PCB failure is extremely rear event and almost never causing data loss, unless original microcode in onboard ROM is destroyed or erased intentionally.
Data Recovery Chances and Rates
The drive is reliable and may work many years without any problem. Plus, even if it crash, the successful recovery rate (at least in our lab) is above average for this type of drives.
