Solved Disk partitioning and win 95

June 13, 2013 at 07:47:09
Specs: Windows 95, Intel / 8MB
I recently bought an old Compaq Contura 420c, with 8 ΜΒ of ram. The disk has a capacity of just 500 MB. I want to partition my disk, but without destroying the existing installation of Windows 95 A. Does anybody know of any proper partitioning program, capable of being installed on such a machine? Paragon Hard Disk manager ver. 6 installs with faults and finally refuses to work, as does Paragon Partition Manager 2005 (which does not install at all). Any suggestions?

That's odd. I must have forgotten to include the link. Here it is:

http://www.zeleps.com/download.html

I've never tried it and found it with google but it's small enough to fit on a floppy and works with dos and 9X. The main thing in the readme file was it said you couldn't run it from the partition you're trying to resize so you'd have to run it from a floppy unless a second hard drive was connected.

Don't install, use a live CD:

"Don't install, use a live CD:"

I would, but the machine sports no CD-ROM drive! It only has a diskette drive! Any "live" diskette? I would be glad if there was any...

You ARE going to destroy the existing OS installation if you repartition the drive.

Or does the drive have some unallocated space you want to use? You can use FDISK to set up a second drive in that space.

Or are you trying to resize the partition?

Not if you use partition resizing software. Which is what the OP requested and I linked to.

I don't see where he asks specifically for resizing software. That's why I asked. I thought maybe he wasn't clear on what partitioning actually did.

Here's a small resizing program that'll fit on a bootable floppy. Be sure to read the readme.1st file if you use it.

Well, he talks about trying Paragon Hard Disk manage r, and asks about similar "proper partitioning software". Sounds ro me that he knows what he needs? And if it's not, there's no harm in pointing out such software rather than saying that he can't repartition without losing the OS installation.

I see you've edited your OP to account for that possibility.

In # 4 I know I edited 'empty space' to 'unallocated space'. But I honestly can't remember if I added the resizing comment or if it was there originally. If I did edit it in I would have done it within seconds after posting and before you responded. I don't edit in changes or add comments in my postings in response to later postings by others. If I was going to do that I would have edited in the link to resizing software in # 4 instead of as a new posting in # 6.

No, there's no harm in assuming he wants to resize the partition. But regular partitioning/repartitioning and not destroying the OS on the partition--which is what he said he wanted to do--are not compatible goals. I wasn't sure he was clear on that.

ijack:

"http://paud.sourceforge.net/#introduction"

Paud seems good, but on my system it refuses to install and presents a "Kernel panic: Out of memory and no killable processes..." error. Could it be that my system has only 8 MB of RAM? Thanks for the link, however!

DAVEINCAPS:

"Or are you trying to resize the partition?"

You are right - perhaps I should have stated more clearly that I looked for partition resizing software, able to install on an old machine with only 8 MB of RAM - with the goal of not destroying the existing Win 95 installation.

"Here's a small resizing program that'll fit on a bootable floppy. Be sure to read the readme.1st file if you use it".

Do you mean Paud? Or is there some other link you can post?

Thanks everybody for helping!

"That's odd. I must have forgotten to include the link. Here it is:"

Thanks for the link! "Presizer.exe" is a DOS program and promises to do amazing things - in fact, I could not imagine that DOS could go that far, resize partitions without destroying data. I expected somrthing like a windows program! But I like DOS, and tried to use it, first by reading the documentation.

This is where it seems I misunderstood something, which ended in non-bootable Windows...

The program required a full defragmentation of the system to take place from inside Windows. But first, all files on the disk (even system, hidden or unmoveable) should be made able to be moved by the defragmentation program. I entered the following commands from the DOS prompt, as suggested:

attrib -s -h -r \*.* /s
attrib +s +h +r \io.sys

Then, I fully optimised the system by using the Windows 95 defragmentation tool. Everything went O.K.
Presizer documentation stated that after completing the defragmentation process, one could "set file attributes back to normal". I supposed I should enter the opposite commands from the DOS prompt, i.e.:

attrib +s +h +r \*.* /s
attrib -s -h -r \io.sys

I supposed wrong, I assume! System is still able to boot from the hard disk, in command prompt mode, I have access to all my files via DOS, but Windows 95 do not load! I get an error message stating that there is not enough memory... What went wrong? Any suggestions on how I could bring back to life my Win 95 installation? I understand it is entirely my fault...

I don't think you should have run the ATTRIB command prior to defragging. Some files aren't supposed to be moved. It looks like you removed the attributes on all the files and then re-established them for io.sys. There's another system file--msdos.sys--that I don't think can be moved.

Neither should you have done the 'attrib +s +h +r \*.* /s'. That should have set all file as hidden, system and read-only. But I'm not sure you did that because you can see the files when booting to command prompt.

Well anyway, I think you need to locate the msdos.sys file and copy it to a floppy disk or the windows directory or both. Then delete it from its original location. Then boot with a bootdisk that's the same 95 version as is on your computer and run the SYS command. That will copy the dos version of msdos.sys to the correct place. Then you copy the saved win95 version over the dos version and you should be OK.

But first boot to command prompt on the hard drive and type VER and enter and post back what it says. That way we'll know what version you have.

Well, I followed exactly what the documentation of Presizer stated:

"In order to use Partition Resizer to shrink a partition, you'll have to
defragment it first... You will have to move ALL the files to the beginning of the partition
(including unmovable files). To move unmovable files, use ATTRIB to change
their attributes (-s -h -r). When defraging take special care for the unmovable files: They must be moved too, so change their attributes before defraging the disk".

"MSDOS.SYS: This file can be moved or defragmented as any ordinary file".

From the DOS prompt I can see there exists an msdos.sys file in c:\ (root), i.e. where it should be, I think. It has a size of 1.658 B.

Windows version is 4.00.950.
Anyway, I don't care that much about that old Windows installation - it just strikes me something went wrong with the "attrib +s +h +r \*.* /s" command I applied. Prior to this, everything was O.K. - even when I first applied thw the "attrib -s -h -r \*.* /s" command.
I could well reinstall Windows 95 over the old installation - the only problem is that the Compaq Contura 420c does not have a CD-ROM, just a floppy drive! There are also two pcmcia slots, I'll check if DOS recognises cards when inserted.

Some years ago, I had bought the whole series of Windows 95 diskettes - thinking that they are something of a museum item! I never thought I could need them one day. Seems that if DOS doesn't recognise pcmcia, I'll perhaps have to find that old set of diskettes again...

I'll give Presizer and Fdisk a try (Presizer is a complementary program to Fdisk). It is a good opportunity to learn how to resise disks from DOS and experiment a little bit - I bought the Contura cheaply, just for experiments with different operating systems.

Thanks everybody for helping...

It's good that you have the disks then. Sorry the resizing software didn't work out. The "attrib +s +h +r \*.* /s" should have made all the files hidden, system and read only whereas normally only a few files have any of those attributes. If you want to experiment you can do the attrib -s -h -r\*.*/s and attrib +s +h
+r io.sys
again, reboot and see what happens. The memory error message you're getting may mean himem.sys isn't loading. If it's hidden that may be the reason but as I already mentioned, the fact you can see any files doing a DIR means they're not all hidden so I don't know exactly what happened there.

Well, it was that simple... I did what you advised (attrib -s -h - r\*.* /s from the DOS prompt), and, all of a sudden, the system runs smoothly again! Win 95 boots!

I'll now proceed with Presizer and Fdisk, and post the results (hope I'll not mess up everything again, I have never used Fdisk before - nor Presizer, of course)! But I'll first back up everything in a Compact Flash card, using a PCMCIA adaptor...

Thanks!

That's good. Hopefully the resizing works OK. I've never used ATTRIB to reset all the files on a drive. I'm glad it worked out OK.

As long as the resizing goes OK you probably don't need to use FDISK. If resizing for some reason fails then you'd use it to remove the existing partition, recreate a new one and do a fresh install with the disks.

DAVEINCAPS:

Well, I have to. According to Presizer documentation, Presizer is a DOS program only complementary to Fdisk. After one shrinks the original partition, one has to employ good old Fdisk to make the new partition out of the remaining free space.
Anyway, I used Presizer today! With caution, I have to admit - I have some experience from using Windows partition shrinking programs under Windows XP (Paragon Hard Disk manager ver. 6, namely, which I referred to in the OP), with success - but under DOS? No experience at all! Still, everything proceeded smoothly! Presizer, though basically a DOS program, has a minimal graphical interface, and the options it presents are straightforward. I managed to shrink my c:\ partition from 396 MB to 324 MB, without data loss whatsoever! The system (Windows 95) boots normally.
I hope I'll be able to make a d:\ partition with the help of Fdisk. I'll keep posting!

Today was D-day! After having read a lot about using Fdisk, I finally put aside any hesitations and went ahead... Things were easier than I expected, and I easily managed to turn the space freed by Presizer into a brand-new D: partition. My old Compaq Contura now has a C: partition of 324 MB and a D: of 76 MB - and all that without any loss of data! The original installation of Windows 95 (4.00.950) is still there in C:, and runs smoothly!
Wow! I was impressed by the capabilities of Presizer, given it is a DOS program! When I began this thread, I expected to be guided to use some sort of Windows program, I had no idea that DOS applications such as Presizer existed at all... Perhaps I should drop a line about Presizer in the DOS forum!
Thanks, DAVEINCAPS, for suggesting Presizer to me. iJack, thank you too, for suggesting Paud (a "live" Linux diskette, which I will test for sure someday on another system).

Next goal is to install Windows Chicago (a pre-beta of Windows 95) in the new D: partition, and with the help of a boot manager be able to dual-boot the Contura between Windows 95 and Chicago! But that's another story...

Thanks again everybody for helping!
