NTFS cluster count too high after raid expansion

[Velocityraptor]

Hi folks,

after migrating my 9x2 TB RAID 5 Array to 10x 2TB (3ware 9650SE 16ML Controller) the additional disk space remains unavailable because the highest allowed number of Clusters is exceeded (Windows 7 64 bit, NTFS with Default Cluster size 4K)

Acronis Disk Director wasn´t able to fix this on the fly by changing the cluster size to 8K or 16K because the partition type is "invalid".

in fact I have a dynamic volume with a healthy 18TB partition and an unassigned 2TB volume now (according to Windows storage manager).

any idea how this can be fixed without creating a completely new RAID volume (which means backing up and restoring all data from the old volume) ????

Thanks a billion in advance for your help !!

Too many clusters? Crummy driver.
