As shown in several forums, this card works just fine, on many phones officially limited to the 32GB microSDHC. In particular, HTC Desire Z. However, it is necessary to format the card correctly under penalty of strange behavior: the phone will reboot itself at times (start, return the USB mass storage mode). The Android system will indeed format the card first, but by doing it for myself too FAT32 allocated clusters. The fsck_msdos verification tool allocates memory from what number of clusters, and in my case, the file system check required to allocate 60MB. Too for Android that decides to kill everyone. The parade is to change the number of sectors per cluster (I put 64) and the number of clusters decreases FAT32 (from 15,561,282 to 1,948,483 in my case). Thus, the file system check will require more but 7MB to 60MB and everything works better.
