This ios 58 cant brick your system because its nintendo originally USB 2.0 ios. Your loader is wrong configured or your drive has malfunction.
- plug your drive temporary to external powersupply.
- Get usb loader gx r1272 or r1272 mod 7
- Drive should be formated to fat32 and using MBR not GPT
- Run a check on your harddrive with Powershell and command chkdsk /f.
chkfsk /f /r will correct corrupt sektors but takes longer
- plug your drive in port 0 (wiiu -> back upper one, Wii -> back lower one)
- set in usb loader correct port, filesystem, single partition
- Try loader cios 249/250/251 with installed d2x v10 beta r52 (only support port 0)
base 56 => 249
base 57 => 250
base 58 => 251
Else:
- Use ios 58 as loader ios, plug your drive in port 1 (wiiu -> back lower one, Wii -> back upper one) and set cios 251 as game ios
If games dont appear:
- use correct game path and supported fileformat
- if wii games dont show up, check the box in usb loader gx for displayed games.
- to run some games it needs game cios with base 56 or 57 to be set.
Alternativ to verify the Problem
Try Wiiflow or CFG Loader. If they work flawless with recognizing the hdd and launching the games, it points that there is a problem with gx loader.
If finally nothing works, your hdd seems maybe not supported. Not every hdd runs well with it.
