Strange, I had about 450 MB of TomTom N5 maps (BNL, D) on my 1GB SD. All used to work fine until I decided to write an additional 350 MB of France map material onto the SD.
Suddenly my TTN5 said it had no maps found. When looking into the
SD card with WM 2003 explorer it showed empty (!!).
But putting the card into the USB SD reader attached to my notebook I could see all files and directories.
Strange. Could it be that WM 2003 cannot cope with +512 MB amounts of data in files and directories. Hard to believe but I'm clueless.
Try to run chkdsk on the SD card (from the PC). Maybe the filesystem got corrupted somehow. If it doesn't work, try reformatting it. If this happens regularly, you could try FAT16 and FAT32, and maybe NTFS (no idea if it supports that).
I've had that on my Magician as well, chkdisk fixed it. It's quite certainly not related to file/directory size (at least on WM2003se), as I've had mp3 dirs way bigger than 512mb and also tried the image version of wikipedia once, which at that time was about 750mb.

Thanks. That was indeed the culprit. I did a chkdsk /F J: and voila, all files and dirs are magically there again.
It is a good idea when copying files to the sd card on your pc via card reader/writer, to right click on the drive/card letter when finished and choose "eject". This flushes the buffers and makes sure that no files are left open and that the FAT is updated.

Yes, that's what I'm usually doing in cases where I write to the SD card when
it is a drive on my card reader.
But in this case I was installing via the USB cradle through the TomTom
CD installer which possibly ill behaves.
Or would I have to "eject" the USB cradle after writing also?
I had the same problem - my SD 512 suddenly becomes empty! No files, but only about 100 Mb free space.
I've format this card and now from time to time make backup by card reader. But still i don't understand why does it happened!
I have this problem on my Wallaby with WM2003SE at least once a month. It's driving me nuts.

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
robson
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
regards,
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
Hi,
I would like to format my micro SD card, but I don't know how to.
I know that there is an option that says " clear storage" but it is for internal storage only ? or can format as well the sd card?
I haven't any card reader on my pc, so I have no idea about how to do it from Hermes itself. .

Keep your micro sd in card reader , you can format it only from pc.(buy one card reader)
if you want format micro sd from device , you need a 3d part application , but from pc is better.

The resco explorer, has a format storage card utility
I have done it already, and works fine.
pocket mechanic works well, also finds errors, cleans up, makes coffee etc
If you're on XP, just right go into disc management, find the card, right click, and choose format...likely a similar method on Vista, but I haven't used it.
No third party tools needed, etc.
Edit, oops my bad, I misread that you didn't have a card reader for the pc.
Another vote for Resco explorer btw, I couldn't live without it.
Well, I got 4GB Micro SD. Formatting (FAT32) done through PC but never been possible through Artemis by any of the softwares mentioned here. The SD works fine under windows, but I gatta take it out in every new ROM or Radio flashing. Is there any way to make it being seen by Artemis DOS system?
Thanks

Delete the folder "MSMETADATA" on your storage card and do a soft reset and that should work
Unless of course the sd card has failed... I had one or two do that... All you have, if the pc won't recognise to format, is a lump of plastic.... You'll have to get a new one...
phone no longer recognizes sdhc card
Okay, guys I flashed my hermes this morning with this
http://rapidshare.com/files/2179382...1.255.1_102_6275_1.38.00.10_108_Ship.exe.html and now it no longer recognizes any of my micro sd nor my micro sdhc cards. They come up on the computer but not on the device. I even installed the sdhc.777 cab and it still doesn't work. Help please...
refuse2bstopped, try a different os... If that doesn't work you may have a broken or misaligned pin in your usb reader on the Hermes. It may also just be dirty or have some corrosion on it. If you want to clean it use a cotton bud and some isopropyl alcohol (surgical spirits). DON'T USE METHYLATED SPIRITS... It leaves a residue.
Cheers...
sir...
im just wondering if my mini sd is busted and it has no use anymore..
why can my camera still recognize that there is still a memory card installed in to my unit that its even asking me to either save the picture's towards my unit or mmc
im just wondering if it can still be recognized by my unit can i still fix it/format it so that i could use it again...??
i know your the expert on this that's why i thought of asking you this..
thanks for reading my msg'
I like to look at things step by step
1. SD card isn't recognised by Hermes - not even detected...
2. Camera detects it - did you try taking a few pictures and seeing if it actually wrote them to the card? I had a phone that registered the card but kept throwing up "sd card corrupt" every time I tried to use it.
3. Does a PC recognise the sd card when inserted into a card reader? If you don't have 1 I'd make this a priority to get, a friend of mine bought one off ebay for $5 AUD including postage...
If the pc recognises it maybe you should reformat it fat32. remember to backup any data first...
4. If the pc and camera have no problem then I'd start suspecting the Hermes... I have two sd cards so I have no problems testing but you may need to either get a smaller card - I use a 512 for flashing the os, or find someone who can lend you theirs to test. If the 2nd card reads then either the card is bung or the Hermes has a problem with it (incompatibility has been known to happen). Clean the card reader as best you can with isopropyl alcohol and a piece of cloth. There may be some type of corrosion or dust on the sd card reader contacts.
These are the steps I have taken to work out if the sd card or Hermes is a fault. Generally I find its the card (happened once to me and once to a friend).
Hope this helps...
Cheers...
Been through this. Very recently, actually. Like, last night.
I don't have a microSD reader and I found myself needing to reformat my microSD in my Hermes to FAT32. I was trying to do SD flashes. Long story.
Anyway, know what I did? I used WM5torage. As long as your ROM is functional and your SD card isn't wasted, activate WM5torage and have WinXP format your "USB Mass Storage Device" for you through My Computer. It only affects the SD card.
I mean, it worked for me.
sd 2gb
i have i sd 2gb card, my pc can see it and use it but only on fat format. i cant format fat32, i get an error(not able to complete). i cant see or use it at all on my phone. (the only selection i have to format (on my pc) is fat,fat32, default unit size)
please help, so i can use the card on my pc and phone
edit:i have searched and the only thing i saw was prog. to format sd, that prog let my pc to see the card, but lost the ability to see it in my phone. (sorry i dont remember what the prog was)
A very good (shareware) 3rd party programm comes from softwinter (storage tools)
rgs
If the PC picks it up, right click on the sd card and select format. Make sure its fat32 though. Easiest thing to do... NO 3rd party apps needed...
i guess i wasnt clear enough. my pc comes up with an error "not able to compleate" when i try to format my card in fat32 (that is when it is in my pc), but i can format fat (but thats no help for me). if i put the card in my device, it doesnt see it, so if i link my device to pc, pc doesnt see the card. so still cant format via pc.
i tried 3rd party as noted, as i thought, if my device cant see it the app cant see it.
thanks for trying, but still in the same boat.
it is a new card too, im woundering if i bought a bum card and i should return it for a new.
any suggestions welcome
Reboot pc then try again... I've had this happen too and a reboot seemed to fix the problem. Just a psychotic computer problem...Sometimes pcs can be..... TROUBLE..
Cheers...
i tried that again, still doesnt work. but i did see autoplay run this time, i think that may be my prob.. 2 progs. trying 2 run on the same source at the same time. now trying to find a way 2 shut it off (like i really need it anyway)
I bought A Sandisk 1GB Mini SD Card off of ebay for $10
-just the the card no card reader, or adaptor of any sort.
I insert it into my wizard, and it fits it with the spring loaded mechnism fine, but when I go to memory managment, im not sure if it knows it's there or not
Memory management will say that, that "external storage": "Not Installed"?
But when I go to take pictures, I go to the utilities/options menu, then general tab, and it doesnt even acknowledge that theres their a card in the slot, only seeing system memory.
So my question is, are their any programs that can/will format my card, or implement something to make it work?
I have Total Commander(not installed), and thinking about downloading this program called "SKTools". Would these programs work.
Cause not only is this a brand new card, but i have pictures and programs that I want to get installed on this device.
-Ive already amazed myself by using the Lockiwiz, to unlock my phone(having only 2-days worth of exp with a smartphone device)
-taken a few pictures, which i have to downloading off my wizard through activesync
-An some other freeware programs that want to install themselves on the system memory
Please help, all/ and any post greatly appreciated
Thanks!
EDIT: I downloaded SKTools onto my device, and its a cool program( I think its a alternate version of total commander but you pay for it?), but it doesnt recognize my Mini SD card either!!
-I also found this program called "WM5Storage", in the description it say that it's specialty is dealing with "external storage", downloading/ and uploading without the need of activesync?
Last edited by projectdarkside(1) : Today at 09:06 AM. Reason: Found new program
I had the same problem.
The only thing that worked on my sd-card was to clean it with an sd-card reader that was pluges in too my computer.
PS. I hope you understand, my english is not so good.
http://pocket-mechanic.en.softonic.com/pocket
got some tricks up it's sleve
jus using card reader to format it to fat 32 format then is ok.
your only option is, which has already be said,is to format the card with a card reader. WM5Storage when activated allows your phone to become a usb storage device that can be plugged into any pc without the need for active sync to be installed. you can then see the contents of the sd card, but as your wizard cant even see the sd card that wont work either,nor will any other program you install.
Either the card is incompatable or it needs to be formatted
The best option to format any SD or MiniSD is into Digital Camera.
Hello all..... just a quick one..... I have a HD2, and have recently found that I cannot transfer files onto the SD card without running the chance of them not actually showing up. Sometime they do, sometimes they don't.
By the above I mean, if I transfer a music folder across which contains a dozen or so mp3..... the transfer appears to happen okay.... the green progress bar on the laptop takes the expected length of time and the folder appears in the directory of the HD2.... HOWEVER.... when I open this folder, the MP3s are not there????
I have had this with some other files (usually larger).... they appear to transfer across without problem, but once I disconnect the HD2's data lead and search through the storage card - nothing there!
I have a HD2, running WM 6.5 on thre latest Vodafone rom, and using an unbranded 32gb sd card.
Any help... VERY MUCH APPRECIATED!!!
I suggest you make a complete back up copy of all the contents of your SD card. hben reformat your SD card using the Fat 32 option. Also I suggest you take your SD card out of your HD2 and put it into a SD card reader and use it to reformat your SD card. All you have to do is find the SD card on your computer by going to My Coputer, it will be listed as a mass storage device or a removable drive. Right click it and select format and use option Fat 32.

First, I would try the re-formatting as discussed in the last post. However, did you try transferring via ActiveSync (assuming you were using the USB drive option)? There are two ways to transfer files on the HD2.
Are those files, by any chance, set to hidden?
If your sd card is an unbranded 32GB one bought from ebay it's most probably a fake...This behaviour is exactly what happens if the fake sd card is 2 or 4GB fooling you to think that it's 32GB one. Any file you transfer that exeeds the real storage capacity of the fake sd card will be lost.

That makes sense.... it was from ebay, and would account for the corruptions and problems which have occured since I swapped it for my 8gb.
I wonder if I have any recourse through eBay?
I've went back to my old 8gb card and everything working fine now.... duff card - confirmed....!
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?
Sent from my Sensation using XDA
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.
