can someone please help me?
I have tried many builds and they are all unusable for me when they are using SD partition.
Disabling it makes it usable again but no user space!
I have tried CW method of partitionig and GParted but always same result
My SD is Class 2, don't know if that is problem... tried many times to format it... tried many NAND ROMs.
Please help!!!
Brand, size of your sd card?
What format? Windows?
File system used in ext partition of sdcard?
Try a HDD benchmark test on your SD card. If sustained write is less than 2mb/s, then you want to use SD Card Formatter 3 with ERASE FULL (ON) and RESIZE (ON), if still slow, time to buy a proper sd card.
i noticed it by myself. got a 16 GB class 2 SDcard and since NAND-roms its really messy, changing the screens by sliding (stuttering - and gets worse the more apps are on it), loading apps are much slower than with SD-roms.
i ordered a 8 GB class 6 SDcard last friday, hope to get it tomorrow. will check it out with a fresh format and install asap. will come back and post my experience.
It's Kingston Class2 16gb.
First partition is FAT32 15gb, and second is 1gb EXT3 (also tried with EXT2 & EXT4).
It's strange but I remember that SD builds were much generaly faster (thats not the case when I turn off this partition).
Here are results:
Read 10.130 MB/s
Write 2.163 MB/s
I think they are good for Class2.
Any opinion is welcome!
Eww.. Kingston MicroSD.
You're right, their speed scores are pretty good. Stuttering is usually caused by slow reads, writes don't cause stuttering, except mainly when installing apps. Your card isn't corrupted, because the speeds are exactly on spec.
Well, the first few days of using ext partition on SD card for A2SD+ is going to be slow, till everything is written on the SD card, then it speeds up considerably. I recommend, try using it for 2 days, and see if you can't stand it.
SD builds already have everything in the SD card, including data.img where userdata is stored. However, with A2SD+, everything is in the NAND, but the application will move to SD Card ext3 partition, at the same time the Dalvik is also being moved there too. So yah, it can be slow, until everything is done scooting over.

Hi everybody,
I have a problem with my sd card.
I have a 4Gb transcend 150x card in my G4 prophet (s200) and reading is so slow.
Here i post a benchmark done by sktools:
Storage Card (write) : 31.75 Kb/sec
Storage Card (read) : 798.18 Kb/sec
I think reading time is so slow.
I have spanish qtek rom 2.20 and test was done using sktools 3.1.1
I have formated the sd in fat32 using computer sd card reader, but nothing goes better.
Any ideas on how to fix it?
Thanks in advance.
umm this is just a thought but have you checked the partition?
thats usually the end of most problems regarding SD cards.
What do you mean whith checking the partition?
I have formated the card twice one with panasonic formater
Best.
no check and rebuild the partition, formatting wont do much if the partition is corupted.
get something called Partition manager you can get a demo version that will do it. use your card reader and delete the active partition (remember to get your info off it first) then reinstall the partition format and mount the card.
see if that helps
Thanks very much, it seems that partition is ok and i also tried another memory card with the same results.
Could you please do the same test and tell me your results, rom version and memory brand and size.
Best.
So all i want to do is take everything off my 4gb sd card and use an 8gb sd card so that I have more storage space. Everything works great as is, and I wanted to keep everything as is. Just need more storage space. I've looked through the forums and haven't found anything that addresses this process. I am running CyanogenMod 7.0.3 w/a 4gb sandisk micro sd card. How do I copy so that it boots just like my 4gb card???? Thanks ahead of time for any help.

I recommend just writing an image file with winimage. Then writing it to a 8gb card, then using Easeus Partition manager to expand the last partition to full 8 gb.'
Do you boot from the SD card or eMMC?
If it's the latter, just copy the contents of the old card to the new one.
If it's the former, I recommend a fresh install; use a backup program (MyBackup, Titanium Backup) to back up your Apps and Data and then restore when you're done with the fresh install.
I'd like to do this as well.. in response to previous reply.. there are 4 partitions (boot, 2 other and last one with your data) do I have to create 4 different images with winimage or just for the first boot partition or does the winimage creates the image of the whole msd card?
The winimage will create a 4 gb image of your card on the 8 gb cards including existing partitions. What you'll need to do is get the largest partition to expand to the whole card. Assuming that the 4gb install on SD is the same as an 8 gb install if you did it fresh.
If the partitions are set different for 8 gb on a fresh install, you're better off just doing a fresh install and use titanium backup as the other guy said.

That's a good point, the Size-agnostic SD installer uses different partition sizes for everything except the boot partition depending on the size of the card.
I tried winimage first to see if it even worked. Which it didn't. I didn't try to expand the existing partition. It just booted as a normal nook. You would think this would be a easy process but.... Lol, always new challenges. Guess that's why I enjoy doing this.
Well I tried yet again w image, expanded the partition. Still. Didn't work. I must be missing something. How hard can it be to make a copy of a bootable card? Must b brain dead today! Any other thoughts? Thanks!

I have done this several times, and I recommend downloading easus todo backup free. Then place both sdcards in a card reader, run todo backup and just copy the 4g to the 8g and expand the fourth partition right there in todo.
This applies especially if you want to copy to same size sd's, as you will not run into the usual image sizing issues.
Hope this helps
I don't know what you're doing wrong. before expanding the partition, make sure the sd boots, if it doesn't, then there's a problem with image being read or written as opposed to the partition.
I also had a problem with a new SD card not booting that I fixed by using the nook (that is the core nook OS) to reformat the card, then put the image onto the SDcard (shouldn't have changed anything as far as I know, but it did anyway).
Ok I tried this and it worked flawlessly. Used win32diskimager to "read" my 4gb sd with cm7 image. and then used "write" to 8gb sd card. It cloned 4 gb original image with 4 partitions and one unused partition of 4 gb. After that used easeus partition manager(latest version) to format unused pattition to fat32 and then merged with last partition of 2gb (move/resize) ..so now I have 6 gb of data partition which i can use to transfer files or move apps from nook's internal drive. The new 8gb card with cm7 image booted without any issues keeping my original settings of 4gb. One thing to mention that somehow it did not work on one pc with windows xp (kept getting write error on win32diskimager program)but worked on my laptop with windows 7.
That is exactly how I have done it in the past as I described in my first post. I don't know why a person would have trouble with it unless there was a format issue (i.e. ntsf, etc).
My HTC HD2 works with my Transcend 4 GB microSD card, but it won't android won't boot up with my 8 GB Verbatim microSD card. Do I need to format it or something? Thanks!
Are you sure you have the correct set up ? (Files are copied to their destinations)
Try to format it to FAT32, and try again.
I`have just formated it to FAT32 and still the same problem. What files are you talking about?
PS: Sorry to bother you with "stupid" questions, I am pretty noob in this
I have read that Verbatim SDCards can cause problems in the build; booting or running, SanDisk is your best bet, but you may still be able to get it running,
Im not a dev; just brought SanDisk as a result of this,

It depends on many factors. Which Android Rom do you want flash, does this need Ext 3/4 Partition on the SD Card ? Do you have flashed the right partition size ? Read the installation instructions of Rom you wants to flash, there you mostly find all information.
Are you talking about NAND or SD? If NAND, make sure the ext partition is set up correctly, as this is where a lot of the apps are stored. If SD, then I would assume you know how to install an SD build so it could be a problem with the SD card being incompatible as alex.odell.2011 said.
I've had similar problems sometimes with my SD card; my HD2 wouldn't boot unless I took the card out then put it back in once it was booted. The only thing that I thought might cause it is something CWR related on the SD card, since I had used it in my Hero and Droid 1 as well to flash ROMs to them. It was a class 4 16 GB Sandisk, if that helps at all.
I was going to upgrade my rom to the new flexreaper rom and i figured i would partiton my sd card... but when i did it seemed to happen a little bit quickly.. so i checked my sd card and all my data was still there (therefore it did not wipe it) which makes me think it was not partitioned.
Also when i hit partition sd card - i picked 1024 for ext size (i have a 16 gb sd) and 0 swap - then partitioning sd card and done appeared almost at the same time which puzzled me...
can anyone tell me if it is actually partitioned or not or is it even worth it to partition a sd card on a tablet?
Thanks.
Hi,
I wonder if someone can help me, I've got WP7.5 install as a NAND installation, with Android 4.0.4 as a SD installation. Both work brilliantly, although I do have some slight problems.
Android won't detect an SD card installed, so I can't use some apps, that require an SD card to be present.
Does anyone know if there is a fix for this, surely I'm not the only person in this position.
Cheers
I'm guessing it's because your SD has been formatted specially by WP, and Android can't read this. Your FAT32 partition is probably too small for anything to be stored in it.
The Fat32 partition is 1.6Gb.
Is it worth making that bigger, or creating another FAT32 partition?
Cheers
Hmm, I'd guess that you wouldn't have any more than 200-300MB free on your SD as read by SD Android then. I don't know how much an SD Android build takes up but the data.img is at least 1GB of that. As for increasing the partiton/creating a new one, I don't actually think that's possible without losing your data is it?
Hi,
Thanks for your help.
I'm not too fussed about losing anything...
Here is what I have just tried without any success.
I have a 8Gb card partitioned like this.
1.*Gb
Primary, FAT32, (Android SD install)
2Gb
Primary, FAT32, (My hope would be that Android would see this as the SD card)
4Gb Other (WP 7 partition)
No luck unfortunately, any ideas?
Cheers
Are you sure you're using an 'unlockable' WP7.x ROM? If so, try formatting the storage card to normal and flash a Android build, see if it utilises the memory card like normal, if it does, then I would say that you're doing something wrong when setting it up.
Just double check each step of a tutorial (example: this one) twice and hopefully you'll only have to flash one more time.
Why do you have 2 fat 32 partitions ?...just use one fat 32 partition..in regular sd android....data image is used as internal memory and fat 32 part as sd card
I believe your second partition is not being recognised...make only one fat 32 partition you don't need two
