Due to the amount of cards dieing. I want to start a database of dead cards to see if there are any patterns. I would like to have: Brand, Capacity, and where it was made. (if you can think of any other important info, I'll add that as well)
Just post the info and I will keep the original post up to date with a list of failed cards.

Huh? I've been using the same 8GB MicroSD card, SanDisk, for a few months now. Always works the way it should, and I've reformatted almost as many times as I have hard reset, which is a bunch.
If you read through the android thread, there are a bunch of people who have had cards quit working. I'm wanting to see if it's a problem with cheap cards or if it is something else. I'm willing to bet it's just cheap cards that do not perform write leveling.
Sandisk 4GB, speed rating 2.
Transcend 2GB
never failed yet .. still running happy, even with dzo's Android port
Transcend 4GB SDHC assembled in Taiwan.
2 months of normal use, and now corrupt. Returning for a different card

This thread is clearly for cards that DO NOT work. Who's to say your card fails 4 months from now.

I think its also important to know cards that are working as well.
Mine's probably not a SDHC, which maybe why it seems to work so far.
Ive been using Android for 3-4 months without issue on my SD card
cheap manufacturing
That's my conclusion well partly, I've been trough many sd cards and brands mine's and my friend's (they always come to me when something goes wrong)
after using many cards from the same manufacturer I had one or the other fail for no apparent reason,always make sure never to pull a card out while it's doing some operation, never write the card to full capacity either,there's nothing said on that , but just to be safe,still they keep failing. one thing I've notice is that this is happening more frequently lately more often specially on the vouge phone with wm6,and of course the bigger capacity cards.
I have to agree on the poor manufactoring. I have seen a huge increase in dead flash memory products recently. (3 or 4 friends with flash drives and one with an sd card)
I have noticed a difference in where they are made though. The Japanese cards seem to be of higher quality. That's one of the reason I wanted to keep up with where they are made. None of the flash drives i've seen dead have been made in japan.
The poor quality will eventually catch up with them.

I think you're 100% on the money. It's hard to reproduce card corruption as it seems very random as far as the damage done, and frequency.
Most PDA users (myself included) load up an SD card with 3rd party software as apposed to internal storage which is somewhat limited in size. This leaves plenty of room for Program Memory and less hangups.
It only makes sense that piling software on the SD card will cause an increase in simultaneous reading / writing over a period of time. Removing an SD card while the PDA is running / or even idling could easily cause a corrupted card, depending on whether a piece of software was randomly accessing data on that card at the moment of removal.
Now what can be done to eliminate this problem?
We need to develop a simple "switch" to isolate the SD slot from communication while removing or swapping a card. Microsoft realized this issue with SD cards and developed a "Safely Remove Hardware" wizard from your desktop PC. I've never had problems with SD cards / flash sticks once I religiously used this wizard to and from my PC.
Could someone development savvy write this code for PDA's, since Microsoft didn't feel the need to incorporate this functionality onto their Windows Mobile environments. I wouldn't know where to start lol.
Anyone agree?

whats going on? using t-mo 2.17 rom
Same here
Same here with 2.17 rom, no problem with older roms...
wtf, today at work my memory dissappered from the OS.
i just losted a bunch of data! wtf.
does the 21 rom do the same thing?
i don't know whats with my phone, but the memory card would just disconnect. like it won't read it anymore.
in the morning i see it. but by the afternoon, it's gone?
im using a 2gb stick on a 2.17 thanks.
pfffff... again, same here...
hmmmmm.... seems ur wizard catch the flu from mine :twisted: My 1 gig sandisk mini sd is vanishing few times a day also, even with 1.6.7.1 wwe qtek rom...
does anyone know how to fix the stupid problem!? its getting on my nerves!
I had exactly the same problem. Also, transfer speeds where very poor. In the end i ended up buy a new card which sorted. Turns out i just had a bad card off eBay.
I have had the problem of the memory card seemingly disappearing.
On checking closer, I noticed I had 'Storage Card' and 'Storage Card2'
Storage Card had one file on it and everything else was still on Storage Card2.
By deleting Storage Card abd soft reset, all was restored.
This has happened a couple of time.
If this happens to you, make sure you delete the right one.
mini SD
I've never unlocked the extended rom (Storage_card_2), so i have just Storage Card, a 1 Gig Sandisk mini SD. Still, it dissapears a couple of times a day, and i must soft reset my Wizard to appear again. Very, very frustrating
Missing data
Something similar has happened to mine as well....
I turned my PDA on and accessed the storage card just like I do on any other day, only to find that all of the files had disappeared!! Everything had gone - but when I went into the memory setting, where it tells you how much space is used on the card it is still showing up as being half full i.e. the data is still there but not showing up on explorer!!
What is this all about??!! It has never happened to me before!!
Just wish I could offer an explanation on how to fix this...
By the way I my rom is 2.21.4.1 - which is different to the ones posted above...
Ive had this problem 2-3 times before
to solve the data gone missing i just take out the mini sd and put it in again..
if that doesnt work...take mini sd out...soft reset...insert mini sd when the today screen shows
worked for me :idea:

nope that doesn't work, i'll be happy if it was as simple as that. what i would do is, plug the card in my laptop to read it, then safetly remove it.
then insert back into my phone, this is the only way for it to work for me.
Has anyone taken their Omnnia 7 apart yet to see if you can replace the microSD card with a higher capacity one?
It's been done on the HD7 so we need a brave volunteer to try the same on the Omnia.
This is really intriguing to me... if anyone does it please take lots of pics!
You're on the OMNIA 7 has a MicroSD slot?

No, not a normal slot.
In some mobile phones with windows 7, the MicroSD is hidden inside.
You cannot access without unscrewing, and it voids the warranty.
The phone must be taken apart into pieces to find the MicroSD, it is not one you just change for different music all the time!
We need a person to volunteer to take apart their phone!
Windows Phone uses a special high–performance SD card that works differently than SD cards in other devices.-Microsoft

exFAT disk format maybe?
I have an Omnia 7 testing device and I am willing to disassemble it. But I really don't know where to start with this. Seems that the phone can be disassembled only with special tools that I don't have...
Omnia must have a slot like the HD7?
Got this from a link (I am a new user: so can't post links yet: here's a goo.gl/Vi0e)
While the Omnia 7 has an microSD slot, it isn’t your run of the mill one. The microSD card that comes with the device is essentially locked to the device. If you remove the card, it will make the phone inoperable. I did read a tip that this may change later on, or if you swap cards and reformat then you have to suffer with losing your data, but that hasn’t been officially verified yet. Also someone will probably figure out a hack or way to copy the formatting scheme over to a new card to avoid losing your data, so don’t fret too much about this.
Just got delivery of Samsung Omnia 7.
I'm trying to open it up but I can only get access to 1 screw..the other ones are partially or fully obstructed!
@karthikraman - there is no card locking going on and upgrading memory is fully supported by MS. It just has its own special procedure and consequences. Too many tech writers have been reporting this as if it's some kind of hardware hack special to the HD7. Nonsense, as I said it's supported and designed to work that way.
Manufacturers have decided to hide the cards inside. Maybe they thought that was safer so that people didn’t swap in new cards and complain their phones had stopped working or, if they did the hard reset, that they had lost all their data.
Anyway, all we need to know is whether we can get to the SD card in the Omnia 7 or not. If we can the upgrade ought to work.

Well, I can post some pictures later, but generally, as hboos mentioned, the screwes under the battery cover are partially obstructed with the rest of the phones casing... Which means that before unscrewing these, the casing has to be somehow removed. There are no other screws on the phones body, so I guess the plastic top and bottom part of the phone has to be "unclicked" somehow. Or maybe we have to begin from the display, like with iPhone 3G for example...
OK, I have got it apart, but haven't found the SD card yet.
Where the slider is for the USB charger, use a small screwdriver & gently prise the plasic up (with the slider open), gently work your way around to get the complete cover off.
There you will find three screws, once these are rmoved the end will come off, after which you can slide the metal case off. You can then access all the screws.

take photos and videos if you can would love to get a 32gb card in my omnia
Thanks Vince!
Taking it apart just now!
Just for clarity...to take the first bit off, open the usb slider and put a screw driver in to take off the plastic from the END of the phone... then everything is easy from there.
is it possible for the microsd card to be underneath the sim card slot or inside the area with the antennae?
Update:
I've pretty much dismantled the whole thing...just need to get the screen off and I can't seem to locate teh sd card.....it might be underneath the samsung sticker?
I have two photos but don\t knoiw hwo to put them up...they are 1.5 mb in size
Right guys,
After faffing around with this...the microSD card must be located just beneath the screen..unfortunately, I am unable to check for sure because the board has connections glued on to the sides for the power, camera and volume buttons..
what a downer

HTC, and maybe Motorola, is known to use microSD card for internal storage in various phones. Samsung, on the other hand, doesn't do that normally. All the Galaxy S phones have flash chips mounted directly on the circuit board. Samsung makes those flash chips, so it makes no sense for Samsung to use someone else's microSD cards.
Nice try and thanks for giving it a go.
Here's more info on the official position from MS:
http://windowsphonesecrets.com/2010/10/29/microsoft-speaks-on-micro-sd-and-windows-phone-storage-expansion/
I said on an HD7 thread that I think they are just being really careful and making sure they minimise potential problems - they don't need the launch to collapse with any Apple-antenna type bad press.
I think I've decided to go for an HD7 and will probably upgrade the memory once I've used up the 16GB.
there is no card in omnia7

Well on the bright side at least we wont have the memory failures prominent in SD-cards Charlie Kindel spoke about.
Sooooooo, I replaced my internal sd card with a 4gb class 10. I used the "cut away the plastic" covering the card method because I was too lazy to take the phone apart. Now the phone will not turn on. Tried placing the original card back in......still nothing. Plug the phone in and I get a battery symbol with a yellow triangle and exclamation mark. Any thoughts?
I pried up the one edge of the piece of plastic that I removed which was close to the contact for the back cover, so maybe I messed up that contact and the phone thinks the cover is not on there? Was there not a fix for the Streak to eliminate the need for the back cover to be on for powering up?
Any help is sincerely appreciated since I now have no phone, which is clearly not going to be warrantied. Congratulations me
Don't know if this helps because it requires what you didn't want to do - take your Streak apart. But a quick look at that tutorial and it seems that the 'switch' for the back cover is not near the internal sd card, so perhaps your problem is something different?
Did you do a reset from the recovery? I believe that you need to di that to initialize the new sd card?
There are a few threads here and at MoDaCo dealing with the replacement of the internal sd card, more reading may be in order.

The innerSD is the black square in the top right corner, slightly to the top and right of the sd card picture (that is the outerSD slot)
The battery cover switch is near where the greenish square in the bottom left corner.
It's possible he might have damaged a trace that connects the switch, but it seems a bit unlikely for it to run exactly where cut and also happened to be the only trace damaged.
You could try installing streakdroid as it ignores the batt cover switch, assuming that's the only issue

The inner SD Card is just a 'normal' micro sd card, so yes if you remove it you can put it in a card reader.
Whether making sure that the inner card is working properly it will fix your problem is unknown.
If you have not taken your Streak apart I recommend cutting the area above the inner card to remove it. I have done this to two Streaks with no issues. YMMV.
Thank you marvin,
Ill try it tomorrow, hope it will fix the device.
Sent from my Dell Venue using XDA App
The innerSD is formatted in ext3, so you'd need to be able to read ext3 partitions if you wanted to examine it's contents
A few days ago I used TheManii's guide for flashing an image to the innerSD and it went off without a hitch, and solved a small error I was getting when booting into recovery. So if you want to eliminate a variable, I would highly recommend that so you know it has nothing to do with your problem
so just recently the HTC Universal got their phone up and running on CM7 by notime2d8
http://forum.xda-developers.com/showpost.php?p=19923156&postcount=416
As some of you might or might not know, our phones are quite similar.
the Developer that made the HTC Universal version will be making some test versions for us to run in our Athena phones
Anyone willing to help feel free to check it out
Wow....I guess i really have to do it now that there's a post.
I must say though, that i'm only adding echo31's and ftoz's work to my kernel so all credit should go to them.
I don't have a x7500 to work with, only a x7510 so it might take a little longer to get android working on this.
So... without futher adieu my first test kernel for the athena. Link
You will need all the files on the root of your harddrive. Launch haret and let me know what happens.
i too also have the X7510
the only difference between these models are the storage devices, one is a mechanical 8or16GB HDD vs a 16GB flash disk
downloading the files as i type this... will be back later with the results

If that’s the case then this won’t work for you. On the Linux side there’re big differences between the two. The main thing being that there is a working driver for the X7500’s hard drive and the x7510 uses a 16gb SSD which we're not even close to getting to work in Linux yet.
can we use the External SD card as the hard drive instead?
then we only need to maintain 1 build that works for both devices.
here's what i got when it tried to load, it went pretty far

forgot the keyboard at home, so i can't test much without it.
I can do some tests but I hope not having to wipe the AGB 3.0.0 on my x7501 though (still have it as haven't sold it), but I have never heard that it can boot from SD at all, so it still would be initializing from the internal PROM and then pass on the boot onto the external SD if required.
I agree that a fast SD can match the performance with the MicroDrive, but both are not connected to the memory the same way?
This is surely very interesting indeed.

Yeah if possible could you follow the link and download the files i posted above and report back. Nothing should be erased from your phone. There is no working driver for the athena memory card slot yet, only a driver for the x7500 micro-drive and not the ssd in the x7510. I just thought about it though we could probably boot from a jumpdrive as usb host is working.
i can easily test that as well, from a jumpdrive
i have my original extension for multiport USB+mouse+keyb and video out, that came with the HTC Athena

If we can pull this one it would be like reviving an old friend.
Thank you guys for all the effort!!

Here's what i got so far..
I have a 7501 and can report the same result as AllGamer at this point.
Currently seems to be hung at "db_open adb find '/system/bin/sh'"...
And after the long wait, end state seems to be the same as reported by AllGamer as well.
"adb_open"
godspeed
This is great! I have been hoping for this. I still use my 7501 everyday (even as a phone) with WM6 limping along. I bet there a lot of users, iin addition to programing geniuses, watching this thread. good luck!
Whaouh, it's alive ^^
My x7500 is asleep, but i'd really like to see Android waking it up ! (bad english ?! )
Animo, mucho ánimo, yo tambien tengo HTC X7500. Gracias.
Yup i finally did it!!!!!
I hope everybody knows what these pics mean...
Ignore my workspace/bed in the background. My battery died after this...will post more info later.
Update...
So for the update nothing really works. The kernel is 3.3-rc4; only video out, usb host, and the disply work. Running cm7.2 from my jumpdrive.
That's already something!!! we're patiently waiting!!
Take your time!!!
our hope is everlasting!!!

Hey Mi Lover and other engineers!
You must deal with this problem have
The solution is simple
Without using special equipment
Only the amount of glue!
You must do the following steps in order to get the correct result
1- Pull out the metal part of the SIM card with razor blade

2- Stick SIM card with amount of glue! (just a little!)
attention:
1- This work is very delicate so cut the around of sim card carefully with razor. (careful dont cut ur hand )
2- dont use amount of glue to stick sim card to sd card. (if u use a lot of glue the height of sd card will be increase and u cant placed sim's slot!
3- It's better use 3G sim card to do it (the IC's are smaller than 4G) if you use 4G press and smash edge of sim card to sleep on the sd card!
4- and last guidance is use 128gig smartphone it's difficult way if u are impatient!
Press "Thanks" if this article was useful
Thanks, tried with 4g sim and 64gb sandisk and works well. Used for 2 weeks now without any trouble.
Only the problem is I managed to put them in... it was hard to do so as it was thicker 4g sim. I used little force.
Now I worry how will I get them out (haven't tried yet)
Edit: After another week I tried to pull sim tray out and it came out ok.
Don't try this, I ruined my SD card as well as the SIM card. This works great, why take the risk?
http://www.ebay.com/itm/Nano-SIM-Ca...677615?hash=item4b0faf0d2f:g:WlwAAOSw5cNYgc~V
Well I have broken two sim cards when trying to install this way, all was in pretty good visual condition (not so ugly as above) and fits perfectly in the bed with sd card. Seems that sim card is very sensitive to any pressure when is "naked", but this extender is maybe some ugly solution.
The extender fits in my (flip cover) case without any problem and so the SIM card is very well hidden, you can't see or feel it. If you only use a silicon case you will slighty feel a little bump where the SIM card is attached.

I don't know, on my Mi Max I'm still on Android 7 (using GlobeROM). On my Samsung Note 7 however, I'm using a custom ROM on Android 8 in which this option of simultaneously using 2SIM & SD was made available again (I thought Samsung had blocked this option, but it seems Android 8 is doing that...). So, I guess developers might know how to bypass this.
