[Q] Media files randomly disappear when connected as usb disk mode.

I havent yet found any solutions to this problem and decided to ask here.
This happens at only Sense based roms!
When I connect my phone as usb disk drive to pc and than back %90 of the time my media files randomly disappear. Many of my music files gone missing and my selected rimgtone / alarm etc mp3 also returns to defaults. Videos photos randonly hidden from system as well.
The files are there but android os cant access them. Only way is using an app like SDRescan this solves the problem until I connect the phone again to transfer files...
Please I have tried everything from formatting the sdcard with fat32 again to searching for .nomedia hidden files etc etc. No solution worked yet.
Again only Sense roms do this. I used MIUI and CM7 too they didnt have this behaviour I never loose any files like this.
Extra info: My phone went to service and mainboard changed and the same thing is happeneing so I have no reason to belive it is about the phone.
Only Suspect: SDCard. (The default one that comes with the phone) But it is not really a strong suspect. Cause it works in other roms.
Anyone has any solution? This is driving me crazy and I want to use my phone with Andoroid revolution HD rom.
Any help is appreciated.

123 hits and noone has any idea?

Could be something related to mediaserver...Nothing comes in mind as I'm playing paintball right now. Does this happen on all sense ROM's, (2.x - 3.x) or ARHD in particular?

Oh god an answer finally!
Ok this is my history with Desire Z:
bought phone:
Stock Froyo -problem
upgrade:
Stock Gingerbread - problem
rooted:
CM7 : no problem
MIUI (bulletproof) : no problem
lets try sense again after a long time!:
Revolution HD Rom: Problem again!!!
BTW I am not a noob. I have prepared an s-off/root and custom rom guide for the most popular forum in my country and helped a lot of people to root their desire z's.
Running ARevoHD rom with swap and supercharge with out any other problems at the moment.
But this stupid bug is driving me crazy. I gotto run SDrescan app after every time I use my sdcard as a disk.

Eh, sorry for not replying earlier, just came back.
Now, the behaviour you explain is odd. Have you tried logcat and see if there's any relevant output? I'd look for "Mediaserver" first. By the way, have you tried plugging the phone to another computer? I'd try that too.

The behaviour I told you isnt very uncommon. Many people have this problem. HTC answer it by saying "format your sdcard" some people says it fixed theirs. But my problem still goes on. Also I dont know where to and how to look with logcat. This happens when I choose DISK mode when connected with usb. And than when you go back to normal mode mp3's are gone until you rescan.

I cant believe I am the only one having these issues here.

Shameless bump

What brand card do you have? And remember, XDA is not your Tech Support site.

Yeah sometimes I forget this is a developer "only" forum and the residents are usually elite and unforgiving people and not to be disturbed by petty questions of "15 year old boys".
Excuse me for my question and thank you for your help.
I wont be disturbing the forum again.
BTW before the flames:
I respect all the developers here for whom I am very grateful of and I get triple the fun from my Desire Z by the works of them. Thank you.

People come in, they read it, but have no idea how to fix your problem, so they don't reply.
There could be a problem with the rom, where it doesn't mount the card properly. Also what OS are you running, and how do you unplug the phone? Many people ignore the saftey removal warning for flash drives an other devices, but sometimes it could be the culprit. Next time make sure you go through the process to safely remove hardware and xee if it happens again (On Windows, right click the little icon in the bottom right to safely remove, and on mac, drag the 'drive' to the trash bin (which changes to an eject button)

Nothing is changed how I remove my phone from USB. I tried everything and it seems unrelated how I unplug.
Because this happens when I change my phone from disk mode to charge mode even.
ALWAYS the same MP3's are lost I am sure because I change my ringtone to same mp3 everytime and when this happens that ringtone disappears from music player and I cant choose it from ringtone setup screen. So until I rescan my sdcard with an app I cant seem to see those mp3's. There is nothing wrong with MP3's too.
I am not sure if the problem is my SDcard or the general Sense based roms. I am truely lost in this case.
It never happens if I dont connect it to usb and change to disk mode.
My theory :
Somehow the mediaserver who archives the media files forgets half of my files when lost connecttion to sdcard. I dont know why or how.

i used to have the same problem, but it disappeared by it self i don't know how, try formatting it

Oh as I said in my original message I formatted my SD card with fat 32 system and this didnt work at all. I will try again but it is frustrating to backup gigabytes of data froma slow card meh
It is good that I am not the only one I hope to find some reasonable solution to this.

I can't see my files or pictures when connected to PC, help!!!

OK this is driving me crazy, when I connect my phone to my PC (Win 7) and go to my phone files they all look empty, I click on DCIM and choose camera all my pictures are there but I can't see them they don't popup automatically like they use to, the only way I can browse through my pictures is by opening them up individually, I tried the same thing with my old Galaxy S Vibrant and it works just fine I can see all my files and the contents without me opening them up, so I know there is nothing wrong with the computer. I tried different data cables original and others again with no luck, does anyone have any idea what is wrong with my phone, please help.

Can you post a screen shot so that we have a better idea of what you are talking about?

I have the same issue extremely intermittently. The only resolution I have discovered so far is to disconnect and reconnect the phone to the PC.

I attached screenshots check it out

I just connected my S3 to see if mine did the same thing, and it does. I think that the problem is that the phone connects to the computer using MTP and not mass storage. Here's a link with some one else that had the same problem.

Thanks for the reply, I'm kinda glad to know it's not just me that can't see any thumbnails, can someone else confirm that these devices don't load any thumbnails...

Damn it man, I can verify I have the same damn problem. Followed the link posted and nothing in there was helpful. If ANYONE has a link or answer please post. It would be most appreciated. Meanwhile i'm going to start researching the issue, if I find a solution I will post.

I can't believe a flagship devise like this can be this low tech, I have over 500 pictures in the camera folder how can I see the pictures I took recently on my PC if thumbnails won't load up, I hope the next update will address this problem and fix it.

Well I found some information in the link below. However every time you reboot you have go thru the process again and it is only for the external sd card. You are right this is extremely sad for FLAGSHIP DEVICE, I guess I am lucky I dont have that many pictures and dont take that many pictures that I can manage them thru the device.

The solution I found
This might not be the solution you are looking for, but it fixed it for me!
Basically, if your screen is locked when you connect your handset to your computer it will not read the files. Simply unlock your screen before connecting and they should come up...
If you think about it this is actually a pretty good security feature, but pretty confusing if you are not aware of it.
Hope this helps, I set up an account just to answer this so I hope it was worth the effort! haha. :victory:

Wrong forum. Find the forum for your device and ask there. This is for the GS3 only.

[Q] [Help!] Broken Screen, abd device unauthorised.. ripping hair out!

Hi Guys,
Basically recovering from a broken Ankle, so decided I would fall on it and destory my phone in the process. At the moment I do not have enough money to buy a new screen, if I did this wouldn't be an issue. I need urgently to get access to remotely screen cast the device OR get my text messages backed up as I need some of the numbers ASAP!
The phone is rooted I believe it has the OMEGA rom installed. I cant see anything apart from a couple of lines on the screen and the digitizer isnt properly working so I cant unlock it on lucky guesses!
I have tried to get screen cast to work, got up to the point of restarting the adb as it kept saying offline, now it says unauthorised. So i am pooped with ideas!?! I dont know what my options are now, I can still get into download mode, not sure about the recovery menu as I cant see anything.
Does anyone at all have any ideas? I am ripping my hair out haha! I need this information because the person I am trying to contact owes me enough money to get the screen fixed however I cant get his number, not even through my gmail because for some reason non of my contacts are now synced?!
I may have a possible backup from mybackup or something if it is possible to restore that to the computer? I think some of my contacts and text messages are stored with my samsung account however I cant download that from the website..
Samsung Kies is no good either, as cant connect to that.
I think that is as much info as I can post, if you need anymore to help please let me know. (I will be back online in a few hours, need to calm down and have something to eat!)
Thanks in advance but I understand if nothing can be done, unfortunately due to lack of work and the debt left from the ex, I now have a problem. And I cant claim on insurance as it is rooted.

The reason ADB is saying unauthorized is that there is a warning pop-up on the screen when a computer connects. If you reboot into recovery you might be able to circumvent this.

do you know anyone with an HDMI adapter? you could get a display that way and find a method of your choosing to backup anything you need.
Edit: If you just need numbers try checking your online account with your service provider, you may be able to get some of the numbers that way through recent calls.

Sorry about the late replies guys, had to go away for a few days look after fam member.
I know this, but I cannot authorize it because the screen is broken. What ways do you know of recovering through the Recovery? Download mode can get into, recovery I cant do much from? Without seeing it.

Hmm, A HDMI adapter would that require any settings changed on the phone to enable it, or is that just a plug and play device? Online accounts currently don't have anything stored because sync messed up.
Mods: Can I get this moved to the normal GT-I9505 section Q&A as didn't realise this was T-Mobile and it's unlocked

Recovery should work to get adb working. Then you can pull the mmssms.db file along with it's counterparts and retrieve all your messages that way.

[Q] Retrieving text messages from Samsung Galaxy s 3 phone with screen not working

Hi
I posted this message a while back but I couldn't understand how to try what was suggested, or maybe they weren't the solution to the problem. I further asked the advisors but didn't get any replies, so I thought I would post again in a hopefully more relevant area of this site. This is a genuine request and would appreciate the help.
I have a broken Galaxy 3 phone where the screen suddenly stopped functioning with a total blackout so I can't use the phone at all. There is no problem getting the phone fixed within a couple of days but the problem is I want to save all my messages, contacts and other data, to my pc, especially one conversation text message thread that has gone on for about a year. I want the information to be able to be viewed independently on my computer like I read emails etc. and then I can store it on a portable hard drive by copy and paste. Samsung kies doesn't seem to allow for this. I can back up the phone apparently but the info can only be read by another similar phone so it is restricting how you see your own information. I want the information on my computer without the need of another similar phone because what if I decide to buy a totally different phone that has software that's not compatible. The shop representing Samsung who will fix the phone said that everything gets wiped and they won't even have Kies on their computers because they think its unstable software. Ideally it would be great if there was some kind of software for my computer that enabled it to read all the info on the phone as if the phone was a flash drive connected by USB and then I could simply copy and paste across from phone to computer. The phone is recognised by the computer through the USB but obviously it can't read inside the folders on the phone which just show as empty. Anybody know of anything to get the results I want? Thanks.

Stuck scanning files phone works but pics gone HELP anything

I woke up to my phone on and it was back to factory settings and all my photos, contacts, kids, parents vids gone. I'm sick and the data recovery people want $1000.00 to possibly get them back. I have read until my eyes bled. "try to root it... DE-soder the chip. Sprint even told me that my modem is not communicating with the "hard drive". I don't know if these files are still there as when I plug it in the only file it shows is a single ring tone. I will try anything and I'm even willing to pay someone to attempt to recover the info for me. I just don't know where to start and there seem to be people that know so much about this stuff that hopefully someone can point me in the right direction. You guys Rock. My Mother and I thank you for any info that you may be able to provide to help get back these messages and videos of my deceased father. lg ls970. I can talk on it and even check my email but it still says scanning files and if I attempt to download anything it says no room. Thanks again for any direction
All The Best
PS. The phone is bone stock.
