Posted by Gurpreet Singh on 22 August 2011 03:47 AM

Problem
A number of Seagate hard drives from the following families may become inaccessible when the host system is powered on. Once a drive has become affected the data becomes inaccessible to users but the data is not deleted. Seagate has isolated this issue to a firmware bug affecting drives from these families manufactured through December 2008.

Solution
If your drive is affected, a firmware update is required to resolve this issue. At Iron Systems we use

  • "AS" drives in our A Class, Value Series of iServers product line, wherein maximum drives installed are two.
  • "NS" drive is used in all of the remainder iServer and Storage product lines.

To identify your drive, retrieve the model number, serial number and firmware revision without removing your drive. There are multiple methods, for detailed instruction please follow the below link:

If you have one of these drives please choose it from the list for model-specific instructions to update the firmware.
