[solved] How to reset/set iso9660 label like PUBLISHER_ID?
A USB stick was earlier written with Arch Linux .iso installation media.
After creating a new partition table with
parted mklabel gpt, the device does still contain some iso9660 leftovers: PUBLISHER_ID, APPLICATION_ID, BOOT_SYSTEM_ID, USAGE, PTTYPE.
Regression:
- reboot, still the iso9660 properties
blkid -p /dev/sdb
/dev/sdb: PUBLISHER_ID="ARCH LINUX <HTTP://WWW.ARCHLINUX.ORG>" APPLICATION_ID="ARCH LINUX LIVE/RESCUE CD" UUID="2017-03-01-18-21-15-00" BOOT_SYSTEM_ID="EL TORITO SPECIFICATION" LABEL="ARCH_201703" TYPE="iso9660" USAGE="filesystem" PTUUID="20983c3d-15f4-4f72-9887-e46d3faa2739" PTTYPE="gpt"How to set or reset these iso9660 labels?
Or at least the LABEL property because that label is also shown in "/dev/disk/by-label/" for the device /dev/sdb (not the partition).

Re: [solved] How to reset/set iso9660 label like PUBLISHER_ID?
I'd prefer to use utilities from "core". Is there an other option then sgdisk?

dd(1) the entire device, perhaps?

According to grep, this information is stored at sector 0:

Re: [solved] How to reset/set iso9660 label like PUBLISHER_ID?
Hmm, better use | hexdump -C to figure out the location of the iso9660 labelling location on disk. It is stored higher. Starting at x8000 (32768=64 blocks) and ending at x9AAF (39599, 39600=77 blocks), totalling 13 3 x 4 = 12 blocks:
grep -a 'ARCH_201703' /dev/sdb | hexdump -C
