SeaChest-lite SetSectorSize does nothing

[johnteh00]

Problem

When I try to change the sector size on a Exos 16 to 4kn nothing happens. I start the process with the arguments"-d PD3 --setSectorSize 4096 --confirm this-will-erase-data" The warnings and the countdown appear. After the Countdown has hit "0" the consol immediately jumps back out into the promt "C:\" I confirm, before and after restart, with --showSupportedFormats that nothing has indeed changed and the drive is still at 512

Expected behavior

I would expect a progress indication or at least a significant pause for Low Level Format to take place

How to reproduce

Hi @johnteh00,

Can you run this command with the verbose option and save it to a file so I can see what the drive is doing when this happens? SeaChest_Lite -d <handle> --setSectorSize 4096 --confirm this-will-erase-data -v 4 > setSectorSize.txt

Thanks @vonericsen. Weirdly enough, trying it in verbose mode with your prompt produced: "unknown option -- v"; but this time the format worked. It asked me to add "-and-may-render-the-drive-inoperable" to the prompt. And then continued to operate correctly

@johnteh00, that is really odd... One thing to be aware of is single character options only use a single - so maybe it was complaining about that? It's weird that that would suddenly change behavior, so I'm going to do my best to look into it and see if I can figure out how to repeat what you observed.

Can you confirm the version of SeaChest_Lite you are using?

[johnteh00]

I did run it as single dash command. Tried a couple of times. IDK why the error would make it into double dash. Also when calling the command without options, Verbose wasn’t listed under the possible options

@johnteh00, I forgot that SeaChest_Lite does not allow verbose mode, so that explains that error. I have not been able to repeat the behavior you saw where it quit without doing anything, so I'm not sure what is going on there still. I'm doing a code review to make sure I don't miss what could have caused this behavior in case it's something that only happens sometimes.

Invalid argument: SeaChest_Lite Invalid argument: 4 One or more of the options provided will perform a low-level format that cannot be interrupted once started. All background software should be stopped, any filesystems that are currently mounted should first be unmounted in order to reduce the risk of interruption. Do not attempt these operations on multiple devices at the same time to ensure the best possible outcome. Many controllers/drivers/HBAs cannot handle these operations running in parallel without issuing a device reset. There is a risk when performing a low-level format/fast format that may make the drive inoperable if it is reset at any time while it is formatting.

You must add the flag: "this-will-erase-data-and-may-render-the-drive-inoperable" to the command line arguments to run a set sector size operation.

e.g.: SeaChest_Lite -d PD<#> --setSectorSize 4096 --confirm this-will-erase-data-and-may-render-the-drive-inoperable
