Have you ever been annoyed by those ugly capital letters in your USB drive's names? Well I was and here's how I fixed it:
$ hexdump -C /dev/disk2s1 | grep "Pablo"
00000040 80 00 29 08 ac 67 54 50 61 62 6c 6f 27 73 20 4b |..).?gTPABLO'S K|
010000e0 50 61 62 6c 6f 27 73 20 4b 65 79 08 00 00 18 bc |PABLO'S KEY....?|$ dd if=input bs=1 count=11 seek=0x47 conv=notrunc of=/dev/disk2s1
$ dd if=input bs=1 count=11 seek=0x10000e0 conv=notrunc of=/dev/disk2s1
Note: Set the count value to the label's length. Remember that a FAT drive label cannot be longer than 11 characters.$ hexdump -C /dev/disk2s1 | grep "Pablo"
00000040 80 00 29 08 ac 67 54 50 61 62 6c 6f 27 73 20 4b |..).?gTPablo's K|
