Numerous complaints are being reported from customers who own the 1.5TB Seagate Barracuda 7200.11 hard drive at the Seagate's online support forum.

The hard drive seems to just freeze during data transfers. Kabatek, Brown and Kellner LLP, a consumer law firm, is considering a lawsuit against Seagate because of the high failure rates of the Barracuda 7100.11.

Seagate, the world's largest Hard drive maker released the 3.5-inch internal drive, Barracuda 7200.11 in July 2008. The hard drive offers 1.5TB of capacity on four platters and uses a SATA 3GB/sec interface, delivering a sustained data rate of up to 120MB/sec. The drive is also available in 1TB, 750GB, 640GB, 500GB, 320GB and 160GB capacities, with 32MB and 16MB Cache buffer size.

Seagate has stated that some other hard drive models like DiamondMax 22, Barracuda ES.2 SATA, SV35 are also affected by a firmware bug which makes the drive fail when the host system is powered on and the data becomes inaccessible.

Seagate is currently offering a free firmware upgrade for the affected drives. Customers can expedite assistance by calling Seagate Support(1-800-SEAGATE) or by sending an e-mail to Seagate. The e-mail should include the disk drive model number, serial number and current firmware revision which can be known by downloading the Seagate Drive Detect software program available in Seagate Knowledge Base.
