Hi, I have an external HDD which has been converted from FAT32 into NTFS. The trouble is that the resulting cluster size is 512B whereas the recommended value for its size is 4 kB, 8x more. Paragon Partition Manager Pro 11 is able to perform a conversion, but I have no idea on how long it might take, for a rather slow 40GB HDD. Is the time proportional to the data there, or to the disk size ? Has someone already performed such a conversion ? Thanks for sharing your experience !
