DOS ain't dead

YSDDT 0.1.2 (DOS Toolkit for Working with Disks & Partitions) (Announce)

I tried the fata (align) option and it seems to work as expected. It created reserved sectors before FATs to align data start and it moved the existing data partition without loss.

BTW how important is CHS values matching to LBA values in the partition table? Is there some tool that automatically recalc CHS from LBA values in partition table? And what CHS values should be set for partitions beyond 8,4GB? Is there some rule of thumb or it doesn't matter in any way? It seems that tools like Gparted, when set to LBA alignment, it calculates some CHS address that of course then doesn't align to CHS and some old DOS partitioning programs like PQ magic complains. BTW CHS geometry of drives also may vary. My SSD reports 240 heads, 63 sectors per track under DOS while under Linux it's 255 heads and 63 SPT. My mechanical HDD has 255 heads both under DOS and Linux. This also lead me to not care about CHS much. Maybe some old DOS 3.x/4.x may complain but I use at least DOS 6.22 and 7.1.
