Well, I could have just answered to Jim (James) but figured since no one else had answered it might be information that others on the list found useful. Sorry for any inconvenience.

James,

In ftk4 I've successfully mounted as a logical RO filesystem ext partitions from a linux box and hfs+ partitions from an ipad image and from an osx box. Not sure what you mean about mobile device persistent memory images...can you explain that to me?

FWIW

Accessdata is still looking for the answer to this question – can FTK mount non-Windows (hfs+, UFS, ext2, ext3, and mobile device) filesystems as Windows partitions?

The situation. FTK has a number of distinct advantages. One new one is the ability to remotely acquire images (one system at a time) in their workstation product. I had used EnCase and their VFS product to mount forensic images and run Identity Finder scans from Windows. In EnCase Workstation 4.x (and 5.x, I think), VFS would mount the image as a drive, but would only work for FAT and NTFS filesystems. I complained to Guidance Software throughout that time. They represented hfs+, UFS, ext2, ext3 internally as a generic hierarchical filesystem, and you could read/copy individual files, why couldn't they export them. In version 6 of EnCase, they did. But VFS also became unreliable. I would have to attempt the mount more than once, sometimes, I would even have to reboot to get VFS to work. Eventually, I got advice on the Guidance Software support forums … use FTK Imager to mount the forensic image, it is rock solid. This wasn't from a Guidance Software employee, of course, but it did simplify my life, until Flashback.

FTK Imager didn't handle non-Windows file system. Accessdata suggested that I use FTK instead of FTK imager for the mount, but didn't have a list of filesystems that it would mount. I am not yet on their latest version (4), so I wanted to know about where they are now. Also, we are having more incidents involving mobile devices (mainly iPhone, and iPad, with a little android). We were looking at purchasing Mobile Phone Examiner (MPE+) from Accessdata, but wanted to mount the files from a phone to a Windows, and run Identity Finder to determine data at risk.

Anyone have any information on mounting non-Windows file systems as a Windows file system? Does it work with mobile device persistent memory images from mobile devices?
