    Are there any recommended M.2 NVME/SATA docks? (Not Enclosures)

    I have had good luck with Sabrent branded adapters/docks over the years. That one doesn't seem to say anywhere that it supports M.2 sata drives just M.2 NVME.

    Battery float voltage for DC UPS?

    You need to separate the battery and charging system from the buck/boost except when the power goes out. This can be done with a diodes(low power) or a mosfet(high power) for near instantaneous switch over. Use a capacitor to smooth out the transition and the output after the buck/boost circuit...

    No sound on yamaha soundbar after power off tv

    ts the tv not the soundbar. All the soundbar does is play what comes out on the cable. It does not know which app is supplying the sound. Contact support for the tv and they might have a firmware update

    Do use a UPS or surge suppressor?

    yes many of them are fan on full all the time vs fan only when on battery or at least reduced speed when not on battery. That said they will operate at higher room temperatures without throwing an error. In an industrial setting the Eaton will be running after the others error out.

    Copyright Waiver? Design Release? Hold Harmless Agreement?

    Spam and using trademarks without permission are not a good business model and not a good way to meet new clients. If I bothered to engage it would be a c&d letter from an attorney demanding you take the pages off the net. I would then tell everyone I know not to do business with you. I...

    Intel 12/13th Gen latency?

    I have noticed the stutters he talks about on my 12400 dell which is 6P cores. It was worse when I got it and slightly better after a bios/microcode and driver update. I gave up chasing it down as its livable.

    Is mini USB flash drive just as reliable as regular length USB flash drive?

    usb ssd drive if possible would be best for that amount of writes. If not try the samsung bar plus or other more premium drive. I haven't used this drive but its cheap for what it is and the brand is ok. https://www.amazon.com/dp/B07RMYGZ1L better one...

    Hitachi SATA 60GB will not boot - suspect MBR damaged.

    Tried many times with about a 75% success rate. Put it back in the machine, boot from an os image to command prompt. The commands are easy to find. This has a much higher success rate than the drive in a usb adapter for me. I dont trust most 3rd party tools for this.

    Is mini USB flash drive just as reliable as regular length USB flash drive?

    They don't last long. A lot of the time the warranty is a bigger pain than the cost to just buy a new one. It depends on the size and $$. I think a lot of it is that some are not smart enough to slow down and cook themselves. I have had better luck using them for read a lot, write little tasks...

    Is mini USB flash drive just as reliable as regular length USB flash drive?

    Just assume they all suck and you wont be disappointed. I have had the best luck with the samsung bar models for regular read and writes. The better micro ones are ok for read a lot write little. They do not stand up to writes well. Use the right tool for the job. Sandisk has gone downhill.

    Windows file transfer killed a brand new SSD?

    I have had a lot of hardware fail in the first few months over the years. It is not uncommon even with the best brands. How they handle the rma separates the good companies from the bad.

    AMD Raid expand volume 3 x NVMe (7700x / x670e / RAIDExpert2)

    I never use recovery partitions so I often nuke them. It is always best to rebuild with an offline disk image backup or install media. There have been viruses that use the recovery partition install to reinfect the system.

    can I disable NVMe slot?

    Ok I just disconnected/removed drives for the install when I set up a similar system. You can then use the motherboards keyboard shortcut to pick a boot drive. I used grub on a usb drive to pick between the 4 oses. 2 windows versions, Debian and freebsd

    Intel Beast Lake: 10 performance cores and huge clocks

    Pretty much anything I do that needs anything beyond a few cores will peg them all for some amount of time. The E cores are a waste of space and $$$ that could have been used for more powerful cores in many use cases where a more powerful cpu is useful.

    Do use a UPS or surge suppressor?

    Cyperpower, sinewave which is better for your power supplies and I have used a ton of that unit with good results. Factory batteries are around $90 for the pair and new connector, Aftermarket $70ish for 2 batteries. The eaten probably uses the same aftermarket batteries.

    Do use a UPS or surge suppressor?

    Recently I had one with 5 year old batteries, no alerts. Power went off and they only held about 3 min under light load, enough to shut down. New it would have ran that load 25min+. Totally killed both batteries. Replaced the batteries and its fine. If its something critical I would replace the...
