Blank image files of wp7 partitioned sd cards - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

As everyone already knows the only real way to dual boot wp7 and android currently is via a partitioned sd card. However this requires needing two sd cards, one smaller, one larger. Because I only have a 8gb would it be possible to get a blank image file (one from a fresh boot without any special data) of a 4gb or 2gb sd card? If someone could upload them then it'd make the sd partitioning much easier.

[HOW TO] Get a smaller wp7 partition/bigger FAT partition

After a few questions I decided to write a TUT how to get a smaller wp7 partition.
Better: I tried to write a TUT
What you need: your sd card, a SECOND SD CARD with less storage, partition app for pc(I used EASEUS Partition Master 6.5.2 Home Edition), usb cardreader
1st step: flash wp7 with magldr when the SMALL sd card is in your phone or perform a hard reset with the smaller card when you have already flashed wp7.
2nd step: connect both sd cards to your pc and run the partition app.
Delete the filesystem of your BIGGER sd card.
3rd step: copy the wp7 partition from the small sd into the unallocated space of your big sd.
Now create a new partition(FAT32) of the rest unallocated space and convert from logical into primary partition. The drive letter must be set on your fat32 partition! Otherwise your pc will not find it. In front of your wp7 partition should be a “ * “.
I used 4gb and 16gb sd cards so I got 3.5gb wp7 partition and 11.5gb fat32 left on my 16gb card .
Sorry for my English
Hope it can help anyone of you guys and don’t forget to thank DFT for LEO70
Wouldn't it work to have 2 sd cards?... 1 for wp7 and 1 for android. Just make sure the phone is off when you switch them and make sure the wp7 card is in when you boot into wp7. I want to try that... have my 16gb for wp7 and my 32gb for android. Has anyone been able to boot android off sd with magldr yet?
EDIT: Oops, I actually posted this in the wrong thread. Sorry.
Hmmmm tried doing this but failed, I think it's due to my card reader only being able to read Micro SD and not Micro SDHC, tried doing it through magdlr usb was a no go, could change the partition but not wipe it, nice idea though, I'm sure many will find it helpful

[Q] wp7 rom chefs quick question

wp7 make a partition on your sd card using the whole thing. correct?
can you make it so when you install wp7 it only uses 8gb partion on SD card?
Then I would be able to boot ad from sd or ubuntu.
the only tutorial on how to dual boot wp7 and AD, you need a 8gb sd card. I have two 16gb SD cards
Any answers would be helpful
Thanks

There are a couple tutorials for partitioning your sd card to dualboot wp7 and android. There's a thread in this section and another thread in the hd2 android sd dev section. If the tutorials use a 8gb card as example, it doesn't mean you can't use any other size. I have a 32gb card partitioned.
And you can use magldr in mass storage mode as a card reader, but it will sometimes corrupt the file or card, so if you have no other card reader, use magldr, but if you can use a card reader, I'd go that way.

[Q] Upgrading from 4gb sd to 8th sd?

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).

[Q] Using Clockworkmod on 16GB SD Card

Hi,
I want to root a Simple Touch Glow and was following the steps using SD_2gb_clockwork0rc2.zip.
The trouble is that is designed for a 2GB card and mine is 16GB. Can I use it? If not, is there a version for the 16GB card or do I need to buy a 2GB card?
Thanks in advance!
Yes, you can always use a bigger SD card than necessary.
If you are writing an image to the card you may end up with the drive appearing as if it were a smaller size.
When you are all done you will have to reformat the drive to get it to be its full native size.
For instance, writing Noogie to a 4 Gig SD card will work fine.
When you are done, the card will appear to be only 70 Megs.
Just reformat the card.

As can SD Formatter, and the Nook can as well from the settings.

[Q] Use the SD card for storage "Android SD"

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
