Make sure that you are doing a surface scan. You may also want to try the following.


Try editing your scandisk.ini found in your Windows\Command directory. You can specify the number of passes that it does over a sector. I have had a similar problems before and this seemed to do the trick.

Look for this -

NumPasses =  1

 The NumPasses is default 1 I tried 10 and was able find the missing sectors. It does increase the time that takes to finish however.

Use the following switch when using the Custom Settings that you specified in the INI file

SCANDISK /CUSTOM

The INI file pretty much has instructions built into it (How nice)

Hope this helps

Yes, but it will be more accurate in marking the bad sectors. When you force it to pass over a sector several times, it will allow the scandisk mark accurately mark the bad sectors. It does however, take a little longer for the scandisk to run.

Since you stated that the formatting was stopping at 5% , it is important that you have all the bad sectors marked. If it hits a sector that is bad but not marked bad, youcould have some unexpected problems.

I would recommend checking the website of Hard drive manufacturer for a utility that can test the drive and let you know if its bad.

Hope this helps,
Craig

Only a low level format can get rid of recorded bad sector, and it is not recommended on ide drive.

You can use a third-party software like Ontrack Disk Manager.

The problems with reply email signatures

Do you wish that you could place an email signature under a reply? Well, unfortunately, you can't. That great Exchange/Office 365 signature you've created will just appear at the bottom of an email chain. What a pain! Is there really no way to solve this? Well, there might be...

> "i need to format my c partition "

1) Is the C: partition the only one on the drive?

2) What is the drive make/model number?

Regards,
Ralph

I suggest you see
MS-DOS Partitioning Summary

As we don't know how big your HDD is or if it's 95 or 98 or Fat16 or fat31?

You may find the drive is too messed up for a format to work. I seems to me you have a corupted partition and may need to re-partition your drive. Do this as a last result. All data and formats will be lost. Fdisk may be your answer. I have not run Win98 yet but If you have a Windows 95 startup disk Fdisk will be on it. After the partitioning then you will need to reformat..BE CAREFULL IF YOU HAVE A LARGE DRIVE. YOU WILL HAVE TO RUN YOUR HARD DRIVE INSTALLER SOFTWARE TO GET BACK TO FULL CAPACITY.  You problem is more suited to be handled by an experienced hardware specialist. Disk manager,Ezdrive,DrivePro are a few of the softwares that can handle this. Western Digital has a Web site that has FTP to get software for theirs, Quantam also...
Be carefull doing these type of fixes, you can end up buying a new drive or going to the repair shop.
