Caveat Emptor -- "Bad magic number" error


Just a heads up, as I have seen storage devices that are unusable for my purposes in GNU/Linux surface, of late.
Without naming names, and for example only, I see all recommended storage devices mentioned here are a POS except for two.


But maybe it is just my experience. Are there others who would like to contribute their negative expereinces, just to help the n00bs make good choices?

What's the point of that statement if you don't tell us about the good ones?
And how did you determine that anyhow? I doubt you tested all the SSDs in that article???

FWIW, I bought mine a few years ago and have no problems with it.
Code:
Disk /dev/sda: 111.8 GiB, 120040980480 bytes, 234455040 sectors
Disk model: WDC WDS120G2G0A-
I still use spinning rust in addition to that.

Didn't want to be accused of Spam, as some here are overly sensitive to it, it seems.

Okay -- Samasung and Cruxial ar the ones I have had good experiences with, and the others have given me grief in one manner and/or by one of their lines or another.

Freedom of expression IS crucial! LOL

Isn't that a gross misinterpretation of what I wrote, and mostly missing the point?

Thank you for condescending to clarify a little. Do you mean the exact Samasung and Cruxial models from the article linked? And you also tested all the exact other models, or just manufacturers, or what?
And what exactly is good/bad about these models? Just saying something is good or bad without specifying is - well, not very useful.

Talking

@ondoho

I love your tongue-in-cheek response!

Adata SSD -- ordered two form seller on ebay. Unusable. "Bad magic number". Returned.
Sandisk -- apparently embedded software; after writing with zeroes to rid, unusable (this was 2+ years ago) Junked.

In truth, I cannot say about the Team(whatever) device, as I have not tried that brand.

If I am missing how to make any SSD or USB device usable in Linux after receiving the 'bad magic number' error, please advise!

THANKS!

Seller on ebay....?????
New from factory? Used? Refurbished?

SSDs are similar to USB sticks in the way they fail. Once it begins you just can't do much with them and they are junk.
If you really want to have good performance only buy them new and you will usually be able to have a reasonable service period. Used is a toss up - they may or may not work.

With that said, I have been using a Sandisk SSD for the past 2 years on my daily driver and so far no errors whatsoever.

I understand the frustration with 2 bad experiences like that, but that is anecdotal and not scientific proof.

Oh, thanks for catching that. The typo ("two form seller") threw me. Yeah, another important aspect. Like all sellers on $online_store are 100% reputable!

Adata SSDs were new in package.

If anecdotal=experiential, I agree.
(yeh- the name in LA for ebay seller was foreign, not N American).
But, is amazon any better?

"waffle, waffle, waffle" LMAO

--------------------------

i have 30 year old ide that are still error free

you have a long way to go to be telling me what an anecdote is

----------------------------

i've heard tons of linux and non-linux SSD warnings (meaning compatibility or early failure both). i checked the list and was like "um, if i upgrade i'll be careful"

someone weighing in saying "warnings are un-scientific". that just isn't true. HCL's are a linux reality.

Bad hardware out of the box is a reality in any environment, although very rare. If it was common the manufacturer would quickly lose all credibility and go out of business. Warnings OTOH are unscientific unless they are backed by adequate proof.

Why in the world would you limit your comment to linux? Why also would you not acknowledge that ALL manufacturers bend over backward to make certain the OS will support their hardware for the giant (microsoft) and mostly ignore the little guy (linux)
Code:
Mirriam Webster dictionary

Definition of unscientific
: not scientific : not based on or exhibiting scientific knowledge or scientific methodology : not in accord with the principles and methods of science

-----

Definition of anecdotal
1: based on or consisting of reports or observations of usually unscientific observers
anecdotal evidence
health benefits that may be more anecdotal than factual
2a: of, relating to, or consisting of anecdotes
an anecdotal biography
b: given to or skilled in telling anecdotes : ANECDOTIC sense 2
my anecdotal uncle
3: of, relating to, or being the depiction of a scene suggesting a story
anecdotal details

-------
I stated the the info from the OP was anecdotal since he was relating personal experience instead of details from an exhaustive study.

I don't understand why anyone would be upset by someone calling a rock a rock. Yes, warnings are acceptable. But for someone to try and say their few experiences apply to all of that brand is simply scare tactics unless backed by proof.

I have had a couple HDDs fail in < 1 year. I have also had many more identical make and model that run for decades. I have never had an SSD fail to date. I am sure most have had similar experiences.
