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.

Uncovering a Virus/Trojan

Paul

Getting done with the first part really got my juices flowing. I was shopping looking and thinking about this next article. I came up to only one option turning this into a 3-5 length post due to all the content that I will have.  So where did we leave off?  Oh that is right figuring out if you have a virus/Trojan.  The instant I made a post about this 12 hours later someone make a comment and here is what he said:

I can’t wait to read part two of this article. I always wondered how you’d know you’re infected if a virus don’t want to be detected and no virus definitions are yet available, because the virus is so new.

Now the truth is anytime a Virus does something it usually leaves a footprint somewhere and somehow.   Even the hardest working hacker can’t plan for all possibilities and that is where we begin.   I have been helping people for a while with viruses and know that no matter how hard the virus tries to hide you can usually find it relatively quickly and easily do to virus check here are the ways I’ve done to figure out if they may or may not have a virus/Trojan.

Now if this is a client’s computer and you don’t want to be rude to the client, there are a few indications of user error and installing a virus.   This is relatively simple, all you do is do a quick inventory of all the start menu programs.  You’d want to look for any P2P file sharing program, If they have Firefox Installed, and if they are using Window Mail and not Thunderbird.   You see 80% to 90% of virus downloaded are installed by the End USER.  They either downloading a game and installing a virus with [ad#ad2-left]a game, or not protecting themselves by using Internet Explorer or Using Windows Mail.  That is usually my first step due to the fact, I’ve got to be diplomatic about finding out about security ways.  Also make sure they are up to date on there Window updates, unless they are using a really old system then you will have to work even harder.  Also you can suspect a virus if the client is talking about having problem with a program recently although this isn’t always true it sometimes is the case due to the fact hackers don’t have a big chance to test these viruses/Trojans out before they set them into the wild.  So there are always going to be unplanned problems associated with them.

After the first initial search of desktop, you should really know the likely hood of a possible virus getting on the system and later we will talk about counter measures to prevent virus attacks in the future.   There are a few places a hacker likes to put commands.   Hackers love to put in the Registry to run a program every time Windows starts.  It usually in:

  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\

Usually 50% to 70% of virus like to make sure the program to runs.  This is a flaw in Windows because hackers can edit this without much effort but there isn’t many places a hacker can go to make sure a program is set to run when you boot.   So this is also a benifit to finding those little programs.

Now just like the Regisitry, Hackers also like to put programs in a few areas on the hard drive.   This is also kinda hard to hide because most of the time these are consider important to the system but if you know what to look for you can pretty much figure out if it is truelly a system file.  These areas of the hard drive are:

  • C:\WINDOWS\System32[ad#ad2-right]

  • C:\WINDOWS

  • %programfiles%\common files\microsoft shared

  • %windir%\temp\

These are just a few but if you look hard enough it can be found most of the time.   Most of the time I use the registry to tell me where these programs are so I can do a further check of the program.  Some of this is not needed with some of the programs that I recommend but this is for those who want to be a through job and make sure the virus is gone.

On my next post we will talk about some good tools for the trade to help get rid of a virus/Trojan.  This little step here is used to  better help identify a virus and also give you chance to google each name on the list of registry and the hard drive  to see if you can identify the virus.
