Preparing Advanced Format hard drives for Microsoft Windows installations on HP Business Notebook PCs and desktop PCs - White Paper

Frequently asked questions
I am not sure I have an Advanced Format drive. What should I do?
Even if you are not sure you have an Advanced Format drive, you can still follow the procedures
described in this white paper. Changing your installation methods to accommodate Advanced
Format-compatibility does not negatively impact a drive with 512-byte sectors.
I’m an IT professional. How can I ensure an image I create will be supported on Advanced Format
drives?
It depends on your environment and the deployment tool you are using. More information is provided
in Hard drive deployment decision tree for managed IT.
My operating system is Advanced Format-aware; however, I do not have an Advanced Format drive.
Do I need to do anything?
No changes are required to run an operating system that is Advanced Format-aware on a drive with
512-byte sectors.
What happens if I do not align my partitions?
Your Advanced Format drive will work; however, applications may fail because of the unexpected
slow-down.
What impact does the Advanced Format drive have on Linux users?
Use Linux kernel 2.6.33 and above; do not create MS-DOS-compatible partitions.
The RedFlag Linux (kernel version 2.6.31 and above) shipped by HP is Advanced Format-aware.
For information on partition alignment for SUSE Linux, refer to

What happens if I am running an older operating system with conventional drives or a mixture of
conventional and Advanced Format drives?
You can safely set up partition alignment in a mixed environment – or even if you only have drives
with 512-byte sectors.
It is immaterial whether you are running – or plan to run – Windows XP or Windows 2000 or a
newer operating system. However, you must first use Windows 7 or Windows Vista SP1 or later to
partition each hard drive.
Are there differences between Advanced Format drive models?
Some drive models have noticeably superior performance, though slightly higher potential for data
loss.
Many vendors are switching to the Advanced Format drives without making any other changes. Some
vendors have made the transition more transparent to users and have optimized the performance of
their software by delaying disk writes. While these sequential writes can improve performance, they
keep data in the cache longer; thus, if you fail to align one of these write-optimized drives, there is a
greater risk of data loss.
