I have here one disk (ST3000DM001) that starts pre-clearing and after 38% it stops with the following error messages in the log. Re-starting pre-cleairing brings it to 38% again and it hangs there and disappears from the OS. Any idea is greatly appreciated?

It sounds as if the drive may have a problem.  It would be worth including the SMART report for the drive.  It could also be worth attaching the drive to a PC and carrying out the manufacturers check (Using SeaTools I think?).

Thanks. Will hook it up to a PC (only have an XP here for this, should be ok).. SMART I get the following:

 

# smartctl -A -t short -d ata /dev/sdm
smartctl version 5.38 [i486-slackware-linux-gnu] Copyright (C) 2002-8 Bruce Allen
Home page is http://smartmontools.sourceforge.net/

Smartctl: Device Read Identity Failed (not an ATA/ATAPI device)

A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

Try running the command as

smartctl -a /dev/sdm

.  That works for me to get a report.

Same error message.

Will check with Seatools as soon as I get to the server.

Interesting.  It sounds as if this drive might be really sick and need RMA'ing.  At least SeaTools gives you the diagnostic information that Seagate RAM process wants.

The disk may need a power cycle before it responds.
