I captured an NTFS harddrive image using partimag and xz with multithreading. when i go to deploy the image partimag complains that the format is unknown. i'm using clonezilla-live-20101106-maverick. the image is stored on an ubuntu server and with xz-utils installed. the files can be opened and extracted from there, just not from within clonezilla-live. please advise.
