Someone did a re-installation of his Operating System of the C: drive using his computer's 'Acer hidden recovery partition' (the alt+f10 procedure). Then he chose 'do not back up personal data (this will wipe the entire C: drive)' during the recovery process and his system was 're-installed'. All of his personal data was in that C: drive.
Does an Acer hidden partition recovery install zero-format the disk?
Serious issue: He didn't backup his data. His data is now lost, supposedly. Would it be possible at all for me to recover all of his 'my documents' data (important financial data, years of family pictures, ..)? The data is crucial.
I called up Acer (some low level helpdesk support girl answered) and they said "no it's not possible". I don't believe them. Would it be possible to recover his data with data recovery software?
His computer: Acer AZ5610
