1.) I bought a 16GB SD card (Patriot) at Microcenter last week. Everything was fine until last night I noticed my program were blank. I then see the card is not mounted, and will not mount period. I removed the card and put it in my laptop where I could see the files. I did notice the card was locked read only, even though the card adapter was clearly not set for it.
Is there a set list of SDHC cards that can only be used? Do I need a certain speed card? Any ideas why this card refuses to mount suddenly? I can't even format it in either the phone or my laptop.
2.) I have a car stereo with AUX port I used for years with ipod. Plugged in the phone to play music and it worked fine for a day or so, then either my speakers (all 4) have fried, or the stereo itself is fried. Radio and CD both produce crackling static, then silence. The timing seems odd, so it does seem that connecting the phone to play music damaged it? Ideas or thoughts anyone?

Edit: About the SDHC card, I have put it in the laptop with several adapters making sure the lock tab is not pushed down. Even tried the tape method. Card is locked, and nothing seems to unlock it. Personal data such as photos (I think of just the cat) put there is an Excel sheet that has invoicing information for my work, as such I have to delete this before returning. Would a magnet work? I guess in the end not too critical, but still.
Edit #2: Found someone else over at Android Central who had the same exact problem with the same exact card, the Patriot 16GB SDHC class 4 found at Microcenter. Suffice to say I am just going to exchange it for a SanDisk. So does anyone have an idea how I can erase the existing data? Would using something like Ubuntu do the trick?

Ok I have an 8GB card for my Tilt but i just bought a 16GB card and I want to transfer my files from the 8gig to the 16gig. The problem is my pc (HP a230n) can't read either one of the cards. I know that it's because they are SDHC cards but I can't seem to find anything online that'll give my pc the capability to read them. Can anyone help me out?
how are you putting the cards into the pc
via a reader and adapter or maybe using the phones mass storage utility??
please enlighten us
The card came with an adapter so that's what I'm trying to use.
try using the phone as the reader u should get a pop up asking if you want to use as a usb mass storage device
hopefully the pc with then pickup the card
also try using on a different pc with both the adapter and the phones usb utility
I've done it that way before but it's a lot slower like that. I want the cards to actually work with the pc directly. Once I'm done transfering everything to the 16gig I'm gonna have the 8gig just sitting there so I figure I'd put it to use but it's kinda hard when I have to put it in my phone to use it.
I just finished transfering all my files to the 16gig through the phone but I would still like to be able to do it directly through my pc in the future.
then try and find a ppc tool thatll format the card
we know the ppc will pick it up but not the pc
THIS little bastard did the trick perfectly. No need for a firmware update.
job well odne then
I am about ready to buy a 16 GB class 10 micro sdhc for my Nexus One. Any ideas if this is a good card. Will it be totally compatible? And will I be able to transfer at the advertised speed? Does anyone have one of these?
http://www.newegg.com/Product/Product.aspx?Item=N82E16820139121&Tpk=SDC10/16GB
I think a class 6 is enough. Don't see a need for a class 10.
If HD recording ever gets adapted....or divx playback I'm sure the extra speed wouldn't hurt. The question is whether or not to nexus 1 will utilize it.
My class 6 micro sdhc card is only transferring at 2 MB/s through the data cable from phone to computer and vice versa. Either my card is taking a **** or something is wrong, it's definitely not 6 MB's.
So if I can pick up a class 10 micro sdhc and actually being able to copy music onto my sd card mounted in my phone at 10 MB/s I would be really pleased.
I just pulled the my micro sd card out of the phone and plugged it into a micro sdhc to usb adapter, and I transferred music onto the card through the adapter and it transferred at 6 MB/s no problem. So there is nothing wrong with my micro sd card. WTF Has it always been this way.
What I mean is: while the card is in the nexus and when you transfer music to the phone through the data cable, is the nexus only able to transfer at 2 MB/s? Through the Data Cable?

Yup... I've noticed this too. It was the same on my G1. The card is capable of 6mb/s but the phone can only do 2mb/s through the usb...

That really is a bummer, I don't know why in the hell I haven't noticed this before. It really doesnt matter to me how fast my sdcard card is then. Because I never ever remove it from my phone. So a class 2 is pretty much all you need because that is the only speed the phone will ever transfer at.

Unless you're rooted and run Apps2SD... but yeah, I'm unrooted on my N1 and plan on staying that way and I don't understand it either. Maybe there's a way to speed it up with a software update?

Let me get this right. You have your micro sdhc card in your phone. Then you plug the the usb data cable into your phone, then you mount the phone to your computer by the pull down menu on your phone, then you can transfer music to your sdcard at 5.6 MB/s? Are you sure about that? And you have to be able to transfer music off of your phone onto your computer at the same speed I assume.
The reason I am mentioning all this is I partition my sdcard to 3 partions fat32, ext3, and swap. So another words I had to transfer everything off of my sdcard, and transfer it back on after you created the partitions. And if you have 6 gigs of music this can take a very long time. Then I formatted my sdcard again for 1 partition and had to do everything again. At 2 MB/s that is a very long wait.
I guess I could of just pulled the sdcard from the phone and plugged it into my adapter and transferred at 6.0 MB/s. This sucks you would imagine the nexus could do this np.
It's amazing you can do it at 5.6 MB/s to your phone. Maybe you got a better version of the Nexus than I did?
Don't forget, there are two sides to the issue, the phone side and the computer side. Perhaps you could try another computer? I average 5.5MB/s from my Linux workstation.
Are you going through an old USB hub or direct to the computers ports?

Direct to the computer ports, and I am running windows 7, maybe I should try my ubuntu pc.
The phone's USB interface might be the limiting factor; when the phone is communicating directly with the SD card, it may be able to use its full potential. This would matter when you're recording video or using Apps2SD. Meaning that class 6 cards aren't necessarily pointless.
Also note that class 6 means 6 MB/s write speed, not read speed (as has been kind of said above - just waned to make it clear) - if you're reading it at 6 MB/s, that doesn't necessarily mean it's working right.
I don't have one to test with, sadly.
What I wanna know is where are the 32Gb Micro SDHC cards??
I have a 16GB a-data micro SDHC transferring via usb at speeds between 2-3MB/s
when i put the card in a card reader instead of the phone, xfer speeds are between 5 and 8MB/s
I'll try copying files to SD via wifi and bluetooth. if either of those are faster than 2-3MB/s, then the usb may be the bottleneck.
Are you guys benchmarking , or just going by screen stats ?
dang i didn't know they even made class 10.... I bought a class 2 16gb when they first came out, it just died actually so i'm waiting for sandisk to replace it. I've considered a class 6 but i don't see the point with 32gb cards coming out soon.
I've seen pre orders for late april on the 32gb's. other then that you can get one now if you import it from asia.
I am just wondering exactly what speed the Nexus One is capable of transferring at? Cause I can see alot of people are having the same problem as I am having with higher class sd cards. I know for a fact my class 6 sd can transfer at 6 MB/s and it does when its not in my Nexus One, so it's either the Nexus or the Data Cable that is eating the other 4 MB/s, cause I am only cable of transferring at 2 MB/s and no more.
Now when I talk about transferring I am solely talking about transferring music or data off of my Nexus to my computer and vice versa. I want to think it's just my Data Cable. But I wish I had this answer, I will today for sure.
Now is there a low speed Data Cable, maybe that is what Google sent me a low speed one, and maybe this 1 penny high speed data cable might solve me some problems.

I just got an Epic 4G and while the 16GB microsd card is plenty of space for most stuff, once I start putting alot of converted movies on there, it will disappear fast. Now, I had another 16GB microsd card, along with a class 6 8GB card and a 4GB card, all micro-sd. Is there any way at all to plug something into the micro-usb port on the top of the Epic and have a micro-sd reader at the other end and then have the phone be able to mount the extra/2nd micro-sd card so I can then play movies/etc from there rather than having to constantly pull off the back cover and swap cards?

This seems pretty impossible, i looked up some info on the subject and
well... all results were negative
how hard is it really to swap out that little card on the back though! i mean come on, years ago we had to swap out vcr tapes for ONE movie!

I've got a 10" SuperPad running 2.2. (Flytouch2) It has 2 regular usb ports and will read thumb drives just fine. (Ud0 and ud1)
Leads me to believe it would be kernal based. If you has a female usb to microusb male and a usb micro reader, as long as the kernal had support I don't see why it couldn't be done.. but the devs would need to confirm or deny.

it could simply be a driver issue. i may try to splice a few cables tomite.
On my SGS3 (Verizon, of course), I get audio skipping when playing music from my 64GB SanDisk Ultra Class 10 micro SDXC card via MHL, but it plays fine via the 3.5 mini jack or if the music is on the phone's internal storage. The card is formatted to FAT32 since custom ROMs don't read exFAT (I am using SynergyROM r73).
I have also tried a Kingston Class 4 32GB micro SDHC card and the exact same problem surfaced, so I know it is not an issue with the card itself. I have tried it on multiple output sources (TV, car head unit), and the issue persists. It also occurs regardless of the program used to play the music.
This is the only thing keeping my car audio setup from being perfect and I am desperate to get this resolved. It makes no sense to me unless it is a software issue (and the SynergyROM thread is too crowded to get help in, as I've tried and the posts get burried). Is this a ROM issue such that I need to go back to stock? Software issue? I'm lost.

Yes, but I don't think that could be the cause regardless since it works fine over MHL from the internal storage. It's only when reading from any external SD card over MHL that I get issues.
That's weird, I have two G3s and both play audio perfectly from my sandisk 64 gig cards.
One of the phones is running Liquid R5 and that one doesn't play video very well from MHL (the external screen flashes all the time) but even that one plays audio just fine from my card.

i formatted a sandisk 64gb micro sd to put into my tablet and start copying files to the micro sd via the memory card reader, there is nothing on the card prior to transferring the files but as soon as the green bar goes up it cancels and gives a 0x80070037 error with unrecognised device and prompts me to check the micro sd for errors, i proceed to do so and it finds nothing, i retry a couple of times and i get the same error, i try different memory card readers and cables and they all give the same error.
i then attempt to transfer my files while the micro sd is in the tablet and surprisingly it's transferring the files fine, i'm a bit confused by that and i was wondering if anyone can give some hindsight as to what is going on?
there is obviously a problem with the micro sd because i can't get any data on it while it's in the memory card reader and i will have to get a new micro sd card eventually, i'm not buying anymore sandisk memory after this, reason why is because my 32gb micro sd also by sandisk has the same problem, both brought within 9 months of each other, that's £60 down the drain, for now the 64gb will have to do till i buy a new micro sd card but this is just ridiculous, i wasted 4 hours trying to sort this problem out with no progress and i'm exhausted, any ideas or solutions would be helpful.
i've tested my usb ports extensively (so it can't be the usb ports causing the problem), and formatted the sandisk micro sd cards multiple times (to no avail), i've tried 2 different usb drives, and 3 different micro sd cards from samsung and a no name brand and they transfer the same data fine, but as soon as i plug in the sandisk and transfer the data to them i get the errors so i've pinpointed out where the problem lies, i just want a solution to sort all of this out so any help would be grateful.
if i get any changes in the situation i will update in this topic.
Just a update, contacted amazon and will be getting a refund for both micro sd cards, thanks god for that, won't be buying SanDisk ever again after that.

Unreconized device is it has lost connection to your tab. I've had the same problem. Installed a new usb 3.0 card and plugged into that, and the problem went away. if you watch my computer you will see your device disappear and reappear.

i tested out both micro sd cards on a memory card reader not from the tablet and the data transferred fine when the micro sd card was installed on the tablet, amazon have agreed to refund the 64gb sandisk but not the 32gb micro sd unfortunately i'm going to buy a usb 3.0 memory card reader and see if i get better results with the 32gb micro sd, not confident that i will though, just going to use the 32gb for something else till it dies, nothing else i can do with it, they can't replace it because it's over a year old and i left it too late.
just plugged in the 32gb micro sd card now and the memory card is not disappearing and reappearing in my computer like you said, the only time i get problem is when data is copied to it then the device disappears.
