| I'd use DiskPatch first, as freeware MBRWork is a "do or die"
operation.
I was going to ask why?, but I think I figured it out. MBRWork's Option
1 isn't sufficient to backup the current locations of logical drives
within Extended Partitions, is it? That's because the logical drive
chain is outside track one? It doesn't really sound like MBRWork will
even try to recover logical drives, but only the Extended Partition
itself.
http://www.terabyteunlimited.com/utilities.html MBRWork
Free MBR utility. Below is it's Readme. A good try may be...
(a) Option 7 - Work with multiple hard drives.
Get to HDD in question, the bad one.
(I'm not really sure how it looks/works).
(b) Option 1-- Backup the first track on a hard drive.
Makes a backup of the current MBR & EMBR.
Then, Option 2 can undo all of the following...
(c) Option 3 - Reset the EMBR area to all zeros.
A generally unused area between the MBR & end of first track,
but it can hold a drive overlay or 3rd party boot manager.
(d) Option 4 - Reset the MBR are to all zeros.
This wipes the MBR table holding the dimensions of all partitions
on that drive, if more than one. But it leaves all other drives
intact.
(e) Select option A to recover partition(s).
This generates partition dimensions into the MBR,
getting them somehow from the partition data area itself.
(f) Option 5 - Install standard MBR Code
This will put boot code into the MBR.
........Quote... MBRWork Readme .......
MBRWork - Freeware utility to perform some common and uncommon MBR
and disk functions. Provided As-Is.
It can perform the following:
1 - Backup the first track on a hard drive.
2 - Restore the backup file.
3 - Reset the EMBR area to all zeros.
4 - Reset the MBR are to all zeros.
5 - Install standard MBR Code
6 - Set a partition active (avail on the command line too)
7 - Work with multiple hard drives.
8 - Remove EZ-Drive (You must boot directly to a diskette (by passing
ez-drive)
for this option to show)
9 - Edit MBR partition entry values.
A - If no partitions exist in the MBR and no EMBR exists then this
option
will allow you to recover lost FAT, HPFS, NTFS, and Extened
partitions.
C - Capture up to 64 disk sectors to a file.
R - Restore up to 64 disk sectors from a file. This feature should only
be used by those who completely understand what they are doing!
T - Transfer/Copy sectors from disk to disk. This feature should only
be used by those who completely understand what they are doing!
P - Compare sectors.

Thanks or Good Luck,
There may be humor in this post, and,
Naturally, you will not sue,
should things get worse after this,

| Hello, All!
|
| I used Partition Magic 8.02 to create a new 1GB partition (J
,
taking the
| space from E:. At the end of operation, I received an error that
| "...cross-linked files were found." There was no option other than
to
| continue. PM then called DriverMapper and it seemed to go
smoothly.
|
| On reboot, Windows Explorer shows E: and J: with no labels. When I
click
| on the drives, I get an error that says, "E:\ is not accessible. A
device
| attached to the system is not functioning."
|
| In Device Manager on the Performance tab, it says "Drive E is using
an
| MS-DOS compatibility mode file system."
|
| In DOS, ScanDisk says, "...cannot examine drive E:" I did not try
J:
|
| Also in DOS, FDisk shows E:'s size as it should (10000MB), but
shows
| System "Unknown" (-- it should be FAT32 --) with an 18% Usage --
which is
| about right. FDisk does not show J: at all.
|
| Partition Magic shows E: as it should -- FAT32; (new) Size:
10,001.4MB;
| Used: 1150.5, set as Logical. Drive J: does not appear at all.
What does
| show is 1004.1MB of Unallocated space after E:; this was supposed
to be
| the new J: partition.
|
| Look in the Partition Magic directory tree for partinfo.exe. Open a
DOS
| prompt, CD to that dir, and run
| partinfo partinfo.txt
|
| Open partinfo.txt in notepad and Copy/Paste/Post to this thread.
|
| Don't try to fix E: (or J until you find out what the problem is.
|
| I'm getting too old for this. Here's the file. I'll try to attach
it to my
| post as well; I hope that's not breaking any rules.
|
| No, that's fine. Actually better as attached.
|
| The extended partition chain has a corrupt link in the chain for one.
|
| Assuming all the start sectors LBA values are correct.
|
| The first EMBR/second table entry contains an incorrect value for LBA
"Num sectors"
| (total sectors remaining in the extended partition).
|
| The second EMBR/first table entry contains an incorrect value for LBA
"Num sectors"
| (total in "this" logical drive).
|
| Again, that's assuming the start sector numbers are correct. If math
corrected
| the E: logical drive still may not show. The "E:" boot sector doesn't
show, so may
| also be corrupt, start elsewhere, or DOS/Windows has a problem with
those
| incorrect values.
|
| You could try to correct the values yourself, and see what that does,
or probably
| safer use something like DiskPatch or MBRWork to scan the disk for the
missing
| partitions. I'd use DiskPatch first, as freeware MBRWork is a "do or
die" operation.
| The demo version of DiskPatch is read-only, so won't do any damage.

|
| Your existing partitions probably aren't at too much risk, but you
never know. Back
| up all important data before fixing anything.
