Lost Folders??

So, I had a folder on my storage card named "My Documents".
Inside I had several subfolders including tomtom maps, videos, ebooks, etc...
Everything was fine, until last night, just before going to bed I was playing around with Dinasoft Memmaid program (first time using the software) and did a scan and a clean, then went to bed.
So today, I went about my life, then synced my phone with my laptop for a few hours to charge the batteries...
...and when I wanted to update my ebooks subfolder, I noticed that my entire "My Documents" folder in my SD card, was gone...
I have to confess that I didn't read much about the documentation of Memaid, but I don't think its functions is to wipe out an entire folder. I have a backup of the files so it's not an important issue.
But I just want to find out the explanation for the missing folder?
P.S. my phone was also extremely slow and unresponsive, but all went back to normal after a soft reset.

Ok...
Today the same thing happen again, but this it's more severe...
Now ALL the folders in my storage card are gone!!!
The entire 2GBs worth of data from my Sandisk 8GB HCSD card....
When I right click on properties on the SD card, it shows that the card has 2GBs of storage being used...
But when I go to file explorer there's nothing...empty...
Surely, this can't be normal...
Has anybody encountered a similar situation?????

Sounds like a Counter Fit SD Card. Where did you get this card?

No....you serious??? don't say that....
I bought it online.
www.play.com
If it's counterfeit I would be very pissed off.
I mean when it arrived it didn't look like counterfeit. It had all the right packaging.

Here;'s my thinking. People who have bought counter fit SD cards are typically getting, say, 2GB cards marked as, say, 8GB. Since the card is showing that it is one thing when it is really another you get data corruption and file start to disappear.
Since you used Memmaid it tried to "fix" the file system. Causing data corruption.
Here's what I would do. Copy all the contents of your SD card to your computer. Reformat the SD card and try again.

Problems with 16gb MicroSD card

I hope you guys can help me with the following problem.
I have bought a 16gb MicroSD card (it says it's class 4) from eBay. I copied the files from my old 8gb card to my PC and from there copied the files onto the 16gb card (I put it in an SD adapter and into a USB-stick/adapter and plugged it into a USB port on my computer).
The copying seemed to go well. But when I put the card in my HD2 it can't find the files it's supposed to find. When I put the card back in the USB stick most of the files are replaced by one with a strange code, so all the files I had copied seem to be gone.
I checked if the card was actually 16gb and it was.
Any suggestions for what might cause this problem?

Two possibilities.
1: "most of the files are replaced by one with a strange code" = You're in the Matrix, agents are coming, RUN
2: You have a dodgy card or a dodgy card adapter.
Format the card, copy files one at a time via active sync. If that doesn't work it's a dodgy card.

i don't want to open another topic... i'm about to buy a 16gb card... what should i look for?... i want something to sustain long video shots... that's why i go 16gb...
so... anyone has a recomandation as in brand or technical details....?

Hi
In my experience when you copy files to any memory stick or card and they become garbage text and can not be found by your device or pc it means it is a fake card and not the stated size. SEND IT BACK !!!
If its cheap its bound to be fake!!
There is a tool online to test memory cards and usb flash drive to prove if they are fake and can hold the amount of data stated.

Thanks. Trying that now (copying files one by one).
BTW, love your KC avatar ;-).

Hi, that's what I thought at first, but I used such a tool (I may haven't used it the right way though, should check this out again) and it said it actually is 16 gb. If it keeps giving errors it may be fake, I knew the risk when buying the card (it was cheap, but didn't buy it with Buy It Now, just by bidding). We'll seee what happens, if it keeps giving the errors, I may wait until the 32gb is released.

Ok, I've tested the card and it turns out it's defective. So I'm going to ask for a refund. New and more trustworthy 16 gb card already ordered (still a bit cheaper than the soon-to-arrive 32 gb ).

[Q] micro sd card

I have a 32g micro sd card that Ive been using in my N1. Its been basicly empty Ive had some music on it and some apps. I wanted to put some more music on it, so I transfered about 100 mp3 files over to it at once. Since I didnt have any music on it at the time I didnt really have a folder for it. So I put all the files on the root of the sd card. Now since I did that I cant get the sd card to read. My N1 says that the card has no files and if I want to use it I have to format it. When I choose to format it nothing happens. The card still reads blank sd card, I was hoping someone had some idea on what to do ?

Can you put it in a computer and see if the computer finds anything on the card?

Ya I tried to put in on my computer with an adapter and from my phone wont read.

Did you try formatting with the computer?

ya, I tried to format it and it said it was unsucessfull

1.Format with your phone Settings/Storage/Erase SD Card
2.Format using this HP USB Format Tool* (Most powerful format tool on Windows)

hello abvthegod
Where did you buy the sdcard? from Ebay? how much? It is possible that you have a fake 32GB sdcard. It happended to me aswell, I bought one in ebay, really really cheap, The sdcard seemed to work fine until I reached 1Gb, then weird things started to happen, my nexus could not recognise it, my computer crash, my camera complained.
Finally I found out that the sdcard was in reallity a 1GB card, if you try to save things in the sdcard once it goes beyond 1Gb the card did not complain, continued fine, but if I tried to take out the card and put it back any file written after the 1Gb was or 0 bytes or simple did not exists.
From linux I eventually managed to create a single partition of 1Gb (leaving the rest as a unpartitioned space) and like that I can use the card normally without issues.
You will have to try to do something like this. Usually this cheaters create this fake sdcards from 500mb or 1Gb sdcards.
You should report this user to ebay, they managed to ban the user who send me this sdcard before I even tried to complain about him ...
Good luck and I hope it is not the same problem for you!
I finally bought a 32gb expensive card from a local ebay user and that one works great in my nexus.

If it's a name brand, even if you bought it online, you can probably take it back to best buy, future shop, walmart, wherever, and just say you don't have the receipt. They just send it back to the manufacturer anyway.

/sdcard vs /sdcard-ext???

So I posted this question over and Android Forums, but no one has answered after 5 days. Hopefully I'll have better luck here.
What is the point of having an "on-board" sd card and an external card? I understand that -ext is your actual SD Card, but what is the /sdcard then and how is it different than regular "on-board storage"? What goes to either directory by default? This is the first Android phone I've had that does this, so I'm trying to familiarize myself with this.
I just bought a high quality 32GB SD card, so I'm a little disappointed that not everything is going to my SD card and instead to some onboard storage.
What are the benefits of putting things in either of these two?

I could be wrong but I think the internal memory is actually 12-16gb, but its partitioned with certain parts reserved for the operating system and apps.
I have noticed that transferring files from my computer to the internal storage is a bit faster than the external.
But then I do have a basic cheap 16gig SD card, so other cards might be faster.
I've not had any problem with the location of files, but then again I am a neat freak and I keep everything organized and know where everything is at all times

The reasoning comes from an operating system perspective. This is very much like a linux OS. Internal storage is different than ram. Android lives on seperate partitions as designed by google. Storage for the purposes of pictures, music, etc was left to be taken care of by sdcards. Since actual sdcards are more complicated than the average graduating flip phone user, manufacturers starting adding this "external" storage since it would be convenient for users like my mom. Then because geeks designed these, they still wanted to add more storage, so they designed storage you could actually get to! Hence sdcard-ext. Because many/most apps look for /sdcard as a file system, manufacturers could not skip it and just add more to the system partitions, or program installs would fail. They would either half to give a free memory card with purchase of the phone (carriers don't want to give anything away for free, and this is how it was 2+ years ago) or make storage on board that could be reachable.
In a windows point if view, think of it as all programs look for drive d: for extra storage rather than hogging c:, but since carriers didn't want to give away free d: drives, they said install it inside since it is cheaper on the board then to add a sdcard after. So, now /sdcard is like d: and /sdcard-ext would be like e:
I hope that made any kind of sense. It is honestly a useless mess, but sufficient for the unknowing or uncaring masses who just want to save more mp3's or pictures.

My issue is spotify fills up the internal "sdcard" Id ideally like to point spotify to use my external sd card as its a 32 gb card. But that wont work.
Has anyone tried to create a symlink to point a folder to an external folder?

Is there a way to dictate what goes where? For example, if I wanted my apps to go to my actual SD card (/sd-ext), could I do it?

I'm pretty sure that without some mild hacking*, there wouldn't be a universal way to do it. If it's doable at all, it will be on an application-by-application basis.
Some apps seem to just "do the right thing". For instance, as soon as I installed and formatted my sdcard, the camera and gallery applications moved my pictures from /sdcard to /sdcard_ext, and from then on, that's where pictures are stored as they're taken.
OTOH, Amazon MP3 is pretty stupid about keeping all downloaded music on /sdcard. When I bricked my phone for about a month, that's one of the things that kept me from trying for a full replacement: I couldn't pull the files out of an internal filesystem, so I'd lose all that music. If I could have had those stored on a removable SDcard, it wouldn't have been a factor.
*example of mild hacking: move application-specific directories from /sdcard to /sdcard-ext and replace /sdcard directory with a softlink to /sdcard-ext equivalent. It's hacky and crocky, but I think it would work, as long as /sdcard-ext is available and has the appropriate directory (target of link).

hopefully one of you would know this answer...
i have the droid 4 as well and i have an aftermarket stereo in my car that has a USB connection. i can plug in my phone and it wont recognize any music until i turn on USB mass storage (obviously) but the problem i'm having is that (what i think is happening) the phone is pretty much mounting the internal sd card first for some dang reason and then the external sd card second. but i can't back out of the /sdcard folder to go into /sdcard-ext where all of my music is.
is there any way to change the mounting order? <--- that's my question.
My phone is rooted and currently running the latest CM9 ROM.
Thanks

Apps will always install on the internal sdcard, no way around this.
Spotify to external SD is simple. First, erase everything and logout. During the login screen press menu and you will be able to change the default location. Login and synch and you're done.
Disabling the internal mount;
etc/vold.fstab
put an "#" before the line "dev_mount sdcard /mnt/sdcard:: 25 /devices/platform/omap/omap_hsmmc.1/mmc_host/mmc1"
This should disable mounting the internal drive. I haven't tested it though. It is possible the OS won't be able to see the internal mmc when it's not mounted.
It's also possible to swap internal with external. BUT... I've read mixed reports on an LG forum where users complained about problems with their phones. So be carefull if you want to test that out. Have to say though, apart from LG users I haven't read problems on other devices. Search for drive swap vold.fstab if you wanna try.

would it be possible to re-partition the phone's memory so that it's: system, internal, and sdcard, rather than having the sdcard and sdcard-ext seperate? I have a 16 gb micro sd card that I plan on keeping in my phone at all times that I plan to store general media on, but I'd like to keep all my apps on the internal storage. I know the process will probably cause me to lose all my data, but I've got nothing important on it. Also if this was the case would I also have to install a new version of android? Forgive me if I seem ignorant, I've only partitioned my hard disk via a bootable usb, so I'm a bit inexperienced.

[Q] download files directly to sd card?

Tried to download some files but I had to download it to phone's internal memory and then move it to sd card, since the phone doesn't allow to write to sd card.
and another problem, I bought an sdxc 64gb sd card. there's another way to transfer files from my pc to sd card in fast speed? should be like 40+ mb/s and it's transfering files around 4 mb/s, guess it's the lack of usb 3.0 port on the phone.
any faster way other than buying a usb 3.0 card reader?
airdroid and another wireless methods didn't work for me.
Thank you guys.

You're limited to what the phones USB controller allows you to communicate with it, and I suppose it used MTP anyway which is utter crap and slow.
As for downloading directly to SD card, it's impossible because Google put SD-card access limitations in it since KitKat. No worries however since Android L should re-enable those permissions again. (Apps now can only save in their own specific directory on the SD card in /sdcard1/Android/data/com.vendor.appname, so you better wait a while. If you absolutely need to move things between your SD card and internal memory to your own folders, the built-in File Commander has permissions to access your SD card fully.

You can d load files directly to your SD Card.
Settings> Xperia Connectivity > USB Connectivity> Wireless Media Transfer
You'll probably need to install the PC Companion software, and make sure that your screen time-out/stamina is off while it pairs for the first time, but then you can d/load files to your SD card.

tried that, it gets stuck and if I unplug the phone it says something about firewall and upnp, tried to disable the firewall and still the same.

No, it doesn't stick, it just takes a *very long time* to pair (once it is, it's fine) and you MUST make sure your display doesn't time out or Stamina mode kick in during the process

will give it one more try.
Thank you.
edit: it works but still slow, will consider buying a usb 3.0 card reader.

Another question, sorry for quoting you.
Tried to transfer some music, movies and tv series to the sd card. With teracopy everything seems ok.
After disconnecting the phone from pc either the music won't show or the movies, or tv series.
Befor I unplug the phone all the files appear but after I'm unplugging the phone it won't show the files on yhe phone and on the pc either.
Could it be a damaged sd card or it may cause by using exfat format? Couldn't find a way to format into fat32 format.
Any suggestions?

Are you sure the apps you are using to play/view let you into the SD Card?
I have several thousand songs and some movies on my SD Card and they are viewable from my apps.
The best way to format your SD Card would be from the phone itself if you want to guarantee the phone recognising the contents. I believe you use Settings > Storage > Erase SD card (My understanding is that it will format the SDCard too) write speed will be determined by the SD Card too, is it a high speed card? I also find that if you try and write multiple files, it slows down everything hugely, so I tend to do files singly (in the case of movies) and in smallish batches if music.
If you're using wi-fi, the speed of the network/distance from the router will play a part too

The item has been removed from ebay so here is some details but not the model number
64GB SanDisk Extreme Micro SDXC Memory Card Class 10 - 45MB/s UHS-I U1
Formatting it through the phone makes it exfat.
And yes I'm sure it's the external sd card.
But how is it possible that the sd card is full, I unplug it and plug it again and the folders are there but they are empty, plus no matter what is the size of the files that I transfer I have like 4-6 free gb's, there should be like 40 free gb's after the size of the files that I transferred.

You should consider that perhaps you got a cheap copy card and it's not working at the speed it should be, there are card speed apps on Android Market that should be able to tell you how fast its working. https://play.google.com/store/apps/details?id=com.a1dev.sdbench&hl=en

Yes, it's a fake for sure.
About 2-3 mb/s reand and write.
Since the item removed from ebay I can't open a dispute. Hope PayPal will refund me.

If nothing else, at least we've worked out the problem

Not sure if this was already solved.
If you go on Camera, Settings, "Data Storage" change to SD Card.
Erasing the SD card from the phone seems to work more efficiently to provide you the confidence of starting from scratch.
Now everytime I take pictures or Videos, it is transferred straight to my SD Card.
Hope this helps for some that is still having some difficulties with the topic.
