pros and cons of flashing a rom onto device or run from sd card?
am I asking this question wrong?
I guess this question has been asked several times. It's very easy to flash back to stock and the NC seems to be unbrickable, then I think you can try both to know which one you like best and get your asnwer by yourself.
Regards!
I'm very much a newbie (haven't even USED the NC yet), but:
Pro: SD card approach is extremely clean; you can leave the stock internal "eMMC" ROM alone, UNROOTED, and boot off it again at will, just by removing the SD card.
Pro: You can boot off different Android distributions as easily as swapping SD cards.
Con: Many people find SD card booted operations significantly slower. The sweet spot seems to be using a Class 6 card? (Class 10s are faster but not as many good reports from what I've read.)
I don't think you will realistically see any difference between class 6+ cards. I doubt the Nook itself can perform at true class 6 speeds, so the card isn't the weakest link...

Hey guys,
I've been having a great deal of trouble with my cheap Transcend 8gb class 6 card . . . spontaneous unmounts, lots of finicky behavior all around. Having the apps on the SD means the phone crashes, and the app permissions get borked to hell.
I've heard these are not very good cards (you get what you pay for in this case) and are known to have problems with the G1 . . . or the G1 is known to have problems with them. Either way, perhaps some of you can help me:
-Are the Transcends indeed "problem cards?"
-Has anyone had one, gotten fed up with the crashing, replaced it, and is in good working order?
-If that's the case, what are some known good cards I can get to replace it?
Thanks!
they are not problematic, they are just not compatible enough! Every device has issues with every other sd card no matter what. I been buying sd cards and I have had problems with these since the day they were born.
In my opinion, transcend are one of the more compatible sd cards. Funny thing is I use a sandisk on my phone and I always had issues with sandisks before on other devices.
First things first, Transcend are by no means a 'cheap brand'. They actually make some of the more expensive memory cards you can buy, and they are very good. My memory card is a Transcend, an 8GB Class 6 like yours.
The difference is that my one has never failed me. It's actually very fast. Furthermore, Transcend are known for making good memory cards. Maybe you just got unlucky with your one.
I ordered the A-Data class 6 to replace my class 4 sandisk based off raving reviews. I havent read much for negative reviews on the A-Data lineup, even though they are a smaller company
I had a transcend 8gb class 6 card that failed completely (can't even access from a PC). When it failed, and due to my apps to sc and other changes, my phone wouldn't boot without a card. I had to install the 128 mb card once I got home and re-update from scratch. When the transcend card worked, it was fast. I've used other cards of theirs in my cameras for a while now, and they've been very good. But this failure caused a bit of a headache for me. I'm at the point where if I see any problems with my sd card, I'll simply replace it to avoid worse problems. Wouldn't have helped in this case as I saw no signs before hand. If it means much, I'd try another transcend card again.
Sorry, didn't mean to bash Transcend undeservedly. So maybe it's just an issue particular to their cards and the G1?
Thread moved to Dream Q&A, please post in the correct place; not dev related.
i went through 2 4gb class 6 adata cards that wouldn't work at all after i partitioned them. phone would bootloop regardless of rom. it worked great if i left all fat32....very strange.
orange that should be a good card. if you have any way to put it into your computer and try to format it, via a usb conector ect. then give that a go. other wise it could be the rom your on, what type of rom are you using or is it stock?
Don't base your purchase decision on the Class classification. Sandisk's Class 2 cards have known to have stellar performances under ATTO.

Cyanogen Mod. Latest (4.2.12.2) but I've had this problem in previous versions. A friend's G1 has experienced similar problems with the same Transcend 8gb card, and I vaguely recall hearing warnings against using that brand w/ the G1, but perhaps I'm mistaken.
For now, I've deleted the EXT and swap partitions from the card and did a wipe so that all apps are running from internal memory. I haven't noticed any unmounts today, but last night the phone was unusable and this same sort of thing has happened before with the same card in both my original G1, and the warranty replacement (the warranty replacement was for an unrelated issue).
So I only have one right now that's in my phone so I'm thinking of buying one for the NC. Obviously I want to root so does the class matter?
I'm using a class 4 and it's fine for watching videos at 1000+ kbps.
Most seem to be Class 4 at the moment.
Also keep in mind that the class doesn't mean much, depending on who you buy it from. Class 2 cards from reputable companies like Sandisk and Kingston tend to perform much faster in benchmark testing and real-world usage than so-called Class 6 or even Class 10 cards from eBay specials.
Also, does the SD card have to be inserted at all times for the NC to be rooted?
No. The directions under rooting tell you to remove the SD card after rooting.
But I recommend a Class 4 card or better from any of the major brands. You can check NewEgg.com reviews for particular ones.

Thanks! I didn't read through the instructions all the way yet since I don't have my NC yet.
Just picked up my NC at Best Buy about and hour ago. I have it at home charging and I'm going to go get a couple of MicroSD cards.
Should I go for the Class 10, or is Class 4/6 fast enough?
Unless your running something from the SD card then I'd recomend at least a class 6, you'll get around 11mb/s writing time, otherwise both the ROMs for the nook (Honeycomb & Nookie Froyo) both support installation to the emmc, you can just flash them to your system with Clockwork Recovery.
tldr; if you can find a class 6 or higher for cheap (I got an 8gb class 6 for $12 off amazon) get it, if not you'll be fine with anything truly now.
I am currently using a Class 4 8gb, and have no trouble running apps or even Froyo off the SD card,
Basically if you are just using the SD for apps or holding data, anything should work i would recommend at least class 4 or better, if you are going to be running the a custom rom off the SD while some class4 will work well. I would still recommend class 6 or class 10, Faster is always better.
Posting this from my new NC!
I stopped by Frys Electronics after dinner and picked up two Patriot 8GB Class 10 MicroSD cards. Getting to know the Nook a little before I root and start with the custom ROMs. Gonna load Froyo on one card and Honeycomb on the other so I can try out both flavors and see which one I like better.
Hi everyone:
I have been running 6.8 from my Sandisk 2GB unrated card. Although unrated, the card runs relatively fast with the Nook as measured to my Samsung Captivate or Apple iTouch (2nd Gen).
First Card: I backed up the image from my 2GB to a 8GB A-Data Class 6 card. Now this is where the problem starts. The Nookie boots up but down is acting slow and sluggish. To the point it is unuseable with lot's of FCs. I tried buring a brand new image and it is the same. I also tried the card as a data drive max'ing it out to 8GB and also using it to record video in my digicam, no problems.
Second Card: I then bought a Patriot 8GB class 10 card and copied the image onto it. Even worse. It won't even boot or get stuck in the boot process on the "Customted Froyo" screen. Try other images, and the same things occur. The card also works fine as a data card.
Third Card: Third time's the charm. I got this card from Costco. 8GB, class 4. Copied the image from the 2GB to the Sandisk 8GB, expanded the partition like the others. Worked like a charm and runs even smoother.
My question here is:
1) Is the Nook picky about micro SD cards? Seems like the faster cards are having compatibility issues.
2) For people complaining about performance issues running off of the micro SD card. Could it be caused by compatibilty issues I've experienced?
FYI, I've been running "Customized Nookie Froyo" from my micro SD card for about two weeks now with no problems. This will be my daily driver. I get the best of both worlds, Froyo and the B&N image.
Something to think about
Evidently the NC is picky about cards IF you are going to run from them - which is somewhat more intensive than is intended for an ereader additional storage device.
There are existing threads on the subject, just search TITLES for "card" in this Forum only.
Summary - The Transcend 8gb Class 6 seems to be the favorite. Some Class 10 cards don't work correctly in Nook. A-Data makes great Desktop RAM and crap SD cards. Sandisk is a safe choice when on sale, their Class rating is conservative.
Patriot 8GB class 10
I have the same card and works great. Strange. I don't know why you are having so much problem.
Did you try a new IMg? .3?
i tried the following

I tried .3, 6.8, 6.7, and HC all with boot or performance problems. I have two Sandisk8gb cards now and able to run all images with no problem. Typing in HC right now.

Bad batch? I tried hc .1 .2 .3 no problem. I guess I am lucky.
I have class 4,6, & 10 cards in 8Gb, 16Gb, and even 32 Gb. Mix and match of brands from SanDisk, A-data, Wintec..etc. Only issue I've run into is using any of my 32Gb cards, they just plain do not work right. Whether I use them for just storage or even a ROM running from them they are nothing but trouble. One thing I have noticed tho is DO NOT format the card using Windows before burning an image. You are better off using a3rd party app to format the card, it seems to work much better. Or format them with Linux if you have access to it.
BTW as for the 32Gb cards they don't work well with much of anything. And from reports I've seen on the web it seems to be a known issue where all the mfgs say they can use 32Gb cards but they do not have the software bugs worked out seeing as most people don't own or use them seeing as they are a bit pricey still. At least for a decent one they are
Hey quick question will2live what is the class rating and size on the Wintec card you're using?
I have a kingmax class 10 16 gb card....HC and nookie froyo refuse to boot......well nookie does, but in the next boot, hangs up...
only cm7 runs perfect
hi. thanks truly for reading this.
i was reading through this forum and i was going to buy a SD card (sandisk class 4, everyone seems to agree is best).
people say it doesn't matter what size you buy if i'm just going to stick with one rom like cm7.
what i am confused is people also say that an advantage to rooting vs putting it on my sd card is seomthing about APPS downloading.
i'm confused, can i not use apps or download a lot of apps if i use an SD card? if i buy a big sd card (16gb), shouldn't i have a lot of space?
last question. is the sd card people are buying the sandisk ultra series like the one below?
http://www.amazon.com/SanDisk-Ultra...7HQK/ref=sr_1_2?ie=UTF8&qid=1308541691&sr=8-2
I just did this the other day and had a million questions (that people helped me with), so I can definitely give you an amateur's perspective (although I did a lot of reading here beforehand).
Yes, it seems SanDisk is the card to use, and not too high a class. This is the one I used: http://www.amazon.com/gp/product/B001B1AR50
and it works great.
I put the CM7 on the card because I want to be able to revert the Nook to the original system without a lot of fuss. And I also didn't want to risk screwing things up. I have never rooted my phones, but when I saw this using the sd card, I was all over it.
It is my understanding if you install to the sd card, it occupies it entirely and you don't have it available for extra storage. I'm sure someone will come around and correct me if I'm wrong. I don't know if you could partition it, but that's over my level. So rooting the device would give you more room on a card for apps and media if you need it. But you can still install tons of apps directly on the NC. I think people who actually install movies would run out of space pretty quick, but other than that, not so much.
I followed verygreen's directions very carefully (and still had questions), and things worked out really great. I think the NC with mods is totally unbeatable. And these people here who do all the work so we can enjoy it are amazing.
I used a combination of these links for the process yesterday:

Maybe it depends on what ROM you are using but from my experience you should still have room left on the MicroSD afterward for installing apps. I used Racks11479 Phiremod/Honeycomb dualboot image for mine and still have over 4 GB left on my SD card partition using an 8 GB Sandisk MicroSD. The instructions I used are located here:
http://forum.xda-developers.com/showthread.php?t=1045018
When you burn an OS to a card, you are actually burning the OS to one partition of many on that physical card.
Typically you'll still have a large partition called 'SDCARD' which acts like an SD card, but is still on the same physical card.
So moving files from 'phone' to 'SDCARD' just changes if they are in the 'apps' parition or the 'SDCARD' partition -- they're still on the same physical device.
The emmc (internal) memory is not accessible when running a ROM from the SDCARD (unless you do something to change that fact).
thank you very much for the replies.
just to confirm, are the sandisk ULTRA cards the one people are buying to use with it?
My Class 4 Sandisk 16gb did not say Ultra though it is probably fine regardless since the consensu is Sandisk seems to be a reliable maker.
CM 7 on the uSD makes four partitions. 1st partition is called boot. 2nd and 3rd partition are not accessible. 4th partition is the largest, and is for storage of Apps, music, videos, etcl. On a 16gb card, you have about 13gbs in that 4th partition so it should be plenty for loading up stuff.
