How to solve this irritating problem!
I recently upgraded to Windows Vista Home Premium. “Why?!” I hear you all cry. Well, it was simply to take advantage of being able to use more then ~3GB of ram. Which I am now doing, having wacked in 8GB of some rather shiny OCZ pc8500 memory.
A few issues abounded once I’d installed, one rather annoying one being that my 500GB second hard drive (I run a 74GB Raptor as my main disk) had been marked as ‘Invalid’ in disk management. Not being willing to switch the disk to another machine, copy the data, format, copy the data back and then reinstall the disk in my windows computer, I needed another solution.
Which was found in the rather excellent disk utility TestDisk.
After extracting the TestDisk archive to a folder, run the program, select the relevant disk, analyse it, set it as a primary partition and then reboot.
Thats it.
For Dynamic Disk Invalid, typecally your operating system can’t support for dynamic disk. such as WinXP Home Edition, Win7 Home Edition will show a dynamic invalid disk in disk management. It seems that upgraded Dynamic Disk Converter 3.0 (http://www.dynamic-disk.com/) can revert an dynamic unreadable disk and invalid dynamic disk back to basic disk.
I’ve only recently started using Win7, so a useful tip. Thanks!
