This is where you can make the dynamic to basic drive conversion happen. Select Write, then press Y to confirm that you want to write the new partition structure to disk.Quit the program, reboot the drive you just modified and enjoy your new basic drive.
I got the same problem.accidentally i converted my 80 gb hdd to dynamic and deleted a partition while trying to recover back to hdd.I tried almost all the softwares(near about 25) available on net.I tried this article too but test disk gave me wrong information that on my dynamic disk have 5 partitions although i have 7 on basic disk that were converted into dynamic disk.I found only 3 softwares identifying correct partition 1st power data recovery ( ) and Paragon Hard Disk Manager, version 8.5.(Even paragon says that its able to convert dynamic to basic but in my case it was not able but it shown all files and folders in each partition through volume explorer option and i recovered files safely by both softwares).3rd software was r studio.some other best links i found were -Dynamic-Disks-Back-to-Basic-Disks.aspx =102958&highlight=dynamic+diskacronis also claims but it dint recognized my dynamic partitions.Only one software left to which i will try in night that is Acronis True Image 9.1.I spent whole day for this work so friends save ur time by my hard work.I will say thanks to the writer of this nice article which inspired me to write my experience.if any one has other experience do wrte to help other people as time is damm valuable :-))
I think Microsoft should make clear when you are creating/formatting a new disk the impact of having a drive converted to dynamic. For an end user there is no direct info from the OS, it just ask you to convert it with out any warning or info, im very sure that most end users answer YES without knowing what they are up to.
Good tool, although is it absolutely necessary to backup the contents of the dynamic disk before converting it I thought the idea behind this was to just convert the disk without having to backup or lose data
Note: if you try to revert your dynamic disk to basic, from a working PC with a vista installed, try to use the win version of TestDisk and run it as Administrator so it can detect both your internal and external disks, im have problems using the DOS version.. Thanks..
Thank you very much for the tip. It cured my dynamic disk problem.I saved the files and they ended up on my new drive. It took up most of the rrom on my drive however when I use window explorer I see only about 1/3 of the disk being used. Where are these files stored and under what name How can I look at them
Wow! Fantastic! My xp pro pc crashed and i had to buy a new one and unfortunately there was Vista Home premium installed on it. I wanted to put my harddisk with 500 gb data back in that new pc but then Windows started to complain about dynamic disk. The option i had was to convert it and erase all my data but thanks to Testdisk and your expaining it was just 5 minutes work to have all of my data back!!
My case is similar but of June 2009. I had by mistake converted by 160GB SATA Boot Disk to Dynamic type hoping to mirror it under Vista Ultimate. But then I found that such facility is not available in Vista. I needed to convert the volume back to Basic type as My Acronis Home 12.0 started to say there is no hard-disk to backup! The most elegant solution was to install Paragon Partition Manager 9.0 Professional in Vista. It has built in option to convert the Dynamic Volume to Basic as long as dynamic disk was not expanded to include additional hard-disk(s). The conversion worked flawlessly (though I was quite apprehensive after reading all the comments appearing above!). So people, if your case is similar then do give it a try.
It worked without having to copy files to another HD! Saved me a lot of time moving the HD to another PC or moving files.I changed my MOBO then I had the cant view dynamic disk. KUDOS to TESTDISK and OP!
AMAZING. Works like a charm. Brought my non-bootable (dynamic disk) 2003 DC back up and running in 5 minutes (after 5 days of researching/trying other alternatives). THANK YOU, THANK YOU, THANK YOU!!!
Thanks! You really saved the day. I had one HDD in my laptop(running windows 7 x64) which I converted to a dynamic disk, just to be able to extend one of my three primary partitions. I ended up with a unbootable OS.
The software can only convert dynamic disk with simple volume, in fact, other dynamic volume is more helpful, few people use simple volumes.I found another method that could help you convert all types of dynamic disk volumes to basic without data losing
after 5 days i was spent in trying access my 4 hdd who became dynamic/invalid after new instalation of windows 7,finally i do it in few minutes with test disk and your simply to do list,,,great,thanks,,
I think esues partition manager can safely convert your dynamic disk to basic disk. BTW, when I decide to convert it, I always do error-checking and defragmentation before everything. This would be safer.Also, i found there is a recommendation from Microsoft. That make me easy.
Thanks a lot for a nice note. I had a problem and my primary disk had crashed. I had additional SATA 500G disk which keeps backup. I replaced crashed disk with a new SATA disk and installed a copy of win7. After new install windows refused to show the backup disk with a drive. It kept showing it as dynamic disk . Nothing could be read from this dynamic disk. Converting dynamic to basic was difficult as win7 showed data would be removed. Many software were analyzed but almost every one needed to purchased. TestDisk was as per above suggestion and I got back my backup. I just had to change disk type to P (primary) and reboot. It was 2min task . Thanks a lot to this thread and nice utility
I had just installed a new, faster Windows boot drive in my Windows 7 Pro 64 PC while leaving the old installation intact as a backup, and I accidentally converted the old drive to a dynamic disk while messing with partitions. This utility converted it back to a basic disk for me. I did have to run a Windows repair on the restored drive before it would boot for me again, but now everything seems to be working fine. Thank you!
What a nice surprise. I had mistakenly formatted a 1.0 TB external SATA drive as a dynamic disk under Windows XP. When my XP computer crashed, Win 7 64 bits could not read the disk. I found a couple of possible commercial solutions but possible is the key word because the price to find out if they worked was 30-60 USD. 1e1e36bf2d
