I've just spotted a load of errors like this in my logs ...

Oct 15 08:02:10 scientia /kernel: wd0s3a: wdstart: timeout waiting to give command reading fsbn 10400 of 10400-10527 (wd0s3 bn 10400; cn 2 tn 37 sn 5)wd0: status ff<busy,rdy,wrtflt,seekdone,drq,ecc_cor,index,err> error 0
Oct 15 08:02:15 scientia /kernel: wd0: wdunwedge failed:
Oct 15 08:02:15 scientia /kernel: wd0: status ff<busy,rdy,wrtflt,seekdone,drq,ecc_cor,index,err> error ff<badblk,uncorr,id_crc,no_id,abort,tr000,no_dam>

(this was repeated at least a dozen times (except the first line which
only occured once), all within 1 second)

A few questions,
 - what is `wdunwedge'?
 - is this a serious problem with my disk?
 - what sort of thing could cause this?
 - should I just shut up and stop worrying?
