Dell desktop - WINXP SP2-two hard drives. On the first, after C and F(DATA), I repartitioned and changed drive letters, and did the same on the second. All looks fine on Disk Director Suite (DDS) (no errors) and also in Windows Disk Management. However, now I can't open DDS without waiting for about a 6 minute "analysis" of each partition after C & F. Acronis True Image (TI) opens slow but won't close for many minutes. Computer Disk Checks are very slow to start. Reboot and Shutdown are VERY slow and Standby is almost impossible. I had to go into Safe mode to run an AVG virus check because it stopped at C\ System Information. Each virus test result is clean except it shows "PARTITION TABLE (MBA) - Changed". I have diskchecked everything and finally used System Restore to go back to before the repartitioning, but it hasn't helped (it did change some drive letters back). I can't use the Recovery Console to rebuild the MBR because the WINXP CD is a DELL OEM and I'm not sure I'm up to doing this in a command window? Might it help to (1) shut off System Restore? (2) Use Disk Management to format all partitions (except C & F) as they are mostly empty? (3) Use Disk Management to DELETE all partitions except C & F and then try again to add partitions with DDS? (4) Totally reformat the second hard drive and then with fingers crossed use my last TI full Disk 1 backup to restore it. Does a TI full disk backup contain the old MBR? Sorry for the length. Any help would be much appreciated.
