1. you install linux in /dev/hda and using LVM and its mounting well 2. you want to mount /dev/hdb to linux is that correct? if its correct, my question is : 1. is your /dev/hdb formatted / partitioned? even if its partitioned under windows, dos or other OS its still counted as partitioned. 2. if its partitioned and FORMATTED with some filesystem (eg. if you partitioned the drive under windows you should formatted the driver under NTFS of fat32, if its under dos then it should be fat.), then you need to find out the RIGHT filesystem format that you format the drive with. 3. when you find out the right filesystem format (eg. ntfs / fat) then you can mount it using command mount -t vfat /dev/hdb /mnt or mount -t ntfs /dev/hdb /mnt . or edit your /etc/fstab to make it automount everytime you boot your system. note: for ntfs you will need to recompile the kernel for ntfs support (use modprobe -l | grep ntfs to check if you have the ntfs module or not) or get ntfs-3g driver or captive ntfs for read and write support. 4. but seeing your fdisk -l result I dont think that you have partitioned and formatted your /dev/hdb yet. One easy way to check is to boot to windows and see if you can access /dev/hdb or not. if you havent partitioned and formatted the drive yet the you should do so before mounting it.
