[Q] Repurposing a card reader with Android? - General Questions and Answers

I have one of the card readers provided by Square (at squareup.com)when you sign up for an account with them. I know there are other card readers out there, but, this seems to be the simplest; the insides are literally just a card reader, no security or anti-tampering for what I can tell. Would it be possible to take the card reader and make it to where you read/write on magnetic strips, and if it could be used for educational purposes?

Activesync how to load a huge file straight to MMC card

I have just bought a 512MB card & wish to transfer a 133mb film to it how do I send straight to the card using activesync
Thanks Graham
sd card reader is the only way i know of.
If you want to start transferring large files, you 'must' get a card reader. They're dirt cheap now and will transfer your files in a whiz. It will take what seems like a lifetime doing it through AS.
If you must se AS, right click on the green AS symbol in the systray and select explore, from there you can navigate to the memory card and just drag/dropv the file as always in windows.
Heed the previous warnings though, it will take a long time; a card reader is about £6 and will speed the transfer up by orders of multitude.
Also, if you are going to be transferring a lot of big files you could try my new software which is underdevelopment, it sunchronises any files on the PPC to the desktop including memory cards, and will very soon have the capability to do the sync over a card reader to the memory card.

Thanks all
Unsure if it is the done thing here but I'd like to thank all those who have helped - I used the Explore feature as I didn't have a card reader & you were spot on as it took ages.
The 1st time I tried it crashed half way through I then had to reinstall Activesync which then interfered with my cordless mouse so I had to reinstall that.
On the 3rd attempt I finally got it done so I shall be buying a £ 6 card reader ASAP as it took 2 hours to sort LOL..
cheers again Graham

Move Data between memory cards when travelling

I'm searching for a device that allows me to move files from one memory card to another while on travel without a computer (only with my HTC HD2).
So I could made backups from photos and other data.
It seems to be impossible to connect an external card reader or memory card to a pocket PC.
So this may be an interesting solution:

Are there any alternatives?

Can someone please explain the SD Card issue to me....

What exactly is the problem? Im thinking of getting the focus and I keep hearing these SD card issues but what "exactly" is the problem? I understand that once you put it in, your SD card is done, and that if you want to remove it you have to wipe everything, I understand all that, but what are the problems that arise? I have a 16gb micro sd that I have used on all my devices no problem, do files get corrupted or something? Does it just not read it?
There aren't any problems in that sense. The only real "problem" is that not all MicroSD cards work with WP7. In addition, hot-swapping isn't supported, because in effect, the MicroSD's memory is added to the internal memory, and the system then doesn't differentiate between storing on the sd card and that that's built into the phone, and thus stuff is spread all over all of them.
There aren't any "problems" as such that I know of though.
On an ending note - WP7 is awesome ^__^ Honestly the best user experience I've ever had with a phone (esp. having come from Android >.<) ^__^
loading a microSD card will turn it into a secure card. once this happens no other device will even read it (except a nokia n8) making it extremely difficult to format if it doesn't work nicely with windows phone 7. That is the main issue. rest already mentioned.
GenkaiMade gave his version which is correct but I thought I would explain it my way.
Take your average memory card and device. What are some of the default expectations you have when using one?
1) You should be able to get any MicroSD card on the market and be able to put it into your phone with it working.
2) You should be able to remove the memory card from the device and put it in a different device (such as another phone or PC) and have it still work like normally.
The problem with Windows Phone 7 is that it breaks these two rules.
1) Many of the higher rated MicroSD card flat-out don't work on WP7. This is because of the method WP7 uses to read/write to memory card. You can find more specific details on why this is but I will just keep it simple. There are many user-created lists which list which MicroSD cards do work with WP7.
2) You can NOT hot-swap your memory card once it is inserted into phone. Why? SD stands for Secure Digital which means there is a security aspect capable on the card. Microsoft takes advantage of this in WP7. Once you put your new card in your phone automatically reformats and locks it down. If you then take out the card and place it in another phone or a PC it will not be recognized, almost as if it is invisible. And the worst part, there is nothing* you can do about it. Once you pair a memory card and WP7 phone they are joined for life.
Why does this suck? If you buy a 8GB card now you simply can't upgrade to a 16/32Gb one down the road without losing all of your data and having a useless MicroSD card. The old card would become a better Frisbee than data storage device. This is why most WP7 phones don't let the users have access to the memory card. Microsoft knew this would happen and thus pushed manufacturers to not have the card easily accessible. There is even much talk that the memory card in the Samsung Focus was meant to be glued to the phone to prevent swapping but somewhere along the line that idea was scrapped.
* Note: Technically there is ONE thing you can do. If you own or have access to a Nokia N8 phone it can read the locked down MicroSD card and reformat to something any device can recognize. Essentially undo the problem. But how many people have easy access to one? The answer, almost nobody.

You're wrong. It has nothing to do with what you said. Lol @ breaking rules. They aren't breaking anything...
SD Card DRM is in the spec, it is only given to people who license it. That's what WP7 uses. It's locks down the storage system with a DRM key and that's why other devices (barring Nokias) can't see it - most SD Card clients don't support SD Card DRM.
Nokia (Symbian, and maybe Maemo, but I'm unsure on that) is the only other mobile OS that supports it, and that's why it can reformat the card (but cannot read any data on it, of course, since it doesn't have the decryption key). When you power on the phone, the WP7 pre-boot environment unlocks the card via a key on the device the same way you unlock an encrypted system drive on a PC. If a device cannot supply this key, they cannot mount the card.
If you swap the card, you have to hard reset the device because the storage is spanned and the decryption key on the device no longer corresponds to the SD card in the device (but due to spanned storage the device would malfunction even if it were to boot up). The new card is encrypted and added to the pool on a hard reset, and the [new] key is put on the device so that it can be mounted when the device is powered on.
It's pretty damn simple, and has been written in plain English in many threads; yet people still FAIL to understand it.
Have you ever thought there must be a reason why they call them SECURE Digital Cards? Or did you think Secure = taking it out one device and just plugging it into the other and taking the data off of it?
The Storage in WP7 was never meant to be swappable. Microsoft has always said it would not be. It's your own business if you want to play around swapping cards like Russian Roulette.
As far as which work with WP7. It requires higher Random I/O speeds than most SD Cards provide, and that doesn't correspond to Class Type. Also, a card can work fine for sometimes weeks at a time and then start to fail, so replacing it yourself is at your own risk.
And most manufacturers and carriers will void you warranty if you mess with the SD Card.
In that respect using memory cards is nonsense on WP7.
If you cannot do what you want with this, what was a rule and still is a rule on the market today,
they should just build devices with inbuilt memory like iPhone and don't talk about memory cards anymore. That would be simple.
Current situation is a mess.
So what cards are compatible now? I Googled it and the first response was 'San Disk Pulls WP7 compatible memory cards' and I figured that wasn't a good sign.

they only pulled it because MS wants to do official testing and release an official list.

It was a figure of speech. I know Microsoft didn't break any real "rules". This is what I posted:

When I said "rules" I implied "expectations". Microsoft did nothing wrong, outside of communicating with the end users, with how WP7 manages MicroSD cards.
And I clearly know why certain MicroSD cards will or wont work. I just didn't feel like explaining it because it would take a lot of time.
It's time to start expecting people to use these technologies in a secure manner.
The media industry does not support platforms that leave them open to be attacked by software pirates.
Information is power, and no one likes their info stolen.
There are many reasons.
iOS phones encrypt their storate. And the reason why they don't support external storage cards is probably the same reason why Microsoft uses the SD-DRM and encrypts the WP7 storage.
I don't know how Symbian handles its storage, but I'm pretty sure that OS at least supports Encrypting the file system on SD cards. It supports pretty much everything ele.
Right, let me give my own perspective on this.
Until recently I was a WM6 user. I regularly upgraded my phone, and the last one was an HD2. WM phones never came with any real amount of storage, just a piffling amount of internal memory (what, 500MB?). I was therefore faced with the added cost and hassle of having to purchase a memory card and insert it into the phone. This was a bit like buying a PC without a hard disk and having to buy and install your own. It was an added hassle and expense.
Once you had your SD card inserted, you were then faced with the decision of where to store the data for each of your apps. Take email - do you store all your emails and attachments on the internal memory, thus using up a good chunk of that precious resource, but having it work quickly, or do you store it all on the SD card, where there's a lot more room but it's slow and clunky, and if anyone steals your phone they can pop the card out and get at the data? When you install apps, you're again given the choice of where to install it. Do you go for the speed of internal storage? Do you put it on the SD card, knowing if you ever pop out the card, your app will be unavailable? Decisions, decisions.... Too much damned complexity. The average user shouldn't be faced with these choices, if I install an app, it should just go on the phone wherever, period.
Not only that, once my card was in there, I never once removed it. The majority of my apps were on it, my emails, and all my media. I totally filled it with media. Popping out that card would more or less break my phone. My apps wouldn't work, my emails would be missing......so I never did. Nor did I ever use it as a mass storage drive....because there was never any free space on it. Instead I had a 32GB USB memory key hanging from my keychain - that was my portable mass storage solution.
Not only this, if I wanted to put media onto the card, I had to connect to the PC and drag and drop my stuff directly onto the phone. What a hassle! Doing this didn't optimize the size of the photos for the phone's screen. It didn't drop the bitrate of my mp3s, it didn't convert videos to the right size and format. All that had to be done manually, and I never bothered, so my media took up a lot more room than it had to. So inefficient.
So, given that I never removed the card, and that doing so would hose my phone, and that it was always full, so never got used as mass storage, and that it was insecure, and an added expense and hassle, and putting media on the card was a manual process, what would I have done in a next generation phone to cure all these issues?
Well, I would have made sure the phone came with plenty of onboard memory, and I would have removed the distinction between internal memory and the "card" so it was all one storage container. I would have secured the memory so even if it could be removed, the data couldn't be read in another device. I would have made sure the memory was fast enough to deal properly with a modern OS. I would automate the process of converting and downsizing media by using software on the PC to automatically perform those tasks. I'd also make the process wireless and fully automatic. I'd.......oh wait, that's what Microsoft already did in WP7.
So I'm happy, even if you lot ain't.
I just got 2 Focus's for the Wife and I. Using the SD card sticky in the Focus forum here as a general help, I purchased a PNY 8Gb C4 for the Wifes, and a Patriot 16Gb C2 for mine (Frys, and the Patroit was the last one in the store from the Display! No one buys C2 anymore).
The back overlay on both devices mentions memory cards, and quick startup quide shows you how to install them and what happens if you remove them.
I put the Cards in last night (phones just arrived yesterday), formatted (hold the Power/Camera/Vol Down at the same time, answer questions) and in a few seconds each system was formated. Both are working fine right now.
Right now though doesn't mean much, many in the SD thread are having issues after several weeks, though it seems it more prevalent with the 32Gb cards. YMMV...
What I find goofy about the whole thing is that it has been stated that 7 needs random read/write, which is not measured by class rating, and can vary even within the same type of card, but very few people have posted numbers showing that they tested their cards at all before gleefully sacrificing them to the hungry maw of the Focus. Seriously guys, do more testing and post more numbers before rendering your cards unreadable to a PC. It'll help us all to better understand what works and what doesn't.
This bites.. I always knew that the card inside the wp7 was secured, but I always had faith in the power of this forum. Especially in recovery situations. Now I have lost a lot of irreplaceable data, like dozens of pictures of my young child. It seems I had a little too much faith.
Thank you for this information. it was very helpful. I have already moved away from Windows phones to android, and am going to start using nandroid. Hopefully this won't happen again.

How can i get data from a CF card into my WinMo phone?

Hello,
i need to get data from CF cards into my phone. The problem is that it has only a micro SD slot and isnt USB host cabable. Are there Adapters for that?
The option of putting a microSD card into a CF adapter is not an option. I dont want to buy a new microSD with 64 GB and the needed speed, i want to use the CF cards i allready own.
So any small cheap and mobile solution would be great.
- best probably an adatper from CF to microSD
- or some WiFi Cardreader
- or a cardreader that can act as USB host
- a cheap CF imagetank that can send selected images via bluetooth, but i dont think this would be cheap
Any new products out there that could help me?
Hey guy you can used card reader to transfer data or use wifi app such as airdriod to do this.
.
Thread moved to Q&A due to it being a question. Would advise you to read forum rules and post in correct section.
A quick and simple way would be to just bluetooth the files over to your WinMo via the PC?
Alternatively, you can always use webservices like Rapidshare/Megaupload/Drop.io to upload+download the files on your phone (hopefully wifi-enabled)
These are methods which do not require any investment!
I do not have a PC, im mobile, on the street just my camera, my phone and whatever small gadget can help me get the files over.

[Q] microSD help

Hello kind people. Seens i had my Transformer ICS i never bothered to use microSD card but no i travel a lot and watch movies on it. So recently i bought 16gb class 2 microSD card tried to use it in the microSD slot. Yes i formatted it in to Fat32 and it works perfectly well with card reader in any PC, but when i put it in the tablet it recognises that there is a microSD card in but it takes some long time and it does not see anything on the card, i can create folders and copy small files, not cut and past. After i do that i put the card in the PC and there is no any files or folders that i created on the tablet. But if i put it in the dock via SD to microSD adaptor it sees everything that on the card. Can some one suggest any answer to my troubles. Thank you all

** What brand?
** 16 GB with Class 2 can be very slow very often.
** In some cases, windows can do funny things to cards formatted on windows, when used with android. A very good time-tested software for formatting sd cards is from Panasonic here: http://panasonic.jp/support/global/cs/sd/download/index.html
Try formatting with this.
Good luck!

Also try to have the Transformer format the card instead of using Windows to format the card. There are probably several little differences in formatting with Windows versus the Android device. For instance a movie that is over 4GB in size or something similar to that may or may not appear.
