microSD Transcend trouble?

[MaxBeg]

In my ZF2 (ZE550ML) I use microSD memory card by Transcend (like microSDHC Class 10 (Premium)).
Some time in notification area i see notify about what is my micro SD card inserted, but I don't remove it before.

Why is this happening?

I notice this from time to time as well. Not sure if the card is inadvertently unmounting briefly, then mounting again. I hardly use my microSD card, so I haven't been able to tell if it's causing any file corruption.

I believe I get this each time I restart the phone and every update. Doesn't seem to cause any problems so I've ignored it but am curious as well. I don't use the same brand card as you however.
