Why is "S.M.A.R.T." consuming so much boot time?

Helo, I´m new here; it´s my first question here. And I do´nt know I´m right here.

My question: My Boot-HD is an OcZ SSD with 128GB. S.M.A.R.T. seems to consume after each PC-(Re-)Start about 135 seconds before booting is going on.

The screen shows in this time continuos: S.M.A.R.T., the HD-Number: 0, the device-character C: and the Name of the device OcZ. After this time the screen gets black and 5 seconds later the Windows logo is shown and Windows is starting. And after this Windows needs only about 10 seconds and the start screen is ready.

It´s annoying to me to loose as much time with any boot / PC start.

In BIOS I did´nt find an item like "S.M.A.R.T." or similar that is "enabled".

Is the "S.M.A.R.T."-Function in the SSD built in? How can I stop this testing?

Or needs Windows 10 pro (since 5 days ago installed on this HD and this PC) so much time and does not show what Windows is doing in this time?

Hi, Blonder_Hans. Wikipedia talk pages are for discussing improvements to the article, not for general help or discussion (WP:NOTFORUM). You'd better ask some place like https://superuser.com etc. -- intgr [talk] 12:00, 20 March 2018 (UTC)[reply]

Attribute "235 POR_Recovery_Count" on Samsung SSD?

I have a Samsung SSD 840 EVO 1TB and in smartctl it is showing the Attribute with ID "235 POR_Recovery_Count". In the Wikipedia article ID 235 seems to be something else, there it is called "235 Load/Unload Cycle Count" so i assume that manufacturers use that ID differently. But what is the meaning of "POR Revovery Count"? If someone has an answer it would be nice if he could add it to the article. --37.209.114.151 (talk) 00:08, 27 January 2019 (UTC)[reply]

SMART was designed for HDDs, and then forced to work with the first gens of SSDs that were all designed as drop-in functional replacements HDDs, thus requiring a lot of "creative" re-purposing of attributes originally focused on moving heads and rotating media. Little of this creativity is industry-wide and well documented. Samsung's web pages may have something, or it may not. Some SMART reporting tools use different definitions from the hardware that's reporting the SMART info, leading to a lot of confusion.
There's very little WP can do to remedy any of this.
But, just for you in this one case, I'll have a guess based on my working with SSDs: it may be counting times when the device was powered off abruptly, requiring any incomplete updates that were in progress from RAM to flash to be restarted and completed when power is restored. Note that's assuming "POR" means, per an industry standard use, "Power On Reset". --A D Monroe III(talk) 21:36, 26 June 2019 (UTC)[reply]

Attribute 90 / 0x5A - NAND Health

HGST's 20TB OptiNAND HDD models introduce a new SMART attribute -- NAND Health, ID = 90 / 0x5A.

The document also refers to Helium Level (22 / 0x16) as "Internal Environment status".

Requested move 28 October 2022

S.M.A.R.T.Self-Monitoring, Analysis and Reporting Technology – Not the primary topic over SMART criteria, which can also be written as "S.M.A.R.T". * Pppery * it has begun... 19:24, 28 October 2022 (UTC) — Relisting. — Shibbolethink ( ) 15:38, 5 November 2022 (UTC)[reply]

I'm questioning the primary topic argument based on what Abbreviations.com and Acronym Finder are saying, and I think that is more significant than pure page view count.
I have read the relevant MOS bits about a dosen times and thought hard about this, and I think this article should keep this title the way it is written now, possibly with an addition to it, as this subject is pretty much solely known by its acronym. The full meaning is obscure to the vast majority of even expert computer users. From WP:NATURALDIS: However, do not use obscure or made-up names. (my bold marking) Note that the exception about natural disambiguation for acronyms in page titles is general and not an absolute, stated in the first sentence you quote in your reply. And this subject doesn't really have a natural disambiguation. Again … do not use obscure … names.
I think both titles are distinctive enough, but if you and possibly others insist on a more detailed title I would go as far as saying that "S.M.A.R.T. (computing)" or something along those lines is a better title than writing the full meaning of the acronym, and that that is within the MOS, because this is the common name by far, and the expanded form is obscure and thus natural disambiguation is invalid. SMART analysis isn't a computing subject even though it can be used in computing.
My unawareness of SMART analysis wasn't an argument, just a note. And it speaks to my disadvantage. You never having heard of this subject before means neither of us can fully assess the importance of these subjects in relation to each other. Therefore none of us can truly argue for a primary topic.
And I can't find any mention of points/periods not being allowed in acronyms as mentioned by SMcCandlish below. On the contrary, the MOS gives examples with periods in between letters.
Sorry for the gibberish-esque last sentence, I was in a hurry and had to cut it short. I have fixed the spelling, but I don't know if it's proper English, but I keep it that way anyway for history. Kind regards. --Mango från yttre rymden (talk) 20:20, 11 November 2022 (UTC)[reply]

Why remove SMART attributes?

Whole section on what known ATA attributes was removed this November. I always found that info extremely useful. If you think that this does not fit the SMART article, i propose to move it to its own page. Gryxx (talk) 09:44, 10 November 2022 (UTC)[reply]

I have nothing more to say than my edit summary: WP:NOTMANUAL/mostly unsourced/excessive detail * Pppery * it has begun... 14:22, 10 November 2022 (UTC)[reply]
As for mostly unsourced i would rather have a baner informing of that rather then information completely removed. As for excessive detail, as i suggested move SMART attributes to it's own page. Gryxx (talk) 14:37, 10 November 2022 (UTC)[reply]
Describing the functionality of a system is hardly a manual. Describing the operating of a system, that is a manual. A list of attributions is certainly encyclopedic. Regards. --Mango från yttre rymden (talk)
