Assuming your are using XP, from the start menu, click on run, type cmd and then ht enter.

In the command window type: chkdsk /f /r c:

Where c: is the drive you want to check.

the /f instructs windows to force closed open handles; the /r instructs windows to relocate bad sectors it cannot fix.

Since you are checking C: windows will want to schedule a restart as some open handles cannot be close while using windows.

Let me know your results and if you need further instructions.

Reformatted w2060, assuming that the recovery disk would work. now i keep getting ghosterr.txt error at barely 3% recovery. cleaned cd. no use. "chatted" with bangalor...i mean...

I'm assuming that you formatted your drive because you were experiencing problems. I would suspect that you have some bad sectors on your hard drive. Those bad sectors may have been causing your initial problems as well.

Without replacing the drive, I would recommend downloading a copy of UltimateBootCD (link below). Burn and boot off of that CD and run Darik's Boot and Nuke under HDD. This will write zero's onto all sectors of your drive.

If you can identify the manufacturer of your drive, you can boot off the UBCD and run the manufacturer's diagnostic tools. These will typically include a surface scan which will check for bad sectors and prevent the drive from using them.

If you have a significant number of bad sectors, there may be an ongoing problem. After a while, the drive will become completely useless. If that is the case, you'll need to replace the drive.

Ultimate Boot CD site:

Good luck!

How to use the disk error checking utility...

As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.If you use your computer daily, you should run this utility once a week to help prevent data loss.

  1. Close all open files.
  2. Click Start, and then click My Computer.
  3. In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
  4. In the Properties dialog box, click the Tools tab.
  5. Click the Check Now button.
  6. In the Check Disk dialog box (called Error-checking in Windows 7), select the Scan for and attempt recovery of bad sectors check box, and then click Start.
  • If bad sectors are found, choose to fix them.
  • Tip: Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.

    Bad sectors

    A hard drive contains platters that are magnetic media capable of having the magnetic state of areas on them changed and having this magnetic state retained/maintained. Data is held on a hard drive by representing it in binary form (1s an 0s). The way these 1s and 0s are physically represented on a drive's platter(s) is by having areas (spots) that are magnetically charged or not. The 1's are represented by charged (positive and negative) areas, the 0s are represented by uncharged areas (there is a level of tolerance by which an area is deemed charged or not). When a sector becomes "bad", or is deemed to be so, it is because areas within it no longer appear to be able to maintain a sufficiently magnetized (positive or negative) state (charge) to represent the 1's data in those areas. Bad sectors are marked (flagged) in a table and, when possible, remapped to one of series of spare sectors all hard drives have.

    Now, sometimes an area is deemed (flagged) as bad when it may in fact not really be. Perhaps some oddity during the write process caused the spot to be too weakly charged (which really shouldn't happen or at least not often as that is a sign of another problem), rather than it being a case of the actual area on the media being bad in some way. Using the appropriate utility a sector previously marked as bad can be un-marked (taken off the bad list). And you can use one of these utilities to put a sector back in service (so to speak). Nothing is "fixed", just made available for use again as is.

    However, if a sector really is bad, really can't be reliably, sufficiently charged or made to hold a charge, then it cannot be fixed by software such as HDD Regenerator seems to claim. The only fixing that might be possible would require a lab/factory. A truely bad sector has some form of damage, its physical properties have changed. Software can't undo this. About the only thing that could/can be done through software is to allow that area of data to be read (recovered) where it otherwise may not be by other software.

    You can try the hdd manufactors zero write program. The fdisk and format the drive.
    Then using a 98boot disk with scandisk on it, run scandisk /surface on the drive. And if all those bad cluster show up again. It is hdd replacement time.

    By the way a note of caution, doing that will remove everything, I mean everything from that drive. It will be a 100% lose.

    Another thing is go to and look at the SpinRite product.

    try scandisk from your pc. bad secotors are a sigh that your hard drive is going out. I would not use a hard drive that reads bad secotors. scan it first with AVG its free.

    Bad sactor

    a low level format could revive the disk - download the disk utility from the disk website (e.g if it is a quantum load the disk manager from quantum site & run on the disk - follow screen instructions)
    hope this helps
