  • SATA external HD

    My backups were taking too long, so I bought an SATA to eSATA external host bracket and installed it in my server. I knew nothing about this so I thought I could just boot up and it would recognize my external HDD that I hooked up to it but that did not work. After some tooling around, I found that the BIOS has both "SATA Port A" and "SATA Port B" OFF. I set them to "automatic" I believe, and rebooted but each time I reboot, it gets set back to the OFF setting. Any idea what is going on? Do I need to do anything with drivers or anything? I'm very wet behind the ear with all this.

    What sort? Does it plug into a PCI/PCI express channell or you plug a Sata cable into one of the spare Sata channels on the motherboard & plug the cable into your bracket?

    I ran into a similar problem & bought a PCI SATA/ESATA card

    Then bought an external ESATA enclosure to run D2D backups.

    This got around the problem as it comes with its own drivers.

      It plugs into SATA Port A and B on the motherboard and then installs in a bracket for eSATA access from the outside. That product you listed seems promising though. I don't lose speed by going that route, do I?

        Yes, i suppose you do depending on what speed your SATA channels are on your motherboard. 1.5, 3 or 6Gb channels.

        Wheras the PCI card does a max of 1.5GBps which is still damn fast, but if your doing a few TB this could be an issue. The client I have this on only has about 500Gb in total so the D2D backup only takes an hour or 2. The base that is. The incrementals take a few minutes.

        You might want to plug a spare SATA drive into the channelon your motherboard you intend to use for your esata card & make sure that it all works ok. Try to remove the card out of the picture for the time being while you isolatethe issue.

          I found pci-E sata II cards that transfter up to 3.0 Gbits/S. I purchased one for $40.00. I will post back with results.

            Damn, I bought mine about 6 months ago. I suppose in another few months there will be 6Gig cards. Thats the way it goes in IT I guess.

              Well, I installed the PCI express to eSATA card, and my backup is on hour 22 and still not done. I find that odd. How could it be just as slow or almost as slow as usb 2.0?

                  How many GB/TB are we talking about here?

                  If you plug the drive directly into a spare SATA channel on the Motherboard, does it take just as long? Just for tests purposes, say transfering 1GB ? Then plug the drive into the esata channel & transfer the same 1Gb file & check the time difference.

                    Just as a minor add to this, make sure your disks are defragmented as well as this can seriously affect backup speeds.

                      It is roughly a 400GB backup. How long should that take roughly? Not 24 hours, right?
