Guys, I am using libparted version 1.8.8. Yes, this is an old version but I cannot upgrade to higher versions at present. There seems to be a bug in function ped_disk_new(). ped_disk_new() calls ped_disk_new_fresh() that sets needs_clobbber = 1. Then it calls, type->ops->read(disk). If the device has gpt partition table, gpt_read() will be called. gpt_read() on finding that the partition table is corrupt, will try to correct the partition table. So, if calls ped_disk_commit_to_dev(). ped_disk_commit_to_dev() checks if disk->needs_clobber is set, will try to remove all known partition table signatures. This is dangerous as we are reading the gpt partition table and at the same time trying to remove all signatures of supported partition tables (in case of corrupted partition tabel). This may lead to loss of data.
I think that in ped_disk_new(), needs_clobber should be set to 1 before reading the partition table. Does this sound OK ? Any help is highly appreciated. thanks, rahul _______________________________________________ bug-parted mailing list bug-parted@gnu.org https://lists.gnu.org/mailman/listinfo/bug-parted
