Warning Signs of Hard Drive Trouble

Paul

For every computer there comes a time when you have a problem with hardware or software. This is for those who want to learn the signs of possible fixes for having hard drive problems. Although if you know you’re hard drive is dieing then you better back it up as quickly as possible. You will of course need to get the back up software to protect your data.  If you have special drivers you will need to backup yours drivers.  If you have an OEM system then you will need to backup the Hidden Partition.

So what are the warning signs of a hard drive failure:

    [ad#ad2-right]

  • Unexpected freezing of Windows — When Windows Locks up and you have to reboot or getting a Blue Screen of Death.   You have no choice but to restart because you can’t do anything with windows.

  • Losing data files — if you seem to see files being lost or deleted without your direct input.  It might be a sign of a computer virus or it could be a damaged hard drive.

  • Locking up during boot — this is most common when you have a hard drive failure, although if you can restart and not be a problem then just keep in mind that it might be the beginning.  The more frequent you have the lockup boot problems the more chance of the hard drive dieing.

  • Hard drive isn’t recognized in BIOS– Although this can be a old hard drive, if the bios can’t see it then the problem might be a hard drive failure, usually this is meaning you just have to replace the hard drive.  there’s isn’t much you can do with this problem, just replace the hard drive.  Most of the time it is a problem inside the Hard drive bios and you really can’t fix this, you’d have to send it off to possibly save the hard drive data.

  • Clicking, Scratching, Whirling, Grinding sounds from Hard drive — This is the most dangerous signs of hard drive failure and means you need to get your data off ASAP.  If you want to hear some of the waring sounds of a dieing hard drive click here.

Although some of these can or can not be a hard drive failure, some can be driver issure or disk defragmentation and should be check out to rule out these problems.   There can be several problems that might be easily fixed.  If you think it is a failure you might try Spinrite.  The program is made by Steve Gibson and he actually has a “Absolute Satisfaction Guarantee“.  So if it doesn’t work or your not satisfied you aren’t out any money.  I’ve used this in the past for hard drives that are dieing so I could get all the important data off before it died all together.  It is essential that if you can get it working for a short time to get a backup.

Disclaimer: Although spinrite might fix some of the problems associated with a hard drive failure, it might not fix all the problems or any problems.   So it is left up to the user to decide if it is worth it or not to buy it.   I don’t recommend this for every situation or every problem only for the off chance that it might let you get the important data off the computer before you lose it.  Use at your own risk.

Disaster preparation 101 — Data backup

Paul

In this one I will talk about Disaster, it happens to all of us from time to time. A fire, a earthquake, a stolen laptop or any number of ways. So what happens to your data, is it stored on the laptop? Is it important very sensitive data? Could you get fired if you lost that data?

[ad#ad2-right]These are all questions you must ask yourself when you have laptop. How do you backup your data or even do you have a backup? Having seen this with my own clients, I must wonder if there are people out there who just don’t care. I had a client the other day who gotten a virus and this was a really mean virus. Deleted some very important files when you tried to clean the virus out. She called me in a panic because she couldn’t load up windows? I asked if she had any backups, she said “what’s a backup” . So I sat there discussing this with the client for over 20 minutes. Finally she started to understand, she said she had the OEM Backup DVD but nothing else. She also said she needed help with getting data off the computer. I told her that I would be able to come the next day and I was lucky the virus didn’t do anything else to her data. We were able to retrieve the data from her system. That is where I start my rant , Why would anyone not have backup of there most important data?

So How do you backup your data? This is controversial and somewhat depends on how much people want to spend to keep there data safe and not loose pictures or music. There are several ways to do it, each way has it’s pitfalls or short comings and requires a little more effort:

Kinds of Backup

Hard Medium – DVD, CD, External Hard drive

Although,  The hard medium is usually used that doesn’t mean you can have a backup other than hard.   Here are some ways to back up on the internet.

Internet Medium:

  • Jungle Disk — Provides online storage through the Amazon s3 service.   Only pay for what you use.   It works well with most Operating system.  I’ve used it on Vista so it is really nice.

  • Carbonite Online backup –Another good Online storage.

  • Some Other Online backup — Here a list from Amazon to better help you find the type of software that you might need.

These are just a few options, if you want to look for other you can.  The important thing to do is BACKUP because if you need some data that gets wiped or destroyed.  You will be kicking yourself for not backing up.

What is a Virus and Why do I have one

Paul2 Replies

After seeing more and more the updates coming from the net.  I wanted to talk about what a Computer Virus or Trojan is and how you get it.   So how did  you could of gotten a Virus in the first place.   So here are some information to consider:

The vulnerability of operating systems to viruses

So what does that mean to you?  Most of the times when you get a virus you have a vulnerability in some place in your Operating system and it is either something that has not be known by Microsoft, Apple, and Linux or is know as a Zero-day Exploit. [ad#ad2-right]

A zero-day (or zero-hour) attack or threat is a computer threat that tries to exploit unknown, undisclosed or patchfree computer application vulnerabilities. The term Zero Day is also used to describe unknown or Zero day viruses.

[Via Wikipedia]

This is one of the most used because if it is an unknown exploit by the Operating System creators then they have a longer to us the exploit.  Most of the time hackers like to use this because that means there is a possibility of finding even more vectors to infect other systems.  You see if they can get on one system they can then find ways to get on other systems.

In the Old days, you’d ask

How Did I Get This Virus, Anyway?

You get a virus when you copy infected files to your computer, then activate the code inside by running the infected application or opening an infected document. How you copy the infected files is irrelevant: Viruses don’t care if you get them as an e-mail attachment, a download, or via a shared floppy disk, though e-mail attachments are the most prevalent (and easiest) mode of transport.

[via PcWorld] (Dated Oct 13, 2000 11:00 pm)

That was before hackers wanted to infect for more personal gains.   There is a list of things that hackers want to get when they Infect a system and it is usually very few things.   In the Old days they wanted the fame but now they want money and to take control over the internet.  They usually want to infect for Money or to have computers become botnets.  Now We aren’t talking about the Movie, I Robot.   Once a system becomes a bot it doesn’t think for itself but follows a line of command from the Command and Control center.  So lets say we have  several hundred bots on one net, and the hacker blacked mailed a server saying if they didn’t pay up they’d get DoS attacked.  With enough bots going to one site at one time can slow or even bring down a site, that is how A hacker sometimes uses a virus or trojan to get into a system.

Viruses & Trojans try to Avoid detection

So you have a virus, it wouldn’t do a virus any good to be detected right after getting onto a system.   More and more, viruses are trying to avoid being seen and heard.  Most hackers who program are wanting to infect more than one system so they have to make really sure that you don’t find out your infected.    So with that said there are several ways  and I won’t try to explain them because I think the link talks about it better than I could.   It however will give people something to think about.

In the next few days there will be another post on How you will be able to figure out if you have a virus.  I had to talk about this first so people could understand how to figure out if you have in the next post.  So stay tuned for more

Stop botnets in its tracks With a Firewall!

Paul3 Replies

According to PC World and I’ll quote:

According to FireEye chief scientist Stuart Staniford, detection rates are so poor that, on average, only around 40 percent of security software can detect binaries during the period of greatest infectivity and danger, namely the first few days after a particular variant starts being used by botnet builders.

[via PC World]

[ad#ad2-left]Now let’s talk about this, having been seeing recent surges of people getting infected.  I’ve come to the conclusion that companies like AVG and other Anti-Virus companies are keeping up.   Now true if all you have is an Anti-virus and nothing else that greatly increases your likely hood of getting a virus.

In a recent virus storm, We have people finding my site because of a Good Firewall.   No if he didn’t have anything but Windows firewall then it would of gotten through and you would not of known about it.  So let’s talk about how to prevent botnet attacks.   This is relatively easy and if you follow some common rules.   You to could be less likely to be infected.  I will say this most people don’t do these common tips and they should do them.

[ad#digg-right]So what should you do to help prevent from getting a Virus or Malware.  This is really simple, you want to find an Anti-virus Software that you like, and Firewall that you like also.  You’ll also want to download the tools to better help you in case you do get infected.  Some of these tools I recommend are Hijackthis, Spybot Search and Destroy, Hitman Pro, and Ad-aware 2007 Edition (FREE).  Then Go buy a Sandisk USB memory Stick and put those on there for later use!!  You will always want to keep a backup of those just in case you get infected.

[ad#ad2-right]Make sure you update Windows regularly.  Having seen this time and time again, if you don’t keep windows updated then you lose the battle.  If you have a system that needs updating, I suggest downloading the Clone to Autopatcher.  This little program will download the files needed to update your system without having to be online.  Although, you can have windows update automatically every month but that might not update the recommended updates only the ones that are hot.  It doesn’t matter which way you prefer to update, as long as you do to update regularly, Like every 2nd Tuesday of the Month.

One last tip you should also keep your Firewall and Anti-virus updated.  There is a little program that will do that, it’s call AppSnap.  If you follow all these recommendations you will greatly reduce your chances of getting a virus on your system.
