Micro SD Card Problems

there are multiple posts on here about the card being bad or the reader being bad. I know if I have a 32 Sandisk Ultra and it starts having mount/unmount issues and then it fails to be recognized on my phone or macbook, then it is most likely the card. If I then put a 16gb card into the same phone and same computer that I just attempted to use the 32 gb card on, and the 16 gb card works, then it isn't the phone or phone reader or computer or computer reader.

Some of these 32 gb Sandisk Ultra cards are pure s h it ...no other way to put it. I am using one right now, again, after having my 32gb crap out on me. So far, so could with a few ROM flashes as well. I am not sure if they are designed for crap or I got a decent card on my second try. If I ever have another problem with my 32 gb Sandisk Ultra then I will switch brands for sure.

as I have posted before. I think there may be an aspect of stray electronic voltage from electrostatic discharge happening when handling the card. It is such a small card that it is almost impossible to avoid touching the contacts. The larger sd card is much easier to handle and avoid this issue.. I am very careful now with my handling procedures.

Thats the route I went with after 4 cards from SanDisk that all failed! This card works great no regrets

I've had issues with SanDisk, Kingston, PNY, all of them. Never tried a Samsung.

Used to get corrupted data all the time on my HTC TouchPro2 and P4000 but they had issues with the USB connector so I thought it was related to the phone constantly switching in and out of card reader mode when connected to a PC (usually just for charging).

Recently I went on a trip to the Yukon and ran a dashcam in the form of a Drift HD170 Stealth and one day it turned up corrupted and lost all my video for the whole day. Luckily I was able to recover it with some software.

Just the other day I was using my Note2 and decided to check some files I had on my 16GB SD card that was about 12GB full. Nothing on the card. Tried to recover it and found a few large files (mostly movies and a couple of PSX ISOs) but all the photos I had on it were gone. Luckily they were just a few of my favorite Draw Something sketches I had saved (most of which I had put on FB so it's even less of a big deal) and I had left most of my other photos on the phone itself so that's ok but I definitely could have lost a lot more, especially if I wasn't so used to having to recover data from things.

Was worried I lost all my progress in Chrono Trigger that I was playing through on the phone but the save files are stored on the internal memory so I'm ok since the ISO recovered.

Maybe I'll try a Samsung brand card next.

Just had a problem with my wife's S4 and a Wintec 32gb class 10. I just had it replaced and will see if it fails.

We already have a thread on this...A lot of people are having the same issues
