Bug 77140 – hal 0.4.4 cuts cdrom volume names to 16 characters

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Giacomo Perale 2005-01-08 08:38:26 UTC]

I've just upgraded to hal 0.4.4, and I noted that now mounted cd icons on desktop displays only the first 16 characters of volume name. In volume properties as well names are 16 characters long. Reverting to hal-0.4.2-r1 fixed the problem.

joliet label fix

could you try and apply this patch to the ebuild (see src_unpack for examples)
& check if it has any effect ?

I'm sorry but there were no effects, still 16 characters

[Comment 3 foser (RETIRED) 2005-01-08 19:09:16 UTC]

attach the output of the following command : 

dd if=/dev/<cddrive> bs=1 count=4096 skip=32769 | hexdump -C

where <cddrive> is you cd device, with the cd mounted

well it's quite obvious now : it uses the second label, which uses 2 bytes per char, so you get only 16 chars total.
