Jeff Hello
We have in our machines several sata (mostly maxtor-segate) disks in an array.
These disks generate too many ata-io errors at clients sites.
>From raid1 code I have learned that a re-write sometimes fixes a disk.
Question: Why ?
Question: Does it always work ?
Question: Does rewriting a slow sector also reduces a disk error rate,
does it make any sense ?
thank you

You need to post much more information to get anyone on the list interested.
* lspci -nn
* boot log (/var/log/boot.msg on some distros or the result of dmesg
after boot)
* kernel error messages (dmesg after errors)

I am not trying to fix any problem. I am asking a genera question. We
found that rewriting over a slow sector for several times, speeds up
the read from this sector.
My question is, does it make any sense to you,or Mr. garzik ?
thank you
