Cisco FTD 1010 - Error opening disk0:/ Input/output error

[jigargajra]

We have multiple Cisco FTD 1010 running on ASA image have been facing issue with disk.

asa-eureka-ca# dir

%Error opening disk0:/ (Input/output error)
asa-eureka-ca# fsck disk0:

The ASA is operational but wont save any data, or reboot.

I have multiple devices alerting with same error. The units are breaking within 1 year of service.

Have seen a few cases where the ambient room temps were too high.

can you run: # sho env temp    ?

If you unplug the appliance for a while (i.e. 30 min) does this temporarily resolve?
