Cannot set an installable partition with FDISK

Last Updated: 3rd July, 1997


When Advanced Installation is chosen for the installation of Warp, FDISK thinks that "your partition mapping may be corrupt". Partitions can only be deleted but this won't help. As a result, you can only use Easy Installation and choose the default partition. This may not be what you want.




Partitions on your harddisk (for example Linux' ext2fs) may be misaligned so that it confuses FDISK. This is probably a bug in Warp.

A related (but different) problem might be that you are using a harddisk which is bigger than 4.3 Gb. In that case, you might want to use IBM's updated (E)IDE drivers from the OS/2 Device Driver Pak On-Line.


The FDISK included with OS/2 2.1 (or Warp Beta II) does not have this problem. You can download it from here.

There are at least four possible solutions to this problem.

  1. If you have the floppy version of Warp, backup the disk containing FDISK (Diskette 1). Copy the FDISK of 2.1 onto that disk, replacing Warp's FDISK.



  3. If you have the CD version of Warp, one solution is to make the diskimages from the CD. Execute MAKEDSKS.BAT or MAKEDSKS.CMD on your CD for that. Then proceed as described above. If you're not an expert, this is the way to go. The disadvantage is that you'll need lots of floppies, and installation will take quite some time. If I were you, I would not install all bells and whistles. Once you have a minimal Warp system on your harddisk, you can install other parts directly from the CD. When Selective Install asks for a path (defaults to A:), change that to x:\OS2IMAGE, where x: is the drive letter of your CD-ROM.
  4. If you have the CD version, you could also temporarily copy all the installation files to your harddisk, if you have the diskspace to spare (about 45 Mb). See these instructions for more information on how to do that. Then copy the 2.1 FDISK over the Warp FDISK (in D:\OS2IMAGE\DISK_1) and install from there. After the installation, these files can be deleted.
  5. Probably the easiest solution is the following approach. This one worked for me.


In the end, I borrowed a SCSI tapestreamer, backed up my data and repartitioned the whole disk. FDISK and my harddisk are buddies again...
