Default Problem with accessing a partition

While browsing the Partition Magic installation CD-ROM, I found extra
utilities on it. One of them was the ptedit32.exe, i.e., Partition Table
Editor v1.1 of 2002. The nice thing about this editor is that it is still
downloadable from the Internet and its interface is in plain English.

I used it to change my 0Bs to 0Cs, but I failed. To be more precise, I was
able to make such changes with this utility and save them (they even were in
place after rebooting the computer), but everything returned to the previous
situation, as soon, as I opened Partition Magic.

Although your reasoning about my logical partitions seems to be OK, there is
probably another limitation or maybe a deficiency of Partition Magic, which
doesn't allow it. By the way, I found on the Internet an another example of
the similar situation with 2 logical 0B partitions within the ExtenedX
partition (cf. www.goodells.net.multiboot.ptedit.htm).

I'm sure that I didn't make any mistake, so simple this interface was.
Its starting screen displays the master boot sector and master partition
table with its 4 entries and their types (in my case: 1C, 0C, 0F and 00 for
the Win98, WinXP, Extended and Unallocated partitions, respectively).
Clicking on 'Boot Record', displays all the boot record details of the
particular partitions.
Consecutive use of the 'Goto EPBR' option moves to the Extended partition
table with my chained logical volumes as the first entries.
Finally, the 'Set Type' option allows to change the partition type.
I would be grateful for your comments, if the above description is useful
somehow.

Regards,
Andrew

Thanks for your comments and hints.
I'm afraid that it's impossible to make such a conversion in Partition Magic.
I have to apologize for informing you incorrectly about the D: partition.
In fact, both the D: and E: partitions are 0B (Hex).


This sounds like a manifestation of the IO.SYS bug I mentioned. You
have CHS partitions in an LBA type extended partition. This is not
necessarily invalid (although a bit silly) but in your case I'd say it
is actually wrong because they all exceed the 8.4GB barrier.

You could try either a modified IO.SYS or use a disk editor program to
change the partition types from 0x0B to 0x0C.
