You said that compression is not “on”, which just means the disk itself hasn’t been configured to compress everything. That’s different than having data on the source that is compressed.
I think “compact /s ” will tell you what is compressed (and not), though it will take a while. *From:* [email protected] [mailto: [email protected]] *On Behalf Of *Jake Gardner *Sent:* Tuesday, March 24, 2015 8:39 AM *To:* [email protected] *Subject:* [NTSysADM] RE: Robocopy Question Is the destination compressed? I believe it will uncompress to transfer. What is the amount of uncompressed data? Can you do it in stages? Do 100GB and let the destination have a chance to compress it. See if it matches the source size.

Source drive (dynamic disk) is 500GB with about 150GB free space. Compression is not turned on. Destination drive (basic disk) is 500GB, and its empty Both drives have the same bytes per sector and cluster. Issue is the robocopy fills the destination drive completely and then fails with about maybe 30GB to go. Why does the data take more space on the destination than on the source? Is it because the destination disk is only a ‘basic’ disk? Thanks all and Happy Monday :/ *************************************** *John C.
