would be good if Easeus did not cripple their ext* support by binding itself to obsolete x86 linux and its crippled e2fsprogs. Partition Magic 8 does handle larger ext2 block sizes but is not compatible with modern windows. The ext* spec easily allows upto 64Kbyte block sizes and many embeded systems do use the larger block sizes to reduce the tendancy for files to fragment and reduce the DMA/interupt overheads by reading and writing bigger chunks at a time. One shortfall of easeus partion master ext2/3 handling is it only recognises a small subset of the ext* specification and marks partitions intended for ia64 arcitecture or embedded linux NAS/PVR's etc that use block sizes greater than x86 linux ext* 4kbyte limit due to linux inability to work around the 4k page memory mapping it does that only x86 linux has problems with.
