sd card not working

Hi,
I need some urgent help...
today i got apacer 1gb 60x sd card.
the card does not allow any write function when it is in my pda2k, thru active sync or thru file explorer on my pda2k,
though it works fine in a card reader, can write and delete on the card.
my older 1gb mmc card is wirking fine in the phone.
i also formatted the card using a card reader, even that does not help.
i tried a format utility on ppc, but that can't do anything on the card, it says the card is read only or the access has een denied,
pls help me!!

I have the same problem and I can not fix it.
I think its the quality of the card.

Same problem here.
For future Reference it is a 1GB, Pretec High Speed

my friend bought 2 cards and sent one to me,
his pda is O2 xdaIIs and mine is imate pda2k, both blueangles..
but the card is working on his pda, and not mine..
hardware is supposed to be the same from HTC...
i fail to understand how can this happen.

Possibly the size of the card, 1gb, is the problem?

FWIW, with regards to size, I use a 2GB Sandisk card in my XDA IIs without any problems.

1gb mmc card is working fine on this phone..
so size should not matter..
i can read the stuff from the sd card... but can not write on it when it is in pda, i'm able to write to it by using a card reader..

Actually I think it may be the speed - 90x on this end

Problems with memory card

Hi all,
I have recently flashed Hypoerdragon III ROM onto my kaiser with success (First time flashing for me). It was working perfectly but later on in the day all my files on my memory card have disappeard. i have now found recovered fragmented files on the memory card which i cannot do anything with, i have run check disk, file scan and tuneup utilities on it but no joy so far.
Anyone have any ideas as i have alot of important files i need to rescue. Its an 8GB SDHC from sandisk if it makes any difference.
Thanks

micro SD smaller than before- ??

hi guys I got weird problem- my micro SD card is, or should I rather say was, 4GB. after some ROM installing I observed that its not a 4gb anymore, but 2gb. and its not about collecting trash, its just maximal capacity. Can some1 tell me what to do?
1. I dont have memory card reader in PC so dont ask me do to that okay?
2. should I do sth before installing new rom? of course HardSPL is done. But between installing 2 different roms? I used to copy the installation file Kovsimg.nbh on card and did standard prodecure- switch off the phone etc but I guess its a mistake isnt it?
thanks in advance

keep the card in your phone and connect to pc with usb cable in card reader mode.
Format card.
If still dont work you got a fake/pirate micro sd

How did you format it ?
On the official SD Association web site http://www.sdcard.org/consumers/formatter/ there is the following statement:
"SD or SDHC memory card file systems formatted with generic operating system formatting software do not comply with official SD memory card requirements and optimum performance may not be experienced."
The site also provide an SD card formatter program, fully compliant with SD Association specifications, but, unfortunately for you, it runs only on PC, so you need a card reader.
I had the same problem some time ago, with a 2GB full size SD formatted with my iPaq and recognized as 1GB, this tool fixed it.

If you connect your device to PC as a card reader, as stated above, it should work.
Go to Settings / Connections / USB to PC and choose Disk Drive. At least, my Xperia, and many HTC have this control panel.

Problem with Micro sd card

I have AT&T Tilt with Sakajati's HyperDragon IV Windows Mobile 6.1 OS ROM, I also have this 8 GB micro SD card, which has around 3.5 GB of data, but for some reason I am not able to write on it any more. When ever I tried to format it I get this message which says " The card is write protected" I don't remember putting any password or anything. I can read data from that card on any computer or phone, but can write anymore data on the card. I can't delete anything from the card either.
Can someone suggest what could be wrong with the card and how can I unlock it?

I have tried low level format also, the format completes without any error, but when see in file explorer all the files are still there. If I try to format from SD formatter, I get error "The memory card is write protected", windows format doesn't give any error, just runs and in the end says "Windows can't comeplte the format". Card is working file and have no problem in reading the data it has, just can't write new one ot delete old one.
This is very weird problem... any help/comment is good.

Not sure if this will help....
I've had very similar issues over time...
Because of high TomTom & Music Use.
Both are loaded and work off my SD Card (6 GB worth)
What I finally found that worked for me, was to get a 2nd card and backing up my SD card to my Desktop PC, so later I could transfer to the 2nd SD Card when needed.
Then I do a Complete Format [Full FAT32 Format] of the old SD Card, via the Mini SD adapter on my Desktop PC.
I found that formating within the phone doesn't always work...
If this is not the case I can think of 2 other reasons for potential problems..
~Some ROM's require the removal of SIM & SD Cards when installing?
~If you were using an adapter formating the SD Card and it was not set to write mode?
Best of Luck!

JAC,
Thanks for your reply, but I have already tried FAT32 formatting using micro sd card, but as I said before, but it errored out.I even tried low level format, but didn't work. There is no locking swithc or anythign in micro SD card, not sure how the data can be locked. If it was ecrypted I was not able to read data on other devices. So what happened? Any help!!!

Like everything else, sometimes things just wear out, break or are just low quality to begin with. If you can read it on other devices, then transfer it and get a new card.

There is also a trick used by nefarious suppliers that takes a 4GB (or any size chip) and format it in a way that it appears as a larger chip. Then when you go to write to it the whole thing goes crazy.
This is why I recommend using reputable resellers and buying good quality Name Brand Chips, Like Sandisk or Kingston.

Master 64 GB MicroSD SDXC unable to format/delete files

Hey guys,
Im new to the forum but ive been following quietly for a while. I thought id make my first post, a new thread because ive been having an issue which i dont know is common or not but has been killing me for the past 4 days and i havent been able to find a solution.
BASICALLY,
My MicroSD 64GB (Master UHS-1 Class 10) has all of a sudden decided not to work on me and here is the problem.
First let me establish a few things.
-> MicroSD reads on any computer (im running mac)
-> MicroSD was formatted on my Xperia Z and has been working for the last 3 weeks
-> I have ejected the MicroSD several times without properly unmounting it from the phone (being honest)
-> Files can be read and copied onto the computer
-> Files can be copied onto the MicroSD but once ejected from the computer and reinserted, the files disappear. Its as if the files that are existing on the MicroSD are locked there forever.
-> Files can be deleted and do appear to have been deleted, however once the MicroSD is reinserted into the computer, (Via usb or SD reader), the files just appear again.
Problems:
-> I am trying to format the MicroSD using Disk Utlilty on Mac but to no avail. i have tried every single option and i have even used SD formatter 3.1 which is a third party program. On mac, all i get is an error saying "Mac OSX was unable to repair the disk" -"you can still open or copy files on the disk, but you cant save changes to files on the disk. Back up the disk and reformat as soon as you can."
-> windows gives me the same error. in windows format. I can do exactly the same i.e copy and paste files onto the MicroSD which disappear, i can delete files which reappear and when i attempt to format using even MS-DOS's "DiskPart" utility, which is supposed to be epic, it still does not work..
I just want to reformat the disk and kill everything on it and return it back to normal.
Ive looked at so many searches and read so many web pages, forums, blogs, everything but i could not find a solid solution. Nothing Works.
MY FINAL PROBLEM!!
Once the Micro SD is placed into the Xperia Z, a message pops up saying "preparing micro SD card.. Checking Errors" This message DOES NOT disappear for hours. ive had it on for half a day and it drained my battery to 26% before i realised that it was killing my battery. it was on standby aswell. I have an old 2GB microsd which i used and the message pops up for about 1 second before it disappears.
This is my problem. I cant use the MicroSD on my Xperia Z anymore. The phone just wont read it. It will prepare it for the next century.
If anyone has any suggestions to how i can get these haunted files off my MicroSD and get it back in working order id really appreciate your help!!
Thanks!!

FAT32, NTFS or exFAT?
Running stock or rooted?
I'm running third party software (paragon), and using NTFS.
17gb bluray movie worked without stuttering, and overall seems stable.
I'm rooted.

Thanks benziii for your reply!
My Xperia Z is rooted and with unlocked bootloader. I think it may have something to do with corrupted files? because of removing the MicroSD without unmounting it all the time perhaps? or i really dont know.
By the way its formatted as MS-DOS (FAT) at the moment =/ cant seem to do anything still. or change it.
Tired formatting in different format with no luck
& im trying to get access to a windows computer atm because i find there are many more third party apps on windows than there is on mac.

My Xperia Z is unlocked and rooted and I am using Sandisk 64gb class 10 sd card and no problems. But its just me! :laugh:

If I were to guess I'd say that the card has been corrupted. It may work with a low level format, or it may not.

1. Removing the card without unmounting it is seriously asking for problems.
2. My Xperia Z documentation says it supports up to 32gb cards. i.e. not 64gb.

Perhaps, but it's doubtful they can do anything you can't do on your Mac or Linux.
On OS X, you can run the following two items from the terminal as root:
1. fdisk
2. newfs ((I assume you want "dos" or "exfat" file system types).
Just, you know, make sure you get the drive right and don't nuke your Mac's hard drive by accident!

I thought max size was 32gb also

Officially it is, but I've seen 64gb cards referenced as working many times. I think it's just a matter of the phone not working to SDXC specifications. Though that's hardly a good reason, as everything else on the phone is first class...

Everyday is a learning day.

It seems your SD card is dead My SXZ broke one SD card (32GB Transcend Ultimate, 10 class) in the first week of using - now it is recognized as 1 GB unknown disk with RAW filesystem. So I had to buy new one (32 GB Sandisk Ultra, 10 class).
My phone just loses SD sometimes and doesn't recognize it till restart. Before installing .434 firmware update I met this problem very often. Now (after installing .434) I meet it sometimes when open stock Camera app. I think that is firmware bug, so waiting for next updates.

I was doing some research and realised that before a MicroSD card dies, it will write protect the data before the MSD card dies so that you can back up any data. you can delete files and copy files but they will autodelete themselves after the card is remounted. thats exactly the problem that i have.. oh well thanks guys. i sent the card back for replacement!! hopefully next one i wont screw over too.
Lesson learnt. never eject sd card without unmounting on phone first!! thanks guys!

Interesting.
I bought a 32GB Transcend class10 MicroSD card from Amazon at the same time as I ordered my Xperia Z.
I did manage to copy around 10Gb of music to it, using Sony Bridge For Mac before it was suddenly 'disconnected' part way through the copy process (I was filling it to 25Gb with music from an iTunes Playlist).
After that I tried it in the Mac directly and a Windows laptop, neither of which would write to the MicroSD card, some of the files could be read, but not many. While SDFormatter claimed to have formatted the card, the files (or their names at least) were still visible, further attempts at formatting the card (with SDFormatter) claimed it was write protected.
Putting it directly into the Xperia Z would cause it to reboot after 2-3 minutes.
I returned the card to Amazon. If it had worked on my Mac (or laptop) I might have kept it, but working on nothing made it useless.
I am currently using an old 8Gb MicroSD card that came with (I think...) the Sony Arc I had a few years back and it seems to work perfectly. I'm loath to buy another 32Gb card to find that it doesn't work.
I assume there is no reason why the Xperia Z shouldn't work with a 32Gb MicroSD card? Do I need to ensure that I get a different class of card, or is a class 10 card suitable? Is it just not compatible with the Transcend card?
Any suggestions you have will be most helpful.

same thing happens to me! files remove and reappear ! "chkdsk /f command" in windows shows that one of my files is cross-linked! here is the message:
\App\install\.goutputstream-5JN7ZW is cross-linked on allocation unit 1181239.
i i tried formatting with windows paragon linux (fdisk,mkfs.msdos,gparted,testdisk...)even i ran windows 98 and ran scandisk for fixing cross-link issue ! but till now no luck.
can anyone help me with this
thanks in advance!

in my opinion there is no way to repair this, just throw it in trashbin.. ive tryd almost all..

I'm in the middle of an RMA with SanDisk right now. It seems that once the sd decides to be read only to protect itself, it's done. Replacement is the only option.
