Most bootable Rescue USB Flash Drives that I have seen require the FAT32 file system. If you are recovering file(s) from a crippled PC using a bootable Rescue USB Flash Drive, is it a common and safe practice to recover (copy) the file(s) to the same bootable Rescue USB Flash Drive? It seems like it would be more convenient to just carry around one USB Flash Drive that can do both file recovery and recovered file storage. I have essentially no practical experience with recovering file(s) from a crippled PC with a bootable Rescue USB Flash Drive. I know how to recover file(s) using either a bootable CD/DVD or a bootable USB Flash Drive. I have practiced this a few times on my Windows PC's, but I would always copy the test file(s) to a different USB Flash Drive. A few examples of bootable USB Flash Drives that can be used for file recovery on a crippled PC: YUMI, Xboot, Kaspersky Rescue 10 USB, Dr.Web Live USB, etc. In YUMI and Xboot you can use many Linux Distros such as: Parted Magic, Puppy Linux, Ubuntu, Linux Mint, etc. Thanks in Advance.
