What make/model of drives are you using? Have you checked to see if there
are firmware updates available for your drives (especially if you're using
recent Seagate models)?

What make/model of controller?

What kernel version are you using? Recent kernels have had a lot of work
done on the SATA code. My understanding of that error message is that the
kernel believes the drive has been hot(un)plugged.

Are you using latching SATA cables?

Are you aware that internal SATA connectors are only designed for 50
insertions?  Is it possible that you're approaching the end of service life
for the connectors on your cables, discs or controller?
