What to do with data left after wipe

[goldfinger88]

I am wiping a 120gb external hard drive today and notice there is one line of data. The data is unreadable so it's not issue but since I'm selling the drive, I'd prefer nothing to be on the drive when the new owner gets it. Will that date go off when the wipe is finished or how should I delete it or should I delete it? Thank you.

Use "MiniTool Partition Wizard" it lets you see all the partitions and you can completely wipe the drive and format it properly without the leftover space from Eraser.

Also this recoverit data recovery can help to retrieve data from a external hard drive
