I'm getting these messages during boot: error: failure reading sector 0xfc from 'hd4' error: failure reading sector 0xe0 from 'hd4' error: failure reading sector 0x0 from 'hd4' error: failure reading sector 0xfc from 'hd5' error: failure reading sector 0xe0 from 'hd5' error: failure reading sector 0x0 from 'hd5' they pop up soon after the Grub menu with a message to press ENTER to continue, and it times out in a few seconds if I don't press ENTER. These messages have been appearing for a long time, at least a couple of years and I've been too lethargic to investigate til now. I see no bad side-effects at runtime. I just did badblocks (read-only) on both sda and sdb (RAID-1 pair) which found no errors. I see nothing obviously related in dmesg, or /var/log/messages. I also have an external box (Venus DS3R Pro-2) with two drives, also RAID-1, that I use for backups. It is seen (after boot) as /dev/sdc. I'd have to pull the drives out of it and connect them to the SATA bus to run badblocks on them, as badblocks won't run on /dev/sdc. the nightly backups on to this box appear to run without issue. Anybody got any ideas on what this might be about? thanks in advance!
