I have been running ArcGIS with HAZUS-MH software (natural hazard analysis software, besides the point) and needed to get back the additional 21.06 GB on my 160GB HD. I ran PartitionMagic and merged the two drives together and after the merge process, I got the "Disk Read Error has Occurred" C+A+D.
I have XP, one HD, and plenty of data that I cannot loose (senior thesis deadline coming up soon). I read in the other post that emsaddict was able to browse the 160GB HD from an additional drive. Should I go and buy an additional HD to avoid too much trouble?
