1) I placed the 1tb drive into my #2 system and then booted that system
using a recent vintage (0.18.2) version of the "Gparted Live" CD.
2) I used Gparted to create and initialize a GPT partition table on the
drive.
3) I used Gparted to create and initialize a single partition (containing
all free space on the drive) and had it (Gparted) create an ext3 filesystem
on that partition.
4) I then performed a clean shutdown of Gparted.
5) I then removed the new 1tb drive in question from my #2 desktop system
and moved it into the hot-swap rack of my main (FreeBSD 9.1-RELEASE) system
(which already contains two other drives, i.e. ada0 and ada1).
6) I used the power switch on the rack to power on the drive.
The result of the above operations is as follows:
May 15 21:53:33 segfault kernel: ada2 at ata5 bus 0 scbus5 target 0 lun 0
May 15 21:53:33 segfault kernel: ada2: <Hitachi HTS541010A9E680 JA0OA480> ATA-8
SATA 3.x device
May 15 21:53:33 segfault kernel: ada2: 300.000MB/s transfers (SATA 2.x, UDMA5,
PIO 8192bytes)
May 15 21:53:33 segfault kernel: ada2: 31MB (65134 512 byte sectors: 16H 63S/T

May 15 21:53:33 segfault kernel: ada2: Previously was known as ad10
May 15 21:53:33 segfault kernel: GEOM_PART: integrity check failed (ada2, MBR)
Some Linuxes (Linii?) might be creating "hybrid" GPTs, with a PMBR that
is non-standard. I can't speak to what Gparted does.
There is a sysctl to relax the strict checking in FreeBSD, but I would
suggest using gpart(8) instead. (Backups necessary, etc., and this is
off the top of my head and untested.):
# gpart destroy -F ada2
# gpart create -s gpt ada2
# gpart add -t \!0x83 -b1m -a4k ada2
(That 0x83 is for the Linux partition type. gpart(8) might have a
keyword for that, like "linux" or "linux-data".)
Then newfs /dev/ada2p1 to ext2 or 3.
The steps would be nearly identical for MBR, but avoid MBR if you can.
