The problem might be that drive is 6Gb/s SATA and your box runs a 3Gb/s SATA bus.

You may have to manually jumper down the 6Gb/s to 3Gb/s

Thank you for response. I did go to the Seagate url to find the short block configuration for the STBD1000400 hard drive. Did not work.

I also clone to a Toshiba MQ01ABD100. Same result as the Seagate clone. Did not work. Same unit as listed for sale by
