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)

Well, I have two microSD's.
1- Fake microSDHC & unknown class 8GB, : > worked only cotulla's system but too slow (the newer devs version doesn't work) it needed two hours for first boot, and the second time half hour. the newer devs versions will add about ~20MB Data and will stop. but cotulla's continues to complete the process witch means android boots and works, but slow.
2- Genuine, Transcend Class 10 8GB, : > Very Perfect! too Fast speed!, powerful... needs about ~1 minute or less first boot, & second time about ~10 Seconds! amazing!
I Very Recommended to buy the Transcend Class 10 once... it's very perfect very speed! also cheap, on amazon about $15.
microSDHC Transcend Class 10 8GB ***** 5 Stars for boot Android

yes.nwo i will list the cards that i used.
1.all kingston 's tf card is ok. all can successfully get into the system. the entering time depends on your card's speed. class2 is the slowest,but can be used.
2.most of Sandisk's cards cannot be used. althought you can format it by using the tools, it cannot get into the system. the mistake is that the memory module is different from the others. but Sandisk 's speed is faster than other cards,which have same class speed.
3.samsung and toshiba all OK, can fluently use, just class2 is also fast like class6...
4.some of the none name card can be used, like nokia's normal card,some cards that is given when you buy you mobile phone.
sorry for my poor english..

Indeed, Class 10 Transcend is very good. However, I still have to manage android boot optimization because a lot of installed apps are slowing the start-up process, even with the class 10 µSD...

Of course, that's right!
but about slow start-up process, second time is ok even restart android. but I could know why shouldn't first time be ok? also... it's not brand's problem.. maybe because SDHC are like that... or NAND?

thanks!
i just ordered the TS8GUSDHC10 on amazon for 13euros, will let you know if it works good

I have two of them, both working pretty good: 13M/s write and 18M/s read

Strontium 8Gb works
I have a Strontium 8Gb HC card don't know other details but it works even with winmo folders.
Only all the android files should be in root.

Nice, now you can install (if you want) this app: SD Tools on HD Mini to see details of your card
and this on PC, to measure the speed Crystal bench mark (Portable Edition (zip) for Windows
Here's Manual
So if you have 2 or 3 cards, with this you can measure and compare and know what is better for you
Note that Random Write 4KB (QD = 1) is the most important when it comes to Android port (wich boot and runs on the Micro SD card)

installed SD Tools and these are the results
Manufacturer SD08G
Write speed 5.3MB/s
Read speed 14.3MB/s
Class ?

I tried installing android on 3 cards that i have, but failed.
The cards i used are:
-sandisk 2gb, the one that comes with the phone. (It is reported not to work so i dint care)
-no name 2gb sd card (no class info, but it seems to be class 2) which was provided stock with a nokia phone. I expected this to work since mooncmn had reported it working in the earlier thread.
-transcend 4gb class 2 card
I have formated all cards in sd formatter with full overwite and format adjustment off and then format fat32 on winxp and then i copy the files into phone. All this i do in "disk drive" mode. Then i remove the usb cable and load haret.
I tried out several versions of android as well:
-googlecode : I tried it multiple times on all 3 cards waiting minimum for 10 and upto an hr. When i reboot to wm i can see data.ext has stopped at 30mb on all cards irrespective of the time i let it load.
-munjeni and cm6 : both had the same problem as above, it stops at 30mb which is strange. in munjeni's version it stops at a point which i have attached the pic.
cortulla's port : This version actually worked but had to wait for atleast 2 hours first boot and even then it ran extremely slow, which was unusable.
As for base rom i'm using nsourm's latest WWE rom. Does this have an effect on android?
Ultimately i think all 3 cards are incompatible, ill try it out on other cards. Anybody have a suggestion for a 2gb card that worked for you?
Thanks
EDIT: Transcend 8gb class 2 worked for me!

Hi Everybody,
today I tested 3 SD cards. I stoped booting time of Android from run Haret to first Android "Lock Screen". Here is my result:
1) Kingston 8GB Class 10
Android booted in 1m 30s
1) Kingston 16GB Class 4
Android booted in 1m 28s
1) Sandisk 4GB Class 4
never booted
And... I solved all problems with Android on my HD mini, because I dropped my phone and is broken... I ordered new display from eBAY (20$), so I hope, will be functionaly.

You need to install new rom (including spl, radio...etc)... Allready confirmed by guys who instaled new rom that all forking perfect now after instaling new rom and radio!!!
RUU_Photon_HTC_Europe_1.36.401.1_Radio_Signed_32.2803.05.06_0.63.05.36_Ship.exe

Working perfect with RUU_Photon_Vodafone_SPA1.41.164.1_Radio_Signed_32. 2807.05.06_0.63.05.41_Ship.exe. Newer ROM and Radio

I've tested Transcend 8Gb class 10 for several days
my conclusion:
compared to my SanDisk 4Gb class 4 is the Transcend at least twice as SLOW in booting Android and apps, is LAGGING a lot and drains my batt very fast!
I'am very happy with the SanDisk

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.

Ooh nice! Thanks, will buy one now.

Transcend 32GB SDHC Class 10 card on my Desire for 2 weeks, feel fine.

Got the card. Works flawlesly. Also increased the SD card read cache to 2048kB, I get a write speed of 11+MB/sec, read speed of 25+MB/sec now. Nice

Anyone got a UHS-1 microSD card working?

I've been at it back and forth with Asus and SanDisk support now as I have yet to get my SanDisk Mobile Ultra 32GB UHS-1 card to work properly in the TF700T.
First card worked erratically and died completely, second card doesn't work at all.
The log of the tablet sais read errors but the card work perfectly in both PC and android mobile (x10 Mini).
Tablet sais it's DDR so I assume it uses DDR50 mode which is the most complicated mode to use due to the data timing.
Has anybody else got a UHS-1 card and had it work reliably in the TF700T ?
When mine was working I was getting sporadic read errors causing copy file from card to device to fail, and video to stutter.
(File copy was aborted by "paste files failed" message.)
These cards would offer much improved io performance vs a normal card and their improved latency should make em improve responsetime too.

I popped by a shop today and tested the UHS-1 card in a TF300 too. It got a hissyfit and went into a mount-loop.
Bought a SanDisk FCS-HS3 UHS-1 compatible USB3.0 reader to test the card on a pc and it performs great. (Well writes are within class 10 spec, and reads are fantastic.) See attached Atto run.
Also got a 32 GB Class 10 Lexar card to see how the TF700 likes it. No problems and everything seems smooth.

I have Sandisk Ultra Micro SD SDHC UHS-I 16GB Class 10 30MB/s and it's been working fine so far, it even rescued me when I needed a firmware update after bootloop, only with lower write speeds than SD, USB disk or internal memory (somehow I get somewhere near ~10/20 W/R on internal and ~20/10 on SD, pendrive, USB HDD etc., btw, seems a bit strange to me, as I would expect it the other way around).

That sounds like how my first card performed. Not fast.
I wish the SD test apps could show a graph like HD Tune on pc. To see how smoothly the card operates.
I know that any errors are masked by android and it resets card and continues thus making a card that hang all the time just appear slow.

It is not about UHS-1 though, I get the same with USB pendrive or HDD.

This is the same test on the same card in a NON UHS-1 reader.
As you can see the readings are drastically different.

Sorry if I'm missing something, but on your screenshot I see 19 MB/s read and 9,5 MB/s write on average on your PC, so how is that different from what we were discussing as the speeds we were getting on the tablet?
Edit: I see your earlier post showing 40+ MB/s read speeds, but this was USB 3.0, wasn't it.
Edit: I forgot we were discussing microSD speeds. If you get 19/10 on your PC, this is in fact 50% more than I'm getting with microSD on the Infinity. It surely shows a major difference.

Yes, USB3.0 with a reader using UHS-1. The UHS-1 is the most important part as that increases the bandwidth between controller and card and also reduces some delays on completion etc.
On the tablet I was getting good speeds and then pauses/breaks getting the average very low on old card. Log showed errors. New card doesn't even mount.
Edit:
It does however show how the tablet is trying to moungt it and what speed it talks to it, also what capability it has.
Edit2:
USB 2.0 can do 40 MB/s too btw, but usually max 30-35. The UHS-1 makes the difference.

For bigger data transfers I'm actually relying more on full-size SD card in the dock or USB disk. Which is of course a possibility only if one is carrying a dock..
---------- Post added at 05:56 PM ---------- Previous post was at 05:54 PM ----------
Yes, there is no question we have the lags to blame. My microSD writing speeds start with 30-35 MB/s for a few seconds (which is a lot more than I'm getting on my laptop with this card), then the lags make it drop even to 6 MB/s. So these are all the I/O issues we were discussing in so many threads here. Not much will come out of further benchmarks until we get an update (JB / kernel / smaller firmware fixes / hopefully anything)

Untill the 17'th I won't have access to any docs...
Attached is a shot of the dmesg output from where it detects the card.
Notice it registers it as a ultra high speed DDR SDHC. DDR must mean it is considering using the UHS mode DDR50 which is a complicated mode requiring calibration. It also seems to assume/try NTFS first.
I can't see any attempts of uing card in normal SDHC mode after the UHS failing, nor any normal non DDR UHS modes.

I'd like you to scour your dmesg log after one of those glitches, and also after inserting the card to see if there is any significant difference.
My card dipped in speed but usually did not log errors. I think the first retry is not logged if successfull.

I don't get any errors after (re)inserting the card apart from those from tntfs saying the boot sector is invalid, so it's quitting after finding out this is not NTFS (because it is FAT32 ;>).
Tell me what errors do you get specifically, so I could grep my logs looking for them.

Sorry, I missed the last post on the previous page.
Doesn't look good, I don't get any of these in my logs apart from the NTFS assumption, which might be the normal thing (a late attempt to solve the NTFS compatibility issues).
I would try sio if I were you.
Mine doesn't say anything about ultra speed DDR SDHC however, it only gives the "new high speed SDHC card" output..
I'm not sure what you mean by saying that it doesn't treat it as SDHC afterwards - where would you want to have it reported?

Your card works as it does not infact support UHS-1. It's probably one of the "Ultra" cards not "Ultra UHS-1".
The difference is a small U on the card with a 1 in it. (See attached.)
Sandisk has the same card in identical packaging, except for the UHS-1 support. The difference is drastic on PC, and apparantly catastrophic on TF700T and TF300.

In fact, mine is not UHS-I, but regular SDHC, sorry about misinforming you, I was initially thinking about getting the one you got yourself and then misclicked on the auction, LOL, I can see it now, bummer! I think it's even class 4, not class 10 (how much slower can it be because of it?). My full-size SD in the dock is UHS-1 and it's been performing well (Sandisk Extreme 32 GB 45 MB/s class 10).

Thanks. Definately a non UHS card.
So far I've found or read about Sandisk Ultra in these flavour:
- Sandisk Ultra XXGB Class 6
- Sandisk Ultra XXGB Class 10
- Sandisk Ultra XXGB Class 10 UHS-1
- Sandisk Mobile Ultra XXGB Class 6
- Sandisk Mobile Ultra XXGB Class 10
- Sandisk Mobile Ultra XXGB Class 10 UHS-1
The packaging on my card sais SanDisk Mobile Ultra but the card sais only SanDisk Ultra. (First card said Mobile Ultra.)
It's really odd how there is always differences on pics I find.

Yeah, mine is not ultra, terrible miss-click. I will use it in the phone probably and will order UHS-I class 10, unless others report same problems as yours.

Could you insert it and check the log?
See if it does anything different on it vs the other?
Unless it has any U on it it will probably only do standard SD speed of 50 MHz givingv 25 MB/s max datarate.

microSD

I bought this for my phone, and it is not working Lexar 32GB Mobile Micro SDHC Card- Class 10

I don't know what cards would be compatible with this phone, but in the past I've found that formatting a card on my PC has sorted non-working ones out on my phone. Have you tried that?

Yes i've tried formatting it in all possible formats.

sandisk worked
The sandisk one worked for us:

known bug - microSD not working
According to several Nokia.com discussion threads, this is a known bug with the 820. The card might work for a few minutes, but soon goes corrupt. The card can be re-formatted OK in a PC, and phone will recognise it again (but only for a few minutes). If you've changed the settings to store photos etc on the card, the camera will also stop working when the card goes corrupt (because it can't store the pics anywhere).
Apparently a patch is due one day to fix this...

If you've changed the settings to store photos etc on the card, the camera will also stop working when the card goes corrupt (because it can't store the pics anywhere).
Apparently a patch is due one day to fix this...

I can confirm this through experience. Pretty bad issue since the phone only has 8GB of internal storage.
I have tried the following cards and have had the same exact experience:
Sandisk Ultra 64 Class 10
Kingston 32 Class 6 (I think)
Trancend 16 Class 10

For me, the SanDisk Ultra UHS-1 with 64 GB works fine WHEN I reformatted it on the PC to fat32 with this tool: fat32-format.softonic.de
Before, the phone recognized it, but crashed and I couldn't move files to it. After formatting, no more problems

I have this card here
SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-064G-AFFP-A)
Worked as soon as it was inserted to the phone and I have several videos and photos on it. 58.X GB formatted capacity. I would not recommend using a card that is NOT listed as compatable with the phone.

abu majid
is there any solution to move apps to sd card??

Not at the present time ^^

I got an update on the 19th, when the phone restarted everything worked with my Lexar 32GB Class 10(i'd actually forgot that I had it in there), so the issue seems to be solved now.

TurboTuck, thanks for the info.
Have you loaded the microsd with more than 10Gb? Issues usually occurs when more than this amount is loaded to the card.

...mine is working perfectly with a 16 GB class 4 microSD sandisk card.

Anyone tried a 32Gb class 4 microsd?

Just to throw in my .02.. I reflashed my 820 last night and the SD card is still working fine.. It is an 8 gig class 4 I believe. I have a 16 gig class 10 somewhere that I will need to try.
I'm still holding off on really celebrating, though.

Kingston cards work always for me
16GB class 10 here

I bougth a Sandisk 16Gb class 4 and it´s working perfect.
I already loaded it with 12Gb and has no lag at all.

I have 32Gb class 10 from SanDisk. It works perfectly not in 1308 and former.
