for dev in $(cat drives.txt); do umount $dev* 2>/dev/null; done The cache typically lives starting at sector 2048 (1MB offset). We will wipe only sectors 0-2047. Use parted with mkpart but do not format yet

for dev in $(cat drives.txt); do dd if=/dev/zero of=$dev bs=512 count=2048 status=progress done This removes GPT/MBR headers but leaves the cache data intact from LBA 2048 onward. Use parted with mkpart but do not format yet . Set the start sector to 2048 (exactly where your old cache begins).
