There's no need to wait - you can check that the drive is formatted correctly right now, and save yourself the future hassle and doubt.
Stick a copy of the EvoX dash somewhere on your console (anywhere will do, you don't actually have to set it up as your primary dash) and run that. You'll get a display of your disk free space in bytes.
Stick a small file (less then 1kb) on the relevant partitions and note the difference in free space. Divide this figure by 1024, and you have the cluster size in kilobytes.
Partitions under 256gb should use 16kb clusters.
Between 256gb and 512gb is 32kb clusters.
512gb to 1tb is 64kb clusters, and you can't partition anything larger then that because 128kb clusters don't work.
If you have a mismatch, check your BIOS, backup the drive contents, re-format and repeat the check.
I hear some versions of the X3 BIOS don't support XBP's custom partitioning scheme (which is required for this sort of thing in addition to LBA48 support), but to my understanding the "latest" one in that line should work.
X2 4983 is worthy of note because it doesn't (though 4981 does).
