Replaced hard drive in MBP, still won't work
I just installed my replacement HD (SATA 2.5) in my MBP but all I get is a flashing ?. The faulty drive would get further than that but would just never mount.
The SATA cable looks to be the next replacement but it seems as though I'm not doing something basic here, so before I buy a new cable, I was hoping to get some input.
I didn't have the tool to remove the mounting screws on the old HD, so I just put the new one to see if it would work. Could this be the reason the new HD isn't being recognized?
I guess there is also the possibility that the new drive is defective but that seems unlikely.
As some background, a large (maybe 2 lb.) book fell on the keyboard as I was attempting to remove it from a shelf. A few days later, the computer started to fail.I didn't think that could cause an HD failure but it seems related.
Any input would be greatly appreciated as I don't have the funds to send it to Apple for repair (it's a refurb from them and warranty has expired.
Thanks.
