Before upgrading to the AKU 3.3, I thought I would re-format my MicroSD on my laptop (Vista) so it will perform in optimal mode (to avoid fragmentation).
So, I copied all the programs, pictures, videos and TomTom maps to my laptop, formatted the MicroSD with FAT format (16k segments).
When I was about to transfer the files back, the copy command complained that the files are too big for the 1Gb SD I had. I was surprised since these are the same files that were on the MicroSD before. I looked at my laptop and I was surprised to see that the total memory of the same files is now 1.3Gb. I assume the copy command added some extra garbage to the files due to segment size of my disk, am I right?
Is there a way to eliminate any extra space added to the files when they were copied to my laptop? I really want all these files back on the MicroSD as they were all on this MicroSD to start with (and I even had few tens of Mb free!)...
Help...
Format it as FAT32....

Hello,
I have 3 items on my plate and I'd appreciate any feedback regarding them:
1) i'm using a 512 mb card; i was having some difficulty because the memory of the card would only go up to around 300. at first i thought there was a problem with the card itself so i had to constantly erase the contents to make mp3s, files, pics, mpegs, etc fit. then i stumbled upon the pc command for formatting disks; there were 3 options to format the sd card: FAT, NTFS and FAT32. when i used fat32; the behavior was the same and the memory usage would only go up to 300 max. when using ntfs; my xda2 refused to recognie the card (it wouldn't show up in the explorer app). when i formatted using FAT, everything was great. i can now use the sd card to it's limits and am no longer restricted to the 300-mb trouble i was having.
question: what's the difference in the 3 formats? obviously using FAT was the best thing to do, but what's with the other formats?
2) i was having some problems with loading up mpegs in the sd card. i created folders (example: mp3s, movies, pics, etc). naturally i placed the mpeg files in the "movies" folder; when i used pocket tv to play them the files were not recognized. when i used pocket mvp video came out but a sign kept flashing "error in audio". when i loaded the mpeg files straight to the sd card (no folders assigned), pocket tv and pocket mvp played them perfectly.
question: anyone else experiencing this and if yes what's the story? the mp3 files are in a folder and i don't stumble into any issues with those items.
3) anyone know of a good vcd-ripper program where i can extract clips or create my own small mpeg files? i'd like to extract some of the more memorable scenes in some movies...rather than waste space by seeing scenes which bore me.
cheers mates

Some hints
Hi,
i also have a 512 meg sd card for my XDA 1, without any problems.
Try to format the card using the storagetools freeware:
http://www.pocketpccity.com/software/pocketpc/StorageTools-2002-4-5-ce-pocketpc.html
I also have mp3's and mpeg's on this card. Make sure that you use the latest version of activesync to tranfer the files to the sd card or use a sd card adapter (i use a pcmcia adapter).
here is how to produce your own media files for the ppc:
http://www.mathiaspohl.de/mda
There are 2 sections, 1st is about "How to create DIVx files" for the PPC, the second one is "How to create media files" (i.e. wmv) for this.
regards, Koponet
Not too impressed with storagetools.
It only detected my XDA-IIs 14MB of ROM and not my 512MB SD card.
maybe you should try ....
format SD card within external SD reader attached to notebook, using some desktop application ... or try using
http://www.cnetx.com/Format/download.asp
and verify SD media for errors ...

FAT (File Allocation Table), FAT32 and NTFS (NT File System) are file systems originally made for disk partitions. FAT (also called FAT16) was the original file system used in DOS and has a partition size limit of 2 GB. FAT32, an extended variant of FAT16, was introduced first in Windows 95 OSR2 and increased the partition size limit to 2 terabytes. NTFS, a totally different file system, was introduced in Windows NT. Unlike the FAT file systems, NTFS has security and transaction rollback features. Random access to a huge file is also more efficient in NTFS. Moreover, while the file size limit on FAT32 is 4 GB, a file on NTFS can grow up to 16 exabytes (16 billion gigabytes).
question to JARGON please
today I have tested sandisk 512MB SD card ....
--------------------------------------------------------------------------------
I have 512MB SD card and am allowed to fill it up to the full limit of roughly 484MB and not 512MB, ok .. it is a matter of formatting plus a consequence of the fact that 1MB equals 1024kB but I am curious about the other thing .... I remember old times back with IPAQ + PCMCIA sleeve with inserted flash card 1280MB of sandisk - the size written on the back of the card WAS EXACTLY matching what PPC2002 was showing .... 1280MB
to me it seems like either different "disk geometry" or disk format - can anyone explain it to me pls

monika
An SD card uses a portion of its memory for its security data. That's why you can't use the entire capacity of the SD card. That's also the reason why an MMC, which doesn't have the SD card's security features, has more available memory than an SD card with the same total capacity.
uuups, you are right ...
according to Sandisk SD card manual
http://www.sandisk.com/oem_sd_memorycard.html
user can access only 940,864 bytes plus 10,240 secure area (which are not accessed by user) ... what a rip-off on 512MB card format .. upppps :wink:

I have a 256MB card, and when I go to start>settings>system>memory, and click on storage card, it says I have a 242.23MB card. I understand this difference, but what I dont understand is this: It says I have 149MB used, but when I go into a file explorer (total commander) and highlight all the files on my storage card, it only accounts for 85MB (with no folders hidden). In memaid, im told i am using 124MB used.
What's going on?
Reformat your SD-card.
Block Size
Files on disk (or storage cards) are stored in blocks. Off-hand I can't remember what the block size would be on a (FAT) storage card, but 4K rings a bell.
Two files can not occupy the same block, so if you have a two one-byte files, they will be using 8K of your storage card (two 4K blocks).
Typically, programs that count files will only be counting the file sizes - so in my example above, that would be two bytes, whereas 8K will have gone from your card.
Usually this makes next to no difference to life. However, if you happen to have lots of smallish files on the card, this can account for some very large differences.
Not quite sure it explains what you are seeing, but I offer it up as a possible reason...
Umm ok. Cheers for the replies. Any other suggestions before i reformat it?
Cheers
Put your card in a cardreader, copy all files to a temp folder on your PC. Format the card an copy all files back to the card.
Few minutes work, probably problem solved.
What other suggestions do you need?
Probably this topic should be in a different place, but In some way is connected to my BA.(Im using xplode's WM6). Ok back to problem. So I have 4gb SD card and I can only copy files on it after format. If I want to add sth on a card files became damaged.(I have only one chance to write files if i want to add sth I need to copy all files back on my pc then foramt card and then copy files back on Card). Problem is connected to my BA because when i copy files on a device and from device on my card(by resco explorer) files are ok(i dont need to format card). So where is the problem??
I wish you understand what I'm talking about
Are you sure you have 4GB SD card and not SDHC? SDHC cards are not supported on BA.
I'm sure. Its weird cause when i copy file from phone memory to storage card files are ok. But whem I'm copying directly from PC to card throug card reader(or wm5torage) files are damaged,unless I make a format but format halps only for one time.
May I know the file system of your SD card?
file system of windows NTFS. System of card FAT32
i had this prob. on my previous card its due to the file format. Beyond 2 gb fat do not works so it goes to fat32 and but these non sdhc card keeps running on fat so this happens. in ideal form the 4gb sd should be 4gb sdhc to work properly.
this causes me to switch to 2 2gb sd card instead of 1 4gb. I also advice u to take backup regularly because u never know when they stop working properly.
so if its file system problem why my 1gb card i working(fat32 as well as 4gb). That could mean that 4gb card is damaged sp why its workin after format and why I can copy from phone without mistakes? Is there any way to change file system on a card? By windows formating i can only format fat32
I just ordered a larger SD card for my G2 (16GB, currently 8GB) and was wondering how I would back up everything on the current card and then transfer to the new card. Would I just connect the phone to my computer and attach as USB storage and copy the contents of the SD card to a folder? Then put the new SD card in the phone and connect to computer as USB storage and copy the backed up content to the new card? Should I consider formatting the new SD card as EXT through CWM before copying back over the data?
Any help would be greatly appreciated.
I have just done this today, I put my old sdcard in a sdcard adapter and new sdcard in a usb micro adapter the copied and pasted all my files from the old card to the new card. you could of course keep the old card in the phone plug in to PC and just put the new card in adapter and transfer that way.
With regards to EXT partition, I don't Really think it is necessary because our phones have a decent internal memory so unless you have hundreds and hundreds of apps stored on your phone I would leave it as it is. Unless there are any benefits to EXT partition that I'm unaware of.
I am guessing if I use the EXT partition type, then it wouldn't be readable on my windows 7 box (is there a device driver for windows 7 that reads ext)? Personally I like being able to take the SD card out and slip it into my laptop with an adapter.

If you partition your sdcard you will still be able to put it in to you pc and read the contents.
I think I'm correct in saying (please correct me if I'm not) when you partition your sdcard only part of it becomes and EXT partition and the rest remains FAT32. for example if you had a 4gb card and you make 1gb EXT partition when you plug the sdcard in to your PC the remaining 3gb would be accessible.
Thanks everyone. I was a little unclear about the EXT partition stuff (and quite frankly, still am) but it sounds like its really not necessary.
After rooting with TouchNooter 2.1.31, including re-formatting my SD Card, I find that I have only 75 megs available on a 2 G card. Running check disk shows a total of 75 megs with no bad sectors reported. Searching the forums indicates this is not an uncommon problem, but I didn't find anything specific to TouchNooter.
One solution suggested for other systems is to copy the files of the SD and then reformat. Is this the correct procedure for TouchNooter?
Another was offered at:
http://forum.xda-developers.com/showthread.php?t=1863222
but, that one has me a tad baffled as to how to find hboot on a NST (and, no, I'm not buying an iPhone).
Bear in mind chkdsk indicates the TOTAL space on the 2G SD is only 75 megs -- it does not show that the SD card is actually has 2G of total space. If it means anything, I used Win32DiskImager to write the .img file to my SD card when I first started the rooting process.
Thanks!
When you write the .img on the card, it creates a 75M partition on your card because it is the size of the image and the remaining space is unallocated, that is why it doesn't show up on windows explorer.
You have to use a partition manager to delete the 75M partition and create a new one with all the unallocated space.
I use MiniTool Partition Wizard Home Edition
Right click on the 75M partition->delete
Right click on the unallocated space ->create
Choose the settings you want for the partition, click OK
Then click apply
That worked exactly as advertised. I had copied all my files from my SD to a backup folder on my computer. Once I resized the partition on the SD card with MiniTool Partition Wizard Home Edition, I put it back in the NST which wanted to format the card. I reformatted, pulled the card, transferred my files back to the SD card and everything worked.
Thanks!
