    Helium Filled Hard drives

    http://www.pcworld.com/article/26227..._capacity.html

    I heard about this. Focused on the business sectors. But I predict once they get all the kinks out, and the money to put back into R&D, the consumer will begin to see them, having single platter 1TB drives @ 7200+ RPM and running cold, and fast, and being cheap

    we might start to see < 320GB drives disappearing

      Re: Helium Filled Hard drives

      My company created a large electromagnet for WD which readied some sort of special-material platters. I wonder if it has something to do with this... hmm.

          Re: Helium Filled Hard drives

          I asked this in a newsgroup: Has anybody tried putting a hard disk in an unside down empty aquarium and filled the chamber with helium? I'm assuming if the HD's vent is placed on the bottom, it will let the denser air fall out and the helium rise into it.

              Filling a regular HDD with helium will make the heads crash into the disk surface.
              A correct air density is required for regular harddrives to work.

              It is why they can not be put inside an unpressurized box on an airplane while operating for example, or in space.
              Using helium would get around these problems, all the while increasing performance and data density as the article states.
              I'm kind of impressed by this, I read about it a while ago, it's so simple yet so effective!

                  failing hard drives after sitting for years...
                  by eccerr0r
                  With the discussion about water pumps failing when cars sit for a while, I wonder what people have seen with hard drives. Do people see hard drives failing after being sat on the shelf for a long time unpowered versus a hard drive that's at least powered up at least once in a while, say, weekly?

                  Wonder if it's worth spinning up the spare spinners once in a while to keep the bearings lubricated?

                  Wonder how I should best keep my cold spares for my RAID "fresh" for eventual failures of the working drives. Was thinking about keeping a hot spare but that's another...

                  Evaluating Mechanical Hard Drives SMART Data in Linux (Ubuntu) Using the Disks Utility.
                  by abajor
                  I've gotten into the habit of Looking at peoples Mechanical Hard drives with a Ubuntu thumb drive to boot their system.
                  I understand the raw values are not really uniform between manufacturers, but I have noticed that high seek and read error raw values at the very least correlate to a drive that is going to have sub par access time, and extremely slow OS booting.
                  The odd thing is I've often seen very high seek and read error rates on drives with fairly low on time.

                  Does anybody have any other takes on evaluating smart data? I've used Crystal Disk Info, It seems to present...

                  **Need Help Unlocking BIOS and Hard Drive on Dell Precision 5820 Tower**
                  by federalhouse
                  Hi everyone,

                  I'm in need of assistance with a Dell Precision 5820 Tower. The BIOS is locked with "Dell Security Manager," preventing access to the HDD-1 hard drive.


                  **Background:**

                  I recently purchased this Dell Precision 5820 Tower from a recycler who salvages equipment from abandoned office spaces. The computer was left behind by its previous owner and was password locked. Given that it can run Windows 11, I saw this as an opportunity to upgrade my setup.


                  **What I've Tried So Far:**


                  1. I accessed                  ...

                  what to do with faulty hard drives?
                  by ChaosLegionnaire
                  i have several dead/bricked (not detected, doesnt show up or making constant clicks of death) and faulty bad sector hard drives. im moving house soon and need to get rid of some dead weight.

                  i thought of selling them for parts or not working but they are quite heavy and shipping each drive internationally via local post is US$23 each. im using some of the drives as gym strength training dumbells by putting 4 of them in a box to make a 3kg dumbell. but since im moving i cant carry the deadweight with me. any ideas what to do with them that is cost-effective for ppl like me...

                  Best Overall Amazing Back Up Setup? 1K-4K Budget! Software + Hardware? Help!
                  by NeedsPractice
                  I remember a lot of people before when my hard drive failed told me that I could do a couple of amazing things with backing up data. What stuck out is two things...

                  1. Software that will backup your data live via a cloud solution or over the internet without having a corporate cloud product.
                  2. Get a storage tower with hard drives and load them up.

                  What I mean is there software out there that you can install on your computer. You tell it which data you want backed up. Lets say your main PC with (2) hard drives and (8) hard drives connected to it via a tower....
