Software Update: USB Drive Letter Manager 5.5.5

Version 5.5.5 of USB Drive Letter Manager has been released. This versatile program manages USB devices. For example, it is possible to assign drive letters only when a medium is inserted in the drive, which is useful for multicard readers. It can also be specified which drive letters may or may not be assigned, depending on the type of USB device, the size of the drive, the USB port used and the name of the volume. In addition, the application indicates by means of a speech bubble in the system bar which device or volume has been added to the system with which drive letter. More information can be found in this manual are being found. USB Drive Letter Manager is free for private and educational use, but companies and organizations are required to pay a fee. The following changes have been made in this release:

roll back:

• As before V5.4.9 USBDLM ignores the GPT attribute GPT_BASIC_DATA_ATTRIBUTE_NO_DRIVE_LETTER (Bit 63). Background: I had no idea where this attribute comes from. It turned out that this attribute is often not set intentionally, it is set by the Windows Disk Management when a drive letter is removed. This makes no difference on the computer where it is done but the drive will get no letter assigned on any other Windows computer by default too. When this behavior was implemented 20 years ago portable drives > 2 TB (which need GPT partitioning) where probably beyond imagination…

New:

• UsbDriveInfo can edit GPT partition attributes (right-click on a volume -> Edit -> GPT Partition Attributes)
