i have old gene and i use wm6.1 and everything is ok
but suddonly become the sd card unreadable and always ask me to format it
and when i format it i cant see it in explorer
and that massage appare when i put the sd card
(Do you want to format this storage card to make it readable? This will permantly delete any files on the card.
and i select yes
then said
This storage card has been successfully formatted.
but when i go to file explorer
it is not there
by the way my sd card is 2 Gb
Try to format the card on a card reader. If the problem persists, then try another card.
Two possibilities : Either the formatting utility in your rom is not formatting it properly, in that case, format it using a Card Reader as ramerson said, OR The card is probably getting bad due to a bad system area. Its not properly retaining the file system structures created during formatting process and the phone cannot work with this corrupted filessytem.
i tried and use another sd card with deffrent sd card size and i have the same proplem and i use wm6.5 and also the same and wm6.1
I think there must be problem with your phone if it is refusing different cards on different ROMs.
@smb: While some of builds of Wm6.5 have issues with SD card, but such instances are not reported with wm6.1 ?
BTW have you tried to format your card (FAT32) using card reader.
@techmate : Buddy for general use in phone Fat32 is a bad format. It slows down the speed of file access to pathetic levels due to its very small default cluster size of 4096 bytes, or 4 KB. Fat16 is the recommended format for windows mobile, and most other mobile phones.

can anyone please tell me how to format mmc card for xda...there's 3 options in win xp ...fat32....fat...ntfs....i cant format it from the xda , keep getting error code 31.....an error occurred while formatting the storage card folder...........thanks
Try formatting to Fat or Fat 32, however if the xda wont format it there may be a problem, make sure the "lock" switch is in the off position. I have had a problem with sd cards before, what I did was a sd backup from the xda, it then seemed to work ok, just deleted the backup and it worked ever after.
theres no lock switch on the mmc card...i've tried storage tools and flash format...the card must be buggered
i have a different problem, but im sure its connected to the formatting somehow! my card only fills up HALF way!
there is 40% more room availble, all scans prooves this, yet i cant add anything to it, im thinking, its the way its formated, was there a 'directory' limit to how many files that can exist in root?
and wasnt it related to the type of formatting? so my question is...
which format/cluster/ect... is best to fully use a 256 card? and 512/1G.?
Hello,
I actually started a topic last week concerning the same thing. i'm copying bits and pieces of it here; it also helps address your concern about which format to use and the sd card limitations. the first point below address which format you should use for the sd card; in this case use FAT. by the way, i use an sd-card reader (usb plugged) to format the card; it shows up as "removable disk e" in my laptop's window's explorer.
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? i don't really know but obviously using FAT format was the best thing to do, but what's with the other formats?
2 cents worth.
cheers mates

thanks Robson...but i have sent to back for a replacement....i tried it in my reader but the pc could not see the sd card...so i went out and bought a 128mb card while i wait for the new one to come....had no problems with the 128 worked straight away
thanks for the tip - from now on FAT is to be my solution
one more thing to add, I do have 256MB SD card on my XDA I and WM2003, ver 4.0.21
I can use my 256MB card to the full limit, the card has been formatted with CnetX format utility (www.cnetx.com) with FAT16 and FAT32 and apart from the fact that content has been missing from time to time, so I had to re-load the files ... when I locked the card, everything is fine now

monika
today I have tested sandisk 512MB SD card ....
I am allowed to fill it up to the full limit of roughly 484MB
I am curious about the other thing .... buying 512MB SD card for its prce it's almost a rip-off and you get only 484MB in return, 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
I just got a 512 Sd card and my XDA doesn't recognise it.
I also have a 256 card which works fine.
I am thinking maybe I need to flash the ROM but am a little scared of doing so.
The card is working in other devices.
TIA

Same result here. Anybody know what's wrong?
does a flash reader for pc work with the sd ?
format as fat16 or fat32 ?
The Billionton 512mb SD card works fine everywhere else (my desktop, laptops, camera, ipaq 1940 pda, eten p300 pocketpc phone).
re: "does a flash reader for pc work with the sd ? format as fat16 or fat32 ?"
hey mate,
normally i reformat my 512 sd card via the sd-card reader (usb) through my laptop. i once formatted using fat16 and fat 32; i found out that the sd card's memory seemd to be restricted; i could only save files or use up to 300-plus mb. i then tried formatting using the ntfs format and my xda2 didn't recognize the card. i then tried using FAT format and the memory usage went up to 480-plus. i use sandisk by the way, not sure if this is the same as the sd card you have. but i do know that you can't use the entire 512 mb; something to do with the security or the card's internal program to retain files.

have you tried using one of these via XDA ??

or
StorageTools frmo there

it shall do the job, i.e. recover your SD card

Hi all,
I Purchased a 8 gb sd card Class 4, and i used it as a "bootdisc" for flashing my vga bios.
But when i format it back to ntfs, my hd2 doesnt detect the sd card, the weird thing is, Windows had no problems reading it when i put the sd card in the card reader.
I reinstalled several Roms including the standard 1.66.xxx from HTC, but with all roms, it just wont read the sd Card.
please help.
hello,
insert SD card into computer, go to My Computer, right click on the sd card > Format, select FAT32, and format the card. and try to read it in the HD2

Yes right. I think HD2 is unable to read NTFS 'cause its desktop windows file system and not windows mobile.
Alright!! It worked, Much Appreciated.
hi,
i am using htc incredible s.some days ago i tried to make folders in my 8 gb kingston like for movies,songs etc.but to my surprise when i changed from disk drive option to charge only,i culdnot find any video or could play previous videos using mx video player.i again changed the option to disk drive and saw that there was no folder there and lost dir had all the files.any how i changed the card and bought 32gb kingston.but the problem is same.and once this problem araises,i cannot play any video file except which i have made from its camera.i am so depressed here that i am thinking of selling my phone
i am using the stock rom 2.3.5 gingerbread.plz help me out.
no help from any 1
i figured out the problem.but again a little confused.my sd caed doesnt seem to work properly.how to check and fix the sd card?
I think corrupted or "lost" files go in that folder. Did you unmount the card on the PC before switching from disk storage to charge only on android?

I think You may try to use formating tool from this site www.sdcard.org It usually helps with bigger SD cards.
Worth to try I think.
Connect your phone to your computer in mass storage mode, or preferably use a card reader and copy all your data from SD card to a backup folder. Format your SD card to FAT32 with 32kB cluster size. You can use the normal right click>format option in Windows/Linux/Mac. Uncheck Quick Format (in Windows) and let it do a full format. It'll take around 20-30 minutes for a 16GB card. This will fix any filesystem errors that are causing data loss. Once that's done, copy back all your data as it is back to the SD card. Now your card should work fine for a long time. SD cards tend to get corrupted over time, especially with Android, so doing this once in a while is helpful, whenever your card gives you any problem. I have had this same problem a few times and this fixed it for me.
I have data corruption on sd too but it happens often to data of any type/size and I believe that the corrupted data are moved to LOST.DIR They have no extension and cannot be opened or recognized. So I'm losing apps, photos, videos, anything. My device is an LG P500 and the sd card is a Transcend 4gb class 6.
What cluster size do you recommend for a 4 gb sd? 4kb is the default for its size and I believe that 32kb is too much for such a small card.
I want to replace the stock microSD card with a 16GB one I bought. Can someone tell me the correct process for doing this? Is it as simple as copy and pasting everything on the old card to the new card and popping the new one in?
Yes, this will be enough. But I advice to reformat Your new card in PC using FAT32 2kb or 4kb cluster size, this can save lot of space, if card was formatted with 32kb clusters.
That's what I did with my new card. Format fat32, copy and paste all old files, you should be good to go.

1) First you need card reader for easy copy_paste ....insert new card in your device go to setting > unmount sd card and erase/format...it will format your card in default and correct format...
then connect your old card to pc and copy data from old to new
if you have no card reader then ..copy your mobile data from device to pc via usb connection..then remove old card and insert new card ....format new card in mobile ...then copy your data from pc to your new sd card
Thank Me If I Helped You :good:

Is there a downside to formatting with smaller cluster sizes?

Is it better to format the card with my phone rather than with my PC?
Hello, what I would do is before formatting the MicroSD. I would put it into your device and let your device set it up. If it doesn't mount right away, go into your settings and then to Storage and find the MicroSD card then format it that way if you are not experienced. Then it would be safe to copy and paste all the data from the old MicroSD card.
OK, so these are the steps I plan on following. Please let me know if I'm missing anything or doing something wrong.
1) Copy contents of old sd card onto my PC via USB
2) Insert new sd card into my PC card reader and format using FAT32 2kb or 4kb cluster size
3) Insert new sd card into Evo and format
4) Transfer contents of old sd card from PC to new card via USB

There is no downside on flash memory, because it has very fast seek time. The only downside may be is performance drop in very low-end devices because FAT tables become larger and may not fit in memory completely.

So when you say "very low-end devices", that doesn't apply to our Evos right?

Yes, our Evo's is hi-end device with 800mb of RAM. This is more than enough to serve even 0.5kb clusters, but because SD operates 2k sectors it will be not optimal.
But make sure that Your new sdcard have sector-aligned partitions, using for example 4EXT Recovery touch.

Obiously....if you are going to use this card in mobile device then it is best to format the card with that mobile device...better security and fast speed :laugh:
I have a 32 GB card in my device. I copied the data from the old card into a new folder on my desktop on PC.
- After this, I formatted the new card in my phone using the option in 4ext recovery.
- Then i putted the new card in my card reader (PC) and copied the data from my old card (stored in new folder on my desktop) back to my new card
- After all this steps, i putted the new card back to my phone.
Voila, all works well as before...:good:
