Re: [sleuthkit-users] blkcat fails to output textfile

[Ketil F. <ke...@fr...>]

Kai,

I see you added the sync Simson suggested, but still no joy? I tried
to recreate your example, and it works for me. I tested by creating a
simple loopback file with ext4 on it, like this:

dd if=/dev/zero of=ext4.dd bs=1M count=200
mkfs -t ext4 ext4.dd

and I used tsk 4.1.3 (compiled from github). What file system (and
file system options) do you have on /dev/sdb1, and what version of
blkcat are you using? Does the block contain any data at all? Add the
-h flag to blkcat to see the hex dump of the block, is it all zeros or
is there anything else there?

Regarding the sync call, I tested with and without it right now with
ext4. If the data isn't written out to disk, there's nothing listed
under "Direct Blocks" either.

Cheers, Ketil
