not working for recovery. it can read the card but not write to or install from.
Card disapearing at random - including in recovery and in the OS
Phone rebooting at random during use of the Card.
Running perseus kernel and i tried Exfat of different block sizes and fat32 of different block sizes. in fat32 i cant even access the card in some of my apps which is really weird. like they will see the card and the files but not necessarily be able to access them....

anyone else with similar experiences? and this odd stuff only happens during heavy load on the card. if i dont use it too much my note 2 can go on for days without problems.

Just started having problems the last few days myself. Running a Sandisk 32gb Class 10 that I bought from Amazon back in February. Now I've got a phone that reboots every 5 minutes, my file explorer showing my SDCard as empty, reported size as 10gb, files that I can't delete, and once got a SDCard Damaged error. I formatted it, and it was stable...for about 6 hours. Finally just removed it from the phone and haven't had anymore problems.

I've got the same problem as the guy above though, where I bought it from Amazon, who's return policy expired at the end of March, and Sandisk isnt going to warranty the POS. Gonna have to break the news to the wife and shell out another $30 for a new one...this time from a manufacturer so I can have a warranty. Thanks Amazon.

What 64gb class 10 card do you guys recommend? Thx

I had a Sandisk ultra 32gb that worked great for a month then eventually kept unmounting itself and then data corrupted. I bought a 32gb Samsung class 10 card and haven't had any problems since.

My 64 sandisk is fine. Had it nearly as long as I've had the phone. Since before Christmas. No issues once I learned it had to be fat32 for aosp roms

Sandisk cards are utter/total garbage. Just the amount/quantity of problems reported in this thread alone should convince anybody who was on the fence before about a purchase of this crap.

Unfortunately, I have three of them that I bought when the 64gig cards first came out & the Sandisk brand where all that was available at the time (my employer paid for them or I would REALLY be pissed).

I have now had four Sandisk cards replaced under warranty (same problems as all the other posters where reporting). I still use them, & keep them backed up religiously but I would definitely not buy another one at this point.

Of course in any thread like this, there will always be the occasional poster that claims "I have had my card for years & never had any problem whatever with it, you posters having problems are all idiots". Clearly not every single card is defective but Sandisk has FAR FAR too many defective ones per hundred/whatever compared to any other brand.

Since I am the head of the IT dept where I work, all our defective stuff runs through me & I cringe anytime a user comes to me saying I have 9 gigs of music files on my 64 gig card and the card is saying it is "unreadable" for some reason. If we are on the phone, the first question I ask is "is the card red & gray??" (already knowing that it will be).

I have wasted more time running disc recovery apps for users trying to recover all their bootleg music files when I know right up front it will probably be a complete waste of time.............

I have the 64gb Sandisk card in my n2. So far I have gotten lucky and my card has lasted about 6 months, hopefully my card was "built on a Wednesday" and will continue to work. I was wondering what brand do you recommend? I would like to buy a backup card just in case mine finally gives up the ghost. For now I use an OTG connector and a usb drive to do regular backups of anything I feel valuable.

Fat32, no issues in my N2 or my wife's. We've been running them since the 1st day that we got our N2's on release day. Keeping my fingers crossed.
Also had a Lexar 32gb class 10 in my last phone. It crashed and burned and I lost everything.

I bought a SanDisk 64GB ultra on sale at BB for $59, got it a month ago when I purchased the phone. So far no problems, I have only flashed TW roms.
