Ok, I was trying to place some .zip files on my internal memory root for storage purposes. I used root explorer, changed to r/w created a folder (/storage) and put the files there. When I restarted my phone they were gone. What happened? Is there a reason this shouldn't work.

The internal storage is checked during every startup for integrity just in case something is wrong from last shutdown... The best bet is to put your files to /data folder if you must put stuff in the internal storage (not recommended)..
Don't create your own folders, it will be removed by the integrity checking...
SDCard is still the best location for putting ALL user data
I suspected as much but wasn't too sure, thanks faux

Thank you I also had wondered this, totally abandoning the idea now, WOOT WOOT West L.A.
!IMPORTANT! - CHECK FOR POSSIBLE DATA CORRUPTION​
Quick Steps to check for possible data corruption:
1. Navigate to LOST.DIR Folder in Internal/External SD card using any file explorer (My Files, ES File Explorer, Astro Explorer, etc.)
2. If this folder is empty then you have nothing to worry about - no data corruption! Otherwise, delete ALL of these files (Labelled with various numbers)
3. Reboot device/Restart media scan for internal/external SD card
4. If files reappear straight after reboot/rescan, then there's a possibility that there are damaged files located on the phone or your SD card is damaged/error with file system used.
[If LOST.DIR folder remains empty after reboot/rescan then your SD card/DATA is safe]
Locating damaged files:
- Open the file using any file explorer (My Files, ES File Explorer, Astro Explorer, etc.) and choose to open as "Text" [Alternatively, you can connect/mount it to your PC and open the files with notepad]
- Text should indicate location of possible corrupted file, navigate yourself to this file
- Make backup of file on PC
- Reboot device/Restart media scan for internal/external SD card
- Check LOST.DIR again if any files are recreated, if files are again recreated, then move to next section.
SD card is damaged/error with file system used:
- If you are using a lagfix (especially those with EXT2 as LOOPS), then disable them and/or return to the RFS file system.
- Reboot device/Restart media scan for internal/external SD card
- Check LOST.DIR again if any files are recreated, if files are again recreated, then I would suggest you reflash your ROM and repartition/format
- If LOST.DIR files continue to reappear instantly after a reboot/rescan, then I would suggest you flash back to stock and contact your device maker for warranty claims.
Possible Causes for creation of files in LOST.DIR:
- Improperly turning off device, such as pulling out battery when device is still on
- Interrupted media scan
- Files copied for PC were corrupted initially
- Damaged SD Card
- Fake SD card
- Disconnecting your device when mounted as mass storage device to your PC (without first properly unmounting it)

Having lots of files in your LOST.DIR does not necessarily mean that you have any data corruption - As noted by some users, it is safe to have these files, but I believe if these files continuous reappear in LOST.DIR, right after a reboot, then you have might have a problem
Delete the files, reboot, and navigate back into LOST.DIR folder and if files are recreated then you possibly have data corruption, if LOST.DIR folder remains empty then you do not have to worry about data corruption
----
EXTRA INFO (Edited by me - thanks to rschenck for clarification/original post):
The LOST.DIR is where the system stores orphaned, damaged or corrupted files it finds during the file system check as it boots up. It would be expected that most all of you will have at least a few orphaned files in there. They are perfectly safe to delete, however, if after rebooting the system, MORE files are created in LOST.DIR then these aren't orphans, they are corrupted files and could signal a problem.
Hopefully when you delete them, they will not be replaced at reboot and you will gain some peace of mind that their is no evident DATA/SDcard Corruption/failure
This is a very important housekeeping/maintenance procedure to extend the lives of our phone, especially for those using EXT2 or loops.
Best of luck,
Peter
My lost.dir folder is empty.
I didn't use a lagfix for quite some time though.
I only recently used and ext4 lagfix which has been enabled for about a month or so.

Then your ext4 file system is good to go I'm using ext2 and my lost.dir fodler is empty too
Wrong section and useless post (as it was in speedmode section) as its too panicky and unnecessary (it is perfectly safe to have these files, and even if we have we don't need to remove lagfix, just switch on the brain).

That's good to hear I hope my post is clear enough .... Again, having lots of files in LOST.DIR does not necessarily mean that your internal/external SD card is damaged, it just means that there has been some form of data corruption and by deleting and reboot, you can confirm that your SD is not damage but instead there has been some data that was corrupted.
I think those files can also be the result of disconnecting your phone when mounted as mass storage device to your pc (without first properly unmounting it)

Having files in the LOST.DIR folder does not mean that your SD card is damaged/data corruption - but if they reappear after reboot/rescan then there's a possibility of it.
Hmm...
I have some files in LOST.DIR folder, some in my internal and many in my external. I have deleted those files in both SD then reboot. My external SD's LOST.DIR remain empty after reboot, but in my internal SD there are 2 files reappear.
I am using ext 4 + ext 2 loops...
Thank you very much for sharing this, I will try to figure it out...
I get 2-3 files in LOST.dir on my internal SD. I have only tried this twice so far. I'm using EXT4. So what now?
Sent from my GT-I9000M using XDA App
No lagfix Eclair lost Dir has a few files in it .
Moved on lagfixed rooted customised etc etc .Six months a few files in Lost Dir .
Yesterday got about a dozen files in the directory . Why well simple all Titanium backup files and i had a problem with a restore on that app .
Conclusion and from OP post any file that gets damaged is moved to this folder .
A folder to keep an eye on just in case as a warning of possible corruption or bigger problems .

Remove your loops then check LOST.DIR again. (and/or refer to the Locating damaged files section)

Again, if files do not reappear right after reboot/rescan, then you do not have to worry.

Exactly
When using the Android File Transfer app on my Mac, I saw this folder named "storage" which doesn't have much in it and so I decided to delete it, which wasn't a good choice as I found out everything in the internal storage was wiped.
Is there any chance of getting the lost files back?
Now whenever I connect my phone to Mac Android file transfer app doesn't show up the internal storage folder anymore.
Panicking.
Help!!! Anyone?
Nexus 4 on PA 3.1
It's gone now. You'll need to restore the factory image to get the internal data in order and then re-root/setup the phone
hi folks,
can anyone explain to me how the the available internal memory is reported in settings->storage on the i9505? mine seems pretty nonsensical.
its reported as follows:
total space 9.25gb
applications 1.74gb
pictures videos 12.54mb
audio 240kb
downloads 20mb
miscellaneous 435mb
available 2.32gb
furthermore, es file explorer is reporting that 6.92gb out of 9.25gb available memory is used, which matches the 2.32gb available reported in settings->storage.
so where is the remaining 4.7gb??!?
i used the sd card analyser in es file explorer to see what's going on and where the data is but adding up all the data there does not account for the missing 4.7gb??
any clues?

Hi,
Have you perhaps made a nandroid backup which saved to your internal memory?
hi malybru. no - i've done nandroid to extSdCard. if i had mistakenly done it to internal, the data would show up in the clockworkmod folder anyway, which it doesn't.
i have flashed to official BTU roms from odin, without wipe, and rooted afterwards each time. could this have anything to do with it?
when i attach the phone to my windows laptop and examine the internal memory in windows explorer, under properties the phone memory is saying 6.92gb used out of 9.25, yet when i select all the files and go to properties, it only adds up to 500-500mb?!?

Hi,
I use a great app from the market,called "FX File Explorer"
It has a "View " button at the bottom of the page which will show you a breakdown of the data on your phone.
Click it when you are in your Main Storage.
It might help to locate some stuff that should not be there.
If not,it's still a great app to have.
yes es file explorer has the same thing. there's no sign anywhere of the missing 4.7gb data! all the files add up to about 600mb.
i still have no clue about this. how about if i backup all the files, reformat internal storage in recovery, copy files back?
i had this problem before.. then i checked data/media.. there should only be 3 folders there which are: 0, legacy and obb.. move every other folder to 0.. hope this helps..

you sir are a genius. that was it. there was a clockworkmod folder in data/media with a nandroid backup in it. deleted it and missing storage recovered! thanks!
