I have a Sata II 80gb HDD that is formatted as "Dynamic" and I WANT to get it back to "Partition - Basic". Is it possible? How would I do it?

Thanks

GerryNot if it's your boot DISK.

WARNING: After you convert a basic disk to a dynamic disk, local access to the dynamic disk is limited to Windows 2000 and Windows XP Professional. Additionally, after you convert a basic disk to a dynamic disk, the dynamic volumes cannot be changed back to partitions. You must first delete all dynamic volumes on the disk and then convert the dynamic disk back to a basic disk. If you want to keep your data, you must first back up the data or move it to another volume. My boot disk is an 80 gb IDE drive and has XP on it. Data storage is on a 1 terrabyte drive (SATA II)

The drive I want to convert back is a 80gb SATA II drive - I have deleted the volumes but cannot find a way to format as "Partition - Basic" just going round in circles. When I get it back I will disconnect the IDE drive and set the 80gb Sata as the boot *censored* with Windows 7.

I would be grateful for any help.

Gerry  You have 3 drives:
80GB IDE -  WinXP Boot Drive
1TB - Storage
80GB SATA - Future Win7 Boot Drive

I haven't done this, but I suspect you Delete Volume and then Create Partition, then Format.  If Windows won't do it, try PARTED Magic.

You can ALSO download the HDD manufacturer's tools for partitioning and formatting.  Some versions are for Windows, others create bootable CD's.
