ShredOS boots but then stops at "Searching for exFAT/FAT32/FAT16 USB drive"?

[LRSFC-DanJ]

I'm trying to wipe a Dell PowerEdge R720xd server using ShredOS. I've successfully wiped two other Dell servers with ShredOS this week, so I didn't expect any problems with this one, however while ShredOS does boot, it just stops at the "Searching for exFAT/FAT32/FAT16 USB drive" message and doesn't go any further. See below:

I've tried:

• Booting in BIOS mode instead of UEFI mode
• Plugging the USB into different ports on the server

Unfortunately while some Dells have built-in wipe tools in the BIOS it seems this one does not, so I really need to use a wiping utility for this.

Any ideas what's wrong?

EDIT: I left it alone as I had a Teams call to go on but it did eventually boot into nwipe, but it can't see the drives, just the USB, so this might be the same issue as #266 unfortunately.

EDIT 2: I found a GitHub issue #39 which suggests ShredOS should support Dell PERC cards, even in RAID mode?

EDIT 3: maybe this is also related to #270

EDIT 4: lspci -v says the megaraid_sas driver is loaded? so not sure why it can't see it?
