How we handle your equipment and data
Data erasure, physical destruction and reuse inspection take place at our Technical Center in Koshigaya, Saitama.
- STEP 1
Every unit inspected on arrival
As soon as equipment arrives, we inspect every unit and register it into stock, checking it against your asset list if you provide one.
- STEP 2
Nothing erased before you approve
You can review the asset list online. Data erasure starts only after you approve it.
- STEP 3
Erased and logged one by one
Each device is erased with the method you choose (software erasure or physical destruction), and the technician and date are recorded.
- STEP 4
Certificate of Data Erasure
We issue a Certificate of Data Erasure (PDF, for a fee) listing the method, date, technician and serial numbers for every device. Data erasure is free for equipment we buy.
