112329 2003-01-09 03:31:00 Been playing with Linux on an old 486. The hdd had partitions on it created with a dos/win boot disk, I used the Linux version of fdisk to delete these and create new Linux partitions. Now I want to remove this hdd and use it in another machine with dos but dos fdisk gives me this "Error reading fixed disk"message. Any ideas on how to get dos to "see" the hdd??. The hdd works fine with Linux and even doing a zero fill with the hdd maker's utility has not helped.
Thanks

112330 2003-01-09 05:30:00 Umm. Try using the Linux fdisk to remove all linux partitions, then make a DOS one. (I'd trust Linux fdisk to make a DOS partition, rather than trust MS FDISK to handle Linux partitions ... even removing them. :D)

If you are using an old DOS FDISK, it can't cope with non-DOS partitions. :_|

112331 2003-01-09 20:33:00 Have done that with Peanutlinux boot disks - no go, msdos can't see it.
Installed DeLi Linux in console mode, set up lilo and got a no operating system message upon rebooting.
Had a go at installing DR-DOS and it can't see the hard disk either.
The drive will work ok in Linux if I boot of a floppy though.
Bad mbr or boot sector????.

112332 2003-01-09 20:39:00 Are you using a Win98 boot disk, as that would be what I would be inclined to try :-) Chilling_Silence (9)
112333 2003-01-10 02:56:00 What did your disk manufacturer's "zero" programme kill? If you can still use the disk in Linux, after booting with a floppy, try doing "lilo -u" to restore the MBR which existed before Linux was installed on it. That will still have the linux partitions in it (they were made before lilo was run for the first time).

Then use Linux fdisk to delete the Linux partitions (which should stop it working in Linux :D), and make it acceptable to MS. It gets messy, doesn't it?

112334 2003-01-10 03:16:00 A win98 disk wont work I've had a try!!!
Will try the lilo -u think and get back to you.
Thanks

112335 2003-01-10 03:28:00 You can 'wipe' the MBR (and included partition info) with Diskman (http://diskman.no-ip.com/) wuppo (41)
112336 2003-01-10 04:11:00 Well the lilo -u didn't help.....
Having a look at diskman now...
Cheers

112337 2003-01-10 04:15:00 IBM give away a disk zapper. I've posted the address here: a search for "zap.exe" will find it. Graham L (2)
112338 2003-01-10 05:57:00 The same query cropped up a short while ago, and with the popularity of playing with Linux it will continue to arise.
My own solution is to use Partition Magics' dos program pqmagict.exe.

This will remove non-dos partitions and the linux extended partitions that FDISK cant do.

It can in fact be downloaded from the New Jersey Institute of Technology:
