A technician replaces a defective 250GB hard drive in a desktop with a 2TB hard drive.
After installation, the computer detects the new 2TB drive as a 250GB drive. Which of the
following should the technician do to fix this issue?

  • A. Reinstall the drive
  • B. Patch the OS
  • C. Upgrade the driver
  • D. Flash the BIOS

how can flashing the bios help? can exam-labs also provide explanation to answer, that would help learn it better, thank you.


Indeed in the first few answers there was explanation. please explain so as to help with understanding.


Yeah struggling with this one too ... surely the driver should be upgraded ???


Flashing the bios allows the BIOS setup to update any hard drive installed.


Has anyone confirmed this is the actual exam ?


guys i eather want to ensure if i am doing the actual exam ?


I just took the 901 and alot of the things I am seeing in here were also on the certification. Study the simulation questions, printers, RAID, protocols, setting up wireless network. This is a great study tool!


I can attest that this is almost word for word from the exam. I just took the exam last week (failed by 10 pts). I just discovered this website and am taking again today.


yeah took the exam and a lot of questions were the same. even worded the same



With a bit of research - Upgrading older BIOS versions for older machines means that you're likely updating it's Int13h software, a sub-application that older BIOS applications using a DOS format used to access or determine memory on your hard disk. This was phased out when the Int13h Extensions software update occurred, and the standard of using DOS based format gave way to modern IDE/ATA and SATA. So this question is a likely scenario for working on very old machines. I think it would help a lot of a Mod elaborated. This is an interesting question.


FWIW - I have only found 2, maybe 3 questions so far, plus one of the simulations that were on the actual exam (just took it yesterday). They are similar, and good for focusing on what you need to know, but they are not necessarily the same questions you will see, just examples. Good examples, but examples, nonetheless.

I believe this scenario is intending to show that the BIOS configuration was not updated with the new drive. If I'm right, the BIOS is still thinking the old drive is installed, so flashing the BIOS with the new drive installed allows it to create a new hardware image with the new HDD.


Stop trying to PASS the exam with the least amount of info that you would need!... Take a class and actually learn this industry and don't just be a test taker. Watch Professor Messers Comptia A+ 901 youtube videos....then come back and master this test. I bet you will pass the first time!!!


BTW... If the BIOS Firmware is not up to date it will not recognize newer ram. Flash the BIOS and then it will. None of the other answers will fix this issue. Please take a class!


General thought: Since POST is what would read the new hard drive after installation, simply entering the BIOS may be sufficient for the motherboard to go out and re-examine those connections. I've had a new build where I did similar and it worked. Of course, then making certain drivers are updated is still a good idea.
