Hard Drive Cable or logic board?
I have a problem.
my mac visualized a folder with a question mark.
on "Disk Utility", my mac did not recognize the hard disk.
I replaced the hard drive and now my mac displays the disk but I can not format, partition and install the operating system.
I tried to replace the "Flat Cable Connection A1278 Hard Disk." but the problem remained.
The 2 hard drives work perfectly when connected to the USB port as external disks. I also installed the operating system and work.
I connected the 2 hard drives on another mac with sata and work.
The possibilities are 2.
1 The new flat cable I used, does not work well.
2 logic board. (Even if the system works with usb hard drives)
Is dit een goede vraag?
