Generally speaking if you are using hdparm for tuning it means we need to fix something in the ATA layer so you don't have to ! > I guess it would be safer not to reattach drives after power > fail...

For good or bad its very hard to tell if a drive randomly powers off or we merely get a bus reset in the ATA case. In the SATA case we do at least get the relevant events to handle it nicely as we *should* see a DevExch event. We also can't tell a power fail event from a hot drive swap, so we most definitely want to re-attach the drive, just so long as we ensure that it comes back on a different device node.
