I have a customer who's secondary HDD and external USB HDD connected to an XP machine both suddenly became unable to be accessed eg did not show up in 'my computer'
The drives still appeared in Disk Manager, but were marked as dynamic rather than basic disk initialization, hence the inability to access
The external usb drive did not contain essential data , so i converted it to basic, and assigned a drive letter after which it became accessible
the secondary HDD contains data that needs to be kept so my question is:
1. How can i convert HDD to basic / be able to access drive without losing data?
2. What might have caused this to happen in the first place?
