Stop Error 7b

By techrepublic ·
I have a 114 gig disk, that used to run Windows 2000 perfectly.

This disk had two partitions: a 44 gig system partition, and a 70 gig data partition.

I wanted the 44 gig system ntfs partition to use the full 114 gig, so I emptied the 70 gig partition and tried to resize it.

First, in Win2k disk manager, I "upgraded to dynamic disk" and tried to resize the partition in Windows Disk Manager. This didn't work.

Then, I downloaded and created a linux systemrescuecd-x86-0.2.13.iso. I ran run_qtparted and resized the NTFS partition. It worked, now the partition is one 114 gig partition with all my boot data intact (I believe this because I can see it when I boot my Win2000 install cd in recovery mode.)

My problem is now this: I get a Stop Error 7b whenever I try to boot. It goes through little ascii bar, then the win2k starting up graphic with the slider, but stops just before showing the desktop.

*** STOP: 0x0000007B (0x82A71A48, 0xC0000010, 0x00000000, 0x00000000)
INACCESSIBLE_BOOT_DEVICE
...
Refer to your Getting Started manual for more information on troubleshooting Stop errors.

So, I feel kind of stupid for using a Linux partition resizer on my Win2k box (instead of finding a copy of partition magic) but what's done is done.

Below are all my notes from debugging this problem. 1/2 in Linux, 1/2 in Windows. Any ideas or suggestions?

The data on the NTFS partition is 1) intact, and 2) important, so what I really want is to fix the drive so it boots.

Thanks in advance,

Mike

Partition Magic's Rescue disks don't work. They boot ok, but complain:

"Error #91: Disk Manager has been detected on drive 1, but Disk Manager is not running. If you are booting from a floppy, remove the floppy disk and reboot. Press and hold the <SPACE BAR> key as your computer restarts. When prompted insert your boot floppy and continue booting."

I am using a USB floppy drive, and my bios is configured to boot from USB floppy. I may or may not have installed partition magic on the computer prior to this problem.

is all the stuff on there really really important cuz I think that you'll need to do a clean install if a repair doesn't work.

Note on Partition Commander 8.0. It doesn't like NTFS dynamic disks. Sees em as a Unix format and not NTFS. Also if there isn't any free space on the disk, it won't resize period. It needs freespace to move files back and forth as it resizes the drives. I tried to resize the system partiton on my home computer which is a basic disk using space from another partiton which is a dynamic disk. Partiton commander 8.0 wouldn't do it. Didn't have enough free space on the disk and it didn't like the dynamic disk.

I'll add, disk management software/drive overlay software probably is the biggest culprit to your problem. That and NTFS. DOS disk utilities won't work on NTFS as you know. If you get rid of the disk management software thats loaded you might be able to recover with a repair install of Windows, or use partition commander to repartition the disk and move what you want to save to another partition and do a new install. If you think you will ever need to resize disks and want to use something like partition commander, don't convert to dynamic disks. leave em as basic disks.

I had the same stop error when my harddrive failed. I tried everything, including contact the tech support, and had to replace it. I was able to recover all of the data. I simply setup the OS on a new HD, then installed the failed HD as the slave, and transfered the data from the slave to the new master. This worked for me and I was able to recover everything.

I FOUND MY PROBLEM WITH ERROR 91 DISK MGR HAS BEEN DETECTED.... ON ANY POWERQUEST RESCUE DISKS SUCH AS DRIVE IMAGE 2002, BOOTMAGIC, PARTITION MAGIC 7 AND 8..."RESCUE DISKS". SOURCE OF PROBLEM..MAXTORS DISK FORMATING FOR PREPARING HARD DISKS. IF ANY ONE DISK HAS BEEN FORMATED WITH MAXTOR DISK PREPARER, THE PRIMARY MASTER, THE PRIMARY SLAVE, OR EVEN AN EXTERER ONE TOUCH EXTERNAL 2.0 USB DRIVE, ATTACHED TO A SYSTEM, THE RESCUE DISKS WILL COME UP WITH THE ERRROR 91. I USED MAXTOR'S UTILITY TO QUICK FORMAT WITH WRITING ZEROS TO THE INFECTED DRIVE, BOOTED UP WITH PARTITION MAGIC FLOPPIES, PARTITIONED DRIVE AND ALL WAS FINE. I AM CONTACTING MAXTOR ABOUT THIS TO SEE IF THEY ARE AWARE OF THIS PROBLEM AND IF THERE ARE ANYOTHER SOLUTIONS. THERE IS NOT AN ACTIVE OVERLAY, BUT SOMETHING IS EMBEDDED IN A "MAXTOR PREPARED DRIVE" THAT THE POWERQUEST RESCUE DISKS SPOT AND THEN WILL NOT BOOT IN PROPERLY. WESTERN DIGITAL MIGHT DO THE SAME, I DON'T KNOW. HOPE THIS HELPS SOME OF YOU.
