So I think I'll be leaving EZ-Drive out of the picture on my Librettos in the future if I'm going to continue Ghosting drives here and there.

Or blow off Ghost and use Drive Image. Countless images created on my 4 machines, nary a hiccup.

Hey Lee... When you image a drive, or restore one, do you always use the same method? I.e. always run it within Windows, always drop to DOS and run it, boot from a FD to run it? Or have you used all methods from time to time?


Also, are you running without drive overlay, and have you done any/much partitioning from a boot floppy?

Actually, I've found that once a >8GB HDD is partitioned with other
software, Fdisk can indeed >see<, or report the size of partitions over the
8GB boundary. At least it can when an FAT32 extended partition staddles the

Just guessing here, without looking at the source code :) but I'd venture to suggest that fdisk uses the bios to talk to the disc. Thus, it can read the partition data if it's already been written by a sensible program (as that's early in the disk) and it *could* write oversized partitions, if it wanted to, but it probably checks against the size of bios reported disc size.

Hey Neil.... good to see you still dropping in from time to time!


I just ran a test that shows one good reason for having drive overlay installed on a Libretto. Without EZ-Drive installed, at least FDisk run from a boot FD is able to >report< the size of an extended partition and the logical drives it contains. But Partition Magic booted from a set of FDs doesn't report anything after the 8GB barrier correctly.

Here's what my 40GB HDD looks like with EZ-Drive installed:

C:   Fat32          3GB      Primary
D:   Fat32          5GB      Primary
*    Unallocated    54.9MB   Primary
E:   Fat32          30GB     Primary

Here's what it looks like without EZ-Drive installed:

C:   Fat32          3GB      Primary
D:   Fat32          5GB      Primary
*    Unallocated    54.9MB   Primary
*    Unallocated    47.1MB   Primary
E:   Check failed

These were done on my 70CT w/32MB RAM. The 1st statistics above were from PM run in Windows. The 2nd group with PM run from a boot FD. My 20GB HDD is more dramatic with an extended partition and logical drives from 3GB to 20GB, but I can�t get the 100CT to boot off a PM FD.

From the information on the last 3 items in the 2nd group, it would seem I
may have miscalculated the hibernation area. But the cylinders for the 54.9 unallocated space occupies are:

Cyl 1016, Hd 0, Sect 1 - to - Cyl 1028, Hd 254, Sect 63

So I'm not quite sure why the 47.1MB unallocated space in the 2nd group, though it represents the very beginning of the E: primary partition.

But this seems to show a good reason for having EZ-Drive installed if the HDD ever needs partitioning from a boot FD.
