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).
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.
I'm buying a nook color as a quick entry into the world of tablets. I plan on using it for reading on the bus etc. But I'm also interested in rooting so I can customize it as well. So I'm planning to dual boot CM7 from the SD card but leave it stock otherwise. With that in mind, what do I need to purchase as a first time Nook buyer interested in modding?
Here's my list:
- Nook Color (of course)
- Aegis Series Enclosure System
- rooCASE (would the nook fit in cases like these with the body armor on?)
- Transcend 8 GB microSDHC Class 6 (read that the class is important when modifying)
- Kingston Flash Memory Reader (to read/write to the SD card)
if your flashing to the emmc class isnt as important, ive been using a plain old class 2 from wallyworld for about a month with no issues.
I have a Sandisk 8GB class 2 form walmart which works fine since I installed the ROM on EMMC.
The speed of the memory card can be a factor with things like video playback, transferring data too and from, etc. Honestly, I would recommend just getting a class 10. The price difference is so nominal that you may as well get something with a little speed. Also, a 16gb isn't much more than an 8gb. So my recommendation...16gb class 10. Something I'm picking up today myself to replace my 8gb class 6 card.
16GB Class 10 for $27.99
16GB Class 6 for $29.99
8GB Class 10 for $19.75
8GB Class 6 for $15.50
I thought about that, but the reviews for larger cards weren't that good so I suck with the 8GB.
The bigger issue is, should I buy it now or wait for B&N announcement later this month?
1) The announcement from B&N about a new Nook on the 24th didn't mention if it was color or not; personally, I'm betting on an update to the original, since the color's only been out for 6 months.
2) Please please *PLEASE* heed my advice on this - if you're planning on running off the μSD card, do NOT buy a class 6 or class 10 card unless you've seen small-block write speed benchmarks. Card Class refers to large-block, sequential R/W speeds, which is good when you're transferring big files on and off of the card, but doesn't factor in quick access or small R/W like you need when you're running an OS from it. I bought a Kingston 8GB class 6 the same day as my NC, 10 days ago, and I almost got to the point of wanting to return the device because of how disappointed I was in it. Then I found this thread -
http://forum.xda-developers.com/showthread.php?t=1005633
and learned about the various card speed tests. I switched to a Sandisk 16GB class 4, and it was like a whole new device. I couldn't be happier with it now.
So, yeah, this is seriously important - read through that thread. And if you live near a RadioShack, they're running a 50% off sale on the good Sandisk cards for the rest of the week.

Strongly agree with this. I got the Transcend C6/8Gb, and had a huge amount of problems (forced closes, and erratic launcher behavior) when running cm7 off of the SD that have completely disappeared since switching to the Sandisk C4/8GB on sale at the Shack. Some radioshacks seem to carry the C2 cards, and some the C4 cards. They are the same price, so it might be worth checking out a few stores if there are several in your area.
If you are just using this as a normal SD card and will be running CM7, froyo, nooter, whatever off of the emmc, then the Transcend is perfectly fine.

Also strongly agree about SD cards. I just bought NC, used a PNY 4gb class 4 to boot off CM7 and it worked but not well, just like hoteladriano - forced closes, erratic behavoir. Will try again with the recommended Sandisks.
I've been using a Patriot 8GB class 10 for a month or so without any problems. Must have gotten lucky. Bought mine at Newegg after being told that a lot of the SD cards at Amazon are fakes, for whatever that's worth.
I"m using a 16 gig class 2 with no issues
I'm using a C6 8 GB Transcend. Saw lots of people rave about them. I'm running the Phiremod/Honeycomb dualboot and see pretty good success with it. Certain apps don't work right and cause force closes (Android Comic Viewer, Pulse) and once those crash I need to reboot to get everything work again. Other than that, its worked fine for me.
That being said, I would agree with everyone here that the Sandisk is your best bet. I may run out to radioshack tomorrow to grab myself another card, just to see how improved my experience would be!

After reading what you suggested and hearing from others I think I'll take your advice. Question is, is it the lower the class the better the performance when running an OS? I'm look at a SanDisk 16 GB Class 2. What do you think?
If I recall, from everything I've read a class 2 Sandisk should be okay, but a class 4 Sandisk would be ideal. If you try radioshack, look through the cards to find a class 4 one. They're not very careful, so they mix the class 2 and class 4 together.

This.
I have a 16gb Sansisk uSD class 2 and everything is good. No FC with apps installed on uSD. I don't store movies on it because I can stream it with CifsManagers and MoboPlayer. I recommend 16gb over 8gb. A lot of games required extra downloads which can range up to 100MB+. Backups can take up space as well.

That ends up really generally being true, because the small-block write speed is precisely what's sacrificed to get better large-block speed, but things can vary so much that I'd stick with either something that's been tested or something from a store with a good return policy.
Without extra details or benchmarks, I would buy a class 2 before I bought a 6 or 10.

I'll love to hear your experience with the new card once you test it.
Yeah, this thread schooled me. I bought a Patriot class 10 card 16gb and OMFG the speed was dismal. It's going back and I think I'm going to order a cheaper Sandisk class 2 for close to half the cost.

Read the linked thread and you'll learn all you need to know. It's the small-block random writes that are important for running an OS, and while it's generally poor in higher-class cards, it varies considerably between models at the class 2/4 level. Also, be sure you're not buying from Joe Blow in Beijing--there are a lot of counterfeit cards out there.

I have the Aegis case for Nook Color, and it's awesome. I've never taken mine off as you have access to all ports including the SD slot, and I've heard that repeatedly taking it off and putting it on again stretches it out and results in a poorer fit. Unfortunately, I bought an Aalto case from B&N thinking it would fit with the Aegis still on, and it doesn't. I don't know about the rooCases, but I've been told that the Rocketfish "Case for Most eReaders" will fit the NC inside the Aegis case, and have ordered one from ebay for $6.99 after shipping.
It's been well covered in general, and you should read the SD card thread everyone's mentioning, but in particular, if you're booting from SD, buy a SanDisk card with a good general rep for fast random small-block writes, then benchmark it yourself with CrystalDiskMark before using it.
My Korean Motoroli seems to be having big problems with the SDcard recently. Originally I had the factory-issued no-name 8gig class 4 in it and now I have some other no-name brand 16gig class 8 in it, but the problems still remain.
The phone will either "loose" many photos when I use the camera (not writing them to the card) or will even sometimes go to a black screen and then just reboot. Sometimes it even just simply hard-locks the phone requiring me to pull the battery.
What recommended bands/class of sdcard would fix this? Or is the problem something else?

Can I ask which ROM you are using? What sort of modifications youve done to the phone? I myself use the stock class 2 8GB and have never had many problems. Since you have the problem on multiple SDcards, it seems like a hardware problem. Bit if you are using a customROM, maybe somethings messing up there. More information would be helpful.

Hopefully It might fix some of my problems...
Well, I got the new SDcard (see above) and it seems to be a little better (slightly more responsive)... but the phone still locks up and and/or reboots when I take a photo sometimes. The chance of it happening seems to be less now, but it's still likely to happen.
Any other ideas? Have any other users had a similar problem to this?

Card type and class has much to do with camera quality and also video too.
Surprised there isn't more talk about this issue with all the sdcard issues we have. With HD recording and an 8mpxl camera it seems we need a better class card, I need to get a couple for my phones and I am trying to find the best buy on a samsung. My question for anyone who has experience is if I spend the money on a class 10 samsung, is it going to make a big noticeable difference? Will it stop a lot of the issues or is the issue more related to Android and even more so with XT720? Is there anyone who has upgraded who can answer? Seems it will but I would hate to spend the money and not get much improvement.

I am currently using a Samsung Class 10 16GB card that I ordered somewhere online. My main Issue always was with transferring media and this card tackles the problem with ease, I do not get black screen problems anymore. The camera seemed ok with no major differences that I noticed, but usual camera freezes have reduced. Overall I would suggest an upgrade.

Hi maruki, does it fix your sd card problem. I am also experiencing sd card problem when taking photographs or any activity that will require writing to sd card. (Downloading, etc) I am also suspecting it is a sd card issue and hoping the problem is not on our device. I also plan to buy new one since I am using the stock mem card that comes with the unit. I want to know if it worked for you.
by the way, setting the camera to lower resolution seems to fix the sd card writing failure in my case.
there is new type of sd card, UHS-1 which seem to to deliver a very high speed and write, topping any current sd card in market now as decribed here: http://www.engadget.com/2012/04/05/samsung-ultra-high-speed-microsd/
maybe when it's available I'll purchased one, also the best thing is that it can be used for swap ram to fix xt720 low ram problem. do you think so?
but I'm also not sure if these uhs-1 cards are compatible with xt 720 or not. If anyone plans to buy one when it's available please review after that i'll also do a review when I get one.
class 10
buy a class 10 memory card
I recently bought a Patriot 16GB Micro SDHC LX Class 10 card for my I9000 Galaxy S. The one problem I have had is that it does not recognize my card at all. I have done everything from FAT32 formatting to formatting as FAT32 without LBA. However, I do not believe that the microSD itself is faulty. My old Nokia E63 can read and write to this microSDHC perfectly well, even though the E63 officially only supports cards up to 8 GB. Windows can also read and write to the microSDHC card perfectly. Is there any known issues with Galaxy S and Class 10 cards? I thought Galaxy S can support any microSD card up to 32 GB. I have contacted Patriot to return the card but I'd rather get it working if possible. I am currently using an old 8 GB class 4 kingston microsdhc on the galaxy S and it works well. So, it seems that there is some incompatibility between the Galaxy S and specifically the Class 10 Patriot because they both work well independently.
1. Does anyone know why this happens?
2. I am now looking for another good microSD card, with at least 16GB. Is there any that is recommended and definitely known to work with Galaxy S?

Just a comment about Patriot Warranty be very patient it took me 2 months and lots of *****ing to get a replacement
I don't think so. I have the same Patriot SDHC 10 class 16GB on my Galaxy SCL (i9003) and they work perfectly fine with each other, apart from 3 damaged images from the gallery so far. Anyway, they it does recognise the card.

You might be right, I filed a request last week and I am still waiting for them to contact me. Sad, because my Patriot USB Drive works great. Bad Customer service from Patriot.
I was initially wondering if it had something to do with the ROM I am using. I tried the card using Cyanogen 7.1.0-RC1 and now with Darky's EE 10.2 JVQ, but no luck. Plus, it doesn't make sense that the ROM would have something to do with this.
