Ok, I have this frustrating problem that whenever I tried to transfer files from my PC to the SD card in G1 through USB or download huge file (50mb+) from the net to the SD card, it will cause the G1 to lag terribly and freeze up.
The only way I can get it back up running fine is to remove the battery and boot it up again and have been doing it for quite some time recently since I need to transfer/dl files. I'm afraid if I keep doing that will cause my G1 to become a paper weight sooner or later.
However, there is no problem with putting files through SD card reader. I wondering is there a incompatibility issue with my current SD card and G1 since I did a search and only see a few having this issue with no viable solution to it. My last resort is to post here and gather opinions about this issue.
My SD card is 8GB class 4, if I'm not wrong, from PenDrive (some company I've never heard before) which I bought from my telco.
Should I change to a reputable manufacturer (Kingston or something) class 6 SD?
P.S - I'm using JF 1.5.1 adp firmware
My HD2 worked fine for the first few months I had it, but then one day my SD card unexpectedly crashed... completely... no reformatting, no salvaging, it wasn't recognized by the phone or my computer or any other device I tried it in.
No big deal, I thought, it happens.
I got a new SD card. Used the opportunity to try a new ROM (dZenkins 1.80.0515).
Started reinstalling stuff and after about 2 days, the new SD card started losing data, in less than a half a day it died too. Same thing, completely fried.
So I got another one. This one, in less than 6 hours, has started showing the same symptoms. I'm expecting it to die any minute.
All 3 cards were 8 GB, Micro SD. Seem legit (even if they're not 100% genuine cards, its unlikely all 3 would experience the same failure).
Also, it happened on my original ROM and now on the new ROM, so I think it's unlikely to be software related...?
With this last (3rd) card, I was very careful to always plug it in to the computer as a "hard drive" and to always eject it through Windows before taking the USB out.
So, I'm totally stumped. Any thoughts?
I did some research and it seems like from time-to-time HTC phones have had a problem with destroying their removable storage cards. Has anyone experienced this with the HD2?
Living in Kunming, China, its going to be tough to get an HTC repair on this thing...
Have you tried another MicroSD Brand?
Yep, tried different brands, still the exact same symptoms.
Same here. My card last only 2 days after purchased. Same problem, it just crashed, not even able to be reformatted or read by pc. It just "gone". Now I'm using 16G, and still working on the replacement. By the way, I'm in Jakarta.
same problem here
i use 16 gb micro sd
i started to have acces troubles to some of my folders
my firts card died 2 days ago
is not recogised anymore what so ever
Contacted HTC, they said try hard reset.
Of course I already did that, no change in the problem. I hard-reset after each failure, but the problem keeps recurring.
Other people who have experienced this problem: Did changing to a different size card help? Or changing how you synced your device?
Today I gave the HTC distributor a visit. They said that they HAD ALREADY WARN ALL THE SELLERS ABOUT SANDISK PROBLEM WITH HTC HD2!
Wow, that's quite a revelation!
So, maybe next time you better buy memorycard other than Sandisk.
I've had problems with the HD2 and microSDHCs. Decided to disable the storage card power saving features on a just in case basis and haven't had any problems since (touches his wood). Purely anecdotal but it worked for me.
Answer is here !!!
Hey Guys !!! I have HAd the same problem when i newly got my Leo ... three 8GB sandisk cards were ruined .. read only 30 MB ... i have changed to kingstone 8GB and now i have been working very good using my new card for more than two months !!
yep same thing happend to me last nite . i had a sandisk 8 gig card , and try to format it though my pc and still nowt .
i wont be buying a sandisk card again.
I'm using kingston 8Gb card since ever, no problem with it.
I been using a transcend sd card 8 gig and works fine, never though the cheap brand would be so good
Me too, Using free 8G scandisk .. 2 week gone, then change another 8G scandsk 1 mth gone, then downgrade to 4G scandisk .. 2mth usage gone, now change to 4G kinsgton, already 2mth old ...hope that fine ..
but my old Tytn II, from already 3 years old ..the 2gb kinsgton never let me down ...
Is it the phone structure cause the Sd card burn??? if I not wrong the HD2 processor is under the memory card ....
Reformatted card in my NIKON
Hi, I have had the same problem with my 16Gb SDHC card in HD2. Neither Windows or Linux could reformat/read/write the card correctly.
Tried my camera (nikon) which can reformat the card. Success!
Still the card failed when i copyed the old rescued /backup contents.
Then I removed the exchange sync to the card and moved the thousands of pictures and videos (Camera folder) (renamed folder).
And now the card seems to work again?!?
now I am able to take pictures and videos without getting a corrupted card...
hi,i'm from nanjing,china,maybe you got three 括容卡,i just buy two cards which were you described. Now i am using a real 8G kingston SDHC card and a 4G card
this problem also happen to me, twice ...sandisk and transcend 8G...now still looking the best SDHC for my HD2

If you were using WP7 then switched to Android than the WP7 is the problem. WP7 formats your SD card with a funky format, I forget what it is called. You see WP7 uses the SD card as the internal memory, WP7 native devices also do this to as they use SD cards for internal memory. Anyway the easiest way to fix this is to SD card in a adapter and put it in a digital camera and formatting it then format it on your computer with Fat 32. The digital cameras can remove that funky format and you will not have to get special software to do it.
Stupid WP7!!!!
I destroyed 2 SD cards so far within 1 day. It happened when I installed that new updateable YukiXbmod Windows phone 7.5 ROM. It just RUINED my Stock 2GB Sandisk and my 8GB Transcend!
I really hope that it isn't the phone f*****g those Sds up! Otherwise I don't know what to do!
---------- Post added at 10:22 PM ---------- Previous post was at 10:09 PM ----------
Pls if ANYONE else has issues related to this ROM or WP7 in general tell me if you have a solution!
EDIT: I feel stupid... My SD cards are both functioning and they are NOT ruined. They are only locked by that WP7 ROM. I find it embarrasing I missed out on the part with the 1:1 chance of locking your SD.
EDIT2: And it's quite easy to retrive the cards
I had 2 8Gb cards 'killed' by Xbmod Yuki Mango + Gingerbread Android off SD. One card lasted a week before just dying. Had it formatted in Nokia N95 phone, but even though the format went ahead, the message read that the card is locked and demanded password. I formatted again, after which it was no longer functioning at all - nothing could be done. So I got it swapped for the same, which lasted 2 weeks - the same story - it just died. When I came to the shop to see if they'll swap it again, they questioned the chances of 2 cards just failing within a short period of time like that. Now on a third card, different brand, but if it goes, I say it's the ROMs, not the cards.
I come from magldr 1.12 and I installed 1.13, after that I went straight to usb flasher and flashed a new rom but it keeps bootlooping, starting over and over again. anyone had this problem too? maybe some tips?
if it doesn't work after five more flashes, I'll put it back to stock first

hmm, I found the problem, I bought a new SD card today, this one is compactible, older SD cards aren't..
i would try a differnt sd card i havent had a single problem with wp7 since i flashed first time
Same here I have this problem with a Sandisk Class2 16GB restarting every 5 min or so tried everything formatted reformatted and nothing If I keep playing with the phone is no problem is look and unlock the screen normally but when is going in sleep mode by itself I can't start-it again everything is dead buttons lights don't came up, I give up and install a Sandisk class2 8GB no problems at all everything fine and no more restarting which led me to think not all the cards are good with WP7.

Your phone is the problem, It happened to mine and I went back to android, kept rebooting, then went back to 6.5 and it kept rebooting, turns out if it does that its a hardware problem and you have to RMA....

nothing todo with how old it is, its todo with random read/write speeds, for instance, most newer cards with high class values like 6 or 10 use some odd mechanics that increase sequential speeds but lower random speeds, that is the issue, if the card at any point isnt able to give the spec needed then it has issues, in some cases its only minor in others it wont even be detected.

evidently not, op stated the SD card was the issue and is now fixed when he replaced it.
interesting - I've now tried two WP7 ROMs on my UK HD2 - LEO70 and XBmod-WP7-V1.04b, with MAGLDR1.13 and 2.08.HSPL and 2.15.50.14 radio and got stuck in a boot loop with both.
The only thing that's fixed it was removing the SIM and both worked fine with any SD card I try. Doesn't make for a great phone though.....
Anyone got any thoughts?
EDIT - turns out it was my old T-Mobile SIM that was the problem. Have since tried two newer SIMs and both work fine with no bootloop!

lol whats with these bold statements?
how do you know its overheating? where did the overheating comment come from? the OP didnt say as anything to the sort
you cant assume that because you have had or have read about an issue with overheating which produces these symptoms that every time a phone does the reboot thing has the same issue
however lets take it out of context, yes if you have an overheating device for a along period of time then its not going to be good, but heavy usage of the device, heavy WIFI or HSDPA usage will all make the phone rather warm, charging the battery will make it warm, if your device gets too warm it may just crash, which happens in 6.5 as well.
Hmmmmmm ?
Can I just say that I think this forum is absolutely amazing... I managed to get my HD2 running windows phone 7 in only about an hour...
I too also have this issue, but at the moment I have taken the memory card out and just reading away here.... now am not a newbie when it comes to technology, just a newbie when it comes to this forum lol
Judging with what has been said the Memory Card used in the Windows Phone 7 needs to have fast enough random access memory in order for it to operate with the phone (As If it was Solid State Memory in the actual phone)
So... having read as well from georo - I give up and install a Sandisk class2 8GB no problems at all everything fine and no more restarting which led me to think not all the cards are good with WP7
So I am now going to take a wee journey out tonight to try and find a memory card similar to what georo has said... a Class2 8GB Sandisk...
If I too can get it working with this card then we could maybe begin a small list that works with WP7 on HD2

From my readings, it's NOT a matter of speed of the SD card. Although, a class 2 card is pretty slow...you should consider at least a class 4 or 6.
But, I digress, the issue with the rebooting has to do with the compatibility of the SD card and WP7. For some unknown reason, people have had to try a hit-or-miss approach to finding a SD card that works.
I have been fortunate that my 3C Pro 16GB Class 6 card worked right off the bat. And you might want to read up on the meanings and speeds of the various SD Class designation before spending money on a Class 2 card.

Ok thanks for the reply dude... as I have said I will need to get upto speed with this stuff... at the moment I have a standard SanDisk 2GB MicroSD... so suppose if I do go and buy a class 4-6 it will be money well spent anyway as I can always revert back to the old WM6.5 ... or just claim it didnt work and take it back...
Just on a wee note... I noticed that the HD7 which is pretty much the same phone runs on a Class 2 MicroSD (http://forum.xda-developers.com/showthread.php?t=883582)
Surely this should work?
also on this note... the card that comes out of a Stock 8Gb HD7 is a 8Gb Sandisk, Class 4...
please help why dose my phone keep restarting?
it seems to just have gotten even worse!
everythans up to date i just dont understand why it keeps restarting?
I think your Sdcard does not match to Wp7.
Change another sdcard and try again
I am using Sandisk 8m that for your reference.

I have 2 cards thay are both sandisc one is 16 gb the other is 4 gb i think thay are both class2 but am unsure thare is a logo that says c2 in the top right of the cards
however I dont think thats what the probulm is!
but am unsure.
I realy hope someone will help me figure this out.
Are you having this problem with BOTH SD cards, or just one?
The SD card, WP7, HD2 combination is very finicky. My Kingston 8GB c2 seemed to be functioning perfectly fine, with the exception of 6-7 hours battery life w/ little to no usage. I also noticed that it took a while for apps to install at the last step of a hard reset on 7720.
Thinking that Kingston was good, I upgraded to 16GB c4. The device wouldn't even boot past the splash screen after leaving magldr. So, I changed to a PNY 16gb c4 and got to see just how badly my 8GB had been performing. The apps that took a while to install at the last step of hard resetting Mango were installed in an instant. And my battery life tripled. I don't have to worry about my phone dying anymore.
So, it's very likely that your SD card can be causing the random reboots. Use dev_storagelock to unlock the card you currently have installed. Perform a hard reset. Stop the process when magldr starts and swap cards. Allow the new card to be integrated into WP7 and see if the reboot problem persists.

It's probably not the ROM and most likely the SD card. That's what WP7 does. It's super picky.

i did a haed reset and cleard all crc data the problum still ocurs
the only diffrence to both of the sd cards a i have is size
so unless i was to go buy a higher class im gessing buying another would be pointless
the weard thang is this didnt alwase happen
i used bttfv1 no problums
had bttfv2 then all sorts of problums started happening first time i flashed most of the updates with zune
then was forced to start from scrach agin after i messed up my registry with advanced config
second time i upgraded to bttfv2 i used the one shot method and im not exactly sure but i think thats when i started haveing the issue.
You allready know what's wrong, it's the SD cards you've been using. Keep trying with class 2\4\6 Sandisk cards.

what was that a sarcastic remark? & no i dont know whats wrong because as i stated before i didnt have this problum before my previous installation.
i am useing sandisk class2 16gb i am useing the card that came with the phone i realy dont understand why that would be the issue?
whats the best card to get then?
Your SD card would be the issue if the card or some sectors on the card lacks the required random read\access speed. This could very well create problems on one installation while working seemingly fine on another.
I've already said what cards I believe gives you the highest chance of working, you'll just have to keep trying with those. Theoretically you could also try reinstalling the whole thing and hope that no critical files ends up on the lower speed sectors of the card, but I don't know what chance that would have of working.
The only marketable difference between the cards may be size, but WP7 doesn't really care about that. When I we say that it's picky, we really mean it. You can have great success with one card, and then put another in of the same brand different class and WP7 will no longer boot. SD cards affect battery life and everything.
By an SD card from Fry's, if there's one around. They've got a 15 day return policy w/o restock fee. I only went through 2 cards finding the right one to upgrade to, but was prepared to go through their entire selection and the sales girl even told me to not feel bad about doing it.
Hi,
probably you must calibrate battery or yours SD card not works correctly...

I had the same issue bu not due to Sd card
I have a Kingston 16GB calss2 works perfect
The issue was that the original rom was American English
if i istall like it is everything works good and since i/m greek i can use also the buld in greek keypad with no problem
BUT when i change to my language the full functions of the phone , then it keeps
restarting byitself ....
For me no problem to work with the english menu at all , so i keep the device in english and works.
After my phone started looping, it was doing a full bootup to the homescreen then almost instantly freezing, I decided to update my WM7 to the new XBmod-Yuki updateable rom.
I did everything as it was said, install wm6.5, format card, etc. i even reinstalled everything hspl, radio, magldr 1.13 just to make sure everything was good to go.
NOW once i finally got it up, its freezing AGAIN at the home screen after it boots up......
I've been running WM7 for about a year (basically since it was available for the HD2). The whole time i've been using this same SD card, the 16gb sandisk HC card. (i'm assuming it's a class 2? (there's a 2 inside of a circle on the top right of the card, beside the word SanDisk)).
Has my SD card bit the dust? or what.... and if it has, does anyone know of a cheap card that 100% works? all i need is about 8gb.
Thanks,
Michael
ALSO i can remove the sd card and it'll run fine.. though i've got no contacts and all that stuff.

There isnt any 100% compatible cards that you can identify without trying it, although for a while i think AT&T were selling some in their stores in the states.
the problem is that an SD card may do 1 of several things, it "might" be 100% compatible, it might be mostly compatible or it might not work at all, the chances are most of us fall in to the latter two
Its only when you access portions of the card that will crash a mostly compatible card, for instance, i can copy music over portions of my card that fixes the reboots for me, but i might find that in another 3GBs time, i get more issue, so its like trial and error. Also because data isnt dumped on to the SD card sequentially problems can crop up any time so it might not be a new issue for you at all
I gave up on the Update-able ROM, I installed HD2O 1.26 LEO71_8107 ROM, and haven't had a lockup since, (it's only been about 12 hours though). I had the earlier version of HD2O's rom before i tried the update-able one from Yuki and XBmod. So IDK what's different between the update-able & the HD2O one. Possibly its the "sometimes work card" issue that you talked about.
