LS-Q6.0TL/R5 E15 Error Following NTFS Format

[Kane88]

If you can't get that method of copying the boot files directly to work right:
And given the physical disk problems you're having:
It is probably easier for you to just TFTP boot with a set of wiped drives that have been error checked first.

It appears you've got some kind of bad blocks going on with your disk(s), and these need to be remedied no matter what.

You're using AOMEI, and that software definitely has the capability to wipe drives and also to surface test them.

I would wipe the drives with AOMEI, and surface test each one of them with AOMEI also.  And you're going to want to replace any and all disks that do have bad sectors.  You definitely don't want to be using them as boot drives in the NAS.  If you're still not sure if the disk is bad or not, look for an app called hdsentinel.  https://www.hdsentinel.com/  Even the free version of the app will definitely tell you if the drives are bad or not.

Then, when that is done, I'd setup for TFTP boot, unless that device has an EM mode that can be activated.  I don't think it does.

If you have two pc's, it's pretty easy to TFTP boot.  I've not tried your specific model, but I have done the LS-WVL before.

I'm pretty sure TFTP files for the V-Series (LS-VL, LS-WVL, LS-QVL) works for that one you have, and I have the files if needed.
