Format unit not progressing past 83.07%

[ThatDawgMeta]

I'm attempting to recover a drive that previously experienced a power failure during an attempt to switch to 512k sector size. Afterwards the drive read a capacity of 0B. In order to attempt to recover from this, I chose to do a

./openSeaChest_Format.exe -d PD2 --formatUnit 4096 --confirm this-will-erase-data.

This in turn started a format but its been stuck at 83.07% for hours and hasnt progressed any further. Im worried that disconnecting the drive will cause it to be read at 0B again, and am unsure how best to proceed. when running llInfo 1, this is the result i get.

I dont think the drive has any physical issue as it was working perfectly before and is still detected. Any input is appreciated.

Hi @ThatDawgMeta,

That is odd behavior.
If you run openSeaChest_Format -d PD2 --progress format -v4 > verboseProgress.txt and then share that on this issue so I can review it?
