Fw: Fw: How long will this take?

The process is complete. The 4 TB drive has been successfully blanked in less than 40 hours using dd. It got done between 11 pm last night and 12 am this morning. dd showed an overall average write speed of 28.4 MB/s. It was never my intention to start a war. My sincere apologies if I have said or done anything to offend anyone. I prefer to test out new hardware after I buy it and I prefer to blank new hard drives before partitioning and writing out new file systems. Thank you to each of you for your assistance.

I use the manufacture toolkit to test and verify drives.

I use the manufacturer toolkit to zero fill and/or secure erase drives.

They started the first partition inside a physical 4096 byte sector. fdisk pointed this out in red text. The drive uses a logical sector size of 512 bytes, but uses a physical sector size of 4096 bytes. I still don't know the rest of the disk geometry.

If you have any console sessions from before destroying the factory
layout, please post any commands and output that are of interest.
