Solution for: #59: getFatBlock error when upgrading Seagate Barracuda 7200.11 firmware

Turn off both AHCI and RAID options for the SATA controller

The solution appears to involve switching off AHCI and RAID for SATA. On the Dell Precision T5400, press F12 to enter the boot menu, choose Setup to enter the BIOS.

Go past the list of SATA drives to the last few options. One of the screens should present three options for the SATA mode: AHCI, RAID, and the pure ATA-based option. Once you select ATA and reboot, the FreeDOS boot CD should work. It will still report "error reading partition table drive" errors, but it should no longer block on the "getFatBlock" error.
