That's just a default value reported by the PCB when the drive fails to initialize properly. How does the drive sound when it is first powered on? Does it click at all? Does it keep spinning or does it spin down after a few seconds?
Given that it's a Grenada family drive, with that symptom, it's most likely failed read/write heads.
Hi My seagate 500 GB barracuda in clicking after powered on an after a minute it stop spinning What should I do!?
If it stops spinning, there is little you can do without professional tools and facilities. At the very least, determine the value of your data and be 100% certain that your data is not worth the cost of professional services before you attempt anything more.
