Hi,
I'm trying to keep up with the thread on the development forumm but theres to mach going on there.
Can someone please explain what's that they are saying that the rom is locking the sd card and the tonight there will be another rom?
What all this about? whats the difference between the current rom and the new one?
Thanks
it locks the sd card meaning the sd can no longer be used as a regular sd card and will only work on a windows phone 7 device
yeah, at the moment, you have two choices
use the V1 ROM and be able to upgrade your ROM, you can install android still, you can not upgrade to 7712 / 7720 AND have access to your SD card UNLESS you lock the SD card
the second choice is use V2 ROM, this will lock your SD card from the start and enable updates to be much easier
Locking the SD card means that it can not be used at all on another device, Currently there isnt any software that can format the protected portion of the card, some hardware devices can format it, Some Nokia phones, some camera
Locking is actually very useful unless you want android on the same SD card
If you do want to use Android as well then get a second SD card and pop it in when you want to use it.
WP7 its self CAN clear a protected SD card but it will keep it protected, so you can reflash new WP7 ROMS with protected SD cards without any issues at all, but it will always be protected unless you use a Nokia type device.
You can also format a locked card using your wm6.5 on hd2;-)

No, it cannot. It says it is damaged on my topaz.
A buggered up partition table can be fixed with a propper format which is what 99% of people say "fixes" a broken card.
However, a "Protected" Card can not be formatted in this way, im have a chat with the SD association at the moment to see whats what, so far it is a software limitation on the PC that is stopping us clearing that data, in short if someone writes a program to do it, it will do it, the question is how!
can you guys see the partition on a PC partition app but not modify it? Or can you not even see the partition?

if a SD card has been locked its essentially unreadable in anything but the device that it was locked in, if you plug a locked (protected) SD card in a PC it will be detected in device manager but windows will not beable to access it, the SD association is a bit vague in their replys but apparently some OSs are able to format a protected card, MS isnt one of them unless there is undocumented flags that can be used at the command prompt, the best bet is probably Linux, I hate using Linux as a desktop but i do have it running as a VM server so i might give that a try a bit later
The funny thing is, its not complicated to do it (apparently) its just no one has really used the protected feature set of the SD standard
Also, (apparently, some SD cards use the protected area to store information other than the encryption key for the whole card, apparently this information might be used in read /write operations on the card, clearing the protected area to remove the SD card lock might have a negative impact on the cards performance.

Sorry, but it is confirmed. Windows Mobile 6.5 can not. Apparently Ubuntu does, I am testing!

Interesting. I did a few experiments and a whole heap of reading about this yesterday (Osx doesnt recognise the card either btw):
The card became locked during the update process from 7712 to 7720 during one of the many hard resets i did whilst installing the cabs (the sd fix cab was the last cab i installed). My mistake was not bothering to change the language from its default (English USA to English UK) so it would appear the card is also not only locked to a particular device but its language also.
One could test this by inserting the card, hard resetting and choosing USA as its language, however, it took 4 hours to get the device working to 7720 so im not doing that just yet; so i tried something else.
I put the encrypted card into my hd2, entered magldr and cleared the partition using services. I then entered usb mass storage and connected the device to my PC (win 7 x64). Whilst the card was not recognised in "my computer", if you look in camera&scanners in control panel, you will see magldr is recognised as a mass storage device but the device drivers for this fail to install properly. This is probably due to the "unknown" partition taking up the full capacity of the micro sd card and why it is not recognised by the PC hence it cannot be used for storage.
Unfortunately this also means no partition software will recognise the card, nor is it recognised in any digi camera, even after allegedly clearing the partitions via magldr.
I then had a thought would a nokia emulator work in unlocking the card? to which i havent researched any further as yet.
**EDIT** Apparently someone has decrypted and formatted a card using Ubuntu, im off to download and try it
**EDIT 2** not having much luck with ubuntu either, card not recognised........
same here, ubuntu disk manager (11.04 32-bit) shows sd card but 2.2 TB and can't format the drive or volume (i tried the same to clear mbr using magldr), ubuntu is not working
WEll, they havent been much further use, all they say is that is perfectly possible to do with software, the APIs have been there for years, its just that no one has ever really paid much attention to it, with the exception of Sat-Navs, professional Music gear etc.
Ive not had a chance to play with Linux yet but i would imagin that you need to think lower level than partition / MBR levels
From what i can gather from their cryptic responses is that when a SD card is setup to use the Secure feature, the device creates a key in the secure section, only that device can then access that section, the storage space on the card is then encrypted using that key, there is no way short of cracking the key to get access to either the secure section or the storage section. However, when you use an OS or Utility that makes use of the Secure protected area its possible to clear it, this would clear all the data obviously off the card, even disk analysers wouldnt be able to see it as it would still be encrypted.
What is concerning is that the Manufacturers have grown used to this special area and use it, apparently this area is used for IO operations, (probably some kind of cache or superfetch) this speeds things up by predicting what you are going to access next
What concerning is, if you have a class 10 device that as we all ready know uses methods to speed up sequential speeds to get that class rating, IF we manage to clear that protected area will the card be effected in terms of speed, conversly, could it improve random access speeds (WP7 essential) if its not farting around trying to predict sequential IO ops!

Of course you can update!
I am using V1 and have the 7720 build
has anyone been able to (in windows or linux) copy the partition on the card without modifying or formatting or anything? Just copying the partition to another card?

I'm going to try as well. If we can just get a recognition/copy to work, then we can do dual-boot again. There has to be some way to copy the entire partition.

read it again,
note the big "AND"
you can not dual boot Mango 7712/7720 and android on V1
you can not dual boot at all with V2
you cant copy encrypted partitions, it doesnt work that way, its not like making a encrypted folder, its on a much lower level than that, its either encrypted or its not, you either have Mango or you have Nodo AND android
I still cant get the Protected SD formatted, im wondering if its reliant on the card reader supporting those commands.....
Mm the secret I think is gaining access to the hidden part of the card that contains the encryption key. I'm still working on Ubuntu and have a lead to follow up on.
Your right about the droid dual boot, this isn't my intention so others shouldn't get their hopes up ;-)

Hey dear all,
I was one of the first one to install Yuki's Mango ROM...today I tried to unlock my SD card with a Nokia phone to no avail. Its asking for a password.
Whats the easiest way to unlock my SD card now?
So
you will use your sd card in another phone ?
I prefer miniTool partition wizard, it's easy, free program for windows.
Just plugin your sd card into computer, open this program, delete all partition, add new "Fat32", label primary, and all space for FAT32, then hit enter and plug out
thanks but the card is locked....how does my computer recognize it?
I have an old Nokia phone but it won't format the card because it says I need a password...a password that I do not have.
I need to completely delete everything on it or else my SD card is useless. I can't use it anywhere.
Your pc will just see, that sd card is blocked or sth.
But dont worry, just open the program.
Every time i change wp7 to android i use this.
Sry for my poor english

Just ignore password request and you'll get the option to format the card, just as simple as this mate
P.S. Another opportunity is to install DEV_STORAGELOCK.cab through the WP7-Update-Cab-Sender within Yuki's ROM and then choose to unlock the card
Thanks guys. For whatever reason my PC doesn't find it...and my Nokia won't let me format it. Unfortunately I don't have the Yuki rom anymore. Now it's on stock rom...maybe I'm doing something wrong ? :-S

So to check out wp7 on my hd 2, i put a new 2gb micro sd, wipe with task 29, installed magldr, installed xbox mod sp1 rom, used it for two days, synced with zune, installed reg tweeks on windows ultimate so that my hd2 is shown as a drive, copied some stuffs, etc..
Now i tried to install htc oem app cab through cab sender, successfully done, to use it, i reset my device from the about menu of wp7, rebooted, after the windows phone boot anim, it got nothing, other than the 4 dots moving all the time, i then removed the sd card, then reboted, this time, it boot up fully, but when ever i use the card, it will stuck on boot. So i put card on my comp using card reader, but windows cant formatt it, when i use mini partition tool, it says the disk is bad, i cant formatt the card any more, not with android recovery menu or wp7 or android, i tried to clear mbr sector from mag ldr service, it wont make things right.
I put card in some other nokia, samsung phonez, non have detected it. I am sure the card is not locked, as its a new one. Also was working for two days as i synced some music etc with zune.
Does this happened due to wp7 or the card is just dead? If it is due to wp7 how can i correct it???

format card with old Nokia phone if you cant send unlock sd cab
http://forum.xda-developers.com/showthread.php?t=1242071
Tried every thing, psp 1000, nokia c5, china mp4, cybershot camera, samsung phones, nokia phones. Nothing detects the card. My last hope is sd unlocker, which is a device( yap straight from china thats why we say - GOD CREATED MAN, THE REST IS MADE IN CHINA) used to unlock any sd which is locked, the device is just as small as a card reader, and dont even require any computer, if u have comp, u can use usb to power it, if u dont have comp u can use 9v pp3 batt to power it. Put the card in it, an led indicator blinks( ho it must be calculating 512bit aes encription!!!!) After 1-2 min it will stop blinking. And ur free to go.. the card will be unlocked.
The only draw back is the card will get formatted if u use it.
And i am sure if it cant do it, i will safely place the card in dust bin. Thank god i never went for my 8gb card to try wp7.
Wp7 owners must use this china dev... its an inevitable device 4 u guys..

Hi all,
I'm running the new DFT Ultrafruit ROM on an 8GB storage card. Unfortunately, I forgot to unlock my 16GB card while running Yuki.
So, given that I have an HD2 running Ultrafruit, is there any way to unlock my 16GB card without finding a Nokia device? And if not, are there any stores with display devices in the Philly, USA area that I could snag one for a few moments?
Thanks,
Ben

I will resort to that if necessary. I'm trying out shred on a linux box since I have direct access to the card in Linux. I will of course post if it works, but it takes a LOOONNNGGG time to write random data to a 16GB card.
Thanks,

What you need is a program that formats the Secure section of the sd card, unless that is cleared the card will always be "locked" no matter what you so to it, this is partly why so many folk mistakenly believe their SD card is dead, its not. The problem is that very very few devices and to my knowledge no software actually supported the full sd spec and thus cant format it. The section of the sd card that holds the shared encryption key is outside of normal storage space, which is why all programs to my knowledge won't format it. its very clever an im surprised so few have used the spec till now, personally, I'd rather keep the sd lock, with pin lock on there is no way of accessing my data, even if you pull the sd card out

for example: I'm using Mini Tool Partition Wizard. Works perfectly
Does that support the secure section format? Another very easily overlooked point is that the card isn't locked at all only hidden because of an unknown file system format, in such cases windows its self can fix it using the computer management mmc. If it does do secure section format than that's a very useful find....*heads off to check =)

Hi,
After a long history with successful 6.5 updates I thought I'd try WM 7!
I've read the storage card posts and tried a hard reset both with my card and without but always get to the same Storage Card not working error.
I don't have a Nokia to reformat my card but have tried reformatting on the PC.
There is a bit I haven't been able to follow using magdlr 'services' option - how do i stop WM7 from booting and get back to the magdlr menus?
Some advice for a noobie please - don't want to brick my phone but not that fond of the Storage Card Not Working screen either!

I'm sorry to hear about your issues. The micro SD card you've fit in your phone is too slow to cope with the constant read/write imposed by the OS.
The card you've used is unusable unless you unlock it by sending the unlocker cab to your device, unlock it, then format it on your computer. You could also format it on a symbian, nokia device.
Unless you mention the specific part number of your micro DS and brand, I can't help you further, with regards to compatibility, however, some models are proven to work flawlessly on WP7 powered HD2. ( such as sandisk 32 GB)
Make sure to further research, and hopefully you get this sorted out
only old Yuki (Back to the future) ROM lock cards...
all new ROM's not lock cards and unlocking or formatting with nokia device not necessary
if card not working: simple, not supported.. you must buy new card...
you cant brick phone... just read my install tutorial from signature if you something dont know...
Thanks for advice.
For benefit of others the symptoms I had were down to initial install. I needed to use Magldr to free up last 24 of nand memory and then reflash. Now all working.
As ever none of the stickies quite cover everything, but your help and another google session saved the day.
Thanks to the developers! WP7 giving my phone an all new feel.
