Package: util-linux Version: 2.20.1-4
Hi!
On my system (a simple PC, i686, not amd64), I observe a strange
behaviour with a newly bought 3TB USB drive:
Kernel's size impression:
[1923904.014512] sd 4:0:0:0: [sdd] 732566646 4096-byte logical blocks: (3.00
TB/2.72 TiB)
[1923904.019507] sd 4:0:0:0: [sdd] Assuming drive cache: write through
cfdisk:
Disk Drive: /dev/sdd
Size: 3000592982016 bytes, 3000.5 GB
Heads: 255 Sectors per Track: 63 Cylinders: 364801
Starting with an empty partition table, I intended to create four
primary partitions of roughly 750GB each. For the first three, I
choosed "New", "Primary", "750000", "Beginning". The last partition
was set up using the suggested size (using the complete rest of the
hard drive.) After "Write"ing the partition table, the kernel isn't
happy with the partition table:

Creating a PT with plain `fdisk' works well, using four primary
partitions with (first three) 730000000K and all defaults for the
fourth partition:
