Hi, I bought a used Dell constellation HDD from eBay. Here's the link for the listing.

It's supposed to be tested by them, but when I received it, it didn't spin up. I tried putting it inside my Lenovo ThinkCentre M900 Tiny, and also tried using an external SATA to USB adapter, but none of them work.

Now, it's a bit weird and different from the usual HDDs. It's 2.5 inch, but thicker than usual, 7200 RPM, and is supposed to be enterprise grade. So maybe I'm doing something wrong, and need a special adapter for it. Or it can be a faulty drive. I'm not sure. If anyone has experience with these drives, please let me know if I should be doing something different. Thanks.

Edit: I came to the conclusion that the drive is faulty. I contacted the seller, and was given a refund.

I have a Lenovo ThinkCentre M900 Tiny (10FL) which has been working fine. Recently, I had an HDD failure, and replaced it with an SSD. This time, I decided to go with ZFS (single drive, kinda pointless, but I get scrubbing). Every once in a while, I'm getting errors while scrubbing. It's always 1-2 read or write errors. And it never reappears if I clear the error and run another scrub.

The data isn't important, and it's backed up, so I'm not too worried about it. But, the symptoms make me think that it's an issue of the SATA port inside? Is it possible to replace the SATA port inside this device. I wasn't able to find anything like part number etc. online and it looks like I need to replace the whole board. Any help is appreciated.

I'm sorry but I'm frustrated by the blatant misuse of AI by my students and colleagues alike. It's so obvious when they don't understand what they've written.

Sure, playing chess needs intelligence, dedication, and good chess players are smarter than an average person. But it's waaaay exaggerated in movies. I'm a math researcher, and in any movie, my department will be full of chess geniuses. But in reality, only about 10% of them even play chess.

I'm trying to pull manual shots from my Breville Bambino, and it simply isn't working. I'm following the steps in the manual. (Press and hold the double-shot button for pre-infusion, then release it for the extraction to start, and then press again to stop.) The issue is, the machine stops midway, before I press the button. Seems like it's doing the pre-programmed double shot volume, and stopping after that. Does anyone has experience pulling manual shots from this machine? Should I contact Breville for a repair?

Edit: It fixed itself after performing a factory reset.

I currently have a zfs pool with mirrored vdevs, and it's working well. It only has HDDs. I was planning to add an SSD I have lying around as a Metadata Special Device, since I've read that it can improve performance by quite a bit. I've also read that if I do that, and if the special device dies, I lose my pool.

Now, I don't want to buy new SSD pairs for mirroring this one, so is there a way to ensure that the metadata is also stored on the HDD as usual, along with the SSD? I guess I want it to work like a cache for the metadata, and not the only place for it.
