May I know why you want to check sdb instead of sda?
Oops, I made a typo:)
/dev/sdb1 * 2048 234440703 234438656 111.8G 83 Linux
Your sdb is aligned successfully
Device Boot Start End Sectors Size Id Type
/dev/sda1 63 1953520456 1953520394 931.5G 7 HPFS/NTFS/exFAT
This one is wrong.
Old disk management tools did such alignment because they believed that any drive uses 512 byte sectors.
But modern software (starting from Win7 I believe) uses 4KB alignment because it is compatible with advanced format and SSD.
I think you need to fix alignment.
The easiest way to do so is to delete the partition and create a new one, but there are also tools to move the partition and preserve data (google for them)
