What is ATA-6 or ATA-7 drive means?I can only find ATA-100,ATA-133,SCSI and SATA harddrives (2.5").What is this ATA-7 or Hitachi have product like this?

ATA-6 is the laptop interface spec for ATA-100, and ATA-7 is ATA-133. An ATA-7 drive will run in ATA-6 mode if the notebook's IDE controller does not support the former. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
