• T30 slow performance - hard drive running constantly - you clean the machine

  Hello

  I had to reinstall Windows XP from scratch some time ago.  In doing so, my system is now very slow (everything - loading programs, browsing, startup, etc.) even with no charge additional software other than Windows itself with all service packs and updates installed.  I reinstalled several times with the same result.  I have 384 MB of RAM and that you have defined a 512 MB Windows swap file.  The hard drive light is almost constantly on.  It's same with no antivirus software - if I load my machine becomes completely unusable.  I loaded all the latest drives using the Configuration of ThinkPad utility so I should be aware of the drivers.  IBM/Lenovo factory-loaded some specific software (management of the CPU, etc.), as I'm missing when I reinstalled?  I tried everything, but it works just like a dog.  Any ideas...?

  Thank you

  Welcome to the forum!

  384 of RAM is not enough to run XP correctly on your ThinkPad. I suggest upgrading at least 1 GB.

  On other issues: you are using XP mode "classic"?

  Also, is your CPU value "maximum performance" in the BIOS?

  Good luck and let us know.

• Sharing a connection with a possibly infected PC.

  I have two computers, one of them may be infected.

  If I use a hub to share the network connection (plug my modem cable to the hub and then connect each PC in this hub) and a KVM switch allows you to share external peripherals such as mouse, keyboard and monitor, will I have the own computer infected too?

  I don't have a local network (actually I don't know exactly what is a LAN, but I guess that's something that needs to be put in place).

  The own PC is a Vista, the other is an XP.

  Thanks for your help.

  TI computers are connected and sharing of files, then it is possible that infection from spreading (and it seems that you only use the hub/switch by your internet connection, I need you to confirm that) NEVER move you files between two computers by any connection you set up - is that correct?   It seems relatively safe only share the internet connection (assuming that's it, that is - if you also share files between computers while the chances of infecting other computers are high).  The switch for the devices will not cause a problem.

  You should get the infected computer cleaned as soon as possible to make sure it's not more difficult to solve, because the infection (or starting to cause serious problems).

If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

• How to speed up the process of updating after clean install

  original title: updates after a clean install

  I just performed a facility clean my machine that runs Vista Home Basic Edition and is now trying to download all the updates it has had over the past three years (ex-factory).

  However it will slowly (no surprise) and I was wondering is there something I could do to speed up the process.  Currently, I am just by clicking on start - Windows Update and let it download what they want from there.  However I have noticed saying she "Download 80 updates", it installs then say 5 of those, restarts and then says "Download 75 updates"-have I really downloaded updates and then lost 80 them, or he really download only 5?

  I also thought the oldest download first, but I can't seem to find an opption to do this - is - it possible?  It seems just stupid for me to download updates of 2010 before those of 2008 (assuming that's what he does lol!)

  Start by installing the latest Service Pack (see http://support.microsoft.com/kb/935791). You'll have so far fewere updtes to install.

  Also note the following regarding your answer to the question of PA Bear "clean install has been through choice. After 3 years machine has become bloated and slow, and I decided to wipe them fresh, start over and give up unused programs that seemed a good idea at the time. » :

  In my view, it is usually a mistake. With a minimum of care, it should never be necessary to reinstall Windows (Vista or any version). I ran Windows 3.0, 3.1, WFWG 3.11, Windows 95, Windows 98, Windows 2000, Windows XP, Windows Vista and Windows 7 now, each for the period of time before the next release is out and everyone on two or more machines here. I never reinstalled none of them (with one exception--a problem that I worked on for weeks without success), and I've never had anything more than an occasional minor problem.

  It is my belief that this erroneous notion comes from the technical support people in most of the major OEMs. Their solution to almost any problem, for they know not quickly answer is "reformat and reinstall. It is the ideal solution for them. It gets you phone turned off quickly, it almost always works, and it does not need to do any real troubleshooting (a skill that most of them has obviously not in any great degree).

  But it leaves you with all the work and all the problems. You must restore all backups of your data, you must reinstall all of your programs, you must reinstall all Windows and updates of the application, you must locate and install all the necessary drivers for your system, you will need to recustomize Windows and all your applications to work the way you are comfortable with.

  In addition to all these things being long and painful, you may encounter difficulties with some of them: you will find all your CDs application? You will find all the necessary installation codes? You have data backups to restore? You still remember all the customizations and settings that can be installed to make everything work the way you like it? Sometimes there are problems that are so difficult to resolve that Windows has to be reinstalled properly. But they are few and far between; RESETTLEMENT should not be a substitute for troubleshooting; It should be a last resort, to do that once all other troubleshooting by qualified person attempts have failed.

  And perhaps most important: If you reformat and reinstall without knowing what caused your problem, you will most likely repeat the behavior that caused it and quickly find yourself in exactly the same situation.

• A Boot Camp Partition, two Machines virtual VMware Fusion

  After the installation of the Boot Drive Partition *, I see now two versions of the Virtual Machine Boot Camp. Is this normal? Can I delete one with no impact on my Boot Camp? Should I remove VMware Fusion altogether and reinstall so that I can have a clean virtual machine only the partition boot camp?

  *It is on a separate post, but can be linked... Initially, I installed VMware Fusion, without first running training Camp and installed a Microsoft XP operating system on it. It stopped working and I had a lot of problems with Windows that I decided to do a new installation, but this time using Boot Camp. I can see two VMS, (actually 3*), but I want to remove the first virtual machine without Boot Camp. I tried the virtual machine under users/Documents/Virtual Machines, but the directory is empty. I deleted the directory, just in case. When I returned to VMware Fusion, it can still start the virtual machine. I looked through the finder and can't find it.

• Off-host backup methods (like HDS ShadowImage, EMC BCVS, etc.) works in a virtual machine?

  HI Experts,

  Off-host backup methods (like HDS ShadowImage, EMC BCVS, etc.) works in a Virtual Machine (if the volume to be backed up is created on RDM)?

  This means that each such VM who have need to have backup off-host using ShadowImage have their LUNS dedicated (using RDM) and not on VMFS volumes.

  Any suggestions greatly appreciated.

  Jaikrit Negi

  (VCP, NCDA, BCCFP, ASFS)

  If you find this answer useful please consider giving points by checking the correct or helpful answer.

  I'm not sure it's really a 'problem '.  If you take a snapshot of the side storage (BCV, NetApp snapshot, whatever) you're after a point-in-time backup.  The fact that changes to virtual RDM will make a delta file while the snapshot of the virtual machine exists doesn't make much difference insofar as what is in the snapshot storage - except that he has invited at least FS compliant (compatible app is another debate).  You always have a snapshot of time point, and it is always the data that exist when you trigger the process.

  So, with virtual mode, you can use instant VMware (using RAS as VMware tools are installed) and get a consistent snapshot of comments-FS.

  Physical RDM mode, it's tools, usually from the storage provider, in the prompt flush/being suspended.  NetApp SnapDrive one is an example of this.  SnapDrive one uses the same win32 calls to rinse the NTFS.  You can put SnapManager for Exchange, SQL, SharePoint, in addition to this, and now you're app - are as well.

  You can make snapshots of storage of data a VMFS or NFS warehouses.  You would need a script or a tool to clean virtual machines.  There is an example of a very simple script in NetApp TR3428 (http://www.netapp.com/us/library/technical-reports/tr-3428.html), or if you actually NetApp, you can use IVMS (http://www.netapp.com/us/library/technical-reports/tr-3737.html).  These scripts don't rinse apps by themselves, but depending on the application, you can incorporate pre/post scripts in the virtual machine.

• Does anyone have a CONCISE answer to the catastrophe of adobe_flash_setup?

  Unfortunately, I got caught by the Adobe_flash_setup disaster. At the beginning it was not too bad, but now, if I open Firefox with ANY web browser and then simply click on the window of the browser search I had up to nine windows or tabs pop up. I did everything what I found online. I have cleared things out of the registry, I ran all kinds of adware detectors. I finally bought reimage since Mozilla suggested that it was a way to fix it. I paid the money, the program lasted almost half a day and claims to have done a lot of things but, after reinstalled the reimage Windows removed 97 updates, I pulled to the top of Firefox and get always the same shit.

  Inernet Explorer works well on my machine, I have to use Firefox is totally impossible to use at this stage. I hope someone can come up with a REAL answer and send me an email. My next option is to clean the machine, reinstall Windows and start over.

  I'm not familiar with reimage. Who recommended only? Usually, we offer free software solutions here on the forum.

  It sounds as if your system is not clean. You could:

  Without launching Firefox:

  (1) open the Control Panel, uninstall a program. After the loading of the list, click on the column heading "installed on" to group infections, I mean additions by date. This can help the surface elements undisclosed bundle which snuck out with some software, you have agreed to install. Beware of everything that you don't recognize / remember, since malware often uses sounding names important or innocent to discourage you remove. Out as much garbage as possible here.

  (2) supplement to your regular security with several scanning/cleaning tools software listed in our technical support article: Troubleshooting Firefox problems caused by malware. These scanners on request are free and take a long time to run. If they end quickly, especially if they require the payment you have a serious infection. I suggest the specialty forums listed in the article in this case.

  Start Firefox in Mode safe by holding down SHIFT key when starting Firefox. A small dialog box should appear. Click on 'Start mode safe' (not Refresh). Then:

  (3) open Firefox page modules using either:

  • CTRL + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons
  • in the Windows "Run" dialog box, type or paste
    firefox.exe "about:addons"

  In the left column, click on Plugins. Set essential and unrecognized plugins 'never enable '.

  In the left column, click Extensions. So, if in doubt, remove, if possible, extensions not recognized and unwanted.

  Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

  (4) check your Firefox connection settings here:

  "3-bar" menu button (or tools) > Options > advanced > tab mini network > button "settings".

  The default "Use system proxy settings" should follow the settings of IE, but you can also try the 'no proxy '.

  Any improvement?
