Sluggers, Sit down, get a coffee its Jackanory time .... On a RH6.2 system with an Adaptec 29160 card and a Fuji 20GB SCSI HD I have been getting the following errors fairly consistently with original kernel: Info fld=0x165c5ba Current sd08:06 sense key medium error Additional sense indicates read retries error scsidisk I/O error dev 08:06 sector <sector#> <action ie cp, mv> Input/Output error Trying to decipher this; Info fld ?? sd08:06 --> SCSI disk, partition 06 (it is /dev/sda6 that is causing probs) Rest self explanatory Q1: Is the disk cactus? I have seen this problem on a completely different machine so I thought it was not h/w related. That's a different story. The SCSI controller and disk are both less than 12 mths old and that I have seen the same error on two completely different machines makes me sceptical it's a h/w problem (both have h/w less than 12mths - maybe I have a dud supplier?). When I installed this particular machine I got the install process to check for bad sectors (switching to M$ mode) surely the O/S would then not write to these bad sectors? I have down a SCSI card low level on the HD to detect/clear the bad sectors. [Aside, when I tried Solaris 8 on this machine it reported 10-15 bad sectors, not been able to get Linux to do that]. This will be a fairly important machine when released from testing so I want to try and make sure it is very stable. Would you suggest replacing the HD or are there more comprehensive tests I can do? I have tried kernel 2.2-18 and 2.4 in case that was the problem but the results where pretty inconclusive. Any pointers please? ------------------------------------------------------------------------ ----- Mike Earnshaw | Tech support is a fine art | e-mail in header Computer Systems | which once mastered, virtually | Tel : +61 8 9256 0023 Support | ensures loss of sanity. | Fax : +61 8 9256 1199 ------------------------------------------------------------------------ ----- ,-._|\ Union Switch & signal / \ 24 Bannick Court *_.--._/ Canning Vale, WA 6155, Western Australia v ------------------------------------------------------------------------ ----- -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://slug.org.au/lists/listinfo/slug
