I attached it to the Firewire (400) bus and waited for my 8.2-STABLE i386 system to recognize it. After a small flurry of Firewire protocol messages, the kernel eventually said, Feb 12 23:35:42 hellas kernel: da2 at sbp0 bus 0 scbus0 target 1 lun 0 Feb 12 23:35:42 hellas kernel: da2: Fixed Direct Access SCSI-0 device Feb 12 23:35:42 hellas kernel: da2: 50.000MB/s transfers Feb 12 23:35:42 hellas kernel: da2: 2861588MB (5860533167 512 byte sectors: 255H 63S/T 364801C) So far, so good, I thought. Next I tried to use gpart(8) to set up a partition table. However, gpart, gpte (from sysutils/gpte), diskinfo(8), et al. only see the device as a 2 TB drive. hellas# diskinfo -v /dev/da2 /dev/da2 512 # sectorsize 2199023253504 # mediasize in bytes (2T) 4294967292 # mediasize in sectors 0 # stripesize 0 # stripeoffset 267349 # Cylinders according to firmware. 255 # Heads according to firmware. 63 # Sectors according to firmware. # Disk ident. hellas# I have searched the archives of this list and several others, but haven't found anything helpful. This disk is *not* intended as a boot disk, just data storage. Is there any hope of using its full capacity? Or have I effectively bought an overpriced 2 TB drive? Please Cc: me directly in any replies because I am subscribed to the digest form of this list and would like to see responses without having to wait up to 24 hours. :-) Thanks in advance for any help!
