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!

From this article it looks like the data is gone:  https://technet.microsoft.com/en-us/library/cc731274(v=ws.11).aspx

You may be able to get a professional data recovery firm to attempt recovery - but that'll be very expensive AFAIK

Try http://www.runtime.org for starters.

Good luck!
