After couple of months trying to make WP7 to work on my HD2 EU, i finally made it, had all kind of troubles with different cards.

1. SanDisk 2GB Class2 (Bundled with EU HD2) - could install WP7, card was recognized, after one day of using and installing several apps the system starts to crash, random reboots each 20 minutes or so.

2. Kingston 8GB Class4 (Bought 1 month ago) - WP7 installs but can't get over startup configuration, it stucks, rebootings and Hard Resets won't help (tried a bunch of different ROMs, nothing helps)

3. SanDisk 8GB Class4 (Bought 2 weeks ago) - WP7 installed perfectly, no rebootings and everything works without any problems till now..

Thanks for the useful thread.

I just switched from Android to WP7, using a standard SanDisk 2GB. IT seems rock solid in terms of stability and speed.

The issue is it only shows 35MB total memory, and 0MB left!

Is it that the OS takes up almost the whole 2GB or is there something wrong?

Thanks.

Any statistics/update about compatible cards? I have the original SanDisk 2GB, on which the system crashes often, and a Kingston 8GB class4, mango works well, but very laggy on screen change sometimes (when swapping?).

I may buy a new card to get the best of WP7, but I am wondering which one.

Solution for Micro SD with WP7

After installing WP7 on my HD2 phone reboot every 5 mins and i've this message: error SD card

Everywhere it says that standard SanDisk 2.0 GB work, but it's not the case with mine. It's simply not found by the OS.

I'll give a try to your method and will report.

EDIT: well, Easus dos not even find the microSD on my laptop. It only detects the laptop's HDD... I wonder how you managed to make it work for you(?)
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] dazza9075:
'everywhere' is wrong, as stated more times than i would like to remember, there is no compatible list, it either works or it doesnt, class 2 or 4 seems to have more luck but beyond that theres nothing too suggest sandisk is any better than a ebay brand.

as for formatting it, i think thats hugely reliant on the issue with the card in the first place, im not going to pretend i know why this is the case but i think there are several levels of "not working" cards, the less serious seem to be fixible by formatting it, some are patched up by dumping more music on the card to fill it up past the bad bits others are detected but contine to have issues and others just wont be detected at all

from my experience you will get a much faster more stable card where you dont need to fart around with the card to get it working, but perhaps thats just me!
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Prerna:
Thanks, I indeed read that eventually no assurance can be given. It's quite a pain as we got to keep buying cards until we find the right one. I ordered myself a standard 8gb SanDisk with the hope it solves my problems. Let's see...

Patching or formatting a faulty one seems indeed a little depserate. Still I would have loved to try this one. But this Easus simply don't detect any card inserted in the card reader of my laptop; got to wait for the new card...
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] dazza9075:
it may have formated the card and thats why that program hasnt been able to see it, if you rigt click on "my computer" and go to "manage" you will see a disk management option, go to that and even if the card isnt working properly it should list it there so long as its even there. if that makes sense? anyhow, right click an format it within disk managment, then try your formatting program.

there are WP7 compatible cards but they are apparently sold in the states from AT&T, i dont know if you can get them but i do know they cost quite a bit more.

I bought a 16GB microSD card from amazon (Sandisk class 2)

However, it doesnt seem to be very stable, every now and then i get a lockup, and sometimes cant load apps!

So.. What memory card do you think i will have the best chances with!? Feed up with my phone being so erratic, i just want a nice stable phone!

[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] dazza9075:
you could try dumping some music on it, that works for one of my older cards, couple of hundred meg usually does it.

In short there isnt any easy way of knowing if a card will work

although in saying that there is some intresting reading on this thread

http://xdaforums.com/showthread.php?t=1150369

what you are looking for is a card with very high RANDOM access speeds, the problem is that the class system measures sequential speeds and no one really knows what the deal is.

Looking at the results on that page you can see some intresting reading, your Sandisk 16GB is listed twice, with very different results, that suggests more than one BIN part for that card (SKU), and this is where we have a problem and why some people can get a card working and others cant!

so even with that knowledge its still a large amount of luck if you can get a fully working card or not.

Seems like its not just write speeds as previously thought,

Random Read 4KB (QD=1) : 2.510 MB/s [ 612.8 IOPS]

Random Write 4KB (QD=1) : 0.041 MB/s [ 10.1 IOPS]

Random Read 4KB (QD=32) : 2.505 MB/s [ 611.6 IOPS]

Random Write 4KB (QD=32) : 0.052 MB/s [ 12.7 IOPS]

if you keep the write speeds the same and drop the read to around 500 IOPS it wont boot, like wise if the read speed stays the same an the write speed drops to 5 IOPS it wont boot.

Hi everyone I'm new here in the forum, samsung 16gb class 2 works perfectly on my hd2

Sorry for my bad English
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Prerna:
Well, instead of following your advice, I was able to re-format the card using Acronis on my PC which could recognize it. I tested with two cards: one 2GB SanDisk which was never recognized by the WP7 OS in my HD2, and another 2GB unbranded card that was recognized but totally unstable. I reformatted both using the method described a few posts ago by gsmspace (File sys: Fat32 systeme

Cluster size: 4KB &nbsp. Here are the "sad" results:

-SanDisk that never worked before: no improvement after the reformatting.

-Unbranded that used to partly work: not anymore recognized by my HD2!

It's surely adding even more confusion to the whole deal! I guess MS is well aware of this issue; so let's hope they find a solid solution soon. Until then we got to play dice until we come across a good card.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] dazza9075:
i doubt it, MSs guidelines were to have internal storage only, meaning cherry picked cards from correct batches, retail cards could be made anywhere with all sorts of differences, hense the difficulty in identifying working cards.

intrestingly i found that formatting the card with 4K sized prior to WP actually slowed the card down a bit, changing to 64k clusters improved read speeds but made no difference to write

I agree with the above since I also tried the Sandisk and Kingston. However, these are the results of what I experimented along with the two brands I mentioned above;

1) 8GB Kingston Class4 - Runs WP7.5 flawlessly so far. Been around 2 days since I installed and did dual booting with a SD GingerBread Custom Rom

2) 4GB Kingston Class 2 - Works good, is slow, so it's not everyone's cup of tea.. (Also just shows 75mb free after mango install).

3) 4GB Kingston Class 6 - Works Great!.

Righty, as daft as this thread is, there may be a good use for it

A few folk have been wondering about battery life, and how much its effected by the SD card. It kind of makes sence, our devices and software are all essentially the same, but we all have different SD cards, whcih may explain why some folk only get a few hours, and some a couple of days...

Anyhow, if you get the chance, dropping a couple of lines on battery performance might be big help

Sandisk 8GB class 4, has a few restart issues at various percentages of being full. Super quick and zero lag, Battery life with Wifi /BT off, data on, syncing every 15 min and used 2/3 hours of calls a day, lasts for about 12 hours, a charge, restart then view battery saver stats reports 1 day usage left.

Ive got a bunch of other cards thats dont work at all but ive given up trying to tell the world that every cards different, but needless to say a few of them are listed here as working, well their not, at least not "all" of them :)

Sandisk 32gb class4 battery consumption

I just bought a 32gb sandisk class 4 card.

Because I wanted to try a fully unlocked rom I went from the xbmod-yuki v2 rom (with radio 2.12.50.02) to the H2O v2.00b rom.

After installing however I noticed that my battery consumption went through the roof. With the xbmod-yuki v2 rom my battery lasted more than a day (with reguler usage of data, bluetooth, gps,...). Now it lasts only a few hours without doing anything.

With batterytool I can see the consumption at a level of -3800mV in idle mode.

What did I try already:

- I tried radio's 2.15.50.14 and 2.12.50.02

- I always did the camera-trick (put camera in video mode and let it focus)

- I also tried with the pdaimatejam-rom v7.5 but still high consumption

Could it really be that my new sd card causes this consumption?

Does someone have an idea if I can try anything else?

Thnx in advance for your help!

[General Questions and Answers] pppZero:
I'm working on a project for work, one of the stipulations is being able to lock a single SIM card to a device - ie; if the phone is started up without the SIM it was provided with, it will refuse to start up unless the correct security (not SIM) code is entered, or the correct sim is put back in the phone.

We are currently doing this with nokia handsets with great success, but we're also looking for more customisable phones.

Soooo.... Is this possible with android? All i've found on my handset is weather or not my phone prompts me for the SIM PIN.

The reason for this is a large number of handsets we're being "lost" and we were a little suspect of how often some employees were "losing" their phones. After we started locking phones to SIMs, far (far far far) less devices were being lost...

If anyone could point me in the right direction, I'll gladly give you an internet high-five! :)
