olee Posted October 15, 2020 Share Posted October 15, 2020 I have a flash drive that is a clover macos installer. I'd like to keep that drive around so I can do it again in the future, but I don't want to keep this flash drive just laying around not being used. I'd like to create an image of the contents so I can repurpose the drive, but be able to restore it back to it at a later point ( make it bootable again too ). i tried Disk utility,its not work,cant boot up,seems lack efi partition. thanks.

HenryV Posted November 8, 2020 Share Posted November 8, 2020 (edited) Since OC and Clover kexts may be updated frequently, if you have an installer that uses hfs+ you can back up the installer portion using partclone from linux where x in /dev/sdxy is the lsblk -f disk and y is the lsblk -f partition. sudo partclone.hfsp -c -s /dev/sdxy | pbzip2 -c9 > /your/backup/location/whatevernameyouwant.pcl.gz Example: sudo partclone.hfsp -c -s /dev/sdb2 | pbzip2 -c9 > /media/backup_mac_injstaller.pcl.gz Make sure you have pbzip and compression such as lz4 installed in linux. Using partclone over dd backs up only used sectors. Edited November 8, 2020 by HenryV Quote Link to comment Share on other sites More sharing options...
