Yes! You need a new drive cable. Here's why your WD worked and your Seagate was having problems.

Lets take a look at the WD drives' spec sheet: [|WD5000BEVT]. If you look at the line 'Data transfer rate (max)' its only a SATA II drive (3.0 Gb/s).

Now lets look at the Seagate drives' spec sheet: [|ST1000LM014] Seagate uses a different term 'Interface' Here we see SATA III (6.0 Gb/s), SATA II (3.0 Gb/s) & SATA I (1.5 Gb/s) are all listed.

Unlike your WD drive this drive has auto sense so it matches the SATA speed of the system, where as the WD is a FIX'ed SATA drive {SATA II only}.

Now lets look at your systems specs: [|MacBook Pro 13" (Mid-2012)]. If we jump down to the 'Standard Hard Drive section we can see the system offers a SATA III (6.0 Gb/s) interface.

The system is able to support the higher data rate but the cable can't so this explains why you are having problems with the Seagate and not the WD drive as the lower data rate is not stressing the cable.
