To change the User Agent string, just enter about:config as an address in the address bar of FireFox, the location where you normally enter a URL (link). I recommend to preserve the original value, which you can get when you enter just about: in the address bar.

Now press the right mouse button to get the context menu and select “String” from the menu entry “New”. Enter the preference name “general.useragent.override”, without the quotes. Next, enter the new User Agent value you want Mozilla Firefox to use. I added my name and a link to my web site to the original value. You can also pick one from the list of User Agent strings. Check the new value by entering about: in the address bar.

The script displays a “.” for each good link and displays the error code and message for each bad link.

Then, to be able to record both the microphone input and the sound card output at the same time using Audacity, you have to un-mute the microphone playback in the Volume control.

1. Double click the speaker in the System Tray
2. Click Options – Properties – Playback – Check Microphone – Click OK
3. Un-check the microphones mute and raise the volume

You should now be able to hear yourself in the speakers or earphone when you talk in the microphone and also be able to record the output (person you called) and the input (you) in Audacity. Select Stereo Mix on Audacity’s Mixer Toolbar and hit Record.

It seems to be a generic hardware failure error message. Here is a “summary” of what I found (Mostly from this website). I found out my problem to be with my wireless network which had too many bad packets, but there seem to be many possible causes. Jump to the solutions.

Disclaimer: I didn’t try all possible solutions, some may not work or may break something.. be careful with what you modify..!

Here are some error messages that also seem to be related to the same problem:

• “Cannot copy: Path is too deep.”
• “File creation error – The semaphore timeout period has expired.”
• “The network path is no longer valid”
• “The request could not be performed because of an I/O device error”
• “The specified name is no longer available”
• MAC ERROR “The Finder cannot complete the operation because some data in \ could not be read or written.”
• “Windows was unable to save all the data for the file drive:\\directory. The data has been lost. this error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.”

Possible Solutions

Most Popular Solutions:

• Changed duplex settings from auto to full (100 or 10 depending on network settings) and now everything works just fine – >Go to DEVICE MANAGER, then NETWORK ADAPTER, right click go to PROPERTIES, go to the ADVANCED tab, then SPEED AND DUPLEX, change this setting from auto to either 10MB Full or 100MB Full (depending on your network).
• I swapped USB ports – sorted!
• I found that unregistering MS’s AVI preview dll (shmedia.dll; see http://www.tweakxp.com/tweak2123.aspx, http://www.tweakxp.com/article36849.aspx) (which tries to preview / read tech data for all avi files, regardless if they’re 700MB +) fixed it.
• Sysadmins found network card on original server was dropping connections every 5 minutes or so
• Robocopy (Robust Copy) or TotalCopy from nethorror-> it is more persistent, and is more forgiving of timeouts and doesn’t throw in the towel after a few retries

• Log to the other server and moved the files from there

When can you get this error message ?

• The most common event causing this error seems to be when you are copying large files over a network (small files usually copy fine) or when trying to copy from an internal hard-drive to a
  USB device (another HD, mp3 player, flash drive, etc..).
• Sometimes even a small file is causing the error
• Copy from computer #1 to computer #2 gives the error but can copy without any problem from computer #2 to computer #1.
• If on a second computer I continuously ping the wireless computer even during the exact times the errors occur, I never get a timeout, and never get anything other than normal ping times.
• The wireless connection when trying to copy large files works about 1 in 3 times according to some
• Copy to external PCIMI network card with 8139 Chip Module (to try: upgrade driver)
• Copy from one internal HD to another (no network involved) and the cables are new
• Wireless or Ethernet – connected to the office LAN over PPTP VPN, I can’t copy even a 10 K file.
• Copy files to Server 2000 server and Server 2003 servers from XP machines
• From USB drive to a folder
• Accessing a 2-gig USB hard drive. I have tried it on 2 different computers and I get a semaphore timeout.
• Backup SCSI HDD onto the primary IDE disk.
• SCSI HDD to the primary IDE HDD
• From a removable bay drive to a new 160gb drive
• I changed the wired hub to a 100Mb switch
• My path is no longer than 30 characters long. That goes for each file. Each file ranges between 4G to 14G
• PCMCIA adaptor Not working, USB OK
• two machines are looking at the same network share, and user A creates a file in that share, but user B can’t see it until they refresh the folder. Try to copy between these folders, and the “Path too deep” error occurs

Possible Causes

• copy from NTFS to FAT32
• Also every time explorer would hang if i disconnected failing drive’s usb cable it would come right back instantly under control then i’d try again with same problem coming back after a few seconds of transfer.
• the network trunking connecting the site switches was at fault
• The problem definitely seems to be network related but only triggered using certain files.
• can rule out any bad computer IO because this will happen from- and to various different PC’s
• The failing save showed TCP Checksum errors. Also reported SMB errors, which would be expected it there are errors lower in the stack.
• I swapped it for an 80 conductor cable, and the DMA mode bumped up to Mode 5 (had old 40 conductor and DMA Mode 2)
• hardware failure, corrupted data or too slow connection
• If you ignore, move past the currently offending file, or other some such, the next copy operation seems to happen without a sneeze
• chkdsk /f/r The disk does not have enough space to replace bad clusters detected in file 38 of name . OR An Unspecified error occurred.
• Yeah, it was the IDE cable for me, or else the Promise IDE card.
• Replaced the Linksys Wireless router with an old DLink and it works fine.
• Bad HD Cable
• Bad Network cable
• *occurred with a large file copy (linux-kernel.tar 125MB) *does not occur with a tiny 1k file.
• It’s your network. Update your drivers, etc. Could be router issues too but less likely.
• It’s your network layer. Think about it…did you ever get it copying within your own HD?
• Make sure all your BIOS’es are up to date, make sure the HDDs do not have bad sectors on them.
• changes on the network

Prevention

1. Keep Windows up-to-date, check for updates at least once a week using windows update, or even better set Windows Update to be launched automatically everyday
2. Use a firewall preferably with stateful packet inspection, like the one included with Windows XP, ZoneAlarm (Free) or Kerio Winroute Firewall 6 which is a 30 shareware trial.
3. Use 2 or 3 Spyware removal utilities such as (because none of them can catch them all):
   • Windows Defender Beta (Free)
   • Spybot Search and Destroy (Free)
   • Adaware (Free)
4. Use an antivirus and keep the virus definition database updated.
   • AVG Free Edition
   • Trendmicro Online Virus Scan
   • Penda Software Online Virus Scan
5. Get Firefox to browse the web along with flashblock and adblock extensions to block most of the ads and popups if you wish.
6. *Be very careful with this* Stop any Windows Services you don’t use (but don’t stop any that you aren’t 115% sure what they do, some are required for your computer to work). See : Windows XP Service Configuration
7. Never execute a file you don’t expect to receive (ie, by E-mail)
8. Nothing is free (generally), so don’t accept any deals, softwares or offers that feels too good to be true, they aren’t
9. Don’t read SPAM E-mails (they can contain viruses or spywares)

Detecting presence of badware (spyware, malware and such)

1. Many popup windows when Windows starts or when you browse the web
2. New search bar in Internet Explorer
3. Can’t change your browser homepage (browser hijacking)
4. Your computer gets very slow or gives you error messages
5. Check running programs and verify if they are bad
   • Using Process explorer, you can see all running programs and processes.
   • Then go to Task List Programs or
     Windows Process Library and make sure all programs are
     good and supposed to be running. If you can’t find a process, use Google, you should be able to find some information about it.
   • Then right click on the bad process and Kill it (that doesn’t remove the spyware, it just stop it for now.)
