1. Is My Hard Drive Failing?
Reader Jerry wrote about a problem he was having when he tried to make a backup image using Acronis True Image...
Terry I want to make a hard drive image for a backup so that when I have to reinstall my windows and programs all I have to do is copy the image to the drive I want to use, what is a good program to use I tried acronis and I couldn’t make it work. It kept saying that certain sectors could not be read so I told it to ignore them (else it would not continue) and when it finished I tried using the drive and it would not boot. I’m using XP.
Jerry
I wrotte to Jerry to tell him thatt if certain sectors of a hard drive can not be read, it sounds like the hard drive is failing.
IDE and SATA hard drives have a number of spare sectors. When the drive's built-in controller recognizes that a sector is going bad, it automatically moves the data from the failing sector to a spare sector. Then, it re-maps its internal tables to point the "sector" to the new, real location on the hard drive.
Based on the error he is seeing, he is not likely to find any image program that will be able to read your bad sectors on the hard drive. The hard drive problem will have to be solved first.
At this point, Jerry had three basic choices:
- get a new hard drive and reinstall everything,
- use Windows own Error-Checking program, which may work, and
- use a program like Steve Gibson's Spinrite 6, which will take hours and hours, but is your best bet for recovering the data in those sectors.
After options 2 or 3, he should be able to back up SOMETHING using Acronis True Image; however, if the recovery program did not recover usable data but did make the sectors readable, then the image will have bad data. In other words, the sector may now be readable, but the data values that are readable may be different than those originally stored there.
Tech Tip
If the data values are readable but are different than those originally stored in the sector, that may be a noticeable problem or it may not be. If the data happened to be part of a .jpg image file, you'd probably never notice. Similarly, if it was part of a .wav or .mp3 file.
However, it the "data" stored there was really part of a program, the program is likely to crash or hang — ultimately requiring reinstallation in order to work properly.
Windows' Error Checking is found by Start > My Computer > Select the drive you want > Right-click on the drive > Properties > Error-Checking
Spinrite 6 is available at www.spinrite.com . You purchase it, download it, and burn it to a CD or write it to a floppy, then boot the CD or floppy.
Jerry wrote back to say:
Thanks Terry for your reply I used the windows error checking program and it fixed the bad sectors and then I was abe to make a image of my hard drive. Should I be concerned about these bad sectors and get a new hard drive?
I wrote back to Jerry to tell him that I would get a new drive at that point. Windows probably marked the sectors as unusable, but that's just the start of issues. There will be more - and they might have important data in them.
Jerry wrote back one more time...
Thanks a lot. I enjoy your news letter

2. The Lighter Side of Technology
This week's technology cartoon at Terry's Computer Tips!
I guess when you do everything with your computer, it just seems natural to use email for an emergency call. I would rather my family use the phone...
3. Scanner Software Requires CD to Run
Reader Mickey Christensen wrote aout problems with his scanner and its software...
Terry,
I have a HP Scanjet 4850 scanner that is a pretty good scanner. The scans are usually clear and the color is good too.
My problem is that when I try to use it, I have to have the program CD in the drive. I have installed and uninstalled the program several times. I have gone out to the HP website and it says there are no updates available.
I can load the program, run it and it runs fine. Then a few days later if I try to use the scanner, I get a message saying Windows is trying to configure Document Viewer.
When I hit the cancel button, it just starts over with trying to configure Document Viewer. I have to go to task manager and end the task.
If I put the CD in the Drive when this message comes up, it will go on and run. The Document Viewer software appears to be in the program folder on my computer, but apparently it can't find it.
I have sent an email to HP and their reply was it was something on my computer (Could be, but I don't know for sure what it is.) and since I was past the 90 days, it would cost me money to get them to help.
I just put the CD in the drive and do what I have to do and then don't worry about trying to use it without the CD.
I wonder if Regcure could be the problem? I have Regcure run periodically to correct other problems I was having.
I am running Windows XP Pro and I think I have installed SP-3 (I know SP-2 is installed).
Do you have any suggestions on how to get the program loaded on the machine so when I click on HP Solution Center I can use the scanner without finding the CD and putting it in the drive?

I wrote back to Mickey to say that I don't think RegCure is causing the problem, at least not directly, but it could be. Registry cleaners go in and delete a bunch of stuff in the registry that isn't internally consistent (as they or Microsoft define it).
It sounds like Mickey has RegCure scheduled to run routinely. I suggested that he stop that for a while and see if that stops the problem.
With the scanner plugged into the wall and into the computer, uninstall all the HP software that applies to it. Be sure to go through Control Panel > Add-Remove Programs and get anything that applied to the scanner.
Unplug the USB connector to the computer from the scanner.
Reboot.
NOW, run RegClean and let it see if it finds anything to handle.
Reboot again.
Check the scanner instructions. HP software normally requires that it be installed before the scanner is connected. At a certain point, the software will tell you to connect the scanner to the computer.
Start installing the scanner software according to the instructions.
When that's complete, make sure that RegCure is no longer scheduled to run automatically.
After a few days/weeks/whatever, you should know if the scanner software works fine. At that point, you can run RegCure again.
Mickey responded:Thanks, I will try that.
I have done all but stop Regcure for several days before. I will do this to check it out.

4. Repartitioning to Make Room for Windows 7
Subscriber Elise wrote this week about changing the layout of her hard drive — like a lot of people, she's thinking about Windows 7 and wants to get an early start with the Release Candidate version from Microsoft:
Terry,
I want to partition my hard drive so I can dual boot between XP and Windows 7. Is there a free software program, that doesn’t require a PHD to operate available?
Thanks,
Elise
I wrote back to Elise that I'm not aware of one. Well, that's really an exaggeration, but they're not for the faint of heart.
GPartEd (http://gparted.sourceforge.net/download.php) is designed to do partitioning and partition resizing, and it's free. No, it doesn't require a PhD, but it isn't completely obvous either - you have to know and understnand what you're doing.
Also, resizing your existing partition to make free space and then creating a second partition for Windows 7 is just the start, if you're trying to make them totally independent. Windows has a bad habit of installing parts of the new OS into the folders of the old OS, even if it's on another partition.
You would also need a partition boot manager that HIDES the partition that is not the currently selected one.
Elise wrote back to me to say:
Thanks, Terry,
I’ve muddled through with Easuse and I’m up and running with both OS’. It was a learning curve but worth the effort.
Thanks again for a great Newsletter. And for responding to me.
Elise
I think Elise meant EASEUS Partition Master 3.5, which is a alternative to Partition Manager (and GPartEd, which I mentioned).
It supports Windows 2000/2003/XP/Vista/2008 server. The Home Edition is free, but limited to 32-bit operating systems. If you have 64-bit Windows, you would need the Professional version.
5. My Computer Security Software Recommendations
I review my security software recommendations and update them for each weekly newsletter issue, if I think they need to change.
My Philosophy: Many people want to pick their most economical solution and prefer an all-in-one anti-virus, anti-spyware and firewall solution. In concept, that's a great idea. In actual practice, I don' think that this type of package is likely to be the best in all the protection categories you need. Other people want to pick the best of each type program. I'm one of the these folks.
My choice of software that I am willing to recommend is driven by my search for software for me to use. I only recommend programs that I like and that I use. I will sometimes suggest alternatives to my recommendations, but I clearly note if I no longer use them.
I'm often asked for alternatives to the programs that I recommend, especially by people who want to buy one package to do everything. My choice of antivirus before I switched to Sunbelt VIPRE was ESET's NOD32, which I used for a number of years. I'm trying ESET Smart Security 4 as such an alternative on my notebook computer (my main computer). Smart Security 4 has gotten great ratings and includes antivirus and antispyware, both from their current NOD32 v4 version, and antispam and firewall. So far, I'm very impressed.
Anti-Virus
I'm often asked about several other popular anti-virus or anti-virus combination packages. Yes, I realize that they are not in my recommendation list. "Enough said..."
From 2003 through mid-2008, my personal choice was ESET's small, fast NOD32 anti-virus program, which offers a FREE 30-day evaluation license. I consider NOD32 one of the best in anti-virus protection — and it continues to get recognition andn awards. Unlike some of its competitors, ESET offers multiple-year licenses also, and includes program updates in the multiple-year license.
Tech Tip
Many antivirus programs will offer you an anti-virus signature subscription renewal when your subscription renews. I strongly recommend against this option — buy the full program or make sure you get program updates with the subscription renewal. Both NOD32 and VIPRE purchases include both program updates/upgrades AND antivirus signature updates.
Vendors routinely improve the capabilities and speed of the programs, too. If you update only the signatures, you miss any program improvements.
However, I've changed from my long-time programs NOD32 (antivirus) and CounterSpy (antispyware) to Sunbelt's new VIPRE Antivirus + Antispyware.
I've found that VIPRE puts even less load on my computer than the speedy combination of NOD32 and CounterSpy. I've also been impressed with the way its "deep scan" has found and eliminated risks that were stored in zip files, which is one of the latest malware email tricks.

Firewall Software
While the Windows XP firewall is much better than no firewall at all, don't count on the Windows XP firewall to meet your needs. You need a two-way firewall, which the Windows XP firewall is not!. Microsoft woke up and supplied a two-way firewall with Windows Vista.
The Windows XP firewall does not control outbound communications originating from your computer — and you should want to have control if adware/trojans/spyware or even commercial products want to talk to the Internet. Whether they are calling home or spewing spam, you want to be able to control your computer.
Do you want Windows Media Player to call home every time you play something? It does! Do you use the Search function in Windows Explorer to find things on your hard drive? Did you know that every time you search, Windows Explorer talks to Microsoft?
I didn't know that when I ran ZoneAlarm, but the Sunbelt Personal Firewall flags that to me, and I can stop it or allow it to happen. Many other programs try to call home when you run them, too.
I recommend my choice for a firewall program, which is Sunbelt Personal Firewall.
You can try the full-featured "paid version" of Sunbelt Personal Firewall free for 30 days — after that, you can register it or, if you're using it on a home non-business computer, you can let it revert to the free, lesser-function license.
Tip: Be sure to read my review of SPF for the settings I recommend.
Sunbelt Personal Firewall is regularly $19.95 (with discounts for multiple computers and/or multiple years!) for a non-expiring license for the program and includes one year of their updates subscription.

Anti-Spyware / Anti-Adware Software
CounterSpy, from Sunbelt Software, has received many kudos from the computer press for its always-running and periodic full system scans. It has been my personal choice for my PC's and my family's PC's.
Sunbelt's CounterSpy v2.5, both improved CounterSpy's performance against malware and reduced its impact on system resources and responsiveness when its scanning.
Sunbelt continues to release updated program versions — the current version is v3.1 — and there's an even newer version about to be released. Nicely, Sunbelt do NOT install the updated programs automatically. You have to use the Update process in the program, which means that you'll know that something significant has changed.
Now, I've changed from my long-time programs NOD32 (antivirus) and CounterSpy (antispyware) to Sunbelt's new VIPRE Antivirus + Antispyware.
I've found that VIPRE puts even less load on my computer than the speedy combination of NOD32 and CounterSpy. My computer seems to have much more pep and power than it had previously. I've also been impressed with the way its "deep scan" has found and eliminated risks that were stored in zip files, which is one of the latest malware email tricks.

Anti-spam Software
In today's Internet world, the question is not "if" you will get spam, but "how much will you get?"
I use and recommend POPFile as my first choice for handling spam. POPFile sits on your computer, between your email program and your ISP mailbox, and handles emial as it downloads.
POPFile uses a different approach to handle spam than some other programs do — it does nothing to reduce spam. It is designed as an email classification tool — you train it to recognize spam and any other type of email that you want to classify. These classifications can help you sort your emails into appropriate folders in your email program.
Sunbelt Software, who makes the anti-spyware program CounterSpy (which I use and recommend) and the firewall that I use and recommend (Sunbelt Personal Firewall) also has a well-regarded, award-winning anti-spam program called iHateSpam for Outlook and Outlook Express. Since I don't use Outlook or Outlook Express for email, I haven't tried iHateSpam.
Mailwasher Pro would be my first choice to handle spam before it ever gets into your computer's Inbox. Mailwasher Pro uses on-line Realtime Black Lists mail servers sending spam recently, "training" by you of what you think is spam, and your own "friends" and "blacklist" lists. Note: I found that PopFile generally meets my needs and stopped using Mailwasher Pro, even though PopFile works AFTER the emails have been downloaded. If I used a dialup connection, I would be more interested in Mailwasher Pro.
Mailwasher Pro can even bounce spam messages, as if your email address was not valid, although the usefulness and appropriateness of this is questionable. There is a free version called "Mailwasher," but it omits the functions that I consider critical for this purpose -- such as safely previewing the emails safely before they ever get to your email inbox.

Cable/DSL Router
If you have a cable modem or a DSL modem, you need to have another layer of inexpensive protection between you and the Internet. A cable/DSL router isolates your computer from direct connection to the Internet. Your computer can easily request your email, web pages, etc. through the router. The responses come back to the router and are smoothly routed to your computer. But, someone on the Internet side of the router can not initiate a connection to your computer — they can only respond to your request.
Even if you only have one computer to connect to your cable or DSL modem, I recommend that you purchase and use a cable/DSL router because of the protection it can give you against attempts to attack through some flaws in Windows itself.
A router isolates your local network, whether it is only one computer or several, from the Internet by actually making it a separate network. The router gets the "public" IP address and handles all your outbound communications and the responses to them. But, it blocks computers on the Internet side from being able to initiate communications with your computer! This will prevent you from falling prey to many worms that try to attack security holes in Windows itself.
For a wireless router, I recommend the Linksys WRT54G wireless router. I'm using the relatively new version 6 of this router.
If you don't want wireless, I recommend the Linksys BEFSR41 wired router, which I also use. Either way, based on my experience, I recommend Linksys routers for price, reliability and Linksys' habit of releasing updated firmware for their products..
Tech Tip
By the way, if you get tempted by the new "802.11n" routers, please pay close attention. So far, the 802.11n specification has not been approved and finalized. IEEE is currently working on Draft 9 of the standard. The final standard is expected to be approved in January 2010.
If you buy one, you may be locked into a specific vendor's implementation of a draft of a standard that never got approved. I recommend choosing 802.11g for now, or recognizing and accepting that you're purchasing a model based on a work-in-progress, and that your router and computer's wireless card may not meet the final standard.
