why does my phone say sd card damaged when i partition it

[suyog001]

I've rooted my phone and installed link2sd from play store. when i partitioned my memory card using mini tool partition, everythg works great but when i insert it into my phone, it says,"damaged sd card. You may have to reformat it." My phone uses gingerbread and my phone is dtc gt5s.

I'm guessing you formatted it in a Windows machine so it has the NTFS file system. It could also be possible that the system can't recognise it because the partitions aren't regular sizes - multiples of 4Gb.
