The announcement was made by Chief Minister Prithviraj Chavan after a meeting of the state cabinet held at Vidhan Bhawan to review the mishap.
"We will try to restore hard disks and recover data from them. We will seek help of Nasscom, cyber cell and even foreign experts," Chavan said.
All files pertaining to the Adarsh scam have been handed over to CBI, so there was no question of it affecting the probe, he said.
Over 2.27 lakh files have been scanned, he said.
There may have been lacunae in fire safety systems, we will look into it, he said.
Mantralaya will be out of bounds till the structural safety audit is complete, Chavan said.
The ministers have been asked to cancel their tours and supervise work of restoring documents in their office, he said.
