Windows 7 - Hundreds of NTFS 55 errors on external hd

I hope this is the correct forum to post this? About a week ago, I opened a file that I had been working on the night before and received an error that the file was corrupt. I checked the event viewer and discovered a ton of these NTFS 55 errors. My system had been running fine up to this point.

I tried to run a chkdsk on the external drive and could not get it to run. I finally got it to run while in safe mode. I ran both chkdsk /f & /r to see if it would fix the issues. In fact I ran it several times and once on my internal drive as well. ( Please see the attached results.) I also ran a system health report and everything was good except for the volume E external drive. It had "The Volume Dirty Flag is set on the Disk" error and it advised to run Chkdsk to see if it could be repaired. (see the attached results)

I'm a digital artist and I keep all of my work on this external drive so it gets a lot of use. It's over 4 years old and I figured it was probably on it's last leg. So I backed up all of my doc's to my other external drive and uninstalled the E: drive to see if that would clear up the errors I was getting. I think this issue has snowballed a bit as the event viewer was beginning to show many various errors.

The problem is, once I uninstalled the old E: external drive, several other problems have appeared. I went to check the event viewer, there was a strange font being used and I was unable to read it. I checked in my font folder and got rid of that font and then when I tried to view the event viewer again, I got the snap in error "System.Reflection.TargetInvocationException" and I have been unable to view the details in the event viewer. Also, all of the fonts for my system had gotten really small. I usually keep the font size on the medium size which is 125% of the default. I checked in the display section of the control panel and it shows the 125% box is ticked, but my fonts are so small, I can barely read them. The other thing that has occurred is when I tried to access the internet with my Firefox browser, it would connect, but I could not see any of the type. Everything was black, even all the drop down menu's? Boooo!

I have been researching to try to determine what has caused these issues and have not found a solution. I thought maybe a "restore" to an earlier time before all these issues began might help so I ran a restore back to 7-16-11. It worked, however my issues were not corrected. I also ran an sfc/scannow on my C drive to see if there were any corrupt files on it as well, but it all came out clean. I also ran a full scan to be sure I did not have a virus of some sort and it came out clean as well.

I can't understand what could possibly be causing these strange errors? I correctly uninstalled my external hard drive? So just for giggles, I re-installed my external hard drive just to see what would happen. When I re-booted, my fonts were all restored back to their normal state and I was able to access the internet again with my firefox browser. I still have been unable to access the event viewer though. I'm sure it's probably corrupt.

Can anyone please shed some light and point me in the right direction? I've run into a dead end it seems and if I play with this much longer, I'm sure I will make the snarl much worse. I have a feeling I'm probably going to need to reinstall everything. It's just I have lost a weeks worth of work and if I can get the issues resolved with out a timely reinstall, it would really be helpful.

I have attached copies of the chkdsk, health report, sfc scan and event viewer snap-in error and you can see my system spec's in the signature. Thanks in advance for any help you can provide.

Check the hard drive with the manufacturer's diagnostic tools.

Oh nooo, just lost my entire post. boo!

Thank you so much for the suggestion. Just want to briefly explain what I have done to try and resolve some of the issues.

7-30-11 I did a System Image Backup restore to my internal C: drive. I had tried to run a system image of all the drives, but it would only image my C drive. This really seemed to help. At first blush things looked good, my fonts were restored and was able to use my Firefox browser again. Yea! However, when I opened the Event Viewer, it opened, but was using an odd font and I was still unable to read the error messages.

Did some more research and discovered that my Fonts might be the culprit. I found the main font used by Windows (Segoe UI) was corrupt, it had "0" kb. So I found a good copy and replaced it in my main Windows fonts folder. I also restored the entire folder back to the original fonts that originally came with Windows 7 prof. I was totally surprised and three of the issues I have been having disappeared! Yea! My small fonts in windows were restored to their normal size, I could use my Firefox browser again and the event viewer had returned to normal functioning. Yea!

I found a wonderful free font manager called "NexusFont" I am a digital artist and I have thousands of fonts that needed to be managed. This little app really did the trick and got everything organized and running perfectly! If your ever in need of a good little manager you can find it here: xiles.net - Downloads (NexusFile, NexusFont, NexusImage)

Also if you need to restore your fonts back to their original state, I found this list which shows all the fonts that ship with Windows 7 Fonts supplied with Windows 7

So the good news is 3 issues solved and as a bonus, since I cleaned out my windows font folder, my startup time has been reduced significantly! Yea! However, I still have more to resolve.

I ran Lifeguard's disk diagnostic on my external drive, the extended test, and much to my surprise, it passed? Took it nine hours, but it passed completely. Curious?

I have been reviewing the Event Errors and warnings and I still have some issues that are puzzling. Namely these:

Application Error 1000 - for my Wacom Pen Tablet Ntdll.dll

Side by Side Error 72 - Microsoft Security Client MSEsyss.dll

User Profile service Error 1530 - Registry error showing 6 leaks.

So, here are some questions I have at this point:

1. How do I check to make sure all of my drivers are updated and running properly? Is there a guide of some sort I can use to verify this information?

2. Do I need to run the Lifeguard Diag. short test on my External HD? I previously ran the sfc/scannow thru an elevated command prompt and I was not sure if it actually just checked my C: drive or all of my drives. Is there a way for me to run sfc/scannow on my E: external drive? Any other suggestions to help diagnose my external drive? Good news is, I have not seen a NTFS error yet today. Keeping my fingers cross.

3. I have attached the event error reports that I have received since I did the restore from the system image backup and I attached a new system health report . Still getting that "Dirty Disk" error to run chkdsk on the external drive??

4. Any thoughts on the errors I have mentioned above? I'm thinking the first two may be driver issues? And I'm very puzzled by the User Profile service error? Could that be a permissions error by any chance?

Thanks again for all your help! I will keep researching to see if I can find new info to resolve the remaining issues I have been having. Have a great week!
