You’re welcome. I’m glad that you were able to get your data back.
I would perform a write zeros on the drive using our Data Lifeguard Diagnostics. This way everything will be wiped off the drive. Then partition and format the drive and see how it behaves.
If the drive just had partition corruption then it could be fine and it just needs wiped and re-partitioned/formatted. However, if the drive starts to have problems again or fails a diagnostic check from Data Lifeguard Diagnostics, try changing the data cable, in case it is a bad USB cable. If it still happens I would recommend replacing the drive. I included some links below that may help you.
