In short, I've found two things: a) cfdisk might work while fdisk does not. Interesting. My personal experience has been the opposite: cfdisk writes (and demands) better formed partition tables, so sometimes crap that fdisk can read/write will not work with cfdisk. But of course, YMMV. Since we are bringing up alternative fdisk programs, what about sfdisk? I wouldn't put money on it, but it won't hurt to try. W -- Willie W.

That seems to have been it. Testdisk did indeed write a new partition table, minus one of the partitions which it insisted on deleting so I suppose something was wrong with it. After much time taking and restoring backups my main system is now running again and i can run fdisk. I'm surprised at this, because a seek error sounds uncomfortably like a hardware problem to me. Maybe some particular error in the partition table confused fdisk and cfdisk. Anyway, thanks for the help, Nikos and all those who offered it. -- Rgds Peter.
