I'll have to attempt to get some support from Lenovo meanwhile, I've set up a UAC elevated desktop shortcut to C:\Windows\System32\cmd.exe /K C:\Windows\System32\sc.exe stop "TVT Backup Service" So, the provisional answer appears to be that this problem is nothing to do with handles to Transactional NTFS files blocking the USB removal, but rather the handles of the Lenovo backup process blocking the removal. I also ensure that the external disk cannot have contents indexed by removing that option on the disk's property sheet. I have always disabled the shadow storage on external USB drives by using the "system Protection" settings sheet in System Settings. That reference the external USB harddisk:īut stopping the service releases these handles, and then the external USB can be removed using the usual notification area icon. This rrservice.exe service process uses many handles with "Harddisk" in the name Thank you, Ketan and Aaron, your answers have lead me to a root cause: the Lenovo "TVT Backup Service" (rrservice.exe) is started each time the Lenovo backup program starts.

Is there any way to solve this problem? Is it some kind of bug in Windows 7? Or a bug in programs? Or is it a problem buried in the standard Windows USB drivers that don't correctly distinguish between fixed and removable drives? Or a BIOS problem of my ![]() Offline status sets a persistent policy for that particular disk). The only ways to safely remove the external USB disk are either (a) to shut down the computer, or (b) use the Disk Manager to set the disk "offline" (I then have to use the Disk Manager the next time I plug in the disk to set it back "online", since setting ![]() ![]() I always use the "Safely Remove Hardware" procedure to remove external disks, even when configured for "Quick Removal" when these transactional NTFS handles are open, that procedure always fails with the error message that some program is preventing removal. ![]() There is no consistency in what program usage will provoke the problem. I do not know what program or system services initiate the use of these files, the disk is configured for "Quick Removal" in the Hardware Properties sheet. Sometimes I am unable to remove safely a USB external drive because the System process (PID 4) has open handles to several of the Transactional NTFS files that are stored in the hidden system directory \$Extend\$RmMetadata on the external disk. ![]()
