Warning, Seagate Barracuda 7200.11, DiamondMax 22, Barracuda ES.2 SATA hard drive owners. Yes, this is a very serious warning coming out from Seagate itself. Because your hard drive might become inaccessible when you power up your PC system. I got an error comment from an anonymous on January 11th, 2009. At first, I thought just an anti-Seagate wondering around and doing some damages to Seagate branding. However, I changed my mind after seeing this announcement.

Oh no… My hard drive is on the list!

SAS (Serial Attached SCSI) is a computer bus technology primarily designed for transfer of data to and from computer data storage devices such as hard drives, CD-ROM… It is a replacement for parallel SCSI. It is also backwards-compatible with SATA drives. It uses serial communication instead of the parallel method but still uses SCSI commands.

SAS (Serial Attached SCSI) vs parallel SCSI

• The SAS bus is point-to-point while the SCSI bus is multidrop.
• SAS has no termination issues and does not require terminator packs like parallel SCSI.
• SAS supports a higher transfer speed (1.5, 3.0 or 6.0 Gbit/s).
• SAS can supports up to 16,384 devices.
