Hard Driver Not Visible During Installation

Question

Trying to install Yosemite on Dell Optiplex 755 using Yosemite Zone 10.10.1 image.

 

Hardware Profile:

 

- CPU: Intel C2D E6550

- Graphic Card: nVidia GeForce GT 610

- MB Chipset: Intel Q35 (ICH9DO)

- Network: Intel 82566DM

- Audio: ADI1984

- Hard Drive: Seagate SATA 7200.10 ST3250310AS 250GB

 

Boot Flags Used:

 

-v cpus=1 ncpi=0x3000 PCIRootUID=1 GraphicsEnabler=Yes

 

Problem:

 

The boot process went fine, and got to the welcome screen without problem. After opening disk utilities to format partition for Yosemite, the hard drive was not visible. 

 

SATA mode is setup to ACHI. The hard drive currently has three NTFS primary partitions. One of them has windows 8.1 installed. I was planning to use one of the remaining two for Yosemite.

 

Screen shot for disk utility is attached. 

 

thanks

I am answering my own question: You need to add IOATAFamily.kext to the USB drive, and set BIOS SATA mode to legacy.

I also have this problem. Disk Utility cannot see my partitions. Can someone give us a hand?

Where did you place the kext file to on the disk image ?

If you cannot determine whether the drive is spinning:
Boot the computer and listen carefully.
Shut the computer down.
Disconnect the power cord from the computer itself.
Disconnect the power cable from the hard drive in question.
Reconnect the power cord to the computer itself.
Boot the computer up to see if the drive sound was audible before. And,
Then repeat, only reconnect the hard drive and listen for it to spin up.
Switch power cables with a device like a CDROM or DVDROM drive, so that you are using a known-good power cable.
Check the power supply on your computer to determine whether it is providing sufficient electrical power to operate the drives and devices you have in your computer.
If the drive is still not spinning, connect it in another computer if possible.
Connect the drive in a SATA-USB enclosure or something similar if possible.
If the drive does not spin up after all of these steps, please visit the Dell Optiplex 755 Manual for help or ask Dell Experts for support.
