After reading

tried the recommended diskchecker.pl

I always get:
Total errors: 0
even if I tested with with a HGST HTS721010A9E630 that the vendor's
datasheet
(http://www.hgst.com/sites/default/files/resources/TS7K1000_ds.pdf)
advertise as "
Designed for low duty cycle, non mission-critical applications in
PC,nearline and consumer electronics environments, which vary
application to application
"
Since it is not, a high end disk, I expect some errors.
Why? Just because a disk isn't enterprise-grade doesn't mean it has to
lie about fsync, which is the only thing diskchecker.pl tests for.
