Questions on MicroSD

Hopefully an easy question for someone to answer! Will the Kaiser read a SanDisk 8GB MicroSDHC card?
On another point, I have a 4GB MicroSD that no device can read anymore. I cannot reformat it as it does not show up on the device (PC, PDA or anything!). Any ideas?

1. yes
2. ??

1. Thats what I have
2. Broken card, throw it away?

Hmmm
1. Been running that for a while.
2. Make sure your PC Reader can support MicroSD before deciding that the PC can't read it (hint - putting the microSD card into the Sandisk larger shell does NOT make it a regular SD card). If you are POSITIVE your computer can read a MicroSD card, and it doesn't register, then toss the card.

Corrected above - the adapter DOES turn a MicroSD into an SD, AND a MicroSDHC into an SDHC. But, not all readers can read the HC cards (4GB and more).

This has been asked many times and the answer remains yes (the same for the 16 GB version - I use one with my TyTN II).

When you say 'anymore', whats changed? Are you still using the same microSDHC -> SDHC adapter that the card came with and a suitable SDHC compatible reader when testing it on your PC? If so, it's time to get in touch with the company that sold it to you for a warranty claim.

I had a similiar problem. While moving some music over to my 8 gig SD brand card it failed after about 3/4 of the files and then dissapeared. I've tried soft reseting and popping the card in and out and I can't get my phone to recognize it.
I need to get a new usb adapter b/c the I don't think the one I have is hc compatable (it's a few years old) so I have no idea if my computer will recognize it directly. Does this sound like a card issue or phone issue.
Running ATT WM6.1 minus bloat with a few programs (all of which have been running for a week or so no problems). Sorry to hijack, I just didn't want to open a new thread and get flamed.

i got a 4gb micro SDHC, its a sandisk. i got it to upgrade from my 2gb sd, i have read that the HC cards (sorry if the card is in the acronym) are compatible with tytn II's.
it wasn't with my original rom, and now i have tried to new roms both of which wont recognise it at all. is there anything i can do?

Did u try to format the card using fat32?

I just put a 16 gig Sandisk in mine last week I found on Amazon.com for about $65. Works fine.

New owner of Kaiser,I had Artemis and Touch so far,now I want to buy 4gb micro SD card (made by Kingston) for Kaiser, Has anyone had any problems with 4gb miscro SD?Will it work smooth and without any problems?
Thanx in advance

Since this morning my device is telling me that no Storage Card is inserted. I didn't change anything and the SD has been inside the device all the time. I bought the device around april 2008. I still have to test the card on my PC at home, but I wanted to check what my chances are. What is a bigger change? That the SD card just died on me or that my device has a hardware problem?
Funny thing is that yesterday I flashed to a diffrent ROM. I did a hard reset, still no luck. Flashed with an entirely other ROM, still no luck. So I am hoping its just the SD card that broke. Would be strange if flashing a ROM would cause the SD card hardware inside the device to fail the next day.

Try to reformat the sd card with fat32. That helps sometimes.

My laptop has a SD reader but it doesnt even map the card to a drive like it usually does. Any tools that I can use?
I already ordered a 8 gig MicroSD which should arrive tomorrow.

I'm not ready to blame my Tilt for my mSDHC problems but it sure seems like theres a lot of posts out there here and other places about people having memory card problems with their Tilt. I"m going to try again but if another memory card fails I'm sending my tilt back and hopefully I can demand to at least upgrade to a Fuze for a cost.

Funny this thread came up as my 4 gig card crapped out on me recently and is unrecogniseable to any device after running the sdhc cab on it. But yea, 8 gig works just fine. Using a 16 gig now with smooth sailing

[Q] microSD card help.

i had no real idea where to put this, so since i will be using it in my nook i figured id try here.
Wintec microSD class10 16Gb
i bought this new micro SD card for my nook. i put it into my card reader to format it (fat32 is the only option).
when i quick format it goes fine, then i try and put stuff on it and i get a dependency error and windows explorer crashes (not responding).
when i do the regular format, it gets all the way to the end and says "fromat can not be completed" and windows explorer crashes (not responding).
try it in another computer with the exact same results. is the SD card bad? i havent done anything with it. i took it out of the package and straight into the card reader.
bought it from newegg. should i contact newegg first or wintec?

You aren't the only one that has had problems with that card.
I have one and it works, but speeds are class 4 at best. A little under that actually.

Differences between booting from uSD and emmc?

Hey everyone,
I currently run CM7 off an SD but I was wondering if there are benefits to replacing the stock os on the emmc?
Are there any speed differences or technical pros to it?
Thanks for the input! This is a really fantastic forum!

From my experience the booting time is almost half if using emmc version. (SD card version ran on a class 4 card). After booting the performance is almost same. You may get better boot time for sd card using a class 6 or class 10 card.

I dont have an answer for you as i picked mine up yesterday and decided to go the SD route at the start i am curious on this question myself.

Well from my experience, running from the SD card is very smooth... so for ease of use i highly recommend it for a first go.
I have a follow up question- for some reason my macbook recognizes the second partition of my sd card but my pc desktop does not. I am referring to the partition generated for storage by the CM7 installation process that allows storage on the data card simultaneously.
Any ideas why this would be?

I use Macs and Windows machines rarely (and I am guessing you run Windows on the desktop) but my guess is the ext4 partitioning that CM7 uses.
I seem to recall that working- at least somewhat- on Mac but not on Windows, but I am not positive.

i chose sd, because it's super easy to backup my sd card as an image by popping it into my laptop. I can then burn that image back to a sd card if i want to try a new android build without messing up my default android install. I can always boot into the original nook os if i want as it is unmodified.
i used a class 2 and it was pretty slow. moving up to a class 6 and 10 has really helped and i don't notice any slowness.
i have not run off internal memory though so i don't have a baseline to compare.

eMMC is faster than my class 2 uSD cards, and it's easier to swa stuff back and forth from a computer/phone/camera/whatever with a removable uSD.

Cool, I've been wondering about this myself and was about to make this same thread.
I was concerned because I get a ton of force closes running off the SD, and I wondered if that was a problem that would be solved by going to eemc. Or if somehow I've made a mistake setting up my card and that's the issue. I'm very knew to this whole scene, so I'm still a bit scared of rooting at the moment and would love to iron out the problems I'm having with the SD booting. Things run fast, and fairly smoothly but eventually something will force close, like Market, and then Google Frameworks and then pretty much everything will refuse to run after I tap their icon. Forcing me to restart. Also, some things, trying to download new skins for Beautiful Widgets is impossible. Only get force closes.
I can't figure out if it's anything in particular that causes it to spiral out of control. And what makes it more annoying is this is my girlfriend's new Nook, I'm trying to get it set up for her to work as smoothly as possible. If it was just mine, I wouldn't be as bothered by messing around and trying different configurations and whatnot. But I know she won't be as patient and tolerant of these issues and won't want to keep bugging me with every problem that pops up.
Would you say this is likely a localized problem on my end through some fault of my own? From this thread, it seems people are having pretty great experiences with the SD method. Which might be reassuring. I think I'll do a backup and start from scratch this evening.

@JRSly: What type of uSD card are you using. I was experiencing the same problems you had with booting, force close, refuse to run, thus a final restart. After swapping out four different types of uSD cards, SanDisk (class 2 and 4), A-DATA (class 6), Patriot (class10), I finally deteremined that the Nook is very picky about the type of card. All the cards work fine in my digital camera or PCs, but the A-DATA and Patriot are slow and often hang in the Nook. I am now using the three Sandisk cards with no problem. I recently updated to Nookie Froyo 6.8.5 and it runs great on the SanDisk cards. Just for the test if it will run faster on A-Data (class 6), wouldn't you know it starts to hang and FC just like before. I guess I'll use the A-Data card in my digicam. Try a Sandisk card and see what happens. I even try one of my old Sandisk 2GB card from my Blackberry which is unmarked but has a class 10 performance when measured.

I'm very new to this... and I keep seeing emmc.
What is this? Internal memory?

I feared that this might be a possibility too. My first attempts were with a little 2Gb card I'd had lying around and it didn't work very well at all. I couldn't get past installing Gapps for all the force closes. The next day I went to Target to get a larger 8 Gb one so I could also play around with Honeycomb, it's a Class 6 Lexar card. I started over last night and tried a couple of attempts at wiping and burning the image and inevitably ran into the same problems. It looks like a crummy(at least in terms of what the Nook likes) card is a distinct possibility. I'll give Sandisk a shot.

Yup. (I didn't get it either.)
Since MMC is a sibling of SD cards, it's basically dedicated internal SD storage with a controller.

You got it in one.
sd card is self explanatory, of course, and emmc is the internal memory of the NC.
The only DISADVANTAGE to running on emmc is that you lose the stock B&N version of Android.
Other than that- it boots a bit faster, may run a bit faster and be less likely to have force closes and similar problems.

[Q] Problems with installing cm7 to booth from 16gb class 6 microsd card

I am a newbie, still on original nook firmware think its 1.01
I am having trouble trying to install cm7 on a 16gb microsd card. I had a look in XDA and there are a few people having the same problems awhile ago, and then there are some who have managed to do it. I have trawled thru quite a few pages int he foru but can't seem to find a solution. Anyone here has any luck with installing cm7 to boot from a 16gb microsd? Any comments would be appreciated.
My problem seem to be, after i imaged the microsd and then copied the update night;y cm7. zip file across, the nook booth from the microsd but and setsups but then just hangs after superfiles(?) have been installed, whereas the guide saystehat it will ventually go to a blanks screen, which mine never does, then when i force shuitdown and reboot, it installls some android files but when it reboots after that it either hangs onthe ANDROID_ screen (keeps rebooting over and over again) or it goes to the cyogenm7 graphic screen and keeps rebooting to the startup screen.
Thanks

Try a different SD card, preferably 8G or less. Quite a few cards don't play nice. If you can get CM7 installed on a different card but still want to try it on your 16G card, you can image it over from your other working card. You'd then need to expand the 4th partition to reclaim the space then. It may work, or you may get random quirkiness using that card with force closes here and there.
I'd make sure to get a genuine SD card from a reputable dealer, not some dodgy one off Ebay. I have found Sandisk to be very reliable, and generally a cheaper Class 2 or 4 card will work better due to higher speeds with small random block r/w.
Good luck.

[Q] [HD+] Which types of SD cards are best for my situation

Hi all, a few questions here if you don't mind. I'm a recent owner of a HD+ and have had a great time with it but I am ready to get CM on it now. At first I wanted to dual-boot using either Hybrid or Pure but now I think I'm going to just to EMMC.
I have a lot of comics I want to store, if I'm using EMMC is there no problem using a 64gb class 10 card? From what I've read it seems that class 10 cards only cause problems if you are booting from the SD card?
If I do go hybrid or pure, it is better to use a class 4 (32gb max?) card for this correct?
I do think that I am just going to go the EMMC route, does doing this erase everything already on the Nook or just the OS? (I need to remove any other media myself?)
Thanks a lot for reading all that, and any help is much appreciated!

Installing CM into EMMC will erase every userdata and OS on it.
As long as you want to just store files on it, you can go and get the 64GB one.
My experience with those classes are that, that Class 10 is only fast for big continously written files like videos or songs in high quality.
Lower classes or non classified ones are often MUCH faster at tiny to medium sized files with much access on different adresses.
Backup everything, do a backup via SD recovery, then make factory reset via SD recovery and install CM10.1 plus GApps.
I am a HD+ owner since today and I have chosen to go directly to CM10.1 stable emmc, because I already had experience with SD ROMs from my old HTC HD2 (RIP) and I hated the lags and everything...
(I hate every vendor made bloatware that is stacked onto Android...)
The only thing I can say after my first day with vanilla CM10.1 is, THIS TABLET+PRICE+CM10.1 = AWESOME :laugh:

Hello,
I hope you're well, and I hope you're enjoying your Nook. Installing CyanogenMod on the Nook was the best thing I ever did (at the time Stock didn't have Google Play), so I hope you too enjoy CM.
Personally I do believe that installing CM10.1.3 (stable) on EMMC for general usage is the best way to go. I'd avoid CM10.2 for now, until a RC or stable version is released.
If you're running CyanogenMod (CM) on EMMC, there should be no problems at all as regards to what SD card you use. The storage size or class should not matter when on EMMC; although higher class is tied with better performance. The whole best SD card to use is 4GB class 4 arose when we didn't have the EMMC method of installation; back then we used to boot/install the whole CM on the SD card. Now, I don't think your SD card is as important - anything is a go, after all you're using it for storage only.
If you do go Hybrid or Pure, yes a class 4 SanDisk SD card is best. 4GB is also recommended, but you can go higher if you desire. If you do install on SD card, I'd recommend going Hybrid and not Pure. Out of the two, I'd just go EMMC (EMMC > Hybrid > Pure). However, if you do install on EMMC, everything will be erased on your internal; this includes your stock ROM, and all data/apps. You will however have all your B&N books saved on the B&N cloud.
All the best, any more questions please feel free to ask.

I back this statement.

Thanks for your replies guys!
You pretty much cleared up any confusion/questions I had regarding this. Pretty sure I'm going to just do EMMC. Plus even with the GooglePlay on the Nook now, I still have a lot of games that aren't compatible or are from Humble Bundles, so I don't think I'll have much use for stock.
One more question and I'll leave you guys alone. I have a USB MicroSD card reader I got somewhere years ago. Am I to assume the newer microsdcards won't work with this? I'll have to keep an eye out for a good deal on both. Thanksfully black friday is only a month away in the US :laugh:

Haha, no problem at all! We're glad we could help.
Regarding your MicroSD card reader; it shouldn't be a problem, as SD cards haven't changed over the years - only the storage capacity. As long as your card reader can read MicroSD cards, and can write to them, you should be good to go. Of course however, I don't know what card reader you have, so there could be problems. I'm assuming it should be safe though.
All the best.

Nope, SD-Card Readers aren't compatible with SDHC/SDXC Cards as there are some differences.
SDHC-Cardreaders are compatible with every type.
SD-Reader --> SD -/-> SDHC/XC
SDHC/XC-Reader --> SD --> SDHC/XC
SD-Card = <4GB
SDHC-Card = >=4GB to 32GB
SDXC-Card = >=64GB to 2TB

Thanks for the info! This is the specs of the card reader I have
"Versatile — 9-in-1 USB card reader that works with SD, SDHC, MMC, MMCplus, MMCmobile, RS-MMC, microSD, and miniSD, MMCmicro"
Seeing as it lists the SD and mircosd compatibilities separate, am I right to assume it cannot read the micro sdxc cards I am going to need?

As it supports SDHC, your reader should be good to go with microSDHC cards.
