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
Following are the details of my device
ROM Version : 2.0.6.00 WWE
ROM Date : 06/14/2004
Radio Version : 1.18.00
Protcol Version : 1337.38
ExtROM Version : Diamond 1.2 se
Please help

try to open it with card reader. and back up first.

Any luck?
For some unknown reason my XDA IIi no longer reads the SD card!
In about it says "Expansion Slot : In Use", but explorer can't see it!
Any help please?
Loads of pictures and movies on there too.

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.

New Issue With MiniSD

I have a hermes and there i was using a 2 gb sandisk micro sd card for some 5 month...and recently i brought a trinity and then hence im using that micro sd card with a minisd adapter in the trinity...and for last 1 week it worked flawlessly...last night all of a sudden the minisd card disappeared...no sign of storage card like that there has no card inserted...although in the about window it says expention slot in use..but in memory window no storage card installed!! and resco explorer or any other program cant detect the card...
firstly i thought my card is currupted so i inserted it (the micro sd) in my hermes and it worked there without any glitch...even then i formatted it in both fat16 and fat32 in the pc with a card reader but my trinity cant detect the card....
then i thought my mini sd adapter is broken...so i tried the memory card with the minisd adapter in the nokia 6280 and its working there without any probs....and then i tried the 64mb minisd card that came with nokia 6280 in the trinity and WTF my trinity can detect this card and also working with it..that means the card slot of the trinity is ok...
after all of this experiment then i flashed 3 types of rom in the trinity to see if it can detect the card... one is the lsvw edition with gps...(that i was using for a week before this thing happened) then a original htc rom and the dopod australia rom that my set had when i purched it...but all this three rom has same result...can detect 64 mb card (which is nokia oem minisd) but cant detect the 2gb sacdisk (wich is a micro sd to mini sd converted)...
now do anyone have similar kind of problem...or this is a new issue...i dont have any other card to try in this moment.... just ordered a oem 4gb minisd...will get it in next week...
and finally to let you know that my micro sd card is perfectlly working both in hermes and in nokia with the mini sd adapter and i also did a rough test on it with a card reader in computer with the mini sd converted inserted...and no sign of a probs there...
any comment or suggestion would be helpfull...
and a final thing as i brought it in plan from 3 australuia..and im still in that 14 day period...do you thing if i go to a 3 store and told them the setuation will they replace my handset..??i have the dopod australia rom installed so i dont hink they will be able to detect that i had flased other roms...??
Sajib

Sorry but I disagree. I have been using a standard Sandisk 2GB miniSD for 4 months now without any problem.

i got told it will only support a maximum of a 1gb mini sd?????

Using a 2 GB SanDisk without problems.

I've been using a standard (non SDHC) 4 gb card for 3 months with no major problems. Never had the card 'disappear' completely - only minor file corruption like losing a picture or a ringtone (but it always comes back on soft reset). Only have those types of issues occasionally anyway (like maybe 1 a week - device should be soft reset that often anyway!) Overall, very pleased with the performance of this device.

G'day,
Perhaps you could try formatting the card in the trinity using an OEM tool. My card (1GB Sandisk miniSD) "disappeared" a few weeks ago after using it OK for a month. I used a card reader in my PC to back it up then formatted it using Spb Pocket Plus in the trinity. I was then able to restore the data from the PC using activesync. Worked OK for me and no problems since.
Good luck.

minisd card problem
Dear Customer,
Thanks for your email regarding your P3600.? The issue you describe is something we are aware of and are currently in the process of rectifying.? It seems to be linked in some way to the latest updates to Windows Mobile 5 and as such we have also enlisted Microsoft's help in solving this.? It seems that the device is accessing the memory while it is in an idle state.
We are currently still investigating the matter with the help of our engineers in Taiwan, but in the meantime, to workaround the problem you can set the device to turn itself off after 1 minute in the power options, then let the device turn itself off instead of pressing the power button.
Once we have fixed the problem, I have no doubt it will be released in some sort of ROM update in the near future.
Thank you for your patience in this matter.

Hong Kong's D810 now officially shipped with a 2G miniSD as a gift

Ok,
I also asked HTC europe supoport about the specifications and got an answer per eMail that the P3600 supports mini SD up to 2GB and does NOT support 'ultra' or SD HC-versions.
So perhaps give it a try with a regular (and unfortunately slower) 2GB SD??
S.

A strange developement that i thought better to be share...firstly my 2 gb sandisk micro sd card (converted to mini sd with a adapter) still doesnt work after updating to latest dopod rom and to latest aku 3.3.1 htc rom...setting>memory still says not installed...but if i boot into bootloaded mode and use the trinming.nbh trick to flash my trinity with a nbh file..it does detect the sd card instantly and start flashing without any problem..so it also prove that the sd card slot is ok and it also detect the card in hardware level but it cant recognise in software part...its strange as the same card worked for the 1st 1 week after i brought the d810..!!!!
now does anyone one have more ideas??
and hopefully im getting my topram 4gb card in a days or 2 to test more furthur...in this mean time im really frustated for not able to use tomtom as no space to keep the maps....

Have you reformatted the card using a card reader with XP?
Now...I have maintained many times that my TopRam 4gb works just fine in my Trinity while many others have complained about problems with cards from many different manufacturers, both 2gb and 4gb cards. It may not be just a coincidence that mine has no problems. I always do the WM5 performance tweaks on my devices and yesterday I saw in the Hermes Wiki a reference to a known problem with the storage buffer settings. The fix that it recommends is one of the settings that I always change with my performance tweaks. It cetainly won't hurt, and for all of those people that are constantly complaining about their miniSD cards, maybe you should try it! The other performance tweaks might also help.
Quote from the Hermes Wiki:
Missing/Corrupt SD Card?
This mod seems to make the SD Card more stable, and avoids the problems encountered by some members where the SD Card either disappears or the card 'loses' information until it's ejected then re-inserted.
There are two issues to this. One is that SD Cards that are made in Taiwan seem to have more problems than Japan made cards. Kingston SD Cards are made in Japan, so, they are a relatively good bet. Sandisk and Crucial are made in Taiwan, so seems to have more problems. The second issue is the registry; the default values are just too low.
See:

[HKLM\System\StorageManager]"PNPUnloadDelay" = dword:8196
[HKLM\System\StorageManager]"PNPWaitIODelay" = dword:8196

Yeap i tried that performance tweak in both way increased it to 8196 and also decreased it to 1500 nothing helped..
and sure i did format it with two diffrent card reader and also using some other tools like panasonic sd card formater or hp formatting tools...and just a hour ago i tried pertitioning it into two part 1gb/1gb hermes do recognise the card so do the pc in 2 partition mode but trinity cant detect it even now...
and finally as i told you my trinity detect the 64 mb nokia oem minisd card so i also tried partitioning my micro sd into a single 64 partition to find out if it has something to do with the capacity but same result there...
so im bit of confused here...really confused..

It sounds like you've really tried everything. I don't know what else to say , maybe another card will give better luck?

Ok now there i have just got my 4gb topram card and the best of all is my trinity can detect it and show the size as 3970 mb!!!! hey..at last....even though i didnt test it throughly yet (that will be done in next couple of hour) but im happy that the problem i mentioned earlier with 2 gb micro sd card now seems was related to the mini sd card converter or with the card itself atlist not have to deal with the phone warrenty and stuff like that...
thanks to all who tried to help me out..

hi, pls cd u link the other tweaks u reccommend?

Ordered a Sandisk 2GB Ultra Mini SD card earlier today..
After reading this perhaps a 1GB would've been a safer bet... Still, worth a try. Would prefer to have the complete EU maps on one card.

I had a 4Gb card from Moby Memory- it randomly corrupted data. I couldn't work out if it was the OS, the handset or the card causing problems, but assumed it was the card. They refunded me no problems.
I now have a 1Gb Crucial card- no problems so far. (fingers crossed).
The Trinity does seem to be a bit fussy with spotting cards when you insert them (well mine does!)

I Need
SD/SDHC Memory Card Unlocker.​

I really need a 4GB or more sd card.
I have searched and searched for a solution but there seems to be no clear answer. It would seem that some Trinity users are able to use 4gb and 8gb micro cards with adaptors, but others end up with problems after soft resets, such as the device no longer seeing the sd card, or files becoming corrupted.
SO.... I ask you all:
- Can the Trinity reliably use a 4gb micro card with adaptor?
- Is there a fix or download that actually works to achieve the above?
- If not, is there such a thing as a 4GB mini sd card (not sdhc or micro)?
I have tried using a 4gb micro card with adaptor and after soft resetting my Trinity either fails to see it or the sd card became corrupted. I have read many similar stories and experiences. However, My Tomtom maps are nearly 2gb, so I need a 4gb card at least!!!
I see other xda members using 4gb and 8 gb cards. Please, HOW are they achieving this?
Thanks,
Mattster.

hi Mattster,
best way I can hopefully help to answer your questions is:
1. I have used cheap Sandisk 4 gig micro sd's with adaptor in a few Trinity's with no problems at all.
2. there are 4 gig min Sd's out there - see ebay item 260468007473
3. disregarding that cards usually come ready formatted, I always format myself before use anyway.
I have used the Panasonic Formatter (ver 2.0.03) for some time and it works for me.

Hi Carkev.
Thanks for the advice.
I have looked at the 4GB mini sd. It's from Hong Kong and he has sold "4" to date, so I may wait a little before getting one.
Some Trinity's seem to accept 4GB micro's with adaptor, some don't. The search for the reason or solution has tired me out, so I'm sticking with my 2GB for now. I only needed it for my European Tomtom maps (2GB!) so I'll just stick with UK and Ireland.
Thanks for your reply,
Mattster.

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?

Have you read this Topic? Pay particular attention to Post 6.

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.

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)

SD card NOT reading

I have installed the total commander on my sd card and all of a sudden my card stop reading.i restart the system and then got the message to format the card in order to read it. i did but still card was not reading. i inserted the card in my pc but still the card was not reading. i bring my hd2 to factory settings and then also not reading the card. then i again format the card but of no use. any help from anyone.

same here
i got the same problem recently. my 8gb sdhc stopped working. whenever i insert the card in my hd2 it says the card needs to be formatted before use. when format it says formatted successfully but the sdhc does not show anywhere as if there is no memory card in the hd2. computer also does not detect the card. it is the stock 8gb sandisk sdhc supplied by htc. only been using it for 1 week. anyone else has got this problem? do you know what may has caused this? any help will be appreciated. thanks!

Same problem here,
my (HTC supplied) 8gb SanDisk SDHC card stopped working after about 3 weeks use.. I got "do you want to format the card to make it readable.."
Tried different phone (HTC Kaiser), cardreaders on 2 different laptops, winxp/win7/debian/knoppix even canon photocam.. Several restore programs/format programs.. Even tried putting it in the refrigerator over night..
All no luck.. I gave up! (now missing some nice vids from my son..)
sync my SD card almost daily now..

now many user are getting this problem. i don't know if this problem is with micro sd supplied by htc or the phone itself damaging memory card. what is weird is that it seems only the memory card sandisk 8gb supplied by htc seems to be concerned. i just hope after buying another card it does not get damaged too.

HINT
someone told me to put the card in the digital camera and try formatting the card over there. digital cameras have their own format scheme, but i don't have digital camera........its worth trying it...........people called digi gurus told me about that...........

Another card down for htc hd2
I brought a new card 4gb sandisk micro sd. its gone showing me the same message which i was getting it with my 8 gb card "format the card in order to read it" what is the problem is this a problem with the phone or with the card. it is unbelievable that my new card is also showing the same message. what is going on.
I want to know what is the problem, problem with the phone or with the micro sd card.
this is the second card which got damaged......
exact message """" DO YOU WANT TO FORMAT THIS STORAGE CARD TO MAKE IT READABLE? THIS WILL PERMANENTLY DELETE ANY FILES ON THE CARD. PRESSED YES . THIS STORAGE CARD HAS BEEN SUCCESSFULLY FORMATTED. """
NOW IF WE SEE UNDER SETTINGS SD CARD AND PHONE STORAGE NO SD CARD IS SHOWING OVER THERE.
what is the reason behind it??????????????????
I HAVE JUST TAKEN OUT THE USB FROM THE CHARGER NOT FROM THE COMPUTER AS IT IS CHARGED BY THE USB CABLE.
I am still struggling with the first card warranty from the HTC and now my second card with same message is gone down.

i have a digital camera panasonic dmc-fz28. i did try to format the card with the camera. but this doesn't work. you said you got another card damaged by the phone. i think the problem is with the phone itself then. send the phone to your local dealer for repair and see what they say.

My 1 year old 8GB Sandisk microsd corrupted second time since 2 weeks. It happend after running OPERA 10 installed on SD. My HD2 is running on Energy ROM.

Tried that too.. no luck.. (Canon powershot A430)
Now using an older (got it with my HTC Wizard) sandisk 8gb, working without probs for over a month now.. (backing up a lot though..)

Ok i am having the same issue with my class 10 16GB Kingston. All of a sudden after syncing the memory card failed. The phone recognised another class 2 4GB sandisk and works fine. THIS SEEMS TO BE A PROBLEM WITH THE PHONE. and one which has set me back £70 (Not good at all) and is something that only seem to have happened since the intorduction of the 1.66 rom for me

I had similar problem but there wasn't any message, once I go to photo album the card won't be read and all programs from card can't be run, finally took out all the videos/photos and now is fine, gotta be some software glitch.

happened to me also..i lost photos that i wasnt able to back up yet..do i need to buy a new sd card then? this is really frustrating :,(

I got the same problem with my 8Gb Sandisk SD card. after that i installed another 8gb card (from my nokia 5800) on my phone & its been a month & working fine. I think it happened to me after I installed firefox's fennec alpha on my sd card.

Maybe it has something to do with the CLASS of mSD.
When I received my HD2 I bought a 16GB SanDisk mSD from Amazon, installed it and worked fine for half a year. Just by chance it was a CLASS 2 as I looked up now beeing very concerned by this thread. Now I bought the 32GB mSD from SanDisk (also CLASS 2), copied the contents from 16GB card to 32 GB card and it works flawless.
Now let´s check: was there any one with a bricked CLASS 2 mSD ? Or only mSDs of higher class bricked ?
If so we have to aks some hardware-specialists here wether a class 4 or higher card gets bricked because of faster data throughput since these cards seem to be bricked PERMANENTLY ? There could be several physical reasons: Voltage, Ampere, Controller etc.

I got a bricked 32GB class 2 Sandisk card. It was fresh out of the box and I got an RMA from Sandisk. Awaiting for replacement.
I thought it was just a faulty card off the production line, since my stock 2GB Sandisk card still works fine. It shouldn't have been the phone, should it?

Need help

Ok, now I am pissed. My situation is almost identical as yours - including the loss of my son´s new vids and pics... - and I have the HD2 for almost 2 months now.
Suddenly the 8Gb SDHC stock card just stopped working. It came from nowhere. I found it when I tried to watch a video and the player was not showing it. Then I got into file manager and the storage card was missing... after a soft reset, the appaling msg appeared: "Do you want to format this storage card to make it readable? This will permanently delete any files on the card."
What I did recently: installed uZardWebP and MS-NetC3.5 yesterday. But the SDHC access was alright after that.
I am surprised about how many ppl have been at the same situation.
What the heck is going on? Do you guys know if HTC has ever said something about the subject?
If I cannot recover the content of this card, it will be the first and the last HTC unit I will ever get my hands on. Four years using a Sony Ericsson and a Nokia unit with a SD card and no problems whatsoever.
Occurrence could be considered usual if there weren´t so many incidents like mine.
If someone has ANY idea about recovering the card data I would be very grateful. (although I am hopeless after some reading... ...)
Regards!
HTC Leo (HD2) / ROM 1.66.707.1 (76641) WWE / Radio 2.07.51.22_2 / Manila 2.5.19211619.0 - All stock - device´s never been flashed.

I have lost 2 cards. I haven't changed the rom.
Both sandisk I blamed ebay.
Maybe I shouldn't.

Andrew u.k.: Agreed. Maybe you really shouldn't blame ebay.
So far my card recovery was unsuccessful.
At least I won't need to read a lot to learn how to burn a new ROM as long as I won't use this "Card killer" as a serious gadget after all.

most the time a hard reset fixes it...better then loosing valuable sd info over settting up phone again(just happened to me after loading lots of apps on sd didnt read any sd hard reset and its all normal)
