My hard disk drive is not detected in the system BIOS

If your HDD is not being detected by your portable system trouble shooting is fairly direct:

  1. Remove and re-seat the hard drive to ensure the connection to the system is effective, sometimes there is enough play that over time the connection loses contact due to thermal expansion/contraction and re-seating the drive resolves.
  2. Reset the BIOS default settings. This can be done from within the BIOS (F2 at boot for most systems, F1, F10 and DEL are the other most common entry prompts, watch you screen at boot for BIOS/SETUP access prompts if unsure) Check the Hard Drive Controller Settings/SATA controller settings and write them down, and once you reset the BIOS defaults, check them again. If they have changed, set the controller setting back to the pre-reset setting to avoid 0x0000007B controller errors on reboot. Most Phoenix brand bios can be reset by pressing F9, Enter. Others will have a maintenance section where default settings can be restored. After resetting, save changes and exit this will force re-numeration of all devices by the system, including the hard disk drive. If using a desktop chassis and you have multiple controllers, swap cables with a know working controller (Usually the Optical drive) and see if the drive is detected on that cable and controller and the optical drive on the HDD controller.
  3. If the Hard Drive is still not detected, you can remove the hard drive and install it in a USB external drive case and see if the drive is detected on another system. If it is not, then the drive has failed, and needs replacement. If the drive works in the USB adapter then the controller is suspect on the system the drive was removed from, and a motherboard replacement is likely the end result.

i have an acer aspire 5536 G, it had windows vista on it. Now everytime i try to turn it on it says that there is no operating system found. what can i do to restore it?


An error of no operating system found, is often an indication of a failed hard disk drive (HDD) in the system (The hard disk drive is where all data including Windows is stored)
  1. If the system is equipped with a floppy diskette drive, remove the diskette from the floppy drive and reboot.
  2. Re-seat the hard disk drive. (From time to time due to expansion and contraction the HDD may lose contact and is no longer detected)
  3. Once re-seated, reset the BIOS defaults (normally F2 at boot) then there is normally a setting to reload defaults. Resetting default settings forces the BIOS to re-detect all peripherals connected to the system.
  4. If you still get that error at boot, then it is very likely the drive no longer is functional and will need to be replaced.

Nothing happens when I plug this in. I've tried eSATA and USB, both with the power adapter. The blue light comes on but nothing else. The hard drive works in other enclosures so I know that isn't the problem. Enclosure is brand new. Not sure if it's driver issue or not.


Your assumptions are leading in the right direction.
  • The blue light would just be denoting power to the device the red light would denote drive activity. The limitation on this enclosure is that its white papers states a "Hard Drive Compatibility: 320GB HDD capacity", but I have seen people use a 500GB drive that seemed to work. If your using a drive larger then 320GB this may be an issue.
  • The enclosure HDD combo is Plug-N-Play via USB so this would mean drivers most likely are not the issue. I don't believe drivers are even packaged with the device which would mean they use protocol standard drivers from the OS.
  • Make sure that you are not hooking the USB up to a external USB hub (especially a bus-powered one) while trouble shooting as it may not provide enough power. Connect the drive up to system USB controller directly while trouble shooting.
  • I believe this device has the ability to hook up 2 USB cables at the same time for extra power (mainly while using the eSATA connection). Try hooking up the USB mini-B connector and the USB +5VDC connector and then hooking both up to the system on two different USB ports. This should then correct the possibility that your drive may not be getting enough power.
  • Lastly, the enclosure could have a faulty IC on the PCB. Exchanging it would provide the answer for that.
Hope this was helpful. Thanks for visiting FixYa.com

You should not need a driver for it. Assuming you are using XP or Vista, the disk should be supported directly by the OS.
Have a look at external HDD troubleshooting.

The first issue is how you are connected. If it is IDE or SATA. Next is to ensure that the bios settings are set to enable the corresponding connection. Next ensure you have the cords or ribbons seated properly in the drive as well as the board, ensuring the power connection is secure. Good Luck!
