See if the partition's starting block is 63 as it used to be in the |
| 8 |
past. In this case the alignment is wrong, as SSDs have 4K (or even 8K) |
| 9 |
sectors consisting of 8 (or 16) 512 byte blocks. The starting block |
| 10 |
should be divisible by 8 (or 16) because of the large sector size, if |
| 11 |
not, a file system sector spans over two drive sectors, and both heed to |
| 12 |
be accessed when reading a file system sector. |

The size of an erasable block of SSDs is even larger, usually 512K, it |
| 15 |
would be best to align to that, too. A partition offset of 512K or 1M |
| 16 |
would avoid this. |
