i have ridata pro 1GB SD Card 66x that is broken, the problem is it can only store 28mb after 28mb it will say that the card is not working properly. can this be fix?
IF you have a card reader/writer, then format it on Windows XP or whatever OS, then go to command prompt and type:
CHKDSK I: /R
(I: is the drive letter of your SD card reader/writer)
The /R option will check the disk for physical errors & replace bad clusters with hidden files, so the device will avoid reading/writing to these corrupted clusters (skipping).
Im glad that there is still a possible solution for my 1GB but why not using pocket pc to format SD? like resco explorer it has a sd format option.
yes you can, but formatting your SD card on Windows make it possible for the File System to locate bad sectors in the SD & mark them in the FAT allocation table as hidden files, so your PPC OS won't get stuck while accessing the bad areas on your SD!
I recommend the Windows format.
Thanks! ill do that! hope it works..
It shall work; because it works with hard drives!
They both have the same storage techniques (clusters, sectors, FAT allocation table, ... ) 8)
i believe there is an app called MMC medic.. maybe it can help you somehow and retrieve some lost files..

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:

Right now its FAT, I never formatted it, I just jammed it into the device.
Should I format FAT32? Anyone know?
TIA.
Best to stay FAT if you format to FAT32 your device may not recognize your card. If you ever do format it - do it on the device using storage tools or sktools.
I've used only one of my two 1gb mini-SD's to hold PocketMusic program files and MP3's. I think it was formatted FAT to begin with, but I was unable to copy more than 400mb to the card until I reformatted it to FAT32. It then loaded up with MP3's and there have been no problems. I did the formatting on the PC, not the MDA.
Any card >2gb will require FAT32 formatting, as 2gb is the limit for FAT16.
hello,
i copied in the morning some folders into sdcard via.. card reader...
then i went off with the card..
on the way.. i found out.. my sd card was empty somehow..
i softresetted, nothing fixed it..
when i refresh and view all files.. i see only strange characters and strange folder names..
and the sizes all together looks like 50 GB.
but in fact the pda tells me.. there is only 1,7 GB free instead 1,9 GB..
my sd card is 150x Adata 2 GB..
how can i fix this .. please help me out.. i dun wanna reformat this card, as i have important files on it.
yup you are the proud owner of a broken partition (very common with Fat16 and mobile devices)
from expereince ive found it happens alot with Fat16 and lots and lots of files (like those found in many of the better games or if you have alot loaded onto the card)
my recomendation is to get to a card reader and get some partition management software ( i like the trial version of Partition manager) and rebuild the partition on the card.
let me know how you go,
You can try downloading PC Inspector File Recovery, and running it on the card. It's freeware, and should work well given your card is formatted with an older filesystem.
http://www.pcinspector.de/file_recovery/UK/welcome.htm
You'll likely have to reformat your card, but at least you'll get your files back. If you do have to reformat, and your device supports FAT32, please format your card in FAT32 instead. It has a higher "tolerance" against this sort of failure.

mmmk with a broken partition you wont have alot of luck recovering file clusters, at the very least you will recover things that look like file.001, file.002, etc as most recovery programs will recover pure clusters regardless on data.
and yes Fat 32 is good but you will still get partition faults if you load too many files onto the card.
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
Hello,
i got my memory card locked on hd2, when i launch hd2 with memory card in it sayes: Storage card not working;
I tried installing "back to the future" rom - installed unlocker - tried unlocking but it sayes it's not locked(probably not recognizing sd), hard reset/reset you phone - result in: instead of showing it not locked - it sayes no sd card found.
All the time in "about" settings the free memory is not more then 30mb(depending on rom) - memory card is 2gb, so it's deffinatelly not recognized.
When i do mass storage via magldr/use adapter for microSD and connect it to pc via card reader - pc states that card needs format, but gives error that it's write-protected(with both protected/not modes on sd) - doesn't allows to format, disk manager/partition magic/partition wizard - show various results, but they cannot format the sd card, eventhough partition wizard shows 1partition only on sd and it's 1,3gb.
Tried formatting with nokia n97 mini - formats successfully, but shows 30mb total and makes it free - after plugging to a pc/hd2 - same results as previously happen.
My thoughts: i have 3 partitioned sd card(dk how this happened) with 30mb/1,3gb/rest partitions, and wp7 sd card unlocker doesn't recognize all partitions and cannot unlock it for me, but i dk why n97 does not format it successfully then :/
Looking forward to hear your thoughts,
Paul
Edited:
and yes, forgot to mention, i have tried mbrclean from both magldr/partition wizard - same result
did you try a program called SDFormatter
there are a few overwrite settings that maybe will work for you.
otherwise i'm wondering if linux would see and correctly reformat the disk for you.
you could run a livecd linux distro that wouldn't even have to be installed on your computer.
good luck
use easus partition manager and delete partitions and use format again
SDformatter - i have been using it all the time, same results with diff settings, easus partition master - same results as with other partition apps - it sees only 30mb partition(as same as n97 mini), currently i'm downloading ubuntu distro and will try partitioning sd card over ubuntu, hopefully it works, gonna post results soon
Ubuntu 11.10 - disk manager shows only 1partition of 32mb - it can't be formatted successfully, mbr partitioning system cannot be applied successfully - only non partition applied - but it still 32mb and hd2 doesn't recognize that 32mb partition, gonna go use hirens boot cd partition apps - if i wont have success with them - probably sd card broken :/
did you try gparted in ubuntu??
sorry this stuff isn't working out
i formated my sd card with nokia n97... everything was ok... Just find some partition manager and format the sd card with it...

i'm having a similar problem...
my 4gb sandisk has been corrupted. it shows as a 30mb in raw format. no tool can format it. i;ve tried gparted, sdfomatter 3.1, hdd low level formatting tool, easus. nothing works.
