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

no im doing that propertly...removing my HD from USB then im trying to acces filez and i cant...if there is zip file...i see nothing into that folder ( even i see that is proper megabites) or if that is picture...my album says that cant read file ((

[Q] Astro file manager doesnt really do anything?

I noticed that whenever I modified the file system with Astro, it doesnt actually change anything on the sd card. Similarly, whenever I modify the sd card using the usb link the changes dont show up in astro. Im using the latest mattc Android build.
Anyone know what's wrong?

i noticed too lol

I just tried it with other file managers too with the same results. This is definatly not ok. Does anyone have a solution?

Root Explorer. Just now used it to change my boot animation. Word.

I was just about to ask something similar...
Basically, A LOT of it comes down to the Android system doing a "rescan" on the SDcard in order to organize the changes (new files, changed files, etc). This is especially true if you use a USB connection to copy new files (movies, .mp3s, etc) to your sdcard (mount as a disk drive) from something like Windows.
There are apps out there that will rescan your card, but they don't appear to work with the way that we have Android set up on the sdcard.
Other than doing a reboot, has anyone been successful in doing a rescan of the sdcard while inside of Android in order to update the changes?

I have found that when I USB (PC to HD2 (Android), i copy a file from my PC to SD Card while in Android OS, I can see the file on my SD Card with size. However, when I disconnect from USB I cannot install that file (APK) on my HD2. So, I use WM wherever I copy file directly from PC to HD2.
Anyone have any suggestions?
I tried all the file explorers I I think the Root Explorer is the best as it shows all files and has the best/easiest options.

You can either remount the SD card in the settings menu or use the Dev Tools app and tap Media scanner/locater.

Remount doesn't appear to make it work (you'd think that it would, but negative).
I'll try the Media Scanner trick (although I have tried others, maybe this one will work).
Are you able to confirm that this works?

can someone explain the media scanner trick? I dont know what that means..

If you have a ROM with Dev Tools installed (you can also get the APK but this force closes for some.) you can use the Media Scanner item to recreate the cached list of media files on your SD card.
Good luck.

is there a way to put files on the phone and read them without having to restart ?

so is there a way to read the files i have added after i connect my phone to pc as "hard disk " to transfer files ?
every time i add a file, i have to restart the andriod "phone" for it to see it.
if i try to remove the SD card while andriod is running. it will hang and i will have to restart.
is there some other things that can be done? like. media scanner for example.. will it work ?
thanks

Have you tried unmounting and then mounting the SD card? I don't know if it works or not, but it's worth a try.

In my build all i have to do is clicking "enable usb storage card" when plugging in pc! Then "safe remove" on pc, click "disable usb storage card" and everything works again!!!
Weird!

Use drop box app. Host your own files online and download them directly to your phone.

bangsters 1.5 supports usb mass storage

I'm only guessing, but it sounds to me that he's talking about apps like music and the gallery. They need to be refreshed somehow when you copy new images or audio files, and I've tried and can confirm that unmounting and then mounting does this.

Use swiftp to transfer files to your sdcard then you will be able to access them without reboot.

I am using Droid Explorer to place all the files on my phone.
Works like a charm No reboot needed, only the unmount-mount SDcard option afterwards.

Have a look at this - it may be just what you're looking for ...

(That's a market link - you'll need to open it on your phone, or search for SD Reload on the market)

Had the same problem, now I'm using an FTP server to make a connection to my phone and I'm transferring my files with Filezilla.
See ftp server in app market or on appbrain.com

How do I navigate to the USB drive?

I had it at one time but because I'm an Android newbie, I have no idea where to look.
Using Astro or ES.

It's ok, we all start somewhere right?
Load up astro hit home then up and your usb storage device is whatever is in usb_storage. Remember to give it a few secs to detect it and prepare the drive.
Your SD card (internal) is sdcard and your microsd is external_sd.
GL.
Hope this helps.

Excellent! Thanks.

Is it possible to access the micro SD card through a computer? When exploring the acer drive after plugging it in you can see all the stuff on the internal memory but can't get to the external_sdcard folder.

at the moment i dont think this is possible but give it a few days and it might be a possibility.

You can purchase (I think it was a whole $1.50) an app called WiFi File Explorer. It sets your tablet with its own IP address from whatever source you are using for WiFi. Then you access your SD Card by entering in the IP address line in your browser. The app will give you the exact address line to enter into your browser.
Its like a virtual FTS server actually. Works like a charm. If you are worried about security, you can require a password.

Accessing external sd and usb drives
It is possible to access the SD and USB drives using a file manager such as Astro or Estrongs. The drives can be found in the main directory under subdirectory /mnt.
Hope this helps. I had the same problem at first.

According to Acer, that isn't possible right now. Not that I'm inclined to believe them, but the manual is pretty thorough and I decided to go through every page and it clearly states "Transferring files from a microSD card to your PC.
Remove the card from the tablet and use a card reader or USB adapter to access the card as an external storage device."
I'm REALLY hoping they address this in an update. I thought it was a Honeycomb limitation due to the Xoom but Asus has addressed it by looping it as a folder in the internal storage so I mean, Acer and Xoom should be able to do that as well. Unless there are unforeseen problems with doing that? /shrug.

USB and a camera
Thanks for starting this thread! I'm also a newb and I have Astro and ES installed (now).
I am trying to read images from my camera (Nikon D3). When I attach the USB and turn on the camera the A500 says scanning for media. But none shows up in the photo browser (I'm sure I need a better viewer and suggestions are welcome!). When using ES or Astro and navigating to the usb_storage directory it shows as empty.
For background, the D3 holds 2 CF cards with the 2nd typically used as overflow and both are 8GB. Each card normally just has a DCIM directory with photos in one or more directories below that.
Once I connected up the A500, on one of the cards 2 additional directories were created (the one without any images currently) called .android_secure and LOST.DIR. I can't see any of these directories on the A500 or any of the images (all .jpg). I plugged into my laptop for this info.
I am trying not to have to carry my laptop anymore so any suggestions, ideas or research resources would be appreciated.

I've run into a HUGE issue. I wonder if anyone else has experienced this.
The files on my USB flash drives begins to get erased/deleted if it is still connected to the tablet when the device is activated from hibernation mode. I don't know if the file explorer apps are causing this bug. I've used Linda File Manager and Astro and 3 different USB drives to test this. I've even restored my tablet to factory settings.

Hello,
I have also problems navigating the usb drive.As mentioned above I found the dir but it shows (Directory empty).Im using a 8gb transcend flash drive.On 128mb flash drive there is no problem viewing and accesing the files.Any other have the same problem or solution?
I change the file system from NTFS to FAT32 and it works now(such a stupid user Ive become)

Hi,
Copying with a cable can sometimes lead to data corruption.
Try using a card reader.

Try unmounting and mounting your sd card within android, that´s what´s happening anyway during a reboot, due to that you can see the files the second time around.
I have heard of an app, something like dual mount or so (i´m really not sure, sorry), try using that, maybe in that case the file system updates right away and not only after the next reboot.
