Very much so. In Solaris 10 there is a background daemon that isjust as an aside (I'm probably teaching granny to suck eggs here)
Windows has "Windows File Protection" which can be invoked by 'sfc
/scannow'. This will check for corrupted system files.
But I agree that in mission critical applications, it's best to do
error-checking in hardware, identifying memory faults *before* they have
the opportunity to cause corruption.
constantly checking out the hardware, and if it starts seeing problems
then the error log starts to get messages and makes recommendations of
what to start replacing before real problems arise.
In vms, the situation is a bit different but takes it a step further by
mapping out bad memory and disk blocks that are bad plus reporting it on
the operator console.
