Hi, I'ld like to add another disk in the blacklist regarding NCQ (libata-core.c). It is the disk model "HITACHI HTS541616J9SA00" with rev "SB4IC7UP". Currently there is a similar description, { "Hitachi HTS541616J9SA00", "SB4OC70P", ATA_HORKAGE_NONCQ, }, Notice the difference between SB4IC7UP and SB4OC70P. I have verified that the model name and rev are "HITACHI HTS541616J9SA00" and "SB4IC7UP" by adding printks in the kernel. The word HITACHI is all caps. Blacklisting does eliminate NCQ-related disk errors.
