I am looking for a piece of software that will be able to check the HDD sectors and make sure they have been wiped, I am currently using CESG approved data erasure software which guarantees the wipes on the drives that pass.
A lot depends on what pattern has been used to overwrite the data.
The most basic approach appears to me as follows:
1. If that's some flat pattern, like FFs or zeros, then install WinHex, open the hex search tool and enter e.g.
!00 for zeros.
2. If drives are being filled with random data, then download some credible data recovery software like
UFS Explorer and perform a scan.
To speed the things up you can define regions to search/scan.
