Invalid Drive Specification.

The PC is a 486 IBM compatible. I do have Windows 95' I had a power surge. After the power surge I received a DDO Integrity Error. After trying to Ctrl-Alt-Del several times. I would receive the same DDO Integrity Error.  I then utilized a start up disk to boot up the system, afterwards, when typing C: at the A: prompt, I get the Invalid Drive Specification.  I thought about FDisk to see if this would help.  Are there any other options? Can you help me?

Format the drive after performing FDISK. If you already did it, it probably means that you need a new hard disk drive.

first check your cmos setup to see if the drive is able to be autodetected by the bios.
If it is try a low (mid) level format. for me to help you better
we well need the bran name of the drive and it's size .

When looking in the setup, the C drive is there with this information beside it: 225meg/Type25.  Although the information is there, after utilizing the startup disk, at the A: prompt I type C: and enter, I still receive the message invalid drive specification.  When I do a cold boot w/out the startup disk, I still receive the error message: DDO Integrity Error, Ctrl-Alt-Del to reboot. I have not executed FDisk yet.  What should I do?

Make sure your drive specifications are right in the CMOS settings.

Run Fdisk remove all partitions.
Power off the system.
Reboot from the floppy.
Run Fdisk and add create the partition.
Then try to format the drive.
If you still have problems then the drive sounds like it is bad.

does your cmos setup (bios) have an hard drive autodetect feature? If it does ,does it see the drive?

if the bois sees the drive try fdisk . check the partition information.
if your not interested in keeping the data on the drive .you might try ontracks disk manager to low (mid) level format the
drive this will look for bad sectors on the drive and try to repair them .if it can't it will make sure there not used.
most likely the drive has been damaged in some way buy the power
surge .
you will need to take a look (open the case) at the drive and get the bran name to get the correct Ontrack format utility for your drive.
