  • New: "PortableBaseLayer" system volume is ignored
  • New: UsbDriveInfo shows hidden disks

New in USB Drive Letter Manager 5.5.9 (Aug 10, 2023)

  • Bugfix: Some graphical glitches in UsbDriveInfo on high DPI scalings

New in USB Drive Letter Manager 5.5.8 (Jul 10, 2023)

  • New: New function "uninstall a USB device" for the command interface
  • New: BalloonTips and UsbDriveInfo look better on high DPI scale
  • Bugfix: Criteria VolumeLabel did not work in [OnArrival] for manually unlocked Bitlocker volumes

New in USB Drive Letter Manager 5.5.7.90 Beta (Apr 10, 2023)

  • New: New function "uninstall a USB device" for the command interface.
  • Bugfix: Criteria VolumeLabel did not work in [OnArrival] for manually unlocked Bitlocker volumes.

New in USB Drive Letter Manager 5.5.7 (Jan 22, 2023)

  • Bugfix: USBDLM may crash when arrival and removal events are triggered in fast succession for the same drive
  • Bugfix: UsbDriveInfo showed a messagebox after writing a report by command-line
  • Bugfix: UsbDriveInfo showed "Error path not found" on Tools -> Compact VHD

New in USB Drive Letter Manager 5.5.6 (Nov 14, 2022)

  • Bugfix: USB High-Speed devices reporting a USB version 2.1 no more assumed being SuperSpeed capable
  • New: The MSIs creating an entry in "Programs and Features" aka "Add/Remove Programs"

New in USB Drive Letter Manager 5.5.5 (Sep 4, 2022)

  • Rollback: 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 behaviour 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)

New in USB Drive Letter Manager 5.5.4 (Aug 1, 2022)

  • Bugfix: USBDLM since V5.5.2 removed the drive letter of GPT partitions with the attribute in bit 63 set (GPT_BASIC_DATA_ATTRIBUTE_NO_DRIVE_LETTER, diskpart calls it "nodefaultdriveletter"). Now USBDLM just does not touch the drive letter of such volumes. As before you can let USBDLM ignore the attribute by IgnoreNoDefaultDriveLetterAttribute=1 in section [Settings]

New in USB Drive Letter Manager 5.5.3 (Jul 27, 2022)

  • Bugfix: USBDLM.msi V5.5.2.x failed to update any older installed version

  • Conclusion: I should release Beta versions again

New in USB Drive Letter Manager 5.5.2 (Jul 25, 2022)

  • New: USBDLM removes the drive letter of Windows "System Reserved" partitions on MBR drives (which get a drive letter assigned when a system drive is put into a USB case)

  • Bugfix: Under Windows 8 and 10 OnArrival for Bitlocker drives was executed immediately instead after unlock. Now twice, see Bitlocker.
