They can be seen in Explorer and Disk Management, but not the full 3 TB. One partition shows as unformatted, the other as unallocated.
OS is Win XP and motherboard is Gigabyte GA-M56S-S3. It can't read all of a 3TB drive by default and I'm pretty sure I had to use Western Digital Disk Wizard (Acronis True Image) to enable all 3 TB to be available.
If I run Disk Wizard again now it offers to allocate the unused space.
Logic (or wishful thinking) tells me I must do this before the two partitions can be seen and hopefully everything restored. but I'm too scared to try in case I lose the data. There's a lot of it!
Anyone else been in this position, and what did you do ?
