Has anyone used 2gb or 4gb cards without issues on ANY pocketpc device?
My understanding was the technology is basically the same on 1 and 2gb cards.
But I have read the HP ipaq 4150 and 4155 won't go over 1gb without problems.
I have also read the 1910 won't work either. Anyone confirm if this is the case?Why would this be? It is understood that you can't use 16k FAT16 clusters with 2GB cards, but won't they come pre-formatted FAT16 with 32k or 64k? How can you tell the format? Does it use more power from the device or something?
Do the newer pocketpcs support greater than 1gb? What about 4gb and up?
Devices will need the SD 1.1 standard in order to operate with 4GB SD correct?
Any support this yet?
We have heard of fix programs like-

What exactly does this do?
Also Transcend states-
http://www.transcendusa.com/Support/Search/index.asp
iPAQ h4150/h4155 Secure Digital Card Max Capacity is 1GB.
Others say > 1GB should be no problem on 4155. Is it just certain brands?
I have heard many problems with AData and others. Why is this?
Are some brands not working?
Also, anyone have a clue why 2gb SD is so hard to find locally in the U.S.
Ie: BestBuy doesn't carry it, etc, and they are down to $100 now.
Is either the RiData or Transcend any good?
Also, will there be a performance difference on an ipaq 4155 if a
150x SD is used vs a 133x card? How fast can the device go?
What about when it is hooked up directly to a pc with a card reader.

Hello:
I have several IPAQ PDA's. HX2755, HX2415, and a HW6515 PDA/Phone. The Phone has a built in GPS,
so I wanted to store lots of maps. I bought the Ostia mapping program, and then started looking for a storage device. I finally ended up with a 4GB Transcend SD Chip and a 2GB Sandisk Mini-SD
chip. The 4GB Transcend chip works in all three devices, and the 2GB Mini-SD chip works in the
HW6515. Originally, I purchased a US Modular 4GB SD chip from Tiger Direct, and it wouldn't work.
Be careful of them, if you send something back that isn't defective, they charge you 15%.

Does the formatting contribute to the way a pocket device will recognize a 4gb card? I still want to buy a 4gb card but I have no clue it will work in my ipaq rx1955 and I dont feel like settling for just 1gb or 2gb if later on it comes out that the 4gb will work

I just received an A-Data "MyFlash" 4GB 150x turbo card. Inserted the card into the integrated reader in my Dell Inspiron 700m laptop and the machine became confused and never figured it out (contacting Dell after reader driver update didn't resolve). Inserted the card into my 4150 and voila......the memory of the "storage card" showed 3918 MB. The 4150 recognized it and my newer laptop did not. I tested the card in 4 different readers and all but one recognized it correctly. I've been loading the card up most of the evening and running the installs on my 4150 as I go with no apparent problems.
The card is formatted FAT32, is recognized properly by my 4150, and seems to be running just fine. Cost 58.99 with free 3-day shipping @ New Egg.

I have just bought 4150 and a 2gb sd card and for some reason the data just dissapears from the sd card. I installed TomTom and mp3s on there and they just went randomly, where as using my old 512mb card, everything is fine, can anyone tell me why this happens?

the 4150/4155 definitely supports 4gb cards
at least i have a transcend 150x 4gb sd-card in my ipaq 4150
it works flawlessly and i had not one file corruption or something like that
the card also seems to mount faster than my previous ones so that my system reboots faster and all the icons reload faster etc.
transfer speed is awesome too
in my syndisc card reader i get constant speeds of 9MByte/s while reading & writing!!!!
in fact due to this incredible transfer speed i dont even bother reencoding my movies and dump the whole 700mb chunk on the card
reading speed in the pda seems to be ok too because tcmp does not stutter while playing those big files

thanks for the response and for posting it in pdaphonehome.com. I might have to try it out.

Definitely not. Ignore Raystream's post - he seems to mix up FAT16 and 32. WindowsCE has been supporting the latter since version 2.0 (that is, 1998). It is able to use FAT32 cards. (I've also posted this in the linked thread.)
The question is not about the file system (FAT16 vs 32) but about other factors; this is why I can't really tell for sure whether 4GB SD cards will work in your device or not. Theoretically, it should; in practice, I'm not certain.

I had read that WM2003SE and below are FAT, and that only supports upto 2gb. Is this true?
I read it in the forums on pdaphonehome.

If it is not true and will work I would love to buy this card on ecost: www.ecost.com/ecost/shop/detail~dpno~601848.asp

Huh, quite a few questions [:)]
Yes, many use the 2G card w/o problems.
Where did you read this (URL)? I've scrutinized the iPAQ HQ 4150 forum (http://www.ipaqhq.com/forums/forumdisplay.php?f=30 ) but couldn't find anything like this.
Yes, some seem to have problems. The 1910 is a considerably older and worse device than the 4150, however.
Mot probably, to be able to keep compatibility with older, FAT16-only digicams. However, at sizes like this, cluster sizes 32/64k are very wasteful, compared to FAT32.
With, say, the chkdsk program if your card is your desktop card reader. The first row it returns gives you information on the file system (FAT or FAT32) and the third from the last on the cluster size. For example, with my 1Gbyte FAT16 16k cluster card, it prints the following:
The type of the file system is FAT.
...
16,384 bytes in each allocation unit.
...
while, with my 256M FAT32 Ridata card,
The type of the file system is FAT32.
...
2,048 bytes in each allocation unit.
...
It doesn't display whether the card has a backup FAT table – you'll need more specialized Pocket PC programs (I recommend SKTools) to print it. (Incidentally, SKTools prints everything but the file system. This is why you may need to turn to the desktop-based chkdsk program instead of just using SKTools (or the like) from the beginning. An example of what SKTools displays:
As can be seen, there is no file system type (FAT16/32) info.
Of course, once you know what cluster sizes a FAT16 and a FAT32 card of a given size may use, you'll be able to tell at once what file system it has by only knowing the cluster size. For example, in the cases of the two above-mentioned cards, 2k cluster size is impossible with FAT16 at 256Mbytes (4k is the minimum) and 16k cluster size is impossible with FAT32 at 1 Gbytes. Therefore, you may not need to run the desktop chkdsk program at all once you know the minimal FAT16/maximal FAT32 cluster sizes.
Definitely not. I've done quite much power consumption measurements (please see for examplehttp://winmobiletech.com/CARDS/ on this) and found out that even the worst cards (in the test, the Pretec one) will only deliver a 10-15% battery hit in the worst case – that is, during constant writing to the card. In other cases, you'll see almost no battery life difference.
Definitely – most (all?) of them support 2GB SD cards.
Most probably. As there're no 4+ Gbyte SD cards on the market (the ATP card – see for examplehttp://www.palminfocenter.com/view_story.asp?ID=7877 – will only come later), nothing is known for sure.
According to, say,http://www.palminfocenter.com/view_story.asp?ID=7877 , it will be needed. I'm not sure, though – other sources don't say this for sure.
I don't think so – the standard is very new (see for examplehttp://www.mobiletechreview.com/tips/ridata-SD-CF-cards.htm on this), just a few months old. However, as there're no 4GB cards on the market yet, we will hear more info on this before long.
Dunno – it may be the largest tested/certified card, not necessarily the largest working one. They may have just not tested 2G cards with the 4150. Manufacturers prefer not to publish untested compatibility data to avoid to be sued by consumers [;)]
Probably. If you could post some URL's to these discussions, I'd be veryhappy to compile a conclusion of them.
There're some brands with lower performance. Adata, according to, say,http://www.ppcsg.com/index.php?showtopic=28211 , isn't the fastest card. The Pocket Mechanic benchmark data, however, much be taken with a grain of salt – the becnhmarking method I've described athttp://smartphonemag.com/forum/topic.asp?TOPIC_ID=17921 is far superior and closer to real-world usage.
They're just great.
Very marginal, transfer speed-wise – the difference will only be really visible in a card reader or in a high(er)-end digicam.
Then, the 150x card will be slightly faster.
Please note that you'll find plenty of additional information athttp://smartphonemag.com/forum/topic.asp?TOPIC_ID=17921 – you're strongly encouraged to read the article.
