We have experienced what seems to us to be an inordinately high number of drive failures on the ES.2 series. Though, in our case the drives die midstream and generally not during a boot of the server.
- 750GB Seagate ES.2 on a RAID 1 array
- 750GB Seagate ES.2 failure on SR1530AH plus SRCSASRB
- Seagate 750GB ES.2 Failure on SR1530AHLX swap experience
- Seagate 750GB ST3750330NS Failure on SRCSASRB
- Firmware Recommendations for Barracuda 7200.11, ES.2 SATA, and DiamondMax 22 Drives 
- Firmware Update for ST3250310NS, ST3500320NS, ST3750330NS, ST31000340NS 
When we have had a dead drive in the past that has spun up with no internal sounds indicating drive heads being flung about within, we have had some success with switching out the daughter cards that contain the electronics.
In this case, we have not had any drive failures related to the firmware situation, so we cannot test to see if this does indeed enable us to gain access to the drive's contents. We have seen some indications that we may not be able to do so.
A small bonus for us is the ability to obtain an RMA from our supplier for one full year after the original purchase and have a replacement drive the following day. The drawback is that we have consistently had the defective drives replaced with identical ones.
