Why my new HDD is not recognised?
My Macbook frozen suddenly and presented the ? folder on startup so I assumed that the HDD (a WD blue 500Gb) was busted. I plugged in the original Toshiba drive I keep for emergencies and surely enough the Mac booted up. I bought a 1TB hybrid Seagate as a replacement. Problem is that the Mac does not recognise it. I even formatted in using usb caddy via disk utility (Mac OSX Extended Journalled) and tried again to no avail. Worst even, I checked the WD drive using the usb caddy and the WD diagnostics tool (in a Windows PC). Aparently, the disk seems to be fine.
Which brings me to the milion dolalr question. If this is no HDD, it is SATA connector. And if it is SATA connector, how come one of the HDDs, the Toshiba one, boots normally? beats me.
Is this a good question?
