No.
Without "verify on" command, I can alter txt file fine, changes survive 
MS-DOS reboot, so there's no caching that fools me
With verify on I end up with  zero byte 2.txt file,  after typing command 
echo 1 > 2.txt

at the moment, my "SAN" is a linux host running vbladed for AoE target.
At topic start, I was using iSCSI target using ietd

Is anyone able to re-create this problem?
Is it some race condition, where the sector verify-read operation is started 
before sector write is finished?
