Something like "adap1" doesn't exist. It's always "ada<dev>p<part>" for GPT partitioned disks (either using "ada", "da" or "ad" for the disk driver, depending on your configuration). > It is > partitioned with two primary partitions (GPT) GPT does not have primary partitions, MBR has. But you would see that fact reflected in /dev. Example: GPT: /dev/ada1p1 /dev/ada1p1 MBR: /dev/ada1s1 /dev/ada1s2 /dev/ada1s2a (maybe more) You can use "gpart show" to examine what partitioning data is actually present. "fdisk" will also tell you (for MBR only). This is usually easier than concluding from the device files. > one is ntfs for windows > and I want to create a UFS files system on the other but it doesn't show > any partitions. So there is _one_ partition, plus unallocated space? Or is there already a second partition which you want to "re-use"? As mentioned, use "gpart show" to check. If you know the device name, you can simply run the following command: # newfs /dev/ada1p2 in case there is a 2nd GPT partition present and you want to write a UFS file system on that. Also read "man newfs" for UFS options you might want to set (like soft updates, journaling, optimization and the like). Before you do so, make _sure_ that you're operating on the _right_ partition! -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
