I thought about the pros and cons of buying a HDD that I didn't know was compatable.
The pro's out-wayed the cons so i bought a 'Seagate 6.00Gb/s, sata3.0, 2TB, 64Mb Buffer, HDD'.
(I Figured at worst; I'll still have a 'sata3.0, 6.00Gb/s, 2TB HDD' .I can keep it until I build a brand new PC.)
It had no jumpers. It was an auto.
The device would not install or show anywhere...... It kept making a scratching sound and sounded damaged.
I still had the old O/S on a working HDD, so I downloaded a program from the Official Seagate Website,
It found the HDD so I could partition and format the 2TB HDD, I think the file was about 150MB in size.
The program was fantastic.
After the HDD was found, partitioned & formated by the manufacturers software, it made no strange sounds.
I now have a 2TB slave full of mp3z, Digital Videos, & .pdf's. Not to mention I have backed up Iso's of all of my expensive software, incase of theft or damage to discs. It was really worth the risk.
I must admit, I only have an old "IBM p4 3.0ghz HT, 2GB Ram, 256MB Video Card", so this tells me that "ALL SATA DRIVES (1+2+3) ARE BACKWARDS COMPATIBLE WITH ALL SATA PORTS (1+2+3)", One Way Or Another!
