It's possible for it to be good. I have micro size USB flash drives where everything is inside the silver connector portion. The ribbon would only be for the LED.

A USB 3.0 cable is required for USB 3.0 speeds, but any USB cord will make a connection. Source 1: USB - Wikipedia SuperSpeed [USB 3.0] is supported only by USB 3.0 and newer interfaces, and requires a connector and cable with extra pins and wires, usually distinguishable by the blue inserts in connectors. Source 2: USB 3.0 Super Speeds - ...

No, this won't work. All data you are copying will need to be read by the computer from the source drive, before they are copied to the target drive. If anything, having two hard drives connected to the same USB hub might slow things down. If you have multiple devices connected to the hub, they have to share the bandwidth.

Yes, see USB protocols As I understand it, the USB spec defines a complex set of layered protocols and device profiles. For example, USB devices can conform to high-level templates like mass-storage, keyboard (or Human Interface Device, etc) and be managed by a generic device driver. Some USB devices can communicate at a lower level such that the OS low ...

A "USB 3.0 connection" requires a USB 3.0 cable. Some USB 3.0 devices can be connected and operated as a USB 2.0 device (at USB 2.0 speeds), using a USB 2.0 cable. However, speed is not the only issue. There are at least three important differences in cable construction between the two standards. Related to speed: The USB 3.0 cable has 9 internal ...

Unfortunately, it really depends on the specifics of the implementation of both the hub and device. Now, the vast majority of simple hubs don't really implement any sort of power control. They'll just connect the USB power lines directly to either their host or an external (regulated) power supply, which means you'd effectively be sharing the capacity of ...

The size of an internal-bay device is given by two figures: the "size", or form factor (usually 2.5", 3.5" or 5.25", but occasionally other values), and the height. Wikipedia has a list of hard disk drive form factors. According to that table a 3.5" HDD is 146 mm long by 101.6 mm wide, or just under 5 3/4 inches by exactly 4 inches, and may be either 19 or ...

Question: Is there a low-level USB communication protocol in action and what is it? Answer: Yes there is, the USB specification includes the USB protocol which defines the way the bus is used on a bit level. This would be the 'low-level' protocol that underlies the higher level protocols i.e. mass-storage, HID, etc. For specifics on how the USB protocol ...

This is what it actually looks like. We managed to get a hold of another USB stick (same type, same brand - owned by somebody else). Opened it up and it looked the exact same as the one shown in the pictures above.

This doesn’t make sense to me. Is there any reason for this? I noticed this as well when I upgraded my Mac Mini to a model with USB 3.0 ports on it; my older USB 2.0 drives would copy data noticeably faster. The logic I believe is not all USB 2.0 controllers are the same. The way I understand it, USB 2.0 speed is spec’ed to be a max speed; not a ...

USB are a host-driven protocol, not a peer-to-peer standard like firewire. Drives are just devices, they're not host to control or decide anything. Without the host they cannot even interact with the outside world. Assuming that you can connect the two drives like that, how can they know which files/folders you want to copy? Will they copy from which drive ...

The important part here is really that desktop hard drives used a 40 pin connector with a 4 pin molex power supply connector. Laptops used 44 pins - which includes power. A laptop PATA -> USB adaptor typically is self powered, or powered by a Y shaped USB connector with 2 USB A connectors for power A desktop PATA -> USB adaptor typically has its own power ...

Like nearly every other type of communication interface, USB is implemented as a protocol stack. The levels within this stack that are common to all or multiple types of devices are defined by the USB standards themselves, which both enables compatibility and prevents each device from doing redundant protocol design. Furthermore, each layer of the protocol ...

Well the pictures aren't 100% clear but it could be that all the electronics fit inside the USB plug. If the drive works ok in your computer this is the case. If you are adventurous you could try to open the metal casing of the USB plug. Warning this could destroy your drive (so backup data first).

Is there an effective method that is OS independent to prevent a USB from being written to? Not really unless you are using a device that explicitly uses a forensic write blocker/controller or something similar that blocks data writes on a controller level. Read and write permissions/restrictions on the vast majority of devices out there are ...

I've made a similar case mod few years ago. You can start with a USB bracket like this one: Note that it's simply a cable screwed to a bracket. Get one with port distance similar to this on original board. You may need to file the case a little bit so that ports aren't covered with plastic. Then simply unscrew the cable, glue it to the case and connect ...

A hub is just a way to share a connection to the computer when you don't have enough USB ports for all the devices you want to connect. Devices connected to the computer through a hub never talk to each other; the hub ensures that traffic between the computer and the connected devices goes to and from the right device as if each was connected to a USB port ...

My USB won't boot I am going to assume that this means an USB pen drive (and not a USB printer, USB scanner, USB network card....) This can have several reasons: The device is not bootable. The deivce is not bootable unless it was present early. The computer does not support booting from that type. The computer does not support booting from that ...

Is it possible to install Windows OS to plug and play storage devices? You can use Windows To Go. Windows To Go is a feature in Windows 8 Enterprise, Windows 10 Enterprise, and Windows 10 Education that allows them to boot and run from USB mass storage devices such as USB flash drives and external hard disk drives. It is a fully manageable corporate ...

You formatted it as FAT32 which will show as upper case in Windows Explorer. Format it as NTFS or ExFAT & it will show in Windows as mixed case. ExFat is more portable - most computers can read & write to it, natively [Mac & Windows, unix may need additional drivers]. NTFS is native to Windows, though other OSes may be able to read & ...

Is there an effective method—that is OS independent—to prevent a USB flash drive from being written to ? Yes, there are a few. You can use a forensic USB write blocker such as this one: From the product description: The compact USB WriteBlocker connects to USB storage devices and protects their contents during an investigation. To use, simply ...

USB Prober.app is not included in Xcode Search for iOUSBFamily and download the latest version on the developer page Installing the package is not recommended as it will overwrite your installed kernel extension, and can cause kernel panics at startup if the version downloaded does not match the OS. Instead, after downloading mount the downloaded ...

USB 3.0 jacks will work with older USB 2.0 cords, but at USB 2.0 speeds. The newer USB 3.0 connectors have more wires to carry the higher data rate.

Answers to questions like this depend on the so-called "attack model" that you want to be protected from. In other words, will the user actively try to overcome your protection? Or is the protection there just to warn the user, which you trust to be honest with respect to the read-only setting and not try to overcome it? In the second case, setting the ...

The second port is for additional power. Some PCs can't provide enough power on a single port. If your drive works on your PC with one port, you're okay. No difference in transmission speed or performance.

There are actually a set of related communication protocols which interact. At the lowest level, there is a protocol which describes how packets of bytes are sent over a serial connection. This is common for all USB devices (but different between USB2 and USB3). One of the first packets sent asks the device to describe itself. To prevent a chicken-and-egg ...

One would actually have to check both halves of the caseing, but just from looking at the picture this half of the case does not appear to be designed to hold more than it currently does. As such it at least appears unlikely that something has been taken out. If the person had their work on it it is probably a real USB.

If your USB drive is FAT formated, the maxmimum Size for a single file is limited to 4GB. If you need to copy bigger files you have to format it in NTFS.

Writing small amounts of data to a drive is slow, so system buffers writes to commit them all at once later. When the buffer contains enough data for an efficient write operation or when some process uses sync system call, the buffer is flushed to device. dd performs a low-level copy, ie. it reads data that is physically present on a device. It doesn't take ...

You can use a USB over CAT5 Extender. The link is one example. There are many available. You can then just add whatever length of CAT5 cable needed. I have used one with a USB webcam and it worked perfectly. Alternate link or search CAT5 USB extender and you will find something. AS noted, there are many models available
