[Q] SD Cards Burning Out

I have an unlocked Rogers Samsung Captivate Glide (i927R) running gingerbread (since Kies doesn't want to update it to ICS, and I haven't gotten around to rooting it), and it seems to be eating through SD cards. I had a 32gb micro SD card in there, but the phone decided to stop reading it after about a month and a half. Nothing else can read the card either; not my computer, not another phone, not even my camera can read the card. This is the second 32gb card it's happened to, and I'm starting to think that maybe it's my phone. When I have the card in the phone, it simply says "Unavailable" when I check under storage, although the phone can still read other SD cards.
Does anyone else have problems with this phone (i927R) killing SD cards? Am I simply just overloading the SD card, or is there some possibility that the phone is burning them out? Should I go for a 16gb card and see if it doesn't burn out, since smaller cards seem less likely to burn out?
Any help is appreciated.

The last one that burned out was a Transcend, and I don't remember what the first one was. but I don't think it was a particularly high quality brand. I will be sure to get a better quality card next time.
Do you think downsizing to a 16gb card would reduce the chances of a burnout?

It's a crapshoot man ... I've had kingstons bad out of the box at a couple of sizes, the flash drives I had die were 16gb Corsair USB3's and rated with high speed..
just make sure you get a class 10 and read up on some reviews ... Newegg is really great for it, lookup the brand, price etc. and then to buy it at a local store and have them price match...
I should really get in the habit of backing up all the information on my phone more than once i run out of space
*EDIT* .. The current one I use is G.Skill 32GB .. Lifetime Warranty. Comes w/ full size SD adapter.

Anyone else with µSD card disconnection issues?

Hi All,
I got my Xperia ZL some 3 weeks ago, and since I'm still within my return period, I wanted to see if anyone else is having problems with frequent µSD card disconnects - to get a feeling for whether this is a firmware issue (correctable via upgrade) or I have a dud.
I have been fairly unsuccessful in getting my music synchronized with iTunes on my Mac. Although part of the problem is the horrors of the Sony Media Bridge application, the real issue is that my memory card keeps disconnecting while files are written to it! It reconnects a second later, but then Android keeps "Checking for errors" for some time before it becomes available again. Meanwhile, the synchronization stops.
I've also tried TuneSync from the Android store, with similar results. This application lets you synchronize in two ways: via Wi-Fi or by mounting the memory card to your computer (either using Mass Storage mode on the phone, or by physically removing it and using a memory card reader). WiFi sync always fails for the reason above, as does syncing in Mass Storage mode. If syncing via a memory card reader, the sync completes, but then there are all kinds of issues when reinserting the card into my phone, while TuneSync is processing the wired sync data.
My card is a SANDisk 64GB class 10, but I've also tried a SANDisk 32GB class 6 card with similar results.
Let me know if you have seen anything smilar - and better yet - if you have managed to get around it somehow.
Failing that, I'll probably return this phone in favor of a HTC One... (I prefer the ZL, but not if it's not working!)

Have the same problem. Read somewhere that there are problem with SanDisk ultra cards.

I've used the same card in my Nokia 808 PureView (Symbian) for nearly a year without any such issues... So there is obviously something specific to the Xperia and/or Android that does not jive with these cards.
Also, my other card (the 32GB class 6 one), although SANDisk, is not "SANDisk Ultra".
Good pointer though! I'll try to dig up some cards from other brands to have a go!
Thank you! :good:

This is interesting. I've now seen 2 dead Patriot memory cards in my husband's ZL ... switched to a Kingston card in that phone now & will see if the problem continues. I'm currently using a Samsung 32gb card in my own ZL and haven't had any problems (I've had the phone for a few weeks).

No issues here
I've been using my sandisk 64 gb microSD (Class 10) on my ZL without any issues for over a month. Before, I had used it on my note2 for 5 months with no issues. Its strange many people are having issues with sandisk cards. But, I can tell u that its not an issue specific to Z/ZL, it's rampant across the recent Samsung phones too (note2/GS3)! I guess it must be a bad batch of cards by sandisk or something. Btw, I'm on rooted stock rom with locked BL & only formatted my sdcard once using phone (ZL) before using it. I also have a 32gb sandisk (class10) & 16gb sandisk (class 4) microSD cards working just fine on my other devices.

This is not problem with the phone, The SD card itself have got a problem with major smart phones. better keep your ZL

SD card unexpectedly removed.

Anyone else getting this message? I put in my 64gb SanDisk Ultra and have been getting it intermittently since day 1. Almost always when I open camera or gallery. I reseated the card, took everything off, formatted and everything to no avail.

samsung and SanDisk 64 gig cards are an awful mix. my s4 killed my 64 gig card and I got it replaced. new one worked fine... didn't use it for a while bc i had the g2, but i used it in my digital camera and it was perfect. then I got the galaxy tab s in July and put it in there... by October, the card is dying again. keeps randomly unmounting and stuff. it's a Samsung and SanDisk issue. I have a 32 gig SanDisk class 6 that works fine and never corrupts but the 64 gig class 10 always corrupts. people have this issue often. I'm actually gonna buy a Samsung 64 gig card as many people did that and they say it doesn't corrupt like the SanDisk does.

Me too. I had my Scandisk 64 gig card in my note 2 for 2 years no issue. As soon as I got my note 4, I have been having this problem randomly. Seems to be happening less as time goes by.

I used to get that with my note 2. Supposedly it's a loose cable connector. If I placed my phone on the table, the force of the placement would cause my phone to say that. I really hope my new phone won't develop this over time. Maybe you can try to test it by slapping it into your hand (that used to trigger it in my n2) btw it's not specific to the card manufacturer because I had the SanDisk 64 class ten and now have the Samsung 64 class ten and they both did it in my old phone. You should try to see if you can get a replacement if you can replicate it in the store.

The same thing has been happening to me. I have had a 64GB SanDisk Ultra card since the Note 2 and it hasn't caused any problems. Now with the Note 4 is is doing this all the time. I have formatted it with the Note 4, reseated it, and it still is happening. I hope they can fix it and soon.

Also, btw it was not specific to a firmware/software/kernel because my N2 had many many versions of touchwiz, android, and cm on it and they all did it.

I used this card on my note 2 and note 3. It still works fine in my note 3. I took everything off and formatted it on the note 4 itself. I then left it blank and didn't get the issue. However as soon as I take a picture, try to send one via mms, or play music(I downloaded a song to sdcard), I get the error. It almost seems as if everytime it tries to access anything on SD card it happens. I'm going to take it in and see what they have to say about it. I'm sure they will tell me it's my sdcard. Even of they replace is what are the chances it will do the same thing? My cousin has AT&T model and his does the same thing.

Ultra Class 10

I'm getting this same issue with a 64GB SanDisk Ultra Class 10 MicroSDXC card. I was about to RMA the card when I found this thread. I hope a solution is found soon, this drives me crazy when trying to take photos.

Yes! I have a 32GB Sandisk Ultra that seems to get lost on a daily basis...
Also, not sure if this is the case, but I seem to remember this was an Android 4.4.4 issue?? Or was it KitKat??

Same issue here. I yanked the SanDisc 64GB Ultra from my Note 3 when I sold it. I put it in my brand new Note 4, and it would get that error constantly. I removed it, formatted it, put it back in, formatted it again via my phone, and then transferred over some videos. I could play them a bit but it would quickly lose the memory card and stop playing. I yanked the 32gb from my GoPro ,formatted that, and it's been flawless ever since.
I wish I had an answer too. I got this phone partially because I like having a lot of storage space available.

I had the exact same issue with a SanDisk 64gb card. Thankfully I had purchased a Sony micro SD card not too long ago. Put it in and haven't had any more problems. Very strange that it seems to only be SanDisk cards having an issue.

My Scandisk 64 gig was solid in my note 2 for 2 years. In my note 4 it does it like every minute or so.
Put it back in my n2, rock solid. It is not the card. Now here is the weird thing, I took off the back cover and rock solid. If you look at the inside of the cover the is a little bump I think to help secure the card. I think that is the issue.
Try to perform some stuff on the card with the cover off. Let's see if it really is this simple. Report back with your findings. I am interested to know.

When I was first having issues with the card, I got sick of removing the back, and left it off. I still had problems.

I have had zero issues with my card. Again. It is not a SanDisk error.. it is model specific. When getting the note 4 I went with an SD card that is 4k data compatible. Yes.. ordinary memory cards will not like 4k data. Is that why yall are getting errors? I'm not sure but it might have something to do with it. That a data transfer rate must be able to handle the pics and videos we create with this high end device.
I have this one...but in the 64gb varient.

Again, absolutely zero issues since I've loaded the card into the phone.

200 gb SanDisk Card $99

Has anyone tried a 200gb in the Zenfone 2 yet? Amazon has them for $99 today.
http://goo.gl/JnD5kC
Dan

since its sdxc it should work.

If Amazon only has them for today or a limited time, Newegg seems to have them for 99 as well. Though the speed class might make writes a bit wimpy.. Perhaps the 200GB could hopefully be an underprovisioned 256?

No guarantee from Asus however.
I remember when I had to spend $75+ for a 32GB for my Nook Color

They'll work... AS long as SDXC compliant...

thats cheap

I have a sansdisk 128GB micro sd card and it works fine so you're good

If someone does get the card, and tests it with marshmallows adaptable memory, let us know how it works out!

Wow I really need this

They had the 128gb PNC cards for $30 a few days ago. I grabbed one and it works great as well .

I once had problem with sandisk too, it gets randomly dismounted then mounted again and that's not from restarting. It also happened to my wife's zenfone 2 550 and zenfone laser until she finally decided to replace it with samsung like what i did.
Idk whether this problem exist in every zenfone 2 and other zenfone released after, but grats if some of you didn't experience the problem, but if i were you i won't risk it by buying cheap sandisk. There once an update (i forgot, between 150ish-168 on 551) that address sdcard issue, but I haven't tried putting in sandisk again after it.

Any one ever tried the 200GB card ?

@Ashtrix ... in my ZE551ML the SDSDQUAN-200G-G4A works for more than 3 months with no problems

HUGE Micro SD Cards

First do yourself a favor and tape your micro SD card to the phone with a little piece of Scotch tape. I received the 200GB SanDisk Ultra for free when I purchased the V10 and unfortunately while swapping batteries in the dark the Micro SD card came loose and fell out. Huge bummer given the cost.
Spilled milk aside I've decided to replace it with a Samsung Evo Plus 256 GB micro SD (true usable 238). They can be had on ebay for about $70-90. The 200 GB SanDisk Ultra is about the same. Crazy because these things were nearly $200 early in 2015. I happened to have 64 GB Samsung Pro but quickly filled it up with my YouTube Red subscription and Google Play movies and surprisingly there weren't as many videos as I thought would fit. So I figure go for the big Kahuna.
I decided on Samsung after reading that they had had a better track record with stability than SanDisk.
Anyone else using the 256 Samsung how good is 95mb/s for a power user phone like this? Is there lag? There seems to be a great deal of variance in performance for micro SD which does not entirely square with price.

I am pretty sure most Note 7 users have 256s.... Me & My wife have them installed. Haven't run test. It works... Holds all my pics, movies and roms.

95 (MB) OR (Mb)/s. Huge difference. And I don't know of any phone that will do the rated MB. I usually get 12-25MB out of my 128/200GB cards, usually around 15ish. That translates to about 96Mb-160Mb/s. The new UFS cards Samsung started talking about will probably get close to SATA3 speeds which amounts to around 500MB/s, which in real life will probably mean a out 3-400MB/s and I am being optimistic. Nonetheless when phones start coming out with UFS micro slots they should be as snappy as internal storage, mostly. Random IOPS will probably be a lot better but less than 100MB/s I would guess.
And I am talking about phones. Rated speeds will usually be about 20-50% of advertised speed. Closer to 80% or so in a computer. OEM's tend not put the best hardware for micro SD cards in phones. I would guess because of real estate and possibly heat and battery. Nonetheless, I hadn't planned on buying the V20 but the multimedia capabilites were too hard to pass up and my final cost after promotions and a couple of phone sales will probably be less than $400. If I include amps and DACs closer to $200. My next phone will have UFS for micro slot. No doubt.

Won't UFS come at a much higher cost premium and will the practical speed improvement for phone storage really justify the cost if the prices for these huge capacity micro SD's are collapsing?

ebay... microsdcard.... "remembering buying memorystick and it was fake"... -_-

Just ran a benchmark on my Samsung Evo plus 256. Got 80 MB/s read, 40 write.
Sent from my LG-LS997 using Tapatalk

The new microSDs are rated pretty fast. 90mb/s both read and write
I'm just uncertain if the v20 is able to make use of these speeds.
ie. is the v20 the bottle neck?

If I remember, seeing that UHS 3 cards have two rows of pins on them for faster transfer speeds, but I don't believe any phone supports that second row of pins yet.

Oh yea i forgot to mention that i almost had a similar incident you had. Upon recalling my note 7 I put my memory card in that plastic casting and in my pocket.... somehow the memcard slip out and out of my pocket.. Luckily after searching around I call best buy and ask my old coworkers if they see any memcard around and they did =D... it be bad if they didn't.....

Maybe ill lost this here as I didnt get much feedback in the questions section. I have a 128 gb SDXC micro sd that worked fine on my v10 but isnt even showing up as a option on my v20 . the settings app only shows internal storage. I really dont want to format it but guess might have to . but I have a lot of files on there and don't want to transfer them as even deleted on a computer they still leave a trace

Was that sd card encrypted on the V10? If it was you can only read on the device you encrypted with.

Yeah the reason you see those cards for that cheap is because Samsung flooded the market with 256gb cards with the Note 7 and then S7/Edge promo where they gave them for free. I have 2(one in my V20) and am selling my second one (hopefully today) for $80

LG figured rather than offer another free 200 GB SanDisk card the V20 buyers can buy all those Samsung 256 GB cards flooding Ebay and sell the B&O headphones to offset. Thanks Samsung!

All micro sd cards are compatible with the V20.

I can confirm that V20 can't read micro SD UFS-1. I bought Samsung 128GB micro SD EVO+ and Kingston 128GB micro SD UFS-1, but both can't be detected by V20. I feel very strange and confirm that these two card can be read by V10.

Wrong! These two cards are brand new and can be used on PC ,V10 or my wife"s Samsung Note 3. Unfortunately, my V20 can't support them.
