When I do a data transfer between my Mac and my G1 running Cyanogen, the SD Card immediately comes back as corrupted. I am unmounting properly.
When I have the stock Donut on the G1 it works fine, no corruption.
Any ideas?
This used to happen to me all the time. I guess the card wasn't compatible with the phone. I was using fat32+ext2, fat32+ext3 or even fat32 on it's own and I was always having problems.
If it doesn't happen on stock donut I assume it's an issue with our ext partition (if you have one).
I would agree with you except I am able to 100% reproduce it on the 3 SD Cards I have. I am using this method to partition my SD Card through the console of the Cyanogen bootloader: http://androidandme.com/2009/08/news/how-to-manually-partition-your-sd-card-for-android-apps2sd/ I have rooted and unrooted my phone a few times trying to troubleshoot this and it happens every single time.
What happens if you only use fat32?
I've had issues w/ two cards, including the one that came with the phone. If you can, try a Transcend card.
I have not tried just one partition of FAT32 under Cyanogen. I am going to try moving a file via USB with Cyanogen 4.2.4 in a moment. If that corrupts the card I will try just a single FAT32 partition.
I have used the SD Card that came with the phone, an 8GB Class 6 Transcend, an 8 GB Class 4 Patriot (which I know have issue with the Dream so I don't really count that) and a brand new 8GB Class 6 ADATA.
I really appreciate your help.
It appears that the latest CyanogenROM (4.2.4) has solved my issue!
I have done a bunch of 1GB+ file transfers via USB back and forth with my Mac, created directories, deleted files, etc and it's holding steady (just one random reboot but I can't say if it's related or not).
Hello, I'm not glad that i have to post this topic, but i think the whole story about "Waiting for SD card" problem will never end. I have 3 SD's at home, even one not works.
What i tried:
- i read a lot of topics about this problematics
- i tried to format my cards to fat32
- i tried clean cards
- i tried to format with special tools
- i tried customize startup.txt with msmsdcc_1bit msmsdcc_fmax=14000000 msmsdcc_nopwrsave etc.
- i tried 5 versions of android, even one not works...
I will be very glad if someone helps me or gives me an advice what should i try
Thanks a lot!
Is any one of the sd cards you tried a "class 2"? Seems that class 6 sd cards have this problem.

no need to try more versions on your current SD cards. Go to look for some very old one, better smaller then 2GB.
I got 5 in my home, 2 of them works. Both of them are 2GB, bought 3 yrs ago.
None of new one could be used.
i realised the old versions of sd card works but the newer ones dun.
U shuld change SD card~~
Pretty Disappointing... I'm stuck too. I'm suprised it hasn't been fixed yet can't be that hard compared to everything else they've acheived.
I hope everyone involved keeps up the hard work but it'd be great for someone to revisit this problem.
its a hardware problem of the sd card, not a software problem.
it will never be fixed (its not possible).
its not like an sd card is too expensive ^^ just get another one...
have a look at this thread

I tend to disagree. SD is a well known standard on the market.
The card that I have works fine for more than a year in Windows Mobile with Touch HD card reader. Without a single problem during that time. So everything: operating system, SD card and HTC HD card reader are fine.
It doesn't work with Android, so there is something wrong. Either with SD card initialization procedure, drivers or operating system (Android).
Unfortunately, I can't effort using 2GB card. I'm using my phone e.g. for books reading, music, photos, games etc. It's not only a phone I hope that all these hard working Android guys can fix this issue.

we are not looking at the sd card when its detected by the operating system but by the device itself.
the problem might be that the device is simply not capable to use some sdcards without the proper drivers (which the os then provides). what im saying is: before you enter the os the device might not detect some particular sd cards, but once the os is booted, it does.
the issue here is simple: if the device doesnt support the sd card, the os wont boot, this has nothing to do with the os.
if you dont believe me:
try flashing a WM rom from the "problem sd card". u will see: it wont work.
now try booting android from the same sd card. u will see: it wont work.
now get another card u can boot android with.
now try flashing a WM rom from this sd card. u will see: it will work.
conclusion: its a hardware problem.
i must say im not an expert but im not stupid either. i tried what i explained myself and thats just how it is...
if someone has a better explanation please correct me

What you're saying may be right. I'm not an expert either, so these are only my conclusions.
I think that what may be failing is the HSPL (Bios) that most people here loaded. I'm pretty sure that I was able to flash from SD card on my stock ROM. At some point it stopped working. I'll try to rollback to stock SPL (I'm not sure how to do it, yet) and confirm. So changed HSPL may be the issue.
Another question is, why SD drivers in either case are not loaded with the boot image. I don't know Android internals, so I can't tell if this is possible. But it would help in this case.
In both cases I don't think this is hardware issue that can't be resolved.

Sorry. You are wrong. I am frequently flash my phone using SD card with HSPL. But the card also face problem with Android. So definitely not the hardware problem.
Hello
I have 2 card's, one 8GB from Transcend and one 4GB from Kingston, and the kingston only works with android!
UPDATE: Transcend Class 6, Kingston Class 4

lucky guy
From my personal experience on my Kaiser I can confirm that newer SD cards do indeed seem to cause problems in Android, especially with installing or running from SD.
I have 3 SD cards I normally use for my phones, the newest a 4Gb class 6, which I have never been able to use for Android on Kaiser or Blackstone, I can't even flash with it, it just never works, using it for data storage works fine, just can't run Android from SD or Flash with it, the other 2 are 2Gb class 2's, both work just fine for flashing, and work great when using them for running Android builds from SD on Kais and Blac hardware.
My conclusions? Well I fall into the 'hardware problem' camp, mostly, since I can't flash either Winmo or Android with the class 6, it may be the card, but I wonder sometimes if it's the capacity, since both the class 2's are almost the same age as the class 6, all are sdhc, all 3 are from the same manufacturer , (SanDisk), in fact the only real difference is the capacity.
Waiting for SD Card
I have also tried a Transcend 8 GB SD Card and it doesn't work.
The same files on a Tanscend 1GB SD Card work just fine, so it's definitely a hardware problem caused by the card.
I've tried everything - formatting the card with different tools and different cluster sizes, partitioning the card below 4GB - all without success.
For all you guys out there with the "waiting for SD card" problem: Get a different (small) card !! - It's worth it !
what about this - copy files in the package into device internal memory and boot from there(i don´t know where to change booting directory in cfg...). if it created data.img on the sdcard, it would be fine solution...

Not sure it's that simple... once winmo is killed, the internal memory would have to be accessed natively by Android. It could be different for every device (where as SD is a standard, device agnostic format, internal memory isn't)
Whilst most HTC devices will work in an almost identical manner, there is no guarantee of what the internal memory is (it could actually be a HDD in theory).
I had this problem with my Transcend 8GB SD card, nothing solved it so I traded it for a Sandisk 8GB SD card with a colleague.
Works fine now. ^^

I'm using a Transcend 8GB card...the one that came with my blackstone with no problems at all. Don't think I did anything special though, formatted to FAT32, installed android from a CAB (in this thread) loaded Android and then I copied my WinMo files back to the SD card as well.
One 2GB sandisk card I had though didn't work at all until I formatted it to FAT32 under linux, then it worked fine in WinMo and Android.
A friend also suggested to me trying to reduce the 'allocation unit size' when formatting the card but I've not tried that approach.
maybe u can try format SD Card to FAT (not FAT32 formatted i think.. maybe it FAT16)! i have 8gb and 2gb SD Cards.. and that all cards not work untill i formatted my 2gb SD Card to FAT!
CMIIW..
Other people have probably already discovered this but I thought I would share this information.
I was using an SD build of Android on my HD2 and had problems with it losing files during USB connection. I switched to a NAND build with data on SD card.
The corruptions on my SD card caused system errors, force closes and mismatching system UI numbers.
This got sooooo bad that I had resigned myself to buying a new (and bigger) SD card.
However, whilst browsing the ext4 partition threads I read about the Panasonic SD Formatter V2.0
Apparently formatting an SD card using windows isn't good enough for SD card standards. The Panasonic app sorts that.
So I copied all my files off, formatted the SD card (takes about 10 mins) with complete erase on the Panasonic app, copied them back and re-flashed my Android build.
I have now been using the card without error for over a week and am blissfully happy with Android on NAND.
Damn, I love this forum!
(Might still buy the bigger card though! )
Cheers,
GG

I had exactly the same problem, it began with corrupted files, constant errors, FC and restarts. At the end it was so bad that neither device nor PC could not read the card. Panasonic SD formater the only thing helped. However from the 2nd attempt, quick format didn't work long I.e. problems came back in few days. After full format everything seems to work OK. It's been OK for 2 weeks now
BTW card is Sandisk 8gb class 2
Sent from my HTC HD2 using XDA App
excuse my ignorance
but...how exactly do you use the panasonic reformatter? I downloaded it to my computer but after that i am lost. I tried to reformat sd card through usb connection but does not work i am at a lost now. Again please excuse my ignorance and be kind.
Put the sd card in a larger adapter card and put it in a laptop or external cardreader

Ive been able to put my sd card into a camera and format when I have had trouble like that and it worked.
hi,its my 2nd day having a hd2.
I think my card isnt comaptible to wp7
its a Rdata class 6 16gb card.
I bought a used t-mobile hd2 running on stock wm6.5
and decided to dual boot on wp7 and android
the thing is when I installed LEO70 ROM everything went well.
no reboots or anything like that showing incopability of the sd card.
BUT, apparently when I was going to prepare the sd card for partitioning as I read on guide I followed.
my card reader wont pick up my 16gb rdata class 6 card. OUCH!
even my old nokia phone rejects it and says its unformatted blah blah blah.
plugged it in again on the hd2 then went to zune and zune says 0 free space.
plugged the sd card again on a card reader and still no go.
tried another card reader and still it wont pick it up.
then tried another card reader.
this time it reads but for minutes and minutes for scanning.
no drive letter.nothing.
tried a 8gb card and ALL the reader picks up.
opened sdcard formatter and it wont pick up my sd card.
MAGDLR 1.13 wont recognize it too. all I head is the sound of a hardware being connected to the pc and that's it
please someone help me here.
I will be so glad if you could help me with this problem
I wont go back to wp7 again after I resolve this.the sd was working
how DO I revive the sd card for other use?if I canr use it for wp7
I dont wanna waste another card trying though.
note: Im currently downloading a stock t-mobile MR 3.14.531.1.exe
is this safe?and if I successfully install this will winmo 6.5 be able to format my sd? please I dont have extra money to buy another card cause all of my sd cards are being used by other phone.
thanks in advance
Get yourself a copy of SDFormatter. Put the card into your PC and run this free utility. You should then be able to do a complete format through Windows.
Your sd card is not compatiable. There are many threads in xda about this and how to format, copy partitions etc. THis thread is also useful giving you links for partition/format utility http://www.techienote.com/tag/technology
Format your card and use it for something else. Have a read of the threads in the wp7 hd2 forums, there are a few threads about which cards reported that work, I use a transcend 8gb class 6, works well.
ok thanks will try reading more
and by the way I have sd formatter but it really wont pick up my sd haha
ok thanks will try reading more
and by the way I have sd formatter and easeus but it really wont pick up my sd haha
what a shame.
another wasted money
Was reading earlier somewhere on here and they were talking about a low level formatter. Then format it using regular tools. What ever that is not sure but apparently it fixes some of these problems.

My HTC HD2 works with my Transcend 4 GB microSD card, but it won't android won't boot up with my 8 GB Verbatim microSD card. Do I need to format it or something? Thanks!
Are you sure you have the correct set up ? (Files are copied to their destinations)
Try to format it to FAT32, and try again.
I`have just formated it to FAT32 and still the same problem. What files are you talking about?
PS: Sorry to bother you with "stupid" questions, I am pretty noob in this
I have read that Verbatim SDCards can cause problems in the build; booting or running, SanDisk is your best bet, but you may still be able to get it running,
Im not a dev; just brought SanDisk as a result of this,

It depends on many factors. Which Android Rom do you want flash, does this need Ext 3/4 Partition on the SD Card ? Do you have flashed the right partition size ? Read the installation instructions of Rom you wants to flash, there you mostly find all information.
Are you talking about NAND or SD? If NAND, make sure the ext partition is set up correctly, as this is where a lot of the apps are stored. If SD, then I would assume you know how to install an SD build so it could be a problem with the SD card being incompatible as alex.odell.2011 said.
I've had similar problems sometimes with my SD card; my HD2 wouldn't boot unless I took the card out then put it back in once it was booted. The only thing that I thought might cause it is something CWR related on the SD card, since I had used it in my Hero and Droid 1 as well to flash ROMs to them. It was a class 4 16 GB Sandisk, if that helps at all.
