ONLY FOR MAC OSX!
Use with caution, as it wipes your disk entirely. :)
I cannot be held responsible for any data loss or damage that might occur.
- smartmontools (installable with homebrew - only needed for erase-disk.sh)
A simple script to quickly wipe all data and create a simple exFAT partition.
Mostly I used this to quickly wipe multiple disks in bulk for example if I want to resell them.
You can connect multiple disks e.g. via USB to SATA/M.2/IDE Adapters.
The script also dumps technical information and S.M.A.R.T values to a textfile which naming is based on the serial number of the drive (since it is unique).
This takes a long time, so make sure you take this into account!
| Command | Algorithm |
|---|---|
| 0 | Single-pass zero-fill erase. |
| 1 | Single-pass random-fill erase. |
| 2 | US DoD 7-pass secure erase. |
| 3 | Gutmann algorithm 35-pass secure erase. |
| 4 | US DoE algorithm 3-pass secure erase. |
This should only be used for HDDs, not SSD.
