HDD firmware update …

At the review date, the company Seagate provided the firmware version SN02 for the constellation has. 2 hard drives, which has been updated before the test. The update of Seagate firmware can be done quite simply, because the firmware download is an ISO file with a tool for creating an USB boot stick. However, when you get an “undefined video mode number: 310” error message during upgrade, confirm it with space, then select firmware download (!?!) and then automatically starts the update for all possible drives. In the current review, we have updated the latest firmware SN02 to the drive, which was delivered with the firmware SN01.
