I recently bought a external hard drive to store some data on. I use Linux but I am not a power user. If I format the drive to EXT4, is it possible for the permissions to ever screw up and I lose access to my data? I will be plugging the drive into several different linux based computers at work and I frequently hop distros on my main home machine.

I need to make sure I don't lose any data because I overlooked something. I am not familiar with EXT 3 or 4.

So far I have done this :

  1. Formatted drive to EXT4
  2. ran gksudo thunar and changed the permissions to my user account and all settings to read/write
  3. Wrote all the files I need to the drive

I really appreciate any help.

You probably won't lose any data, but it will eventually become readable to anyone depending on the command options you provide when mounting the drive.

yeah, that is exactly how I need the data to be read. Able to be accessed on any computer. I am going to clean install a 13.10 distribution soon and the hard drive will act as my only backup until I can get it installed and copy the files back over. What commands should I run to ensure I always have access to this data? – EXTdumb Oct 29 '13 at 22:07
Just mounting the device with the default options should be enough. – David Oct 29 '13 at 22:29
Thanks, I really appreciate it. – EXTdumb Oct 29 '13 at 22:40
Sorry, but why not accept the obviously correct answer?^^ – David Nov 20 '15 at 0:26
