buyed Bad SD Card? - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

Hey,
I am just flashing Windows Phone 7 on my HD2 now... I buyed a "Class 10 16GB Card" from a German Reseller (Media Markt) today. But while Im flashing using DFT I just have a Speed from 61 kbytes/sec... I think its not that fast, is it? Have I buyed a "fake class 10" card or something? what do you think?

Than Ill just go to MM on monday and ask for a refund. I will get one

just started again - was copied over in 1 Minute ca Works great But still some kind of slow

I have both 8GB class 4 and class 10, after 1 week using, Class 4 still best for WP7. With Class 10, I got restart many times

lol this is dragging up some old threads!
righty, quick SD card lesson
WP7 needs quick 4KB RANDOM writes/reads there are various threads showing you want seems to be best
Now, Class 2 and Class 4 have slow sequential speeds, compared to class 6 and 10
The class system is defined by srquential speeds, this is useful info if your using it for a digital camera, the higher the class rating the quicker you can read an write those large files
However windows phone 7 doesnt mess about with large files, it needs to access many smaller files in a random order.
Now, They way in which SOME SD cards get higher sequential speeds (and thus a high class rating) is by working some magic, unfortunately this same magic has a side effct of reducing random access, so the general rule of thumb is this
Class 2-4 will give you a higher CHANCE of working
Class 6-10 will give you less CHANCE of working
I say chance because apart from some PNY class 2 cards there are not any cards out there on the market sold as "high random access speeds"
Its luck, pure an simple, a Sandisk 8GB class 2 might work for one person, but not someone else, the reason for that is almost every card is made differently.
So statistically you will have better luck with a class 2 or 4.....

When moving to Yuki-Xbmod Mango rom I had 4 SD cards
16Gb Transcend Class 4
2Gb Sandisk Class 2
4Gb Kingston Class 4
4Gb "No Name" Card
The "4Gb no-name" card was the only one that worked.
I needed at least 8Gb and I didnt want to buy one and take teh risk so after asking my friends and trying there cards I found a "8Gb no-name card" that worked and had no choice but to swap my 16Gb card for a 8Gb card!!
My experience shows no-name cards work better.

memory cards ..

hi guys
my pro comes during next week and i wanted to check what size memory cards it'll take. If it supports Micro SD will it support Micro SD HC cards? What's the maximum size it'll support please?
thanks.
http://www.htc.com/europe/product.aspx?id=49936
see the photo number 6
so for £17 an 8GB SDHC card from play.com is my best option really? Any other suggestions?
That's even cheaper than Ebay!
I bought a 2GB Sandisk one from Play for my Artemis and it buggered my phone! Play were a bit arsey about replacing it, but did eventually after a load of emails and phone calls
8 gig rox!
I have 2 8 gigs that I switch back and forth...it was kind of funny to use my phone as an external hard drive via usb! The phone also has disk mode, faster communication to the sd card...
Its almost sick as we keep getting more and more memory! pretty soon we will get rid of moving part drives and everything will be memory!
I've bought an 8gb sandisk class 6 with p&p for around £27 off ebay.
Don't forget that there isn't just size, but speed as well.
As far as I know, the current 16gb cards are class 2, even though some places are stating 4. (I've not come across anybody that can prove they have a class 4) And sandisk isn't even showing details themselves yet.
16 gb microsd class 4 does not exist.
there is only class 2 for this size, the rest are fake!
class 2 should be enough for regular user though...but then again, who on this forum is a regular user? )
I have a Sandisk 16GB Class 2 card - works perfectly.
Does anyone know what Device Class the Touch Pro is?
There is no need for a class 4 card if the unit is a class 2...
Is there any good benchmarking programs for reading SDcards on WM6.1?
16gb, saying class 4 £46.95 http://www.memorybits.co.uk/shop/mi...23-in-1-multi-card-sdsdq016ge11mplus23in/9078
have ordered from them before no issues
No one is selling Class 4 currently, their information is incorrect - many others are similarly stating Class 4 but shipping Class 2. Class 4 is not yet available.

I use Pocket Mechanic on my Tytn II (still running WM6.0); it has a pretty good benchmark suite. I ran it on a SanDisk 16 GB Class 2 I picked up the other day and got write speeds of 1.3 MB/sec. The same test on a SanDisk 8GB Class 4 gives a write speed of 2.05 MB/sec. Those numbers suggest to me that the device is the main impediment to performance -- I should have seen at least 2MB/sec and 4MB/sec respectively (that's what Class 2 & Class 4 mean).
And that's a Tytn II but I'm very interested in what difference it makes in a Touch Pro..
my choice is between the:
Sandisk Mobile Ultra microSDHC 8GB (Think it's class 6) (€38,50)
and the
Sandsik microSDHC 8GB (Which is class 2) (€24,95)
And I really don't know which one to go for.. I somewhere found a Nokia N95-3 review which told that the difference was noticable between the 2 cards.. but I don't know if it's true for the TP..
Any help on this matter?
You guys really need to steer clear of Ebay for memory, to many fakes of rubbish quality, I have used both of these places before and they are excellent and reliable, I just bought a genuine Class 6 sandisk 8GB micro SD plus a keychain USB adapter for £26.50 delivered, from the first place
www.picstop.co.uk
www.7dayshop.co.uk
The pro is class 4 or better i tried wth c1 c2 and c4 cards c4 works the fastest almost 16mb transfer speed via the phone that is not bad.... a full os flash from c4 card take just 5 min nbh image size 154mb so talking about a heavy-weight os. but the same progress with my 4 gb c2 card take over 10min ???? funny
The SanDisk 8GB Mobile Ultra class 6 is superb!!
I've bought this Sandisk micro SDHC 8GB class 6 at 'The phone House' for about 40 euro. The class 4 device was 10 euro less expensive. Yes expensive but worth every cent. I've used several brands the past 6 years and I'll stick to SanDisk: reliable no issues at all and fast!
At this moment 16GB is available but only class 2. Don't buy them because you don't want a bottle neck in your overall system performance!!
Woot has 4gb MicroSD cards for $11 shipped. I just snagged two, but hurry the deal is only good for one day.
i actually emailed HTC about this and got the following email as a reply
Code:
Good Evening,
Thank you for your enquiry about the HTC Touch Pro.
The Touch Pro has been tested with a 16gb MicroSDHC card and it works fine, as for 32gb and 64gb I cannot be sure, as they have not been released yet. More information bout the compatibility of these cards will be available after they have been released and tested.
Please do not reply to this email as this email address is not monitored for replies.

What Micro SD Card: Class & Brand

Looking forward to finally turning my phone into my day-to-day mp3 player, as well as running debian and apps2sd, I've been reading all the latest threads about sd cards and finally decided the most optimal config is a 16gb class 4.
Reasons:
· Class 6 is unnecessary as the nexus wont really take advantage of it.
· Class 2 may be kind of slow for apps2sd and debian, which I'm looking forward to investigate on.
· 16gb because although 32gb is comming, it will probably be too expensive for me.
Benchmarks:
I've looked through eBay and found a few interesting "offers", both at about $40:
SanDisk 16GB Class 2
TOPRAM 16GB Class 4
I really want a Class 4 for all I've been reading lately, but I can't afford a 16GB Class 4 SanDisk.
Does anyone know anything about "TOPRAM"? I had never heard about it before and I'm wondering if it could be a low-quality card.
Any help will be greatly appreciated.
No one knows ANYTHING about TOPRAM?
I've seen ppl complaining on the internet about the device not recognizing the sd card, but i guess that happens sometimes..i think..o.o
I have always used A-Data cards, been happy with them.
here are some speed test people have done http://wiki.cyanogenmod.com/index.php/SDCardSpeedTests
I use and trust PNY class 4 sd cards never failed a year in my rooted g1 and still going with apps2sd and so far with my nexus

With all the talk about SD card speeds I've been seeing lately, I was starting to regret buying the SanDisk 16gb class 2 and not getting a Class 6. But after looking at this chart, I can't imagine why I would need more speeds than that?

I have a 16GB Team Class 6 from ebay
I'm using a Polaroid 16gb class 2. Seems to be working fine for me, even running apps2sd.
I have an 8gb class 6 from RiData. seems fine to me, used on my MT3G, HD2 and now my N1.
i do agree with you though that a 16gb class 4 might just be the best cost/performance
Since we are talking about storage memory, I have a slightly unrelated question. Which is the better, microSD or internal storage that comes with some of the phones out there? In terms of speed, reliability, and cost, which one is better?
With regard to Class 6 - don't write it off if you plan to remove the card from the phone to do movie or music transfers. There are a lot of microSD adapters for computers that can exceed the performance of a Class 6 card and so if you are commonly hooking it up to a computer to transfer media then you'll be glad you went with a Class 6.
Now, if the capacity gets high enough to store all of my music, then I won't care about that issue, but personally I can only store a subset of my music on my microSD card so I do worry about the speed when attaching it to a computer...
i have that TOPRAM sd card on my nexus one i got from amazon Usa and it work very well
Class2 is definitely slower
I've used classes 2, 4 and 6 in an HTC Magic. I used apps2sd with Cyanogen Mod.
My own experience was that Class2 was definitely slower when using apps2sd. But Class4 and Class6 were better...and didn't appear to be much different. I had Class6 sdcards anyway as that is what was recommended for most of a year. They performed well.
The last ones I bought were Class 6 8GB Transcend MicroSDs for NZ$40 each (US$28-ish). That included 12.5% GST.

Where can I buy 32GB microSD in Atlanta GA

Hi
Where can I buy 32GB microSD in Atlanta GA?
What Class of microSD is recommended for for HD2 running Android? is Class 2 enough?
Thanks
i don't recomend you to buy an MiicrSD 32GB....
Why? the max i see is class 2 ( low data transfers ) and if exist a class 4 or 6 will be expensive... over 200dollars or more... ( i guess )
You be OK with a micro sd HC of 16GB class 4 or class 6 ( i have one of class 6 and works GREAT! )
If you still whant an sd of 32GB please search on ebay, or other smartphone webs.
Excuse my bad english.
PD: The minimum recomended For me about the class, it's class 4, class 2 works like a ****...
i have a class 2 4gb and other 8gb, and works Slooooow.... but my 16gb class 6 works faster!!
A class 4 32GB microSD does indeed exist, but it's ~$160. And I still recommended having class 6, which does not exist in the 32GB size, yet. Just stick with your SD card and keep your money.

People are saying that we should use a Class 4 SD Card. Same ole BS, HTC puts in a Class 2 and then still ships out Class 2 as replacements. Figure that one out. I know $$$$$. LOL
I don't think you can even run Android with a 32Gb card. I've heard the best card for Android as far as battery consumption and speed, is Kingston 8Gb Class 4.

Android will run with a 32GB card but that's the most the OS can address.
Sent from my HTC Incredible
Thanks for the replies.
My current microSD is 16GB Class 2 (Sandisk) and it is running Android with no issue at all on my HD2; so I think that a 32GB of the same Class (2) will not under perform. Since I want to try and compare between several Android builds, I need the space. I am going to be in Atlanta this week, that why I'm looking for a place where I can purchase a leget card. In the past was burnt twice when I purchesased "fake" SD cards via eBay.
Doses any one run Android on HD2 with Class 2 32GB and facing problems due to the card?
If you guys know of a leget place (e.g. Best Buy, etc.) that have the card in the Atlanta area, then please provide the location info.
Thanks again.
Check at a verizon wireless store. Here where I live they were running a promo, if you bought a droid x, you could purchase a 32gb micro at a discounted price.

wouldn't be easier and cheaper to buy a card online and just ship it overnight?
or, walk into a verizon store and they'll charge you plenty, but for a legit card

SDHC Class 4/6/10???

Hello!
I want to buy a 8gb class 10 mSD for my [email protected], but i see some other thread from other forum, they said that the maximum r/w speed on HD2 is only about class 4,
Which means if u insert a class 10 (or class 6) sdhc card, actually, the speed was only class 4's speed...
Is it true???
Thanks
That will be good to know, because I was thinking of buying a new card as well.
The G1 and MT3G can support up to class 6...I'm sure the HD2 can support class 6, not sure about 10 though
You would be fine with C6 cards just make sure you don't buy any BS get it from reputable dealer. Using SD2.0 on HD2 you won't see passed class4-6 as the device is limited but not the card, you can however get class 10 card and use card reader to transfer content but while the mSD is in HD2 you will be throttled near C4-6 range. IMO go for C6 if you plan to use any type of heavy use that would require large access on mSD if not then go with C4 you will be perfectly fine.
People worry too much about card class. I'm using a fairly standard class 4 card and I've never been frustrated even when copying android with a 1gb data image to it
I cannot see any difference speed between class 4 and class 6 8gb SD card. anyway, be sure to buy a known brand name.

[Q] SD or SDHC

Looking to get myself a 32gb card.
Just wondering if the play uses SD or SDHC memory cards, or ok with either?
it uses microsd and microsdhc
regular sd card wont do
Yeah, obviously I know it's micro.
Just wasn't sure about the sdhc.
Cheers
It's ok with both sd and sdhc but I think it's not compatible with sdxc (if you'd ever like to get to 2TB maybe it can come in an update, My htc wizard got sdhc support with an unofficial driver update).
A 32 gig card will work just fine with the Play.

I heard there's problems with class 10 32 gig micros on android phones. Is this true?
i'm curious about this, some applications wont work with a class 2 speed sd.
sd or sdhc would do. you should be more worried about the speed. as for now you should think of either getting a class 6 16gb or class 4 32gb (if you could find one).

I have class 10 32gb, works fine on xperia play.
The only problem android has, is you cant format 32gb cards on your phone. But most, if not all cards come pre-formatted anyway. Otherwise you have to connect the card with an adapter to your pc to format it.
*edit
You can format 32gb cards on your phone, but it wont format properly and you will have issues. I did with my old phone, it couldnt scan the card properly and it would reboot while trying to scan.

now that's something
read most of the reviews: crashes and corrupts the files, some even only last within 24 hours i'll stick with the class 4 32gb for now
even with the sandisk 32gb class 2 cards, i already replaced 2 of them when they crapped out on me

haven't read anything about this. and the reviews for a kingston 32gb class 4 on the net has been great so far. but if this will be the case i might just go for a 16gb class 6
Ok, so I got a 32gb card, moved all of my stuff off my 16gb (about 14 gig) to my pc. Took about 20 minutes.
Put my 32 gig in, formatted it & transferred everything over.
Took about 3 hours & when I put it in my play it's saying there's 28 gig left & hardly anything I set to transfer has actually gone to the card ! ?
Do a full format and not a quick format.
Ive seen a class 10 32gb micro sd card for 50 quid, but im worried that its too cheap and might not last long.

Memory cards are very reliable IF you bought the original ones and not those unbranded fake cards.
I've never had issues with ALL my memory cards, from the SmartMedia, SD, MS stick and Compact Flash cards used in my Palm and Sony Clie PDAs, my DSLR and micro 4/3 digital cameras, PSPs and DSL and all the way to the microSD cards used in my smartphones and tablets. I purchased them all from local reputable shops and never bought any from online stores. Can't remember the exact figures but I probably had a total of 30 to 40 cards here in my house.
The problem I see is those cards that are found on online shops that are unbranded (anything not Sandisk, Kingston, Lexar, Panasonic etc are all semi-fakes). Just imagine that Sandisk the world's largest NAND Flash memory maker has yet to come out with a 32GB Class 10 microSD as of now and you can already find some smaller unknown companies selling them at very cheap prices since many months back?
Sometimes if a deal is too good to be true, IT IS too good to be true! Of course if you still proceed to get them due to their ridiculously cheap prices, the risk is all yours. For me, I just buy the originals at original prices and not regret it later, my data is much more important to me than saving tens of bucks.
For some reason, there are quite a lot of fake Kingston cards on the market so beware.
Various issues with the fake/unbranded cards are:
1. Reliability
2. On a 32GB card, you may actually get only 4 or 8GB storage, some tricks were added in these fake cards such that once you copied beyond the 4 or 8GB capacity, it automatically loops back internally to overwrite the oldest copied data.
3. Some 32GB Class 10 cards only had Class 2 speeds.
Another advice is that for smartphone usage, you may be better off getting Class 2 or 4 cards rather than higher class cards. This is because although the class 6 or 10 cards can have sequential readings and writings at their stated class speeds, in terms of random access of data on the card they may actually be slower than Class 2 and 4 cards. In other words, you'll get more lags using higher Class cards.
Here's a test I did with a Patriot LX Series Class 10 32GB Micro SDHC

You sir are correct! My Patriot 32gb micro class 10 lags alot When playing the FPSE the game lags too much but with the micro sd card that came with the Xperia play runs perfect I'm gonna return the card and just get a Sandisk 32gb class 2 from newegg.
Recce5
After doing a test of manually copying content to the card I believe I have fallen foul to buying a cheapo card covered by your point 2.
I've bought quite a few cheapo cards back from my old K750i & PSP days but this is the 1st one I've been stung with.
Live & learn etc !
