"... Data corruption occurs on disks sometimes, e.g. the write to disk didn't record data correctly on the platter and any attempt to read it returns the corrupted data. This may just be 1 bit and it may only occur once in millions of writes but it is known to happen. ..." You wrote just about disks first, so I responded just about disks too. After this, you responded with "disks and IO subsystems". And now in bug tracker, you again write just about disks. Please: 1) Read atleast Error rates and handling in http://en.wikipedia.org/wiki/Hard_disk_drive 2) Be clear on what problem do you have 3) Think about RAM at first - in PCs without ECC, in servers with just very simple ECC, much weaker than used in disks and on the tapes 4) ... and what about the caches, all storages and all communication paths along the path? What all we know about them? Almost nothing? Checking just the spool disks (with all related subsystems needed to check these) is very narrow view of such a complex thing -- Rudolf Cejka <cejkar at fit.vutbr.cz> http://www.fit.vutbr.cz/~cejkar Brno University of Technology, Faculty of Information Technology Bozetechova 2, 612 66 Brno, Czech Republic ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
