Hi all, Short question: is there a hard disk drive integrity checking utility for Unix systems that will detect problems with a HDD (similar to scandisk in windows)? Background: I recently installed a 3rd IDE HDD (Quantum Fireball) into my FreeBSD 4.4 system (FreeBSD munkboxen.mine.nu 4.4-RELEASE FreeBSD 4.4-RELEASE), and all was fine for a while until I started getting the following errors: <snip="/var/log/messages"> May 22 18:29:26 munkboxen /kernel: ad2c: hard error reading fsbn 160 of 80-95 (ad2 bn 160; cn 0 tn 2 sn 34)ad2: DMA problem fallback to PIO mode May 22 18:29:26 munkboxen /kernel: ad2: DMA problem fallback to PIO mode May 22 18:29:26 munkboxen last message repeated 8 times ... continues for various blocks ... </snip="/var/log/messages"> The particular file system is a ufs slice which I dedicated for use with /usr/src (I keep all my sources on that partition/slice). The fstab entry looks like this (the pertinent partition entry is commented out to stop it from choking when the system boots - fsck just halts and I go into single user mode otherwise): # Device Mountpoint FStype Options Dump Pass# /dev/ad0s2b none swap sw 0 0 /dev/ad0s2a / ufs rw 1 1 /dev/ad0s2f /usr ufs rw 2 2 #/dev/ad2c /usr/src ufs rw 2 2 /dev/ad1s1e /var ufs rw 2 2 /dev/ad1s2e /home ufs rw 2 2 /dev/acd0c /cdrom cd9660 ro,noauto 0 0 /dev/fd0 /floppy ufs rw,noauto 0 0 proc /proc procfs rw 0 0 Any help much appreciated, -- Jez Hancock - munk@munkboxen.mine.nu http://munkboxen.mine.nu - FreeBSD network http://www.freebsd.org - Probably the best OS in the world...
