It is not just the ssd, the pc bios had design problems in it's allocation for drive geometry (Cylinders, Heads, Sectors) and the first limit found was that it was unable to represent drives larger than about 500 Megabytes. Drives very quickly(early 90's) started lying about their geometry to get around this limit. There were various schemes of this and it finally ended up with abandoning physical(CHS) addresses entirely and just let the drive figure it out by moving to a flat address model(Logical Block Addressing), note that LBA mode was around long before SSD's http://www.steunebrink.info/bioslim.htm http://www.steunebrink.info/bioslim.htm
