Can't access file system

[wispy zephyr]

Hello everyone.
I have a small problem with drive permissions. I recently installed Windows on a hard drive but now i don't have write permissions on another drive (SSD, fuseblk).
Is there an easy fix for that?

PS: Sorry for any noob problems.

what's the filesystem?
if ntfs are you using ntfs-3g or ntfs3
if the latter have you checked the perms?
