No fixed disk detected

By Lakota Tech ·
I have a pc, at startup, does not recognize the c: drive. Instead I get three examples of why the c: drive is not detected. 1. There is no FAT32 or FAT16 partition - recommends Fdisk. 2. The user was using a 3rd party partitioning software..etc. 3. Some viruses cause the c: to go undetected. I tried booting from a startup disk to no avail...all I get is the A. I asked the individual if they tried partitioning their c: (thinking they may have partitioned the entire drive), they claim theydon't know what that means. They want me to format and do a clean install of the OS. BUT, I can't get passed the A and I always get the "no fixed disk detected"...what do I do now? Can this hard drive be saved?

No fixed disk detected

by maxwell edison In reply to No fixed disk detected

The first thing to do is to go into the BIOS and "detect" the hard drive(s). Most BIOSes have an "auto-detect" feature that makes it very simple. If the BIOS can't find that the drive is physically there, open the case and make sure the ribbon cabledidn't come loose. If the BIOS does not detect it, AND the cable is fine, you may have a drive that just failed.

If the BIOS DOES detect the presence of a drive, something else apparently deleted the partition(s). There are some third party software programs that could assist you in that regard. But if it was mine, I'd start from scratch, repartition, reformat & reload the OS. (Because once a disk partition gets "wierd", the whole system usually becomes rather unstable. I wouldn't trust it.)

Good luck,

Maxwell

The harddrive must first be detected by the BIOS. During bootup go to the BIOS menu (usually del-key or F1-key) and choose auto-detect the harddrive from the menu. If this is not an option you have to feed the number of cylinders and sectors manually and therefore have to know what the right settings are for this drive.

Assuming that the system was working fine before it started this behavior, a harddisk failure is the prime suspect. Open the case and verify that the power and data cables are properly connected to the drive and the motherboard. Next, verify that the jumpers on the drive are set correctly. If the harddisk is the only drive on its channel, then it must be set to MASTER (or SINGLE is the drive is a Western Digital.) If there is another drive or CD-ROM on the same channel, that device mustbe set to SLAVE and the booting harddisk must be the MASTER. When you apply power, listen closely to the drive to make sure that is is spinning up. It should make a sound like a jet engine revving up (just a little quieter.)
If the drive spins, enter the CMOS Setup and have the system auto-recognize the drive. If it does, let it set the parameters. (If it doesn't, the drive has probably failed.) If the parameters set agree with the size of the harddisk, then run FDISK. (If the parameters do not agree with the drive, then you migt need an overlay program such as EZ-BIOS.) If FDISK cannot see the drive, it is probably bad. If FDISK sees the drive, choose the 4th option. If there are partitions shown, see if they agree with the size of the drive. Also, if you see only non-DOS partition(s), then the drive was probably using an overlay such as EZ-BIOS. If there are no partitions set, press ESC and try setting one using the 1st option. If that works, exit FDISK and format the partition and install your Windows. Good luck.

I was able to follow your advice almost to a 'T'. I set the auto-detect in BIOS setup first and then made sure the HD and CDROM were set as you recommended (master/slave), I was very much relieved when I was finally able to see the FDISK menu. Thanks a bunch!!

Lets use some logic... If the HD is dead the nothing form above is going to even get close.. When you power on the PC can you hear the HD spin and the heads seek cylinder zero? If you don't hear the HD spin when you power on the PC more than likely the HD is DEAD.. Replace it and the begin to initalize the new HD..

Simple Deduction.. Good Luck.

FYI.. If you are not familure with what a HD sounds like when it spins up.. Go to a working system shut it down. Place you ear next to the system and power it on. You will hear fans running and also a slight sing&chatter for the hard drive. This will tell you that the HD at least did spin up.
