[QUOTE="oxnard, post: 1187811, member: 192660"] While installing my drives into my new NewerTech Guardian MAXimus RAID-1 enclosure I managed to somehow mess up my 2TB Hard drive (they neglect to mention when you put your drive into the enclosure and turn it on it will erase the existing partition on them). I believe its just the partition table, however I am not 100% sure. So far I've tried a few utilities to recover the data: I let DiskDrill run for 3 days and it was only able to recover only some files and with no filename or folder structure at all, I could recover some of the music, but most of my data is completely useless in this format. I tried a second utility called TestDisk, this seemed to find the deleted partition and have the ability to write the partition back to the drive, but when I tried to write it back I got the error: [CODE]Function write_part_mac not implemented Use pdisk (Mac) or parted (Linux) to recreate the missing partition using values displayed by TestDisk[/CODE] Now, this would be fine to use pdisk, except I'm using an Intel Mac and according to TestDisk's wiki: As far as I know I should be able to do it with hdiutil, but not sure how. I tried: [CODE]hdiutil pmap /dev/disk2[/CODE] I don't know what I'm doing wrong...:\ Machine Specs: MacPro3,1 (Intel) Mac OS X 10.6.6 SL Drive Specs: [B]Disk Description:[/B] Hitachi HDS722020ALA330 Media [B]Total Capacity:[/B] 2 TB (2,000,398,934,016 Bytes) [B]Connection Bus:[/B] SATA [B]Write Status:[/B] Read/Write [B]Connection Type:[/B] Internal [B]S.M.A.R.T.
