I got a new 1.5TB hard drive (Seagate ST31500341AS) for a Windows box. Of course, Windows spends all day trying to format it to NTFS and then after many hours ...

Partition block size
I want to have an NTFS partition on there with as large a block size as possible, as it will only be used to store very large files (in the order of hundreds of megabytes each). The highest block size the Windows disk manager will let me choose is 64k.
GParted can create and format the partition successfully within seconds and it is usable from windows but it gives me no option for block size. Is there any way to customise this, either from the command line (fdisk, etc) or from gparted itself? I am comfortable with command line Linux, just not so comfortable with cylinders, sectors, etc.
In case it is useful, here's the fdisk -l:
Disk /dev/sdb: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x120aa019 Device Boot Start End Blocks Id System /dev/sdb1 1 182401 1465136001 7 HPFS/NTFS

the block size is set when you create the filesystem on the partition, not when you create the partition, you should be able to set the block size in it when you format it, I'm not in front of a windows machine, but you should be able to right click the disk and click format, should be an option specify block size, don't bother with a full format either, quick format is just fine

i'm not sure you can create ntfs fs on linux, the only options I have on my system are vfat and msdos

** Also, are you letting Windows do a full format? This is what takes so long - make sure to select "Perform a quick format" when creating the partition in Windows.
-c, --cluster-size BYTES
Specify the size of clusters in bytes. Valid cluster size values are powers of two, with at least 256, and at most 65536 bytes per cluster. If omitted, mkntfs uses 4096 bytes as the default cluster size.
Note that the default cluster size is set to be at least equal to the sector size as a cluster cannot be smaller than a sector. Also, note that values greater than 4096 have the side effect that compression is disabled on the volume (due to limitations in the NTFS compression algorithm currently in use by Windows).
