What I find interesting is there appears to be two issues: 1) Drive quality - As far as I know the firmware updates have nothing to do with reallocated sectors, but of course that is a guess because Seagate aren't really telling us what they are fixing 2) Firmware issues, Drives freezing, Bricked drives etc Interestingly, my three drives with SD firmware have had zero issues to-date but I am seeing reallocated sectors on my one CC drive. Reading through this thread it appears that there are more reallocated sectors on the CC?? drives can others confirm? It would be interesting to tally how many reallocated sectors people have seen by original firmware and the number of hrs of uptime. So I have: Quantity: 3 Orig Firmware: SD17 (Upgraded to SD1A) Reallocated Sectors: 0 Hrs Uptime: ~1000 hrs each drive Quantity: 1 Orig Firmware: CC1H Reallocated Sectors: 4 Hrs Uptime: ~600 Probably would have been better to collect in a table but I couldn't get it to post correctly.

I'm drawing the same conclusions as well. SD1* seems to be OK as far as sectors, CC1H seems to have the issue.

Which brings me to another thought. Really, how bad ARE these "reallocated sectors?" I've got a bunch (20-30) on a few of the 750GB drives in my NV, still working fine.

If you equate them to being bad blocks, oh NO! we're losing space on the drive, so lets do a calculation.... I'm trying to find exacts, but lets say we have 16k sectors... that's 16kb per sector. Now lets say we have 10 reallocated sectors, that's.... 160kb. Next we account for a 1.5TB drive.... 160kb/KB isn't much.... even a few MB isn't much

I know it sucks but we've been dealing with "bad blocks" since we've had spinning metal disks in computers.
