AFAIK, there was no report of increased transmission failures. Two known problems with these firmwares are 1. timeout on FLUSH if NCQ is in use on certain drives 2. bricking after power off (so, the failure is almost always during BIOS probing during boot) > (I'll paste my dmesg as I don't know enough to tell if this is the same > issue as the other seagate drives--I trimmed the repetitive parts) > > [ 7520.699730] ata2.00: exception Emask 0x10 SAct 0x7ff4f SErr 0x400100 > action 0x6 frozen > [ 7520.699734] ata2.00: irq_stat 0x08000000, interface fatal error > [ 7520.699738] ata2: SError: { UnrecovData Handshk } This is transmission error. Most common causes are power related or unreliable connection especially if backplanes are involved. Is the problem still reproducible? If so, can you please try to move it to different power connector and SATA port and see what changes?
