    I had an Acomdata external USB IDE HD used as backup storage. The data was password-protected with the software that came with the unit.

    When the USB housing began to fail connecting to Windows, I connected the HD to the motherboard with the use of a SIIG Sata-to-IDE adapter.

    My Windows 7 Pro O/S recognized the drive, but not the data.

    In my frustration, I changed the drive type from 'basic' to 'dynamic.' I didn't format, just changed the drive type. No luck.

    I then purchased an external Sabrent sata/IDE external housing unit... same 'invalid' dynamic error message within Disk Management.

    When I {right-click} on the 'invalid' drive within Disk Management, it gives me these options:
    1) Convert to Basic Disk,
    2) Reactivate Disk, and
    3) Offline.

    Did I lose all my data?
    Is there way to restore access?

    ALL my backup is on this drive. Any suggestions or explanations would be greatly appreciated.

    Thank you!

    PC Info:

    Microsoft Windows 7 Ultimate (SP1) 64-bit
    Intel i5 CPU, 750 @ 2.67 GHz w/16 MB RAM

    If it is in fact a backup of data [and not the only copy] it is simple. Just delete ALL volumes on the drive in question, create one or more partitions and format with ntfs. Copy the data from the original source back to the drive.

    The only way I know of converting a dynamic disk to a basic disk is to do the above.

    If the disk contained your ONLY copy of data, then it is not a backup. If that is the case and you attempted to convert back to a basic disk, you are going to have to either run data recovery software on the drive or send it to a shop that does data recovery.
