Retail VS Shucked drives, MHDD platter scan results

[Pawelr98]

As someone who does a bit of data hoarding, I decided to share my small results of checking shucked drives against a retail drive
Drives are:
8TB - WD80EDAZ-11TA3A0 - Shucked WD MyBook - white label WD HC320

12TB - WD120EDGZ-11B1PA1 - Shucked WD Elements - white label WD purple WD121PURP

16TB - WD161KRYZ - Retail WD Gold 16TB purchased directly from WD website


The pattern I see is that the shucked drives are something like Quality-Control rejects.
More sectors showing instability which may evolve into bad sectors.

A sample of three is not much, but I would love to see results from others.
MHDD is an old piece of software (~2006), running on DOS, easiest way to boot is to use Yumi tool.
Older uefi or bios preffered for this software to work.

Scanning all the platters takes time, but I would say it's worth it, as one can weed out troublesome drives before they get into a working setup.

The heck is a shucked drive?

A shucked drive is, I believe, an external HDD removed from its enclosure. I once removed a 750GiB Seagate HDD from an external enclosure and it developed bad sectors after a year of use as an internal HDD.

The heck is a shucked drive?

A hard drive or SSD that has been removed from the external enclosure it was sold in for use as an internal drive.

Removal of external drive's drive from its enclosure for use inside case

Damn ninjas

A drive pulled out of an external enclosure.

It’s North American slang.

I had to lol at the example.

“The process of removing, peeling or discarding the outer covering on food items such as nuts, corn and shellfish. The husk is peeled from an ear of corn, the shell is removed from a nut, and the outer shell of a shellfish such as an oyster or a clam is also similarly removed or "shucked."”

Well that would definitely help explain why shucked drives are cheaper than retail....

I only found out what "shucked" drives are a few months ago. Never knew what it meant.

Cool story: the first drive I bought to shuck was a Hitachi DeskStar 1TB. Bought for the cool sum of $170 US. I also got a short tour of Thomas Jefferson National Laboratory, as that is where the dude that sold it worked!

It's what happens to shellfish who ask too many questions...

You wanna go for a drive, mussels? You don't.

I found that if you get these symptoms, then it's most likely an HDD with a bad board or bad cache on the HDD board: (possibly oxidation or corrosion on the HDD PCB!)

MHDD finds nothing wrong during the scan, but Windows installation keeps failing, often in random spots and/or Chkdsk terminates with a false insufficient-disk-space error.

Or the system keeps reporting corruption, even when MHDD didn't find anything wrong.

 

[OneMoar]

not sure I trust MHDD its a hella old and dos-based
edit and the comparison is what?
you are testing 3 Different drives here?
Pattern? What Pattern?

 

[RJARRRPCGP]

Oh, in my case with what looked like a PCB fault on a Western Digital WD5000AAJS HDD, IIRC, it had the symptoms I mentioned, but not even so much as unusual lag with the MHDD platter scan.
There also were no other errors reported by MHDD.

This explains why i'm bipedal these days



Heaps of my drives are from externals, i've never had any issues

Edit:
Now to be clear i get a lot of second hand utterly f*cked 2.5" external drives, but that's because the owners treat them like poopoo and beat the crap out of them. SSD's have saved us from that stupidity continuing - i've even had to stop family from whacking the enclosure to 'stop the noises'

I'm from Pacific Northwest Oyster area, so I know shucking as a term.

Fun unrelated fact (as if this is on topic at all): It's a very fact paced industry to make a livable wage (per unit pay), and people who do it longterm tend to lose fingers.

If I could compare more drives, I would.
That is unfortunately not possible with the income I have available.

Normally I would have purchased another external 12TB for redundancy but I decided to spend more on a retail 16TB drive, for the 5 year warranty and the ability to check whenever there are noticeable differences in the quality of the drive.

If other users could fire up the scan on their new shucked/external and retail drives, there would be more data to get some conclusions.

MHDD does scans the same way other programs do, it's that most programs just flag good/bad while MHDD provides actual access time for all the sectors. There are some more modern programs but they are Windows based, which means there's an element of uncertainty like the OS trying to access the drive, running a dedicated program under DOS removes that uncertainty.

awww shucks!

Get shucked!

and the ever popular: Go Shuck Yourself!

I used to see people bring me borked old Passbooks (WD). Dropping them almost guaranteed something inside would break. I would offer to mount the HDD inside their case if it was still good.

OT, but maybe relatable, Blue Valkyrie is about to die!

Yep theres more, just our local one.

Off topic (and im very sorry but it will be my only one)

I read this in Joe Pesci's voice

omg I've totally facepalmed.

Thus far based on the amount of HDD used in the data hoarding reddit from shucked hdd, they general perform as similarly as retail version and reliably enough albeit slower. I got tons of externals due to their price I am curious of their reliability themselves. External hdd are derated retail version running at lower rpm which makes them rather excellent for quiet builds. My 7200 retail WD ultrastars are loud in comparison.

As far as I know, they are not derated.
Even if the drive reports 5400rpm, it is often in fact 7200rpm.
WD introduced 5400rpm "performance class". If you take measurements based on seek time, vibration frequencies or just use an MHDD command "rpm" you will get 7200rpm. Three ways to confirm the real rpm.

WD80EDAZ reports 5400rpm, but it's 7200rpm without any doubt.
