i couldnt tell you TBH, but any crash on a system has the opportunity to corrupt a hdd and in some cases the only fix is a format. i recently corrupted my registry (cant remember how) but i done a recovery with windows 7 (via usb) and instead of it fixing the issues, it simply copied a fresh registry to my system, causing all registries from installed programs to be lost, and in turn most of my software would no longer run.
which is why i am still setting up a fresh install (which is not always a bad thing).
this is from windows help on the setting
but from experience, in the event of a crash, only the data that is recent gets 'lost', but there is always that 'chance' of corruption. so use at your own risk, but i always use it on my main hdd, but not on my backup drive for obvious reasons (thats why its a backup drive )
Cache flushing
“Write caching” in a storage device refers to the use of high-speed volatile memory to collect write commands sent to data storage devices and cache them until the slower storage media (either physical disks or low-cost flash memory) can accommodate them. Most devices that use write caching require that power be supplied continuously.
By default, Windows employs cache flushing. This means that the system will periodically instruct the storage device to transfer all data waiting in the cache to the principal storage media. When you select Enable write caching on this device, you turn off these periodic commands to transfer the data. Not all devices support all of these features.
If high data transfer performance is your paramount concern, you should enable both settings: in the Removal Policy section, select the Better Performance option and in the Write-caching policy section, select Enable write caching on the device (if the system hardware and storage device support these features).
