Keywords: HD I/O Error, mkpart, cylinders, fdisk, V386/3.0-L2.2 Message-ID: <163@hawkmoon.MN.ORG> Date: 3 Jul 88 22:01:15 GMT Organization: One of the Eternal Champions - Eagan, MN, 551232267, USA Lines: 50 I'm getting these HD I/O Errors whenever i access my dos partition on drive #1. I was about to go and use mkpart -A to map-away those bad sectors when i realized, upon closer inspection, that the cylinder (i'm assuming that "Cy:xxx" is the cylinder number -- please correct me if i'm wrong; i don't have much (read "any") documentation on these error messages (:-() is "804". But the drive only has 512 cylinders!!! How am i supposed to map that one into the bad sector table? Although, i assume using relentless logic, the error message is perfectly correct; cylinder 804 on a 512 cylinder drive would have to be considered "bad" i'm afraid... And this message only comes out (reproducable at will) when i do a dosdir on the second drive. Doing a "dd if=/dev/rdsk/1s3 of=/dev/null" did not produce any error messages, nor did a "mkpart -v disk01" for that matter. Can someone explain to me what is going on? Or maybe tell me how to calculate the appropriate bad sector to feed to mkpart -A so i can access my dos-space? Thanks in advance... $ mkpart -tv disk01 Device /dev/rdsk/1s0 device type: 0 serial number: cylinders: 512 heads: 8 sectors/track: 17 bytes/sector: 512 number of partitions: 9 $ dosdir c: HD I/O Error: Fun:20 Cy:804 Hd:0 Sec:1 Status:59 Estat:10 Drstat:B0 dosdir: read /dev/dos/c: I/O error $ fdisk /dev/rdsk/1s0 Total hard disk size is 511 cylinders.
