It’s sometimes very important and necessary for you to use hot swap data recovery technologies to recover the lost data from the patient drives in your data recovery lab.
The following are the hot swap instructions for Hitachi GLA and SLA families:
1 – Save all SA modules from patient and donor drives;
2 – Record SA co-ordinates from patient NVRAM into donor NVRAM (SA Top I tihnk is only important) then repower;
3 – Start Hitachi utility and make offline start, select patient modules ~zone and ~resf to load from;
4 – Write to donor patient ~zone and ~resf and repower;
5 – Make offline start again, then write all patient SA modules to donor;
6 – Repower and should be ready for hotswap.
