I build a new computer every 5 to 10 years, but this time my brothers surprised me, building one for me as a gift. It has an SSD main disk with Windows 10, and I just put in a second disk (a HDD) for storage.

- Samsung SSD 840 PRO Series 256GB - Main Drive with OS and all Programs.
- Western Digital Black 4TB 256MB Cache, WD4005FZBX HDD - Storage/Data Drive

It has been a long time since I built my last computer, so I'm carefully reviewing everything. The current setting is IDE for all drives in the BIOS. The Windows 10 was installed with it set to IDE apparently. Is it true that Solid State Drives perform faster and better using the AHCI instead of IDE controller type? Would either of my drives (above) benefit significantly by switching from IDE to AHCI? Are there any risks that should be considered? (BIOS allows for SATA 1-4 to have one setting IDE,RAID,AHCI, and SATA 5-6 to be IDE or AHCI.)

As I'll likely keep this computer for 5 to 10 years, I hope to optimize it to use all features available for the best computing experience. Appreciate any insights or advice from experienced users. Thanks.


 
Solution


I just ran into the problem. I changed the BIOS setting, but it would not boot windows 10, instead it tried to ask me what language keyboard i have, and if thats going to cause a reinstall.... dangerous. I have no install disks as this computer was a gift built by my brothers. All software (OS+Progs) is preinstalled for me. I better go find imaging software to image the drive before I attempt to mess any further and break it. Any suggestions? I don't want to bloat the new fresh install, so maybe clonezilla which I read boots from a USB could be the right answer. Any other ideas? Thanks!
 
You can clone or image the OS drive using that storage drive. Macrium Reflect has a free version . If you have any data on the WD drive then saving an image is the better solution. If the WD is empty then you can consider cloning the OS drive onto the WD.

Here are the steps to save an image

Re the drive mode,
Here is the long way around by many web recommendations.. It uses a safe mode to change the drivers.

Right-click the Windows Start Menu. Choose Command Prompt (Admin).
Type this command and press ENTER: bcdedit /set {current} safeboot minimal
Restart the computer and enter BIOS Setup (the key to press varies between systems).
Change the SATA Operation mode to AHCI from either IDE or RAID (again, the language varies).
Save changes and exit Setup and Windows will automatically boot to Safe Mode.
Right-click the Windows Start Menu once more. Choose Command Prompt (Admin).
Type this command and press ENTER: bcdedit /deletevalue {current} safeboot
Reboot once more and Windows will automatically start with AHCI drivers enabled.

Here is an easier way that works with 7 and 8.1. Don't know how it works in 10.
But back up your system then you can experiment.

Open the Registry editor.
Navigate to the following key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\storahci

Change the Start DWORD value from 3 to 0.
Reboot your PC enter the bios and set the SATA mode to AHCI.

Then pray!

 


Thank you. This is very helpful. Yes, I have 1.5 GB of our family videos from my brothers on the WD, so I will image and place a copy there instead of clone. The SSD has 33GB total used size, so i assume an image may be about that size.

Regarding Macrium Reflect Free
I just checked out Macrium Reflect and it appears to be an exe file, meaning it has to be installed on the pure new SSD to work. I'm intending to create clean copies to use in Hyper-V when the system is setup, stable, and i figure out how (my brothers highly recommended doing this). So I'm looking for something that allows me to make a bootable USB or Disc that won't install things on my OS drive before I get the images saved. Another interesting thing is that Macrium Reflect free claims it saves the OS but doesnt say programs are also imaged, so perhaps its backing up OS files and not an actual image of the drive that can be restored fully. Do you have any experience with these things to be able to help me understand the facts on this?

SATA optical drive
I have a SATA DVD Burner in the computer which is obviously set to IDE right now too. When I set the 2 harddrives to be AHCI, should the optical drive remain as IDE or does it benefit or do fine with AHCI too?

Once I have the backup/image, I'll try the instructions you provided. Thanks!
 
Karenjolys info (the first method) will work flawlessly without a reinstall.

Enter bios , switch back to ide, you can then boot Windows & follow that info.

https://triplescomputers.com/blog/uncategorized/solution-switch-windows-10-from-raidide-to-ahci-operation/

The same method is tried & tested by tens of thousands of users.

& no, optical drives need to remain ide , always put the optical on the seperate sata controller.
 


Thanks for the suggestion. It may work for some people. But it is not possible in this case. As stated above, there no Windows Install Discs, nor any program install discs, as the system came pre-installed. This is why full drive images must be secured of the SSD before attempting the solutions provided. (I prefer at least 2 with different software just in case there are problems with restoring one or the other.)

But those sound like great instructions for others who may stumble upon this post and have install discs. Thanks.
 


Thank you for the answer. I'll definitely open the case, move the cable for the optical drive to the SATA 5 or 6 which appears to be on a different controller since the BIOS separates the selection choices between 1-4 and 5-6. I'll boot and test it before doing anything else.

I read the link and it sounds like the original poster's suggestion above, so that must be a good way to do it. As clearly stated in the first lines of the link, I'll get my images and recovery tools ready since there will be no way to reinstall programs or OS in the case of a mishap.

My system is so new that there is only 1 account, Admin, no password. Hopefully that will be ok to get into safe mode and back out. I'm concerned because the link seems to indicate that you cannot freely choose to enter regular boot and/or safe mode during bootup with a keyboard key like im used to on Windows 7 Ultimate. But I'll follow the steps after my recovery options are finished. Thanks!
 


No, I didn't mean to imply that I wanted to reinstall. I actually cannot reinstall. Luckily I have a plan now, and hope to implement it tomorrow.
 
SATA optical drive
You can put both controllers on AHCI. Optical drives these days are SATA, like yours, so AHCI suits them fine. And they can install on the same controller. I run an ASUS board with the x99 chipset and have two sata optical drives and two sata ssd drives on the same AHCI-set controller.No problemo.

Regarding Macrium Reflect Free

The app is very flexible, imaging just a partition/ volume or the entire disk. You will notice # 3 imaging option is " to image this disk". Ergo the whole enchilada is captured.And in working order.

I am not aware of an external imaging app that restores from a usb without an app on the target disk but you have likely found EaseUS to try. Do not use Windows imaging as it is unreliable tho I suppose it may work, but we have had several issues to deal with it recently.
Let us know if you find something suitable.

With all due respect to the bros I would just use Macrium. (How can one app infringe the Hyper V operation ?).
 


With a legit windows 10 you can make your own windows 10 re-install media using Microsoft's own tool. It works very well.
 


Oh, so it was fine the way it was. Good to know. I moved the Optical to SATA 5, but I can put back on SATA 2 if SATA drives are backwards compatible and work fine on AHCI. That keeps things simple. Thanks!

I need to image the main pure SSD drive into whatever Hyper-V files can be used. And size is an issue. Right now im pushing 34GB which means every Hyper-V file will be no less than 40GB and probably a lot more so i have work space (Ex. Home Video editing). I really want the "TEST" and "Benchmark" VMs very small. I suppose having Macrium duplicated onto every VM isn't too much of a waste. It can't be more than a 500MB program, right? I wonder if there is some feature of it that actually would be necessary and benefit every VM - I'm not clear on that yet. Right now im working on the fact that once anything has been installed on the Main drive it permanently has changed it.

I really appreciate these ideas. They help me think through my options. I realize people here have a lot of solid experience which can help me. However, I'm not confident I've totally made clear my purpose of this new box, so im filtering each idea through that prism as we go.


I'll feel more confident in learning from everyone here if I try to explain my purpose with this box.
In short:
This is my new main and will be my only computer. I use a computer for 5 to 10 years. Historically my computers degrade into permanent slowness and trouble within about 2 years. I usually build my own system and know everything about every component hardware and software but my brothers built and gave them to me as a gift, so im being extremely cautious this time since i have very little knowledge of what i have, why each part was chosen, how well they work together, and I have no ability to restore anything if something goes wrong (since no install discs of any type, nor hardware documentation were provided - All I know is that everything was purposed from NewEgg). Therefore, my initial plan is to keep the main drive SSD (my first SSD ever) clean. By Clean I mean the Windows 10 + all pre-installed programs. I wasn't even planning to install any Motherboard software or drivers, since Windows 10 seems to have grabbed everything necessary for no yellow exclaimation marks in the device manager, and the system boots fine. I was intending to load utilities, games, and other software into Hyper-V Vms. Then if something go very bad, I can always load a copy of the original VM as a method of restoring, never rising the main system drive. I put my own second (data/storage) drive on, so each VM could write to it, thereby never losing any data if having to switch VMs (only configuration, however i was planning to periodically copy the current VM as a backup too). My brothers insisted that by working only in VMs im more secure and wont have a messed up slow system.

So when I realized the IDE setting was less than efficient for my first ever SSD, it slightly complicated my plan, because now instead of just having to figure out how I am going to image the main SSD drive into Hyper-V files (still need to figure that out), I also now im seeking imaging options to store and be able to restore the main SDD fully OS and programs, full drive, in case anything goes wrong with the AHCI correction in BIOS. Thats about it. It actually sounds more simple having typed it out.

As of now: I tried Clonezilla via USB Pendrive, and saved an image of the SSD on Drive 2. Interestingly it saves a ton of files with the main appearing to be an .img file which ciearly will not load in Hyper-V so this backup (assuming it even works) is only good for restoring the SSD and nothing else. I dont think i trust it, since its 12GB in size, and I know the used space is 33GB. Maybe clonezilla compresses things, but im skeptical.

I also did the Win 7 Imaging from within Windows 10, which I just read people say is not reliable. That image is stored on Drive 2 now also, however while Im an admin and can enter the directories by granting myself permission, by default it is unreadable, and therefore i have no clue if it even grabbed 33GB worth of data. Im nervous about clicking yes to allow admin privilege to enter the directories to check, since changing any details like permissions could be enough to make a restore fail since i have no prior knowledge of this tool.

I've found a list of other options but every one of them is like Macrium which appears to require installing software, which will bloat the pure and clean main drive, and even change things in registry. I'm not inclined to do that giving my purpose and plan written above. But if anyone has some additional thoughts on that, im happy to hear. I'm not confident that I have secured a restorable image and plan yet. Thanks.
 


That sounds promising. I just have no idea where to begin on something like that. But ill look it up.
 


I think your assumptions RE Macrium are a bit off.
It doesn't image only the OS...in fact it cannot do that.
It will create an Image of the entire drive or partition.

And with the Macrium application installed, you can do an Image of any drive.
Or you could create a Macrium Rescue CD or USB, boot from that, and create an Image of any drive. Or clone between two drives.
 
You have two apparent concerns.

First, you feel exposed to cataclysmic events by reason of having to trial-and-error system items but with no windows install disks which would allow you to reinstall should the very worst happen.As our friends above have pointed out, that concern is easily allayed by virtue of the present ability to create your own Windows 10 install software. See USAFRet's and Froberg responses above . Very easy to do and you have the USB drive required. Shit may happen but you will be prepared.

Your second apprehension also concerns dreaded system failure, and arises from your experience of computers' slowly degrading performance over the years. You want to avoid the wear and tear of software and hardware uses (and abuses) that have slowed your previous computers and this HyperV is the alleged solution. The purpose is to operate in virtual machines so when s*** happens you can just revert to the "pure" drive and start again.That is a very complicated approach.

I would advocate a simpler back up design based on Macrium. Consider this approach. Maintain a copy of your pure OS disk ( I prefer cloning) instead of VMs. Macrium provides a simple and free resource to maintain a clean system drive on your system thereby allowing your computer to recuperate from any OS problems that may arise. I have an OS drive and two back up drives. I have lost the OS and one back up at the same time after a failed Windows Update and having the third disk saved me from depression and even worse! These back ups are clones created by Macrium, clones crested of a perfectly working OS drive.

Recommendation
I suggest you clone your pure OS drive (including Macrium) to a separate drive and use the computer freely. I like clones on the system itself since you can just boot to the clone when the OS gets into trouble and clone the drive back . Easy peasy. So you will have three drives, the OS, the cloned OS and the storage drive. That's a plan Stan.

PS
I hope I have not taken too many liberties with your intentions. I merely humbly advise.
 


Okay, so it definitely images and can restore the full drive, got it. Thanks!

Your comment about a bootable Macrium Rescue USB to create the full drive image sounds exactly like what im looking for. Do you know for sure if this same Rescue USB can also RESTORE the image to the drive if ever needed? And do you know if this Rescue USB can mount a secondary drive to write the image to, and restore from since I dont have a pendrive big enough to also hold the image? (Plus I would likely want multiple images over time.) (I wont use Cloning since I have no second drive without data on it.)

You mentioned that I get the bootable rescue USB drive by having Macrium "installed". I'm not inclined to install anything on the new SSD Drive prior to imaging backups and creation of Hyper-V files. So maybe this wont work. But do you know for sure if I can install Macrium on a DIFFERENT computer, with a different OS, perhaps Win7, and then create the bootable rescue USB from that? Or is there a risk that it wont be compatible for proper use on a different computer and different OS (Windows 10 in this case)? Thanks!
 


You are great. I like how well you can read my concerns and situation, thereby giving useful advice.

On first point, I just verified that the Create Your Own Windows 10 is unlikely since it requires a license which I don't how to extract from my new computer. However it seems to me that a full drive image backed up to another location or two would solve this issue by allowing a restore option, for whenever needed.

On the cloning issue, ill never be able to do that. I have no second drive without data on disk. I could save up 6-12 months for another drive, but id like to use the computer now. Of course I do love your idea of cloning it and easily swapping drives as needed. Its perfect if i had the money. Maybe someday.

You are correct on my plan to use Hyper-V. I have 4 different environments planned, each specialized as to software and customized Windows setup. The real interesting point i take from your comment here is the idea of installing Macrium on my permanent drive, and having it freeload, taking space forever in all backups and VMs. Obviously, Id like to avoid that if other options exist. But assuming its not a large amount of disk space, and minimal risk to registry corruption, and that it does NOT slow down the system, won't conflict with software I will be installing, then I suppose I can consider installing it. Once its done it can never be undone - all the wonderful options i have today disappear if i do that. So I'll definitely research those issues i listed for another day before considering doing something so drastic to the pure system. [None of these topics ever mattered before, since I would build my own system and just reinstall for issues.]

I dont think i shared enough information about the Hyper-V plan, so it looked overly complex with no benefit. As mentioned here above, i have multiple environments planned. They can be used at the same time or safely tucked away. There are security aspects to this. Also access is easy and the full screen real estate is available for use by using RDC to connect to them (that would be the only thing I run on the main OS install) - also available from other computers. Hopefully that helps show more depth and benefit to the intention of trying Hyper-V. [I still haven't found out how to get an image of the pure OS that is loadable to Hyper-V yet, so im researching that next.] Thanks.
 


Thanks for the link, it was a good read. I'll get into backup for data protection purposes once I start using the new computer. But for today, im in need of a drive image solution that doesnt require installing software on the drive to be imaged. And im interested in how to create Hyper-V compatible image files from a clean fresh Windows 10 installed SSD.
 


You don't. If you're already running a legitimate Windows 10 OS you have a 'digital license' - select "I don't have a product key" during installation and it will let you install. Once installed, it will activate against Windows servers because they recognize the device. Easy peasy.
