Many times the hard disk in your computer stops functioning properly after some years. Some part of it may become unreadable. Or you may delete some important data from your hard disk accidentally.
In such cases you can use this useful tool for retrieving your lost data. Recuva is a freeware which can recover objects/files on your computer which are deleted accidentally or by some virus or malware. It can also recover data from your partially corrupted hard disk.
The tool is very easy to use. It’s fully automatic , simply select the directory from which you want to retrieve the data. Rest of the work will be done by Recuva. It will show you all the data which is recoverable and then you can select the data which you want to retrieve.
Recently one of my friend bought 2 GB RAM for his PC. He already had 2GB installed and he added more 2GB to his desktop computer.But his XP showed only 2 GB RAM. This is very common problem.By default Windows XP supports only 2GB of RAM on 32-bit systems.It is fact that 64-bit systems can support 4 GB of RAM .But very few people know that even 32-bit systems can support up to 4GB of RAM.This can be done by enabling the PAE(Physical Address Extension) on your PC.Now a days almost all processors support PAE.
How to enable PAE on XP:
To enable PAE in Windows XP you have to edit the boot.ini file. Open boot.ini file. It will be there in your system drive. Suppose your OS is installed in C drive then go to run and type c:\boot.ini and hit enter.Add “/ PAE” at the end of the file.
It would look something like this:
multi (0) disk (0) rdisk (1) partition (1) \ WINDOWS = “Microsoft Windows XP Professional” / noexecute = OptIn / fastdetect / PAE
Don’t change anything else in boot.ini or your PC will not boot.Just add / PAE at the end of the line.
Now restart your PC and check if your computer is showing 4 GB RAM. To do this right click on My computer and select properties.Click on general tab and see if it is showing 4GB or not. If it shows then it means that you have done everything correctly and you can use complete 4Gb of your RAM.
Enable PAE under Vista:
It is very easy to enable PAE under Vista. Open cmd and type
BCDEdit / set PAE forceenable
Now it should show 4GB of RAM in Vista.
Warning:Use PAE only if you really have 4GB of RAM or your PC may not work properly. Or if you have got some extra money I will recommend you to go for 64-bit system.
Recently when I tried to copy some files to my mmc using card reader it showed me some error saying the disk is write-protected. Remove the write protection or use another disk.
It was working fine before. I have used this card many times before but it never gave any error and suddenly it started showing this error. After going through some forums I came to know that it happens because of write protection notch but there was no such notch or switch on my card.I kept on searching on more forums and after some time I found one solution to this problem. Follow the steps given below if you are also facing the same problem.
Run Registry Editor (regedit).
Navigate to the following registry key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
Right click on control and create new key.
Name it as StorageDevicePolicies . (Copy and paste it from here if possible)
Now click on StorageDevicePolicies and in right side pan right click and select create new dword and name it as WriteProtect.
Double click on it and set its value to 0.
Now restart your machine and try copying some files to your card.
If this thing also doesn’t work then keep your card in card reader, connect it to your PC and then restart your system. I don’t know the logic behind this but It worked for me.
