memory card problem

Hello,
I have now for one week a MDA Varia V (its a brand of t-mobile, but its a copy of this phone i think...)
I have 1 problem with my memory card, he disapear most of the thime when i reading somthing from it.
So let me explain:
When i put music on my memory card true the phone and i want play the music, after some seconds/minutes the music stop playing and in the music player i get first a message that its searching, and after that i get the message that there is no music (get those message in dutch), when i go look for the memory card, they dont find the memory card.
And somthimes the same problem happend when i connect the phone to my pc and select the "hard drive" function, than i putting somthing on the memory card and suddenly the card is away, and when i transfer somthing i get the message that the hard drive is lost, or somthing.
Have sombody the same problem and know sombody a solution for this.
PS: the memory card was in the box of the phone, and i called for support to t-mobile (there always helping with phone related problems) but after on the phone for almost a hour they also dont know the problem and suggest i go search the internet if there more people with this problem and how they solved this.
Sorry for my bad english

RTFM. Your storage card will not be accessible if you connect to your PC as external drive. This is normal.

Euhm when you cant get to your storage card when you connect your pc to it, how do you put data (songs and so) on tho your card?
wat i forget to say above, when i put the card out and back in, or when i restart the phone, everything is normal again (till the problem start from the binginning)

Let me rephrase...
Your storage card is not accessible on your device if it's connected as external drive to your PC. That is, you can't see the storage card if you browse to it using file explorer on your TP2. But you can see it on your PC's file explorer.

yes thats wat i mean, i go to "my computer" i click on my phone and normaly you see 2 "drives" one with the name "/" thats your local drive and one have the name " memorycard" when i go to memorycard and want put some data on it, 9 of 10 sudenly the memorycard is gone after some thime, so the transfer is failing, when i go back to the phone i only see the "/" drive and the memorycard drive is gone, and the only solution is that i take out the memorycard out and put it back in, or to restart the phone.

Sounds like the issue is with your USB cable. Use the original HTC cable and take care to not touch your device after you plug it in. If you still have problems, then you may have to bring it in for servicing. Perhaps the device's USB slot is faulty.

that wil resolve the problem when conect to the pc, but when there is music on the card and i play it on the phone the sd card is also sudenley away. and when i place the music at the device itself isnt that problem, and i use the same (origanal) cable for this.

I did have about the same problem in that my HTC would 'lose' the card after a certain - variable - time. I did always have to open the backcover, remove and replug the card and it would work again for a certain time (sometimes some tenths of minutes, sometimes a day).
Meanwhile I found a solution that works: Advanced Configuration Tool (Freeware)
http://julien.schapman.free.fr/touchxperience/advanced-configuration-tool.php
In the 'Power Management'-section of this program I enabled the 'SD Memory power management' and since then my HTC didn't 'lose' the card again
Maybe this will help you too for your problem

When i start the program i get a error message and a text saying me that the program need a newer version of microsoft .NET compact Framework.
Where can i install this new version?

have found and installed the 35 version form the microsoft website.
after that i install the program and do the settings you told, restart the phone, but have already the same problem...

It sounds as though you have corrupt files or bad sectors on the SD Card.
Backup all data on the SD, do a full format on pc using default allocation size and copy data back.
This will resolve your issues.

[Q] "SD Card mounted as read-only"?

Hi,
I'm posting this issue second time. I have a class 2 SD card with almost 1700mb of ext3 partition. the problem is that my SD turns to read only when accessing some files from my sd card. it says in the notification SD card mounted as a read only and then say "tap" to resolve the card responded unexpectedly.
tapping on it sometimes help if i remove the files that I was trying to access that created the problem. otherwise it mounts it as read only.

Hi, you sure your card is a genuine one? The problems you are having are identical to what I had. Turns out my 32gb card was in fact an 8gb card, and the problem was when capacity was reached it would go to read only. The only way to rectify this was to take the card out, place it in my PC card reader right click on properties of the drive and run the error checking tool. Hope this helps. Got my money back anyway thought £36 was a bit cheap lol! Try writing a large file to the card using your Computer, this should give you an indication if the card is genuine or not.

Card is genuine. I have placed my card several times in my brothers htc hd and formatted it through windows. its almost 8 gb i checked it on windows. last time I deleted a folder which has wiered name as if the folder was corrupted. I deleted that folder n it was running fine again. but its back again.
mine came with telus, so it should be genuine. what does class signify? like i have class 2, what does it mean?

CLass is the speed of read and writes.
I recently had a problen like this it turned out to be a corrupt file in the .secure folder used for apps to sd.

then I guess its because of corrupt files but why is it so often specially when I copy something from windows.

I had this problem once after disconnecting from a Windows PC, simply connect the sd car directly to a computer and run the windows verification tool, it finds the corrupt file and your sd card starts working again

hey i recently had the same problem ,, but i figured it out and this method should work fine...!!
>First of all you should know how this problem has occurred..??,
well the reason is, we all connect the phone to system in usb mass storage mode ,,but while removing we'll only give safely remove in the system and forget to do the same in the phone ,,,trust me this the core for this problem....sd-card cannot be fully unmounted by system ,,, so you have to manually do this by your phone
so if you are using the sense rom ,,after ejecting the disk in the system ,,,in your your phone's notification area
in ''connect to pc'' menu select charging only .....this will completely unmount your memory card .
>if you are using non sense rom ,,"turn off the usb" mass storage
do this every time you connect your phone to the system ..!!!
ok now solution for your problem..
>reboot your phone to recovery mode using rom manager...
>select partition menu
>now select mount usb storage ,,,
>now you have tow options
1. either you backup every thing and format your sd-card (recommended)
or
2.mount your sd-card and check for errors in windows,,,
this should fix your problem ..
remember ,,next time when you are connecting your phone don't direly unplug the the cable..!!

The Class number represents a multiple of 1 MB/s
So if 2 is written on ur SD card then it means that its capable of a read speed of 3MB/s

- Not always true, its happened to me on several occassions when not connected to PC etc... Flickie HD caused mine
If you have a mac the fix is - disk utilities - repair card
Full format I found to be better though

[Q] Epic 4g Microsdhc issue and One Click Root & Recovery v2.5.5

Hi,
Please forgive me if this is a noob question. I recently developed an issue transferring files to the sd card. Using the usb storage method, after transfering 2 or 3 mp3s, the phone would shut off and reboot for no reason (This caused the Zeam launcher to crash apparently? for at least 15 tries)
I tried using the SD adapter, the transfer rate is extremely slow or to no transfer at all and causes windows explorer to crash or hang (tried at least 15x).
I figured my sd card was corrupted so I tried formatting the card. If I used the SD adapter, it would say the card is write-protected even though clearly, the locked was off. I even tried another SD-adapter to no avail.
Finally, using USB storage, I was able to format the SD card.
Since I mentioned earlier that the Zeam launcher crashed, (yes, I selected always use "zeam launcher" even after it crashed causing the error message to loop) I resetted the phone with the wipe data/factory rest option in clockworkmod (I'm using ViperRom 3.03).
I wasn't sure if the 1 click root (http://forum.xda-developers.com/showthread.php?t=770388) installed any folders into the sd card so I ran the 1 click root in windows just to make sure. After rebooting from the 1 click root, all the files that were previously formatted were back.
I guess I didn't read too clearly but
my questions is
1) how am I able to disable that backup function? I had a bunch of files (which I have no idea what they did) from when i first started playing with the phone and I want to start off fresh with just the files I need.
2) anyone have any idea why the sd card was unable to accept files through the SD adapter or USB storage method?
3) what to do when the launcher crashes (this happened to me 2x already where I lost all my data)
Thanks to anyone who can help. This will help me close some gaps in my limited Android/Epic 4g knowledge.

definitely something is weird. Using usb storage, I ran the scandisk to fix errors and some errors were found. I formatted to ntfs just for kicks and the sd card read blank and in properties the drive had nothing in use. I turned off usb storage, turned it back on and voila, all the files that weren't there are now back. It this a sign of a corrupted sd card or am I going crazy?

Which files/folders are you referring to? Because as soon as your phone mounts your sd card, it will write about 4 folders (I think) if they are not already there...
.android_secure
Android
DCIM
LOST.DIR
if I recall correctly. The other thing you can do is use your phone to format your card instead of doing it on a computer... go to 'Settings->SD card and phone storage->Unmount SD card' then after it is unmounted, use the 'Format SD card' option. If this doesn't work, then you may need a new sd card/phone.

SD Card photo issue

I'm coming from an Epic 4G and after installing Paranoid Android cm10 I'm having some serious issues with photos on my SD Card. Sometimes the gallery finds them, sometimes it doesn't and it appears there are TWO different photo directories, but when I take the SD card out and put it in my computer nothing even shows up in DCIM or Camera.
Any advice? Is everything just going internal for some reason? I can't mount the phone within OSX for whatever reason and when I use my Windows 7 PC(s) it mounts quickly then disconnects. Frustraaaaating.

try this...
1) Dial ##3424#
2) Select PDA
2a) Select Qualcomm USB settings
3) Make sure MTP+ADB is selected
4) Click OK
trying connecting to your PC again.

Bumping this up...
How the heck can I just get my photos (and downloads) for that matter to go on to the SD card by default? Seems like it should be simpler.

[Q] Cannot write to SD from PC!

Hi,
I just got my S 10.5 tablet and loving it so far.
One thing though, I cannot seem to write to my Micro SD card (Samsung 32 GB).
I see it on the table and can format it, browse it.
When I connect to my PC, I see the tablet, as a media device that opens to two drives which are browsable but anytime I just try to create a directory, it hangs...
The behavior is same if I switch to Camera mode.
I tried retrieving and installing USB drivers from Samsung site but changed nothing...
I'm getting desperate... My only option is to remove the SD card, mount it on my phone, transfer my files then back on the tab.... ouch...
Thanks
