Comment 2 for bug 182996

i order to solve above error messages, here is how to proceed:

open a virtual terminal, and type the following:

sudo hdparm -w /dev/hdc

after the above command error messages stop, and in the "dmesg" you can see the following:

.....
[ 175.999491] hdc: DMA disabled
[ 176.044912] hdc: ATAPI reset complete
.....
