External SD Card Slows Down OS, Eats Battery - Captivate General

Hi Guys,
I'm not particularly "new" here, I browse a lot but I've never posted.
The issue I have been seeing is related to using an external SD card in my AT&T Captivate. I bought the phone in Jan 2011 and the SD card worked fine for a while, through various ROM flashes and such.
But finally, I looked and all my music was gone and the notification came up and said "Damaged SD Card", so I reformatted it, reloaded music, all was well.
Then I noticed my battery life went in the can, and performance was slipping. And the SD card kept re-damaging itself. So I put everything on my internal SD, pulled the Ext. and noticed my battery life more than doubled and my Quadrant speeds went significantly north (3000+).
The card works fine on my computer consistently, it is a 4GB Sandisk Mobile Ultra Class 6 so it shouldn't be under-rated for the phone.
Any ideas?
Thanks,
Zac

3000+? what rom are you running?

Also, have you tried formatting the card from the phone or the PC?

I was on CM7 when I ran 3000, ICS 4.0.1 ran around 2850.
And I've formatted the card in the phone and in the computer, neither option fixes it.

May I suggest trying a low-level format using SD Formatter from the SD Association?
SD Formatter
I've heard of it fixing odd problems with SD cards. Its worth trying.

Thanks Red, I'll give it a shot

Did you give it a shot? I'm curious if this worked as I might need it in the future.

[Q] LG P500: microSDHC & phone display issues

I bought a new microSDHC today - 32GB Class 10, A-data - because I'm selling my iPod and want to put my 23GB of music onto my phone.
The problem I have is that since I put the new one in, my phone sometimes (well... often) becomes unresponsive after the screen turns off. Even the power button doesn't do anything, and I have to take out the battery and put it back in just to turn the phone back on.
Has anyone else experienced this? As you can imagine it's incredibly frustrating. Using the GTR-X 5.8 ROM (based on CM7.2).
Iam sorry to say that the P500 only Supports SD Cards up to 16GB with Class 6. All above can (but not must, its a little bit wird) resolved in strange kind of Errors like in youre case.
That's interesting - where did you find that information? I did some research before buying the card and nothing indicated that. It's working fine now though, I just fiddled with it a bit and made sure it was aligned properly.
Well try this and see if it helps
First use normal less capacity sd, if you have otherwise skip this
1. Reflash the rom or any other better rom(there is better version of gtr rom)
Now put back 32 gb sd
2.download app sd booster from play store
3.set cache 2048 kb
4. check now if everythings fine

There is no relation between the SD card and the phone not responding issue.
To isolate the issue you can remove the SD card and try again.
By the way, LG Optimus One supports upto 32 GB size SD cards. So there is no harm to use 32GB SD cards in your case.
If it is the issue, this could be with your custom ROM update.
You can try the PAC-MAN 19.9.9 JellyBean 4.2.1 recent update. Camera, display and more feaures there. I am using it currently. Except the battery drain issue

minor glitches when playing video from external SD card (Sandisk 16GB)

When I play video stored on my internal storage, it is smooth. I can watch a 90 minute movie video without noticing any glitch at all.
When I play video stored on my external storage, there are glitches. One glitch every 1-2 minutes. These are not big glitches, just a brief deviation that gets your attention. If I listen, I think it is skipping a fraction of a second of the audio. (It may be skipping a fraction or second of the video display also, but my eye doesn't detect it). It's not a huge deal: ...... but just something that I notice and it's a minor irritation.
Since it occurs only on external sd, not internal storage, I assume it is the speed of the sd card. I have a 16GB Sandisk SD card. If I remember right, it's "Class 6"
I don't hear any glitches when listening to MP3's off of external sd, works just fine with no glitch ever.
SUMMARY: no problems on internal sd, no problems on mp3's. The only problems are videos on external sd.
It seems to me that the external sd can't quite keep up with the high transfer rate required for video playback.
Has anyone else seen this?
Any observation about which SD cards do this and which don't?
By the way I'm running rooted 2.3.6 from qkster's package, with Zen's Infusion A kernel. Holo launcher.
I haven't tried boosting to 1600Mhz. I'll try that and report the results later.

I just tried it - no difference. Glitches still occurred with cpu max frequency set to 1600.
You should try to format your external card and then try again.
Also, it could be your external card is to slow on reading
Should not be that slow if it is class 6 though...
Maybe try other card on your infuse with same video file.

Thanks. I have also noted the SD card media scanner runs to scan my external sd card more frequently... almost every time the phone comes out of sleep. I think this symptom coincides with me adding more files to my external SD.
I will try reformatting now as you recommended.
Question: is it better to reformat sd card in the phone or on the pc?
(if on the phone, there is no question of file system... I'll let the phone pick the format. If on pc, I'm not sure what format to pick... I'm using Entropy's kernel with voodoo lagfix enabled... does that mean external cannot be formatted to FAT32? )
The bigger problem is the constant scanning every time I turn the screen on. It was a nuisance, and I think it was draining my battery.
It gave the error message "sd card unexpectedly removed".
There are threads on this for some other Samsung devices.

There was a suggestion Sandisk cards in Samsung devices tend to have the problem.
I transferred my files to my pc, formatted sd in the phone, no problem until I transferred files back... then problem started recurring.
I reformatted in the PC to Fat32. Put files back on. Seems to be much better. But very close monitoring using SD Card Monitor program....

... shows it is still have problems. I'm going to break down and buy another sd card. Perhaps another brand.

Your SD card has problem for sure.
It shouldn't scan that often and it shouldn't say it is unexpectedly removed.
Seems either phone's card reader or the card is very unstable. That is why you are having problems in video files.
If the SD card benchmark program shows that tour SD card is performing bad, I beehive you got fake Sandisk SD card or really low class SD card.
From this point, I believe getting new SD card is the best solution here.
PS. You should put the SD card on PC then run benchmark on PC to see how it performs on PC. If it performs too much faster on PC, then the problem might be your phone's card reader.

Symptom went away with new sd
Before replacing the sd card, I had 100+ sd card events recorded by theSD Card Monitor program in a 24 hours period.
After replacing the sd card, I have 0 events recorded by the SD Card Monitor program in a 24-hour period.
The new SD is a Lexar 32GB Class 10 for $45 at Target. (preformatted as FAT32)
It was cheaper than the $70 32GB SanDisk they're selling at Best Buy.
I'm tempted to say the problem is solved.
On the other hand, one thing I noticed on the old SD was that the old sd symptoms got worse with time... I don't think they were there when the card was new. So I'm not sure if I've really solved the problem or just reset the clock waiting for the new SD to act up under whatever influences degraded the old one. Time will tell. For the time being, life is good. That scanning upon coming out of sleep was a real PITA.. slowed down the phone just when you picked it up to use it... actually dropped two phone calls recieved while phone was sleeping.. I presume because the phone wasn't able to handle scanning and answering at the same time.
Perhaps it was a fake SanDisk. Where'd you buy it from? Lots of fakes on eBay.
I bought the SanDisk (that had the problems) at Best Buy.

Repeated SD failures

Hello, since getting the Photon Q in August I've had two SD cards fail and the third one is showing failing sectors/file system corruption after only a week of use.
I don't run apps from the SD cards, they were mostly used for more storage but I did play music off of them. I can't see how reading mp3s would cause these things to fail. (note I am not adding new songs or deleting current ones)
I've never seen this happen with any other SD card using devices I've owned and wonder if I should get the phone replaced for killing cards? Is there any apps out there to help me monitor I/O activity on the card to see if an app is doing dumb things to burn them out? The file system issues have been knocking out music and causing playback errors when trying to shuffle through songs.
After the first card failed (figured it was just defective) I stopped using them for photos and videos (which is what they've really been meant for since forever), I'm just so confused by this strange behavior.
My wife is on her 4th card now. She has problem with mp3s all the time. Are you using class 10 cards? I'm going to experiment with a class 4 card. But my guess right now is the physical reader is bad. Please update if you figure anything out
---------- Post added at 12:13 PM ---------- Previous post was at 12:05 PM ----------
I copied 3.5GB of mp3s onto an old class 4 4GB microSD. It read every single one perfect. When I used a class 10 16GB, I got a bunch of unknown artists, deleted files and errors.
It might be worth switching to a class 4 to see if it helps you.

The first two were 16GB class 10 cards, this one is a 4GB class 4 that I had laying and its failing too. I format/test the card outside of the phone as well, flash testing tools like h2testw fail when writing to the card and after copying files then running a check disk there are already file system errors.
The first 16GB card lived in my Evo shift error free for quite a while, this 4GB card was once used in that and a blackberry before that too, never had problems with any SD cards until they've gone into this Photon Q.
Of course it'll be a royal pain to get it replaced as they'll walk in the backroom to examine it and see that the bootloader is unlocked, ah well such is life.

[Q] 128GB MicroSD support, problematic?

H2testw verified card (passed) caused my MT7-L09 to reboot spontaneously over and over again until I remove the MicroSD card. This started yesterday probably after I installed a few more apps. These have since been removed. Card has about 62.4GB out of 119GB, used 56.5GB. Formatted to exFAT on Windows 7. Working fine for about 2 weeks until yesterday.
I bit the bullet and hard reset the phone this morning. Clicked the MicroSD card back into the slot and loh and behold, it started to restart again!
Anyone have the same problem? Using a Sandisk SDXC-UHS-I card here. Its not hardware fault with the MicroSD card slot because replacing the 128GB card with a 64GB card presents no such problem.
Edit: Inserted the card into my Note 3. Card presented no problems at all.
Have u solved this problem yet? Im thinking of buying the 128gb sandisk ultra with the 48mbps read speed to be used in the Mate 7. Is this the same sandisk microsd card you are using?
I am proud owner of MT7-T10 who is having exactly the same problem after inserting newly purchased 64GB Sony UHS-I Class 10 microSDHC Card. In fact, I actually bought 2 of these type of sd - I have not tried replacing it with my wife's sd card - must do this test to flag out DOA (defective on arrival) sd card.
It was working just fine until the sd card is half full. I tried factory reset and reformatted the sd card and the issue reoccurs after transferring all my data back to sd card (i have not tried without removing sd card thou). Since the unit was still under warranty, I took initiative and brought the MT7 to Huawei service centre and even demonstrate the issue. They happily replaced with a new unit but even that had the same problem out of the box. I also asked if they have any list of compatible sd card supported on MT7. The front desk simply mentioned that it usually kingston, but there isn't any black & white papers or sites to support that statement.
I also came across forums emphasizing to use only popular branded sd card and sandisk was one of them. Since you are having the same problem even with sandisk, I won't be surprised if kingston too have this problem. Or may be it is MT7 sd slot defect by design. :fingers-crossed:
As overall, I'm happy with MT7. Extending the storage using sd card would have been a added advantage but this is not the case at the moment. :good:
No such problems on my Sandisk 128 GB Class 10 - had been using it on the phone for past 4 months

I did it twice but the problem persist.
i experienced that before, but in xperia and old s3. It happened due to runaway media-scanner process. somehow it kept running scan all the time from the start. It didn't cause bootloop / restart, but it literally hanged my phone that time
I'm not 100% sure but i read somewhere that Huawei recommended to use 32 gig capacity Max. Or you could experience bugs.
I have the same problem btw, with a Samsung Evo 64 gig...

They will tell you ; yeaah it supports 64/128gb card ..but they won't tell u it will do problems.. so in reality phones may be cannot manage larger sd than 32gb ?

Random unmounts and remounts of the SD card????

Just as the title says, I am having random unmounts and remounts of my sd card when trying to download things and when trying to view gallery. Phone is not rooted, its a sprint variant, and it's a 64 GB ultra sd card. I have had this card since my note 3 and it has given me no issues up until now. Am I the only one? Is there a fix for this? It's been doing this since day one.
Sounds like it could be a bad sd card. Try getting a adapter and putting it in your computer. If it reads it back everything up and format the card.
I've had a few micro sd cards crap out on me in the past.
I had the same problem. Never had a problem worth the cardin the previous phone. Format the card in the phone, still does it get a new card. And buy a Samsung micro sd. I have had numerous SanDisk cards die and finally went to Samsung and never had a problem since.

Forgot, not matter what, BACKUP YOUR DATA NOW off that sd card. So if it is going out, at least you will not lose any data.
Thanks all
