This ST9500423AS drive has "AF" on the label (FW 0005DEM1):
I wouldn't assume that. I have noticed that manufacturers often prefer to sneak new tech into the marketplace so as not to alarm their customers. For example, I saw one tech site which reviewed a Seagate drive without mentioning that it was a helium model.CrazyTeeka wrote: ↑Wed Nov 15, 2023 4:31 pm There's no AF anywhere on the label on this drive. But I assume they don't put AF on the label unless its 4k logical/physical.

It's bullshit, and in my experience pending and reallocated are usually accurate regardless the drive brand.CrazyTeeka wrote: ↑Wed Nov 15, 2023 4:13 pm What if SMART just doesn't feel like sharing much on this drive?
Maybe the answer is to stop trusting SMART.

.. he basically brushed it off by telling me "experience". It's a load of mumbo jumbo and I explained him why. 9 out 10 times when he talks about NAND based drives it reveals a total LACK of experience and he's making stuff up as he goes ..Writing to NAND flash memory requires the generation of high voltage, but reading requires low voltage. Before any NAND chip can write data into NAND flash memory it must internally generate a high voltage. This uses a “voltage pump” which takes time to charge up, and lower-end solid state storage does this much more slowly. Then, before reading, that high voltage must be dumped.
Steve distrusts SMART because he doesn't understand it. As you say, the one time that he tried to make use of SMART, he made a complete mess of things. His mistake was to apply intuitive logic to a counterintuitive case, specifically a Seagate drive. Essentially, SpinRite took a perfectly healthy drive and just kept spewing out thousands of bogus errors.Joep wrote:For example, SR hasn't got a clue about SMART stats as reported by Seagate drives.
