-- CMR

-- Features: S.M.A.R.T., APM, 48bit LBA, NCQ (credit @cba123)
-- @vancouverie: "WD Ultrastar air filled one no TRIM so it's not SMR but run hot"
-- @rob187 "Sitting on a desk in the open air with no active cooling, this bare drive idles @ 50°C". "Helium filled drives are around 27°C"
-- @vancouverie: "Air filled one , so no need 3.3v mod".

- Old Internal hard drive: These have EZAZ in the model #
-- These have green top box (credit @cba123) and are helium filled.
-- @Lucidlife " Got one 24 Nov 2020 and asked the clerk to get one from the bottom of the stack (older ones) and luckily I got another EZAZ. S/N started with numbers (1Exxxx) instead of letters (WVxxxx) I have a WD PR4100 4 bay and no mod for me."

- Warranty: 3 years manufacturer or 2 years Costco
-- Note: if shucking, keep the enclosure in case of warranty claim. Record the matching enclosure serial # and hard drive serial #. Some report having warranty denied if they don't match.

Before shucking:
- Test the drive to make sure no problems.
- Confirm the internal hard drive model # & make sure someone hasn't returned it with a used internal drive in it (used hours?)

You can also do a Conveyance self-test with it. "Conveyance self-test is intended to identify damage incurred during transporting of the drive." It's only slightly longer (5 min) than a short self-test. I test all new drives with it before deciding if they need to be returned/exchanged." costco-western-digital-mybook-8tb-199-9 ... #p32465621


Shucking:
- @rob187 "I’ve got it down to a science. On the top side you slip in 4 credit cards along the cracks, card just barely has to be in the crack. Then push firmly on the small rectangle from the other side and the whole cage will release." costco-western-digital-mybook-8tb-169-9 ... #p33528509
3.3v pin:
- If hard drive is not recognized, then may be due to new 3.3v pin.
- Some say the 3.3v pin is not a problem in the newer air filled drives.
- 3.3v pin does not require modification for use with Synology NAS (credit @tvisforme) (costco-western-digital-mybook-8tb-169-9 ... #p33545946)

******** Background info / FAQ *****************

Shucking
- Remove the internal hard drive out of an external hard drive (i.e. remove the enclosure around it).
- This allows the internal hard drive to be placed in a NAS, computer, PS4, xbox, etc.
- A shucked hard drive is often cheaper to buy than the retail version of the internal drive.
- External hard drives are slower than the internal hard drive.
- As of 2020, $20/TB is a good price.

Before shucking:
1. Do not write any data to the hard drive. It sounds like this can cause encryption issues making the internal drive hard to read after shucking.

2. Test the drive to make sure no problems.
- sounds like for WD, "WD Data Lifeguard" is being used
- sounds like for Seagate, their "seatools" software is being used.

3. Confirm the internal hard drive model # & make sure someone hasn't returned it with a used internal drive in it (used hours?)

Helium vs Air-filled
- Helium filled are quieter, cooler and use less energy (~20%?).
- They are a newer technology, and helium can reportedly leak out, so life span for these drives is not yet known.
- How to tell if hard drive is air filled or helium filled
-- "Under the SMART attributes look at the Helium level attribute." (credit @[Keigotw])
- @[Keigotw] "hard disk sentinel - the trial one and then you can see model and if any Helium motor in SMART INFO" https://www.hdsentinel.com/download.php costco-western-digital-mybook-8tb-199-9 ... #p32464560


SMR vs CMR:
"CMR: It depends on your application of the device. If you constantly read/write/move/delete cmr is the way to go.
SMR: If you read/write and you don't move/delete smr works just as well."

@[mindabsence] "Centralized file storage is also a very useful NAS use and falls into "everyday user" type of needs. Our house has several laptops, a desktop, a tablet, many phones, etc. We store all our digital photographs, videos, documents, etc. on the NAS. Each user of the house has a login which gives them access to their personal files + relevant shared files (family photo albums, etc.). Now no matter what device they're on, or even if they're away from home, they can access their files. The computers themselves really only store applications and games - everything else is stored in the NAS, and the NAS also takes care of ensuring those files are backed up and protected against drive failure too! Second to that, I also run Jellyfin which you've already covered the benefits of for most users too." costco-western-digital-mybook-8tb-169-9 ... #p33534893
