Sorry I cannot reproduce as I have no access to a ARM based system. Testdisk package is correct on x86 / x86_64 platforms.

I have just rebuilt package for armada375 with DSM 6.1 toolchains from my PR #2727. Packed as a zip because of GitHub restriction. May you please download, unpack and manually install this package to test it ? Thank you in advance

Hello Yves, having installed manually the attached file testdisk/photorec is working properly! Thank you very much.

Just out of curiosity, could you tell me what was the issue?

[ymartin59]

Hello. As packages available in repositories are built with DSM 5.x toolchain, there is high risk produced binary cannot work with DSM 6.1 glibc and kernel versions. I have no idea when DSM 6.1 packages may be published to repositories but it is probably time to do so.
Please close this issue. Regards

Could you build a DS414 (armadaxp) version for DSM6? Or at least tell how to make sure my toolchain and dependencies are correct to compile testdisk and photorec?

On my DS414, with the current community Synology packages it ends up like this:

$ /usr/local/testdisk/bin/testdisk -v

Version: 7.0

Same for photorec. I suspect that it was not compiled to take into account this architecture. Since I cannot compiled testdisk/photorec myself, apparently because of issues with the toolchain, it seems to be a dead end for this model.

Anyone having the same issue with a DS414?

@julienbenjamin there is a current PR #3795 for synocli-disk and it updates testdisk to version 7.1

on my armada370 (DS-115j) it shows like this:

admin@DSxxxxx:~$ testdisk -v

You can clone the branch hgy59:synocli-disk or wait until the PR is merged and published.
If you clone the branch there is a do-it-yourself package that contains testdisk only in the folder /diyskp/testdisk.

my issue is that after i install from the synologycommunity repo and i go to the directory using SSH and when i type "testdisk" nothing happens it says its a bad command.

DS716+
DSM 6.22

@rp4k did you install "SynoCli Disk Tools v1.0-1"?
This package contains testdisk Version 7.1 and is available since 4 days.
