Hoping to get some help on this. I'm running Lion 10.7 on a Macbook unibody A1278 - I want to upgrade my 250GB HDD to a 1TB. I plugged in the 1TB using SATA-USB cables, formatted it and installed Lion.
I removed the 250GB and replaced it with the 1tb only to end up with the flashing folder with a question mark. I switched the drives back and plugged in again using SATA-USB and the 1TB seems fine!
My question is - why won't my computer recognize the new drive when plugged internally? When using the SATA-USB, I'm able to browse Lion on the 1TB just fine. I verified the new drive using disk utility and it says it's OK.
I know that a simple solution would be to reformat the drive, plug in internally and reinstall Lion that way, but I would really like to know why this way did not work.
Any help on this would be greatly appreciated.
