Isn't "BIOS reset password" a security flaw?
According to this article Dell Support can help a user to gain access to data after forgetting the HDD password:
Once Dell Support has provided the reset password, you enter this when prompted and then press Ctrl + Enter to complete the process.
... the BIOS should accept the reset password, clear the password, and allow access to the hard drive.
Isn't this a security flaw? Shouldn't only someone who knows the HDD password have access to data?
Does other PC / BIOS / motherboard manufacturers provide similar means?
What is a good resource for understanding how hardware based disk encryption (FDE?) works and how the procedure described above is possible?
