Hi,
I have bought a 32GB micro sd card from Sandisk, recently. Before I had a 16GB from Sandisk. With the new card I suddenly have a battery consumption in standby from 15 to 20% over night. Before 3-5%. I thought it must be something wrong with the card. I ordered a 32GB card from Transcend - and it´s the same behavior.
So, what is this?? It seems that with 16GB all is fine and with 32...
There are no active programs, no data connection and nothing installed on the card. I have formatted the card again in the device - nothing changing.
Put the card in your computer, copy all the contents off it, format it and copy them all back on. Don't format the card in the phone.
I had same problem with a Sandisk 32GB which was bought from a reputable reseller. Tried everything and in the end gave up and now live with a 16GB just fine.
Strange ........ I am now with Sandisk 32gb for 4 month and absolutely nothing changed in batt drainage ...... 5% overnight with all caches possible moved to sd.
Maybe depends on interval wm has to write to storage card ? email-att., update files? meaning that batt consumption is higher for each read-write cycle ?
This is what I have tried first: Copy all my stuff on the card and put it in the phone. Later I have formatted it in the PC - copy all stuff - put it in the phone.
At the end I have formatted it in the phone, without copy anything on it.
No change, the same behavior, whatever I have tried.

This would be logical, when there is something to write on the card. But I put the blank formatted card in the phone! No apps installed on it, no e-mail, etc. Closed all apps and no data connection, wlan, bluetooth, etc. Pure standby!
Now I am happy with ROM 3.14!
I have updated to ROM 3.14 and now it´s working! Power consumption for both cards 16 and 32gb is equal now. Seemingly it was a malfunktion in the 1.48 ROM in conjunction with 32gb cards.

i think the problem is that you have not installed the sd card hotfix from htc on your 1.48 rom...which is usually included in next versions of rom
"Update for HTC HD2 SD Card Storage Cards
This update for HTC HD2 allows the HD2 to properly read the amount of free space on a storage card, so you can take as many photos or videos as possible. It also enhances support for some sizes of storage cards."

Should not be the problem, because I had ALL updates installed on the 1.48 ROM.
Hi all,
I'm planning on a format of my SD card. Before I do so I figured I'd created a new thread here on the subject...
I use Darkstone1337's SuperRAM 1.5 Froyo build which works almost perfectly EXCEPT since changing from a 256mb data.img to a 2gb data.img I'm now getting the 'sleep of death', i.e. phone taking forever to wake from calls and standby often. At first I thought it was down to importing data from my previous data.img so I formatted and started over but I have the same problem with an untouched 2gb build.
So, if anyone has any suggestions on SoD and how I should format my SD card next (allocation unit size, etc.) I'd be interested to know. A couple of threads say Sleep of Death and the SD card may go hand in hand.
I find it very strange that I never experienced the problems on the default 256mb data.img!
Replying to my own post... I found that the Sleep of Death issue was down to my Class 4 MicroSD card, this one: http://www.mymemory.co.uk/Micro-SDHC/MyMemory/MyMemory-16GB-Micro-SD-(SDHC)-Card---Class--4
Write speeds were ridiculous... fluctuating between 0.25mb/sec and a max of 3mb/sec, which is obviously below the minimum standard for a Class 4 card. So likely faulty. I tested the card with h2testw which also confirmed the slow read/write speeds. So I've switched to a Class 2 which is averaging about 5mb/sec which is certainly decent for a Class 2 and best of all it's fixed the SoD problems! SuperRAM 1.5 is running great again, even on the 2gb data.img. I can also boot builds that for god only knows what reason were refusing to boot on the Class 4 card (like Darkstone's SuperRAM Sense 0.1)
Formatted my Class 2 to FAT32 with everything on default in Windows 7. No problems.
SuperRAM now only has a couple of seconds lag max when switching on from standby and perhaps 3-4 secs max when waking during/after a call. These issues are being discussed in another thread though and look to be hardware/kernal related so not an issue of the SD card.
Yes. but we did not know what is the best format for Andriod, I got 2Gbyte SD with my Samsung, it was formated as FAT, a 1.5 mbyte data folder of seesmic twitter client takes 24.8mbyte from actual desk space !, there should be a better format, I wanted to try the Fat32 to minimize cluster size, will check, if you have any details please share, thanks
Hi,
Just updated my HD2 to 7720 ( ) but it seams that installing apps is taking to much time.
It takes about 10mins for almost every app to install (some apps take about 3min) .
Just want to know if this is the expected behavior, or there is something wrong with my WP.
Regards,
You need to change your memory card. I had the same problem with Kingston 8 GB class 4 card.
I tried to get Sandisk class 2 card as recommended by others here on XDA. Could not find it.
Changed to Sandisk 16GB class 4 card and it is working smooth. Earlier one small app used to take ten minutes to get installed. Now it does not even take a minute for the same.
Yea try your luck with another card, my sandisk 8 gb class 4 card works perfectly, installs apps in a maximum of 20 seconds for the very large games.
My sandsik 16 gb class 4 was hopeless and slow, apps would crash and take ages to install.
So it really is just luck of the draw im afraid.
Thanks guys,
That was indeed the problem.
Bought a Samsung 16GB class 6 and now works just fine. About 10seconds to install an app.
Regards
hi
I face phone restarts once or twice a day
I have 200 apps including 4to 8 HD games
I have 16Gb class four SD card
During these restsrts if i remove the sd card then everything goes
Normal.
Should i go for class 6 memory card
Or uninstall more apps
I have 10Gb free space in sd
1gb free system memory
And 2 gb free phone memory
Wat should be done
Two restarts a day is not normal - only time I had that was with a very early ROM. Have you tried different kernel or ROM?
Are most of your apps on the SD card? Seems that there are some dodgy SD cards out there.
What I would do is backup all of the apps, reformat the card and then load your favourite apps back on to it and see how it goes. Do you use 200 apps regularly? Just use the favourites for a while. Also maybe try a different SD card?

am still with my stock rom
all the possible apps moved to SD card , i just use those apps once in 2 or 3 days
only 4-6 apps i use daily .
should i go for class 6 SD card , currently am using transcend , should i try someother brand , if yes which one
Transcend is good brand. I've used it and a few other commercial ones (don't want to advertise!)
I have a Class 6 and Class 10 (and a cheap Class 6 one that I think is really only class 4 - it plays up and pixelates on videos)
If you can afford it definitely go Class 6 minimum. (PS I used Class 10 interchangeably on my DLSR for HD videos so I know it works well)
I would recommend formatting the card from the device itself and try again. Even 500 apps shouldnt crash the sevice. I have found several root apps that can crash the device but normally it shouldnt happen.
Transcend are a good brand and I wouldnt worry too much about the card unless its damaged.
The phones can be funny at times about the filenames in tye root of the card and i have found corrupt videos and images can sometimes crash the media scanner.
If youre capable, try get a dmesg log and logcat which might be more helpful if the problem persists.
Hope you have more luck now.

Hey there o/,
Last month i switched from NAND to NativeSD.
+ more storage
+ easy to install ?
- sometimes really laggy!
& thats the point why I'm now writing to you.
First I testet this ROM:
[3.Nov.2012][ROM] NexusHD2-JellyBean-4.1.2-CM10 V1.2 [NativeSD]
and the first problems appeared:
z.B. "Facebook does not respond.Do you want to close it? (Wait / Report / OK)
Apps sometimes needs a lot of time to load
Sometimes when I press the power button the keys glow but noting happens
laggy / slow system
com.google.process.gapps (a few times I think)
I use a Samsung 8GB micro SD class 10 card.
I searsched some of the topics here and also the topic mentioned above but found nothing that helped me ... also I dont really know what to search for.
Any ideas?
Thanks in advance
the important factor for the sd card is not the class, but the random read/write of small (4k) blocks, , , in general, the higher the class, teh slower teh random r/w, so thats probably why your getting occasional lag.
Try it again with a class 4 or class 6 card if you have one, , if not, at least run some benchmarks on your card, see what figure it gives for random r/w

For high speed read/write SD Card only (Class 6 or 10). Otherwise you may get poor performance.
Please create a FAT32 primary partition with 32KB cluster size, then an EXT4 primary partition with default cluster size on your SD card.
Please visit NativeSD thread for more info.

Take a look at your 4k random write compared to the other scores.
Im only passing on what I've read in several other places,,,that overall, the small random r/w speed is important when running an OS. If you choose to not agree then that's fine, you SHOULD question it, then you should research it. If you find information to the contrary, then I'm always happy to be shown to be wrong.
No ... I dont say hat you or anyone else is wrong... but it seems that there are 2 opinions ... I checked it now with an class 4 card ... and it was even or more worse than before ...
Isnt there anyone else with that Problem? Testet the ICs now too and same Problem ...
Need Help!
Thanks to all that commented up to now!
The microSD-Card!
Hello guys,
I really need your help :fingers-crossed:
Its really not funny with such a lame system
Apps answers need a lot of time - often process xyz closed / no answer
Contacts (20) need to load for a long time (~5-10sec.)
Keyboard often needs a while to appear
Lockscreen sometimes not unlockable / black screen / no touch reply
Installed now differenet ROMS
8GB SD (Samsung Class 10 - Benchmarks (post above)!
About 10 Apps (exclusive preinstalled Apps)
Do you need more infos?
Am I the only one with this problem (slow / laggy System?)
Any Ideas?
Thanks in advance! :good::highfive:

As it was said before - NativeSD became very laggy when using slow card.
There is a recommendation to use class 10 cards, because they are generally faster. However 4k random read/write speed is almost as important, as sequential read/write speed (the second one is guaranteed by Class 10, the first one - random - unfortunately not).
So, you have to buy microSD card which is tested for sufficient random read/write speed, like Sandisk Mobile Ultra.

Okay thank you - mhh next time Ill check some more points - its incredible how many things are important - but okay ... quite funny
Hello,guys
I'm using Xylo's PACman1.1a,and I meet problems on my new SD.
The SD is sandisk's 16G,class10, I've tried to format it with SDformat...
I try to install ROM by NativeSD,but when i run the rom,and sometimes the phone can't be waken up from sleep,and sometimes many FORCE CLOSE notifications appear and the phone will enter the loading screen...
I tried to wipe SD EXT and all partion of sd and NAND,and reinstall the rom many times,but when i used the phone,the problems appear again
then i get the ROM installed back to NAND,and use LINK2SD to move the apps to EXT4 partion.And the FC issue is still there,and sometimes it will notify'SD has been removed',or 'SD must be formatted'or'the sd is empty',but everything looks right on PC
I tried to search solution of it,but found nothing...
Is it really the problem of'Compatibility'?The SDCARD can't be used on my leo?:crying:
or who can tell me how to make the card be able to use on LEO normally...
Any idea is welcome...
You are not alone
Hi,
I am using Native SD. I specially bought a Samsung 16BG Class 10 card.
I installed latest Tytung JB Rom.
The interface is incredibly smooth. Swiping from one screen to the other is amazing. Scrolling in a liste (like parameters) is also very smooth. Games are running ok. So I should be satisfied!
I am not because I have the lag issue. By lag I mean that I sometime can wait more than 10 seconds when going from an app to another. Maps can take ages to start but not always. Instead of complaining, I prefer to mention what seems to help a bit:
- format your SD with EXT4 in recovery mode. I formated in EXT3 and converted it to EXT4. The performance was awful. Helps a lot.
- reduce the number of running process in background to 2. Helps a bit.
- close all apps you don't need running. This helps a lot!!!
I tested the speed of my SD card with Antutu and I am reaching above 10 MB read/write with no overclock. This is more than the speed of NAND. So the speed should be ok.
There's something we are missing but I don't know what yet.
To do:
- I will investigate the IO Scheduler. I hope it will make a difference.
- I will test PACMAN Rom
Okay - here the first things I detected up to now:
1st - What is this damn hat for?^^
2nd - The Camera isnt working really fine - pictures are ooooookay ... but I cant see the surrounding I want to shot - becuase Ive got a bug-screen ... something like stripes and so on ...
3rd - Speed is more or less okay
4th - Sometimes long "wakeup" time ...
5th - Nice keyboard
to be continued ...
Hi,
I am using NativeSD as well and I experienced the following for SD-Cards:
With my first card, a Transcend 16 gb Class 10, I had a lot of apps breaking down and hot reboots from time to time. This was the same problem with all the nativesd roms.
I decided to buy a different card because people on other threads said that Class 4 and Class 6 cards might be better than Class 10 cards for nativesd because of one important factor:
the 4K "random read/write" values
I finally decided to buy a Sandisk class 6 32 gb, but they sent me a sandisk Class 10/ UHS 1 instead
I tried anyway and my overall experience is a lot better now (except for some hot reboots once in a while)
I tested the 4K random read/write of that card on my computer with crystaldiskmark and achieved the following values:
Transcend 16 gb Class 10:
read: 3.9 MB/s
write: 0.020 MB/s
Sandisk 32 gb UHS 1 Class 10
read: 3.328 MB/s
write: 1.081 MB/s
My old Sandisk 2gb (don't know the class):
read: 3.154 MB/s
write: 0.014 MB/s
This result confused me a little bit. Is it possible that random write is so important?
In one thread they mentioned the Patriot Class 10 16gb to be very good.
So I would suggest to try different cards or search the forum.
Maaaaybe someone else has a card which enables him to have a super smooth nativesd android.
If that is you, reader, please tell us
Greets
Some figures
It seems from different sources that the type of SD card seems to matter. The class is not enough.
I just made a comparison test between a class 6 and a class 10. I used CrystalDiskMark.
Results:
**************************Class 6 Transcend***************Class 10 Samsung
____________________Read_______Write____________Read________Write
sequential_________15.2MB/s____11.04MB/s________19.8MB/s____17.66MB/s
512K_____________15.10MB/s____1.08MB/s________18.40MB/s____1.164MB/s
4K________________3.79MB/s____0.018MB/s________2.67MB/s____0.017MB/s
- For big files the class 10 is quicker. But when the files get smaller the class 6 becomes speedier.
- Both cards have a very bad 4K write performance. I suspect, the lag is coming from there.
- In this case, the real life experience is that both cards operate the same way: lags!!!
I found a review of the Sandisk Ultra mobile. The 4K write speed is more than 100 times faster than my cards. But the sequential write speed is less quick than my cards. All micro SD cards are not made equal! Guess what? I just ordered one. I will come back with the results: the benchmarks and the real life experience.

Thanks for this. It made me think and check out the problems I had. Very poor performance and all kinds of apps and system processes just aborted with error messages. It wasn't even possible to actually use the hd2 anymore. I kept pressing 'OK' on all the errors. I checked the 4K write speed of SD card I used for NativeSD and it was 0.006 MB/s. I guess that's the problem. By the way, it's a brand new 16 GB class 10 SDHC of ICIDU (icidu.com). It's a darn outrage they call this a class 10 (I know the classification is based on other parameters)! I've just ordered a new one from sandisk, this time not so cheap. Hope this will be better. Will let you know if that improves the situation. In the mean time I switched back to NAND with DataonExt.
Is there anywhere a really helpful thread with SDcard - recommendations?!
Ive searched for it and there are threads where they post the differnet benchmark-results ...
Yea I can check that "Half-a-million"-Posts too - but isnt there a list like ...
1. XZAY [r/w 4k - ~3 / ~ 1.2] - tested by (Mustermann) ... everything smoooth ... blabla ... [[20€ at amazone ... ]]
