why cant i copy large files to my miniSD card???

so i downloaded Pocket Quake for my wizard and am copying my pak0.pak file to my SD card. its a 175mb file and i have 1.4 gb free on my card. i tried exploring the device via Activesync and drag n drop the file, but it copes a portion of the file and shows that the device is unplugged!!!!!
i tried putting the miniSD into the SD card adapter and put it in my SD card slot on my laptop and i cant even access it because it keeps telling me that my card is not formatted. i have formatted this card before, but i guess it wont let me access it within windows.
how the heck am i going to get this 175 mb file on my card? this is so frustrating! thanks.

Its a bug with activesync - you have to use a card reader to transfer large files or wm5storage (use storage card as usb storage device). Activesync sucks!
wm5storage download link http://forum.xda-developers.com/download.php?id=11800

I noticed when I move any file to the minSD through ActiveSync, it takes FOREVER. A song takes at least one minute to transfer. I dont have a card reader so I havent tried that yet.

im afraid to eject my card, cuz everytime i do, it messes up on me...

i just installed this on phone.. how do i use it?

thx for the program, meschle.
it took me a while to figure it out too, but u go to START, ACCESSORIES, then run the program, ACTIVATE and if you have your wizard plugged into your usb then it should detect as a removable drive.
it worked for a while at first, but now my data on my storage card seems to be corrupted =\ gotta figure this out now.

It might be corrupt becuase u unplug da cable to fast. 100 mb file is big for ur device's processor, wait awhile before you unplug the cable

G1 can't copy large file from computer to G1's SD card via USB

hi
My G1 can't copy large file from computer to G1's SD card via USB. Everytime i tried to copy a large file to SD card via, the G1 will turn off the USB storage. Would you like to let me know how to fix it? Thank you very much.

Define large.
And secondly, what happens if you try to even access the files on your SD through windows? Do you get the same behavior?

Filesystem is formatted fat16 OR bad USB wire OR you use windoze.

I am having a similar problem. I have a Rogers G1 and bought a 16GB Lexar card from Walmart for $55 CAD(seemed like too good a deal and it was). Took it back after trying to reseat the card several times and the issue still persisting. The 2nd card is still having the same problem.
I first noticed it when trying to copy my 8 gb MP3 collection... after about 5-10 mins of transfering the SD card becomes unmounted.
I suspect that it will work fine if I mount the card in an adapter and put it in my laptop, but will confirm.
Might try to fatten up the micro sd card a bit where the connectors are, and see if it makes better contact with the phone...if transfers work from the laptop.

'Large' means the file size is more than 100MB. I can copy the large file to SD via USB adapter successfully. And G1 itself can access large file successfully. Now i have not test it in Linux environment.

thl16888, What kind of memory are you using? Who did you get your phone through? Little shy with your details..
I am able to copy files from widows directly to the card as well...just not so well on the phone.

My SD card is Scandisk 4G. I can copy large files into sd card via USB reader. it is not so well via G1's USB.

There is a 4 gig file size limit on Fat32 format. So anything larger will not work.

I have the same problem in Windows. However in Linux it works perfectly so I know the phone cable and SD card are fine. That only leaves one problem, Windows! I think the Windows USB driver is not very stable.

My g1 had the same problem..so what I did was mounted it in terminal..the phone can't scan it so it can't close it...so heres the url enter this in the terminal emulator or console click here

i have a similar problem to, help plx
I have similar problem to, but itz with any file, until the smallest note 1kb.
I try to copy a file, like a music, ok, its there, but after when I remove safely the usb, and unmount on the g1, I look for the file and its not there. I tested with every type off archives, and with a 200mb file, the sd don't keep the file. Help plx , maybe its a config wrong.
Ahh, and I can't download files on g1 by browser, it says that I haven't space, but I have 3GB on sd and 20mb on internal.
Before I haven't this 2 problems. Someone know what are the problem?
Sorry by the bad english, I'm portuguese =P

I have the same problem, i can't copy big files to the G1. When i put the sdcard in a card reader, windows detects nothing.

Download MountUSB App from the Market on your G1, and try again....that worked for me.

I'm having similar problem just copying a 646KB file for Cookie Monster's app. It constantly disconnects from my pc.

microSD disappearance.. SOLVED!

People have been replacing their microSD cards not knowing that the problem is actually in the files and folders..
Ok here it is!
When i scroll through the hTC Sense tabs to music or photos, the applications try to load the thumbs from the Phone/microSD, that's when it suddenly freezes then the microSD vanishes..
I inserted the microSD into my PC and browsed the drive in "Thumbnail view" and guess what happened, it froze.. I figured since the idea was the same in hTC Sense when it tries to load any thumbs..
So i went to the microSD drive again and chose "detailed view" then went into each folder and changed to "thumbnail view" until i found two folders that kept freezing; "Program Files" and "My Music"..
In Program files the only folder that couldn't be deleted definitely had files that were behind the issue.. There was a music album too that froze, i deleted that too...
I backed up my files and formatted the microSD, i had to, because the folders behind the microSD disappearance cannot be deleted even with an "Unlocker"..
So far i'm playing around with my Leo and nothing is happening..
So by viewing the folders on the PC using Thumbnail view, you'll be able to identify the file or folder behind this annoying issue..

I had the same issue
I have (had) Sandisk microSD 16GB card. It was last week that it happened to me. Only backup of good files and re-formatting the card helped.
Today, I was copying 700MB file and suddenly it told me - cant write on a disk. I disconnected cable from the PC, rebooted Leo and SD card was no more present.
I put it into a card reader, tried to format it, but nothing is working. SD card is probably faulty.
So be aware, that that problem might be a first sign before your SD will break.

I think the fault is from some files somewhere in the microSD.. After going through the method i mentioned earlier, up until now my card is fine..

yup right, but be aware. I dont think that normal SD card should perform like that. I am using stock 2GB SD now, and it is ok!

My 16GB microSD is Sandisk and its 100% compatible with this device.. The Leo is doing something when loading the files creating some system files i suppose..

guess what? windows could not load sandisk microSD 16GB and I was already preparing to return it to e-shop, but I tried live cd of ubuntu 9.10.
It can read the card, it formatted it and it is working again! :-D

That's great, so you didn't have to replace it?
But strange, i've always been using the 16GB with my HD and now HD2.. The issue just occurred a week ago..
A day has passed and everything seems fine..
I hope it stays that way..

ok
I got exactly the same problem with my 16G Sandiskin and HD
and found that the problem was a damaged file in my SD
connect your SD to your computer throw card reader, using total commander or whatever, begin coping all SD files and directory to your hard disk, until get a message can't copy "file name", this will be the damage file, unmount the SD and mount it again and delete this file and your SD will be ok
ps: may be you have more than one damage file, try the this method until you can copy all SD files to your hard drive

When you have a write or read problem with a particular file, it usually points to more than just a corrupt file. In my experience with 4 16GB Sandisk microSD, it is the beginning of a failing card. The safest bet is to copy out the good files, reformat in your HD2 and copy the files back. But if it happens too often, it may be time to invest in a new card as your data is of primary concern.
The strange thing is that this usually occurs with the bigger cards, 8GB and 16GB. I never had this issue in the past with smaller cards.
I back up my card weekly or when I have updated large number of files just to be sure I have a valid set in my PC in case the card fails.

I know what you are talking about. Low format may help. I had the same issue with 2GB SD card 3 years ago (had to recover SD card to save few photos) and also on my DLSR with 4GB CF Card (linux helped to read the card). I don´t think it can be damaged so quickly as normal PC HDD, but when it happens often (damaged files on card), it may be a sign of something wrong with the card.

Unfortunately it happened again.. After a month of having everything under control i got the same problem.. The great news is I'm using windows 7 on my PC and when i plug my microSD card via usb reader, i get a choice of scanning and fixing the removable disk...
Now i'm happy without those annoying corrupted files..

SD card Read/Write Problem

I have two 16gb micro SD's and I've found a similar situation in both cards.
When I'm in usb data mode (either in Android or WM) files will NOT copy onto the SD card. It will show the file icon but there is no data there.
eg. I copy a song onto the memory card, I see the song name + icon on the card. Disconnect USB mode, and go to play the song... it's not there. The phone can't read it.
At the moment I've resorted to sticking my memory card into my N95 and copying data that way... so sad lol.
Any Suggestions/Ideas?

It could be that the data is not actually being written before you dismount. Make sure to properly stop the USB device. Its happend to me before. Sorry couldn't be of more help.

I had some similar problems, I ended up using micro sd in laptop to copy some files over. Or, I rebooted phone after sync and they were there.

Help! How to put mp3 into HD2 android ?

Whenever I want to put some audio file like mp3 into my memory card and return back to my device, i can't find any of it in the memory card.
I tried unmounted the SD Card and mount back also cannot solve it.
It just won't show up in explorer and music application. So i plug it back to the PC and found that all the songs are gone from the memory card
Anyone mind to help? Thanks.

Hey,
try this procedure:
1. go into harddrive mode to move your files on your device
2. When done with transfer, go to your win (pc) task bar and unmount android device safely (not unplug the cable, only chose the option)
3. On your device change mode from harddrive to load only. Wait a few seconds until sd card is mounted again. then unplug cable and you should be ready...
this at least helped me...

I tried your method but no success.....
I am sure I have removed the device safely in PC, change mode to charge only and wait until SD card finishes remount

Problem solved using Droid Explorer to transfer files and then let SD card prepare itself

What I have always done is put all the Music into "Music" folder on the SD card and the albums in folders within the Music folder. I know it sounds simple but if you are putting audio directly on the SD card, then it might dismiss the audio files as not needed for Android.
Also make sure your SD card has had a full format before putting the Music onto your card. Make sure to backup your data first of course. Then once formatted and files have been transferred to your SD card, go to computer and right click and eject to make sure it is safe to remove. This is what I always do and I have never had any problems.

why are you making this so complicated? if you're having issues why not boot into windows, sync your phone with the pc, transfer all the mp3's you want into a music folder in your sd card, boot back into android and they'll be there.
