[Q] Problem with new SD card.

view story

http://forum.xda-developers.com – So far i have been using the old sd card that came with my Arc S. Its been working fine but ive ran out of memory. So i bought a new 32gb MicroSD HC card. Its class 4. This one to be specific - SanDisk 32GB Micro SD HC Memory Card SDSDQM-032G-B35 I inserted my new sd (empty) into the phone. When the phone started, there was a Sh*t ton of lag. I basically couldnt do anything. You could say the sd card froze my phone. Is this normal ? keep in mind, the sd card was empty. I got scared and immediately removed the SD card. I put in my old sd card, it still lagged but i waited for about 30 m (HowTos)
