Imate Jamin and 4 gb SD Card issues...

I've just purchased a 4 gb SD card thru ebay, which works fine with my PC, but my Jamin (I've got the latest ROM installed) does not seem to recognize it, wont even show up in file explorer. Does anyone have any suggestions?
Thanks...

I have an 4Gb that work fine with my JAMin but not work fine in my USB Card Reader. Sorry.

Try to reformat the SD card on the PC. I have a-data 4gb, works like a charm, after formating on PC.

Just tried to reformat, but now my pc does not recognize the card...shows an sd card in "my computer", but will not open. Any other thoughts, or did I Just get a bad card?
Thanks again!

Well if it shows up on my computer, but does not open, you should still be able to format it. Right-click and format again using FAT32 full format.
Beyond that I really do not know what could be the issue.

If you have an SD card reader, insert it into your pc and insert the 4Gb SD card.
Then reboot your pc unto the Windows XP setup cd, and choose to install Windows XP on the SD card (should be recognisable). Create a 4Gb (full) FAT32 partition on the SD card. Then just reset to get out, boot normally, and format from Windows.
I found that this method works everytime.

Corrupted FAT Partition

Hi All.
I'm using Cyanogen 4.2.5 with my HTC (rev 32A).
I've 2 4GB sd card (Kingston class 4 and Intenso class 4).
I've partitioned the sdcard and left 3.6 GB as a FAT32 partitions.
Everything goes fine, and i get my android running smoothly.
However, if i connect it to my pc using a usbl cable, if i try to copy a lot o file to the fat partition, let's say 1GB, after 30MB it crashes.
Android becames stoped, the adb lolcat crashes, and after a few seconds, i loose the usb connection.
I restart the lolcat, and i can see that the fat partition gets corrupted and that fsck is running on android ... this is very strange because ti happens with both sd cards.
I've changed the cable, I've tried with windows XP (in different PC's) with linux, etc ...
It just crashes and corrupts the entire fat file system.
If i use a card reader, there's no such problem, in both sd cards.
I hope someone cal help me.
Regards

I just had this same problem. I even went to Recovery and tried to see if it would mount and it said it couldn't mount SD card.
Well, I finally switched usb cables one more time and magically it all works again.. weird huh? Nothing is corrupt... But I think just to be safe I will repartition and reinstall everything.
Correction, my problem was with the G1 sorry. I did a google search and ended up here and I assumed it was a G1 :

[Q] No Sd Card

First i would like to thank you all for some interesting reading
i have just recieved my DHD and love it, my problem is that my sd card shows up just fine on the phone telling me i can unmount it and available space blah,blah, on the same screen when i connect it to the pc running windows 7 as soon as i select disk drive the sd card is un-mounted and then it is not visible in windows explorer also i have removed the sd card and placed it in my pc manualy and sits there looking for drivers
thanks in advance Mick

I assume you have selected "DISK DRIVE" from the drop down list that appears when you connect a USB cable? If so, this is most likely a Windows driver problem. So you might need the HTC drivers.
If you install HTC Sync (found on the card supplied with the phone) that should install the appropriate drivers. If it's not there, go to the HTC website and download latest HTC Sync version.
Can you try a USB stick or a standard card in the card reader of you PC and see if they work?
It could be a faulty SD card, I had problems with the one sent with my phone and had to replace it. All working ok now.

hi thanks for your reply i have done all of the above but still no joy, if the sd card was faulty i would assume it wouldnt work with the phone at all, the only thing i havnt tried is install the htc syn on my laptop to see if its a windows 7 issue or issue with my setup
otherwise i will have to wait and see what htc say about my issue
Cheers
Mick

Wait so let me get this right...
SD card in phone - Works
SD card in phone, hooked to computer using USB and selecting Disk Drive - Does not work (cannot see in Windows)
SD card directly in computer - Does not work...
Sounds like your issue is with Windows, not with HTC or your SD card...
Are you on a work computer by any chance? Can you plug normal USB flash drives in OK?
Either you're missing the Mass Storage driver or it's been disabled on your computer.

External SD Card contents not displayed when I connect tablet to PC??

OK, something weird just started happening. For some reason, my Win 7 PC will not display the contents of my micro sd card when I connect my A500 to my pc. My pc recognizes the connection as soon as I plug it in, the dialog box asking if you want to open the folder comes up, all of the files on the internal sd partition are viewable, but when I click on the ext sd card it opens and nothing is displayed. I took the micro sd card out of the a500 and put it in a usb reader and everything was fine. All files were there and accessible. I even ran checkdisk on it and defragged it. I stuck it back in the a500, rebooted, and connected it to the pc and still nothing is displayed when I click on the sd card. This wouldn't be a big deal but now it makes it real difficult to move any files to my a500 from my pc. I have to copy it to internal memory and then move it to the ext sd using a file manager on the a500. If anyone knows of a solution please chime in.
My a500 is currently running a stock rooted 3.2.1 with all the latest updates installed.

I had similar problem to u except I only had internal storage showing on PC. You can try this - Remove micro sd put it in a usb reader and transfer any file to it, I just used an apk, put it back in tab, connect USB to PC, uncheck USB debugging and you should have access to both internal and external sd.
The weird thing is i'm sure i never had to disable USB debug before I could see external contents. In Device Manager under Portable Devices if USB debug is checked my tab shows up as "MTP" and will not show in win exp. If I uncheck it then it shows as "Acer ICONIA TAB A500" and I can access . Can anyone tell me if this is normal behaviour??? I'm running rooted stock 3.2.1/Win 7. thanks

I had similar problem with no external SD card display when I connected my tablet. Recently, I updated the Android SDK and all of a sudden, my PC displays the external SD card. I am currently using rooted Honeylicious 3.2.1 with the latest recovery RA 3.14

I'll try that, I am running the exact same thing. I have run several roms before going back to stock rooted and I believe the stock rooted was displaying it properly. I can't think of what might have changed on my computer but I will hunt down the android sdk and download it and see if that changes. I have tried several different drivers for the acer with no improvement.

Similar Issue
I have a similar issue. The Music folder doesn't show up, but all the other folders and files are available.

I noticed when I select properties of the sd card in windows explorer it says under file system: Generic Hierarchical. What the hell is that?? Shouldn't it say FAT32?? Also, up on the top or the windows explorer windows when you have details selected under view it has Name, type, size, track number, and artist as the headers. Luckily, I backed up the sd card the other day to my computer so I'm going to take the sd card out and format it and copy everything back and see if that fixes it.

Anybod work out how to fix it I am using stock 3.2.1 and contents of external sd not visable from pc. Internal sd shows contents no problem.

I Think this is a issue due to the original format of the sd card. I to had a similar issue.. I copied everything off the sd card into my pc to back it up.. then put the card into my android phone and formatted it.. Put card back in win7 pc copied files back to card then put it back in the tablet.. CONNECTED usb cable and all is well.. this was months ago. The issue started all at once for me as well. And i do know the card was originally formatted in my pc... This was talked about alot with flashing rom issues as well as not seeing card thru adb..
This is worth a try .. LET me know if it work or not..

no, didn't work for me erica - the weirdest thing is I can see everything fine from my win7 laptop but not on my win7 desktop - until I disable USB Debug then everything is fine??? I think my issue is drivers - i'm loathe to change them tho as it took forever to get ADB working successfully and not too much of a prob to disable USB debug - it would be nice if someone was able to come up with a definitive solution tho

acer uses mtd in order to sync your data. It also allows you the tablet to continue using the internal memory while allowing access to it at the same time. If you are to change it from mtd to a regular drive then the Acer sync will not work and you will lose access to the memory from the tablet while connected to PC.
I believe I read the sdcard slot was only there to allow you to copy items to the tablet. Maybe they changed it with a early update.
When it is in mtd mode the system does not see the memory directly. That is why you do not see fat32. Just Google mtd storage and you will understand.

Can't format my sd card

Hey guys so I tried installing Icecream Tosti's ICS rom v0.6 but it after booting up I saw that the previous version (o.5) was still on the the phone and all my settings and stuff were still there. I had done a fresh install and was confused. So I tried again but it didn't work and when I tried formatting my sd card it wouldn't let me.
I have tried many different tools: Mini tool partition manager, easeus partition manager, hp sd card utility, panasonic sd card formatter, and windows disk management but I kept on getting the errors, can't format. I plugged in the sd card into the computer via a sd card reader and a usb sd reader and even tried different computers but the same error popped up.
Just recently I booted into the rom and plugged in the phone through the usb cable. When I formatted using some of the tools above it showed me the format process was completed, but when I unplugged the phone and rebooted the phone the sd card reverted back to its original state and the sd card was not erased.
Does anyone have any ideas how to fix it? or is my sd card completely gone. I feel like it is just locked and write protected but I don't know how to unlock it since there is no switch on the side. I will really appreciate. Thanks in advance.
