Description of problem:
During installation, use fdisk to partition drive sdg, as follows:
start end type
2 - 27 ext2
27 - 91 swap
91 - 1023 ext2
then w - write out the table, then q - finished with fdisk,
The following Error message is displayed:
The partition table on device sdg was unreadable. To create a new partition
it must be initialized, casuing the loss of all DATA on this drive.
Click Yes, and let it continue. Result is one partition of Free space 1-1023.
The bug is : what did fdisk do, and why can't the install process read whatever
it did to the partition table?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot cd1 for install
2. select custom
3. select fdisk, selected sdg
4. delete any previous partitions,
5. add new partitions with layout: 2->27 ext2; 27->91 swap; 91-1023 ext2
6. write partition table, quit
Result: install can not read partition table that fdisk just created
Expected Results: install to be able to use the partition table that was just
created with fdisk.
this was attempted on an ES40 with 7 disk drives.
The other drives had older Linux releases and Tru64 Operation System
Disk druid also fails to read a fresh disk label - on a ds10l, using fdisk to
partition the disk (/boot, swap, /) without toggling a file system type, write
the label and then continue the install - disk druid shows that the disk as
free space. (no partitions) Go back to fdisk and toggle the files systems to
ext2, swap and ext2 - then disk druid shows the partitions (although as

I tried to debug this and could see parted reading zeroes where magic
numbers were expected. It could be a problem with fdisk, among other
things (See 60004.)
I think this one is fixed
But it works for *me*
Can someone recheck this with one of the more current ISO sets please?
