Last Logical Drives Dissapear
Nov 7, 2009
I've bought this Sragate 500GB (Recognized as 465GB) HDD and moved everyhing into it. Partitioned it during 7 installation and here are my partitions all in NTFS:
Primary (101MB) - NTFS - Created during Windows 7 setup - I'll delete when I'm ready to install a new OS
I installed my Windows 7 and winxp in the 2nd and 3rd primary and I switch between these two by activaving the appropriate one. when I'm in XP and activate 75GB primart to boot in Windows 7 something strange happens:
Except the 1st logical drive, any other logical drive I have after it dissapears and turns into unpartitioned space. and it seems to be a bug of windows disk management tool or limitation in winxp. the point is that there's no such a problem when I do the same in Windows 7 exactly.
Can anybody give me some advice how to fix this?

Just new here, i am right now installing my new-built PC with Windows 7 Enterprise.
Unfortunately, i have already some problems. My hard drive is a 1 TB WD and on setup i made a primary partition of 50 GB for Windows 7. I thought to partition the rest afterwards and there is the problem. The installation went without any problem, but in diskmanager i cannot see the option as i saw in XP to choose between a primary or an extended partition.
I wanted to make a large extended partition of the unallocated space and then divide it into some logical drives to hold my programs, pictures & films,... etc. As Windows 7 makes primary partition always i am limited to 4 partitions and that is not enough.

the key of this new post is;I AM SCARED that the scenario i had before (all JPGS pictures vanished, and nobody was able to find what was the cause) could be repeated again.why i am saying that?in this system (new HDD with fresh windows 7 install) have few pictures, while scanning (superantispyware)the the old disk (the one were all the pictures were delete by an unknown reason) i notice one picture was missing, but i found instead a file named; "EL 71B9.tmp", by certain reason i decide to copy the file and to change it's extension to jpg, and voila, my picture was there.

I wanted to know if there was any way i could make windows 7 my only operating system. Currently i have a dual boot with xp and 7. On disk management xp is listed as D: (System,Active,Primary Partition) and 7 is listed as C: (Boot,Page File,Crash Dump,Logical Drive). Is there any way to delete windows xp and have windows 7 be the primary partition without reinstalling it. I already moved all of my data from xp to windows 7. I had hoped to delete all of the data on XP and incorporate the newly unallocated space into windows 7.

I've often heard that the OS should be on a drive (logical drive) by itself so that, when it gets a problem, you can just re-install a new copy of the OS on that drive. However, isn't the OS modified when you install programs?

I have 4 partitions...1 with 7, and another with Vista. I want to put XP on also, but of course I can't create another primary. I'm pretty sure I can add XP on a logical, but don't know how. Am I right, or am I out of luck with XP.

After clean installing Windows 7 to second partition dual booting with XP, I notice that the Windows 7 paritition is marked "logical drive" in Disk Management. XP is marked primary active.
Are there any reasons why an OS should not be installed to a logical drive?

i had XP pro installed on my c drive (250gb) for a while,,,a month ago i have installed windows 7 enterprise to another hard disk (500gb) to test and get used to it while i keep my xp...so i have dual boot without any problems..
i never actually looked at it before up until today when i decided that its time to get rid of xp and keep the windows 7 as my only boot option...
as some of you have experienced before i had problems deleting the xp completely due to it being the system drive,etc..
while i was playing around i have found out that the hard drive that i have installed windows 7 has no primary partition but only a logical drive where the os is installed...while the hard drive of the xp is system drive on a primary partition...( I AM ATTACHING THE SCREEN-SHOT OF MY DISK MANAGEMENT)
so now i have a dilemma,,i need help!!
what i ultimately want to do is to get rid of XP completely and keep my 7 as my only boot.....what the heck do i need to do to accomplish that?
i have unsuccessfully tried to delete ,format the xp manually,,,i have physically removed the xp drive which resulted in no boot at all,,cause it has the boot file...
im stuck with a drive which i cannot format,,and if i do it , i cant boot windows 7...
1 thing i didnt try is to format xp drive with xp cd setup...it will result in no boot...and boot the pc with win7 cd and repair the boot sector....i don't know if it will work and i don't trust it...i dont want to lose my windows 7 setup as i have installed all my software and settings...
the fact that it is installed on a logical drive bothers me a lot! help?

My friend recently upgraded to 7 with my help. However i made the mistake of making it a logical partition. Once he deleted his old Vista partition, the system was unbootable. Now he needs a way to convert the logical partition to a primary one. I had him try use gparted live to convert it, but gparted doesnt have that option. My next idea was to run puppy off a USB and use a partition manager on that.

"Windows 7 will be able to take advantage not only of faster CPUs, but of multiple processors on a single chip. The 64-bit edition of the operating system in particular will be able to support over 64 Logical Processors per machine.
In this regard, Microsoft underlined the need for software developers to adapt their applications in accordance with the evolution of processor chips and that of the Windows operating system.
Essentially, consistent gains in performance are synonymous with using parallel programming techniques in concordance with many-core processors. This is where non-uniform memory access (NUMA) comes in.
“The 64-bit versions of Windows 7 and Windows Server 2008 R2 support more than 64 Logical Processors (LP) on a single computer,” Phil Pennington, Windows Server Technical Evangelism, revealed. “New processors are now appearing that leverage non-uniform memory access (NUMA) architectures.
Within the near future, a system with 4 CPU sockets, 8 processor-cores per socket, and with Simultaneious Multi-Threading (SMT) enabled per core, will achieve 64 Logical Processors. Many server-class solutions will need to be architected with NUMA awareness in order to achieve linear performance scaling on 64+ LP systems.”
NUMA is a designed to allow a way around the limitations of the processor bus. Because of its non-linear characteristics, each processor is more intimately connected with its proximate memory, rather than with all the memory available. Unlike the Symmetric Multi-Processor (SMP) model, in which processors are all on par when it comes down to memory and I/O access, NUMA allows for memory access optimization.
“There is nothing the matter with NUMA – machines with non-uniform memory access speeds – of course, other than the fact that they introduce complex, hardware-specific programming models if you want to build applications that can harness their performance and capacity effectively.
What is decidedly new is the extent to which previously esoteric NUMA architecture machines are becoming mainstream building blocks for current and future application servers. For the connected applications of the future, our ability to build programming models that help server application developers deal with complex NUMA architecture performance considerations is the singular challenge of the many-core era,” Windows Performance Engineer Rick Vicik explained.

So, I want to have Windows 7 Home Premium 86x and 64x versions installed on my PC with dualboot. I have 86x version of Windows 7 installed already. So, for 64x version, I have to create a new partition. The problem is, I already have 4 primary partitions, so I can't create a new one (I read somewhere that Windows have to be installed on a primary partition). Here is the picture: (Don't mind disk 2, it's just the external drive).
If I try to create a partition on "Unallocated", Acronis Disk says this:
My question is, which of these partitions on disk 1 can I safely convert to logical? If I am wrong here and I still won't be able to create a new primary partition for Windows to be installed on. I'm really not so good at this things.

I wish to hold some programs and some data on non-system partitions with no boot requirements.
What are the benefits (performance and otherwise) of using a partition :-
Logical on my MBR style HDD
Primary on my MBR style HDD
Primary on my GPT style HDD
NB I have adequate unused space on both the HDD, My system is on an OCZ SSD My motherboard is not uEFI capable hence cannot boot GPT.

Windows 7 is coming pre-installed on my new PC from Dell. It has two 500GB HDDs.
I want to partition the first drive into just a couple of partitions. I guess I will have to shrink the main partition to about 100GB for the OS and apps.
But my question is: that partition with the OS and apps will be a 'primary' one...what will my next couple of partitions be? Logical? Extended?
I'm not sure how to decide what type of partitions to have.

Earlier in the year I bought myself an Apple Mac Mini. I knew I could run Windows on it and soon installed Windows 7. For various reasons I'd like to run 2 copies of Windows, plus OS-X, plus a shared FAT32 partition which all OSs can see and write to. You wouldn't think that would be so difficult..!Unfortunately, Macs use the GPT disk partitioning scheme (which doesn't support extended or logical volumes), Instead, it can support up to 128 primary partitions. However, these get presented to Windows as if they were MBR partitions. GPT also needs an EFI partition, giving me 5 partitions minimum for what I need. Windows backup & partitioning tools (e.g. Paragon's Drive Backup) mistakenly see this as an MBR drive with 5 primary partitions and subsequently refuse to work.Fortunately, Mac OS-X doesn't actually need to be on a GPT drive. It'll run perfectly well from an MBR drive which should in theory save me one partition (the EFI partition). In practice however, installing Windows 7 on an MBR drive causes it to create a 100MB System partition. This leaves me needing 5 partitions again which gets me right back to square one!Is there any way to configure Windows 7 so that it doesn't need that 100MB partition?

I have Windows 7 SP1 and I should only move the users profiles (without the default profile) and the public folder in a NTFS logical partition.
I should modify the ACLs of the root directory () of the logical partition to still have a coherent and stable system or not? If so, how should I modify these ACLs?

When I select unallocated space in disk management All I get is "New Simple Volume" option. How do I create an extended partition and then logicals on it? I can do this ever so easily in gparted and may resort to that but a bit infuriated at how clunky this seems in disk management.

I had 3 drives. my windows7 was installed on drive C. And I had 130GB unallocated space. I wanted to make new drive in this space with Minitool Partition Wizard.I read in mintool site that you can only have 3 primary drives. My E Drive was not important for me and I convert it to a logical drive and made a restart.Buuuut after restart my Windows 7 wont boot. Now I have fedora 15 and I see that all my drives and files are ok.

I just finished putting together my computer, installed Windows 7 Pro 64 bits. However, both of my hard drives (one SSD, one regular HDD) are showing up as external drives (plug-and-play). If I click the "Safely Remove Hardware" icon, I could actually "eject" both of my hard drives.

I had my friend Dell Laptop. He want me to create a two extra partitions in existing primary partition which is C:The HDD is 1TB in size.One hour ago I had used Dell data backup program and created recovery discs and then formatted the Laptop to factory default. I thought before formatting it will give me options to create a partitions but it did not had any option.

One of the hard disks suddenly failed to initialized. The first problem I found on this disk was unable to open one of the zip files then the machine crashed. After I restarted the machine the HDD drive was missing from the Computer. My computer has 6 hard drives including the missing one. One is Corsair SSD for the OS and the rest are Samsung, Hitachi and WD all of them are 1TB. When I checked on the Device Manager the Drive is there and the device status is properly working. I checked on the Disk Management and I got a message to Initialize the Disk then I followed the instruction. Again I got an error message " Virtual Disk Manager - The system cannot find the file specified." On the Disk Management windows the status of the Disk is "Unknown 931.51GB Not Initialized- Unallocated". I tried to initialize but the same error I got. I did not name this drive but it named automatically RV 01 and the Location is 0.I use Acronis Disk Director to fix the problem but it cannot change the status to online. What I did last week was I installed some programs to the Drive X instead of Drive C.My computer OS is Windows 7 64bits all the drivers and software are updated.

am trying to do a backup of my Win 7 system drive (C, but the backup utility is saying that it must backup by non-system drives (E: and H, which happen to have "System Volume Information" folders on them. They are not system drives. E: is my main utilities drive and H: is my games drive.Somehow, Windows thinks they are system drives, when in reality they aren't.Any ideas on how to change them? When I go in to Disk Management, they are not showing as system drives. They are all partitions on the same hard drive, but there are other partitions not included in the backup.

I have installed windows 7 on a sata drive. I also have 2 IDE drives connected to the motherboard but I cant find either with Windows 7. There are no operating system on these drives just backed up files. When I disconnect the windowes 7 drive and reconnect my old drive with XP running on it, both the IDE drives are visible and working normally.
I have tried clicking refresh on the devise manager but the drives are not found. My floppy drive and dvd drive are visble and working properly. Anyone any ideas?
