Hi, I'm seeing a lot of the following messages lately: Mar 29 21:02:01 pixie kernel: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=13554983 Mar 29 21:02:34 pixie kernel: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=35376691 Mar 29 21:04:42 pixie kernel: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=13574483 Mar 29 21:12:25 pixie kernel: ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=2665375 Mar 29 21:12:56 pixie kernel: ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=38935999 Mar 29 21:14:53 pixie kernel: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=2170339 Mar 29 21:15:36 pixie kernel: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=51982907 Mar 29 21:23:45 pixie kernel: ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=415 Mar 29 21:24:57 pixie kernel: ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=41387775 Mar 29 21:25:27 pixie kernel: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=38754719 Mar 29 21:26:02 pixie kernel: ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=53056287 Mar 29 21:29:03 pixie kernel: ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=34612991 Mar 29 21:38:25 pixie kernel: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=8346079 Mar 29 21:52:59 pixie kernel: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=4663 This is a IBM Thinkpad T23 with the original disk installed. $ uname -a FreeBSD pixie 6.2-RELEASE-p3 FreeBSD 6.2-RELEASE-p3 #0: Sat Mar 24 02:43:20 CET 2007 root@pixie:/usr/obj/usr/src/sys/GENERIC i386 I've searched the net to gather some evidence wet wether this is a sign of a dying hard disk, but I'm still not sure. Some postings state that this kind of message isn't that bad as long as there are retries left and suggest a configuration error. Well, the Laptop had it's own kernel configuration until recently (I forgot to save some configuration files before I installed DesktopBSD) so I kind tell wether the appearance of these messages relates to the new installation in any way. Is it possible that this is a configuration issue, or should I get a replacement for the disk? Christian
