Solutions: Help for your hard drive's dirty bit

Q. I went to defrag my computer and this came up: "chkdsk is scheduled to run on volume please run chkdsk/f." I did the run part, and nothing happened. Can you help me get rid of this so that I can do the defrag on my own?

A. What this tells me is that the dirty bit is set for your drive and is not getting reset. Try this: Bring up a command prompt (Start, Run, type CMD and click OK). Type "fsutil dirty query C:" (don't include the quotes) and press Enter. This will query the drive and tell you if the dirty bit is set. Next, type
"chkntfs /x C:" and then reboot. This should solve the problem. If it persists, bring up a command prompt and type "chkdsk /f /r C:" (without the quotes) and press Enter. Reboot.

Q. I have a Hewlett Packard desktop running Windows XP Home Service Pack 2. Lately, every time I turn on the computer I get a message that says: "Unable to start driver for hpoipm07.exe (hpoipm07.exe)" Then there is an "OK" to click on, which makes the error message go away. What does this

A. HPOIPM07 is a component of the drivers for your HP printer. It is not necessary. You can run the Microsoft Configuration Tool (click start, Run, type MSCONFIG and click OK). Click the Startup tab, find HPOIPM07 and uncheck it to prevent it from loading. Another option would be to uninstall the printer, and reinstall using the latest drivers from HP's Web site.

Q. I continually get a message stating the following: "Security Update for Microsoft XML Core Services 4.0 Service Pack 2 (KB936181) cannot be installed." I believe that we uninstalled this program. We have tried to reinstall with no luck. Please advise what the effect is without this program and what we can
do to reinstall it.

A. This is the XML services package used by various applications and there is a security issue that needed to be addressed with this update. Allow the update. People who have experienced the "Cannot be installed" error have had better luck installing the direct update file from You can find it by typing "msxml4-KB936181" in the search field, clicking Go and then clicking the link in the results to bring you to the download page.

Q. I just bought a Dell with Vista Home Premium. From my e-mail I downloaded My Family Tree to a CD-R disc but have been unable to see it. It went into the DVD-RW Drive (E:). I tried opening a folder but still nothing. I have tried three times with new CD-Rs each time, but I still can't see it. On my old Windows 98, I used to put the disc in, download, and I was able to see it on the monitor immediately. What am I doing wrong?

A. Open My Computer and right-click on your DVD-RW drive. Make sure that it is not waiting for you to finalize the write to disc of the files you have placed there. You may want to try using the Mastered format: In the Burn a Disc dialog box that pops up after inserting a blank DVD, Show formatting options. Click Mastered, and then click Next. Then drag the files into the empty disc folder. On the toolbar, click Burn to disc.

  1. South Florida poaches debris pickup trucks once slotted for Tampa, officials say


    TAMPA — A week into the job of picking up an estimated 300,000 cubic yards of Hurricane Irma debris from its streets, Tampa City Hall is finding to its dismay that the challenge is more competitive than expected.

    A city of Tampa truck loaded with debris from Hurricane Irma pulls into a temporary storage yard on N Rome Avenue Friday morning. There, workers from Tetra Tech, the city's debris monitoring contractor, photograph and check the load from an elevated platform to create a record that the city can use later to seek reimbursement from the Federal Emergency Management Agency.

    TAMPA — It's a blink-and-you-miss-it nuance, but in Sunday's opener against Chicago, on their very first defensive snap, the Bucs lined up in a 3-4 defense.

  5. Along the Alafia River, the grateful extend a hand to the Irma-sodden weary (w/video)


    LITHIA — The things that make a house a home dried in the afternoon sun Thursday in a front yard on Williams Street.

    Volunteers from FishHawk Fellowship Church helped Brian Hood (left) clean up debris from his yard in Valrico, Fla. Last week the Alafia River reached a depth of almost 23 feet, about 10 feet above its flood stage. Many homes were damaged, some became uninhabitable. Hood's home is 6 inches above Lithia Pinecrest Road, and did not sustain flood damage, though not all of his neighbors were as lucky.   [MONICA HERNDON   |   Times]
