No, harddisks generally have write cache disabled because it is a potential problem unless you have a UPS. Like I wrote, we check the setting whenever we install or replace a drive. AFAIR, we had to make a small utility, hdparm did not support it. Maybe it does now, I don't know.
Ah. I was trying to find how to enable or disable it in hdparm and couldn't see it.
It looks like it is the '-W' option now.
-W Get/set the IDE/SATA drive´s write-caching feature. Missed it. I greped for "cache" and "buffer". Careful, lower case -w does something very dangerous. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
