With smaller 2.5″ Seagate drives, the motor cannot spin if the heads/sliders are on the platter. When this happens, you will hear the drive beep.
This most often occurs due to a drop. It occurs more often in smaller 2.5″ drives, because the motor in 2.5″ drives is less powerful than the motor in 3.5″ drives: in a damaged 3.5″ drive, typically, the motor would spin the platter anyway.
Even when the heads are stuck on the platter and the drive is beeping, there is hope for successful data recovery: so long as the drive has not been opened. Attempts to unpark the heads by opening the drive if you are not skilled in data recovery, or hitting the drive to get them unstuck, often does damage to the heads or platters that is irreversible.
The difference between a more affordable data recovery and an $1100+ data recovery often lies in what was done to the drive after it started beeping.
