Maverick on Weybridge + WD2.5THDD

Hey, they don't fry.  :(

Remember, SATA-class HDD running massive concurrent IO nonstop is not the
environment or market it's sold into.  For that, you'd need a moderately
more expensive Enterprise-class SATA HDD.  Please follow me to the display
case, in the back...

Harry,

I started a stress test this afternoon and it is still going, the test
spawns 32768 threads, which is little over 1/2 max threads, and each thread
write/remove 1GB files (in a loop). Hopefully some of these threads will
write close to the end of the disk as well. The HDD is warm to the touch,
hopefully I wont fry the WD drive ;)


Cheers

UEFI install missing.

would like to know if the file system is really functional all they way out
to the end of the disk.

but it is really time consuming. Checking to see if the filesystem is
corrupt is still a question in my mind (does fsck check this for disks and
file systems >2.2 tb)?
