  1. It's not a helium-sealed drive. I don't think there are any permanently sealed He drives that are not in the 3.5" form factor. As for helium leaking out over time, that's why the permanently sealed products are designed the way they are, such that whatever leaks out is so small relative to the total volume it really won't be an issue for the expected lifetime of the drive.

    WDC Red Pro 8TB Too Quiet

    It must be a helium-filled drive. Moving that much air means it's well-nigh impossible to achieve those acoustics numbers (unless it's a typo ). Spinning in helium results in much less fluid drag, a major contributor to noise. Not sure about the weight. The gap between the 8TB and all the other capacities lead me to believe they are at least 2 distinct platforms.
  3. Pretty much. Cloud has helped a lot, but the volumes can't compete with what used to go into the PC market. Net results is layoffs and difficult times for those in the industry. Combined with many markets replacing magnetic storage with flash, the overall market size keeps shrinking. I don't think it will completely disappear anytime soon, but it will certainly be a lot smaller than it was in its heyday.

    Scratched platter

    Drive (and data) are toast. The fall caused the heads to smack into the media, leading to the head crash (that ring-shaped scratch on the disks). It isn't repairable, although data recovery might be possible, albeit *very* pricey.
  5. Been a busy few weeks for announcements from WD. First the Unisplendour investment, then MOFCOM lifting the hold separate requirement, and now buying SanDisk. I do wonder if the former led to the easing of the latter, though. The industry is going through a period of churn and shrinkage. Definitely an anxious time for those in the field.
  6. MOFCOM required the hold separate bit, not the EU.
  7. I don't think it'd be for keeping the motor spinning. That would take way more capacitance than is likely to fit on those boards. But it might be enough power to finish flushing the onboard cache. Press releases are always fun to try and decipher ...
  8. No, they are using 5 platters. The WD subsidiary does not have a 6-platter platform, only the HGST subsidiary does. The current industry form factor defines 6 side mount holes and 6 bottom mount holes. The 2 closest to the SATA/SAS connector are required, while the others are optional (but each drive must provide at least 4 of the 6 holes for both side and bottom). Earlier revisions of the spec only defined 4 and 4 holes. The locations themselves haven't changed, though.

    Are fans any threat to a hard disk?

    In storage, it doesn't really matter, provided they're kept within specs, generally -40C up to 70C or so.

    Thanks for sharing this news. I remember his postings from the early days, too.
  11. Media and heads are all binned, AFAIK. It's not so much that highest performance goes to enterprise, but whichever product needs the densest capacity. That doesn't necessarily mean the highest reliability, though. If two product lines use identical parts, then you can bin the higher quality items to enterprise, but often the different product lines are mechanically different so that's not feasible
  12. Hard to say if it's a manufacturing issue or it's loud by design. By that, I mean, design tradeoffs to achieve some other performance metric, rather than actual defective manufacturing or assembly. Generally, slow changes in position shouldn't cause odd sounds, but dramatic ones can make the drive unhappy and possibly cause damage.

    Opened hdd platters...

    Yes. Drives with lesser capacity will use either different parts to achieve that or software to disable the "bad" surfaces to block off the unusable space.
  14. Kevin has already answered. Just about all disk drives use die-cast aluminum bases; those markings are casting markings, such as flash or parting lines. Often, a trim die is used to get it roughly to size, then more detailed cleanup happens with someone holding the base against a sanding belt. The voids are bubbles (porosity) in the aluminum. I think I've seen a few that used stamped steel bases, but that's only going to be with the really small form factor drives. So absolutely nothing wrong with your drive.

    Problem with my External HDD

    Does the drive even try to spin up? Did you plug in both SATA and power to the drive? If that doesn't work, then you could try a board swap as shown in the YouTube link Brian provided above. Beyond that, there aren't any options for the average user short of professional data recovery.
