Hello, You wrote: “The idea of the additional step in the "extensive test" is to write back something different, to refresh the sectors. Not only the stored data, but their capability to hold different kind of data for a possible later re-use, re-format.” You also wrote: “This way the cond...

Re: "Extensive test" option during hard disk surface refresh

Hello, I have a question about Hard Disk Sentinel Professional (which I didn't use yet), more precisely about the “refresh” feature: “Read+write+read test (refresh data area)”. I am aware that when writing data to an hard disk, the data is temporarily held into a cache (even after the write is compl...
