Weird windows 8 installation question

Fri Apr 19, 2013 3:46 am

So... I've reinstalled windows 8 yesterday, made backup of important stuff to my 1TB drive, then destroyed the ssd drive array, booted with parted magic, secured erase both ssd drives, started windows installation... after the first reboot of windows there is a window that shows 2 windows 8, the boot menu. On says it's on volume 1 the other doesn't say anything because its supposed not to exist, but the record is there. So after windows is installed I went to system proprieties, boot and disable the list of various operation systems, now the boot menu doesn't appear. That's the way I've found to resolve this weird issue...

My question is, it wasn't supposed to be there any other installation because I formatted the drives right? Or maybe the information about the old installation was on my backup drive?

Any response is welcome :wink:

Sounds like the secure erase didn't wipe the bootloader making it a "not-so-secure-erase"

I'm not sure, how did you do the secure erase?

Maybe Parted Magic didn't get the previous installation's Recovery Partition or EFI System Partition (if you're using a UEFI system.) Did you see multiple partitions like that in Parted Magic before the secure erase but not after? Or did you see them when you chose the OS partition in Windows installer? Did you format the whole drive during Windows install the second time?

You may want to use the SSD manufacturer's utility instead.

I believe corsair doesn't have any utility to secure erase...

Windows has a built in secure erase as an option.

Secure erasing is not necessary before an install of an OS. TRIM will clean up.

Boot from the windows media and select repair your install. Login and choose the command prompt.

Type diskpart
Type list disk and find the disk you want to secure erase
Type select disk # - the number of the disk you want to secure erase
Type clean all - this will secure erase the drive

I don't have trim, its a raid array with a p67 chipset... Is it possible to do this anyway?

Yes.

You don't need TRIM to execute this task.

Just don't select the wrong drive.

It is the drive connected to the first sata port correct? (I have 2 6gb sata ports on the ssd's)

When you type "list disk" it will show the drive(s) it can find by capacity each assigned with a unique number. You'll use "select disk #" to pick the disk you want to execute commands on; in this instance the "clean all" command.

If you want to be safer just make sure all disks others than the one you're about to wipe is unplugged before doing this. You can't accidently wipe a disk that the system didn't enumerate.

Boot from the Windows 8 media
Advanced Options
Command Prompt
http://peter.upfold.org.uk/blog/wp-content/uploads/2013/02/Windows-8-Automatic-Startup-Repair.png

Note the above picture I referenced off of Google images has the wrong thing circled at the bottom. You want the command prompt, not the automatic repair.

Re: Weird windows 8 installation question

Mon Apr 22, 2013 5:17 am

I haven't sorted out the way you told me, but I've managed to completely erase the ssd. I used parted magic and i selected External (Erase MBR) to erase mbr and gtp data structures. Then I've made a secure erase. Like this It worked, the disk was completely erased.

After this I was seeing the performance numbers of the raid array and it was normal, the numbers were as the first time installation, it was good to see it.

For mistake I've downloaded diskmark info utility, and I saw something that scared me a bit, because some of the values implied that the ssd were damaged. There are 2 thinks it can happen:

- the disk info doesn't work well with raided volumes and shows incorrect information or

- i've damaged the drives by using external erase mbr with parted magic?

Can someone figure this out? (It's strange because my ssd's were bought in different times and some of the information on diskmark info is the same for the 2 of them)

* I have to add that when choosing secure erase in parted magic and clicking ok the action is so fast i can't see the information box saying if the drive is secure erased or not, so i'm not sure if it's normal to a secure erase in a 90gb drive to take less then a second...

What is this info that leads you to believe the drives are damaged?

That does sound a little suspicious to me. But SSDs aren't like HDDs where every sector needs to get overwritten to erase all of the data; they could (in effect) just be doing the equivalent of a whole drive TRIM. This would be less secure in the sense that a really determined person with detailed knowledge of the drive firmware's internals (and the ability to hack and load custom firmware) theoretically might be able to recover data from the "erased" drive, but for most practical purposes it would be equivalent to erasing the entire drive.
Nostalgia isn't what it used to be.

I wouldn't worry about the speed of the secure erase, it is virtually instant. I've done it a couple of times on SSDs, the first time I was suspicious too but found confirmation that it takes almost no time.

Its really fast I guess, other times it was also very fast. But because there was some information left in the ssd after the secure erase (the previous windows boot as i refereed in the beginning of the topic) i was a little worried that it wasnt doing the erase. But performance is excellent so it must have done it ;)

My worry's are about diskmark info (that i'll post in a couple of hours) and a strange behavior of my mouse (i don't know if i'm getting crazy but it looks like its acting like when i bought the first ssd and had to update the firmware because the mouse appeared to stop and jump for less than seconds that is, as it was a firmware problem of the drive) Maybe it's just my imagination...

It sounds like you might be able to enable TRIM with your chipset according to this article:

Yes i've already read this article but it requires some bios file modifications and i'm not very confident to do it ;)

Does not make sense that a secure erase will leave data behind. Sounds like the BCD is in the HDD instead. When you re-install Windows 8 did you unplug the HDD and leave the SSD plugged in alone just to be sure?
The Model M is not for the faint of heart. You either like them or hate them.

No i didn't :-?

This is weird... I've launched diskmark info again and the charts are all blue, saying the drive is fine :o What has happened? -.- Maybe it was because i forgot to install intel rapid storage tecnology? Now i have it and it is ok...
