    My Hard Drive is not seen by either my Bios or Windows


    by sadoj ·

    I know this is has been addressed before; however, the responses did not solve my issue. I will include more detail about my issue in hopes of a better diagnoses.

    I accidentally changed my external hard drive from NTFS to HFS when prompted, while connecting via USB to a macbook. Now I can no longer see the hard drive via USB or direct connection to my PC.

    I took it out it’s case and noticed it has an IDE connection for a motherboard that only has SATA connections. I purchased an IDE to SATA Adapter and installed it into my computer…….nothing. The BIOS and Windows still does not see this drive.

    I am aware I have two separate issues. In order to correct the file structure issue I have to gain access to the drive.



    The hard drive powers up both in the external case and with the adapter.

    1. Windows 7 Professional x64 (with all updates)

    Mother Board:
    1. ASRock 880G Extreme 3 (with latest bios)
    AMD Phenom II X4 965 Black Edition

    1. BIOS is set to IDE mode

    Hard Drive:
    1. Western Digital WD2000JB-00GVA0
    (single or master pin setting)

    ULTRA SATA to IDE 100/133 Adapter #ULT40322

      BIOS Error Logs . . .

      will tell you if the electronics just happened to get fried around the same time you converted it to HFS

      if there’s nothing appearing in the BIOS error logs

      you could try attaching it to a Mac again and using the disk utility to remove the partition and giving it back to the windows machine with no partition

      if the Mac now can’t see the disk either, then the electronics are hooped

        Bios error Logs and Mac Disk Utility

        Who Am I Really:

        My tech level is about average, as such, I am not sure how one would look for BIOS error logs via my motherboard. I will try that.

        I am intrigued by you recommendation for the mac. I will try both of your suggestions and post the results.

        Thank you

          are accessed when the system is started,
          you enter the BIOS instead of allowing the system to boot into windows

          BIOS Entry keys are usually displayed
          > Press F2 to enter setup / BIOS
          > Press Del to enter setup / BIOS

          if you web search for your Motherboard’s / System model’s BIOS setup entry key
          the correct key should be display in the first page of search results

          once in the BIOS setup
          you can look through the various settings pages for the error logging

          ie. on Intel boards it’s F2 to enter the BIOS and the BIOS system error logs are located in

          Advanced > Event Logging

          if you have a bad disk
          fried electronics
          toasted media
          the errors will be logged

          I suggested using the Mac’s disk utility
          since a Mac was the last system to see the disk in a working / usable condition

      Did you power up your “IDE to SATA Adapter”?

      If no power is going through then you will get nothing. Try another adapter just in case that has gone.

      When you have some info from your hdd then go here:

        Powering up IDE to SATA Adapter

        In reply to Did you power up your “IDE to SATA Adapter”?

        Peconet Tietokoneet:

        Thanks for your response. The adapter is fully powered. there are two power connectors and one SATA connection. the adapter also has an LED that illuminates when adapter is powered.

        I looked at the site you suggested. Am I to understand that DiskPart attempts to restore or create the NTFS without destroying the data? My tech experience is about average and those steps seem daunting. An example would be partition size, I have no clue what value to use; however, I will try your suggestion as a last resort or if I can somehow find a way to image my data drive then I will throw everything at it to restore it.

        I appreciate yours and other suggestions I have received and I will give them a try and post the results.

        Thank you

      Important changes relating to age discrimination in UK employment law became effective in October 2006, with implications for all types of appraisals and job performance and suitability assessment. Ensure your systems, training and materials for appraisals reflect current employment law. It’s helpful to understand these recent laws also if you (young or old) are being appraised. The UK (consistent with Europe) Employment Equality (Age) Regulations 2006, effective from 1st October 2006, make it unlawful to discriminate against anyone on the grounds of age. This has several implications for performance appraisals, documents used, and the training of people who conduct staff appraisals. For example, while not unlawful, the inclusion of age and date-of-birth sections on appraisal forms is not recommended (as for all other documentation used in assessing people). For further guidance about the effects of Age Equality and Discrimination on performance appraisals, and other aspects of managing people, see the Age Di

      try the following:in windows xp

      connect the NFS hard drive as an external harddisk using USB cable. boot the pc on windows xp professional. go to start – control panel – administrative tools – computer management – then expand the storage link. click on disk management – check if hard disk can be seen.
      right click on the hard disk then choose change drive path. choose any letter. this should work.
