Yes, of course. I have a ddefinitive answer now. After some days of use, the disk failed again. I changed the drive to another computer, and after compiling some ports, some disk read failures came again, causing segfaults. I was paranoid, and just to confirm , I tried to install debian linux on it. I could not even fisnish the install cause some disk read failures lead to segmentation faults. The disk is now disassembled on my desk. The encloruse is removed. I am looking at the spinning disk, the heads, the control system. If is indeed an incredible beautiful machine that the man created. Just to destroy it, I plug the cables with the enclosure opened. I created a ffs file system on it, I mounted it, I copyied some files on it, some were copyied, some not, the errors were frecuent. I has been an amazing experience seeing how heads move to find the data on the disk. The disk is on the trash now. 2 weeks of free time wasted, but many things learned! Thank you very much. Tomorrow I will buy a new HD only for OpenBSD. Ramiro.
