I am wondering what is the difference in the designation listed in the Data Lifeguard Diagnostics where drives that are connected with SATA cable are labeled ‘ATA’ in the list while other SATA drives are labeled ‘SATA’ - what is the difference (why are they labeled/listed differently)?
ATA describes the command set developed back when EIDE class disks were available. This allowed a BIOS to recognize the disk particulars so it was no longer necessary to select a disk from the BIOS table of older machines.
SATA is simply a serial link to the disk as compared to the old parallel cable. The command set is the same however there have been some changes with the disks now growing past 2TB and the introduction of 4096 byte sectors etc.

To clarify: I am not asking the difference between ATA/SATA. I am asking why DLD lists drives differently despite them all being SATA drives - even when they are both WD drives.
try checking the disk with crystal disk reports
