I bought a usb external drive and every time I try to copy to it I get lockup when 1.8 GB has been transferred and I can't cancel copy. Reboot required to clear it.
If I copy smaller chunks than 1.8 GB then it works and if I copy several smaller chunks, more than 1.8 GB in total is saved to usb disk no problem. It is only when I try to copy a folder with total of more than 1.8 GB that it fails at 1.8 GB of current transfer.
Running windows 7 64bit with USB2 ports and USB3 HGST Touro mobile pro 1TB external drive which is supposed to be usb 2 compliant. Drive formated using NTFS 4096 blocks size.
Any ideas why transfer would fail for anything bigger than 1.8 GB and is there anything I can do about it.
More hardware specs might help. For instance issues such have this have been observed on systems with NVIDIA USB EHCI chipsets: http://support.microsoft.com/kb/976972

I am developing a program which use huge ram size. Unfortunately there is no way to decrease it. In linux when ram is low I can generate a swap file and mount it to system that solve my problem but in windows how can I do that or is there any api(c/c++) that can use a temp file like a ram?
I've used Win32diskimager to install FreeNAS 9.3 onto an 8GB USB stick, and configured the BIOS of my HP Proliant Microserver to put "USB Device Boot Priority" on High.
However after inserting the USB stick and rebooting the server, it doesn't boot up completely, instead reaching a screen stating
This is a NAS data disk and can not boot system. System halting.
Can someone tell me what I've done wrong?
Thanks in advance.
It turns out you need to format the USB as NTFS rather than FAT32 or FAT16.
I am working on a machine with an older intel CPU (core 2 duo 2.4 Ghz e6600) that doesn't have SLAT and doesn't support Hyper-V.
It is running Windows 8.1 (64 bit) with 4GBs of ram. What software options do I have if I wanted to run a virtual machine, in this case, another instance of Windows (ex. Win 7)?
Am I SOL? Will speed of VM be limited more by ram, cpu, or hard drive in this case?
Thanks,
i think your best option is VirtualBox form oracle, i use it becouse i have the same tipe of procesor, an work really fine for me, the only think you can only instala x86 OS, but anything else works fine.
some spec's for your virtual machines
Windows
Ram 1gb to 2gb, it is fine
procesor one core only
HDD 40gb it almos enough for you want todo (as developer i only use it for testing)
video dont use it unless you need it
linux/unix
Console only
ram 256MB to 512MB
procesor one core only
HDD 40gb it almos enough for you want todo
video is not need here
GUI mode
ram 512MB to 1gb(i recomend use 2gb if your plan to use Ubuntu)
procesor one core only
HDD 40gb it almos enough for you want todo
video dont use it unless you need it
hope help you
How much difference does dedicated graphics and HDD speed matter when using virtual machines?
For the last year I have been using a MacBook Pro 15" with the following specs with great success.
Core i7
8 GB RAM
7200 RPM HDD
Dedicated Graphics card (NVIDIA GeForce GT 330M 512 MB)
I do a good deal of development in Windows so I use VMware Fusion with Windows 7 and Windows Server 2008 as guest operating systems. Everything has worked really well.
Well, recently my wife's MacBook died and we got a replacement MacBook Pro 13" with the following specs
Core i7
8 GB RAM
5400 RPM HDD
Integrated graphics (Intel)
Since the processor and RAM are the same I thought I might benefit from the smaller form factor of the 13" MacBook (can use external monitor when at home) and my wife could use the power of the dedicated graphics for video editing and the like.
So that brings me to my question. How much will a slower HDD and non-dedicated graphics card effect my virtual machine performance? I don't play any games so I never thought I made use of the dedicated graphics card. I don't know if it actually helped with the VM or not. What about the Disk Drive speed? Does this play a major factor? I really never noticed any swapping when using VMWare Fusion. Thanks for any insight.
The difference will be negligable. You won't notice the graphics at all, and will barely notice the difference in speed from the hard drive.
Solid state disks are dropping in price all the time, if you do feel like the drive is "slow" down the track you can purchase an SSD and upgrade it yourself fairly easily without voiding your warranty. (OWC sell DIY SSD upgrade kits for example)
Windows XP as base OS. Laptop has 4GB RAM and 2*2.2GHz cores. About 3 year old laptop
Am using Windows7 in VMWare Player. If I allocate more than 1GB of RAM to the Win7 machine in the VMWare player settings it goes so slow, and is continually swapping to disk.
I've turned off all Win7 processor intensive stuff.

The base OS only reports using aboiut 144MB of RAM to the player. Very weird.
I'm using 2 virtual disks: 20GB SCSI for c:\ and 25GB SCSI for data f:\
Problem: How to tweak Win7 VMware (ie VS2010, Sql2008R2) well on an older laptop. Or use something else?
The problem is that by default vmware player uses file as memory.
Read this for more info & fix
http://communities.vmware.com/thread/46122
If you want to achieve this for all your VMs, you may just add/append following two lines:
prefvmx.minVmMemPct = 100
mainMem.useNamedFile = "false"
... inside the following VMware-wide configuration file:
C:/ProgramData/VMware/VMware Workstation/config.ini (or sometimes settings.ini)
The first line sets the percentage of configured VM memory that should fit into the host memory and the second (as already shown in the prior answer) disables default file-based memory usage.
If you want to apply this to a specific VM only, in order to not alter general VMware configuration, adding the following line to the VM's *.vmx file may be an alternative:
hard-disk.hostBuffer = "disabled"
