Bug ID: 522977
Summary: Uncommanded micro-realignment of partition during
resize causes multi-hour disk thrash.
Classification: Applications
Product: partitionmanager
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR

DESCRIPTION
When RESIZING a partition ONLY to the right the program MOVES the LEFT of the
partition without instruction. There is no warning other than the text string
and there is a MONSTROUS consequence. When using magnetic media for long term
archival, the move (of less than 1MB) forces a MULTI-HOUR long process of
copying every thing on the drive in 1MB chunks (extremely slow) and uselessly
moving them a tiny amount. The problem is the forced realignment of the
partition. When resizing forced realignment of the beginning must not be a
default, at least put up a message with a warning (AND IT'S CONSEQUENCES) and
an option not to realign the beginning of the partition.
STEPS TO REPRODUCE
1. have a magnetic media HDD (not SSD) with a large archive on it, originally
formatted by windows 7, with spare, unallocated disk space "to the right" (from
an old now deleted partition)
2. unmount, select resize, drag the right hand edge to the right
3. "go"
OBSERVED RESULT
You are now trapped unable to power down or otherwise touch anything for many
many hours, cancel demands completion of the current step.. which is multiple
hours long. The poor disk is now reading everything in micro-sized chunks and
the poor head is dancing back and forth the entire time. I don't at this time
know if I'll have lost the archive as a result of this, I'm hoping the backup
of my archive is still good.
EXPECTED RESULT
LEAVE THE EXISTING DATA PRECISELY WHERE IT IS. (shouting).. sorry,
micro-realigning an EXISTING drive is not a great idea, even on a SSD, but on a
HDD it's absolutely terrible, micro-aligning a drive to larger boundaries is
fine when setting up but it's a dreadful idea to do that afterwards.
