Dynamic Disk Invalid

For Dynamic Disk Invalid, typecally your operating system may not support

for dynamic disk. such as WinXP Home Edition, Win7 Home Edition will show a

dynamic invalid disk in disk management. A called Dynamic Disk Converter 3.0

(http://www.dynamic-disk.com/) can revert an dynamic unreadable disk and invalid

dynamic disk back to basic disk without lost data. I tested the program

on VMware, work fine.

Vista Ultimate, Invalid Disk Pack

18-Dec-09

Hi!

A weird problem. I used to have 3 USB disks (dynamic GPT) running fine under

Vista Ultimate. Then I made a fresh Windows 7 Home Premium install. Noticing

that it did not recognise my disks (and other problems as well), I decided to

go back to Vista Ultimate (using Windows.old).

But now the original Vista Ultimate installation did not recognise them

either! They have status Invalid in Disk Management Console. DISKPART sees

the disks, and also the partitions, but it does not appear to find any

volumes. Any command I try to do returns the error message that it is not

allowed on invalid disk packs.

Please, dear Internet God, find me a solution. I do not want to lose almost

4TB of data gathered over years.

Hi!

Thanks for the link, but unfortunately I could not find anything useful in

there. None of the lists of status messages in it, or in any of the links it

provided, even listed the "Invalid" status that I have.

So, please, if anyone has any other helpful suggestions it would be much

appreciated. I do not want to format the disks unless absolutely necessary. (I

can recreate the data on them, but it would take weeks of work)

I read somewhere that the Home versions do not support dynamic disks. I feel

totally misled there, because it said nothing about that when I bought

Windows 7 Home Premium, nor did the Upgrade Advisor say anything about it. I

have complained to the store, but of course they remain silent. Interesting

thing is, when I tested the Ultimate RC, I had the same problem. But that

time when I switched back to Vista, the disks did not disappear there as

well, that only happened with the RTM. And besides it does not make sense to

not support dynamic for home users. I am sure lots of Media Center users need

to have large volumes with their media files. Yet are not interested in all

the business functionality.

Philo, if you have a better option than dynamic disks for creating volumes

covering several disks I would love to hear it. My folder containing my DVD's

cannot fit on one disk alone.

anyway, if you get it sorted out

using a hardware RAID method is a better option than any type of

software RAID or dynamic disk

but I advise against disk spanning of any type

since in the event of a problem , data recovery is difficult at best

Hi!

Importing it as a foreign disk was my first thought. But unfortunately it

does not see it as a foreign disk, so that option is greyed out. If I could

find a way of fooling it into thinking it was a foreign disk, that could

help. Is it a registry setting?

I do not have a second computer I can test it on. But I do suspect that if I

could only import it, it would be alright.

I did consider RAID when I made this setup, but I read lots of people who

had problems, and got lost with all the types of RAID. And it was more

expensive.

but unless you get specific advice from someone who really knows what

they are doing...I would not fool with anything at this point.

Hopefully you will get it sorted out

and I really advise you to not use either RAID or Dynamic disk

Hi!

I have managed to solve it now. The free software TestDisk,

http://www.cgsecurity.org/wiki/TestDisk_Download, rebuilds the partition

tables from scratch. It only took a few seconds, and all the data is there,

intact.

Apparently the Windows 7 installation corrupted the partition tables for

some reason.
