Solved Hdd keeps forgetting os

Specs: windows 95, Intel g5 2ghz / 4gigs
I have this hdd that refuse to remember its operating system. In the past, I was trying to install windows 7 in it. However, after the os have installed and loaded, I decided to shut the computer down properly. Immediately after it shutdown, i turn on the computer and windows 7 is gone. I am now using this hdd to install win95 but as usual, it installs successfully but when it's time to restart to continue setup, all files are gone. It's very strange and I do not know what's wrong.

It is not the hardware issue of my computer. Win 95 ran on my computer when I ran it from the iomega scsi jaz drive. I want to use this old hdd now so that I prevent further damage to the jaz drive catridges

I believe that microsoft released an update to fdisk back in the day. The original fdisk does not recognize full size of hard disks larger than 64 gb.


Correction the 64 gb. applies to windows 98.

You didn't provide any info about the HDD (make/model or capacity) & you didn't list your system specs. Is this what you're working with - Intel g5 2ghz / 4gigs? What's a "G5"? a Power Mac?

Why are you attempting to run Win95 on a modern system? If for some reason you need it, it should be run from a virtual machine within another OS. Either that or it should be installed on an old system with hardware that it officially supported, like a Pentium 233MMX with 256MB RAM.

As for your problem with the HDD, how are you going about the Win7 install? Are you wiping out all exisiting partitions, creating one or more new partitions, then formating using NTFS? Are you doing the patitioning/formating using the Win7 disk or are you using a 3rd party program such as the HDD manufacturer software? Personally, I always use 3rd party software to prevent the hidden 100-200MB system partition from being created.

"I'm not working with a mac, I'm using a pc"

Then don't call it a G5.

Look, my modern computer can run windows 95, I've tried it with the jaz disk. But since they are horribly unreliable, I want to stop using them. I decided to use a ide hdd. This ide hdd has been used to install windows 7 before but it had failed whenever I shut down the computer.

To be simpler, I plug in the hdd, partitioned and formatted using the windows 7 install, I then install the os, it installs successfully and boots. I shut down the computer, turn it back on and windows 7 is gone.

This happened several months back so I have already made a new machine and got a sata hdd instead. I have a scsi jaz drive which I used to experiment with these old operating system such ad dos, windows 3.1 and windows 95. All os from win 1.x to 95 have been proven to be able to run on my computer.

I partition that same 80gb hdd using win 95 fdisk, I did an unconditional format, i ran the installation. Then when I boot it up, all the files are gone. Since this is an ide hdd, I booted to windows 7 to take a look at the ide hdd. The hdd reports it has data but when I open the hdd, no files could be seen. I ran scandisk from win 95 system disk to find out there were lots of file structure errors, wrong size info, and a lot more errors. No bad sectors were found in the surfaces scan.

I do not know what is causing the error. If you will help, I would be very thankful

Ps, it's i5, not g5. I'm sorry for the confusion. For those who says to use emulation, no I do not like it. I can't use my floppy disk and the screen res is so small. It's my personal goal to prove that my computer can run all versions of windows.

You will not gets Windows 95 to install on a modern machine,

When Windows 95 was first released a 300 Mhz CPU was fast. Once CPU speeds got up to 500 Mhz there was a problem

This is because there is a timing loop within the Windows 95 installation that screws up the installation when it is running on a fast machine. The way round the problem was to under-clock the CPU down to 300 - 350 Mhz. Install Wnidiws 95. Install a patch provided by both Intel and AMD. Once the patch was installed you could then re-set the CPU to the faster speed.

You may be able to install Windows 95 on an older computer and transfer the disk to the newer one but not install it on a computer running an i5 CPU providing it is the 32 bit version. Windows 95 contains a lot of 16 bit code and 16 bit code will not run on a 64 bit computer.

You are never going to be able to under-clock a 3Ghz CPU down to 350 Mhz.

Try replacing the IDE cable. It may be loose or bad. It's an 80-wire isn't it? Check that the drive is properly configured in bios setup. If that's not it the drive may just be bad.

There is no issue with the machine. I have ran Windows 95 on this exact same machine before on a Jaz Drive which uses SCSI. I also know how to install the CPU fix and edit the system.ini files to reduce the amout of ram windows 95 can use to 512mb. Ill try replacing the ide cable. But i highly doubt that would be the problem as windows 7 can detect the ide hdd and windows 95 also sees the hdd and installs there.

By the way, if DOS and windows 3.1 can run on my computer, what makes windows 95 unable to run on my computer?

But thanks for the help anyways. Worse case scenario is I will find a 50 pin SCSI HDD

Just a quick update, can not having the ide drivers affect the installation?

I've never had that problem. The OS starts loading before drivers are necessary so lack of drivers shouldn't cause the drive to lose the OS.

I'm going to close this topic. I have discovered it's not the hdd problem, but it's the software. I suspect it's the drivers and not the hdd fault as I can install windows 2000 in this hdd with no problems. I'm sorry for being stubborn. As for windows 95, I will try to find a 50pin scsi hdd. Thanks for all the help.

It didn't hit me when you mentioned it but 9X fdisk won't properly see an 80 gig drive. Maybe that was a factor.

There was a fix to allow '95OSR2 and '98 to deal with larger drives (within reason). Likely it can be found with a little trawling and patience... May even still have a record or three all about it - where/to download/apply it - somewhere. Found this M$ article - which tells "all"... or most of it...

I have windows 95 C. So can I assume this update is already available for my os?

No, the update was for 98. It updated 98 fdisk to the ME version but most of the time we just copied the ME version over the 98 fdisk. Without the update fdisk would see the drive size as the difference between it's actual size and 64 gig. So an 80 gig drive would be seen as about 16 gig.

I was aware of the 32 gig limit with 95 but never used drives that big with it so it was never a problem. I'm not sure now 95 fdisk will treat an 80 gig drive. For best results I think you'd need to make the partitions no greater than 32 gig.

The above M$ kb explains it all - for 95OSR2 and onwards.

There are '98/98SECds about and I suspect 95OSR2 as well... i still have a wee collection "somewhere"...
