Since switching from a SanDisk 8Gb class 2 MicroSDHC to a Kingston 16Gb class 10 MicroSDHC (manfacturer part number SDC10/16GB-2ADP) I keep getting problems starting up apps that use the storage slot. For example, when I start CoPilot Live 8, it just freezes and I have to power off the phone, pull out the card, re-insert it and power on again (if I don't re-insert the card then a phone reset doesn't allow me to use the card right away).
Is the TP2 ok with this card, or is the card defective? I don't have problems using it with a USB MicroSDHC adapter.
I might save this card for use with a newer phone, perhaps a HTC Desire or Legend.
I don't know the Kingston, but my Sandisk 16 GB does not make any problems.
I have the SanDisk 16gb and have had no problems at all. Have you formatted your Kingston sd card? Maybe try formatting it on a different computer, or by putting it into a digital camera and using its format function? Hope that helps...

Yes, I've tried formatting the card. It made no difference.
I guess my question comes down to what class card the TP2 supports. I understand that the cards themselves are supposed to be downward compatible with devices that don't support the higher speeds, but some devices might struggle. I don't know what card class is supported by the TP2 (2,4,6 etc). I imagine any class 2 card would be fine, but what is the maximum class the TP2 should be able to support?
I don't believe it's the card because I'm experiencing the same problem. I initially started using the card in a nokia e71. bought the same reader as you: it just freezes and I have to power off the phone, pull out the card, re-insert it and power on again (if I don't re-insert the card then a phone reset doesn't allow me to use the card right away).
I'm using some noname 16gb card I got off eBay. Used it in my Incite and now in my Tilt 2 without issue.
Download trial of Pocket Mechanic Pro and run disk check and for errors. Missing not having two copies of FAT directory onboard causes many problems. Pocket Mechanic Pro is one WM tool really worth having.
I dunno if I've just had a run of bad luck with external SD cards, but in two months I've lost 2 SD cards! One 32G Sandisk, and just today another Lexar 8G (cuz I couldn't afford another 32G).
But it just frys them to the point where they just don't read anymore. I even try putting them in a card reader in my PC, and no dice. All my pics, music files, nandroids gone. Stuff that I unfortunately didn't back up on my pc. (Kicking myself hard)
My question is, has anybody else been losing SD cards? And, is there a program or a method that could possibly salvage any of the files on them despite them not being read by any card reader?
Any help much appreciated. Thx

I had a 32GB Sandisk microSDHC class 10 konk out less than a month and chucked it to a bad card. Sandisk replaced it. Prior to that I had a 16 GB in it for months and those were fine.
I think in your case it's just the cards going bad. I think the Sandisk 32 GB microSDHC might just have a bad batch somewhere. I got it from Amazon.com.
Yeah I think you have a bad card also
I use a 32 gig class 10 on my evo shift and the S3 shoots it out of the water, and I've never had any problems with the sdcard on my shift
I thought about switching the internal SD card with my external Sandisk 32 GB Ultra Class 10 UHS-1 SD card to increase the amount of usable storage for apps. I used SD Card Tester app to test the speed of both internal and external SD cards. Write/Read speeds for the internal/external cards were 34.1/38.8 MB/s and 7.8/15.2 MB/s respectively. Are these results basically correct? Would switching the internal to external SD result in much of a performance loss? Are there any external SD cards within similar cost to this Sandisk that have better Write/Read speeds?
As far as I know, we do not have a UHS-I capable slot, and without Apps2SD I've never benched what it can do.
Past that..... Your own math likely has your answer.

I have 64GB Samsung Pro SD card that the phone won't read. My computer reads it just fine but the phone won't. I've tried formatting it, reseating, and cleaning the contacts. Does anyone have any other ideas what could be causing it not to read?

I'm not sure I tried all three of my cards 64gb evo and two 128gb sandisk cards. Have you tried formatting it by another device perhaps?
I tried setting as internal storage a low cost class 4 microSD ans it was accepted on my HTC, though apps were lagging a lot. Today I bought a 64Gb UHS U1 card which is considered to be at least class 10 speed. And my Marshmallow says it's too slow! Wtf? Is there any trick to pass this check or any root app that would do this job?
Reformat the card in your computer and try again. I have a SanDisk microSDXC UHS-1 Class 10. I got the same message the first time.
