>Description:
Found problems with the work with hard drives
Hitachi HDS721010DLE630
Seagate ST2000L003
Disks in ar0, ar1.
When installing the system copies the data from the DVD, DVD stops and HDD led stays on - the system writes something, then again for some time writes well.
The same when trying to update system (portsnap)
Then everything is repeated. Tested all the hardware. Everything works if the HDD is an old release sata-2
operating system is a strange behavior when working with these HDD.
below are available at the server where you can check it out.
No data on the server. You can test your patch to work with disks directly on it.
>How-To-Repeat:
You can see it on SSH:

91.203.146.30 port 2232
user: Denis
passwd: freetest
root
freetest###9

Run
#portsnap fetch
then
#portsnap extract
then try to work with FS (login-in, copy something, edim files) - all moving by periodic jerks
