2. Update Hard Drive Firmware

This issue is due to outdated firmware on the Seagate Pharaoh Hard Drive and is NOT necessarily an indicator of a hardware failure. The permanent solution is to update the firmware on the Seagate Hard Drive.

To resolve this issue permanently, follow these steps:

1. Confirm the Hard Drive is eligible for the firmware flash. The drive model can be verified in Device Manager or in the System Bios in drive details
2. Locate a blank USB Flash drive (the flash utility will delete any data contained on the specified USB drive)
3. Download the Seagate Firmware utility from the Dell Support site (Click the search box and search for ST250DM000 to find the most current firmware to download.)
4. Boot to the USB drive and follow the utility instructions
