1
Identify how you’ll use a pen drive. Typically, they’re used to copy large amounts of data from one computer to another. Note that copying files or folder with your pen drive is comparatively faster.

2
Remember that pen drives are mostly compatible with Windows (ME/2000/XP), Mac OS (8.6 and above) and Linux Kernel (2.4 and above) without drivers.

3
Note that the pen drives have different capacities. Normally, pen drives can hold between 32 MB and 2 GB. Older versions have 64 MB, 128 MB and 256 MB of storage capacity. Most older ones have now been taken off the market by reputed brands. If you want to store regular data files and excel sheets, a 512 MB memory pen drive is ideal. If you want to store video clips, MP3s and other large files, choose one with 1 GB or 2 GB.

4
Check to see if the pen drive you want can be password protected. The latest models can. You can choose to protect specific data within the drive for additional security.

5
Learn more about the features and prices of various pen drives by referring to online buyer’s guides. Browse through reviews and compare prices. Some popular buyer’s guides are NexTag, Windows Marketplace, MySimon and Epinions

6
Browse through blogs and tech discussion forums. These are good avenues for gathering more information on features, trends and other insights on pen drives.

7
Only buy a pen drive after comparing prices in different stores online and offline. Search for online vendors using engines like Google or Yahoo. Browse through popular online stores such as CompUSA, Best Buy and Circuit City

8
Confirm the pen drive’s warranty and guarantee period. Usually, they come with a year’s warranty.

warnings

The rumors of the iPhone Nano is back and this time with the photo of the iPhone Nano case.
iDealsChina who has published the information and rendering of the iPhone Nano case manufactured by a Chinese case manufacturer, XSKN claims that the product will be announced at Macworld San Francisco 2009

iPhone App - Pull My Finger

The Chinese case manufacturer, XSKN are the same folks who had leaked the photos of Apple’s iPhone 3G case with a curved back before it was launched.

iDealsChina has provided few details about iPhone Nano’s specification to back up it claims.
They claim that the new iPhone Nano will be of the same height as iPod Nano and will include “3 sensors, camera, [and a] mirror screen but no 3G.”
iPhone Nano case Though I have always maintained that Apple needs to expand its offering to be a serious player in the mobile space, it seems unlikely that Apple would release an iPhone Nano which would look like the one shown in the photo above.
Here are some of the reasons why I think its unlikely:

  • The so-called iPhone Nano’s screen is too small to use iPhone’s virtual keyboard.
  • It is unlikely that Apple would trust a vendor who had leaked the photos of the iPhone 3G case to give them details of their upcoming product.
  • The smaller screen will have issues for iPhone apps that are currently developed for iPhone’s 3.5 inch screen.

But, it is finally good to see some activity on the rumors leading up to Macworld San Francisco 2009.

This is not the first iPhone Nano rumor, we had got a glimpse of the so-called iPhone Nano UI last year.

What do you think about the latest news about iPhone Nano? Any reason which makes you believe that this is a rumor or photo of the new iPhone Nano?

If your system hangs about 2 or 3 minutes at startup, where you can’t access the Start button or the Taskbar, it may be due to one specific service (Background Intelligent Transfer) running in the background. Microsoft put out a patch for this but it didn’t work for me. Here’s what you do:

1. Click on Start / Run, type ‘msconfig’, then click ‘OK’.
2. Go to the ‘Services’ tab, find the’ Background Intelligent Transfer ‘service, disable it, apply the changes & reboot.

This problem with the Background Intelligent Transfer Service should have been corrected in Windows update Q 314862, part of Service Pack 1.

Prefetch is designed to speed up program launching by preloading programs into memory – not a good idea is memory is in short supply, as it can make programs hang. To disable prefetch:

    1. Click ‘Start’ then ‘Run’ 2. Type in ‘Regedit’ then click ‘Ok’ 3. Navigate to ‘HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters’ 4. Right-click on “EnablePrefetcher” and set the value to ‘0? 5. Reboot.

Although not strictly a performance tweak I love this fix as it makes my machine ‘feel’ faster. I hate the annoying ‘are you sure?’ messages that XP displays, especially if I have to use a laptop touchpad to close them. To remove these messages:

    1. Right-click on the ‘Recycle Bin’ on the desktop and then click ‘Properties’ 2. Clear the ‘Display Delete Confirmation Dialog’ check box and click ‘Ok’If you do accidently delete a file don’t worry as all is not lost. Just go to your Recycle Bin and ‘Restore’ the file.

Some machines suffer from jerky graphics or high CPU usage even when a machine is idle. A possible solution for this, which, can also can help network performance is to:

    1. RightClick ‘My Computer’
    2. Select ‘Manage’
    3. Click on ‘Device Manager’
    4. DoubleClick your network adaptor under ‘Network Adapters’
    5. In the new window, select the ‘Advanced’ tab6. Select ‘Connection Type’ and select the correct type for your card and then Reboot

XP enables DMA for Hard-Drives and CD-Roms by default on most ATA or ATAPI (IDE) devices. However, sometimes computers switch to PIO mode which is slower for data transfer – a typical reason is because of a virus. To ensure that your machine is using DMA:

    1. Open ‘Device Manager’
    2. Double-click ‘IDE ATA/ATAPI Controllers’
    3. Right-click ‘Primary Channel’ and select ‘Properties’ and then ‘Advanced Settings’
    4. In the ‘Current Transfer Mode’ drop-down box, select ‘DMA if Available’ if the current setting is ‘PIO Only’

Free Up Memory in Windows XP

I found this useful app via FixMyXP. ClearMem is an Excellent Tool for speeding up your XP Computer (especially if your system has been on for awhile and you have a lot of applications open). What it does, is it Forces pages out of physical memory and reduces the size of running processes if working sets to a minimum. When you run this tool, the system pauses because of excessive high-priority activity associated with trimming
the working sets. To run this tool, your paging file must be at least as large as physical memory. To check your Paging File:

  1. Go to your control panel, then click on ‘System’, then go to the ‘Advanced’ Tab, and Under ‘Performance’ click ‘Settings’ then the ‘Advanced’ Tab
  2. On the Bottom you should see ‘Virtual Memory’ and a value. This is the value that must be at least as large as how much memory is in your system
  3. If the Virtual Memory Value is smaller than your system memory, click Change and change the Min Virtual Memory to a number that is greater than your total system memory, then click ‘Set’ and Reboot
  4. Once you have rebooted install ClearMem
