microSDHC card reading problems

Hey guys!
Last friday, I finally got my Toshiba TG01, which came with a 8GB Class 4 microSDHC card.
I didn't put it in my phone, since there's a virus on some of these cards!
Now I want to format the card with my Windows XP computer, but when I try to access it with a SD card adapter, it freezes my Explorer...
It gets stuck until I put the card out of it!
I also tried a USB adapter on my Vista PC and it only tells me this:
"Please insert a disk into Removable Disk ( H: )."
Same thing on the XP PC.
Can anyone help me?

sounds like a defect microSD card

Try disabling the autostart feature and then use the Panasonic SD formatting software.

yip know the feeling, the cheap card that came with my HD does the same, although it still works perfectly with my device and is accessable using a/sync.
Going to buy a good make class 6

well id put it in the phone then put the phone into the pc and make it a usb mass storage device
then if it can be seen then awesome format it
the card wont have any affect of the phone its it plugged into the pc as a mass storage device as the phone cant se it

Try reformatting the card, to fat32 using hp's low level format tool it worked for me.

my card is fat32, pc using xp pro still wont recognise it using card reader, although all is fine in disk drive and active sync......no real biggy....

it may be a defective reader

Hi all, just wanted to add something to this, as I have a TG01, and have had a few issues with memory cards with it. This is something I poseted on http://www.modaco.com/content/toshi...5/strange-files-appearing-on-my-storage-card/
"Hi folks, just thought I would update you with a few issues I'v had re the memory cards. I've used the ones supplied by Toshiba, (not the best) but also a Sandisk 16GB and 8GB, and both suffered corruption issues. It took about a hour to copy most of the files over to my laptop, and to do that, I had to put the mem card in my Touch Pro! I'm not sure what this means, as some people have said they have had no issues. It would be interesting to see what proportion of us actually suffer from memory card corruption using other brands! Looks like I may have to carry a backup of my mem card for a while!!... "
I'm not the only the only one with issues, as a few others on that forum have had them too. Wish i knew what was causing it. May have to go back to the old reliable Touch Pro untill we get the promised upgrades?..
Lets hope not.........

nope its not the reader, bought a new one last week as i thought it may have been that. Im sures its something to do with micro sdhc cards and just being made baldy.... cheap is nto always good huh...............
mm thought id add a poll to the thread, would be interesting to see whats the worst offender.......
Let me know if your brands not there, ill add it

Hi, have you already tried this??

chkdsk on wp7

does anyone know of any sort of equivalent to chkdsk for wp7? I've been suspecting lately that the sd card in my focus is partially corrupted (i have issues such as application installations being stuck for hours). of course thats probably just paranoia, cause i've been dealing with some other sd cards that had issues, and it took several formats with several differant programs and i'm still getting errors on them.
when you install an sd card on wp7, does it do a full format? will it detect errors? anyway i can try to fix my sd card?
(of course, i'm not even sure there is anything wrong with it)

Are you using the SD that came with the phone, or one you put in there?
If it's one you put in there, take it out and factory reset your phone.

Your SD card isn't compatible. What you're describing is exactly what happens when you try to use a SD card the phone doesn't like.

I would try a different sd card. the sandisk class2 cards seem to work best.

i'm pretty sure that its is a compatible card. because despite these issues, i've had the card in there for several months and i've never had any real problems (such as a reset)
its a pny 8gb class 4.

The brand and class rating of your card isn't really a good indicator of whether a card is compatible. And the fact that you've had it for a while with no problems isn't necessarily an indicator either, if for a good portion of that time you weren't putting enough data on it that needed to be accessed frequently.
While you will want to stay with something with a lower class rating (like class 2), that still doesn't guarantee compatibility. WP7 needs fast random read and write access. And for the most part, consumer SD cards aren't really tested or optimized for that. In fact, higher class cards are actually optimized for non-random access.
Hardware manufacturers that buy cards in bulk are able to get cards that are tested and optimized for fast random read/write times. At the moment, nobody has been offering those to consumers.
So when you buy a card right now, you're rolling the dice. The cards that haven't been tested to have fast random read/write might still make the grade. But then again... they might not.
So someone who buys a SanDisk Class 2 card might get one that works fine, while another person could get the same card and have it not work fine.

32gb Micro SD card compatability

I have gone through three 32gb cards now and none seem to be working. I try to swap the contents of my 16gb card to the 32gb card and the data gets corrupted each time. The data on the 16gb card is fine and I can transfer it to my PC drive, thumb drive, and even a different 16gb sd card and view all the files with no problem. But everytime I try to transfer it to any of the 32gb cards the data gets corrupted and the transfer fails. I have formatted each card with the panasonic card format software (ver. 3) and it still doesnt work. I have tried different format options and I have even tried to format it with my EVO and still no go. Any suggestions would be appreciated.
Thanks,

The Xoom's SD card slot doesnt work on stock Android 3.0/3.1. If you rooted to get an OS with an operational card slot, it is possible that the root did not install correctly.

Trying to understand...you are saying that the file transfer has failed from 16gb to32gb when using PC to transfer...not a Xoom issue yet? Have you just put a few files on the 32gb card and checked it in the Xoom? It sounds like you've done everything right...are you sure the cards are good?

I am rooted and have been using the card slot for some time.
I have tried to transfer the files by several methods. PC -> Card, PC -> EVO, PC -> card reader, PC -> Xoom, and vise versa. Nothing worked. I have tried putting just a few files on and it seems to work, but when I try to put all the files (about 9gb's worth) the info starts to become corrupt. I suppose its possible that all three cards are bad, but I have to think the odds on that would have been pretty high. The first card was a class 10, the second and third cards were class 4.

I hope someone with experience with a 32gb card jumps on this...I've never used anything larger than 16gb. It just doesn't make sense-have you tried transfering smaller chunks of data at a time? Anyway, I hope you can resolve this...if you do, please share. Good luck!

It really does sound like faulty cards. Where are you getting them from? It's well known that sd cards bought from eBay or Amazon Marketplace are more than likely fake.
For example, I bought a 16GB card from a guy on eBay and was only able to transfer 2GB of data to it then the card corrupted. I later found out that people are re-badging smaller cards to look like bigger ones. They also spoof the size on the card itself so it reports as a larger card when plugged in but they only take up to their former capacity before corrupting.

All were bought from Ebay so that would make sense. Where do you suggest buying the card? My local chain stores do not carry anything larger than 16gb right now.

Yeah, hopefully you can get your money back for them. I did but it took a little nagging.
I buy mine from ebuyer.com but that's a UK site so if you're elsewhere maybe Amazon (direct from Amazon only tho as the Marketplace is just like eBay for fakes) or maybe Best Buy? Definitely go to a reputable dealer anyway.

I either buy mine locally, or NewEgg ONLY.

Hope this helps!

Are you sure your computer isn't putting the usb to sleep while it's copying?

[Q] help!

i got a replacement xoom and when i tried putting in a memory card in it, the memory card would get stuck. i managed to get it in but now it gets super hot when its plugged in the xoom. any reasons why?

I would remove it very carefully but it sounds like something is wrong. One of the metal prongs/leads/whatever on the card may have gotten skewed and could be causing mischief.

actually i think its the memory card cuz i put another one in and that one works and doesnt get hot. by the way the memory card i tried first i had it in my evo and then a few days back i had a notification saying blank SD card, do you think thats the problem?

it sounds like your memory card has either gone corrupt or is trying to. I would suggest backing up your data on that card. I say this because the memory card that I have for my Droid 2 started doing that as well as *uninstalling* all my apps that I placed on the SD card (saying that the files were never there and such, but when placed on my Windows 7 computer, it would be there,) and then would bog my phone down while trying to read the card. I tested to make sure it was not the phone itself (which it would have sucked!) and the same thing happened in two other android phones, proving it was the SD CARD because other (as well as newer too) SDCARDS I had laying around and none of them had this trouble. Even a SD Card testing APP on the market said "Uh yeah... it's dying!"
Because Android is on a linux flavor, it likes to KNOW EVERYTHING on the card or it just does not care for it and then treats it like a blank card. I would suggest that if you want to try and salvage the card, do a quick format AND I WANT TO MAKE THIS CLEAR: to the same file allocation system (aka Fat16 to fat 16, Fat 32 to fat 32, NTFS to NTFS. DO NOT CHANGE THIS unless you know what you are doing!) Also note DO NOT do a full format because this will write to every sector of the SD Card, and that is really really bad for the SD card as well as any flash memory...
A quick format just goes over the file allocation tables (a table that stores information for where the information is located on the card) and then try it again. If problem persists, call manufacturer of the card or where you got the card originally (evo = call htc, droid 2 = call motorola, ETC) and see if it is still under warranty.
Good Luck and I hope I helped you out some

WTF - Warning - SD Card contents

I haven't searched but saying that I've never seen anything like this on Desire or Sensation threads before.
I went to copy something over to the phone (using Windoze Explorer) and when I looked at the contents. I saw the attached. The phone, when I use Root Explorer, and PC agree :-((
For reference I've used Linux, PC (Explorer) and ADB 100% to copy files over successfully before, so no posts about using one or not using one.
All the Filenames etc. have been completely screwed up. Looks like they've been converted to DOS 8.3 format.
I have never ever seen this before. I think I must have run something on the PC when the phone was USB connected. It's about the only thing I can think of, the phone/SD Card/ROM have been 100% reliable so far.
LUCKILY, I made a rare backup of my SD Card yesterday. I usually remember to make one once in a blue moon.
All I can think is to recommend folks to disconnect the USB drive when not needed and do Backups (of the Phone and also the SD Card).
Anyone seen this before ??

sorry to say this to you but your memory card has gone corrupted.
i know this because this has happened to me alot of times.
this happens if you use unbranded memory cards but this also happens to branded memory card.
the only solution i can give to you is buy a new memory card. and the main reason this happen when you connect your phone to your pc/laptop and use it as diskdrive and take the wire out while transferring data.
the only way to prevent is to use a safe remove usb and than change your diskdrive to charge only and wait till everything is loaded and then disconnect your usb wire.
also if you fornat your memory card it will work but i can tell you this that this willhappen again and this could happen without connecting your phone to computer. so to only prevent data loss buy a good new memory card.

Correct me if I'm wrong but I'm 99.8% sure it still works and he doesn't have to buy a new memory card yet .. I don't know where you get the idea that his memory card is completely dead! It looks like he still has his files, there's just all that junk in there! Worse comes to worst, he has to reformat it which I think may not even be necessary
Anyway, I've had a similar situation as yours and "repairing it" fixed those issues up. I didn't even reformat it, just repaired it. Try that! (Assuming you haven't already reformatted it anyway)

Update:
Card is fine. Just the filenames/pathnames got screwed.
As I said luckily I had done a backup of it yesterday, only by accident. I mounted the card on the PC directly (USB adapter) and deleted / copied stuff back.
It must have been something on my PC I ran as it changed the filenames/pathnames to 8.3. I did run something (can't remember the name) as I had problems doing the copy (SD Card to PC) for the backup. A few (4 if I remember) files were too long, exceeded the 255 limit. I D/L something to see what was the issue, turned out to be some book preview I'd accidently down loaded from the market.
All good and working now....
As I said just a warning that **** on the PC can screw the SD Card on the phone.
Backups (Nandroid and SD Card) are a pain but can be life savers.

i don't mean that he should buy a new memroy card because after formating/repairing it the memroy card will work but this corruption can happen again. if this happens again the onl;y thing he can do is buy another memroy card. this has hapened to my unbranded memroy card which was 16 gb class 10 and it happened atleast 5-6 times. since i couldn't take another corruption i have ordeered class 10 32gb lexar memory card which is working fine and its hasn't gave me any problem since i've been using it

Man that's what happened to one of my other 4 gb cards I don't use anymore. It was kinda funny. I ended up reformatting it, but an odd thing has happened... 3gbs went down to 1.7gbs... I can't even access the remaining 2gbs... no matter what I've tried.
I didn't buy a new card since it works just fine. Been using it as a "mini" file storage card for 4 months and no issues yet. =D

You sure everythings fine? A lot of files on that card read "0KB" which is definitely not a good thing.
Best of luck.

Anyone with any issues with an SD card should first attempt a low level format.
I'll leave you all to Google that one.
Sent from my MyTouch_4G_Slide

It's fine.
Just that something I used, never used it before, to check filename/pathname lengths (due to FAT issues), seems to have converted everything to DOS 8.3 format. The ones that didn't conform to that were created after a phone re-boot.
This was only as a warning that **** does happen and backups, while a pain in the arse to do, can save a load of pain.
Off to try some ICS ROMs now so expecting a load more pain, d/l, CWM, Wipe, Swear, revert back to CM7. ;-)))) Just need to make sure that nothing updates my HBOOT..

Try .. A Full format of the SD Card
You need to do a Full format and wipe of the SD Card .. I have " fixed" a few this way.
I use: HP USB Disk Storage Format Tool - Seems to work for me
