More safe hard disk

[piker]

Only some simple words
- "Soft updates" on all slices
- and one small option in
/boot/loader.conf
hw.ata.wc=0

I understand the softupdates but why disable write caching?


If you're running a server or doing some thing where data integrity is mission critical and probability of power failure high I could understand it, but for a desktop ?



I always thought the point of write caching was to speed up write performance, under the guise that many desktop users might prefer faster returns from writes operations then worry about the system going down before the hard drives write cache has been flushed.
