  1. I see there have been no forum comment threads for news posts since Nov 19. When I followed a comment link, it took me to reddit. Which I've never signed up with. Is SR discontinuing the forum here? I notice a lot of spam lately, even after I reported one. Spam still up days later. I actually wanted to comment on the Seagate dual-actuator story. They talk about HAMR, release it to trusted partners for testing ... and we hear nothing more. No public release. They talk about dual-actuator, now released to trusted partners for testing ... and no word on public availability. The future seems to be putting up a fight about becoming the present. Are the HAMR drives experiencing issues in testing? That would explain why they haven't shipped yet.
  2. linuxbuild, you do realize this thread is from 2014? It's doubtful any drive mentioned above is still manufactured today. Your link post in the other (current) thread suffices.

    Hard drive errors, time to get a new one?

    You can use WikiPedia's key to SMART values. 1) Read Error Rate = vendor specific value. Desired to be "low", but that's all we know. Interpreting it would vary by manufacturer. 7) Seek Error Rate = another vendor specific value. We don't even know if high or low values are desired. 184) End-to-End error = desired to be low. This attribute may predict drive failure. The last one is the only one I'd worry about. On top of that, you're getting recurring disk errors. I'd replace the drive. You're backed up, right? In case the drive fails unexpectedly?
  4. The only diff between generic- and Mac-friendly drives is how they're preformatted. Mac drives come formatted HFS+ (Mac OS Extended - Journaled). PC drives come formatted NTFS or ExFAT. Just reformat as needed - it's the same drive either way. Why do you need data recovery of your backup drive? Unless your main drive(s) have failed, your backup is just a backup. Swap the drive with WD, plug the new drive in, reformat as needed, and let Time Machine start over. ps - you contacted Apple Support. You didn't contact MAC - no such party.
  5. As you're only using 250 - yes, you can use a 480-512 GB SSD. If your data is growing slowly, then a ~500 will hold you until SSD prices are better.
  6. Did you open it up, to look over the real drive inside? Either WD has begun making 2.5" 5TB drives ... or they swallowed their pride and bought drives from Seagate. Finding a Seagate drive inside a WD external - now that would be a front-page story.
  7. As 16TB drives already require 9 platters, a conventional 18 needs 12.5% higher overall density. Or about 6% linear density increase AND 6% tracks increase. Are these the first MAMR drives? We keep getting promised HAMR and MAMR drives any time, and that further increases are not possible without. Only to keep getting conventional size increases. This isn't exactly a complaint, but they should keep their stories straight.
  8. All the comparison drives were other Seagates, in 14 or 16 TB. Perhaps some HGST, WD, and Toshiba 14s for comparison? Any update on the Toshiba 16 TB? It was announced months sooner, but I've yet to see it anywhere.

    HDD and slow sectors

    No reallocated sectors. Very low start counts and run time. Low max temp. I'd chalk it up to driver or firmware hiccup every 28 GB or so. If your backup data is critical, change drives. Otherwise, I'd pay attention to it in the future, for any misbehavior.

    HDD and slow sectors

    Can you dump and post the SMART data for your drive? If it really is reallocated sectors, that would be parameter 05. Seems the most likely, but it could also be a few other things. Like a poor cable, or internal problems. If it's your only backup, and the data is critical, I'd be concerned. But I'd like to see the SMART data rather than guesswork based on a performance benchmark.

    HDD and slow sectors

    That curve looks normal to me.
  12. Are these the first HAMR drives? Also, is it really the first shipping 16TB drive? Toshiba announced a 16TB conventional (non-HAMR) months ago, without a shipping date.

    2,5" 2TB HDD

    That's not quite accurate. HGST did not sell their entire 3.5" business to Toshiba. Only enough to allow Toshiba to immediately enter the consumer market as a real competitor. HGST retained plenty of 3.5" assets, and continued to sell them. With newer models introduced for years.

    2,5" 2TB HDD

    This one is a 3.5" drive.

    2,5" 2TB HDD

    I have both the Samsung M9T and Toshiba L200 2TB drives installed. The L200 is a good bit faster in my benchmarking. Never been certain if it is SMR. M9T has been in service for 3+ years. L200 for about 6 months. No issues with either.
