Thanks Elimar! Here's what it says:
root@bigal:~# hdparm -I /dev/sda | grep -A15 Configuration:
Configuration:
Logical max current
cylinders 16383 16383
heads 16 16
sectors/track 63 63

CHS current addressable sectors: 16514064
LBA user addressable sectors: 268435455
LBA48 user addressable sectors: 1953525168
Logical Sector size: 512 bytes
Physical Sector size: 4096 bytes
Logical Sector-0 offset: 0 bytes
device size with M = 1024*1024: 953869 MBytes
device size with M = 1000*1000: 1000204 MBytes (1000 GB)
cache/buffer size = unknown
Form Factor: 3.5 inch
The disk itself is one of the new Seagate "hybrid" disks, with 8GB of flash and 1TB of "Advanced Format" spinning iron oxide.
Has anyone tried this with the Wheezy for x86 or amd64? I'm wondering if it's a bug resulting from something having to do with PowerPC, or more general than that...
Thanks!
Rick
