Cannot boot after change cluster size of data partition

Hello,
I was using the Acronis Disk Director 11 home to change the cluster size of my Data (D:) drive from 4KB to 64KB, after finish, my system cannot booted anymore, my system is on C: drive and I did not changed it cluster size (still keep the 4KB as default).

My system is Windows Server 2003 Std. Edt. The C: and D: drive is on one HDD that is install on ID3 of the Adaptec Raid card.

but the system can be booted by using the hiren's bootCD with the option "Boot From Hard Drive (Windows Vista/7/2008 or Xp)".

So can anybody help me to fix this error, so my system can boot back as normal (booted from system drive without hiren's bootcd).

Can I using the fdisk /fixmbr to fix this problem ??

    hello,
    My boot info is on the c: drive
  3. Have you tried resizing the clusters on D: drive to their original size? My guess is that the system has a hiccup with trying to arbitrate two different HDDs with different cluster sizes.

    I know that this is not something you want to do, but if it works you then know what your problem is. You can always resize the clusters again if this proves false.

    Just for curiosity, why did you change your cluster size up to 64 KB?
