Your reply gave me a clue. I did a search for sata in the docs and found this for both drives I linked to in other post. Exos X18 SATA drives incorporate connectors which enable users to hot plug these drives in accordance with the Serial ATA Revision 3.3 specification. I suspect that means it has the PWDIS pin. You agree? If you open the links to pdf docs in other reply, search for "Hot-Plug compatibility" and see what it says. It was the second hit for me. Why can't they label those drives with something that makes it clear. Print 'SATA V3.3', 'hardware reset enabled' or something that makes it easy instead of sticking it in a 50 something page document. At least we have the "find" feature on most pdf viewers. Another option, throw a adapter in the box for those who can't have that feature. Looks like both drives I'm looking at might not work for me. My goal in this thread, figure out what to look for so that I avoid buying a drive that don't work. I got the difference in the power cable at least. Now to figure it out without being able to see the drive. Thoughts? Dale :-) :-)
