tyvm

Hi!
Q: Is this affecting every file transferred to the SD card, or just some?
Also, have you still got your phone connected to the PC? Your HD can't read the SD card while the phone is plugged into the USB port. (not sure about bluetooth, since i don't use it) If you open the file manager you will see that the storage device disappears when the phone is plugged into the computer.

well i think i fix it man...format few times my card... with win xp , i have put 1 of new roms and problem solved for now,
otherwise i wass geting problems with diferent kind of files...pictures, mp3s...zip files, w/e and they exist on card but after i try to open, says corupted...

I got same problem.
Moreover, I can't see the µSD card when I plug it into PC !
How do we format the card with PPC ?
---------------------
Edit : solution found : downloaded st.ppc420.arm.cab (storage tool), and suceeded formating my SD card !
Now everything works again : I can use my HD like a USB key again.

well, i use card reader...and on right click u can do that, i hope your card is not dead

well i tho i solved this problem...till now ocurs again, onestly dont know whats the problem...now i got 6.5 mobile, basicly im geting this problem when i try to transfer large files and large zip files like up to 100meg.
anyone got this problem and solved?
ty in advance

[Q] USB Mass Storage mode only for reading ?

I'm the only one having problems with usb mass storage? With all builds from all chef and all kernels it happens the same. I can read from the pc what is on the SD, but if I copy a file Android dont see it , the file size is 0. And new files created in android can't be readed by windows either (I can only read the files that were written on the SD before the last android boot)
I missing something? I tryied dismounting the SD from android with same results
Are you using it in the same way USB MASS STORAGE in WM6.5 ???

I use USB storage all the time and in every andrioid build I've used(about 20) I've never had any problems. There are many people like me that also have no problems, but there are also many like you that have plenty of problems. I'm not sure that anyone really knows why.

Thanks for answering. Do you have 2 partitions on the sd ?

Just want to check a few things:
1: you plug in via usb and select "disk drive"
2: you are not still connected via usb when trying to read the items on the sd card?
3: When you disconnect the usb, you use the usual method (right click the icon in the taskbar and select "safely remove hardware") then wait for the SD card to be prepared by android before accessing it?
Also, how are you accessing the files in Android?

1 & 2: Yes. Windows assing the drive letter and can read it fine.
3: I connect Android to pc, choose USB MASS STORAGE, in windows access the new drive letter, rename a file , choose "safele remove hardware", disconnect the cable, wait for Android to "prepare the sd" , go to the file and it has the old name!!! the weird thing is that if I connect to the pc again, I see in the pc the new name!
Is like Android is working with his own FAT32 table IN MEMORY and not refreshing it.
I tried Ghost Commander/ES file manager/Root Explorer, all with the same results.
PD: I found something else... If I DISMOUNT the SD from Android Im still able to access it with ES File Manager,etc. So its not really dismounting it Why can this be happening with all builds/roms?

I have the same problem. Strange thing is it worked fine fore the first couple of days. Anybody have a solution?

Try using "Rescan Media" app after you copy your files to the SD

Still nothing. I have to boot back into winMo to transfer files to my SD card! This is really annoying,

Plenty of other tools provide media scan as well, like Optimize toolbox, Switch pro widget and more. they all worked for me.
[edit] sorry, optimize toolbox doesn't offer it, it just clears the cache :/
power control plus however has this function as well.

Files on SD card without restarting

Hi at all,
everytime I put files on the sd card, I have to reboot Android because without ES File Explorer won't show the new files I put on the memory card.
Even "Refresh" in ES File Explorer doesn't helo. Is there any other way?
Thanks!

Wifi sync is your friend

This is a well documented problem. I think it's to do with the way that android sees the SD card with booting from it but don't quote me on that. As far as I know, the best ways round it are:
1. Use dropbox. Free 2gb account and can be very useful.
2. FTP. This is my personal favourite. SwiFTP is a free FTP server for android and there are many free ftp clients for PC/Mac/Linux available. I use FileZilla (opensource ftp client).
3. I believe that if you unmount your SD card before copying files over, then remount however I don't find it particularly successful.
There are other ways like shared folders, email files etc but the top 2 above are the best for me. I use dropbox for small files and one-offs or if I'm copying a lot of stuff and don't want to reboot to winmo, then FTP.
It's also worth noting that if you are a windows user then winamp can sync music over wifi providing you install the winamp android client. However both winamp for windows and android are free.
Hope this helps..
enjoy

Ok, thank you. But that's bad.
The problem is not only that I want to put files through USB on it, it happens also when I use CurrentWidget for example that wants to create a log file on the sd card. Hmm...

I use MDJ Froyo HD 4.6, and there are practically no problems when using mass storage option... After unplugging the files are on the SD card... Only sometimes have to reboot, but not very often...

Why so complicated? Use "Multi Mount SD Card" (it´s free) to connect to PC and you will see new files without rebooting.

If you're now saying that applications are unable to create files on the SD then there is something wrong with your card. I'd recommend copying everything off it and reformatting it (use disk management to format it, and use the largest cluster size available).

Some builds suffer from this problem and some don't.
Im using HD2ONE 0.3.6 and it's working fine. File explorer detects the new files after transferring via USB Cable
I love this build paired up with the CM6.1.1 Gingerbread Theme

I've heard many people complain about not being able to see files after copying them across, but I've never heard anyone say that an app could not make a file on the sd card.

I am having the same exact problem. I was transferring files from this PC to my phone and everything was going fine (it refreshes right away after disconnect) then suddenly, my SD Card got corrupted and I was forced to reformat. I used the same ROM (Darkstone's SUPERAM FROYO) and after that, it won't sync anymore. I even tried removing it and using the HD2ONE (mentioned above) ROM and it was the same. I went home, copied everything from my SD backup from the other PC and same symptoms.
I thought I was missing a sync app or something but no. I looked into each of the folders I copied and most of them are blank.
I hope someone can save us!

I find it easiest and safest to just use ES Explorer to access the network shares and copy files wirelessly. The way our data.img is mounted, giving the pc full access to the sdcard is just not a good move. There was good reason when you connected to windows' sync software it disables your phone from accessing the card.
Even though the hd2one build seems to handle it correctly I almost never do it anymore unless it's for big files. It saves the wear and tear on the usb port anyway.

I had that "problem" too, but for me it was easy to solve. Here is the whole procedure:
So, i want some files to put on my sdcard, i plug in the usb cable and select the option "use as a storage", dont check the "use allways" or "dont ask again" (or whatever this is called on your machine). Now the computer "see" the phone and i put my files on it. In this moment i cant browse the sdcard on my hd2, because its reserved for windows now, (thats why currentwidget cant write onto it, same if you have a wallpaper in some "wallpaper" folder on sd).
Now, when i am done, usually i unplug the usb cable for some seconds and then i plug it in again and choose the option "charge only" and the sdcard gets mounted in android like it should and all my new imported files are visible.
Its the same on WinMo, if you choose there the "HDD" option, you cant browse the sdcard on the mobile. Only if you choose "use active sync"(slower) you are able to browse the sdcard.
cheers
ps: the quickest way for me now is to use wifi and shared folders

micro SD. Not showing in file manager [SOLVED]

As the title says. I've put the microsd card of my htc g2/z in the iconia and its working. Though i cant seem to find it anywhere in my file managers. (Music app shows ext. Sd content) tried es and file manager for honeycomb. I want to transfer music and video's over to internal sd. Since acer does not have usb drivers for mac, this is kind off my only option. Right?
SOLVED:
1.
Micro SD card slot shows up under: /mnt/external_SD.
So in your file explorer you have to go to root, and then mnt.
2. There are no mac drivers for the acer A500. You can try http://www.android.com/filetransfer/
Though, that program seems to crash alot!
3.
Transfer your files from mac to A500 using USB sticks, SD cards, FTP servers (loads in market).
USB stick can be found: mnt/external_USB

No it isn't your only option, you install this: http://www.android.com/filetransfer/.

I will check it out. Thanks alot!
**edit**
Android file transfer keeps crashing as soon as i connect the tab. Tried reboot, but still crashing.
Any other solutions? I've tried FTP and such apps. They work, but ofcourse not as fast as usb connection.
and why is my micro sd card not showing in file explorers?

if you're using es strogs file manager than you first need to go to root (click on the left most icon on top) than go to /mnt than /external_sd <-- that's your micro sd card than simply copy and paste your files from there to your internal storage.

Thanks. This makes copying my music alot easier.

Dual File Manager works too. When you start it, just hit the Android back button and you'll see "external_sd"
Sucks that it doesn't mount on my PC though.

I use Winamp on the desktop and the A500. It syncs music from my desktop machine to my tablet automatically whenever my tablet connects to my home wifi.

just put the card in and power down/on the device.

as mentioned, power down fully, not just On/off until the screen blanks. Found out the hard way, lazy person that I am.
Odd thing I've found though is that when connecting my Acer tab to my Acer .... err ... laptop ... feels so incestuous .... is that the mSD card appears as simply "SDCARD" while it's external_SD from the device itself. Ah the sweet smell of O/S kludges in the morning

No need to power off > back on. Just put the sd card in and voila! It worked right away. Just could not find the sd card in ES file. But now I know it's under mnt/external_SD/

actually I wouldn't call it solved, its kind of an annoyance if anything else. Titanium Backup for one won't see it, I thought honeycomb was going to mnt internal as essc (or something like that) and the external sd as sdcard?
You can soft link it (now that we have root) but that won't carry across a reboot for now.
any how still loving this thing!

Cannot access internal memory

I guess this question has been asked several time but trust me..i tried searching through forums but could not find anything that helped
the problem is i can access my phone memory from my PC
i was trying to change my network provider name using this tut >> http://forum.xda-developers.com/showthread.php?t=1038470
it says to replace a file(spn-conf.xml) which resides in /system/etc which i guess is in phone memory...i cannot replace using ES File Explorer(says pasting failed)
wen i try to edit the file it does the same...
So i thot i could replace it from my PC but only SD card appears on PC
here is what i tried
1. tried turning on USB debugging
2. tried re-installing drivers using kies (i did not get the drivers with the phone...only got a CD to install kies)
3. removed the memory card and plugged the phone on PC
i have upgraded to froyo is that what is causing the problem?
i don't remember if it was working b4 i did the upgrade

You cannot access phone's internal memory from a PC (at least not easily). To change files in internal/system memory you can use the "Root Explorer" a paid app, but you can get it for free on Applanet. Then just navigate to a folder and mount it as R/W (you'll see a small button that does this in the top right corner). Or, you can torture yourself with Terminal - first mount your partition as R/W and then cp your files via CLI (commands are identical as in Linux based desktop OS).
