Package: parted
Version: 3.2-17
I have a valid & pretty standard Windows 10 system on a hard disk with
three NTFS partitions: a small boot partition, a 465 GB main partition
and a small restore partition. The structure is created by fsdisk from a
Clonezilla live distribution. After the partitions are created, parted
identifies my partition table as "atari" with a single partition. Any
other tool I throw at it correctly sees an msdos partition table and I
can boot windows 10 from the disk, so it appears there is nothing wrong
with the disk. Also, it reproduces on 7 different PC's (albeit with
pretty identical hardware).
I don't have a complete Debian system so my options are limited (no
inernet access / reportbug), but this is the test I ran to reproduce the
problem:
1.Run parted; it says I have an atari disk (even though it is a
functional Windows 10 system) 2.Instruct parted to create a new dos
partition table
3.Run parted; it says I have an msdos disk with no partitions (as
expected)
4.Run sfdisk with sda-pt.sf from the Clonezilla image as input
5.sfdisk creates three NTFS partitions on the disk (as expected)
6.Run parted; it says I have an atari disk with one partition
See the full log at the end of this mail.
My understanding of the problem is that the code that makes parted
recognize atari disks in isolated cases falsely indentifies a disk as
Atari if the first blocks incidentally contain data that make (some)
sense when interpreted as an Atari partition table. The chance of this
happening is not high but also not zero (and apparently I got unlucky).
See the parted list (Bug #31111
http://lists.gnu.org/archive/html/bug-parted/2018-04/msg00003.html) for
a more detailed analysis.
The chance of this happening should be zero because If I would use
parted to change anything on this disk it would probably destroy all
data on it (i.e., pretty critical).
FUN FACT: If I change the size of sda2 from 975028224 to (e.g.)
975028222, the disk is no longer recognized as Atari & the problem
vanishes.
