When it happens, the system freezes for around 30 seconds.

Seagate told me that there is no firmware update for this drive.

Please, let me know if it is a software issue.

Quite unlikely, it looks like something caused the communications with the drive to be dropped. It's likely either a drive, cabling/connection or power problem (the latter two seem unlikely in a laptop though, unless the drive isn't connected all the way or something..)
