[Q] Troubleshooting- Problem with 2 new 8GB SD cards

Hi guys,
Im running CM 7 on my HTC desire with Go launcher and just upgraded to a new class 4 8gb SD card made by Sandisk.
I got the first one last week and it worked fine for 12 hours, until i started getting force closes and soon enough, the screen turned blank and only the home key buttons lit up at the bottom. I had to do a battery removal restart and the notoification bar said " Preparing SD card". This never went away even after restarting. I then requested the retailer to send me a new card as i thought this one was corrupted. He agreed.
I used my old 2gb card for five days and did not have a problem.
I got the new 8gb card again yesterday and BOOM! 12-14 hours later, im facing the same problem. I ve had to format it through recovery and download everything again. It still hangs, screen blanks out and i have to do a battery removal restart and all my apps have gone. In the settings menu under "manage applications" they only appear as com.appname.xyz and a grey icon
Here is exactly what im doing-
I put the new card in my phone ( without formatting or partitioning) and download the applicatiosn i need from the market. NOTHING ELSE.
Can anyone help me here? Is there something im missing out? Im fed up of restarting my phone every ten minutes and not having any applications.
Thanks

Moving to Q&A

Did you buy it off ebay?

Well not exactly Ebay but the indian version called Flipkart.
The card sells for around a discount of 50%.. I now understand why.
Do you think this could be a faulty batch of SD cards?

*sigh*... you buy from a market which sells things at 50% less.... was it REALLY that hard to find out you just got ripped off for fake sd-cards... seriously buy from somewhere reputable.

ok, let me correct myself. Its the Indian equivalent of Amazon. They have a full return policy which i used to return the first faulty 8GB card and continued to face problems with the new replacement. They have offered to take this card back as well and credited the money to my account five minutes ago..My point is all this is a big hassle for something as silly as a card..
My query is still, what could the problem be? DO HTC Desire's have a problem running 8Gb SD cards? This is a class 4 card...
Anything i should be doing before using a new card?

Okay, so that's not so bad then. As far as I know they don't, before I was using an 8gb Class 6 sandisk, then a 16gb class 6 sandisk and they're fine..
Try buying from somewhere else though, maybe it WAS the seller

External SD card disappeared...

So I woke up this morning, phone says SD card unplugged, please insert new...knowing that I obviously did not remove my external sd card I then proceed to check
Settings, Storage --> (nothing shows up)
Boot into recovery --> can't mount external SD card
plug it into PC --> nothing shows up
So now the question is, do I have a bad/dead micro SD card or else?
I am on CM10 which is updated nightly, that might have something to do with the SD card, I dont know.

Edit-- missed where you said you already tried directly from computer.
Might just be a dead card.

Unless it is just not being assigned a drive letter on the pc, the card is toast. If you are using windows you can got to the disk management snap in from the administrative tools and see if it is listed at all, if it doesn't show there it is fubar. Easiest way to get there is right click computer, manage, disk management. For linux or mac im sure there is a similar tool but i couldn't tell how to get there or use it.

Which recovery do you have? Same thing happened to me on 6.0.1.4 Touch. Computer still saw the card, so i pulled everything off the card, reformatted with the computer, then changed recovery. Phone saw it after that and no more problems since.

Thats just the nature of flash memory, eventually it does go bad and unlike mechanical drives which often give plenty of warning of impending failure flash rarely does. Granted 2 months is obviously not acceptable it could be just a freak thing or maybe just an inferior brand. It is also highly susceptible to static discharge, especially in a SD card type format where the pins are exposed. Although possible, i doubt a static shock happened inside the phone but it could have possibly been damaged and just took a while to completely fail.

I used this to format my 64gig chip

Get a new card...i would also check on any warranty offered by the manufacturer, that goes for OP too. Depending on the brand there may be a 1 year or even lifetime warranty, some of the lesser brands might not have a warranty at all. Although i haven't followed my own advice in this category as the last 2 16 GB micro SD's i've purchased have been fairly cheap class 10's, you more often than not get what you pay for. I would also recommend going for the class 10 cards, not only do they have the fastest transfer speeds (and maybe because of this) they seem to be more reliable then their slower cousins.

Although i've never had one of their SD's, Kingston is one of the top tier memory companies and carry lifetime warranties on most (if not all) of their products. At the very least i would expect a year.

In my experience SanDisk is considered a cheapo brand but they have been around long enough to have overcome that reputation. I would imagine they also have a warranty program although i can't speak from personal experience, definitely worth checking into.

Im quite sure that my kingstone sd card is genuine..
Any possibilities that my S3 killed it?

I don't think SanDisk is a cheapo brand since they have been making great cards for a long time. They have a great warranty program. They will replace anything within a year for sure. I had one that you couldn't read the serial number on so they still replaced it.
SanDisk has a problem by being the most well known microsd, they are faked by chinese companies all the time and those fakes look just like the real ones. Therefore, you buy a fake, paying real prices, that looks real, and you blame SanDisk. I think that was what happened in my experience with a dead card, and they still replaced it.

You can't just format it from "My Computer". You will have to go into device manager and find it, then format it that way. Otherwise it will not work.

UPDATE (see post#30):SanDisk Ultra 32GB kiss of death? (

For the past 4-5 months, I've been seeing quite a few posts regarding issues with the SanDisk Ultra 32 GB microSDHC Class 10 UHS-1 Memory Card 30MB/s with Adapter SDSDQUA-032G-U46. I bought one back in November 2012... been running it hard for 6 months without incident.. so figured I was one of the lucky SanDisk recipients.... until today! Starting today, every time I wake the phone get the "sdcard mount" message. So loaded "SD Card Monitor" from the Market (screenshot attached) and found that during deep-sleep, it unmounts/mounts/removed/bad-removal/ejects constantly (example: phone slept from 10:04am to 10:22am)...but during wake state, no issues. So I suspect I'm about to experience the SanDisk 32GB Ultra kiss of death any day now. Backed up ExtSD to computer, but now the search for a proper extSD replacement. Any recommendations? Leaning towards Samsung 32GB or 64GB...
UPDATE: SEE POST # 30

Yea I just bought mine about a month and a half go. One month in of using it, my card corrupted and I ended up having to reset it. Lost everything! Lucky I put anything of importance on my cloud before it finally died on me. :banghead:

Are you having issues with dropped calls too? I was thinking I was alone, and maybe it was a bad module? I got my phone 2nd hand, and that's my next step to order a new sdcard/sim card module and try to replace it. Data works fine and never cuts out, phone calls last maybe 30 seconds, and it's killed 2sdcards already. ..

No problem with dropped calls... can still read/write to extSD fine, but now getting all the mount/unmount warning messages (and log confirms its poised for failure).

FAT32... not a single problem for 5 months until today... and I r/w the crap out of my extsd cards daily... we'll see what happens.. still works, just getting these warning messages.

Really like that Samsung SD card idea.
Back to Amazon. ...g

I purchased one of these from Amazon last week. Works like a charm, albeit only when formatted as FAT32.
It is roughly twice as fast doing read/writes than my previous Samsung 32GB card.

My Sandisk stoped working also, so I bought the samsung 32gb and it's starting to do the same thing again. I just think there is something wrong with samsung phones in general.

I haven't had any issues with my sd card or phone. But a buddy of mine has burned up 3 pny cards and one sandisk. Although it's an s3. Sounds like a phone issue. I told him to call a warranty claim.

[Q] Bad 32gb micro? ...or did I F up?

Im not a stranger to rooting (thanks due to all the awesome devs here!) But sadly a ran low on storage. Bought a 32gb Sandisk class 10 ($24...Why pass on that?!) I copied current sd to computer, then transferred to new sd card. Well, phone was incredibly laggy. Ended up freezing. Pulled battery, rebooted.... froze on samsung screen (waited almost 10 mins) Pulled battery again. Attempted to reflash current rom, but upon reboot it sent me back to recovery with message of no OS. Not one of my roms would succeed. Back to old sd card.
Now i must ask, did i miss something here? Or is it a defective card? Im a sucker for punishment. I formatted card, only putting rom files on to use. Still failed on me.
Returned to original sd card, reflashed rom. Back to normal!!

There is a known issue with SanDisk SD Cards, and the Samsung Galaxy S3. You can find more info HERE. I believe the the issue has since been resolved. You can try to format the SD Card with SD Formatter. It may save the SD Card. But either way you can follow the link I gave you. There is another link there to the SanDisk site. They should replace your card. Or you can take it to your local retailer with a copy of the link page. They should take care of the issue.

HTC 10 damaged micro SD card

HTC 10 damaged my micro SD card. Did happen to anyone else?
I listened music form my phone on my way to work in the morning and then, on way back home firstly music didn't play, so I found that card is not recognized by the system even after restart. I have checked it later on two computers with 2 different adapters and no appliance can recognize the card. Branded 64 GB Lexar fast card. HTC wasn't restarted or so, wasn't even hot I kept in whole day in the pocket. I'm not sure what to do, I mean don't want to lose another memory card which I probably buy.
And maybe, by any chance, someone have any idea how to check memory card whether is completely dead?

It's more likely a short life span micro sd card, and this kind of suck always happen once a while.
Don't blame your phone unless other one or two micro sd cards also die in the first two weeks.

Hi, The reason I'm asking is to avoid the risk in the future. If it happens to anybody else I will rather buy some cheaper card.
That memory card was bought for GoPro so I use it for many other apliances without any problem and suddenly it broke with HTC 10. At least I noted it here for statistics.

Cards fail. Cheap cards fail often.
Lesson, buy more than one card and don't recycle them from device to deice.
Another lesson, don't ever buy cheap cards.

The HTC 10 does appear to be finicky with microSD cards. My 128GB Sandisk that worked totally fine on a Galaxy S5 kept giving me problems on the HTC 10. I wonder if the phone is stressing the cards too much somehow (for instance if it is scanning the card too often for media files and you happen to have tons of media content on the card like in my case).

Thank guys for the reply,
I never broke before any memory card and that one was not cheap. Happily I can buy now double capacity and double speed for half of the price which I spend for the last one. I'm planning to buy Lexar 128GB. That card did work perfectly but only few days.

I'm having issues with my card as well. I purchased the SanDisk Ultra 200GB Micro SD from amazon. I put it straight into the phone and ran diagnostics on it to confirm it was a true SanDisk card and its read/write speeds which were in line with manufacturer's specs (88 read/ 14 write). Within the day it was having issues pulling images off the card. All the images saved directly to the card had a grey area or "box" over some portion of the photo that would correct after a few seconds leaving the full picture to view. The images could be sent with no problem but eventually they seemed to become corrupted. I figured it was the slow write speed causing the issue so I replaced it with a new Samsung ProPlus 128GB card (95 read/ 90 write) and the issue still persists. Not sure if anyone else is seeing anything similar.

if your looking for a new one, this one is great. very fast speeds 90mb write 95mb read. bit on the spendy side so hopefuly it was just the card failing and not the HTC 10 eating them
I haven't had any issues with 1000s of files on mine so far, crossing fingers

Same here, Kingston 128 GB micro SD worked fine on my s7 edge. Inserted the same card in my HTC 10 and it was readable for the first hour, after that the card was not recognised by the device. The card wasn't even recognised by my Mac and PC. I'm glad I had my photos backed up on google photos.

My 64gb kingston kicked the bucket in my HTC 10. Last weekend I woke my phone up and it said sd card unexpectedly removed. Card was not readable in any other device.
Got a Sandisk as a replacement as never had an issue with their cards in the past. The kingston only lasted 4 weeks, but I'm putting it down to just a faulty card.
If the sandisk dies too, then I'll be a bit concerned it could be the phone...

Im Using Lexar Pro SDCARD 128gb and havent had issues using it. The card was also formatted as adaptive.

So, there is two of us. There is one only connection - 64gb.
Where is Sherlock?
by [email protected]

You're made me worry. I use SanDisk 200 Gb, it's kinda expensive one.

Worry for what?
I don't have any issues with my HTC10, but I broke a 64gb Sandsik in my Sony X10i, phone just got hot. Shut down, Card didn't work anymore. And another one SanDisk 128gb was in my Sony Z2 when I replaced the back plate somehow the MicroSD got broken.
The 64gb Card had a Lifetime Warranty and the 128gb a 10 year. Not sure how long my 200gb card is now. Think they reduced it to 3years or 5.
But yeah, went to their Homepage, registered the cards. Requested replacement, they sent someone here to pick them up, 5-9days later I got the new Cards via Mail
So yeah, always back Up your important stuff somewhere else and who cares if they fail. It's annoying Yes, but **** happens.

SD cards can fail in ANY device. I wouldn't go as far as saying it failed because of the device. Quality of the cards is what really dictates how soon failing can occur. A knockoff SanDisk failed in a few months while the real one has lasted years for me. I highly recommend SanDisk and Samsung SD cards because I have had no issues with their original products.
EBay and some Amazon sellers have tendencies to sell fake cards so beware.

I woke up this morning and my HTC 10 says that the micro card couldn't be recognized. Crap. Did a search and found this thread. The card is a Lexar 64gb card. I went to Walmart this afternoon and got a Samsung 128gb card. Hoping this card will last my long tern stress test. Ha!

if your looking for a new one, this one is great. very fast speeds 90mb write 95mb read. bit on the spendy side so hopefuly it was just the card failing and not the HTC 10 eating them
I haven't had any issues with 1000s of files on mine so far, crossing fingers

been using this without any problem 128gb and prior to this i tried samsung evo + 128 and that worked fine....
but as the OP stated it is true that many users using diferent sd cards has been facing issues with htc 10.....
some has issues on some firmware, some on custom kernels, some on different formats so its wise to say that there is something beyond a faulty sd card itself.
in all the custom rom threads you could see sd card issues highlighted at one point or other by mutliple users including devs

I have the same issue, and now i remember this is the second one in my htc 10, first one a pny 128gb worked well for more than one year in my previos s5 and after a month in my htc it failed, i blame the sd card that day and decide to buy an 128gb lexar and today after 5 months it failed, or i have a very bad luck now or my htc is damaging my sd cards.
