RAID block size limiters

If you are doing a RAID Recovery and the software has the capability to limit the allowed block sizes for search (which is quite often actually, ReclaiMe Pro has it, Runtime has it, ZAR has it, and perhaps R-Studio has too), and if you happen to know the block size exactly, do not set the limiter to exact block size.

If you know the block size is 128 whatever units, set limits to 64 low and 256 high (of the same units, repeat, the same units). Otherwise, if the automatic detection gets you the value at one of the edges of the range, you do not know if it is because the value is correct, or because it hit the limit and was not able to further change the block size. The final block size must be inside the allowed range, not on the edge.
