Some things to do : Follow the example in the scsi(8) manpage to set the AWRE and ARRE attributes on the disk (if they aren't already). Because this is a write operation, you should get a reallocation (assuming it's a bad sector). Ring Seagate tech support and ask them about the numbers. Info is obvious, 'asc' is the Additional Sense code, the drive is reporting FRU 11 as faulty, and I'm not sure what the 'sks' value is. FWIW, I was getting FRU 11 errors on an ST11200N (with AWRE and ARRE enabled) and managed to cure them with a low-level format. YMMV, in particular FRU 11 on the 11200 may not match FRU 11 on the 15230. You're getting a 'deferred error' because the drive has delayed the write operation as an internal optomisation, and has only just discovered that it can't actually write it out. -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
