Getting error trying to format drive

Hi, what about MacBook Air 11" 2012 where there is no SATA cable?

While doing the partition, it shows error like this;

Partition failed

Partition failed with the error:

Unable to write to the last block of the device.

The drive is a custom blade drive in, I have replaced several of them using drives purchased from OWC with success.

Sometimes the board needs to be resoldered using a reflow system if replacing the drive doesn’t work which is very expensive.

I have occasionally done a ‘botch’ job by removing the board and putting it in a 150c temperature oven on a silicone mat for an hour or so but I don’t recommend it as it is very easy to destroy the board by overheating or warping if it is cooled too quickly
