Hi there MacRumors Community! First of all, I'm relatively new to the Mac world - only been a couple months since I own a MacBook Pro - so I'm sorry if this seems like a dumb question. Now, my problem is this simple: I have a pendrive I protected against virus threats following instructions that can be widely found on the web. Among these instructions is to switch the pendrive's file system to NTFS, which, to my surprise, is not fully supported in the Mac environment. I can read files, but not write them... At least not without paying for a 3rd part application to do it for me... If I reformat the disk to FAT32 it'll work on both Mac and Windows, but it'll also make my disk vulnerable to Windows viruses - which would be a problem to my home desktops... Is there a Mac version for protecting a pendrive in the Windows world? Thanks for your thoughts P.S. I'm currently using Mountain Lion on my MacBook Pro and Windows XP and 7 in my home desktops.
