I would like to suggest a new feature. In the case parted couldn't
recognize the partition table on a disk, I think it would be helpful
if parted attempted to check whether the partition table didn't assume
a sector size different from the sector size that the disk currently
uses.
The context is that I recently ran into an issue when I accidentally
partitioned a disk with a logical sector size of 4096 bytes, and then
tried to read it with a logical sector size of 512 bytes. (This was
because of a USB--SATA adapter acting strangely. Physical sector size
of the disk is 4096 bytes.) When I tried diagnosing this issue using
parted, it didn't recognize the partition table, which created a false
impression that the data could have become corrupted.
(This issue is not particularly uncommon; when I finally learned what
was its cause, I could find several posts online describing exactly
the same problem.)
Thanks, I'm not sure how we would be able to detect this.
Probe the device with different sector_size values ?
But this kind of discussion belongs on the parted-devel mailing list,
not the bug tracker.
