Memory clarification - Windows Phone 7 General

I have read so many articles and some of them conflict with each other. I was hoping to get this cleared up. It is my understanding that the windows phone won't have removeable storage like the other WM, android, etc phones do. But I was also told that if the manufacturer designs it, the sd card internal can be replaced but when you do so you will lose all of your data and settings. Is this correct? If so, then you could put a larger card in before you setup your phone and then you would have room for multimedia and you don't have to worry about losing everything. Can somebody clarify this for me?

Technically "yes". But until some actual phones are on the market, it's very hard to answer.
However, the only data you'll only have local copies of on the SD card, is your multimedia (music) data. Everything else, including settings, will be "in the cloud", so it's not a real issue to reset the phone.
But again, we need information about the specific hardware releases for the public, before the subject can be 100% clarified.

Thanks for the info. That is what I was wanting to know. If I am going to use the phone as my pmp device as well, I will need the storage for my audio/video.

I believe they are supposed to have a minimum of 8gb of storage. This is supposed to be one of the areas that OEMs are supposed to take advantage of to differentiate their products. Give their handset appeal by tossing in a 64gb sd card.
I'm not seeing a reason you wouldn't be able to pop it open to put in a bigger card, but doing so will most likely void the warranty on the phone.

It will vary. Some will probably use internal microSD cards while others will use discrete memory chips. The minimum is 8gb. If the manufacturer does use a SD card, it is unknown how easy it will be to replace. I've seen text in the resources in the emulator saying that you must replace the original card that came with the phone. We may have to come up with a utility that formats the new cards in the way the phone needs.

How many MB can be stored on the XDA IIs?

I'm interested because I would like to use my IIs as an MP3 player and camera on top of the basic functions.
I am afraid if I store more than a few MP3's, pics and misc. files on it, it will run slowly. Furthermore, I honestly do not know the memory capacity in regards to storage space on the device.
It also has an SD card (I think), but I have no idea how much storage cap. is on it, since it is an all black, blank card and I can't seem to access any info on it in the interface.
Is there any way for me to know how many MBs I can store on my XDA IIs?
Help's appreciated.
You sure it's a real card? It may just be a slot cover. You should be able to use a SD card of just about any size -- I use a 1GB, but there are now 2GB (and maybe 4GB soon) cards.
yep, it's slot cover...
Damn, how oblivious am I... it is indeed just a slot cover.
But I can get insert a memory card in there, huh!? That's great, I guess that takes care of my storage problems.
Thanks a lot mate.

XDA Graphite won't recognise memory card

I've had my O2 XDA Graphite for more than a year now but only just decided to get a MicroSD card for it. However, I have plugged it in, and when I go to file explorer I cannot navigate "up" from the device to get to the memory card, also when i try to download files I cannot save it to the memory card.... Can anyone offer any advice?
I thought it'd be like my previous smartphone where you just plug the card in and it should work. Occasionally the phone would not recognise it, until i rebooted the phone and then it would see it again, this time I have to remove the battery to insert the memory card, and then power it up with it plugged in and it still doesn't recognise it.
Can anyone offer any guidance.
Many thanks
Only thing i can think of is you have an SDHC card which your Graphite may not be able to read. What capacity is the card? Greater than 2Gb then it is SDHC, less and more likely not.
this is the one I went with - it's not SDHC, just Micro SD - I didn't think that would make a difference? If I go with the HC one should that work (obviously dont want to waste another £6!)
That one is SDHC. The fact it is greater than 2Gb in capacity makes it an HC one anyway, i think. Do a search on here for the SDHC driver CAB. I've never tried it but its worth a shot. Can't remember where it is, don't be surprised to find it in one of the device specific sub-forums. It should still work.

SD Card Warning. Edit: there is a fix to this .

So I was in the same boat you are in. Nothing could read the card except for my Nokia n97 mini. It recognized the card as "locked" and prompted for a password. I bypassed the prompt and went to the file manager. From there it let me format the card and it is back to normal. See, Symbian is good for something after all!
PS: I tried the same process with an E71 and had the same successful results. All recent Symbian phones should work as it appears they can handle the encryption and password. The card is now happily back in my HTC EVO.

There are some people reporting that if you replace the sd card of your WP7 phone and then want to use it again for your pc it isn't reconsigned any more .
this mean that you can not use it and you can not format it (for the time being it is bricked )
lets hope someone knows a way to fix it .
edit : maybe it is wise to make this sticky for a view weeks .

correct. Once the card is formatted for the phone, it can only be used with the phone.
Huh? You cant even format it after using it on the phone? Maybe Windows will fail to format it but there has to be a way to get it formatted again. They can't brick your card.

No , you can't format the sd card any more after using it in your phone .
you can only use it on your wp7 phone .
and that could be real expensive if you brick your class 6 32GB sd card .
More than likely there will be an app or tool to fix this in the short run. Never say never around XDA.

That would be my first guess.
I guess what is surprising me is for how long the phone has been in preview and in devs hands, why in the hell are so many features that are probably in the phone or are questioned to be in it, not being found already? God the first thing I do when I get a new gizmo is to search every nook and cranny of every option and setting. A good example is this and how NOBODY has tried it yet with a replaced microSD from an HD7, and how long it took for somebody to find a way to add your own ringtone. (Its right there in the Zune Hub!?! Who Knew!?!) lol
Seriously If I had a device at any point before/at the release, I could have easily found answers to a lot of questions that have been asked. Sadly with real life not landing me a job as a website tech reviewer or dev I get pushed to the back of the line. Not to toot my own horn but I really do feel like a fairly high quality QA person. I may not be able to write my own code, but I can poke and play with yours till I find all the bugs and all the features.
Anyone with a loner HD7 wanna throw it my way for test and analyzing purposes until I can get my hands on my own Sprint HTC 7 Pro? I can probably provide some really useful feedback and quality video that could easily rival a lot of these sites.

The reason is because it hasn't released to the USA yet. I have noticed that other areas lack the adventurous spirit.

Little bit off topic, but I consider my self to be a fiddler trying to find out every little option. I truely cannot find anything in zune on how to set ringtones?!
Where!? and How?!
In the tech video somewhere a day or 2 ago the guy said the option was within the zune hub. Of course no showing or saying how. Is there not a longpress on a song or the 3 dots option anywhere you can see?
Sitting stuck in the US really stinks. I wish Microsoft would give me a dang job lol. Need to get in touch with some more contacts.
That's because the setting doesn't exist. You can only use the ringtones that are on the phone right now.

Exactly. Geez, why are people refusing to believe this, it's a well known fact that at the moment you cannot set your own ringtones.
As for replacing the SD card in a HD7, been there done that. Works great, however HTC's WP7 hardware really sucks, so unless you're a diehard fan (or get them free) go with Samsung or LG. LG is actually the better choice in many aspects (just not, unfortunately, when it comes to hardware/feel).

Ok XP can only see one partition on a removable USB but if change the USB driver to a fixed disk driver then XP will see it as a hard drive then we can have lay down multiple partitions as we like. Now open regedit and goto HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USBSTOR
and double click on USBSTORE and you see a subkey below it, select the first subkey below USBSTORE and right click and select Copy Key Name
Here is mine, yours maybe different.
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USBSTOR\Disk&Ven_Generic&Prod_ USB_Flash_Disk&Rev_0.00
Now we need only need this part:
USBSTOR\Disk&Ven_Generic&Prod_USB_Flash_Disk&Rev_0.00
Copy and paste it temporarily into notepad.
You will now need this driver. http://www.xpefiles.com/viewtopic.php?t=92
Unpack it to a folder on your desktop. Inside the folder is the file cfadisk.inf. You need to open this file and scroll down to you see the line %Microdrive_devdesc% = cfadisk_install, specific data
Now you need to replace all lines %Microdrive_devdesc% = cfadisk_install, specific data with
the line you copied from your registry like so.
%Microdrive_devdesc% = cfadisk_install,USBSTOR\Disk&Ven_Generic&Prod_USB_Flash_Disk&Rev_0.00
There could be more lines so replace all and save the file.
Goto Device Manager and click on disk drives. You see your USB listed, dbl click on it and goto the driver tab and click update driver and install from a specific location and choose the driver to install and click on Have Disk and browse to the cfadisk.inf file your modified driver on your desktop and force that to replace your existing driver. It might ask you to reboot. You should now have your USB showing as Local Disk

I used this to make more partitions on a usb stick , maybe you can use this to make a local Disk of it and then make a new partition on it .
unfortunately I do not have XP anymore but diskpart under windows7 does not detect the media itself so it cant do a diskpart in the first case.
Its like the media does "not exist" anymore.
I really don't want to throw away my 16GB and my 32GB card and am still trying out solutions here.

The SD card cannot be reused to prevent piracy and information threft.
If you have business information on you SD card (say, emails, PPT/Word/XL documents), you don't want anyone to be able to just remove the SD card and use it in another phone. It's well known that WP7 uses a Raid-like setup for storage to show SD+Internal storage as one continuous unit.
Why people think you'd be able to just remove the SD card and view it in another computer/phone is beyond me... It's like common sense has gone AWOL these days...
Making the card unreadable improves security. Perhaps this isn't a big deal to many, but until you have a phone stolen/lost with confidential infromation on it, you don't know what it feels like to know that the informatin is safe and inaccessible to others.
Also, it's totally random which SD cards will work correctly in WP7 devices. The cards that do work are only shipped in bulk (to manufacturers, most likely), and aren't available for consumer purchase.
It's totally possible that a card may work right now, but as it ages it will start to fail and you will be forced to remove it.
Paying $200 for a 32GB Class 6 card right now isn't even worth the risk.
SD Card Size and Class has nothing to do with compatibility. It has more to do with random read/write speeds, which aren't the same as the card's throughput (i.e. Class).
That is probably why there aren't ay 32 GB WP7 devices available at the moment. If you want more storage you can either:
1. Buy a 16GB device and deal with it if it's enough for you.
2. Buy a 16GB device and wait for WP7 compatible SD Cards to become available.
3. Don't buy a phone and wait for 32GB phones are available (and maybe by the time the WP7-compatible SD cards are available and you can get up to 64GB storage).
4. Wait until a manufacturer releases a phone with 32GB+ NAND Flash Memory in it.
IMO, Microsoft should have dictated NAND Flash memory. SD cards do nothing but create support issues, and allow the manufacturers to skimp a lot (by using the lowest class cards available, among other things).

The more I read on the WP7 and its "expandable" storage the more I am convinced that MS has implemented RAID0 stripping to provide a higher bandwidth/speed increase in I/O and disregard data integrity error checking. This leads me to believe that WP7's performance on a slower media is horrendous (MicroSD cards), and without a doubt it is a cost saving for manufacturers because no one in their mind is going to pay a premium price for high capacity NAND storage.

Who needs a SD card again?

Why have the extra bulk of a flash drive when a 16 GB or so SD card could of just been slipped in behind the battery plate next to the camera?
Yeah I tend to agree that it's more about ease of use/portability than the size of the external storage.
My main concern for having an SD Card was having peace-of-mind that if by some act of God my phone died all of a sudden, I could still retrieve all of my pictures off the device by just pulling out the SD Card. Luckily there are plenty of apps out there that offer background synchronization to DropBox and other services, so not as big of a worry as before.
Would still prefer having an SD Card, tho...

Google's justification for the lack of the SD card was more about having a unified body of storage than anything else. Although the GNEX could have easily allowed for mounted storage without root.

If the card is seated securely and you are getting those errors sounds like a defective card.
Have you tried a low level format?
Have you tried other phones, devices?
If so do you get errors on those also?
Have you run any test on the card itself. Are you sure you are not mistaking issues with the new SD card permissions (or lack there of) for errors?
Those are some of the steps I suggest to figure out if the card is bad right out of the box, yes this happens a lot more than you think it does, or that card don't play nice with device this still happens even though it should not, or the card is on its way out. If nothing seems to be working try and get a replacement that should fix your issues and if it don't, don't buy that kind of card anymore

I have never had a issue with SanDisk but is the luck or unlucky of the draw[emoji1]
Formatting many times is no good for SD cards should really only format when you HAVE TO. There is really no need to format reformat... Usually after some time of using the card you can get back some lost performance by performing a low level format. But again really should only do that when you NEED to.
I have the Pro version (the Grey and more expensive one) Samsung card you have listed, I love it as far as performance and what not but I use it quite often for various devices not only in the N4, but for many people an expensive high capacity high performance card will be pretty much a waste (at least until root comes our way). Many people can survive on the devices memory alone, if I had to I totalaly could without any issues. Most things are streamed/synced/cloud and whatnot so there is no need to have a large amount of things stored on a SD specially when you take into consideration the new android sdcard permissions. Only system apps can even write to the card, no normal apps can.
This may change down the road hopefully, Google will be persuaded into changing that policy, or at least once we have root we can make our own rules.
Unfortunately Android has the stigma of being the "Least Secure Mobile OS" and I think Google is going to move in the direction trying to rectify this. That is going to be unfortunate for us I believe, because technically the statement that Android is the least secure of the mobile os's at this time is true. If the user knows nothing about computers, software, Linux and whatnot then yes this is true. But for many of the same reasons Android is considered vulnerable are the reasons the advanced user loves Android. Unfortunately I think many of these things are going to change and the advanced users will be stuck with solutions to problems we never had in the first place because the vast majority of people need there hand held in everything they do. LOL sorry about the rant but above that is my 2 cents of your card question.

I had the same problem with my Note4. I suspect this to be the cause of my recent problems with IndexService.
The last days I noticed an extreme batterydrainage. (50% in 4 hrs only cheching mail and reeding some ebook and newspaper) 44% usage by IndexService and 17% by screen.
At first i thought it was my Next UI . Deleted it . No changes.
Then I found out about similar issues on S5 and note 3 to be caused by corrupt pdf files. I deleted all documents, pictures, ... everything! Nothing changed.
i took out the SDcard. The same or even worse. Keeps the phone checking for SDcard when none installed?
So I reconnected the SDcard and formatted it again. STILL NO CHANGES.
Suggestions anyone?

I have the Pro version (the Grey and more expensive one) Samsung card you have listed, I love it as far as performance and what not but I use it quite often for various devices not only in the N4, but for many people an expensive high capacity high performance card will be pretty much a waste (at least until root comes our way). Many people can survive on the devices memory alone, if I had to I totalaly could without any issues. Most things are streamed/synced/cloud and whatnot so there is no need to have a large amount of things stored on a SD specially when you take into consideration the new android sdcard permissions. Only system apps can even write to the card, no normal apps can.
This may change down the road hopefully, Google will be persuaded into changing that policy, or at least once we have root we can make our own rules.
Unfortunately Android has the stigma of being the "Least Secure Mobile OS" and I think Google is going to move in the direction trying to rectify this. That is going to be unfortunate for us I believe, because technically the statement that Android is the least secure of the mobile os's at this time is true. If the user knows nothing about computers, software, Linux and whatnot then yes this is true. But for many of the same reasons Android is considered vulnerable are the reasons the advanced user loves Android. Unfortunately I think many of these things are going to change and the advanced users will be stuck with solutions to problems we never had in the first place because the vast majority of people need there hand held in everything they do. LOL sorry about the rant but above that is my 2 cents of your card question.

no and i agree with you regarding your rant.. it's just sad there is no recognition for the hardcore base user group.
So i think i'm gonna bite the bullet and buy the pro... I've done some more research and it seems that specifically the Ultra 64gb sandisk card manufactured a year or later ago has a technical 'fault' according to sandisk. i don't care for another sandisk so i'm gonna just buy the pro...
although i feel exhaustd with sandisk.. there is a 64gb extreme sandisk microsd ...
how is the quality of the extreme cards compared to the samsung pro?

I had issues with my 64g SanDisk ultra when I got my note 4. Worked fine in my note 2 until I moved it to my note 4. Then I started to get the SD card unexpectedly removed, constantly remounting. Formatted it in the phone in the computer nothing worked. Couldn't even copy back the stuff that was on it. Purchased a PNY 4k compatible micro sd and it works great. I will never get another SanDisk.
