Well fine sir, I rebooted and then downloaded notification refresh. That did the trick. At first it was only the theme that wouldn't cooperate but now it works just fine. :) PS I replaced my speaker so I'm patient again.

I'm after a 32GB Micro SD for my phone but I'm unsure which is the best way to go. A part of me is thinking of getting a Class10 but I know that a Class10 sacrifices R/W rates for speed which is making me unsure. I only use my SD card for Music Playback & the odd Photo & Video I will take, I dont store Apps on the SD card (No point with the huge internal space in the G2!) Is it better to go for a lower class (Like Class4/6) or will the Class10 perform well enough?

And is there any 32GB MicroSD's you can recommend (or warn me off!) I keep looking at this one:

Lexar 32GB Micro SDHC High Speed Card with Reader - Class 10 Extreme Speed

But the one review kinda puts me off.

What do you guys/girls think i should go for?

Thanks in advance :)

I have a sandisk class 4 32GB card and works like a charm. Been using it for 6 months now with no issues

dont send me pm's crying about how i hurt your feelings in a thread
[G2 and Desire Z Accessories] KarlosTheJackal:
If you don't mind me asking, what Read/Write speeds do you get with it?

I've been doing more research today on this & getting more & more confused 0_o I don't understand why some places say Class10 is always the best & some say that it sacrafises so much to make it that fast that its better for a lower Class. I always thought that the best you could get was Class10.

My head hurts :-(

[G2 and Desire Z Accessories] polarbearmc:
haha mine too. i get so confused about that. i'm looking forward to seeing a definitive answer on this thread.
[G2 and Desire Z Accessories] ilostchild:
from what i understood with class is how fast it r/w higher the class better the r/w

but i could be wrong on this too

from what i gather if your device can handle and utilize the higher class then it will be good but if it cant then a lower class would be better

example

so if the phone can handle DTR class 10 then you will see it able to write at full 10mbs but if it cant you will see that it sluggish and sorts of issue and as well see that a lower class card (class8) would out preform the class 10, this is cause the phone can fully take advantage of the class 8 speeds of DTR

thats what i gather and understood, once again though im not fully sure if this how it truly works
[G2 and Desire Z Accessories] DeoreDX:
There is a little misunderstanding about SD card speeds. The card class only tells you the sustained write speeds. This was important information for people with cameras (still and video) and why the class was invented. What class does not tell you is read speeds and random access speeds. These are the factors that effect performance in the way we normally use a microsd card in our phones but are not ever advertised. I've found regardless of class Sandisk cards normally score pretty high on the last two values so I almost exclusively stick with them. I'm using a class 2 Sandisk 16gb which measured 3.7mb/s write speed just below class 4 and 18mb/s read. Toshiba has been really good too. On the other hand I had a class 6 PNY that was barely usable in a phone because it's access speeds were so slow it caused noticeable lag in the phone.

Patriot 32gb Class 10 cards go belly up and corrupt your

Data when it hits 16gb of storage . Its a well known issue

With Android phones using this card . Patriot even acknowledged it . For now i would stay far away from them .

[G2 and Desire Z Accessories] ratchetrizzo:
True, they issued a statement about that card and android/wm7 phones.

They also said there is a workaround that "usually" works. format the card fat32 with 32k clusters.

I decided to try it, and so far for like the last 10 days my card has been alright. I loaded it music and did a bunch of nandroids, because nandroids were usually the first to become corrupt.
[G2 and Desire Z Accessories] blackknightavalon:
I've had my Wintec card for just over a day and I have no complaints whatsoever with it. I'll let you know when I use more than 20GB of data on the card.

Everything works the way it's supposed to.
[G2 and Desire Z Accessories] burtcom:
Yikes -- well I just copied all my crap to the new card, and so far so good.

But I better copy it back, reformat as you say, then reload the data.

(for almost $100 this card better be reliable -- it IS fast, thats for sure)

I see now that Patriot is saying this is "Industry Wide" that could affect other 32GB class 10 cards, not just theirs.
[G2 and Desire Z Accessories] gravis86:
I saw no need for a Class10 card. I got the SanDisk Class4 from BH Photo and it is performing admirably.
[G2 and Desire Z Accessories] sino8r:
As long as its above Class 2... you should be fine unless you use A2SD (might wann go with a class 6 or higher) which isn't really needed on a Desire Z/G2. Avoid the cheapo cards because they corupt more easily. I always back up my card every couple of months or so just because of past experience with cheap sd cards but last couple of years I rarely have that problem with Sandisk cards. They corrupt after a year or so but regular check disk utilities (every 4 months or so) and occasional defrag (one a year or so depending on your usage) can prevent coruption or problems.
[G2 and Desire Z Accessories] Spastic909:
Higher Class doesn't always mean better. Not going to explain but google can help. As far as my read write speeds I've never had the need to find out because its fast. I'm critical on stuff so if I felt a problem growing I would check.

dont send me pm's crying about how i hurt your feelings in a thread
[G2 and Desire Z Accessories] blackknightavalon:
I'm well aware that there's no "regulatory committee" checking up on the classes of each individual SD card mass-produced and sent to retailers. My Centon 16GB Class 6 card worked better than it was supposed to (except for one time when the data on both partitions got corrupted), and the Wintec card I'm running right now does write at 10MB/s. If you're looking for a cheap Class 4 card that performs like a Class 6, go with PNY.

haha this thread is so totally not useful. it's like searching for how many advil to take for a headache. don't take more than 1! oh i take 6! i take 3, twice a day! i take 4, 4 times a day!

This is what ive been finding basicly all over the internet, conflicting advice & recomendations. Its kinda why i started this topic to try & get some clarity but i guess that isnt the case.

Then again i wouldnt call the Thread "not useful" I have found a load of information out about card & manifactures etc. unforantly nothing soild, Hopefuly with more people jumping in & contrabuting to this thred then we might get a answer as to which is the best 32GB MicroSD card to go for. :)

P.s: Sorry for any horrable spelling/grammer errors, typing this in a rush as I'm about to go out!
[G2 and Desire Z Accessories] mputtr:
This is all about people's experience with their cards. Yes it conflicts and that is why it's being discussed here to try and find a common reason to why it does "x" and what class to buy and the real differences.

No need to be a jerk about it. If you can't contribute and prefer to bad mouth, then it's better off being kept to yourself than making worthless comments like yours
[G2 and Desire Z Accessories] polarbearmc:
sorry, i just couldn't help myself this time. it's just one of the most overly conflicted threads i've seen in a long time. i was real disappointed cause i was hoping (like the op) to get an answer of some type. but we're all just worse off than when we started at this point unfortunately. if i hear of anything definitive elsewhere though i'll be sure to relay the info to this thread.

np. I just don't like to see people come in and come off as putting others down because they're all trying to work out what is going on and how to understand it. That's what XDA is here for. learning and understanding what we use with our phones.
[G2 and Desire Z Accessories] blackknightavalon:
I will say that, in the week I had it so far, the Wintec card runs exactly the way it's supposed to. The Centon card I put in my wife's nookColor was also reliable and i'd still be using it if I didn't need more storage.

I've got a Wintec 16GB class 10 and I'm lovin it. I put "SD Increase" from the market on my phone to help speed things up *enlarging the cache I think*, and Not great results... I'll probably remove that app. But happy otherwise.

Hi guys. Just received my sandisk 32gb sd card.

Either using my phone, or a computer, how should I go about formatting it? I'm pretty sure I want to make this an ext 4 right? If its anything like the G1s then can i do it in clockwork?...I just need some recommended values. for whatever it will ask...swap, or whatever it wants me to set.

Also...when transferring data from my old sd car to my new one....is it as simple as dragging a copy of everything into the empty card?

Thank u Guys in Advance.
[G2 and Desire Z Accessories] KarlosTheJackal:
You only need to make it an ext4 if your planning on using it to increase the internal size of your phone. If your just planning on using it as normal storage (for music, pics etc) then Fat32 will be just fine :-)

Heya, do you mind running a speed test on it? I'm looking to buy a 32gb card from sandisk via amazon as well and I've heard them talking about sandisk removing the class from their non high speed cards so you can't tell what class it is. They do claim that it's now a class 4 but I'd like to know if sandisk will be worth getting via amazon.

So, would those 32GB users please post a response after they had it a while. My 32GB card died in 2 days, switch to a 16GB, that one is filling up.

My 32GB card overheated (got the G2 very hot), so I was curious after that and put the card in a sd card holder in the computer, and it overheated so much it melted the holder (have pics), so needless I am following this thread.

So please post your experience, and thanks.

[G2 and Desire Z Accessories] PermROOT:
But in awake of the problem solution was found. But not thanks to Patriot Tech Support that is as its recommended you backup your data and reformat the SDCard without no LBA support using low level format which will take close to an hour.

Do NOT use SDFormatter Tool as it has LBA support. So use Check Flash which you can Google it for link as its free. This should work for everyone and cut down the issue. For me I have been using it normally and didn't run across that issue as I stated since beginning of the thread after I got one of those bad batch.
[G2 and Desire Z Accessories] blackknightavalon:
Just got my ADATA card in. I'll post how it works after a week or two.
[G2 and Desire Z Accessories] aniym:
So at this point would it be safe to say that a good portion of 32GB Microsdhc cards on the market have problems (the 16gb limit, the corruption, etc)?

I'm selling my mp3 player and making my HD2 my primary music player, so I'm trying to decide between a 16GB and 32GB card.

16GB would be OK for now, and I think I can get it for about $20. Is it worth spending $55 on a 32GB Sandisk card if there's a risk of data corruption down the road?

I've been using an 8GB Class6 Transcend MicroSD card for about 15 months with no problems.
[G2 and Desire Z Accessories] mputtr:
I've been noticing that Sandisk seem to be the most reliable of them all. Although they do not specify class speeds for their non high speed cards, people have reported (with test results) that the speeds range from class 4 all the way to 8.

A phrase I seem to read about alot is that Sandisk is a little shy on the actual speed but it's reliable.

I have the card sitting in my amazon cart right now but i'm still on the fence on getting it still......

I got this one and it works perfectly. Not a fake as I copy 29GB of data without a problem.

it is . How fast does your gallery , videos , etc. show/load ?
[G2 and Desire Z Accessories] initial_k:
it is very decent. Gallery load up normally without a problem. I didn't notice any usually lag.
[G2 and Desire Z Accessories] blackknightavalon:
I've had the ADATA card for over a week now and it's definitely better than the Wintec card was on its best day. The 2GB sd-ext partition doesn't lag and the phone boots up very fast. I highly recommend this card.
[G2 and Desire Z Accessories] Nighte:
To put it simply, the higher the class, the higher the minimum R/W speed should be. The better the brand name, the more reliable the card should be.

Lastly, keep in mind, you generally get what you pay for.

Simple enough? :p

That said, I've had no issues with the many SanDisk MicroSD cards I've had. Even class 2 will perform just fine on a phone.

Just stick to brand names like SanDisk, ADATA, etc and you'll be okay.

I got a class 2 SanDisk 16gb MicroSD in my phone and an class 10 ADATA 32gb MicroSD in my tablet and they both perform as they should. :)

[G2 and Desire Z Accessories] mputtr:
where did you get your card from? I know I bought one from ebay that says it's 32gb class 4, but when I got it, it would not store past 4 or 5 gigs. It's a fake and after talking to the seller, he also realized that he bought a stock of fakes so he accepted my return and refunded me. Try amazon, you should be fine.
[G2 and Desire Z Accessories] blackknightavalon:
It's also luck of the draw. I'm hesitant to buy a SanDisk card because I had bad luck with one when I was trying to use the original A2EXT mod for the G1 and the card got corrupted (the exact same method worked on a PNY card that's still in use with someone else). I doubt I'll buy WinTec again, but I'll vouch for ADATA's speed as long as the card's FAT32 partition doesn't get corrupted.
[G2 and Desire Z Accessories] mputtr:
that too. On Amazon, the 32gb Sandisk card comes with many many real and fakes. Alot of it are solt by Blue Proton and the reviews flip between real and fake, so yeah, it is luck of the draw. but atleast if you're using amazon, you should be able to get yourself time to return it if it's fake. and if you're not sure, you can always confirm with sandisk and if it's real, you're all good, if it's fake, return it and your money back.

so much for class... From now on I would only stick with Sandisk.

I have a Transcend class 8 8GB and a sandisk Extreme 8GB SD that I use for my Canon D550/T2i, which could shot in 1080. When you put the transcend in, 2 sec later the recording stopped because the card can't handle the amount of the data coming in. With the Sandisk, on the other hand, I could film the whole card.

I'm sure there is much difference between a camera and a smartphone. However, you get what you pay for and Sandisk is the best there is.

[G2 and Desire Z Accessories] taob:
Given the uncertainty over certain 32GB cards (maybe it's just Patriot...) and that I survived quite well with an 8GB card on my Hero, I went with a Transcend class 10 16GB card for my DZ. I don't really need fast random I/O, but rather sequential read/write speeds would be beneficial for nandroid backups and copying them off the phone to my desktop. I am seeing about 16 MB/s sustained reads with the phone plugged into USB. A 1GB nandroid backup set takes about a minute to copy off the phone.

A dd with 32k block size from the DZ's command line gives me an average of about 17.8 MB/s reads and 14.4 MB/s writes. Compare this to 29.5 MB/s reads and 19.9 MB/s writes to /data (internal flash).
