reducing ATA retry count

Hello,

I've got an ATA hard disk with bad sectors. I want to read the good sectors quickly, replacing the others with zeroes. However, when I'm trying to read it sector by sector, reading each bad sector takes 20-150 s. Before diving into the code, I'd like to ask whether there is an interface (like ioctl or /proc) to disable bus resets and re-reading attempts if the first read operation fails.

Please cc to me, I'm not subscribed.

Thanks in advance,
Baurjan.
