To no avail, I have done a ton of reading here and there over the last couple of years on how to get TRIM to work for SATA SSDs in a RAID1 configuration.  I believe TRIM would work fine if I switched to RAID0, but that's not what I want to do.

I'm aware of the pros and cons of simply foregoing RAID with SSDs.  I might go that route and I don't need further convincing.  To skip RAID1, I simply need to be convinced that I won't be able to get TRIM working.

I'm also aware that TRIM isn't completely necessary; I just need to expect that the drives won't perform quite as well over time and won't last as long, kind of defeating the purpose of fault tolerance.  Interestingly, the 1TB Samsung 840 EVO drives I'm currently using have been powered on for over 7 years and each have over 53TB of data written to them.  I guess the age of the drives is why I'm getting more anxious to find conclusive answers.

About a year ago, when I decided to be done with Win7, I destroyed the array, erased and TRIMed the drives, re-created the array, and installed Windows 10.  The temporary performance boost after a TRIM was immediately apparent.

I could accept that TRIM with RAID1 is impossible if not for the last statement at the URL below, which practically proves that it can be done with the right motherboard and possibly with the requirement of using a Xeon processor.

I'm looking to upgrade about 20 computers at our business and I want a good deal.  The software the computers will be running are office 365 and a Remote desktop connection to a server that hosts our accounting software.  That is all, other than a network printer they will print to.  I found this computer on Newegg.com and was wondering if it would be enough specs for the task:  Lenovo ThinkCentre M92 Intel Quad-Core i5 (3.2GHz), 16GB RAM, 240GB SSD, DVD, Windows 10 Pro, WiFi, Keyboard and Mouse

The price is $244

I am a little confused why this machine costs so little.  Is it because it is a quar-core i5 (3.2) and manufactures are well past that?

Moore's Law and IBM's Summit

Does anybody have a recent chart  that would confirm or refute Moore's Law which says that "the number of transistors in a dense integrated circuit doubles about every two years."

Is it faster? Has that rate increased? Held steady? Or is it in decline?

And I wonder about is there were some similar measure of processing power from a super-computer that would help us see the growth in processing power over time?

Thanks.

I'm running a server with ESXI 6.0 I'm having issues with the box - it's slow and my virtual servers are freezing.  I went to hardware and looked at health and saw the following - see attached.  How can I verify this is the issue.  I have ssh enabled but I don't know how to see if I'm actually having hardware issues.a.pngb.png

We can not get an old Dell system to bootup. Some on screen message saying press the power button or mouse or any key on the keyboard. Nothing.
We need to know if this system is 32 bit or 64 bit.

It's Windows XP Pro

I hot-swapped a drive in a Supermicro chassis (D-1541) and the drive light next to it is blinking yellow now and inaccessible to vSphere.  How do I get that to go back to normal?

The user suddenly got a message saying that the power adapter for their Inspiron 15-3565 Laptop  couldn't charge their computer.
Dell Charging Error
I had them shut down the Laptop.  When it came back on, there was no message anymore.  HOWEVER, yesterday they shut down and that didn't help.

Is the problem with the adapter, the motherboard, Windows 10?

How do I proceed?   Replacement 3rd party adapters are cheap enough, if that's the problem.

Thanks.

Hardware ECC Recovered = 1
Anyone else having issues with Seagate HDDs?  The computers on day 1 will have terrible performance ups and downs.  File corruption and random errors running any program.  Working with Dell to get to the bottom of this, we found that the Hardware ECC recovered current will at 1 while the performance issues exist, and rise to 40-60 when working normally.  Upon cloning to another brand of HDD and running CHKDSK, it will result in a proper working system with no performance problems.  We have been studying this for months, and have seen this in 100% of Seagate drives installed since April 2019.

I need to purchase 30-50 18650 Li-ion batteries.  There is such an enormous range of specifications for this cell that it is mind boggling. I see specs from 1000 mAh up to 6000 mAh. I find that difficult to believe. I am looking for longevity and quality more than capacity. These will be used in a transmitter sending telemetry data. The transmitter will be active for 4 minutes at a time drawing 1.0 amps. Has any Expert seen a brand comparison done that is not manufacturer sponsored rating several different brands? It would be great to see some impartial ratings. I do not want a cell that is very low for obvious reasons nor do I want to push the limit of capacity and sacrifice longevity. Any suggestions would be welcomed. I prefer to buy this type of item either from Amazon or DigiKey.

CompTIA Cloud+

The CompTIA Cloud+ Basic training course will teach you about cloud concepts and models, data storage, networking, and network infrastructure.

I can only use two of the three monitors at a time.

This is a Win7 Pro desktop PC with a GEForce 210 video card, with a VGA, HDMI, and DVI connector.  The primary monitor is connected to the HDMI port.   I have a DVI-VGA converter plugged into the DVI port.  If I connect all three monitors, one of the non-primary monitors will be black.  The 3rd monitor does appear on the Windows Screen resolution setup screen, but its icon is darker grey, and the Resolution and Orientation fields are greyed out.  The Multiple displays field says Disconnect this display, and no matter what I change it to from the dropdown, it ignores me and goes back to Disconnect this display.  

The Nvidia control panel only sees two monitors at a time, i.e. never three like Windows does, but if I disconnect one of the side monitors, then the Nvidia control panel "sees" the other side monitors and displays its model name correctly.  Note that I just now downloaded the latest driver for the GEForce 210 and rebooted.

Is this card incapable of running three monitors, or am I doing something wrong?  TIA

Hello and Good Morning Everyone,

            Throughout the past, I have networked out to online companies whenever I wanted a coffee cup made or a  t-shirt customized for someone special on their birthday or as a special gift for Christmas,  Recently, I have been wondering how nice it would be if I could simply do it myself from home which brings me to this upcoming question.  Can a kit complete with the needed hardware and software be purchased which would allow a novice individual like me custom design t-shirts, caps, cups, plates, and so forth from home?  If so, could someone perhaps provide an online purchase link or links so I can review the components of such a comprehensive kit?

              Thanks so much in advance for any attention given to this question.  I look forward to reviewing any and all feedback given in reply to this question.

              George

I run across business customers who want to use multiple monitors, but their computers don't offer enough video ports and/or the wrong types.  Typically they are on Win10 or Win7.

I can install a video card, or I can connect multiple USB adapters, such as USB- to-HDMI.  Keeping in mind that this is just for small office use, I need guidance as to whether one of these methods is the definite "best choice"--and why.  TIA

The customer wants to use three new monitors for the office computer, for typical office apps.  All it has on the motherboard is one VGA and one DisplayPort, so I wanted to get a video card that would support all three monitors using the HDMI and/or DP ports on the monitors--which is all they have, being large and new.  But every reasonably priced video card I look at has VGA, DP, and DVI--and of course VGA and DVI do me no good in this case.

Is there such a thing as a reasonably priced video card that has all DP and/or HDMI outputs?  Low profile would be even better.  Again, I'm not looking for hi-res graphics or gaming features.  Rather, I'm just trying to get access to three "modern" video ports for this PC.  

Or, should I buy three USB HDMI video adapter dongles--and expect that to look good and for Windows 7 to manage all three screens properly?  TIA

Lenovo T430s. I've noticed it is rather warm under the top left of the computer. Even though I am using it in front of a fan. It's cooled down some as the fan blows. Actually it is the top left side more than the bottom and also the top left rear. What parts are inside the top left of the laptop? Thanks

Hello and Good Afternoon Everyone,

          I am wondering if it is possible to locate and purchase a handheld instrument that can use laser light to access measurements like height, width, and depth and transmit this information digitally back to its display.  I am not sure if such a device exists commercially, but, I know if it does, someone on this forum would definitely know for sure.  

          Any shared thoughts or possible leads regarding this interest will be greatly appreciated.

           Thank you

Hi,

I need to know the difference between
-  HPE 128GB (1x128GB) Octal Rank x4 DDR4-2933 CAS-24-21-21 Load Reduced 3DS Smart Memory Kit
And
- HPE 128GB (1x128GB) Octal Rank x4 DDR4-2666 CAS-22-19-19 3DS Load Reduced Memory Kit

I mean which one has better performance

Thanks

Distributed processing, space telescopes and super-computer speeds

I read that IBM sold a super-computer called Summit in June 2018 that could perform 200 Trillion transactions per second.

Curious...

How many average Windows laptops are need to rival that kind of power?

And if that average Windows laptop is used in a business environment, what kind of hardware utilization is there to:
1) Run Windows
2) Perform ordinary office uses, like email, word processing, running a virtual terminal?

Secondly, what can you tell me about the processing power of a distributed model where thousands of PC's perform calculations when it detects idle time?

There is a famous space telescope which does this. Please remind me of the name of that system.

Thanks

Hi,

Strange thing today.  My computer monitor messed up and just replaced it with a temp monitor.  All works fine but Netflix won't.  It gives error:

Error code: U7361-1255-C00D7159

Open in new window


When searching the error, I have:

Netflix Error H7361-1255-C00D7159
If you experience the error code H7361-1255-C00D7159 on your computer, it's typically caused by using an unsupported video output method, such as a Wireless Display Adapter. Netflix is only compatible with video output methods that support content protection (DRM). To immediately stream on your computer, follow the troubleshooting steps below. To successfully watch Netflix through a video output method, contact your device manufacturer to learn which devices support DRM protection.

The strange thing is that I only change the monitor.  If I move the Netflix apps to the notebook (my computer is a notebook with an external monitor connected), it works, so it seems it's the monitor.

The setup is:
- the notebook has an USB connector
- in that connector is a Insignia USB to Hdmi and an USB cable connected to the monitor.  I had this same setup with my old monitor.

Please let me know whats going on or is it a configuration.

Why Diversity in Tech Matters

Kesha Williams, certified professional and software developer, explores the imbalance of diversity in the world of technology -- especially when it comes to hiring women. She showcases ways she's making a difference through the Colors of STEM program.

How-to identify, diagnose and prove that the power surges that were caused by an affiliate of the power company destroyed my electronics. All my electonics have very strange behaviors. They are all damaged. As i'm sure all the other electical devices of all 150+ homes that were also plugged in are damaged as well. (Mobile Home Park)  I would be needing to be able to prove this.

So my question is: I'm attempting to prove this occurred, and I'm looking for the proper authorities to take this issue to. Where would I go about that?

NXP LPC11E68JBD48E Microcontroller I2C1 is Master.   I2C1 is in Master Transmitter Mode.
I2C1 peripheral is in chapter 13.  http://www.mouser.com/ds/2/302/UM10732-315822.pdf
NXP PCAL6416A I2C 16-bit I/O Expander is Slave. https://www.nxp.com/docs/en/data-sheet/PCAL6416A.pdf.

Master reads one byte from slave port 0.  On one board all Eight bits are logic 1's as expected.  On the other board Seven bits are logic 1's as expected
but bit 2 is logic 0.  The input pin connected to bit 2 is pulled up to 3.3V but it's logic 0 on I2C data bus.  Why?

                              D7 D6 D5 D4 D3 D2 D1 D0
Expected              1    1    1    1    1    1   1    1
One board           1    1    1    1    1    1   1    1
Another board    1    1    1    1    1    0   1    1

Explanation/Questions on attached scope screenshots:  Master sends slave address 0100 001(A6-A0), followed by write bit(logic 0).  Slave responds with ACK(logic 0).
Then, master send command byte 0x00(read byte from Input port 0).
Master sends start bit, followed by slave address, followed by read bit(logic 1).  Slave sends ACK.
On one board, slave send 0xFF as expected.  On other board, slave sends 0xFB, not expected. Master follow with a NAK.  Slave pulls data bus low before the stop
condition?  Why slave pulls data bus low?

The primary question is why is bit 2 logic 0 on the I2C bus when it's pulled up to 3.3V ?

Are we setting the I2C device properly?
INT pin(active low) is floating.

Guys,
i have seen the incoming cables from outside connected to the mccb device here  directly from the meter panel and its rated under 63a, my question here is I  don't know how much  amp it comes from the  service line which only stated 415v incoming. so this mccb 63a  user to convert the volt from outside becomes 63a or to only allow my house getting  accces with 63a ?

Hello and Good Morning Everyone,

         I am wondering if it is possible for new and unused external USB flash drives to become defective or bad over time.  The reason I ask is because I am considering buying a pack of external USB flash drives for quick and convenient data backup and restore purposes.   Realizing there might be some new ones which might not get used for several months or even a year, I do not want to take a chance on them going bad simply because of non-use.

         Any thoughts shared to this question will be appreciated.

         Thank you

Secure Wipe SSD Drive

I've seen a lot of things on the web and searched here. I just want something succinct and usable.

I've stored up about three dozen SSD's and need to securely wipe them.

Does this plan sound good?  Additions?

Take one of the drives, initialize and format it
Activate Bitlocker on the drive
Fill up drive with files from \windows\system32\*.exe
Dupe this drive over the remaining drives of that same size to overwrite all sectors (hopefully)
          (This way individual sectors won't still have any data)
Use Parted Magic or Crucial's SSD software Erase Drive to low level initialize the disk

We are following instructions to burn to disc one (1) mp4 video. The first program did create the audio_ts and video_ts folders
In the image you see a mention of a file system. It also mentions using your own favorite burning software. Efforts to burn these two files (audio_ts and video_ts has failed.
What is this file system?
What other programs can you suggest. It's one video to play before a group of people so we need the video to play on a table top player and I try not to pay for a program since it's only one video needed. Thanks.
w
The burner recommended along side the above program that created the file structure, was to locate the folders and move them to another folder. Here they are and the chosen burner is getting errors when trying to just add the folders to the burning program.
