I purchased a new Hitachi Travelstar 200GB SCSI disk for my laptop. I used Acronis True Image Workstation to backup my C (OS Partition) and D (Data Partition). Both Disk Director and Windows report that my hard drive is only 110.4GB in size. I ran Recovery Expert and it says there is no unallocated space (as does Disk Director). I used Disk Directory version 10.0 (build*2,160) to create 2 new partitions. I created a C partion of about 35Gb and allocated the rest to D. It was about 155-160GB. I rememember that. I then restored my C and D Drive using TIW. I did not pay attention to disk space at this time. I just made sure my comptuer booted and behaved OK. After restoring my C and D drives using Acronis True Image workstation I created a 3rd partion. During analysis I got an error about unable to read a sector. I ignored it and the new partition was created. I immediately did chkdsk /f /r on C and D. It took a very long time. Once completed Disk Director and Windows say my total hard drive space is 110.4GB. Where did the rest of the space go?? Disk Director recognizes the hard drive model and manufacturer. I verified this is a 200GB hard drive and the D partition was about 155GB-160GB when I did my last Disk Director commit. The size changed during the D drive restore of as a result of the chkdsk. I have no idea what happened. Where is my disk space and how do I get it back? Also Disk Director reports all disk space is allocated. Currently Disk Director reports my C drive is 35GB, my D drive is 71.2 GB and my E Drive is 4GB. What happened and what can I do to get back my missing disk space?
