I/O errors

[Wade Preston Shearer]

I received the following errors in my LogWatch report this morning:

>  --------------------- Kernel Begin ------------------------
>
> WARNING:  Kernel Errors Present
>    Buffer I/O error on device fd0p10...:  17 Time(s)
>    Buffer I/O error on device fd0p11...:  17 Time(s)
>    Buffer I/O error on device fd0p12...:  17 Time(s)

…etc (about 20 lines of this)

And…

>  ---------------------- pam_unix End -------------------------

> Nov  7 13:39:36 end_request: I/O error, dev fd0, sector 0
> Nov  7 13:39:36 end_request: I/O error, dev fd0, sector 8
> Nov  7 13:39:36 end_request: I/O error, dev fd0, sector 16
> Nov  7 13:39:36 end_request: I/O error, dev fd0, sector 24
> Nov  7 13:39:36 end_request: I/O error, dev fd0, sector 32

…etc (about 375 lines of this)


What does this mean? Bad sectors on one of the hard drives causing  
read/write errors?
