I recently bought a 3 TB external hard drive. 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: <Initio INIC-1615P 0101> 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!
