Occasionally, when I turn on my computer, I get hard disk controller failure. I've ignored it for about 5 months because when I reboot the machine, everything is fine, no problems. It is getting worse now. I ran Norton disk doctor and it said--Norton disk doctor does not recognize some partition entries on hard disk 1. Back up all partitions on this disk before continuing. You should only continue if you are unable to access a drive you previously were able to access. Would you like NDD to search for dos partitions & rebuild the partition table. I said no for now because I have no idea what is happening. Then it says--unable to continue testing the partition table on hard disk1, it is either empty or contains entries not recognized by NDD. Now, when I run scandisk everything checks out fine. Does ED-BIOS have anything to do with this? I got a new hard drive & dos would not recognize all the space so the technician install ez-bios. Dos still reports the hard drive size as 503M in Microsoft Diagnostics, but in pctools system info it reports it as 850M. Do I need to do delete the partitions & do fdisk & reformat? Also in system info in pctools it reports that the fixed disk controller is ok. This is an IBM clone computer, 80486, 50 mhz. HELP ME UNDERSTAND THIS PLEASE & TELL ME WHAT TO DO TO FIX IT. THANKS

disk scanners sometimes will tell you there's a problem when there isn't... if ndd gives you partition errors and you have no trouble accessing partitions, it's probably not worth the trouble of letting it play to "fix it"... but being that the computer itself gives you an occational hd controller failures, you can be realitively sure that your drive is going bad be sure to back up anything that you can't stand to loose, and start looking for a new drive, it's only a matter of time diagnostics may show nothing wrong until it just out and out dies

I put a boot disk in & rebooted my machine because I noticed when I tried to start pctools diskfix it said you must unload all memory resident programs. Only Central point programs are safe. I first rebooted and hit the shift key when it said starting msdos, and diskfix still wouldn't work. Nothing loaded but ez-bios. I used the boot disk, ez-bios did not load and diskfix started, scanned the drive, & reported no errors. I also did an fdisk /status and it reported disk 1, drive c, Mbytes, the the usage. Can someone tell me how to unload ez-bios so it wont start when I turn on my computer or how to uninstall it. I looked for a line in my autoexec.bat & config.sys but I could not find one. I am still confused about the partition table errors yesterday because today, after I used the bootdisk & started the utilities program, it loaded, & tested the drive fine, whereas when I dont use the boot disk, I get partition errors when I run disk utilities.

if you can find a copy of ezdrive, it can be removed by running it... But with your computer, removing ez bios would result in you being unable to use your hard drive, or at the very best, you could only use the first 540 megs of it almost all 486s had bios's unable to address disk space beyond 540 megs, this is where somehting like ez bios comes in and takes over, allowing access to larger drives it could be overcome by purchasing a 32 bit drive controller, and installing that... but if you don't know how to do it yourself, it may be more bother than it's worth you boot off of a floppy and you scan the drive and it gets no errors? that's good... the best i can say to you is that i once had a drive that disk scanners would give some partition error...but i never had it fix the error b/c i never had any problems accessing the partition....i had that problem for probably 2 years and never had a problem.... i ended up buying a bigger hd, so the old one got formatted anyways, never giving me a problem i don't want to give you a false sense of security, if you can, backing up at least the data that can't be replaced (this may be just a few saved games, documents, and pictures) is important to do, at any time, just not when things become problematic but if i got that error and i had no problems accessing any data, i wouldn't worry about it what kind of a drive is it, anyways?

I recently bought a 20 GB hard disk. I had 4 partitions (c: d: e: f:). I created a new partition of 500 MB and moved my windows swap file to that partition (using PQ magic). Then I installed Linux on my D: with instructing the lilo to be written on a boot disk and not MBR. However later I decided to delete my Linux partition. But I could not start PQ magic. It used to exit saying Init Error #255. I then tried to use fdisk from dos (not windows) and as soon as I typed fdisk the system would hang and then reboot. I then ran Partitioninfo (shipped with PQ magic) and it reported that there were errors in my partition table. I then ran PQ magic under dos and it reported that there was error #140 in my partition table. Although I am able to boot into both Linux (using boot disk) and Windows (Normally), I am not able to run any partition managers i.e fdisk and PQ magic. Please advice.
