I have an iSCSI Target drive that was working fine after creation for a few days. After i copied about 40GB of data to it i lost access to the drive. the file system had changed to RAW and windows wanted me to format. I did not format but was able to convert it back to NTFS and run CHKDSK which restored all my files.
Google search tells me how to fix it but i'm very concerned about what caused this problem. I have not been able to find any explanation of what could have caused it. Does anyone have any ideas ? Before moving my 150 TB of production data i really want to know.
Thanks
