Verify writes

If selected, iPartition will read-back data it has written to disk to check that it has been written correctly, and will re-write any data that does not match.

WARNING: We strongly recommend that you leave this option enabled unless you are using a disk image or a RAID system configured for redundancy (i.e. not RAID-0 or “striped”).

Bad blocks are quite common on modern disks, and especially so on units made up from more than one physical disk that are not using parity, mirroring or some other error correction scheme.

Note that this option does not provide 100% protection against bad blocks. We strongly recommend that users follow a regular backup regime in order to avoid data loss, and this is especially important where information is irreplaceable or mission-critical.

We would also like to emphasise that bad blocks are not caused by our software; they are a fundamental hazard of hard disk storage. Indeed, they are so common that disk manufacturers embed a list of factory-detected bad blocks on your hard disk.

Use fast partition movement

You would normally want this option enabled as it can significantly reduce the amount of time it takes to move partitions (depending upon how much of the partition is in use). However, it does rely on the filesystem being consistent. We recommend that you check your volumes for consistency before running iPartition anyway.
