[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.

Micro SD

hi, i have a micro sd 4gb class 6 and my phone works fine, When i put the original micro sd 8gb class 2, the notification icon of "preparing SD" doesn't dissapper and when the screen go off i can't turn it on because never shows me the screen, only the inferior buttons lights on (nothing i can press) and i have to pull over the battery to make the phone works, i put a micro sd 8gb class 4 and the same happens, i've tried to increase the cache memory to 2048 bytes using "SDBOSTER" and nothing happens with the micro sd 8gb, but my micro sd 4gb works faster.
Can anyone help me to solve this problem? i want more space in my external memory.
I'm using original eclair 2.1-update ROM

Hey jp23,
I recently encountered this problem with my stock 8 GB class 2 card, while transfering files in bulk to the card. I use linux on my laptop and there is a known bug in one of the drivers which causes failures while tranfering large amounts of data in one go. For me it caused the same issue, and thats usually because the card is temporarily corrupted.
For me the fix was buying a microSD card adapter and formatting the card once through the computer and not the phone. I also bought a 16GB class 4 card in the process.
I suggest formatting your card via a card reader or adapter and then trying it on your phone. Although I find it odd how both of your cards can have the same problem. Hope this helps.

I've tried this before and works when the card storage it's <1gb, when i put some mp3 files and pass 4gb or more the same thing happen.
i don't know what to do...

Did you do a scan and repair using windows? That fixes it for me

format it with LLF low level format from hd guru, it always fix my sd card whenever it corrupted.

My card it's not corrupted, i've checked that before.
I bought a micro sd 8gb class 4 and set format as fat32 and put it on the phone, then i connected to the pc using sd adapter to put some music and videos, and when i put the sd back to the phone got the same issue...

I updated to BRAVO yesterday and have no solutions for my micro sd 8gb class 4

i have a similar issue with my 8gb stock sd card too, when i try to open the media gallery or push the media gallery button, my phone shows me that there's a problem with read/write into the sd card... =(
always it says me : "Failed to Read/Write SD Card" and also i cant record any hd video cuze when i try to do it, the video get freeze and stop to record ..
im thinking to buy another sd card, maybe 10 class ..

Here is a reason and fix for this http://forum.xda-developers.com/showthread.php?t=1262030&highlight=failed
But I do recommend getting a c10 card for the speed.

I have same problem, you should update your phone to 2.3, you will out of this.

I just purchased a Micro Innovations Wireless keyboard for my Zaurus-SL5600, but theres a problem; I dont know how to physically set it up to work. I can type with it, and the Z recognizes it fine, but the problem is that the Z has its infra-port on its side, so I cant use the stand The keyboard has it just above the w key, and I dont know how I could rotate the screen.. Does anyone have any ideas?

Too bad with micro sd

[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

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.

[Q] 64GB HD Card on Lollipop ROM - What format should I use?

I have been trying to find the best method for getting a 64gb SD card to work with my phone, and it has not been all that successful. I have formatted in NTFS, exFat and FAT32, all with varying degrees of success. Either copying files over leads to data corruption, or I cannot write from and to the SD card when it is being accessed by my device. Any help would be greatly appreciated.
I am currently running CMPrime ROM v1.1Beta with the included kernel. I have also tried using it with Unnamed Kernel.

I just received my Samsung 64gb EVO MicroSDXC UHS-I card this morning. I popped it into my phone and it asked me to format before I could use it. So I clicked yes and then after that it just worked.
I am not sure what would be different for a custom rom as IU use the offical Lollipop 5.0.2. It shouldn't be much different though.

FAT32 is your best bet. I have a 64GB Lexar card formatted in FAT32 working fine with Titan Prime.
It's possible that something is wrong with the card. Does the card work fine in other devices? What brand is it?
Could also be a hardware issue with your phone, have you tried other cards?

Use fat32 no other file system

I bought a no-name SD card from a Chinese manufacturer, because I figured "why not." I know quality of SD cards vary across manufacturers, but since it's an established technology and relatively easy to make, I thought it'd be worth a chance. Some quick Google-Fu showed that it is not a completely isolated issue related to SD failure.
I have a 32gb card that I'm using without any issues. I'm asking specifically about 64gb, because 32gb seems to be the max size for external storage.

I usually give ROM info, because it is common courtesy for dev communities. I have read that formatting through the device only accomplishes a rather crude job, and that file structures can be unsound. I know FAT32 is the standard, but it is an old format that has size limitations.

But what about the limitations regarding max. file size and data transfer speeds?

I believe you should be able to use NTFS or exFAT with the kernal you're running, though I don't know if there might be any bugs or compatibility issues with some cards. If even FAT32 isn't working correctly, my suspicion if that you have a bad MicroSD card. As a rule of thumb I always buy brand name from reputable sources when it comes to microsd cards. I know those cheap ones look tempting, but the quality issues with them are legit, so it's a real crapshoot.
And yes, you'll run into the same old limitations with FAT32 in terms of file size, etc., but I use it anyway since it has the widest support across devices and I sometimes swap my cards.

I am inclined to call this a bad SD card, but I want to rule out all other possible reasons. Null Hypothesis and all that.
In terms of performance of FAT32, it is registered by the ROM, and it is visible in recovery. But my music files are not readable in Google Music or any other music app. I've tried moving them to /sdcard1/media/music and it is still balls. This kind of behavior leads me to think that it is an actual formatting issue.

Max file size for fat32 is 4GB-1byte. Should be not a problem unless you plan on putting e.g. large hd-movies on the card. Speed isn't affected by the partition type (actually it is, but it's negligible in this case). No-name sdcards are often manufactured with low quality check standards. They sell cards that would normaly get tossed into trash. I use a 64gb card with no problem whatsoever. On windows use http://www.easeus.com/partition-manager/ because windows will only allow up to 32gb. On linux use gparted.

I occasionally save audio recording/mixing sessions as OMF files, which can end up being really large, particularly if I export at 64-bit sampling and 96khz frequency. So the 4gb limit can be a bit annoying to deal with, in that regard.
I wasn't aware about the cheaper SDcards potentially being of b or failed stock. I'll probably buy a new card under a trusted brand, and report back.

Acquired a Sandisk MicroSDXC Ultra UHS-1 64gb card. Tried using it in my android phone. I am able to load files onto the SD card as before, but I still experienced the same issues with Media Scanner failing to account for my music files on External SD. Worse yet, my Titanium Backup files became corrupted when trying to access them via the device. I did a Nandroid Backup and tried a clean install to rule out any potential conflicts with my ROM, only to find that the issues remained, and the Nandroid disappeared from the TWRP backup folder.
At this point, I'm starting to think that it's an issue with the phone itself. WHY CAN I NOT HAVE 64GB OF SPACE, MOTO G!!!?

I bought a sandisk 64gb card off amazon on black Friday, immediately put it in my phone and let the device format it.
Later, I put the SD card in my computer so I could create a 2nd partition for ext4 storage.
The phone had formatted the card Fat32...has been working just fine since then.

When I try to mount the SD card in the phone, it does not register. It only works after I format to FAT32 using TWRP. So I will probably try that.
So 32gb in FAT32, then 32GB in Ext4, and leave back-ups/other files there?

64 card files wont all play
Hi I have a new moto g, I also put in a 64 sd card, while the music files seemed to play fine, video and other files the phone reads some of them not others, I put the same file internally and on the sd card and it reads the internal version of the file. I gather from this forum (though I may be wrong) I need format the sd card, I have no idea how to do that, any help would be appreciated.

My understanding is that, if you have a FAT32 SD Card, then larger files (4gb+) cannot be read. ExFAT and NFTS should solve this problem, but I am still dealing with issues of reliability with my card accessing my music files post-formatting.

Finally discovered the problem. I downloaded SD Insight from the Play Store, and I found that the SD cards I got off ebay were invalid (including the Sandisk SD Card). I picked up a PNY High Performance 64GB Micro Secure Digital Extended Capacity (microSDXC) Flash Media Card from a local computer store, and after formatting to FAT32, everything works.
Moral of the story: buy your **** from a store.

I'm currently using CM 14.1 20161225 with a 32 GB SD NTFS formatted and experiencing some weird problems with Camera/Gallery, Music, etc. when on the SD.
So before I go back to FAT32 on a 64 GB SD I now have I would like to ask if anyone can comfirm exFAT would be working fine on titan CM14.1 or LineageOS?

That's strange, i have no problems with mtp in win7, looks like win10 doesn't worth updating. Btw, i tried exFAT before and it strangely limited file size to 4 GB like in FAT32.

System properties not responding. SD card Missing! Had happened 3 times.

Here's the story and info.
I got the Blu R1 HD (prime special) went down to Target and bought thier DANE 64GB CL10 MicroSD for $20. Plugged it in and formatted it as internal storage. (A cautionary not then said, "if formatted as internal memory SD card will ONLY work in this device) I chose, who cares and continued.
Worked great for a day or two ... but then it happened ... it went missing! All the apps and data was gone. A notification popped up and said, "Transcendent SD card missing. reinsert this device". I did as the all knowing phone asked but to no avail, it wouldn't recognize it.
I rebooted the phone and a massage popped up saying "system properties not responding. Wait or Quit" I've tried both options, doesn't seem to make a difference.
I tried reformatting it in the phone and it wouldn't unmount. Tried on our computers (both pc and Mac) and neither computers were allowed access to the sd card to reformat it.
I then returned the sd card thinking that it might be flawed, got another one from Target and it worked great ... for about two weeks... Then went missing.
Did everything mentioned above. Got the new one and it worked for 4 weeks, thought my problems were over ... then the SD card ran away again and is now currently missing. The phone does not recognize that there is a sd card when looking for it in a file explorer. In settings it says the sd card is corrupted.
Is my phone messed up? I'd it the brand of SD card? Is there a way to make the phone recognize the sd card?
Please help me find my missing sd card.

Same problem, SD Card is showing as corrupted. I have it installed as internal storage and have for over a month with no problems. SD is a Patriot LX 64gb. I haven't changed anything on the phone. I have not fine anything but reseat the SD. Any help is massively appreciated!

Maybe the problem is using a 64GB MicroSD Card. The phone specs say it's supports up to 32GB only.

That is incorrect it supports 64GB SD, many report success with 128GB cards, so I doubt its an issue with size...

Okay I caved and tried to reformat it, and all it does is fail, or drops off half-way as though I had removed the card. If I try to put the card in my computer or any other device it just straight doesn't exist, doesn't even say it isn't compatible or anything, just straight doesn't exist. Think the card is just bad, gonna return it and get a new one, will see what happens.

I have had a SANDISK Micro SDXC UHS-1 64GB CARD in mine for almost 5 months now and no issues.

I see I'm not the only one with this issue, although mine is a little different... I got a generic 128gb card and plugged it in, has been issue free for months... BUT, lately and for what seems like no apparent reason, the card guess missing... Rebooting the phone sees the card again with all apps and photos intact. It could be weeks/days/hours/minutes before it happens again... Shortest turn around - about 10 minutes. Longest - about 2 weeks... Haven't tried plugging the card directly into my computer yet, but when it is mounted on the phone it works fine (until it goes missing). Thought maybe it was because it was a cheap card...
