Micro SD card not detected

So today i brought a 8gb Transcend Class 6 mico sd card for my raphael. So i went back home and try it then i found it not detected on the file explorer but it says expansion slot in use when i go to Settings>About. Thanks in advance.

Transcend is not recomended by HTC. i am also having same problem with my SD card which is made by Transcend (4GB capacity). it detects when you put it in phone for a longer time, but you can not write/save/copy anything in it. it will say FILE CAN NOT COPY, MAKE SURE THE PHONE IS PROPERLY CONENCTED AND SOURCE FILE IS NOT MOVED BLA....BLA... BLA...
when i checked with HTC team, they advised me to use micro SD from SANDISK.

well the weird thing is when i insert the card on my friends phone(HTC TYTN 2) it detects it instantly after inserting it in. But when i insert it on my phone it doesn't work, btw i also tried another card from my friend, it a sandisk 4gb and it worked. hmm this seems top be a uncommon issue.

I ahve the SAME exact problem with the 8GB Transcend Class 6 Micro SD that I just bought for my phone. I've had no issues at all with the 4GB Transcend Class 6 card that I currently have. On the other hand, I had a 4GB Sandish Class 6 that would not work in my Raphael but would work just fine in my Kaiser.

Appearently the card worked randomly but i can't copy any file to the card for some reason.

look for something called SDformatter by panasonic i had similar troubles with a couple sd cards till i found this program.
they all work now in any phone/device.

Is there any specific setting to set in the program Panasonic formating program? Erase enable or whatever? I had my SD card working for about 2 or 3 days and now its not detected again.

I have similar my 8GB does not get recognized and if does it's only for a matter of minutes then corrupts but my 2GB reads fine, but the 8GB is fine in Kaiser already used the SDformatter to which makes it read till corrupts again within minutes...
Going to try some other cards out in local shop before purchase will take laptop to transfer data while there.

I have read in a lot of post that Transcend 8GB class 6 card have problems to be recognized by Rapahel.
I also have one. On my Kaiser worked well.
With stock rom it wasn't recognized by Raphael; with Energyrom it is recognized, but i used for few minutes, because i feared that something bad could happen..after reading all these post.
I usually use a Kingston 2gb card.
We were unlucky buying these cards...

Yes, I also have a Samsung 8GB class 6 card that my Touch Pro refuses to read. Tried an EnergyROM as I had read that for some reason they were better at reading some cards. But no dice - just bought Sandisk Class 2 and it works perfectly so far

Has anyone noticed problems with 8gb MicroSDHC specific

I've read quite a number of posts regarding problems cropping up on this phone with 8gb card specifically. All other capacity cards seem to be working well.
Is there anyone who's running an 8gb card flawlessly.
Thanks.

I'm running and A-Data 8Gb class 6 from ~ 3 weeks and I've got no problems at all

Good to hear Thanks.

I have a SanDisk 8Gb with no problems for 3 weeks, except once but I dont understood the real reason for that. I shuted down my netbook with the LG connected via USB cable in the "Mass storage only" mode and the card unexpectedly lost all data and the Android system ask from me to reformat the card...

Sandisk 8gb class 2 with no problems aside from the slow loading when I restart the phone since most of my apps are on the SD...

I got a 8Gb sdCard pre-installed on my P500 when I bought it. And it still works fine.

Well I tried a Verbatim 8gb Class 4 MicroSDHC and the phone hung the first time. And then it hung again. But nothing's happened in the last day except a random reboot....

Kingston 8Gb MicroSDHC works correctly from the beginning : LGP500 purchased since 11/15.

The issue (which I faced) has been solved in the latest firmware

which firmware version is that ? is it ok to go with 16gb card ? or should i safely choose 8gb class 4 card.

Kingston 8Gb Class 4 here with Noejn Javali R7 rom and no problems.

I have a Sandisk class 4 with Prime 1 and no probs at all!
Cheers

8GB microSD, noname, class 4 (tested). In my phone for 3 days, but has been used for several months in a Motorola Milestone before, so it's not brand new. No problems yet, on a void ROM with a2sd/d2sd module.

Mine is running a 8gb class 6 MicroSDHC without any problem on Megatron with a2sd/d2sd module...

I've tried Kingston 8GB class4 on my O1 v10a and it reboots every 2 or 3 hours...... sometimes it lost association with applications on the mSD and I've to reboot it manually....... Changed back to 4GB Transcend class 6 and all is working fine............
waiting for a firmware update.....

Running a 8GB Class 2 SanDisk MicroSDHC in my Optimus S, no problems.

Im using a class 4 16 gb sandisk.. No probs at all.

I got Kingston 8GB Class 4 (SDC4/8GB) 2 unmounts per day.

using sandisk 8gb class 2 with noejin's void rom... no problems!!!!

Kingston 8GB class 4 - I have aprox 2 unmounts per week. (stock rom, megatron, void, devoid, my own cooked rom derivated from stock)

[Q] Class 10 MicroSD Card, problem?

i did a test on Patriot Class 10 32GB Micro SD on my Sensation. everything went quite smooth, for 10 hrs...after that Sensation can't detect the card anymore. Put the card into card reader, PC can't detect card. so all data in the card was gone and the card is now rendered unusable!
tried on a Transcend Class 10 16GB, Sensation couldn't detect the card at all!
put in a Sandisk Class 4 8GB, Sensation immediately detected the card and i'm still happily using the card for 3 days without incident...
in fact, my Asus Transformer had the same issue with a Patriot class 10 32GB card. wiped the data on the card and rendered it useless...
so any info that i should know abt regarding class 10 MicroSD Card?
thx

I have no solution for you..
I can only say that i am using a Transcend Class 10 16GB card
with no problem. Maybe the problem lies within your phone?

but it happens to my HD2, Asus Transformer and my Sensation...
three devices with the same problem?
i really dunno...

If the card couldn't be read by your pc or 3 other phones, that would lead me to believe that your card is bad. Hopefully you bought it from a reputable seller with a solid return policy and you can just try a new one.

Ive had this problem a few times, its usually the card. I was able to detect mine using Micro SD Adapter but i couldnt open it up. I used Paragon Partition Manager (only thing that detected it) did a full wipe (takes a longgg time 5-7 hours) and then reformatted using windows to just a FAT32, then used Clockwork recovery to partition EXT. It worked fine after that, it was my old 8gb card

I've bought a 16GB Class 10 microSD from Patriot. No problems at all. works fine and is very fast.
Your card must be broken...

Transcend 16GB SDHC Class 10 card

Bought a Kingston 16GB SDHC Class 10 card for my Desire a while ago, and found out it is not a happy match. Simply too unreliable. Went back to the good ol' trusted Transcend 8GB SDHC Class 6 card.
Anyone got any experience with the Transcend 16GB SDHC Class 10 card on the Desire?

Hi,
I have a Kignston µSDHC 16Go class 10 and I'm very happy with it. What do you mean with "unreliable ?"

My device was becoming noticably slower with this card instead of faster, and I got read errors continuously in apps like media players, Astro File Explorer en Root Explorer. Possibly it was becoming slower because of the read errors.
A chkdisk on Windows 7 continuously gave errors and a chkdsk on EXT4 Recovery sometimes was even unable to fix errors on it.
Reformatting only helped for a short while, then the read errors would reoccur.
So I finally gave up on it and trashed it.
I read everywhere that the Desire is very picky when it comes to memory cards.

Well, it seems like your kingston card was dead, it shouldn't give any error on a chkdsk.
Did you know you can get it exchanged from Kingston under warranty ? It has a lifetime warranty. I had to do it for mine because the first one I had was defective from the beginning, I couldn't format it at all.
Trust me, I have this card and it works flawlessly since I got it exchanged !

I did exchange it already, the 1st one truly was crap, far worse than the 2nd one, the 2nd one was slightly better but still crap. So I decided to ditch Kingston altogether.

Lexar cards
I've had good luck with a lexar class 10 32gb cards. No one I know has any transcend cards though.

I can't use Transcend micro SDHC 16 GB class 4- I had to pull the battery almost always after using an app that accessed SD (camera, gallery, music player etc)

I've found that samsung has been a dream with good speeds and no issues (as of yet...). As for the Kingston i got a class 4 card and that worked fine for me.

Moto G 4g LTE - Sandisk ultra 32gb microsd card won't mount

I picked up the Moto G 4g LTE version recently hopping on the fact that they added an sd card slot. Anyway, I purchased this http://www.amazon.com/SanDisk-Ultra-MicroSDHC-Memory-Adapter/dp/B007XZM6VG/
microsd card hoping for some nice expansion. But for some reason whenever I insert it it says damaged sd card, tries to format it, then says blank sd card, and basically loops this process. Now here's the weird thing, this sd card works fine (can read and write) in other people's phones, but just doesnt seem to work in mine!
I even tried my friends 32 gb microsd card and it worked (it was a slower class 6 varient),I tried *my* sd card in that persons phone, and it mounted and worked fine, the sd card works in my PC also.
I'm wondering if I need a slower speed card? Maybe class 6 or 4. Because I read up on another guys problem on here, his is freezing but he got a slower 32 gig card and now it works without a problem. I know he was having a different problem but I'm wondering if the phone is having an issue with class 10 cards.
Anyone having the same problem or have any idea what might be going on?

Hi,
As I mentioned on the "other guy"'s topic, I experienced this kind of issues with my previous phone, which were entirely solved by replacing my 32 GB Sandisk class 10 card with a 16 GB Samsung class 6 card. AFAIK, fast cards may cause malfunctions with some Android phones, because of the access response times.

Had the same issue. resolved by getting a different brand and lower class. all issues resolved.

I'm using this card bought thru Amazon for 17.99 ------Samsung Electronics 32GB EVO Micro SDHC with Adapter Upto 48MB/s Class 10 Memory Card (MB-MP32DA/AM)------
I have had 0 problems with it and high benchmarks, I use to use Sandisk but after multiple problems with multiple cards over they years I have completely abandoned them for Samsung and have yet to have a problem.

The problem comes from that, some cards won't fall back to lower performance level and thus causing issues for the device that it is inserted in.
Some devices does not have problem with that tough.
Another reason could be the file system used, but that's less likely, although not very rare.
And one more thing is that brands like SanDisk, Samsung, Kingston etc are the actual developers of the SD technologies and sometimes you may get a product that is using newer technologies, which often causes troubles.

I purchased same Sandisk micro card from Amazon as OP did. I got same results. It is sitting here on my bed with RMA on it to back to Sandisk. Just got a new speck sheet which was posted from the motorola forms that says the following:
Micro SD UHS-1 "The card will work, BUT the Moto G 4F/Lte WILL NOT SUPPORT UHS 1 - SPEEDS.
So it appears, a slower speed card is in order. I just had to purchase a Samsung 16 gb class 6 card. Would rather have had a 32 gb but could not find in class 6.

Random and Sequential of my 32gb Samsung Evo UHS-1 in my Moto G LTE using A1 SD Bench

Thanks so much for the input and advice guys! I was too impatient to order another sd card and wait for it to ship so I went and bought a random 32 gig class 10 card from a brand i've never heard of called "Monster digital" and it works perfectly. So I'm not sure what really fixes it, if it's a brand thing or size or speed or what. But my change from my non working sd card was Speed: UHS-1 -> Class 10, and Brand: Sandisk -> Monster Digital

Regarding the SD card issue. I tried with three separate phones with a 32gb class 10 and and a 16gb class 4 -- failed on two of them, but works fine on one of the phones. So there is definitely a build quality issue ( and/or difference ) between the phones, aside from the mentioned 'supported sd card class.' Both of these cards work fine on all other devices ( pc/laptop/tablets including old SD card readers with adapters )

Wanted to give an update. Tested with four devices now ( 2 black, 2 white ) and First one ( white ) worked, next two did not work, but the fourth device ( black ) it worked to detect 32gb sandisk without fail. So there is _definitely_ a difference between them from device to device -- maybe even assembly line quality control issues depending on week of manufacture, who knows.

Very interesting (and puzzling). Do they all run exactly the same version of Android? Are they all exactly the same model (eg. XT1032) and the same internal storage capacity (8/16 GB)?

Oops, Moto G LTE is 8 GB only, sorry.

Yes.. exact same model/capacity and OS, all ordered within the same 1 week period ( two being RMA )

Can verify that the XT1045 4G LTE performs very well with a 64GB SDCard inserted internally, ALSO..with a 32GB MicroSD card inserted into the USB / Charge port..and runs both very well, and with both cards mounted..

I have a Moto G LTE on order, and am wondering if the various problems people are seeing are due to the file system used on the card: exFAT or FAT32. I would assume the newer SanDisk cards are formatted with exFAT. Does the flavor of Android on the phone support exFAT ?
Another issue I've found in the past with some other devices and ROM's is that if the card is formatted as exFAT, it might need be set up as a primary partition and not a logical drive (using MiniTool or some such).
But we'll see what happens when the phone & card actually arrive

As far as I'm concerned, my cards were all FAT32-formatted, both the malfunctioning SanDisk and the Samsung that worked well. Nothing to do with exFAT vs. FAT32 then.

Exact same 2 cards ( check my previous post ) , tested on 4 (four) MOTO G LTE , 2 Samsung and a Camera and a Tablet worked only on 2 of the MOTO G LTE's + all the other non motorola devices. It cannot be the formatting or even the make of the card if it's a compatiblity issue.

DId not work with same Samsung microSD

I am getting 'Removed SD card' / 'SD card removed, Insert a new one' error by using exact same Samsung 32GB EVO Micro SDHC. I could not format it by using Moto, so I did a full format in my PC, Same result. The microSD symbol is UHS-1 (one capital U with '1' inside') - matched Amazon's picture.

Try a slower card (class 6 fort instance).

My XT1045 and sandisk ultra 32gb card both arrived, and they seem to work together just fine. Android version is 4.4.3. Card came formatted as fat32. Promptly unlocked the bootloader in hopes of flashing slimkat at some point

Just got my moto G 4g delivered today and My 32gb Sandisk Ultra (which I had for 2 years in 6 different phones) won't work. looked it up, saw this thread and I'm kinda sad that I have to buy a new sd card for this when I paid a premium to have the ability to use a sd card in the first place. Nonetheless, I'll take the safer route you guys talked about and try for a lower class speed. Just ordered a samsung 32gb (not the evo model) class 6 from amazon for about 19.25 after tax. it should be here on the 25th I'll let you guys know if it's a good one to use. I knew kit kat didn't play nice with sd cards but this is ridiculous.
