[Q] Reboot needed before stuff on SD card appears?

This sounds weird - but whenever I transfer information to the SD Card it doesn't become visible until I reboot the N1. Any directory changes, new files / deleted files don't become visible until a I reboot, even though they are visible from the PC. Anyone got any ideas why?
I use the SD-Share/SD-Split app from the marketplace to allow me to use Co-Pilot Live at the same time as reading the SD card as a mounted USB device in the car.. (the file changes aren't visible from ASTRO, Bluetooth file manager or eFile file managers)
Am I doing anything wrong? Is this normal behaviour? (I use the latest enom ROM)

Your SD-share app is causing this effect, I believe.

Files on ext. SD Card deleted by Media Scanner

Hi folks,
the Android Media Scanner is deleting files stored on my ext. SDCard.
First I thought the card is broken but then I found this:

Is anyone else having this issue and/or got a solution for it?
Thanks!
Edit: I am on CM7 n82 currenty

Probably own fault. Might be cause by mounting ExternalSD wrong way.

Gonzales,
I updated from Android 2.3.4 to 2.3.6 this weekend, and the problem started. I came across both threads at the Android Developers forum, and found no solution.
You do mention above that it was "probably your own fault... see updated thread". Well, I did read the updated threads, and found no solution.
You hint that it has to do with the way the card is mounted/unmounted. And this weekend I did in fact mount/unmount the card various times, connecting it to the PC.
But what exactly did you do? Did you find a solution?
Thanks,

[SOLVED] Media Scanner Deleting Files from SD Card
OK, I believe I found the solution. Apparently the problem can be caused by the SD card being mounted and/or unmounted properly. In my case, I was connecting/disconnecting to/from the desktop PC, having the SD card as Mass Storage. At one point, Android wasn't detecting it anymore so I removed and inserted it a few times.
I did what I describe on the same thread at Android Developers: http://code.google.com/p/android/issues/detail?id=3692#c117
Here's what I wrote there:
So I did the following, and it seemed to solve.
1. Connected phone via USB to desktop PC, and dismounted card from phone, allowing data transfer to PC (via Mass Storage Device)
2. In Windows, as a test I created various folders with subfolders, with image files in them. On some I placed a .nomedia file in root and sub-folder, other only in root, others I renamed the sub-folder to start with a ".", etc. (NOTICE: I copied existing .nomedia files from other folders, as Windows doesn't allow files/folders starting with "." to be created)
3. In Windows, I ejected the USB drive politely (i.e.: I didn't just pull the cable out)
4. On phone, opened Settings/Applications/All and found Media Storage
5. Deleted data from Media Storage
6. On phone, I disabled the external access (file storage)
7. Waited patiently until SD card was detected and mounted (previously, I tried forcing that to happen by opening applications that would query the SD card)
The phone performed the Media Scan a couple of times, and ALL MEDIA FILES REMAINED THERE, where they would originally have been deleted from.
In all test folders I created from within Windows, no files were deleted. And in folders that originally had media files (which I didn't touch through Windows), the files no longer were deleted.
Anyway, this seems to have fixed it for me.
My system:
Samsung Galaxy Ace, Android 2.3.6, rooted.
An extra hint: if you feel you card access is slow, get an app like SD Booster and increase the cache size. On my device, it was as low as < 100Kb but increasing it to 1024Kb made a huge difference.
And if you don't want the media scanner to run on boot (increase boot speed), use Rescan Media Root.
Both need root access, by the way.

And I've had no problems at all ever since, and even mounted/unmounted a couple of times.

Storage issue (Phantom partition?)

So my One has been well above 20gigs of used space for some time, With an average of about 3 gigs of free space at any given time. I've checked my sdcard folder and it is about 5gb of space total (with downloads and everything else). There have been occasions where I plug the phone into USB and go to a folder quick and the files are ones I've never seen before (example in downloads folder the files are different then my actual downloads folder). I also have a directory 0, emulated, and legacy inside of Storage. These are exact synced copies of sdcard. Each taking up the same space (so 4x the actual amount of used space) and if I delete a file/folder for anyone of these directories it removes it from all including the sdcard.
Has anyone experienced this? is there a way to fix this without wiping the entire phone clean?

Do you go between AOSP/Sense roms? I don't see it anymore but it used to happen back when AOSP first starting coming out for the phone. It had to do with the multiuser support. It would leave all your Sense files but it would move the AOSP folder so you couldn't access them. Flashing a sense rom would let you access those files. I believe you can also access them by using a root explorer (es file also has a root option) and going up to /data/media you should be able to see those files and /data/media/0 should be the AOSP files.

browser which can download to internal memory

Since actually i don't have a uSD card in my Nook, i would like to dowload small files directly into my internal memory.
By now i've tried:
- Opera Classic 12.10 (gives an error due to missing SD card, cannot change download location)
- Dolphin 10.3.0 (can change the download location in the settings, but still gives an error due to missing SD card )
- stock Android browser (seems to download, but i could not find the files anywhere in the fileststem )

Unfortunately I doubt that it's possible because of the way that B&N has the eMMC partitioned, but to be truthful I have not personally looked into it very far.

I can tell you for a fact that you're not going to find an external browser that can download to the internal memory.
However, I think that the stock web browser downloads files to /data/media/B&N Downloads/Extras by default; the best way to check this would be to open the browser settings menu and see where there's a "Where to download files" setting. (I can't do this, as I uninstalled the stock browser a while ago).
If you'll provide me with Browser.apk from your /system/app, I'd be glad to do some testing for you; other than that, just buy a 2gb microSD card, they're diry cheap and well worth it.

Device creating weird files on SD Card

Hello!
For a few days now I've noticed that my device has been creating some weird files on my SD card. I have tried formatting the SD a few times but it still happens. If I do not delete these files more and more keep being created until there are hundreds of them in my SD. They seem to not take up any space at all, but it bothers me having to browse for files in the card. I have attached a screenshot from the root of my SD card with the suspicious files highlighted. If they are completely normal for an android device, I would like to know if there is a way to stop them, hide them or maybe have them appear inside a separate folder so I can keep my card organized.
Also, it may or may not be related, but whenever I'm listening to music (whether it'd be Play Music or another app) sometimes the phone stops playing it, as if I closed the app. I had Clean Master installed and it happened frequently until I figured out it was the source of the problem and uninstalled. It worked fine for a while but it started again. I believe it could be related, since I keep all of my music on the SD card.
Thank you in advance for any assistance provided!

Do you see these files only when phone is plugged to PC via USB or can you see them with ES-Explorer or similar Filemanger on the phone also?
I have a few of these files but they are only present when I check the SDcard on a Windows- PC, in ES or Rootexplorer they aren´t visible.So my opinion is that these files are created temporary for connecting.

The files also appear with file managing apps on the device as well. As you can see, the files have "reproduced" since I started this thread.

I also have the same. Just deleted 400 0byte files on my motog 2ndgen sd card (kitkat 4.4.4). I see them with es and when connected to PC.
