The weirdest thing happened to me today

The weirdest thing happened to me today and I was wondering if anyone can help me identify the culprit.
I was listening to some music when all of a sudden the player (Nitrogen) freezed.
I opened the player again and the songs wouldnt play,
so I looked in the library only to find that there was one song left in my /Storage Device/Music folder.
I have roughly 1.5 GB of music on my 2 GB sd-card.
When I got home I put the sd-card in my cardreader and it says that there's 100 MB of free space left
but when I select all files on the card it shows up as only 300 MB.
When I open the folder it only shows one mp3 file.
When I select all files on the card it shows that it's only 300 MB.
- I tried searching for it by file names
- I've got "see hidden folders" enabled
Mind you, I do have a backup,
just wanted to see to it that it doesn't happen again.
Update: It happened for a second time now
I formatted my sd-card and while I was copying 2 mp3 files from my computer to my sd-card, (all the files were still there) a message popped up stating that it failed and I should check if the file wasn't protected
After the message popped up all of the files inside the folder were gone (including album art)
Again, there is little free space but all the folders combined equals no more than a few hundred MB.
It would be appreciated it if someone could help me out
Thanks,

Hi mo.ammi
I work for a company who sell a lot of memory cards and the returns dept see this a lot, you should get acronis disk director and reformat the card as NTFS (most come as FAT32) When the write to the card fails it is usually because FAT32 will not take as large a file for transfer due to size restrictions, NTFS does not have these restrictions.
I have seen this work in some cases, however if it does not solve the issue then i suggest you send the card back.
Hope this helps,

My bet would be it's a fake (not genuine) card. Such issues are pretty common with them.

Do mind that if you do this, the card can no longer be used to flash your device, as that requires FAT32. Also, I'm not completely sure about the normal compatibility with the X1, but I guess you can give it a try.

I tried your method and at the moment it seems stable.
You say it's usually because FAT32 won't accept large files (larger than 4GB if I remember).
But my largest file is an episode of American Dad (100MB)
Anyway, thanks for your help. Luckily it's just a 2GB card

I usually flash my device using the RomUpdateUtility.
Are there any pro's or con's using the card flash method?

I had a similar problem with my sandisk 8gb card but it just stopped working altogether while i was using tomtom, i tried to format with windows and a panasonic sd-card formatting tool but it would not work.
I had to phone sandisk for a replacement yesterday but im still awaiting there reply

i tried using acronis but it only shows my hard drives and not flash drives, would not mind a last ditch attempt to save it if you tell me how??

i had the same problem with a 8 GB card.
installed some tool to format the card under windows mobile took ages and i ran out of battery ... now the card is totaly unreadable. not even windows recoknizes it anymore.
guess its borked now

Hi Flext,
I am unsure as to why your card is not visible by the Acronis suite, have you tried looking in disk management on the OS to check if the PC can see it as attached?
As Angelusz has stated you will not be able to flash firmware with the Card after changing the format, however the Acronis suite will allow you to create a small partition of FAT32 on the same card that could be used for this purpose. I do not know if the Xperia will recognise both partitions and display that you have two seperate cards, if anyone has tested this can they please post their findings.
Regards,
Creamy-Goodness

windows recognises the card in my computer but when i try to explore or format it my computer hangs, forever, then normally displays an error message an hour later....
i originally installed acronis a while ago to create partions for backtrack 3, when i did this i dont remember any other drive except my HD's being displayed maybe its the version of acronis im using???
also my X1 does not see the card at all though, "there is no storage card installed", however when i plug the card into the phone when it is sleeping the phone wakes up???

Hi Flext,
Sorry to say this but i think you card is indeed knackered. Just buy another, they are really cheap these days (even the non faked ones) It would be easier on your own sanity to bin it and move on.
Oh and i'm using the latest version of acronis, just checked but i dont think it makes much difference as it seems to be more or less the same UI and functionality.
Kind Regards,
Creamy

got weird problem too with my sd card i have seen the number of mp3 count on media panel decrease to zero after an update to r2a

Use or not swap file in SD card

Hi, I've searched the forum but found no answer. Searched google and found contradictory answers.
Should I use a swap file in SD card?
What are the advantages and disadvantages?
Thanks

Advantage: Allows more multitasking due to more memory use from the sd card.
Disadvantage: Shortens the sd card life.
If you plan to use swap or A2SD, I recommend getting a class 6 sd card. Some people are opposed to swap, some people are all up for it. It's just up to your preference. For me, swap is just nice that an app doesn't close when I'm using another app.

A good answer but slightly incomplete. Most sdcards have wear leveling so having swap on your card will do very minimal damage.

If you want to have a swap file (swap.swp) this could possibly corrupt your fat partition. This is based on my own personal experience of course. I recommend use a swap partition honestly.
Just imagine mounting your sdcard to your computer to transfer files while your phone is still attempting to write to /sdcard/swap.swp. This can theoritically cause problems. And you don't want problems on your sdcard. A seperate partition is the safest way to go. But again... just my opinion.
Note that if you are using a rom based on Cyanogen's kernel (such as 5.0.7 or 5.0.8) it is NOT recommended to use swap at all. It will slow down your phone causing more problems than what it's worth. ('Swap grave' is how he put it.)

If your system is writing to the .swp while you mount/unmount the sdcard it can corrupt the card. It's better to use the partition.
In addition if your system is setup to use the swap.swp on your fat32 partition and you mount it to your computer, what do you suppose would happen to your system since it can no longer have access to the .swp file?
Again... not a good idea.

I don't see how unmounting the swap partition is any different from unmounting the partition with a swap file on it.

Just say no!

Your computer's OS can only mount the filesystems it supports, for example OOTB Windows only supports FAT and NTFS, so it can't do anything with ext. Anyway, linux-swap is non-persistant, you can't mount it to view the contents, my understanding is that should you mount it on linux, the swap partition will be ignored.

But the point is that they're all unmounted before the SD card can be shared with the computer as a mass storage device, so I don't see there being any difference between a swap partition and a swap file.
Besides, Swapper has a default "safe" option that unmounts swap before sharing SD with the computer and remounts it after disconnecting.

I wasn't aware that Swapper has such a feature but that doesn't change the fact that if your running say ~200mb of RAM with ~64mb of swap and with all the multitasking that you're doing you're using up most of it... so say you have only ~10mb free. Then all of a sudden you pull out your sdcard. What do you think happen will happen? Your phone was reading and writing to that card! Do you think that's healthy? If Swapper unmounts it before it shares the sdcard with the computer then it may be better for the sdcard but I don't see how that can have a positive impact on the device. However if you have swap on a seperate partition the only way to run into this problem would be to remove the card from the device. Even if you mount the sdcard to the computer the phone still has access to the swap partition just like it still has access to the ext partition (if it has one).
I don't know about you but I have a 16gb class 6 card and it's a pain in the butt to restore my data to the fat partition so I would rather not have anything read/write to it unless necessary and to have something constantly reading and writing to it is a really bad idea in my case... but maybe you have a ~2gb and reloading the data may not be annoying to you.
Anyway... stick with what works. I've tried them all and based on my own experience I suggest the separate partition if you are going to use swap. But hey... what do I know?
By the way... do NOT use swap on CM5 or CM6. It may help at first but you'll be enroute to digging "a swap grave" (quoted by Cyanogen himself).

Your phone will ONLY share FAT when mounted to PC
Ext and Swap are still running on the phone(app2sd how do you think apps keep working after mounting?)
Same deal with Swap...
I personally do not use Swap although i do have a 128mb Swap Partition.

Android routinely kills processes as part of its "task management", and the apps are expected to save their state using "Bundles" so that when you restart them, they restart in the same state they were last in. Is unplugging the swap more harsh than killing the app?
Once Android determines that it needs to remove a process, it does this brutally, simply force-killing it. The kernel can then immediately reclaim all resources needed by the process, without relying on that application being well written and responsive to a polite request to exit. Allowing the kernel to immediately reclaim application resources makes it a lot easier to avoid serious out of memory situations.

Hmmm. When you mount the SD card, the entire SD card is available on the computer, including the FAT, EXT, and swap partitions, but the phone can't access the FAT partition?
I can see the contents of the swap partition from the computer with "sudo cat /dev/sdb3", but the phone can still access it? If I run "free" on the phone, it still shows swap, and the used size still changes, so I guess the phone is still using it, but the computer can see it at the same time, too.
In that case, I understand why it would make more sense to use swap partition than swap file.

What does that mean? Where did he say that? In what context?
I'm using swapper with CM5, and it's like buying a new phone. It greatly speeds up the phone's responsiveness.

I dunno why you can see all three partitions. When I've got my swap and extra partitions setup and mount my SD to my computer, the only partition that shows up is the FAT one, using Windows that is.
As for using swap, a quick Google search will show you a number of threads stating that the only time you see a real benefit from it is on the G1 an older mytouchs with the lower RAM space. Actually most say that using compcache is the better way to go if you've got the extra RAM space.

And I'm aware that 2.2 automatically kills idle apps, which is all the more reason that you do not need swap.
And your phone cannot access the /sdcard or /mnt/sdcard partition while it is connected to your computer as removable storage. Try it.
Try downloading something to your sdcard while it's connected as removable storage. You can't. Your phone does not have access to the sdcard. In fact... while it's mounted to your computer go to settings SD card & phone storage settings and tell me what it says under Total space and Available space.
Do NOT use a large .swp file because your phone is constantly writing to the sdcard! All it takes is a single instance of removing it without unmounting it and you will have corrupted the entire contents of the fat partition. That is what I mean by restoring the data on the sdcard. I use an ADATA 16gb class 6 sdcard and each time that I tried with the .swp file I ended up losing my data because of random kernel crashes, dead battery, unsafe sdcard mounting etc.
But if you are really convinced of otherwise then go on ahead but I'll tell you right now, I will refuse to help anyone that never listened to my advice the first time. If I give a warning and if someone doesn't listen then it's all on them. I will personally refuse to help them and I wouldn't blame anyone for doing the same. Cyanogen warned users not to use swap. So those that have issues shouldn't complain to him or anyone else because it's their own fault.
All quotes from Cyanogen on twitter. You should follow him and learn something.

You can actually access the swap partition from a Linux based OS such as Ubuntu/Live CD.
When you mount the sdcard you also have access to the ext2,3,4 partition if it's available.

See what I get for being Windows exclusive? Edited my first post to be more precise with my wording.

Yes, this is the standard response in threads like this. "Android automatically manages tasks and memory, so you shouldn't try to second-guess it". But, empirically, swap makes the phone run better and faster.
If you switch to another app from the browser, for instance, the browser almost always gets killed, and then it has to reload the entire page from the Internet when you switch back to it. This takes wayyyy longer than reloading the state from swap, and causes problems when the web page is dynamic.
Many apps take much longer to start up than they should, or don't actually return to the same state when they're restarted, and swapping them out works better. I'm guessing the people who are happy with the stock system use their phones differently.

Yes, I already agreed with that. Swap file is a bad idea since it's inaccessible when you mount on the computer, but swap partition still is. Agreed.

Annoying external SD issue

Hey there guys.
I have the latest european stock firmware on my SGS2. The issue persists since I bought the thing: I am using a 32GB card and I cannot get the phone to see media files that are on it. I copied 2 or 3 movies on the card, which was of course formatted before use, and it says that the space is taken but I cannot see the files either in file explorer , or in Gallery. Any idea why? Maybe it doesnt fully support a 32GB card?

Are you using fat32? If not... use it

Maybe the movie is too big for the file system. Every file system can handle only files up to a special size... Try to reformat and check if the video is converted the right way... Take aybe 10 minutes of the movie, convert it and transfer it to your phone to be sure about the file size thing... Officialy the phone is compatible up to 64gb.

Unfortunately is none of the suggestions. Although I can use the card perfectly well on the laptop, it doesnt work properly with the phone. Must be some incompatibility. Which sucks, since it s a 32GB card... Thank anyway

Are you sure it's really a 32GB card? Many cheap cards that one can buy on places like eBay are fakes -- low-capacity cards hacked to look like high-capacity.
There are some test programs that will tell you if the card is really the capacity it's supposed to be. On the phone itself, you can run SDCardTester (free from Android Market), and on the PC you can run h2testw.

Yes this might be an idea. It is unbranded , but on laptop it shows 32GB. Hmm.. I have it from a sony ericsson xperia from a trusted person, but on the other hand...who can you trust? I will try my 4GB card and see if it shows my movies.

Cannot format SanDisk 64Gb microSD

I have a 64 GB microSD card and it was working fine, I had it almost full because I do travelling sometimes, but all of a sudden, I cannot delete the contents and I cannot format it from the phone or pc. I did some research and I saw that this has happened to a lot of people, mostly with galaxy phones. I have ordered samsung 64GB card now but is there any way to format the card and empty its contents?

Be careful when/if u end up getting it formatted, ive had a few come back and go corrupt after putting files on it thinking it was all cleared and fixed. Im not sayin....im just sayin.

Same here as well. All my personal data is on the card, including bank passwords etc. I will have to go through quite a lot of hassle to change all the passwords and there are family pictures etc as well. This blows.

Same problem here, with a SanDisk 64Gb Ultra microSD. Failed to delete files one day last week - they'd come back after a reboot. Sometimes with a corrupt filename.
Now completely write protected. Zero issues prior to last week.

this is à very common problem!
but there is one solution
try to format your sd card using linux (ubuntu).

No joy for me. Tried last week - writing zeroes using DD proved ineffective, as did the official Windows SD formatter application.

Also to note that the cards have a low number times that can be written to then the Flash memory goes and the card becomes ready only I had a 64GB card which i used for 6mnths and now can only be used as a backup grrr

It didn't work either. GParted cannot format it and gives an error message.

If it's the same problem mine had, then nothing is likely to help. If the controller on the card has decided to write protect the storage because of impending doom, there is nothing you're likely to achieve with most user accessible tools.
Get in touch with Sandisk - I found the staff to be brilliant. After a couple of emails back and forth, I had permission to drill through the memory ic on the card to protect my days, and an RMA number to return the product. Sadly I have to return it to the Czech Republic (awkward as in in the UK - somewhat expensive) - but is less hassle than dealing with many retailers.

Nokia 6 with SD card?

Is anyone using their Nokia 6 with an SD card?
How does it work? well? Can you move pictures/videos/documents to the SD easily?
what size SD? micro?
Thanks!

I have a 200gb microSD card in my US Nokia 6. All my apps can read files on the card, but because I set it up as removeable storage instead of simulated internal storage (it asks you to choose after you insert the card), only apps that know to request special permission can write to the SD card. Most file managers I've tried can handle writing to it, other apps like text editors are more hit and miss.
I think if I had set it up differently it might work with more apps, but I was worried that would result in it being encrypted and getting cluttered with random data files from every app. If root is ever figured out with this phone then I should be able to have better control of which apps can write to the SD card.

It is easy to use. When I taking photo, all image files stock on SDCARD.

Can it read more than 200gb? I'm thinking of shelling 256gb max but might go for 128gb or 200gb for sandisk as I have files need to be moved. I keep looking at websites that the phone can only support of upto 128gb. thank you

I'm using a class 10 32GB SanDisk SD card with mine and it runs smoothly. I can move a lot of files at once to it and expect transactions to be generally quick. Make sure to set it up as external media otherwise you'd simply be merging the card with your internal storage and won't be able to control what goes into your card. Root is a must for this phone it seems.

It's a must for most phones... Pity there's no ay to do it with the locked bootloader...
