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.
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:

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 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 is truly designed for one thing:
Batocera.linux is an open-source and completely free retro-gaming distribution that can be copied to a USB stick or an SD card with the aim of turning any computer/nano computer into a gaming console during a game or permanently. Batocera.linux does not require any modification on your computer. Note that you must own the games you play in order to comply with the law.
The Batocera firmware lets you flash a lightweight, emulation-focused operating system onto any flash drive, hard drive, or SD card. So what if we flashed it onto a flash drive, loaded it all up, and then used that as a portable gaming “system” that could be plugged into any Windows PC? That’s what we’re going to explore in this video.
CD and DVD optical duplicators have been popular for years; however, with the disc drive no longer sold in computers, the only device left for moving files around are USB flash drives – well, most common device at least. With that in mind, let us take a look review a USB flash drive duplicator and wanted and provide observations.
So what is the speed of burning a DVD compared to copying to a USB flash drive? With a 16X DVD recorder it will take about 6-7 minutes to burn an entire disc, which is 4.7GBs. A common size DVD duplicator is seven drive system which means 7 copies every 7 minutes. However, today’s file sizes are getting larger and a data load can easily be over 5GBs. A dual layer DVD is 8.5GBs and would take about 27 minutes.
The USB duplicator in this review is a sixtenn target USB 3.0 duplicator manufactured by Nexcopy. This model was selected because it was the most popular in search results, and honestly – looks best for an office setting. This system will make sixteen copies at 1GB under a minute; which translates to 16 copies in less than five minutes. The dual-layer DVD mentioned above would be 9 minutes to make 16 copies. Clearly a USB duplicator is more efficient than a DVD duplicator.
Nexcopy’s model in today’s review is the USB160PC. This is a Windows computer based software and hardware solution which runs on Windows 7 or Windows 10. The copy speeds are the same as designated standalone systems. Below is a picture of the PC based system and the standalone system, both about the same port numbering (16).
The USB160PC uses software and provides six copy modes which a company can chose which copy method is best for their needs. Copy modes are:
- File Copy
- Copy Add
- Device Copy – Data Only
- Device Copy – Full Media
- IMG Copy
- Unique Data Streaming
We will cover the copy modes a bit later in the review.
The Drive Manager software by Nexcopy, has a data extraction feature giving the user the ability to extract data off the drive and make a data dump to a location on the host PC.
The PC based USB duplicator is fast and flexible to work with and provides excellent user feedback during the duplication process. The GUI (Graphical User Interface) ties in the obvious information such as USB flash drive total size, bytes used, percentage done during duplication and pass/fail response. Nexcopy uses their own Drive Manager software (trademarked) and provides lifetime software support and updates for free.
The GUI does an excellent job of identifying the USB device shown in the software with the USB socket on the duplicator. This is one problem with any home-grown duplication system, like connecting flash drives to a USB hub – the only way to identify a drive is by disconnecting it until you’ve found the one in question. The USB160PC gives you the tools to quickly identify each USB drive connected.
The bonus information from Drive Manager is the second tab of the GUI. This page shows the device serial number, the VID (Vendor ID) the PID (Product ID) and device descriptor information. The tech folks will appreciate this feature.
For this USB duplicator review we weighed the duplicator box and it came in just under 5 pounds – so portable! Two LED for feedback along with the GUI software. Blue LED shows power to the socket and green LED displays activity of the device (will blink when reading or writing data). The GUI will provide performance feedback and status about the copy job and process. The power supply is auto-detecting and will automatically work in a 110v or 230v environment, no need to make a manual power setting switch with the physical box. The USB duplicator has a 5v fan on the back side to provide air flow for cooling; although we didn’t experience any heat during testing and operation.
The power supply inside is a 150watt MeanWell brand power block, which is a brand used by medical companies so power will never be an issue. This also means the 150watt power supply can support 16 USB hard drives.
