[Android Software Development] nodiaque:
Hello,

I'm having a hard time with my sdcard.

I've did some partition alignment per a guide and everything was fine. I then did some testing as of what type of partition I want for my data2sd, tested many thing. Then, I had a problem: couldn't restore backup anymore, recovery says folder not found. I mount the sdcard in my computer and check, everything is there. Unsure, I put it back in my phone (desire), boot back in recovery, mount sdcard in adb and do a ls.

Very ugly what's showing:

I've tried formatting the partition, repartition the whole sdcard, change the head/sector count to stock, doesn't change anything.

What's funny is that only those two are having a hard time reading from it. I can mount it into windows or read from android without any prob.

Is my brand new sd already dead?

Thanks
