Mirroring Hard Disk with XP

by amacfarl / June 3, 2004 7:59 AM PDT

I have the following setup:

Hard Disk A : Windows XP and Programs
Hard Disk B : All Data

Now, I would like to have a backup of both Hard Disks incase of any issues. With regards to the data, this is no issue. However I have questions regarding Hard Disk A.

If I make a direct copy of Hard Disk A onto another Hard Disk (i.e. no backup program). Would it be possible to boot from this hard disk? Therefore if anything did go wrong with Hard Disk A, I could make a direct swap and boot from the backup Hard Disk????

Thanks in advance

Only XP Pro may have mirroring, but frankly, I've never found mirroring to save me since once the delete key was pressed, all the files on the mirror were gone too.

Maybe a simple copy using Symantec's Ghost will do?

Of course, even that won't be a proper backup.

Re:Mirroring Hard Disk with XP = Good way to lose it all.

Read and take note that there is no exit off the highway.

"WARNING: After you convert a basic disk to a dynamic disk, local access to the dynamic disk is limited to Windows 2000 and Windows XP Professional. Additionally, after you convert a basic disk to a dynamic disk, the dynamic volumes cannot be changed back to partitions. You must first delete all dynamic volumes on the disk and then convert the dynamic disk back to a basic disk. If you want to keep your data, you must first back up the data or move it to another volume."

Converting from Dynamic back to Basic
by wyonson / September 29, 2009 10:37 PM PDT

I have seen a lot of traffic regarding the Dynamic to Basic disk converting. I just recovered from this situation. Here is what you can do and not loose any data. Using Windows XP Pro's disk manager delete the partition, if it will let you, and convert from Dynamic to Basic. Ignore all the warnings, sounds severe and scary :-|. Once the process is done your disk will show as a blank disk, no partitions, no data, just a basic and blank. Now use a partition recovery utility, I used Acronis Disk Director Suite v 10, select the drive/partition and select Wizards/Recover partitions. It can take a while but it did work. In fact the disk would not boot before the conversion and after the conversion back to basic all was well. In case it matters the disk used was a Maxtor 200 with 40 GB of data and the end result was one 40 GB system partition, one 40 GB data partition and 100 GB of un-used space.

So you had no backup plan?

I read it twice and it appears there was some aerial acrobatics and no net. While many times it works, what is the plan if it didn't?

There is always a backup plan

I had previously created an image of the entire drive as part of my conversion process so had the restore not worked there was no danger of data loss. When I converted to Dynamic my disk became unusable so my choice was recover, convert back to basic and recover the deleted partitions, or restore from image. Even with out the image to rely on I was still confident of data recovery. There is always the danger of loosing data and it would be nice to know that if some one made the fatal mistake of converting a disk before backing up that all is not lost...yet.
