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)
1. ASRock 880G Extreme 3 (with latest bios)
AMD Phenom II X4 965 Black Edition
1. BIOS is set to IDE mode
1. Western Digital WD2000JB-00GVA0
(single or master pin setting)
ULTRA SATA to IDE 100/133 Adapter #ULT40322
I had to exchange the SATA to IDE adapter for an IDE PCI Controller. After updating both the BIOS and Driver of the Controller, my computer's BIOS and Windows 7 was able to see the drive. I then used TestDisk to recover the partition (it saw the remnants of the original NTFS partition). I had been dreading this task for some time. It seemed so daunting; however, it was quick and somewhat painless. Thank you all for your help.
