Shrink external drive partition
by kel_en from LinuxQuestions.org on (#52SGN)
Greetings, all. My name is Richard and I'm a Slackware newbie. 2 weeks ago I replaced Debian 9 with Slackware 14.2 on my core-duo Fujitsu lifebook. So far, everything has gone very well. Thanks are due to all who have contributed to making Slackware the solid operating system that it is.
I want to convert my desktop machine from Debian 10 to Slackware. I need to save a copy of some of the data from that machine. I would like to use my 1TB external HD which contains under 300GB of data. My thought was to shrink the 1TB NTFS partition to 500GB and create a second 500GB partition to use for backup. Then I could use dd to transfer my data partition to the new external drive partition. Do you think it is likely to shrink the original partition without data loss?
Thanks, Richard
