Navigator 3.07 with GPS 3.07.
I experience frequent lockups whilst driving.
What I am asking you guys is what is THE BEST AND ULTIMATE SD CARD to use in my XDAIIi with TomTom.
I know about all the Sandisk Ultra II/Extreme III but pocketgps.co.uk...
http://www.pocketgpsworld.com/storage-card-compatibility.php
Do not advise using Sandisk cards due to their poor performance.
Do any of you guys recommened how to tweak my SD card but increasing/decreasing the cluster size or formatting the card with FAT32 !? Or are there any REG Hacks that people know of how to increase the stability of the XDAIIi using the SD Card slot.
Also are there any solid specs of HOW fast the XDAIIi SD Slot can Read/Write to SD Cards?!
Sorry to ask such harsh, to-the-point questions but I have learn so much from this forum and will be donating money soon as if I were to ask or ring the customer services of the products I own they would charge a bomb on phone calls and not answer my questions.
This forum does neither of those
Thanks in advance,

SD Ram XDA IIi
The only card that I have found to reliable with the XDA IIi is the Kingston, I have the 1GB version currently formated FAT16 32 Secs, 512 bytes per sector and Tom Tom functions perfectly...Hope this helps...
Hi there. thankyou for VERY quick reply.
Please could you explain more about the way you have formatted your card.
I understand the FAT16 bit but what do you by 32 SECS and 512 bytes per sector.
Thankyou again,
lydiachris
ps. I take it that you are using the standard Kingston (blue), not the elite pro version (white)
The Kingston "Elite Pro" range is miles faster than the standard kingston SD cards, and only about 20% pricier (at http://www.picstop.com/securedigital.htm). Just replaced my Kingston 256 with an Elite Pro 1GB, and Tomtom flies! (5 times faster to load)
PS if you're using Tomtom's GPS 3.07, you might wish to change to one of the earlier versions that doesn't hijack your BT stack (Pocket GPS world has loads of info and downloads for this)
Hi there. Are you serious?!? Do you have a XDAIIi ???
I am currently using a standard blue kingston 512MB SD.
But I have just bought an Elite Pro 512MB SD Card for £33 which I am quite pleased with
Please could you post some more info on the formatting question I have posted above.
How did you format your card Fredrick_Fredrickson.
Also what does the 'Cluster Size' of an SD Card mean. I understand that if you have many large files i.e. like TomTom maps (all the individual files) then it is better to have a larger cluster size than say if you have many little files like photos.
Am I correct in saying that!?
Cheers,
Lydiachris
Ps. has anyone got one of these?!?!?!
http://www.kingston.com/digitalmedia/sdultimate.asp
Very serious!
5 times quicker to load.
Just did a quick back to back ABA test, starting up Tomtom.
Kindston Elite Pro (1GB): 15 seconds
Kingston Standard (256Mb): 53 seconds
Both cards formatted FAT32 with default cluster sizes.
Test on an XDAII (not XDAIIi)
Note that the new Elite Pro cards are also blue, like the standard ones.
Hi thankyou.
That is really amazing!!!!
Could you please look further into how your cards are formatted, i.e. cluster sizes.
Why FAT32??? Doesn't this cause lockups whilst your using tomtom????!!!!!
I thought that SD Cards usually work better with the FAT16 file system?
Actually, do you experience any lockups at all with tomtom???
Regarding the colour of the cards, what colour is your elite pro card???
Because if you go on the link that I posted above, they are actually the ultimate kingston card.
With 133X read / write etc...
Cheers,
lydiachris
The manufacturer of Storage Tools says (http://www.softwinter.com/storagetools_faq.html):
Q: What file system I should use FAT12, FAT16 or FAT32?
A: It depends on the storage card size. For larger cards, 64MB and up, the answer is almost always FAT32. FAT32 can be incompatible with digital cameras.
My cluster size is:
256MB standard card: 512 bytes
1GB Elite pro: 4Kb
I've not had any trouble with lockups (touch wood)
My card colour is blue, but it is definitely an Elite Pro, not an Ultimate.
Hi,
For those experiencing lockups using TomTom 3 and XDA2i please look at my thread, its not the SD card its the Phone that causes the lockups.
http://forum.xda-developers.com/viewtopic.php?t=21002&highlight=
Cheers

Hi thankyou.
But how the hell do you turn your bluetooth on with flight mode enabled?!?!
It is impossible on a XDAIIi.
UNLESS your using a wired gps receiver?!?!?
SD Card and Formatting
I don't know if anyone is interested but I have done extensive testing on my XDAIIi with my Kingston Elite Pro 512MB SD Card.
Using Spb Benchmark
http://www.spbsoftwarehouse.com/products/benchmark/?en
and softwinter's storage tools
http://www.softwinter.com/storagetools.html
I have tried formatting my SD Card withmany various differnt set-ups.
I.e. differnt cluster sizes, FAT 16 and FAT 32, back-up FAT or not.
And by using the 'storage card' benchmark option on SPB Benchmark I have found that my Kingston Elte Pro card functions best and fastest by formatting it like this...
FAT16
512 byte Sector Size
64KB Cluster Size
Backup FAT - NO.
Hope this helps some people, maybe other people can try with their makes of storage card and post their results.
The next 'best' format was with..
FAT32
512 byte Sector Size
32KB Cluster Size
Backup FAT - NO
Also another observation I made was if you format the card using the first set up but have
Backup FAT - YES
There is a significant decrease in speed operation.
As I said above I format my cards in my XDAIIi or through my laptops media card reader.
Hope this helps!!
Happy testing 8)

SD Card Issues...

I've just bought a 2gb 120x Moby Memory SD for my MDA Compact...and the it does not recognise it.Upon insertion it says it wants to format the card and says it formatted successfully. However I can not find the card in 'file explorer' or 'memory'. When I look in 'About/Version' it says the expansion slot is in use.
After speaking with Tech Support at Moby (Excellent) - We swapped it out for a 1Gb 80x SD card (their own)...and the same problem.
T-Mobile support is ...chocolate teapot comes to mind!
Out of the box rom: 1.01.00 WWE (21/10/04)
Has anyone got any ideas about this one (greatly appreciated)
Regards
Paul
I don't know that I can comment on your specific problem, as I have a cheap 1GB SD card that works without issues. Your ROM seems to be really old, however, and you would benefit tremendously by upgrading to the 1.11 or 1.12 versions (1.11 is extremely stable and seems to be a crowd favorite). I don't know if it will resolve your SD issues, but it should at least improve other aspects of the phone. (stability, call quality, bluetooth functionality, and camera quality)
Little Survey...
Okay...i've upgraded my rom to the imate Jam 1.12 from club imate site on my MDA Compact to see if the SD card problem goes away....NO it doesn't. This is really frustrating...and the JAM rom is not as good as the tmobile one with periodic slow downs and already one reset.
Anyway folks, I want to see if I can get some correllation with rom and SD cards. So a mini survey for you all. If you have a T-mobile (originally) MDA compact and use an SD card let me know:
Current ROM Make?
Current ROM Version?
SD Card Make/Model/Capacity?
Any problems with other SD cards?
I will publish a summary for everyone later.
P
sd card
i don't have a tmobile compact,
rather a qtec s100, although I got a TMobile manual in my box..
anyway, i have a 2gb 150x speed ADATA SD Card and I have exactly the same problem. If you browse this forum you will see there is one or two more other topics about the exact same issue.. dont think its anything to do with a specific vendor pda i.e. o2 / tmobile.... but rather a jam thing.
I don't think they currently recognise the latest sd cards, although, i've been told they do recognise the 2gb ultra disk from moby memory retailing at about £133.
So, we can either wait for the ROM upgrade to include the latest stuff, or swap or sell the cards and buy another one.. i'm probably doing the latter to be honest as i just cant wait.
ANyway, if you do find the problem, please let me know.
Regards,
Bushmen
Current ROM; Original T-Mobile
Other details in sig.
Have SanDisk SD 512mb, 100% fine from day one till now.
They don't seem to recognise the 2gb Moby SD...because that was my initial purchase. Then I downgraded to the 1gb. They are going to send me another 1gb from a different manufacturer. Moby are having a few of these problems cropping up.
P
2 Gb GB SD doesnt works but 2GB MMC works fine... :?
MDA & SD CARD
Original MDA ROM & Radio V1.12
Bytestor 2 x 1gb hi-speed cards, no problems 100% perfect.
256mb Kingston card, today, no problems so far.
transend 1gb high speed no prob
old twin mos 256 mb card had same problem with you. but after i fomatted it with an external card reader and windows, worked perfectly. (this was used for a digital camera before)
hope this helps

Do the cards work fine in a PC card reader?
Does "formatting" on the MDA cause the card to be unreadable on the PC (until you reformat it on the PC)?
If so, these are the exact symptoms found on some early Magicians. If the card works in a PC, then it's a fault on the Jam/MDA, not the card, although the fault does vary by card brand. If you don't get the MDA swapped out, you could end up with it randomly wiping your card. See http://www.expansys.com/forumthread.asp?code=I-MATE_JAM&thread=153
If you don't have a PC card reader to test - get one (make sure it's USB2). Life is not long enough to transfer 2GB by activesync!
Imate Jam
My cards:
Apacer 1gb-no problems
Sandisk Ultra 2gb-no problems
Sandisk 1gb (regular)-no problems
For the moment it looks like if you want a 2gb card that works in your Jam, you'd better get the Sandisk Ultra 2gb.

I can confirm, it works on my HTC Magician too, formated with Fat32 on my PC and pluged into the Magician and have full capacity available! Already filled up with 1.4GB of data (TomTom Maps mostly) Really seems the only 2GB SD card working on the Magician :roll:

1GB Magu SD Card 120x Hi-speed, dint work on MDA Compact.
1GB Magu SD Card 120x Hi-speed, dint work on MDA Compact.
Works fine on PC Card reader. But shows prompt for "Format" on MDA. When formatted, it does not show in File Explorer, but About Box says explansion slot in use. This card works fine on my Orange SPV (1st model).
I am trying for 512MB 60x speed Toshiba card.
Transcend 4Gig works on Jam - WITH SHIM
The JAM is famous for having innaccurate "travel" in its SD contact mechanical design. SD cards that are not thick enough will give this symptom. The fix is to add a "shim" of plastic or paper to the contact side of the SD card.
I use the sticky part of a PostIt note. Cover the entire card area except the contacts at the bottom. Contact side only. The Transcend 4 gig card is too thin, but adding the trusty PostIt fix now allows me to use this huge ($100) card with no problems. Hope this hack fixes your SD issues too - chuse...

What speed SD for the Universal?

I havent looked too deeply into this, preferring to ask like .. So please don't eat me.
Its late and all ..
I'm wondering what speed the SD card reader in the Universal is?
Is it worth spending a little extra on some 60x Corsair SD cards or should I just get the bargain bin stuff since the Universal maybe doesnt have a particularly quick card reader?
Any advice welcome. I plan to use this is a system disk with seperate 512 card for my MP3's and pod casts/documents. THAT will be cheap stuff.
But for the main I need a 1gb system disk for storing apps and system stuff.
Compared to a dedicated USB card reader for the PC, the Universal is extremely slow - I have tested this with my 150X 2GB SD card. So unless you plan on using it with a PC card reader, it doesn't really matter
Accessing the SD card through activesync was at least 10 times slower than the card reader...
I did a small test with Pocket Mechanic.
1. My "normal" 2 GB sandisk gives 0.84MB/sec
2. My super duper Extreme III Sandisk 1 GB gives me a whopping 0.88MB sec.
Nr . 2 card, in my portable, writes files much, much faster than nr.1.
You can see however that in my Jasjar the difference is nearly zero.
I would say: go for the cheapest, but I am not a great technician.
Huib
Thanks guys ..
Very informative and will help me get the right card. ie. the cheapest!

Hi
I have not noticed any difference between a basic Sandisk card and a so called 66x KingMax card when used in the exec.
I do notice a difference between these two cards when using them with my digicam - the multishot mode (2 frames/sec) actually works cause the camera is able to write to the card quickly enough. With the slow card, cam kept pausing to write its cache onto the card.
I am not sure that pocket mechanic tells the truth! Likewise, timing a copy from the internal flash to an SD card is not gonna give accurate results (speed of internal flash may be bottleneck). On Wm2003 devices this was possible cause RAM is loads faster than flash still.
You cant test the speed of the SD reader in the exec over activesync tho!! Its a USB 1.1 device (max 11Mbit) and on top of that activesync treats it as a 10Mbit network card. Max you'll see after overheads is thus around 1MByte/sec

Certainly much better to do it that way.

ok i m having problem to decide as well...
anyone has a more concrete data about this ?
i m thinking whether to choose a normal 66x or 133x ...
getting 2gb sd card.. either transcend or pretec...
by the way exec sd slot is 1.01 or 1.1 specification?
hope someone has a benchmark to share.. thanks
1gb Scandisk does the job for me.
Watched a movie on it the other night, perfect. Plenty fast enough.
Its HTC so you can be assured it will be genius design with cheap crap chipset.
Bit like an Italian sportscar.
get one of those sd-usb card combo's....if u can find one going at a decent price.
saves the hassle of card readers. the LAST thing anyone needs is yet another wire lol

SD card speed with Pocket Mechanic

I have a new Jasjar and the package came with a 2GB SD card. The supplier tells me it should be a 60x card but in Pocket Machanic the benchmark says it is 4x on read and just 0.2x on write.
This is my one and only SD card so I have no others to compare. Is it possible Pocket Mechanic uses a different measurement method and that program just gives low figures for all SD cards? Or is my card really a slow one?
Can someone with PM give me some benchmark figures for their SD card so I know whether I have a slow card or not.
And should I expect a 2GB card to perform more slowly than say a 1GB card?
On my Exec using a 4GB 150X Transcend card, I'm only getting 0.7MB/s read and 0.2MB/s write (benchmarked by PocketMechanic)
Like in most other PPCs and PPCPEs, the SDIO interface is low speed so no matter how fast your SD card can run, you'll be limited to the speeds of the SDIO interface on your Universal.
Good observation O2. Actually I find it a bit surprising the Universal would have a slower than normal SDIO interface. After all it is just about the most expensive (if not THE most expensive) PDA/phone available. I guess I expected better - er, if that really is the cause of our slow SD card performance.
