My system is Windows 2000 Pro., SP4. I have 1024MB memory and my processor is an AMD 64 Athlon 3700+. I am running ATI 9.0 build 3567. I have 4 fixed hard drives. Two are 120 GB each, one is 160 GB and the last is a 250 GB. The following is the drive layout shown by Windows Drive Manager. WDC WD1200JB-00DUA3 [Hard drive] (120.03 GB) -- drive 0 (SATA) c: (NTFS on drive 0) 34.52 GB 23.22 GB free f: (NTFS on drive 0) 26.16 GB 19.93 GB free g: (NTFS on drive 0) 1.41 GB 1.38 GB free h: (NTFS on drive 0) 26.48 GB 25.76 GB free i: (NTFS on drive 0) 31.46 GB 31.37 GB free WDC WD1600JB-00GVA0 [Hard drive] (160.04 GB) -- drive 1 (IDE) d: (NTFS on drive 1) 52.84 GB 46.02 GB free j: (NTFS on drive 1) 53.39 GB 53.31 GB free l: (NTFS on drive 1) 53.81 GB 53.33 GB free WDC WD2500KS-00MJB0 [Hard drive] (250.06 GB) -- drive 2 (SATA) q: (NTFS on drive 2) 250.06 GB 249.13 GB free WDC WD1200JD-00GBB0 [Hard drive] (120.03 GB) -- drive 3 (IDE) n: (NTFS on drive 3) 35.02 GB 33.16 GB free o: (NTFS on drive 3) 45.01 GB 44.38 GB free p: (NTFS on drive 3) 40.00 GB 37.58 GB free When I run Acronis True Image and try to backup the drives, the 250 GB SATA drive (drive 2) is not seen by Acronis either inside Windows or in a boot CD start of the machine. When run in Windows, the Acronis backup wizard shows disk 0 as disk 1 (partitions c:, f:, g:, h:,and I. Disk 1 is shown as disk 2 (partitions d:, j:, and L. Disk 3 is shown as disk 4 (partitions N:, o:, and P. When run from the boot CD, Acronis backup wizard shows disk 0 (partitions c:, f:, g:, h:,and I as disk 3 with the correct partition numbers. Disk 1 (partitions d:, j:, and L is shown as disk 4 with (partitions D:, J, K. Disk 3 (partitions N:, o:, and P is shown as disk 2 with ( partitions E:, L:, M. Even though the Q: drive doesn't show up as a drive to back up it does appear in Acronis' explorer view when I am prompted to choose a destination location for the backup. Can anyone offer a suggestion as to why the program doesn't see the drive as an imageable partition? TIA, Cecil B.
