How To Check USB Flash Drive Power Output

How to check a USB flash drive power output is fairly simple: the drive doesn’t output any power. That is the short answer.

What is really happening is the flash drive gives the host (the computer) instructions on the maximum power which should be sent to the flash drive.

So now that we understand a USB flash drive doesn’t put out power, but rather receives it, the next question becomes… how much power does the flash drive instruct it can receive?

When a USB flash drive is connected to a host computer there is something call a “device descriptor” which gives the host a long list of configuration settings. One of those device descriptors is the maximum power setting the device should receive. Now… it is 100% up to the host computer to respect that request, or not.

If you are having USB power disconnection issues it can be one of two things:

  1. The USB flash drive has too low of a power configuration setting
  2. The host is not respecting the device descriptor of the flash drive setting

99.9% of the time the host is respecting the device descriptor because the USB stock (code) to run the USB flash drives is typically well developed i.e. the USB driver is from Microsoft.

The more likely problem is the power setting of the device is set to low. If the power setting is set to low this means the host computer will monitor the power and since the USB is asking for more power than what is set in the descriptor the host computer disconnects the drive.

Below is a screen shot for the mass production tool used to make USB flash drives. As you can see the power settings available to configure the drive range from 100mA (milliaps) to 500mA. The maximum power limit for USB 2.0 is 500mA and thus should be the setting to make a USB flash drive. However, if the USB manufacturer messed up with an incorrect selection then a very good chance a 200mA flash drive is being disconnected all the time… and by no fault of the host computer!

usb flash drive power output, configure

So how do you find the power output of a flash drive? Or more accurately, what is the power consumption definition of the flash drive?

In short, there is no easy way to find this information in Windows. The easiest solution is download a 3rd party application and run the tool to see. The tool (USBDeview) is very small and runs directly as an exe file, no installation required.

Below are two screen shots.

The first screen shot is a USB flash drive set at 200mA. Clearly this device will run into disconnection issues

usb flash drive power output, to low

The second screen shot is a USB flash drive set at 500mA. This is the correct configuration of a USB flash drive for power output.

The above information is the easiest way to for USB flash drive power output for a thumb drive.

Solved: Can’t Mount IMG File in Windows 10

The first thing to understand is that image files are a messy business. There is plenty of cross-over information and functionality between image file extension types – it is easy to get confused!

Don’t be surprised if you can’t mount an .img file in Windows 10 with their default utility – it’s a common problem and this article will help.

Windows image mount utility

Windows, disc image file is corrupt

It is important to understand not all image files are the same. Heck, not all .img files are the same. Some basics: For the term “image files” you typically see .img files and .iso file extensions and they have similar functionality and conceptually accomplish the same goal. The goal is for an image file to hold digital content, in a single file, of a file system and a its set of data. If that sentence is confusing, then maybe think of an image file this way: a zip file (but without compression).

A very quick summary explaining the difference of .img and .iso image files. An optical disc holding data is configured differently than hard drive storage space. The optical disc has data written in a linear configuration and is a digital binary copy of the ISO 9660 standard or derivative UDF standard. The ISO file extension is a single file which contains all the digital information just described.

An .img file is a digital copy of the contents of a hard drive or flash drive. Technically you can have an .img of a CD or DVD as well, but most should associate the image of a disc as ISO. An .img file is a disk image which begins with a FAT sector which is used to identify the file system and files contained inside the image file. The image file of a disc (ISO) begins with a descriptor file which describes the layout of the disc.

That last sentence is important:

We Can Solve Apple’s Glucose Testing Issues – Just Do This

It’s been reported for over four years Apple is trying to solve the non-invasive way to test for blood glucose levels, yet continue to run into problems.

The problems have not been disclosed by Apple during the development process, but it is almost certain the reason is from inconsistent test readings. Meaning, Apple’s method or technique for reading a body glucose level is not consistent enough to submit for governmental approval.

Hey Apple! If you want to solve your glucose testing issues… listen up, here’s how:

It is well documented the level of glucose in the blood has a direct correlation to the viscosity or fluidity of the blood itself.

We feel the sensor technique from Apple is not accurate enough to determine the viscosity and therefore cannot get accurate glucose readings.

To us this makes sense because whatever sensor the Apple watch is using, is trying to determine levels through a part of skin which is too thick. The wrist.

Here is your hot tip Apple (@AppleHCG @tim_cook):

Forget using the Apple watch as your source for testing. What Apple needs to create is a mouth piece that communicates with the Apple watch and scan the lingual frenulum skin for opacity which in turn indicates viscosity of the blood. The lingual frenulum is the thinnest piece of skin on the human body which gives you the ability to more clearly scan for blood viscosity by determining the level of opaqueness of blood circulating through the lingual frenulum.

A mouth piece would need to be developed to sit under the tongue with a sensor pointed towards the lingual frenulum which would scan the blood circulation or flow and based on color feedback it can be determined the level of sugar in the blood stream at that time.

The “under tongue” mouth piece would be used only when a reading is required by the user. In our estimates the reading would last no longer than 5 seconds.

To get the reading, the mouth piece would be designed to read from the left and right side of the lingual frenulum to determine the opaqueness of the blood. The heavier the viscosity the darker or dense the blood is and therefore more opaque. Blood is lighter when the glucose level is lower and less opaque. Blood is darker when the glucose level is higher.

The “under tongue” mouth piece would communicate wirelessly to the Apple watch to report the reading.

It goes without saying, the above solution is not a finished product. Development and testing of the mouth guard would need to be designed by the Apple HealthCare team. But this hot tip points you in the right direction.

If someone at Apple reads this article, I hope they have enough moral fiber and respect of OUR idea to reach out and contact us. gmo (at) getub.info

Review: Rufus The Big Misconception With ISO Files

If anyone searches for “burn ISO to USB” they will get pages and pages of Rufus links. However, there is a big misconception with Rufus… it doesn’t create USB CD-ROM drives!

The only thing Rufus does is take a bootable ISO file and write the data to a USB stick. Basically Rufus will extra the data on an ISO file and write it to the flash drive. You can do the same thing with WinRAR.

There is nothing magical about Rufus when it comes to “making a CD” because Rufus doesn’t make a “CD.”

If you need to make a USB CD-ROM flash drive the best solution found so far, is the Disc License drive. The Disc License drive is a blank USB CD-ROM flash drive. Using their Drive Wizard software (free), easily write ISO files to USB. The resultant drive will be a USB CD-ROM flash drive.

Before we get into Disc License technology, we do need to clear up some points about WinRAR and Rufus software. WinRAR will extract all the files contained in an ISO file and write them to your USB flash drive; however, if the ISO is bootable, WinRAR won’t write the boot code. This is where Rufus does shine. The Rufus software will write all the files contained in an ISO file along with the boot code to make your device bootable. With that said, there is a clear advantage for using Rufus over WinRAR.

Does Rufus burn any ISO file to USB? NO.

Does Rufus make your USB flash drive read-only, like a CD? NO.

If the ISO file isn’t bootable, there isn’t much [more] Rufus can offer. A non-bootable image will display an error message saying “This image is either non-bootable, or it uses a boot or compression method that is not supported by Rufus.”

rufus does not support iso file

Rufus is truly designed for one thing:

DIY USB Power Hub Station

Using very simple and inexpensive items, create a USB power hub station for all gadgets like headphones, chargers, GPS units, GoPro camera’s and more.

In addition to a very organized solution, the DIY USB power hub station is out of the way, yet easily accessible. No more taking up valuable kitchen counter space with cluttered gadgets and a birds nest of cables.

The solution is ultra-easy. For the DIY USB power hub station all you need is a shoe rack for the closet, a USB hub and your cables.

In less than 10 minutes you can be organized, powered and out of sight. This DIY project was less than $35 dollars.

First, grab a hanging shoe rack from Amazon. I found this 10 slot shoe rack for $13.

Next, grab a USB hub that only runs power (less expensive) and I found a matching 10 socket version for my 10 slot shoe rack for $20.

The only thing left to possibly buy are cables. However, you probably already have the powering USB cables required for your devices. I do think getting cables that have a combo Apple Lightening cable and microUSB cable allow things to be a bit more flexible when connecting various devices.

Here is a set of two cables with three different connectors (Lightening, USB-C and microUSB) for $6.00 (each) $13 total.

Once your items arrive the assembly is literally two minutes. There is a good chance it will take longer to clean out your closet than assemble the DIY USB power hub station.

The best location would be in the closet under your stairs. This is true because the space most likely has a power outlet.

  • Step 1 – Cut a small piece of fabric in the back of each shoe rack slot
  • Step 2 – Place USB powered hub in the bottom shoe rack slot
  • Step 3 – Lay out the shoe rack and thread each power cable from the USB hub to each shoe rack slot
  • Step 4 – Place devices in shoe rack slots and connect
  • Step 5 – Hang USB power hub charging station in your closet

How To: Check for Bad Sectors on USB Flash Drive

This how to tutorial describes a simple way to check for bad sectors on a USB flash drive. The instructions below will also fix any bad sectors, if possible, during the scanning process.

A bad sector on a flash drive is a portion of memory on the flash drive which cannot be accessed, written to, or read from and therefore cannot be used. A bad sector on a flash drive sounds easy enough to diagnose, but it’s important to know there are two types of bad sectors: hard and soft.

Physical damage to a USB flash drive will create a hard bad sector. A hard bad sector cannot be repaired or fixed and is typically induced from physical abuse. A good example: leaving a flash drive in your pocket and it went through the wash, or the device was dropped and hit the ground is such a way, physical damage happened to the memory.

A soft bad sector on a flash drive are memory logic problems. A soft bad sector can occur from a software or data error during the write process. In lower quality flash drives, it is possible the incorrect firmware was written into the USB controller ROM and thus creates instability via soft bad sectors.

Bad sectors cannot be repaired; however soft bad sectors can be repaired.

The soft bad sectors can be fixed by using the CHKDSK utility in the Windows operating system. This same utility will also flag any hard bad sectors not to be used again, and of course not repaired.

Some signs of a bad sector on a flash drive include:

  • Cannot read a file on the flash drive
  • A file location is no longer available
  • Unable to format the USB flash drive
  • A disk read error occurs during operation

In our opinion, run the check disk one time to see if your issue is resolved, but if subsequent scans are required, we recommend discarding the flash drive to avoid further issues.

Running the chkdsk scan is really easy:

Insert flash drive to computer

Using Windows Explorer navigate to the drive letter

In the Explorer window type cmd and press enter

access usb flash drive cmd command

Once inside the command line utility type chkdsk d: /f /r /x and click Enter. NOTE: *The letter d represents the drive letter of the flash drive.

chkdsk commands for usb flash drive

  • The /f parameter tells CHKDSK to fix any errors it finds.
  • The /r parameter tells Windows to repair/restore bad sectors (if possible).
  • The /x parameter unmounts any “handles” to the drive or said another way, this step will not allow any other resource to access the flash drive during the scan.

Industrial Control System USB Flash Drive Designed For ICS Security

Industrial Control System USB Flash Drive Designed For ICS Security

The fourth industrial revolution or “Industry 4.0” is a term used to categorize today’s trend with industrial control systems (ICS) and how these machines interact with each other and humans.

The fourth era of “industry” combines hardware, software and biology and emphasizes the advancements in communication and connectivity. When the term IoT (Internet of Things) is used, this is the type of example that would apply. Industrial Control System USB Flash Drives designed for ICS security are critical to industrial systems and how they are controlled by their owners. The key when a USB flash drive is introduced into a control system, is security. Without security, one could lose control of the industrial system and ultimately introduce risks into a population or region.

Before we look closer at Industry 4.0 and data storage, let us provide a short summary of the first three phases of the industrial revolution.

First Industrial Revolution

The first industrial revolution was marked by a transition from hand production methods to machines through the use of steam power and water power. The integration of these new technologies took a long time, and spans a period between 1760 and 1840 for Europe and the United States. The first phase had the greatest impact on virtual industrial channels such as textile manufacturing, iron production, agriculture and mining (in general).

Second Industrial Revolution

The Second Industrial Revolution, also known as the Technological Revolution, is the period between

How To: Add USB Flash Drive to Roku TV Getting Pause and Rewind Features

It is not difficult to get some premium functionality from Roku TV like pause and rewind by simply adding a USB flash drive to your setup

You will need to configure the Roku TV and the flash drive to work together, but it’s not hard to do.

To get close to 90 minutes of pause or rewind time you will want to use a 16GB or larger flash drive. So using something small like a 2GB or 4GB USB drive, probably isn’t worth the effort.

The other caveat is that the pause function is only available on the live TV input, limiting you to whatever’s coming over your antenna or cable connection.

So if the above sounds like something worth trying, let us show you the way:

What you’ll need:

  • Roku Smart TV (not the dongle or box). Said another way, a Smart TV with the Roku app.
  • Live TV input (usually either antenna or cable)
  • Roku TV remote control (standard with Roku purchase)
  • A 16GB or larger flash drive. Can be either USB 2.0 or USB 3.0

Once you’ve selected your flash drive be sure nothing is on the USB stick. This process will format the drive and remove any files you have on the drive.

Getting Started

Locate a USB port on your Smart TV. Any port will work. These will be found on the back side of your Smart TV. Connect the flash drive to a USB port.

Going to your Roku home screen and move the cursor until you are highlighting the LIVE TV option. This will be a tile on the home screen.

Don’t click LIVE TV, but rather get into the Options menu of Roku. You can either click the Gear button on the Roku remote, or you can press the Home button on the remote five times.

roku tv remote with gear, setting, button

In the Options menu select the “Set up Live TV Pause” and follow the on-screen instructions. Part of those instructions will include formatting a USB flash drive so Roku can sync with the flash memory for pause and rewind features.

Roku software will ask you to confirm the formatting process via a pin. This is only to make sure you think before you format because once you format the drive, any old data on the USB stick will be gone!

roku tv format usb flash drive

Done

Once live TV pause is enabled, you will be able to pause live television using the play/pause button on the Roku remote. You can also rewind up to (about) 90 minutes of live TV. This gives you plenty of time to have a nice family dinner while the Roku is on pause… then come back to finish the show.

Hold USB Flash Drive In DVD Case – Brilliant Solution – Inexpensive

Hold USB Flash Drive In DVD Case

This is a brilliant solution which after viewing the video you will say: “this should have come out years ago!”

This is the least expensive, yet most secure way to hold a USB flash drive in a DVD case.

The era of CD and DVD is coming to a close with USB flash drives taking its place. Yet many CD and DVD duplication facilities have shelves and shelves of DVD jewel cases which they need to put to good use. This DVD-to-USB-Insert card is the quick, easy and cheap solution. The insert allows users to keep their DVD case and related jewel case artwork to remain the same, but now secure a USB flash drive inside the DVD case, rather than an optical disc.

So many businesses enjoy the DVD case because the DVD case is a great storage box. The case is a good size with a thick spin to print what the contents in the DVD case are.

Continue this same “library” methodology with the DVD-to-USB-Insert card.

In case you can’t see, or didn’t see, the video posted above the solution will hold two USB flash drives in a DVD case. The DVD-to-USB-Insert is a thick 0.65mm clear plastic which is the same diameter as a DVD. However, the clear plastic has two rectangles which are inverted to hold just about any sized USB flash drive. This solution will fit two USB flash drives into a single DVD case. The two rectangles are the same size and as said, will fit darn nearly all USB sticks with a size that is 3″ long by 3/4″ wide and a depth of 3/8″ ( for you metric folks, that is 76mm long, 21mm wide and 9.5mm deep).

The clear plastic has a hole in the center the same size as a DVD disc and will snap into the “holder” of the DVD case. Using any DVD case on the market you can easily hold a USB flash drive inside a DVD case. The video shows how secure the USB flash drive is when inside the DVD case. The flash drive will not fall out during shipping or transit.

To be clear, the DVD-to-USB-Insert is only the clear plastic that holds the USB flash drive using the nipple snap that holds the DVD. The DVD case itself is not sold with this solution because the assumption is you (the user) already have stock or inventory of the DVD case itself.

This solution to hold a USB flash drive in a DVD case does not infringe on any patents from other manufacturers who use alternate solutions to secure a flash drive inside a DVD type case.
