Hey folks, dealing with an issue regarding a Hitachi Travelstar 7K1000 2.5 drive. Been messaging back and forth with the guys that I purchased this off on ebay.
I've sent the drive back for inspection and they claim that the drive is in working order and they're prepared to send it back to me.
Unfortunately for me, when I had installed the drive into my Macbook Pro laptop, the drive showed up on Disk Utilities but failed to format as a MacOS drive saying Drive could not be initialized.
During reboot, it says Drive not recognized or something like that.

Currently, I'm in the middle of asking for a refund but they're pushing me to get them to send it back including a small postage fee.
I'm worried that it would be more than likely that once I retrieve it, it won't work.
Also, a refund would apparently cost me %25 of what I paid for.

I've received a free new replacement caddy which also didn't work.
The drive didn't work on another MBP when I plugged it in using an SATA to USB converter
I'm running the latest Mavericks.
What should I do!?!?!?

I've also just been reading about people having issues regarding different SATA speeds.
Apparently one user had no trouble with the Travelstar 7K1000 installed within the original bay.
The problem is, when I've swapped the drives around, my laptop wouldn't boot.
If the possible solution would be to have the hybrid ssd hdd on the optical bay caddy and the hitachi 1tb hdd on the original hdd bay, how would I get it to boot plus keeping the original files etc?
