Plug the two USB drives into your computer and make sure they can be detected. Open the Windows Explorer, select the files on the old USB drive, right-click it and select Copy. Then, Paste them to another USB drive. This will work well.
The maximum packet length for full-speed USB communication is 64 bytes. So the data will be transferred in chunks of 64 bytes and needs to be reassembled on the other end. USB CDC is based on bulk transfer endpoints and implements a data stream (also known as pipe), not a message stream.
Bulk Transfers are used for data which are not of the type Control, Interrupt, or Isochronous. Reliable exchange of data is ensured at the hardware level using error detection. Data are transferred in the same manner as in Interrupt Transfers, but have no defined polling rate.
If you are using a regular cable (max length of 5 meters for 2.0 and max length of 3 meters for 3.0/3.1) with an active cable, then the maximum length for USB 2.0 is 25 meters (about 82 feet) and the maximum recommended length for USB 3.0/3.1 is 15 meters (about 49 feet).
Each USB transfer is one packet, which can be up to 64 bytes if using bulk type. If you want to send more than 64 bytes, you have to use multiple packets.
Maximum packet size of a bulk endpoint depends on the bus speed of the device. For full speed, high speed, and SuperSpeed; the maximum packet sizes are 64, 512, and 1024 bytes respectively.
Bulk Transfers. Bulk Transfers are used for data which are not of the type Control, Interrupt, or Isochronous. Reliable exchange of data is ensured at the hardware level using error detection. Data are transferred in the same manner as in Interrupt Transfers, but have no defined polling rate.
To format a USB storage drive in Windows, connect it via a USB port and follow these steps: Open your File Explorer. From the menu, select "Format." Leave the settings at their defaults or select specific values as needed. Click "Start." A confirmation message will appear when formatting is complete.
MSC is a protocol that enables the transfer of information between a USB device and a host. The information being transferred is anything that can be stored electronically, such as executable programs, source code, documents, images, configuration data, or other text or numeric data.
USB Full speed has a speed of 12 MBit/second = 1,5 MByte/s. But within these 12 MBit also a lot of extra data is transmitted which is not payload, like , endpoint address, CRC5, CRC16, Acknowledge, SOF + EOF packets, etc.. Additionally the bus manager reserves 10% of a frame for Control Transfers.
