about micro sdhc card classes

hi guys,
i have searched forum, and realized that this is asked, but there is no clear results yet.
some people say get higher speed even with comparison to lower classes. and some people share their writing speed with adaptor, not on hd2.
i have sandisk 8gb class 2 sd card. and planning to replace with transcend 16 gb class 6. and if i will replace i will do this only for music tab. because its slowness drives me crazy.
anyway, what do you say guys? do you recommend me to buy new one? and can class 6 sd card owners share their opinions? but please, in terms of hd2, not adaptor speed.
thanks

I have a class 2, and to play graphic intensive games they have to be installed on the phone since the class 2 is too slow. I don't have a class 6, but I would think it would be more than enough for what the phone does.
My music was loading up slowly too till I put them in the correct file structure: Music/Artist/Album/XX.mp3
Also, I've noticed the phone performs better with .mp3 files rather than .wma or something else.

are you saying to put all music files in that directory.

have u tried formatting ur class 2 sd card to fat32 format with 16kb cluster ? Do a full format if u haven been using 16kb cluster. works for me. dont have lagging over at music tab.
im using 8gb class 2 card given stock.

Create a folder on the SD card called Music Then a folder in there for the Artist (Madonna, Jay-Z etc.) and another folder in artist for their Albums and put the mp3 for that album in there. So you'll end up creating a bunch of folders for each artist and each of their albums.
So your file structure on your SD card would be: Music/Artist(name)/Album(name)/MP3
This sped up my music tab considerably. BTW, if you use Windows Media Player or DoubleTwist to sync music, they will do the same thing and put them in the file structure I mentioned. Make sure they are mp3 files, I had problems with wma.
Hope this speeds things up for you guy's, like it did for me.

first of all i want to thank you for your replies guys.
@pool7979
what is 16 kb cluster and how can i find out whether i am using 16kb cluster or not. secondly what is full format?
thank you

For me, going from the stock 16gb class 2 that came with the phone to an 8gb class 6 made a huge difference. I have garmin mobile xt loading from the SD card, and program start up, address and POI search, map display and redraw is tremendously faster. Picture and album browsing is also much faster. I'm thinking about getting a 16gb class 10 to see if it'll make even more difference.

Take a look at this thread as well.

Your 8Gb may be formatted differently to how your 16gb was.

ok so basically, the higher the class, the faster the card ?.

hi sorry for late reply. what i did was insert sd card into pc. thrn right click format. from there i can set what cluster size it is . i think its something to do with.how data can be arranged/store in terms of size setting. i once read using 16kb seems to be the most optimum setting for winmo. seems to work for me.
to me class dun really matter for mobile phones as reading and writing on card are not that intensive. i would rather use a class 6 on a camera or act as usb thumbdrive instead with portable reader.

class speed

Basically the class rating means the minimum speed of the card. Class 2 must have a minimum speed of 2Mb per second, class 4 -4Mb, class 6-6Mb class 10-10Mb.
With a good quality card, the actual speed can be many times this, so with some makes, you will see an advertised speed ofup to 32Mb per second for a class 6, but in normal use the maximum is usually just under 20Mb per second.
So you may think a faster card is better, but this is not always the case. Just because a card can read at 20Mb per second, this does not mean a mobile phone can transfer data to or from the card at this speed. These sort of read/write speeds are designed for high end digital cameras.
A mobile phone does not need speeds this high, even to watch HD video. So anything above a Class 4 is a waste.
It is much better to purchase a good quality branded class 2 or 4 card.

or you use a software like the free/donation ware mp3tag. it will handle all aspects of working with mp3 tag's. i change the file structure of my 500+ mp3 files, from 'all in one folder' to the folder sorted format xeebot mentoined, with only a few mouse clicks.
and i can confirm that this speedup mp3 handling alot, music player is ready in 2-5 seconds after selecting the tab (before it taks up to 30 sec. and more).
another good program to prevent freezing and hanging of music tab is mp3val (also free/donation ware). it check your mp3 files for errors in the filestructure itself, and fix them if possible.
the definiton of the class/speed of sd cards can be found at the sd association website. the problem is to know what speed the controller of your device can do!. its useless to have a class 6(mb/s) card when your controller in the hd2 only do 4mb/s speed. and as far as i know htc makes always a big secret of facts like that .

[Q] Files on ext SDHC larger than 4gb?

I want to put some movies on my SDHC and the internal, but I can't copy files over larger than 4gb. Is there a workaround?

Convert your files to something more appropriate for a portable.
480p screeen resolution, so no need for 720+

It's a limitation of the filesystem the SD card uses, fat32. You'd have to format the sd card to use a different filesystem AND flash the kernal so that it can read said filesystem.

I know, but since I had them already encoded, and sitting on my hard drive, I'd just throw them on there. I'm all for a kernel that will read NTFS formatted volumes. Thanks for the replies.

Why would you have bluray size movies on a hard drive when they won't look any better (because you're not playing them on a bluray player)

NTFS is not one of the current possibilities, plus even a desktop version of linux has compatability issues with it. I don't know file size restrictions, but current kernels you can flash will support ext2,3, and 4. I think someone is also trying to build a kernel for yaffs.

I backed up all my Blu-Ray's to .mkv files in 720p. That way I can have them on my HTPC that's in the living room. Also, my kids have dirty little hands, and I don't want them ruining my originals. My desktop PC gets regular movie use too. 24" 1080p ASUS monitor. )

Galaxy Note also has this problem. How can I copy a video more than 4G. Note support 720p.

EXfat would be a godsend if some one wrote a kernal supporting it ..

u guys can always split the files in smaller parts, i use mkvtoolnix(freeware) to split mkv files into multiple parts while leaving the original untouched and doesnt take a whole lotta time depending on file size

MKV files bigger than 4Gb? How to split them to copy into FAT32 4Gb size-limit SDcard

I don't know if it's already been posted or not.
You know that our SD cards (internal and/or external) is FAT32 formatted, so the FileSystem size limit is 4Gb.
This means that if you want to copy on your phone one file .Mkv bigger than 4Gb you can't
Some users have tried to split the Mkvs in several files less than 4Gb using tools like MkvMerge, but the Phone doesn't recognize the files outputted.
But if you split the file on a Linux OS (Ubuntu i.e.) the files generated works perfectly on the phone.
I have tested it on Ubuntu using MKVMerge, starting from a 4,8 Gb Mkv file splitted in 3 files (2Gb-2Gb-800Mb), files copied on the phone and played perfectly with the default Video Player.

There's a much easier way as well, though I've only tried this once:
If you connect the phone in Kies mode (in the usb settings) and it connects properly you will get a "GT-I9000" Device show up in my computer instead of the standard lettered drive under "Devices with removable storage". It seems that you need to have Kies running in the background (with the icon in your system tray) but not fully open for this to work (not entirely sure on this as Kies is finicky). When you double click on the GT-I900 device in my computer you will get options for the internal or external sd card (assuming you have one installed).
If you copy and paste a file onto either of the sd cards using this method, it uses the Kies background service to check the file. If it detects a media file that might not be supported it will give you a warning which you can choose to ignore and copy the file anyways. I've found that if you copy a larger than 4gb mkv it uses the Kies service to split the file and put it on the sd card automatically. This takes a while as it has to split/convert the file and then write a fair amount of data to the sd card over usb.
You may be confused when it finishes as it only shows 1 file, it is smart enough to hid the others. The size of the file seems to be the amount that the original one was over 4gb (ex a 4.7gb movie will show as 700mb), however if you check the space avail on the sd card you will see that it contains the full movie. I transfered a 4.7gb 720p rip of "Tropic Thunder" this way to my phone and it played just fine on the samsung video player.
Let me know if that works out for you, I havn't seen anyone else try this.

how about formatting the SD card as Linux EXT3 or 4
the use smb mount, so when it does the mass storage mount to windows you can simply drag and drop, without having to cut any video into 4 GB chunks due the FAT32 limitation?

Wow if this is true it is some pretty slick thinking ahead by Samsung both on the phone and PC side.. I think I will try this just for kicks, have a 6 GB MKV right here.
EDIT: Could not wait any longer... thing was maxing my CPU for 1/2 hour. I am pretty sure this is doing some kind of trans-coding.

This is exactly the test i would like to do, do you have already tested this way?
But, atm, i haven't any SD card to use and (most important) i would like to know if after having formatted in i.e. ext4 i will be able to re-format in Fat32.
And however, do i need a particular Memory Card Reader to read one ext? SD formatted card?

Yea just make sure that it's 720p and not too high of a quality level.. I know it doesn't do quite all MKVs as the format is not yet entirely standardized. It seems to handle 4~5gb 720p mkvs just fine though, they just take FOREVER to transfer.

I don't know that the phone would accept a file system other than fat32? Would be easy to find out though.

i have some videos that are larger than 4G
i'll definitely give it a shot to test the Linux partition theory.
I'm almost positive it'll work, as the "Lag Fixes" solution all uses the EXT3 and EXT4 partitions anyway.
but in our case we want to use it natively for video playback, and be able to mount it when we want to use it with Windows
re: question about formatting back to FAT32 after EXT3
Yes, it's possible and safe to do so.
As soon as i have more time in my hands, i'll give this a go, unless some one beats me to it (some one with more time on their hand)

Haha yea it's software encoding, I think having Samsung encode it so it could run on your GPU would be a bit too much to ask lol. A 4.5gb movie took my quad core about 25 minutes to encode and then transfer.

u can download mkv smaller than 4gb..and graphic will be still great =)

Its not just movies I want to be able to place on sd card. I can't split those files. And I don't want to convert existing mkv files to a lower resolution, spend time on that.... its not a quick process to compress the resolution. I much rather be able to copy what i have now to my phone, instead of having to modify. ...

I use http://www.bunkus.org/videotools/mkvtoolnix/
You can set the file size and even remove unwanted subs and/or audios.

I have mkvtoolnix and have used it. Thats not the question, but thank you

Anyone knows?

not losing hope. It will be useful for others, I am sure.

compressing the file would help
as in making DVD sources with less channel or less quality can drastically reduce the file size without too much sacrify to HD quality
say for example choose 720 instead of 1080
2 channels instead of 6 channels
or even if you keep it 6 channels make it 160 instead 320, or maybe drop it lower to even 128 kbps
use 44 instead of 48
use 25 fps instead of 30fps
etc...

[Q] Yet another n00b thread; new Nook owner, very lost. tl:dr it for me?

I know there's a lot of threads like these, but everything I could pull up seemed really out of date, or didn't have the information I need. The Wiki was good, but just gave a list of all the builds out there, and I can't sort out which one is currently best for what. I'm hoping someone can give me some quick answers:
tl:dr: Have a brand new Nook Color. Video will be 95% of what it's used for, little to no web browsing or games. Would like to use it to watch movies/TV shows streamed from my NAS or off the SD card. 5% of use will be viewing photos directly off my digital camera's SD cards (using converters in the cameras).
Tell me what OS/Software to use. Most files are .mkv format, usually 720p.
Currently, I've got Nookie Froyo installed on the SD card, and after a lot of frustration of how the heck to actually get files onto the SD card while also having the OS on there, I found that bootloader NookColorUMS thing, which even though it seems like more steps than should be needed, has allowed me to copy files to the SD card with the nook connected via USB cable.
I'd like to have the OS installed internally, so I'm free to swap SD cards around to quickly move data around. Also so I can pull the SD cards out of my cameras, stick them in the nook, and browse the photos.
Currently I'm using Rockplayer Lite, which plays the 480p files fine, but craps out trying to play 720p. It also is very annoying in that it it has no back button in the UI that I can figure out, so you have to use that tweek to force the status bar to always be on top, which is annoying. If there's any way to get the stock player to play the files, that would be best. I know it should be possible, my Samsung Moment plays all these files naively with the build-in movie player. But the Gallery player won't play them on this version of Froyo that I've got on here.
My questions boil down to:
-What OS should I use if I'm going to go through the trouble of figuring out how to install in on the internal memory?
-What's the best video player/codec pack?
-How do I browse/play files off my shared drives on my computers and NAS unit?
Thank you for any answers you can give, or any directions you can point me in!

Hope this helps.
-What OS should I use if I'm going to go through the trouble of figuring out how to install in on the internal memory?
CM7 - try phiremod nook
-What's the best video player/codec pack?
I've been using handbrake to convert all my video to MP4 using these settings.
-How do I browse/play files off my shared drives on my computers and NAS unit?
PlayOn works pretty good. Depending on the source video type i get some sync issues.

Easiest install method
#1 Install Clockwork Recovery Mod to internal memory from your bootable SD card.
#2 Drop your desired rom on the root of a non-bootable SD card
#3 Restart into Clockwork Recovery Mod by powering on with n button held down
#4 Backup!
#5 Flash zip from sdcard
Now as far as video... I think you might be disappointed. You are going to need to reencode each video for the nook to get best results.
I recommend Phiremod Nook 6.2

Thanks for the reply's everyone. I'll get CM7 installed tonight.
I'm REALLY hoping to not have to convert videos to be able to play them on the Nook. That was basically the reason I DIDN'T get an iPad, I don't want to have to convert videos into a specific format to play them. All of these files played fine on my Moment, I guess I made the mistake of assuming they'd work fine on any Android device.
Is there no way to just be able to browse a network, and view/play videos and pictures on them? It seems like it should be such a basic feature.
What other good video players are available besides Rockplayer? Or, how would I install additional codecs to get the build-in video player to work?

I think Vitalplayer Neon and Mobo player are pretty good for the nook.

TL;DR; ?? Reaally?!?
Not reading (repeatedly the same instructions over), being impatient and rushing headlong into things is the easiest way to muck things up. We're just lucky NCs are impossible to be permanently bricked.

CM7 latest nightly (n86 onwards) has the newest fix for audio and video, while being on the .32 kernel and have support for an Overclock kernel. Smoothest vid playback I've ever seen, without any mucking about in re-encoding in Handbrake, etc.

I use moboplayer. 720p vids are a touch-n-go, some are OK, some are not. But if the HW acceleration (of the .32 kernel) doesn't cut it, moboplayer has the soft-decoding option.

Just install, no other tweaking necessary. All extra files (mentioned in older thread abt this) have been in the CM7 ROM since n30s or n40s (or n50s, I can't remember really ).

[Q] can ds7 play .mkv?

I tried to put an .mkv movie on my ds7, and the windows or the computer, who knows, didn't let me do it. It said that the file is larger than the permitted, or something like that.
Oh, and I have an other question as well. Is there a faster way to put movies, actually files from the computer to the tablet than just copying it simply to the chosen directory?
Thanks in advance!

Since the format is FAT32 you can't put a file larger than 4gb on the SD... I may be mistaken... as far as file transfer you can learn to use ADB commands or something like SAMBA which for me both are faster than MTP

Okay, I see... and should I change its format to NTFS? I read somewhere on the internet that somebody changed his SD card's format to NTFS and it solved his problem. But I also heard something about that it's intentional I mean significant that it's FAT32... what do you think? And what would happen if I changed it and would go bad? Would it screw the whole SD card?

im not sure the kernel supports ntfs

u should split ur movie file to bring it under 4gb.
reformatting ur sd card to some other filesystem will render it unusable in the tablet.
u can try using an ftp server or stream directly from ur computer (like using vlc direct).
class 4 sd cards (the common class) ve max write speed of 8-10mbps, so cant go beyond it.

Thanks! Good ideas! I think I'll just split it to 2 parts, but the streaming through VLC is also simple. Thanks again! Btw, would you recommend me a program what I could do the splitting with?

You can try to put it on the Internal and use an app to play it. That's what I do.

I was trying to put it on the internal. But I think I have solved the problem. I got a player called Dice, and as it is said it plays HD videos perfectly. It really does play movies better than MXplayer, so I recommend it, especially for Tegra 2 tablets.
