According to a recent posting by SanDisco SanDisk is making new drives as Fixed Disc in support of Windows 8 requirements. So if you buy a flash drive try to ensure it was manufactured recently.

Thanks, that's an interesting rumor. But I've already bought a drive and I'm pretty sure I should be able to run Windows 8 to go on it.
I tried using PartitionGuru Pro but I didn't manage to make it fixed disk. Is it the USB to HDD option? What exactly did you do when you (nicoyeyo) ended up with a fixed disk version?

Sorry the delay JvdP.
Open Partition Guru PRO, select the drive you want to show as a fixed disk,
Go to menu "TOOLS", and select "MAKE USB-HDD booteable disk".
The program will show a warning that all the data will be lost (so back up all data first!)
After that you will have to unplug your flash drive, and plug it again.
Try this at your own risk. My flash end up showing as a fixed drive accidentaly.
Please post your results.
PD: my drive stills in that mode. Partition Guru support told me to try some USB Disk Production Tool (PDT). So I´m googleing a little.

It seems that the Sandisk Extreme is too new, or it has no support tools:
Is there any firmware update that can solve this problem? (return to removable setting)

Just searching for the removable bit about CZ80 and see this thread.
First I want to say the I'm a BIOS guy, and have knowledge about how MBR/GPT works.
And yes, if you want to build a Windows to Go enviroment on dongle,especially if you are using UEFI BIOS and you would like to use GPT, you need a "fixed" HDD, This is due to the booting rule for the GPT, it needs a EFI Systemp Partition, which is a FAT32 partition with speicified GUID, and the Windows itself needs a partition for itself, which is NTFS and have another GUID. So you definitely need TWO partitions.
But this is not my question.
Here is the story:
My old CZ80 which I bought last year is not worksing anymore, so I contacted my local dealer in Taiwan, and have it exchanged. Meanwhile, I bought another CZ80. This happened today, and now I got 2 CZ80 64GB.
Then I just realized they both are reconized as fixed drive! As I can recall, my old CZ80 is reconized as a removable devie as the previous posts here. I'm wondering if Sandisk changed the firmware in the USB controller? Or this is caused by OS enviroment? Although I'm a bit happy that I got 2 very good usb thumbdrive for Windows To Go, and the performance is even better than some other thumbdrives which is listed on Windows To Go certified list. But on the contrary, these 2 CZ80 are reconized as fixed HDD, and I can't disable the write back cache in devicemanager, this means I have to use the safe removal option everytime before I remove them from the USB port. This is a bit annoying, and the data may lost if you forgot to select the safe removal.
So my question is:
1. Why this happened? have Sandisk changed any firmware settings on CZ80?
2. can Sandisk provide a tool or some way to change the settings? since it seems there are 2 versions of CZ80 now.

This was changed due to the new requirement for Win 8 certification. Fixed disk is actually a requirement for Win 8 certification. This is a deliberate change in the FW of the Extreme USB 3.0 flash drive and no tool will be released to flip it to removable. This is not a bug it is purposely done for Win 8 certification.

So all the newer ones with the Win8 cert logo on the box are set to non removable? Maybe Sandisk sould advertising this change on the box since the new CZ80 would be the best WTG thumb drive on the market . The price is lower then the certified ones and the performance is similar (may be even better).

Hi, I bought a Sandisk Extreme 64GB and it's showing up as a removable storage but I need it as a fixed drive.
I wanna use it for Windows To Go.
It's new, I've received it yesterday so if you have the same pendrive as fixed drive and needing as removable, I can send my memory if you send me your memory too.

lets say some users need it as fixed and some as removable, so its up to sandisk to SUPPLY A TOOL to change the bit, thats the only real solution here.
I got the extreme 64gb 4 weeks ago and it was fixed, first i was upset but then i learnd how to handle it.
i use it not just for windows on the go but also for windows 7 (yes thats possible no problems).
today i got the new 128gb pro for a hefty 200$ just to see its not fixed, who cares i told my self and started some win7/win8 installations.
now the problem is not the installation by itself, its windows which firstly wont install with its installer on usb fixed or not fixed but you can skip the installer and have windows installed. second comes that windows just cant work with non fixed usb drives, windows update and many other system relevant tools just wont work with some kind of permission denied error and you cannot get around this as far as i see.
by the way how the heck can one know if he gets fixed or not fixed drive since there are both types out there for the same drive.
