Hello, edd_id is a nice small util of udev to match device to its edd record (/sys/firmware/edd/int13_ dev8X). Looking at its code, the way it matches devices is only by their mbr signature. Therefore, if the disk is wiped (or new), it won't be able to match anything, and will return 6 (no valid MBR signature). I think in such case, another method for matching should be considered. the records in sysfs have a file named sectors, which is the device capacity in sectors. proc holds a similar file for kernel devices in /proc/ide/[hs]dX/capacity. These files can be compared to match device to edd dev... If there is more than 1 device with the exact same capacity, it might print the first or not print anything, and exit with error. I agree the best way to match is by signature, but if it is not found - IMHO the alternative way should be taken. -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
