what type of SSD?
I'm not sure but a friend of mine has a RevoDrive X4 SSD, this drive has an integrated raid controller that stripes data across four different internal SSD's.
So, you might need to load raid drivers in windows or during windows setup to get it to work properly as a raid disk. Otherwise yes, you will see 4 independant drives.

so go to the drive manufacturer's website, go to the support/downloads section, and look for drivers for the drive

i know this is kinda counterintuitive because hard drives don't typically need drivers, but the high-performance SSDs use internal raid and so they do.

i'm sure you're already doing this but to get the most performance out of the SSD you should use it as your system (boot drive) and install windows on it, you need to load the drivers for the drive during windows setup

Since this is a laptop, it is unlikely this is a PCI-e based drive like a RevoDrive.

If it's showing up as 4 drives, that means there are 4 partitions on it.  You can use a partition management program to remove them all and create one single one - EaseUS Partition Manager http://www.partition-tool.com/ is free.

ZShaver: yes, i think you might be right it has a build in raid controller or something, but i cant seem to find anything about it on the net.
Or, maybe its supposed to sit in a pc where the raid-controller is on-board.

Callandor: i tried to remove all partitions, but couldnt. I think its more likely that it really is split into 4 disks. Partition-tool looks cool. Amazing if it is really free, with all the features it has.

That looks like a low-insertion force SSD made by Samsung http://www.aliexpress.com/fm-store/314625/211437297-533422864/For-Samsung-1-8-128GB-LIF-SSD-Raid0-890M-S-MZRPA128HMCD-000S0-MZ-RPA1280-0S0-For.html.  Did you order this from overseas?  It seems to only be available in Asia, so support is going to be minimal.

Its a used disk. I has been used in a Sony Vaio before. I dont know which one. And according to your link it should be compatible with my laptop, which is a VPCSB1V9E. Only problem is how to get it to work properly. Yeah, probably not so good chances for support.

post-install with windows vista/windows 7 do this:

click start
in the search box at the bottom of the start menu type diskmgmt.msc

you will see a list of disks, and the partitions on those disks
right click the 2nd, 3rd, and 4th partition, and delete them

right click the first partition and click extend and leave everything at defaults and it will resize partition 1 to the full size of the disk

I will include a screenshot of my diskmgmt.msc, in the screenshot, you will see that Disk 0 has 2 partitions, Disk 1 and 2 both only have 1 partition

so this should work whether it is a system drive or an added second drive

you shouldn't have to pay or download 3rd party tools to do any of this

also, if still encountering the issue please post a screenshot of your diskmgmt.msc so we can see the layout of the disks

hi - i decided to give up. Be cause i think the disk is intentioned for an onboard (MB) raid-controller which is present in other models than the one im trying to make it work in. That could also explain why it has 4 disks in one.

I tried all kinds of ways to remove partitions and make it ONE partition, but it will not let me do it. I tried to make a spanned partition using all disks but it wont let me do that either. Was an interesting project though. Thanks a lot for the support.
