My original question (part of it):

I received many emails which helped me to eliminate possible problems.
Most people told me to check the 7053s firmware revision. At least
7053-106-211 Rev. 2.23 works with these new and big disks (Fujitsu
M2392 Swallow and Seagate Sabre 2.5GB).
In this case, the revision was right but the brand new 7053 controller
was damaged! I got another controller and everything works OK.
I replaced the Fujitsu disk with a Seagate Sabre too even if the
problem wasn't the disk but the controller (and got another 500 MB of
disk space)....
It seems to me that those "header not found" errors are caused by one
of the following reasons: bad cables, bad disk, bad controller or bad
controller version...
