Database Users

Database of currupted sd cards.

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

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?

[Q] Omnia 7 - microSD card expansion

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.
@lvoky - Can you post pictures or describe what tools you need?

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.

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

[MOD] Moto G Working Removable Storage

Hey guys, so I know that there was a lot of false speculation about the possibility of altering the internal storage capacity of the G.
That was false, as the internal storage is actually an eMMC chip.
However, I bought a XT1032 model, with 16GB of internal storage, and, being a ruthlessly enthusiastic electronic engineer, I decided to take the matter of SD card support into my own hands.
I noticed, shortly after getting it, that my phone, being the single SIM variant, has an unused slot in the side, and, upon closer inspection, no important components around that area.
So it began; turning the unused SIM slot into a microSD slot.
I first went to PC World, and bought this tiny USB card reader:

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I then stripped away all of the plastic, and all of the metal USB connector. I was left with this:
I then took the microSD slot from an old phone:
The above image shows two contacts in the top right corner which are pressed closed only when the microSD is present.
This is crucial to the operation of this mod, because it enables me to distinguish whether the SD is present or not (more on this later).
I then glued the card holder to the reader circuit board:
I used pliers and a scalpel to remove the unused SIM holder, and scrape an indent in the phone's pcb, to give more space to the reader circuit:
Finally, I soldered (VERY carefully) the relevant connections to the inside of the phone's connector, used a scalpel to cut away any obstructive plastic, and cut a copper sheet to fit over the SoC, RAM, eMMC, etc.:
And then put it all back together. I powered the phone up, and used a charger and a 2GB microSD to test everything, and hey presto, IT WORKS!
This mod takes advantage of the USB OTG function of the Moto G. My modifications, while extensive, are essentially an "Internal, Switch-able, OTG microSD Card Reader".
This is where the card holder contacts I mentioned earlier become important. The phone uses pin 4 of the USB connector to detect what is connected. A certain value of resistance between pin 4 and GND tell the phone what a connected device is. For charging the phone, or connecting it to a computer, pin 4 needs to be dealt with by the computer or charger. We cannot interfere with pin 4 in these two situations.
If we kept pin 4 low, the phone would try to constantly power the SD card reader, and so would not accept a charge, and would soon run out of battery. The solution is to only enable OTG when the microSD is present. This means that for charging, I take the SD out, the switch on the connector opens, letting pin 4 be controlled by the charger/computer. The phone can charge up, and when it's finished, I put the SD card back in, and OTG takes over again.
Neat huh?
Many thanks, and I hope you enjoyed reading!

to charge the device we could use a very little switch that short pin 4 to 5 (but needs to remember to uninstall SD in software first)

and this is the reason why i love xda.

A quick question, does anyone know why USB OTG prevents deep sleep (More to the point, how I could disable this)?
It means that the battery usage when the screen is on is pretty much the same as usual, but when the screen is off, the battery usage is massive, as deep sleep isn't occurring.

Probably this is related to supplying power by phone to otg device. It would be really good improvement in next kernels to stop giving power to otg device when it is idle.
Currently, when u r copying some files, playing music from e.g. otg drive, when phone would go into deep sleep, transfer would be stopped because phone goes into deep sleep, so this also wouldn't be good approach...

Unfortunately, at the moment, a kernel module called 'msm_otg' is stopping the device from sleeping while the SD is inserted.
This means that I have to take the SD out when I'm not using the phone.
To solve this, I need to modify the kernel to allow deep sleep to occur. I'll post an update when I've solved this problem.
P.S; My username is actually Latin. It means: "The cunning of that which is hidden". It's about people's use of technology that they don't understand.

I'm wondering, if i use a ROM that has a Wakelock Blocker, like PAC-MAN, and use that feature to stop that OTG wakelock, will the OTG still work or not?
Sent from me using my tablet using an app.

The problem is that otg is not recognised as a system app or process, as it's controlled by the kernel, which is firmware.

[Solution?] Two sim + sd card.

Everything explained in this thread
You have to remove the chip from your sim card and place it on your SD Card

Has anybody ever tried this method? As I think doing this could possibly damage your SIM card.

i tried to create this "sandwich" too, but if i had compared my first product with the very tiny slot, i have stopped development until now. A sandwich like this isn’t so necessary for me.
This is not my post, but you can see there some pics about the way you have to go then:

I suppose anything not strong enough will avoid the correct contact from the card reader. From my small experience (only made it twice) the SIM position is crucial and a slight misalignment is enough for malfunction.
So:
1 - You have to make the SIM really thin to fit the SIM tray with the microSD, thus "destroying" it for future reapplications.
2 - The microSD is easily reused, just by gently and patiently removing the SIM and glue remains. Also, no metal part from the microSD is harmed.
You can always ask for a SIM replacement or a twin card. I have 2 with the same number and I can do all there is to do with either one.

I don't care about destryoing my sim card it can be easly replaced, worry about microsdcard if I glue a sim card to it how can I remove it in future ? Supeglue is kinda strong

Has anyone had an real success with this? I've separated the SIM contact from the plastic backing and removed any excess. I've trimmed all excess from the SIM contact (so no overlap with the tray) and have temporally stuck the SIM contact to MicroSD card with double-sided stick tape but no matter what I do I cannot get the SIM tray to slide back into the phone because the combo of the MicoSD + SIM contact is too thick. I even tried it without double side tape to see if if would go in but still no joy. Anyone got any ideas because there's seemingly nothing left to remove from the SIM contact or MicorSD. BTW, I'm using Vodafone UK SIM and 64GB Samsung MicroSD.

yes it's working for 5 month now. it's really Hard to get the sandwich into the Phone but it works and can be removed. if anything except the sim chip is removed You have to glue it on the sd. all other isn't strong enough and is too fat. Small drop off glue is enough and the sim can be removed from sd with cutter knife. tested it and sim and sd still working fine... Bend the edges from the sim a little down before gluing it so they don't jam up in the Phone

OK, now I have a big problem. I glued the SIM to the MicroSD using a tiny bit of thinly spread glue and the SIM stuck fine. I then tried to install the MicroSD/SIM hybrid into the phone and it was very tight. I g and jiggled and it JUST went it in with a firm press. The phone recognises the SIM but can't see the MicroSD so I've come take it out and try again but the SIM tray is stuck inside the phone and will not come out. I thought about removing the rear casing to help with this but the screw holding the case is behind the lip of the SIM tray. I have no idea what to do next!!
Would really appreciate some help on this.

I actually managed to release the tray with pliers and a strong thin nail pushed very hard into the release hole. It came free by a fraction of a mm, just enough to get a modelling knife edge into it to prise it open.
I've measured a few other MicroSD's and there are differences in thickness by +/- 0.1mm, which may well be enough to stop the hybrid card going in altogether. My Vodafone UK SIM was also very very slightly domed, not absolutely 100% flat.
The upshot of this is that it's imperative to check that the combined thickness of your SIM plate and MicroSD card will go in happily. I actually tried them together into the tray without any adhesive whatsoever and even this felt a very tight fit. I figured I'd stick them together and see if I could waggle them in - no I couldn't, of course it was even tighter.
This is a precautionary heads-up for anyone who thinks this is a simple and easy solution. In principle it is, in reality it can be a huge pain in the ass. Lesson learned.

Use #### dual sim + micro sd #### at the same time (with glue)!

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?

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.
