This is driving me nuts, if anyone can help. And yes I've tried most everything, so here goes... Rig: Paragon Hard Disk Manager 11 Pro, Windows XP Pro SP3 32 bit I have a hard disk that has a few known bad blocks. Have run CHKDSK /F over the partition. Windows know about the bad blocks. However if I try to run a Paragon backup of that partition, Paragon locks up around where the bad blocks are - and have to kill it in Task Manager. The manual says Surface Test enables to test surface of existing partitions and blocks of free space for bad or unstable sectors. If found any it automatically marks them unusable in the file system metadata, thus minimizing the risk of data loss. Well this doesn't happen. When I run Surface Test, it aborts around where the bad blocks are (already sorted out with CHKDSK /F) with an error "operation interrupted by user". The log file says Result: Aborted by user So either i have missed something or Paragon cannot handle bad blocks. So cannot image backup/restore partition was the primary reason for getting Paragon. Heellllppp!!! Please.
