I turned the computer off while we were gone for 3 weeks, and when we came back, trying to boot, it gives the message data error reading drive C:. Once I got the message: missing

or corrupt ifshlp.sys file. I have tried to press F8 and try every option available and keep getting data error. Can not access windows. It gives c prompt, but in trying to copy over another copy of the ifshlp.sys file still get error message.

Any help???? Wayne

This question was answered on July 14, 1999. Much of the information contained herein may have changed since posting.

This information was taken from microsoft website, I hope this should be able to solve your problem

Microsoft Windows 98

Microsoft Windows 95


You may receive one of the following error messages when you are starting or using your computer:

Serious Disk Error Writing Drive <X>

Data Error Reading Drive <X> (where <X> is the drive letter of the drive )

Error Reading Drive <X>

I/O Error

Seek Error - Sector not found


These error messages indicate either damaged data or physical damage on the hard disk


To test the hard disk, run ScanDisk To run ScanDisk from within Windows, follow these steps:

Click Start, point to Programs, point to Accessories, point to System Tools, and then click ScanDisk

Click the drive you want to examine for errors

Click Thorough, and then click Start

Running ScanDisk with the Thorough option selected examines the hard disk for physical damage If damaged data is detected, ScanDisk gives you the option to save the damaged data to a file or to discard the data The ScanDisk surface scan may take a considerable amount of time on large hard disks

To run ScanDisk from a command prompt outside of Windows, follow these steps:

Click the Start button, click Shut Down, click Restart The Computer In MS-DOS Mode, and then click Yes

Type the following command at the command prompt, and then press ENTER

scandisk <x>:

where <x> is the letter of the hard disk you want to check

When ScanDisk finishes its initial check, it prompts you to perform a surface scan on the drive Click Yes or press ENTER

If ScanDisk is unable to repair damaged data, or indicates that the hard disk has physical damage, you may need to have the hard disk checked by a qualified service professional
