Sean's Windows 7 Install & Optimization Guide for SSDs & HDDs - Page 7

Ya I changed my original thread: http://www.overclock.net/ssd/1103319...mpilation.html

To reflect that change of not turning off windows defrag given it seems to be not necessary anymore.

I do agree with using a Pagefile of at least 1Gb because I've had programs be pissed at me for turning it off, so I just left it at 1000-1000 and no issues

Hey Sean, gotta jump on this bandwagon, from a "need to know" aspect. Can you provide some insight. Below are the "standard requirements" for a GUID Partition Table (GPT) boot device.

Every GPT disk must contain an MSR, or the DATA on the disk can't be accessed properly. In your formatting senario, running diskpart on your functional SSD, are you sure you ended up with GPT, rather than MBR?

Diskpart is the only way you can see the MSR, but with the caveat below. The MSR, may not show up, without the ESP.

On another note....

Although it is possible to eliminate the ESP (It is very similar to the 100MB "system partition" in MBR), it is not adviseable. The ESP contains a very important piece of information as outline below:

A very important thing that is contained in this partition under GPT, is a "legacy" Protective MBR at sector 0 of the drive. This ensures a protection of the GPT disk from MBR disk tools such as Microsoft MS-DOS FDISK or Microsoft Windows NT Disk Administrator, as well as other disk programs that run in the pre-OS environment.

These type of programs are not GPT "aware". They therefore cannot access a GPT disk. This type of legacy software that does not know about GPT interprets only the Protected MBR when it accesses a GPT disk. These tools will view a GPT disk as having a single encompassing (possibly unrecognized) partition by interpreting the Protected MBR, rather than mistaking the disk for one that is unpartitioned/unformatted etc... It ensures that you can't, (or often can) run a utility outside of the OS on a GPT partition, that is looking for MBR information.

Without the ESP partition, these "legacy" (only to the new GPT disk) programs, cannot be run on a disk formatted as GPT. They actually can be run, but usually with unexpected results... "Oh ****! Where'd all my stuff go?"


Although the UEFI stores some information regarding the pre-boot environment in its firmware, it also uses this partition to store some additional preboot information. This will become more important down the road, as the UEFI starts to mature, and is used for more than just booting the PC.

Well, now I'm not sure where the 4096 came from. It' still a multiple of 512, so it doesn't really matter since it aligns properly.

that was awesome.

Oh and the people asking about 1024 vs 4k. Drives are now manufactured w/ 4k. Best to give them what they want!

EDIT: I do not know what I'm talking about

Nice read actually but this caught my eye:

The I guess the question is the relevance to SSDs, rotational media is a sure thing.
