Is there an option which enforce not to check ACL for specified volume?

For example,
There are 3 NTFS volumes.
C:
D:
E: <- disable ACL check?

E: is the specified volume.
I want that all process(includes Internet Explorer with protected mode) can write E: with no restriction, but not on C: D:

Is it possible?

When mounting, try -o uid=xxx where xxx is your user id, you can find it out with the comand id. –  ignis Nov 9 '12 at 8:14

I don't think you can disable ACL, may be wrong so some please correct me if necessary.

Why not just give full permissions to everyone on the base of E: and tell it to apply the setting recursively?

Setting permissions once, as @DMA57361 explains, is no real solution, as ACL problems may still occur later and suddenly there is a subtree of the folder structure that is inaccessible e.g. to your backup routine. When unnoticed, this may cause a loss of data and when noticed it may at least cause a huge annoyance.

Think e.g. about a 100.000 files personal drive of which backups where made using robocopy or rsync and hard-link copies of the folder structure for preserving older versions without wasting storage space. If some ACL conflict occurs, recovering the permissions in windows requires iterating over all those maybe millions of file system nodes, which takes... forever.

So for a data-only drive on a single-user system like a notebook fully disabling any form of permissions would sometimes be preferable.

Currently I am trying to use UDF as my backup file system. For all I know it doesn't have journalling but compared to FAT32 it doesn't have problems with files beyond 4 GB.

Windows can format drives in UDF using in the command line e.g.

format E: /FS:UDF

As of today, Windows 7 uses by default UDF 2.01, but the /R flag allows selecting a specific version up to 2.50.

Sadly though I found barely any information on experiences with UDF on hard drives other than people using it as a cross-platform file system as a more modern alternative to FAT32.

I believe this doesn't fully answer the question but I'll leave it as it seems like useful information. –  slhck Sep 17 '12 at 18:19
