Does CBT work on hidden partitions?  I have a partition that I usually hide but occasionally unhide to add files to.  When I unhide it and take an Incremental of it, CBT Init Success never appears in the log.  And there's no running man icon, grey or blue, on that partition.


So, I'm guessing CBT only works on visible partitions that are visible at the moment Windows starts?


Thanks!

Hi @dbminter,

I'm not sure what you mean by 'hidden'. Are you simply removing the drive letter or taking the volume/disk offline?

CBT attaches to all volumes attached to the system that are backed by non-removable storage media.

A volume is a file-system construct that is normally stored on a single partition, however; a dynamic volume can be split over multiple partitions on multiple different storage devices.

CBT will only track changes on NTFS formatted volumes for which it is enabled and are online.

An online volume without a drive letter can still be visible to Windows via a volume GUID path or a device instance path and so CBT will still perform tracking for these devices.

Unfortunately, the only way for Windows (and CBT) to determine if a storage device is classed as removable media, is if the device driver for the device flags it as such.

USB FLASH drives and Floppy Disk Drives are normally classed as removable media devices. CBT does not attach to volumes on these devices due to their limited size and speed.

USB attached hard disk drives are normally classed as non-removable, because the actual storage medium is fixed.

I hope this information helps.


Kind Regards

Jamie

Well, to be honest, I'm not entirely sure what "hidden" means in my case, either.  I'm hiding and unhiding the partitions with AOMEI Partition Assistant's Hide/Unihde command.  It does change the drive letter from X to *.  And the drive disappears from File Explorer.  The exact process of what AOMEI does, I couldn't say.


Hope that helps.
