Has anyone noticed slow SD transfer since upgrading to ICS?
The simple copying of files from PC to SD has become unbearably slow. Even after fixing the SD (from the dialog that came up, not sure if it actually did anything) no change.
Taking the SD out and copying direct is very fast.
It wasn't like this on Gingerbread.
My Sensation is stock o/s, not rooted, I use Sense.
Note: I had posted this a few days back on a thread about reboots, no responses so reposting here as it's really a separate topic, hope that doesn't violate rules, etc.
With root, you can increase cache size your SD to 2048kb. You can also buy a faster card. What class you have now?
I had a similar problem. My file transfer was only a little slower on ICS, but it was noticeable. On top of that, my SD card would unmount without warning during larger transfers. This was on a Lexar 32 GB Class 10.
I ended up pulling the card a week ago, backing up the contents to my PC and just reformatting the thing in my PC as FAT32. It came as FAT32 from the factory, but I've read a lot of posts where people fixed their SD errors by reformatting the card in a PC.
So far, no unexpected SD unmounts, and speed might be better. Or it could be my imagination.
Not sure if this will fix your problem, but it's something to try if you have no other leads.
I have a class 10 sans disk. Didn't notice any slow down going to ice really.. Not that I can remember what GB was like sd card was misaligned apparently according to 4ext. I formatted my sd with my PC, hit the default format settings, not quick format then stuck it in my phone.
Thanks for the replies, they don't sound like my situation.
My card was always secure, and the copying is vastly different inside and outside the phone, so I can't fault the card.
Something is buffering between the phone and the card. The difference is night and day.
I can just take out the card and copy direct each time, but that's kinda stupid and inconvenient, there's got to be a better way. And I'd be surprised if it were only affecting my phone.

Is anyone else having issues with their sd card corrupting? I have an 8gb class 6 transcend card and it has corrupted 3 times in the last month. I always unmount the card in windows before unplugging the phone. It seems to do it when I'm writing to the sd card from the phone.
The first time I noticed it was when I deleted a picture with built in photos app.
The next time was today when I made a nandroid backup before applying an update (theme). The nandroid backup finished and when I went to apply the update it came up with an error (I didn't reboot between the backup and applying the update). I reset the phone and the sd card was unavailable.
At one point I did have the card partitioned with the apps on one partition. When it corrupted I reflashed the phone back to 1.42 and left the apps on the phone. I went back to one partition and left it at that (fat32).
I don't know if I just have a bad card or something else is going on. I never had any problems with 1.41. However because it did it while doing a nandroid backup would that rule out the software version?
I would like to find a solution, as I don't trust the card anymore without backing it up frequently.
i've had it happen once (files names corrupted) but assumed it was down to the card as i had the same happen when it was in my N95, i've now bought a new card and i'll see how it goes.
When mine goes down, it seems like it kills the partition. When I open a disk manager I don't see a partition on the card anymore.
Hey axion,
Yea your card is pretty much dead... this also happened to me yesterday on my 4 gig card... yyour card will still work however reformatting or creating anymore partitions won't help bring it back.. for future update.zips or recovery boots upload your update files to your stock 1 gig card.. remember to always safely remove hardware with any card mounted to the to a computer..
YES - and not only have I had the same problems, it's with the same brand card! Transcend 4 GB Class 6.
My phone started having issues where I installed an application and it would act wonky, then if I tried to reboot it'd lock up into an infinite loop.
The last couple of times, I solved the loop by doing a fsck on the partition in GParted (booted into a GParted Live instance from a laptop using a USB stick). The problem reoccurs though, making me think there's something problematic with the card.
There's an app in the thread on the cheap 8 GB cards (of which I'm holding my recently received shipment . There's an app in that thread used to test write performance, but it does some crude error checking, and I had an issue when I did that test.
I'm going to do a partition clone and report back.
my dodgy card was 4GB Kingston, one interesting problem i had with it was video refused to play, i could read and write the file fine but android would refuse to play it and meridian video player would report the wrong pixel size, time and codec which had me confused all last weekend.
I'm also frequently having problems with my 8gb card (http://www.newegg.com/Product/Product.aspx?Item=N82E16820211341). Every few days I find myself firing up Ubuntu to fsck it and I always find errors. I often discover them when looking for a file on the phone (I usually do a find / | grep whatever and notice that I get "stale file handle" errors).
Should I get a newer/better card? I'm happy to pay more for a better one. I didn't know this brand, but it was the only class 6 I could find. If Sandisk made a faster card I'd get that, but I can only find a class 2. I have a 16gb Sandisk but it is only class 2 and therefore not good for apps, which is what I'm using the sdcard for.
If anyone can recommend a better one, I'll give it a try.
Does a 16gb class 8 exist yet? What about a 16gb class 6?
I just moved to the same card you have, mlevin - so I'll post back my experiences if I'm seeing anything.
I'm wondering if maybe moving the caches to SD isn't the greatest idea, since these devices aren't meant for continuous writes. If I have more issues, I might just move the caches back to the onboard memory.

Yeah, that worried me as well, so I moved my caches back to the main storage and only have app, app-private and data symlinked to the card.
If you are having problems after moving apps and data to your ext2 partition, you have to push the original init.rc and mountd.conf back onto the phone so you can wipe to card fully and restore it to the FAT32 file system.
I had a similar problem on my tmobile wing (variant of the Atlas which is a modified version of the Herald) running Windows Mobile 6 and Windows Mobile 6.1. I think it was also when I used the SD card as a place to store cache for PocketIE. Maybe that's the issue, using it as cache storage. (This is my theory, not something that has been confirmed.)
g1 sd card deletes itself
I am on my 4th sd card. I am not sure what is corrupting/deleting my data. I can copy over some music/video/pdfs/wtfevers and it'll stick around for awhile. Then BAM, music folder empty(had 1 gig of music in it). BAM, 1 of 3 video files corrupted. OH wait, now all 3 are gone. awesome. I keep a backup on my pc so I can copy it all back over once it goes south. I have the doodledroid drawing app on my phone and the folder will go corrupt - not allowing me to save an image until I delete the folder so it can reinitialize(create a non-f'ed up folder). Also, my picture thumbnails get f'ed so I have to delete that folder so the G1 can remake a new non-corrupted set. My PDFs disappeared about 3 days ago. Cards all formatted fat32. blah.
Frustrating.
I have root
kila-user 1.1 PLAT-RC33
Anyone else find a solution?
BTW, my sd cards were:
sandisk 2gb

PNY 4gb (current)
Lexar 4gb

mlevin: I have that card. It's been fine...until I believe the other day. I was running 5.01H w/ apps to sd and my battery had died so I charged it. Upon turning it on the android screen kept looping as though it wasn't mounting the card. Worse came to worse and I had to end up reformatting the card and starting from square 1. Now that I reformatted it, I'm getting "insufficent space" errors when trying to install paid apps even though I did everything right.
I'm wondering if it is the card.....
All of a sudden apps on storage card fail to load.
After a few reboots they reappear at random, but disappear again on reset.
Did not have that problem with stock, but after flashing Infused 1.14 (and on) the issue appears even with the (rooted) stock rom.
Any ideas?
I am trying to determine if I need to return and replace the phone before I lose the option.
Thank you in advance.
Answering the question by myself, in case others encounter the same issue.
The external card had something corrupted, and when the system was mounting it, all mess ensued.
Backed up all the data and reformatted.
System appears ok for now
I just had this same problem or at least something very similar to it. Initially I thought it was the 32GB SD card being too big since I read Android had a 16GB external card limit. But those posts were from a year ago and when I searched deeper I read that 32GB cards were being use without size problems now. There was one issue that seemed to affect some people and that was that android could have problems formatting a card that big and that's how I installed it in my Infuse initially- I let the Infuse format it, then popped in in my Macbook Pro (in OSX) to copy over the contents from the previous 8G card. I believe I have hidden files set to show, so I should be copying over everything- though, could this method of upgrading the card be a problem too?
It worked for a couple days, but last night during a reboot I tried to access the app tray and didn't know the card was still being scanned. It froze and I couldn't get past the secondary media scan after many tries. I didn't realize that apps were being automatically installed to the card.
Anyway, I was gonna return the card, but after reading your post, I'm thinking again about corruption due to poor formatting as the problem, so I'll try it again when I get home. Thanks for your post. I really want to be able to use this larger card so I'm keeping my fingers crossed this will solve the problem.
BTW, how did you format the card? I have Win7 x64Pro on my MBP as well if I need to use windows, but did you use FAT, FAT32, ExFat? I'm still a 'droid noob ;P. Thanks again!

I am having a problem finding thins in "Files" and "Astro" on Tmo GS2. This is a general ? that could happen to me or anyone on any phone, I assume, so I put here. I hope its ok
I just upgraded to a 32gb sd card class 4. I was told it was good. Its a
Sandisk. I was going for a class 10, but people said it was not only not necessary, but it would slow down occasionally ... but be fabulous with games and video
regardless of that, i then looked for a class 6 Only found no names and someone said its better to have a Sandisk at a lower class than one class higher from a no name'
Well I don't know if that has to do with my problem. I can't find things. I search, nothing. I use Astro, now this is weird. Nothing. I plug into the computer, it is listing the phone as TWO separate drives. THis has never happened to me in the past and never heard it mentioned
I am sure it is nothing wrong, but a settingn somewhere and I can get all the files combined
also, I am assuming all of those file explorers on the phone cannot look into the hard drive of the phone? Is that correct, no other excuse? And this other "drive" I am speaking of, one can only assume it is the hard drive
Well in any case, if anyone could straighten me out, help me, etc.. I'd be most grateful
happy Halloween All

I have the same problem on my eeepad transformer
I bought a 32 GB microSD card from Trascendent. When I nstall apps that are supposed to be installed on the external SD card it does not do that. It goes to the internal SD card. When I sync it with my PC it shows both devices. The SD card is completely empty except for a folder that reads LostDir. How can I get the external SD working?
Any pros or mods, please correct me if needed.
The GS2 does it differently keeping them separately
You can choose on your phone which apps to store on phone or sd card. You can go to settings/apps/ and select move to sd card etc.
some, however will not go there no matter whatt
when you go to usb mode on the puter, you will see two drives show up
One is SD CARD - this is actually your PHONE
The OTHER is labeled EXT. SD CARD (for external) - This is the actual inserted sd card
On the SD Card, you will see in its contents in the computer window the external sd folder within the sd card
...even tho, on the far left (windows 7 and others) you will see the two drives listed separately
That is the best I can do. I understand it enough that it works. I may even understand it better than that but just not able to explain it
Enjoy
EDIT: Answer at bottom, but my OLD card turned out to be the defective one.
I just upgraded from a Sprint Samsung Epic 4G to a Sprint Samsung S4. My S4 is already rooted and has TWRP.
To go with my new phone, I bought a Patriot Micro Mobility 64GB Micro SDXC card. The card is class 10 UHS-I and is obviously formatted exFAT. The first thing I did is format it in the phone (which curiously gave me a little bit more free space), unmount it properly, insert it in the little USB reader it came with, and then use Win7 to copy the full contents of my old SD card onto this one. The next thing I did, from cygwin, is a full "diff -rl" between the old and new card.
To my surprise a single file differs, from a single nandroid backup instance: clockworkmod/backup/2013-06-02.21.44.05/system.yaffs2.img If I do a cygwin "cmp --verbose" I see what looks like 1-bit differences, always about 240MB into this 251MB file.
If I rename that file on the SDXC card and copy it again and immediately "cmp" it, it compares fine. If I then do a full diff again, the file "changes" and is now different -- with a different number of differences from the renamed first copy. (Yes, those two files differ from each other on the SDXC card.) I can do this as many times as I want, getting the same behavior each time. Once I get differences, it doesn't seem to change again after that. My guess is that it is corrupted on copy but when I do the first "cmp" I'm not reading from flash but reading from the Windows file system cache. And that the full diff effectively flushes that cache so I see what is really on the flash.
EDIT: After much painful investigation, I discovered that it's not the new 64GB SDXC card that's defective. It's the old 32GB SD card that is defective. Only one file gets corrupted when copied off of it. I took the new SDXC card out of the picture by copying the one bad file to my hard disk, then unmounting the SD card, then remounting, then again copying to my hard disk (different filename), then repeating. I get different file contents every time I do this. This happens even with different USB readers.
I've never heard of such a thing, but this card is two years old. Looks like I need to make one last nandroid backup of my old phone, since this one gets corrupted when copied off the SD card!
If anyone has seen anything like this before, I'm still interested in hearing about it.
Card is a Sandisk 128GB Ultra MicroSDXC A1 card.
Card is formatted exFAT.
Card can be mounted, opened, and read/write with no problems via my laptop when plugged directly (SD slot).
Android (LG G5, LineageOS 15.1) says card is corrupt, is trying to make me format. Card initially set up as "Portable Storage".
Took FOREVER to move music onto this card, as artists had to be moved one at a time or transfers would fail, so I'm trying to avoid formatting.
I've tried rebooting the phone, repairing the file system using TWRP Wipe command (fails with error code 1), and mounting with a clean eject via Windows 10 on my laptop using the SD card slot. Nothing has made an impact, stupid phone still won't allow me to use the card.
If anyone has any ideas why this is happening, or how I could potentially fix this without having to wipe the card, I would appreciate it. This thing has been a PITA since I got it, I thought it would be awesome having such expandable storage on my phone (I'm a weirdo who doesn't use streaming services) but I've had nothing but problems so far. I have to be careful with how I transfer files onto the card or the transfer will take an (appropriately) long time, act like it works, but then the file just won't be there. Now I've finally gotten the card loaded up, and after a routine phone reboot a few days ago, the Android OS is trying to say it's corrupt; This is also making me worry that this will continue being an issue in the future.
Running "chkdsk E: /r" on my laptop is revealing a couple minor corruptions inside the directory, and volume bitmap. It's hanging on verification/completing now.
Is it possible that I have a bad SD card? This thing has seriously done nothing but suck since I've been trying to use it.
Edit: Unless someone tells me otherwise, I'm pretty sure this is a bogus/defective SD card. I simply cannot believe that flash memory would perform this badly. I'm going to return this card (bit of a PITA since I ordered it online) and buy another one locally.
