One of our customer decided to go with brand new range of dell latitude laptops. The customer is running SCCM integrated with MDT. The moment they started imaging the laptops using SCCM, they got an error. Task sequence has failed with the error code 0x800700A1. For more information, contact your system administrator or help desk operator.
This error occurred while imaging new laptops only. On other old laptops, the operating system deployment worked well. Error 0x800700A1 translates to disk being RAW format.
Probably the hard disk format on new laptops is not something that SCCM likes. If the partition is in RAW format, it is always recommended to format it before the OSD. In other words before a package that gets cached to the hard disk, the disk needs to be formatted properly. Below is the screenshot of the error.

To fix the error task sequence has failed with the error code 0x800700A1, you could try the below steps. Basically we use diskpart commands to format the disk. In addition here is the link for diskpart commands and diskpart command line options. First of all in the WinPE environment, press F8 which brings up the command prompt. Type the below commands in order.
diskpart list disk (lists the disks) select disk 0 (0 being the disk to setup) clean (wipes the disk) create partition primary (creates windows partition) select partition 1 format quick fs=NTFS (Format primary partition) assign letter C exit
After performing the above steps, restart the machine and try the OSD again. This time you shouldn’t see the task sequence failing with error 0x800700A1.
