Considerations for Slow Initialize

The Slow Initialize task initializes all physical disks included in the virtual disk. The Slow Initialize task updates the metadata on the physical disks and erases all existing data and file systems.

In comparison with the Fast Initialize task, you may want to use the Slow Initialize task if you have had trouble with a physical disk or suspect that it has bad disk blocks. The Slow Initialize task remaps bad blocks and writes zeroes to all disk blocks.

The Slow Initialize task initializes one physical disk at a time. Each physical disk displays the Clear state while being initialized. While the physical disk is in the Clear state, the Cancel Clear physical disk task is available. Performing a Cancel Clear task on the physical disk causes the Slow Initialize task to be canceled for the entire virtual disk and all member physical disks.
