Vista Install Help: Need to Change Cluster Size on Format

So I'm installing Vista for a media PC and I need to force it to format the drive in NTFS to a block size of 64kb instead of the default which is 512b. This keeps the recordings smooth when I'm recording TV.

Anyone have any ideas?

Thanks!
 
Ouch! 512 bytes? Was the drive converted from FAT32?

If you're talking about installing Vista onto a boot / system drive (or partition) with 64 kilobyte allocation units, then I guess you might boot with a pre-install environment disc and use the format command. I don't think installing the OS onto such a partition would have any advantages at all, though.

But if you're talking about a separate data drive or partition, then just install Vista first, then use the format command from the CLI to format the target partition.

If you type

format /?

at the command line interface you'll get a summary of the switches and options that work with the command. The switch which controls file system is /FS, and the one which controls the file allocation unit size is /A.
