Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Im a network guy, and know very little about system administration. I would like to install PFSense and Monowall to 2 CF Cards, but not sure how they should be formatted (NTFS or FAT32) and volume size. Both of the cards are 8 gigs. I was also wondering if it would be a problem using physdiskwrite with -u flag for disks over 2 gig.

PFSense and Monowall are both based on FreeBSD (which is not Windows, not a Microsoft product, nothing like the aforementioned, does not use their file systems) and use UFS/FFS as their primary file system.

You should let their installers slice and format the "disks". The physdiskwrite utility can write an image file to the cards, you have to override the safety mechanism with -u as Chop has mentioned.

I suspect the correct answer is neither. You should probably follow the instructions for installing an embedded pfsence ( I assume the CF cards will go into some sort of headless box.)

You have to use the -u option for disks over 2GB.

Both use neither. When you write the CF it blows away whatever partitions you have on it. One note, with Windows Vista and 7 and physdiskwrite, you cannot have any partition on the CF that's readable by Windows or physdiskwrite fails.
