Question Does vmstat -d give a count of actual physical writes/reads done to/from hard disk?
Hi,

I am trying to find the reliability of 'vmstat -d' for showing the actual physical writes on sectors on hard disk.

Can anyone please tell me if the numbers in the "sectors" field under "read" or "write" headers show a count of the actual write commands sent to disk from the low level driver?

More precisely, from this number, say n, can we be sure that n sectors on disk have been physically written to?
