SD Card Slot - General Topics

Does anyone know/have diagrams of how the SD card slot works on an XDAII- ie the locking mechanism and how it detects the presence of a card?
I am asking this as my XDA is only intermittently recognising any SD cards, it formatted a 512mb card and now only 2mb is available to use, I can see the other part of it in the management console but can do nothing to recover it.
After this I bought a new (san disk) card which it recognises sometimes.
Any ideas or information would be gratefully recieved.

unable to use SD card in XDA2s

Hi - I'm a newbie toi the XDA2s & am quite impressed so far but...
Out the box with no card in the slot, it shows a storage card of 43Mb :!: , I assume this is a "virtual" card.
I have bought a 128Mb SD card (Kodak brand) and I can not get my XDA to recognise it at all :evil: - it stubbornly insists I have a 43Mb storage card, but when I hit "settings->about" the display correctly shows that the expansion slot is either "in use" or "Not in use" :?: :!: its just not able to use the memory on the card
I have tried the card in a card-reader attached to a PC and it looks fine, so what is going on?
My OS is Win Mobile 2003 2nd edition version 4.21.1088 (build 14132) and ROM version in 1.31.00WWE date 12/13/04
Hi,
Try (re)formatting in your PC and see if that helps. For 128Mb you probably want FAT16 filesystem with 2Kb clusters. Technically 128Mb is supposed to be 4Kb clusters, but since these things are always slightly smaller than they're supposed to be I'd try 2Kb and see how you go.
You can do this from MS-DOS with:
C:\> format X: /FS:FAT /A:2048
At least that should work (Change X: for the drive letter of the card!)
Hope that helps!
Thanks for the suggestion,
I tried it, but still no luck.
You could also try the "Storage Tools" located at:
http://www.softwinter.com/storagetools.html
You can download for free and although I don't know the limitations are of that version, I know you can format with it, as that's what I did (and all I did).
So hopefully you could format your SD card from their program for the Pocket PC. Just make sure you install the application into main memory since it can't format it if something's using it (although since you can't use the SD card I don't really suppose that'd be a problem!)
I had downloaded pocket mechanic which has a format utility, but this did not help
My issue is Where is this 43Mb card coming from? It is visible and useable whether or not I load my 128Mb SD card. Is there some way of disabling the SDIO port? This may be the problem

quick update:
I've figured out that the 43Mb Storage device must be onboard flash or similar and I have successfully used a 128Mb MMC card 1st time no problem, so the problem is either my SD Card, or my SDIO slot
I have heard that some SD cards are not recognised by PDAs, but the card I am using is happy in my PC. I hope its not the slot
I'm going to try a different SD card (when I can find one to borrow) and I'll post the results.[/u]
OK, so I tried another SD card and it still wasn't recognised; ergo, I have a problem with either the SD Slot, or esle a software config problem
Does anybody have any ideas where I might look to see if I have a software issue?
Thanks
Chris
I think you're looking at the storage folder - not the storage card. The folder is 43mb. If you're looking in system > memory, then change the drop down box from 'storage' to 'storage card'. You should then be able to view the card memory.
Have you tried saving anything in it via file explorer?

Hi JD, thanks for the reply;
I'd figured that bit out once I'd tried using an MMC card. I've renamed the mount point for MMC & SD cards and I can definitely say that MMC cards are fine, but SD cards are simply not recognized at all
I'm wondering whether I have a hardware problem i.e. broken SD slot, or whether there's something that I can look at with Windows i.e. a software config issue
Odd. SD and MMC are interchangeable, although I think MMC cards are slightly thicker.
Possily it makes contact with the card slot contacts when SD cards won't. Which would mean the slot is faulty.
Oh drat I suspected as much, but I thought I'd ask
I'm tempted just to ignore the problem and use MMC cards beacuse I don't want to return my new shiny toy
Thanks
Chris
If it's faulty, I uppose it's possible it will stop reading MMC as well at some stage, If it's stil under guarantee, I'd take it back.

SD cards are thicker than MMC, not vice versa.
Oh. That makes it harder to see why a faulty slot shouldn't be able to read an SD card.
I can't see any other answer though.

[Q] "Damaged SD Card" on HD2 Android NAND ROM

Hi to all
Im having a small problem on my HD2 upon first time boot up from being flashed to CMYLXGO's Stock Desire HD(2).
On the task bar its showing a SD card with a question mark and when i slide the task bar down it says "Damaged SD Card" and that i need to format it, I tried formating it from the phone it self but no luck
Have you tried another SD card yet? Is this your first ROM? Have you put that SD card in another phone, or if not available, an SD card reader? That could help give you some indication as to the state of the card, although I wouldn't rely on that alone to test.
I have toyed around with multiple ROMs on my HD2 and never had an SD card problem, although in the past I have had a card die when doing some modification on my G1. Also, if you are still using the 16gb card that's packaged with the TMOUS HD2, it may be a decent idea to consider replacing it anyway. It's only a class 2 card, and while that may suffice for many operations, it really suffers when you're trying to use an app like QQPlayer to apply software decoding to video.
Okay I found a solution to the problem, I tried using the SD card reader, and it was recognized on the computer, I could read and write from and to the SD card, and this is my fourth to fifth ROM I have tested on the HD2, I been trying to find the best ROM there is for it , and well I just grabbed another SD card that was lying around and.. boom it works im such a noob haha, I didnt think about it until you suggested it, but its still a class 2 SD card. Many thanks
I just had this similar problem with my 16 GB Class 2 microsd Card. Started happening once I created SWAP and EXT2... or 3... (can't remember) on the card for use in Android App2SD. What I did is I formated it in Windows and made sure Allocation size was set to default. Seems to have fixed my issue
Thanks, I fixed the issue now the way you said
The firs step is to download SD Formatter and save the file on your desktop.
Once done, eject MicroSD card from your Android phone and use a MMC card reader to connect it to the computer. You SD card will now be mounted as a flash drive.
Now make a backup of your SD card before proceeding further. You can either copy all folders and file on your SD card and move them to a hard disk folder or use some 3rd party application.
Now launch SD Formatter and click on “Options”.
In options, set Format Type Full (Erase On) and keep Format Size Adjustment OFF. Now press OK to proceed.
After this click on Format and let the application do the rest for you. Please note that Memory Cards with higher capacity will take more time and vice versa. Do not remove your SD card while formatting is taking place because this can permanently damage it.
Once the formatting is complete and you get the success notification, remove SD from MMC reader.
Now insert the card in your phone’s MicroSD slot and wait for damaged SD Card notification in the notification bar again.
Once it is there, simply tap on notification and press format.
Now wait for a minute or two, launch Settings > SD and Phone Storage > and you will be able to see your memory card’s details.
There you have it! You won’t have damaged SD card notification any more and your Memory Card will behave as it should.

I had some problem with the card reader and i accidently removed the card!! Is there any way i could get the card working?

[Q] MicroSD card

Just bought an ASUS HD7 tablet - specs show it will take a 32gB SD. I have a 32gB SD in my Nook Color (CM7) that has a lot of music. Let's bring it over and try that on the new HD7. I unmounted the SD card on the Nook, powered off and powered off the HD7. Inserted the card and powered the HD7 on. After boot, it claimed to be "preparing the SD card for use". I thought, "Great". But, sadly no music. I inspected the SD card with ES File Expl - it identified the SD card but with only 114mB capacity. The card is mounted but shows folders with no files/sub-folders I know are there when in the Nook C.
I pulled out a brand new 32gB SD card - never been used - right out of the blister pack. Dismounted, powered down. Inserted fresh card, powered up, "Preping card - yada-yada". But this time the new card shows an even smaller 96mB capacity.
So obviously I'm missing some key Android-ness point with respect to these cards. Since I've never actually swapped them like this, I'm sort of treating them like a "USB flash or thumb drive" and maybe I shouldn't. Am I just ignorant and missing some sort of prep step or "mount this card" command? Is it possible this reader is defective? (Remember - it recognizes, mounts and unmounts without incident...) Is it a fact that I can independently move these around from device to device in Android even if my versions are different (quite different in fact)?
Any guidance appreciated.

There is no prepping required for Android to recognise SD cards. Usually, they work just as thumbdrives on a PC. The "remove hardware" process should be observed because this will ensure that any cached data will be written to the removable media and that the files are all closed.
With Android, in Settings-Storage, there is a Mount / Unmount. This is similar to add or remove the storage media, eg, SD card.
You can try this workaround. As before, when switched off, insert the SD card to the HD7 and then switch it on. Go to the Settings-Storage and you should see the SD card details. Do an Unmount, remove the SD card, wait a while and then re-insert the SD card and do a Mount. You might be able to acess the data on your SD card by now.
If this still does not work and since you had just bought the HD7, bring it to the seller and have it checked. Also bring along both your SD cards that you had tried to use, as well as the Nook so that you can prove to the seller that there is nothing wrong with the SD cards.

Problems With Micro SD Card On My Samsung Galaxy Grand Prime Plus Phone

Hello:
I don't understand why My phone does not recognize my Micro SD Card. It has been like that since I bought it four years ago. It didn't work with the SD Card that came with the phone, and even when I bought another one it still didn't work. On the contrary, the card is recognizable by my computer, and when I inserted it in to the phone, using a card reader, it was recognized. But when I put it back in to the SD slot on top of the first SIM slot, it doesn't get recognized.
Please what can be done about this problem. My phone storage is already full. It is just 8GB.
Thanks for your anticipated help.
Can you find the menu item of 'Format' in your 'Settings - Storage - SD card'?

Hello:
I've gone through the article you referred me to. The SD card is recognizable on the computer as I did inform you in that post, so I tried reformatting the card.
But when I visited the link on formatting the SD card, I got this message: You don't have permission to access /EN/Fat32Formatter/ on this server.
So, what else can I do.
How can I find the the menu item of formatting my storage settings of Micro SD card.
Try this
SD Memory Card Formatter for Windows/Mac | SD Association
www.sdcard.org
Hello again:
I've formatted my micro SD card with the link you gave me, but the card is still unrecognizable or undetected by the phone. I remember I did the formatting about a year ago.
I am convinced that the problem is a hard ware one, considering the fact that the card can be detected by another phone and the computer. It was detected on my phone when I inserted it in to a card reader and plugged it in to my phone with the OTG cable. But when I put it back in to the SD card slot, it was not detected.
So, the question now is: what can I do now? how can I increase the storage of my phone. My phone internal storage is now full, and I cannot delete any apps.
What other methods can I try out. Or is there a way of fixing the micro SD slot?
The phone came that way. I didn't care to check the SD card slot before the warranty expired.

have you tried going on your Phone setting and searching for the word "SD"
that would show SD card size and option to format it and such
or perhaps have you tried insert other SD card or SD card socket itself has issue?
Inspect the SD bay contacts. Clean card contacts with isopropyl alcohol/cloth and don't touch them with your fingers.
Make sure it's properly seating in the phone.
Try a hard reboot the phone with the card in it.
Try another card.
Whatever app the device uses for storage control check there to see your options.
In the 10+ it's under Device Care>storage>SD card page 3 dots upper right corner.
If it gives you the option to format it, do so. You will lose any data on the card but it should functional then.
It's best to format the card in the device first before using it.

Micro sd not detected in Android phone but working fine in Windows 11

Hi, my micro sd suddenly stopped being detected by phone. Settings app pushed out a notification saying I need to format my micro sd. I tried to format it but it's stuck at 20%. I restarted my phone. Still the same message. I took it out and inserted into card reader and plugged into windows 11 computer. Everythingbis still there. I can still copy and move files of micro SD in windows 11.
2 possible culprits.
1. I restarted my phone
2. I accidentally toggle on "Force allow apps on external" (i have since toggle this off but issue still persists)
How do I fix it so I can use my micro sd in Android phone?
Possible causes for Android not recognizing your SD card:
1. Often, the SD card in the slot simply has no contact with the receiver. Then it is inserted into the device, but can not connect to your Android smartphone. It can then help to remove the SD card once and insert it again. If it clicks into place correctly, the card will either be recognized or there is another problem.
2. The card itself could also be the reason why your Android device does not recognize it. Have you inserted the SD card the right way round? You will usually find a small symbol on the slot that indicates the insertion direction. Another problem could be the write-protect switch of the SD card. It must be deactivated.
3. If you are using an older Android smartphone, the SD card you want to insert might simply be too big. Many older models only support memory cards up to a maximum of 32 gigabytes. Sometimes even only models with up to 16 gigabytes are possible. Information about this can be found in the manual of your Android device. In an emergency, you can also ask the manufacturer directly.
4. Of course, a defect in the SD card is also an option. You can rule this out by inserting your card into another device and testing whether it is recognized. If this is the case, the SD card works.

Hi. Thank you for your response. I did an additional test.
I inserted the card into a card reader then plugged into my phone as otg. It worked fine. Everything was accessible.
So that concludes the card reader slot is the issue. But my question is that the card was inserted in the phone since a long time ago and i never opened the sim tray even just before it started malfunctioning. Is there a possible software issue or it is 100% sure it is a hardware problem?
