SD card no longer recognized: how to solve problem?

After exchanging from MMC card to SD card the PPC wants to reformat the SD card (the one with all your programs and back up etc on it [1GB]). The other SD card of 256mb is not recognized at all anymore (so much for all my music). Could there be a connection from the fact that I have had a MMC card inserted before? I already have put back the MMC card to see if some program had not been closed properly. ALthough I fortunately have a recent backup of my 1GB SD card ( but not my 256 mb card) I would prefer to find a more sophisticated solution than to reformat my SD card. Who has a solution for me? Thanks.

Is there a bug between MMC and SD?

SD Card getting corrupted by MDA II !!
Hello,
I have MDA ii since last two months and my device has corrrupted my extreme - 512 SD Card Twice and after corruption it's not even recognized by PPC , USB card reader and my camera.
I have installed omeg a_Red OS. on my MDA ii

have you been able to read your SD card at all. I am having the same problem with my XDAIIi. Cannot read the card on any device or PC.

Yep it worked fine straight away, hence I had "Loads of pictures and movies on there too. "
Does any one know what it going on?

maybe the card is dead
seen it happening to a CF card once all of a surden it just died
and would not work in the digicam sdreader ..,....

Nooooo, is that it then?!?! data none recoverable?
Does this happen often? Should I be able to get my money back? What's the point of having 1 gb of storage if at any moment it disapears with all your info on?!

when it happent with the CF card for the camera it was 100% dead and all data was lost
of cause i cant say for sure if it could be saved or not
but no money was thrown after the project
i mean when soo much time have passed who care who was firing the shots from the grassy nole
and to answer you other question then no it should be pretty rare
that a flash card die seen tests where they put a cam on a bridge and blew it up and found the flash card and it still worked
and also this
http://news.com.com/Lost+at+sea,+found+in+flash+-+page+2/2100-1041_3-5780047-2.html?tag=st.num
but i would try some different SD readers before writting it off as dead
i had exp with some sd readers which sucked
and others my own sandisk 8-1 flash reader had no issues reading the card

That's the route I'm trying, installing card reader on pc.
Cheers.
Expect a post in the near future "SD Card reader not working on XDA IIi"
:twisted:

I am also currently in the same soup. Whe I let the xda2 format the sd, it works alright in xda storing files etc, but not recognised by laptop and it also asks to format it.

I am giving up on my card. As it was only 2 days old I am returning it and hoping for a replacement. My friend has sent his XDA II back to O2 as it has destroyed 3 SD cards within the space of two weeks. All different makes. My card was a new 512MB high speed card. I had been using an older Sandisk 256MB card with no problems for several months and decided to upgrade. I will try another card that I have - Sandisk 512MB (slow card) and see if that is OK.
O2 have said that this is not a known problem!!! What do they know???

O2 also gave me the same reply!
Idiots.
Their solution was "Take it to a store, and an engineer will look at it"
Yeah right, you mean a dummy who is trained to follow a 10 stage analysis process and tell you at the end "Sorry, I don't know what the problem is, shall we send it back to HTC for analysis?"
My guess is that the handset is not negotiating the operating voltage correctly, and is frying certain cards.
My 512MB + 1GB Toshiba cards fried within 2 weeks of new.
My 256MB Kingston is still going strong after 9 months (touch wood!)
Now almost 90 quid down the drain, and I'm going to try O2 as a last resort!
(Might print this forum too

This has been happening quite a lot recently. I made a post regarding the same happening to my 512mb Kingston card here:
http://forum.xda-developers.com/viewtopic.php?t=25566
Somewhere in that thread are links to THREE other recent threads regarding fried SD cards. I think there is a hardware fault in the device...

Anyway, I seem to remember the seller boasting about some warranty on their site, so I'm going to try to return it...

I just spoke with the supplier... he was very accomodating. This is what he said:
Whilst the Kingtston card is of superior quality to the Viking they are both using Toshiba components and we have had customers experience a similar issue when using either card with the XDAii where it would seem that the device 'kills' the card... I would recommend a Lexar branded xD card for use in the XDAii rather than any Toshiba based card. If you are interested, you could purchase the Lexar card from us and I can issue you with a full refund for your current SD card (including postage) as I feel the Lexar card would be more suitable for your use.

Problem with micro sdhc

Hi guys! I recently purchased HTC Touch Pro and A-data 8 Gb micro sdhc class 6. My laptop recognizes the card and I format it to FAT 32, so I think the card functions properly. The problem is that the device does not recognize tha card. I updated the ROM with the latest official release from the HTC site , and I was happy finally to see my card. The problem is that after restart, the card is invisible again. Can anyone help me? Maybe the storage card is faulty after all?

Possibly man, i am sure you have another card in there. Test it, if all is ok with it, then exchange your 8GB if possible....

The same thing happened to me; I don't know if it's faulty though. It is recognized at first, and of course I can transfer files from my laptop.

incompatability with SDHC
There is a known partition problem that can destroy your Micro SD (or any other size SD) if you every stuck it into an older reader that does not support newer sizes (any HC, or even standard SDs over 1GB).
Old readers can show your newer SD-family cards, and APEAR to work, until you fill them up past the size the old reader supports.
FOR EXAMPLE:
my old laptop has a built-in SD reader. Back when I used the HTC Wizard, I bought a 2GB miniSD, and dumped files to it from my laptop. Little did I know, the built-in reader only supports SD card up to 1GB. It worked back and forth many times untilI crossed the 1GB line (filled teh SD past 1GB). Then files disapeared or could not be accessed randomly. Kindgston told me it was a known issue of some older devices (readrer/camera/etc): the older device messes up the partition, which you CANNOT fix yourself: reformatting the messed0up partition does nothing. Ship back to manufacturer to fix. Now I'm careful to avoid the built-in SD reader
So I would advise: fill your microSD up aver half-way, and see if you desktop/ laptop has problems accessing files sampled from all over the chip. If it does, this is probabaly your problem.

I think it's just the card/brand itself. The HTC site lists card brands and sizes that have been tested and proven compatible, and the A-Data 8GB isn't one of them (although the 4GB SDHC is compatible). Sandisk is the only 8GB card that's supposedly compatible, and I've pretty much found that out since I had no luck with an A-Data 8GB but the Sandisk works flawlessly.
When I first copied files over to the A-Data and put it in the phone it didn't recognize it at first, but after a couple times of taking it out and putting it back in I was able to read and write to it in TotalCommander, but when I went to play music files the player froze up solid and the card was no longer readable until I did the in and out thing again. Bottom line was there was no way that card was going to work right in the phone, but as soon as I started using a Sandisk I never had a problem.

same thing happen to me
i think the phone will not recognise class 6 memory card
i will try sandisk 8gb class 2 when i got a chance

my touch pro two times had the same problem.The sandisk 8gb microsd HC (class2)collapsed.I can do nothing.My computer doesnt recognize the card.I cannot format it also.Does anybody can help me .What can i do.Thanks.

Card doesn't work in my Fuze. Oh well, I'll find another use for it.

Wierd.... I have two Adata 8GB cards, one works in the Touch Pro, the other doesn't. Both of them work in my Sharp EM One.

hi ive been looking like crazy to fix this problem but this seems to be the only post close to it.
i recently got a transcend class 6 4gb micro sdhc (listed on the website as compatible) for my htc fuze. the fuze (WM6.1) has been updated to the new rom version (5.xx).
i put it in nothing happens. it work fine on a computer (via usb reader). i have a kingston 2gb micro sd that works fine (but is used for another device). I really want to get this one to work so its not a waste.
so far ive tried reformatting to FAT, 64K and FAT32, 32K (via windows vista formatting).. none of which work.
really annoying, i dont have any other device that uses this card and i specifically checked this brand and type with the htc fuze and seems like everyone having no probs with it.
any other things i can try? is it a faulty card maybe (but it works through usb reader)?

I am having problems with the 8gb class6 cards as well. I have tried the Adata and the transcend cards. Here are some interesting things I have found.
1. The energyrom series of roms seems to be the only rom that lets me see the card.
2. I can't access the card until it the rom loads.
3. I can flash roms from the card even if I cant access them from the phone.
I did see there was a utility to help load SDHC cards called SDHC_WM6. I was never able to get it to load right but it indicates there is some kind of software driver that might help these cards.

I saw this utility too.. but its for windows mobile 6 not 6.1.. when 6 came out it had no support for sdhc so that thing came out, 6.1 should have support from the start
of course that didnt stop me from trying it anyway... doesnt work

I have a 8 gb Sandisk- Works flawlessly. I have a 16gb Adata( class 6) that worked for awhile then stopped. Put the 8gb- works, 16gb doesnt. tried different ROM- Still same effect. I has to be the Adata card. I am going to try a 16 gb Sandisk when my funds are available.
Oh- the 16 works fine in the microsd/SD card reader......

SDHC Class 6 works in HTC Jade
I have a jade and both cards that refuse to work with my fuze work just fine with the htc jade. I am not sure if it is a hardware problem or an issue with some software such as the sdhc.dll.
My thought is it is probably software. Why?
First the class 4 cards work just fine. In fact I am currently using a Dane-elec 16gb class4 card.
Secondly I am able to get intermittent class 6 cards access if I use one of the NRGY roms.

I have been using a 8gb Adata card that I bought from newegg, and it has been working flaslessly since november.
I recenlty bought another 8gb Adata from meritline, and this one does not get recognized by the fuze.
I then read in the above posts that somebody used Total Commander to copy files, so I opened up Total Commander, and the card is shown there.
I closed the the program, and now the File Explorer can see the card as well.
Maybe you can try the above steps and see if it works.
edit: actually, I have to plug in and out a few times for the phone to see the card...

I also have this issue with my transcend 8GB class 6 microSD.
HTC Touch Pro (T-Mobile), upgraded to EnergyRom. After upgrade, able to work perfectly. After few hours (the phone of course went into sleeping mode), then the phone was not able to read the card, so starting application installed in it makes the phone hangs.
After a while, the application (10-15 mins) was able to start, then everything is normal again. Very confusing.
At the moment I am assuming it's due to the sleeping mode, somehow the phone (software??) was not able to 'resume' reading from the micro SD.
Note: Previously somehow it clashed with the keyboard mapper software (pro_fuze_keyboard.ZIP), then I uninstalled it, then it was fine. Then I install another version of keyboard mapper (Shlomki TouchPro Keyboard in Fuze ROM.cab), then it's fine again, so I now stick with this mapper. However above issue is still happening.
I read some thread about changing some registry (pnp** set to 8196), so I set it. However still the problem persists.
I haven't tried other suggestion to tweak other registry values. Here's the thread on Hermes device: http://forum.xda-developers.com/showthread.php?t=294324&page=29
I am wondering if it's really class 6 problem. Is there anybody having the same issue with 8GB class 4?
Note: my PC can read the card without any kind of problem.
I put the microSD into N95 also without any problem.

and i have the same problem to touch pro will not recognize my sdhc 4GB class 6, and i have no problems with 4GB class 4.

HI Bobby,
Were you able to get the Transcend 8gb Class 6 work on the HTC Fuze? I have the same problem. I upgraded the rom from the HTC site and I could see it. But later I plugged the card using the adapter to the laptop to copy some files and when I plug that back into the phone, it says "Not Installed". My happiness of not losing 20 buck was only for a couple of mins Any help is appriciated?
Can you give me download link for the energy rom which actually worked with the card?

I had somewhat of a similar issue, wondering if anyone else has seen this?
8 Gig no name brand MicroSD card in my TouchPro, all of a sudden I had less than 1 gig left, using Resco I couldn't see a thing taking up all that space but it was all gone.
I put the card in the transflash adapter and looked at it on my desktop Windows Explorer and saw the following folders in \Storage Card\Program Files
one directory named (*#LD*))#KDP|} with some text after it
another directory named (#*(Y%*(#(*#*(@#kKD* with some text after it.
NEITHER directory could be renamed, moved, deleted, or anything.
Formatting the card hung the format process.
Finally, I put the microSD card back in my TP and all of a sudden Resco Explorer saw these directories and so I just deleted the Storage Card\Program Files directory (no programs in it) and formatted the card and everything was fine.
Anyone else ever seen this?

Storage Card Not Being Discovered

My HD2 either doesn't discover the storage card, or loses it after just a few moments.
I have tried two different cards (the 2GB supplied and my 8GB microSDHC).
Has anyone had a similar problem?
Any ideas?
Or is my phone defective.... Help!

^2 options
either storage card is defective or phone is defective...
seems like you did a cross change...
try another storage card on HD2 and try your HD2 storage card on another phone.
then you know which one causes this.
Usually 95% of the cases its the storage card thats defective

My 8Gb card works in my Xperia X1 - the card is a Sandisk Micro SD HC. Whereas the card supplied is a 2Gb Sandisk Micro SD.
Not sure what HC is.
I assume the HD2 can take a 8Gb card - but unsure about the difference in the cards.

HC = High Capacity IIRC
The HD2 can take an 8gb card.
The cards don't seem to be faulty (that is assuming that you've tested the 2gb also).

Try a reset/hard boot. I have had this issue before with other phones and that sometimes fixes

indeed SD stands for Secure Digital and HC for High Capacity...
the next generation will be SDXC (with eXtended capacity)...but thats coming 2010 or 2011..
anyway seems like your phone has an issue. Because HTC devices of the last few years are all capable of SDHC memory cards and they support either 16 or 32 GB.
I would make use of my warranty. But before try a hard reset.

Thank you all for the information.
The HD2 doesn't like that 8GB SDHC Card. When in the memory section of the phone, it recognises it, displays it used/free space, then shortly afterwards states no card is installed!
A hard reset, if no luck, I'll return it... fingers crossed.

Crap!
Hard reset didn't work! Why do I always get the duff unit!
I find it strange that it detects the card for a while then loses it...
Sending it back tomorrow for exhange....

thats the only reason I'm not such a big fan of online orders...in warranty cases everything takes a little longer.
but don't be discouraged...worse things happen in life. keep your head up

At least in the UK you are covered by Distance Selling Regulations. Hope you get it sorted soon mate!

Did you try to format your SD card?
I faced a similar situation with Diamond 2 where the SD was faulty until I did a quick format Fat32 and it worked perfectly

faced this issue in my touch hd AND x1. try formatting the card - helped me twice.

Did you install SD tune up? I also had the same problem. I uninstalled SD tune up and reset and storage card was found again. also I installed s2u2 but believe it was the former app that caused the problem.

Ah-haaaaaaaaaaa!
Formating to FAT32 has fixed the problem - thank you all for you help and suggestions.
I also must say thanks to HTC tech guru's too who experimented with various memory cards too.
Now to start a new thread on Bluetooth - Car Kit...

I had the same problem with my 16 Gig card. I made a backup of the card on my pc, formatted it and inserted in my HD2 and from that moment I had no problem anymore

HD2 killed my genuine Sandisk 16gb microsd

I did a full reset on my HD2 today, and shortly after my 16gb sandisk ceased to work. I cant even get it to register on my pc... its dead...
Anyone else have this issue?
I'm thinking about trying a kingston card next time...

i have a 16gb sandisk sd and have performed several softreset with no problem for the card.
i don't think your problem is hd2 fault.

I've used many SanDisk cards (including the 16GB) and have not had any problems.
On the other hand Kingston cards have let me down several times.
How long have you had the card?

Yes I have had this happen to me - 16Gb Sandisk - all the same problems as yourself - it's now in the bin.
I got a 16Gb Toshiba & so far so good.

i've got the same problem in my HD2. Mine is 8GB from Sandisk too. But I'd rather think it was the SD's problem, 'cause I bought it at a very low price, it seems like a fake one. lol

I had problems with Kingston, but with SanDisk 16 gb everything is fine. I did soft resets with card in phone, but when I performed hard reset always moved card from phone, and after that restored settings and programs from SPB Backup from sd card. Dont performed hard reset with sd card.

Why not try and repair the corrupt or missing boot sector?
You can find software that will try to repair such problems.
One trick I have used with normal SD Cards that can't be seen on a PC is to insert the card into a Camera and Format it in there.....
I have rectified many a problem disk this way.

Try to reformat the card in a digital camera. I have had cards failing to mount on PCs and Macs but could be formated from a camera. Sandisk in my opinion is the best but it does happen. Safer to remove card before a Hard Reset.

strange.. maybe it's only a case.I'm using adata class6 8gb MicroSDHCs and all works even better as expected!
..or you hd2 is faulty

Yeah i have had this too, Sandisk 16gb failed, would not format, Then my Kingston did it too, formatted in camera and its fine again for now.
Didnt do it in the HD2 though, it corrupted on the pc.
I think the 16gb cards are twitchy.

SD format tool
Sometimes sd cards get fritzed and your pc can't format them, but it still gives it an extension, you can repair them using a different tool to format them. This one's quite popular for that and is used by the guys in some sat nav forums..

Agreed Terry.... It's better known as a corrupt or missing boot sector.
A problem someone may come up against though using this program is that SD formatting is not possible on unrecognizable "removable drives".
So the card may not even be seen.... depending on the level of the problem that is.

Ok.
Same problem here 16gb Sandisk died.
Only thing i did 'special' is connect the hd2 as a removable storage device instead of activesync.
After that the card is dead.
I'm trying to recover the card (i don't think the data is still there)

[Q] Copy error to storage card

Using an HD mini, latest ROM 1.36.401.1 fitted with a 32GB memory card.
Phone syncs fine and I can copy files to the storage card using activesync but as this is very slow with larger files I've tried to use the disk drive mode.
Problem is that the file starts to copy and after a few minutes of transfer I get the error message "The Parameter is incorrect" After this I have to disconnect the phone and reconnect to be able to try again.
It was one of the reasons I bought the phone and added the memory was to be able to load on some video to watch. I use it for music files and sysnc these using media monkey with no problems at all.
Any idea's....?
I checked the HTC site but found nothing, I've also formatted the card in the phone in case it didn't like it being formatted in the PC.

I use a Sandisk 8GB Class 2 SDHC card, never experienced that kind of problem. But I have to say I never tried any files larger than around 1 GB.
What brand do you have? And how big are the files?

The card is unbranded and the video files are 80 - 170MB. I have some other cards so I can try one of them to see if this fixes the issue.

might be the usb data cable ,have you tryed another microusb cable ? or try to load files to microsd using sd-(usb)adapter and see if you still have this error

I tried another cable but the same thing. I've also tried a 1GB Sandisk card as well and that runs with no problems. This unbranded card claims SDHC but maybe it's not high enough quality for the HTC. Wouldn't be the first time a product rejects a certain media.
I've actually just ordered a new Sandisk 16GB class 4 card to try that one out. Should have it early next week and will report back what happens.

Ok, I think if you run a checkdisk on the 32GB card it will report errors. It could be a cheap clone from China, which are known to have quality issues.

Ordered from eBay but a supplier that sells them in original packaging plus gives a guarantee that they are originals.

So received a new 16GB card today, fitted to the phone, copied over some files, so far so good. But then TCPMP would not read the video files saying the MP3 codec is invalid and the other thing I notice is that the storage card is now called Card2. In explorer from the PC it shows two storage cards as:-
Storage card
Storage card2
I seem to be going backwards, powered the phone off/on numerous times, also with the card removed, reformated the card but can't stop it from seeing the card as card2.
Getting so pi$$ed off with this now.

OK a quick update, I fitted the original 1GB card, the phone recognised this as the first storage card and the card2 reference disappeared. I fitted the new 16GB one and all back to normal no card2 issue.
What I don't understand is how it happened and what changed it back. As I intend to load TomTom onto the card the last thing I want is this happening again in the middle of driving.

Never heard of this problem before. Can't think of a cause, maybe something with partitions on your SD card?
