Welcome, Seagate hard drive owners. A number of Seagate hard drives from the following families may become inaccessible when the host system is powered on:
Barracuda 7200.11
DiamondMax 22
Barracuda ES.2 SATA
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.
Please use the following tools and instructions to determine if you have one of the affected products. If your drive is affected, we recommend that you update the firmware on the disk drive to prevent this condition.
To identify your drive, retrieve the model number, serial number and firmware revision without removing your drive. There are multiple methods:
Seagate DriveDetect.exe method (recommended)
Click here to download Drive Detect:
When running Drive Detect you will see a screen like this. Look for the drives that are attached:
In the example above the Drive Name is the same as the Model: ST31500341AS, the serial number is 9VS00J20 and the firmware revision is SD1A.
Device Manager Method :
Use Microsoft Windows Device Manager to see the model numbers of your disk drive.
- Choose Start | Run | type: devmgmt.msc
- Click Ok.
- Expand the Disk Drive branch to see the model numbers:
Seatools for Windows Method:
Download SeaTools for Windows which displays all of the required information.
After determining your serial, model and firmware revision please attempt to find your model in the following list of affected models. If you have one of these drives you can choose it from the list for model-specific instructions to update the firmware.
