My disk physically died (IC25N040 in a IBM T40 laptop). It never spinned up after a huge click. Of course our tools work perfectly for software recovery (it took 6 minutes in my case) but because I didn't have anything on NTFS I had the NTFS image on disk thinking that if the disk crashed I could recover Windows quickly using IBM's XP Recovery CD set. I was wrong. It took almost two months. IBM support is superior but whatever helpful they were, the technology they provided didn't work. I don't detail why, only mention when I managed to recover it in the end. The 4 recovery CD's are apparently an IBM branded Disk Image from PowerQuest (now Symantec). It uses Windows 98. The whole recovery process took 1.5 hour attended. I had to sit next to the computer, replacing CD's, hitting keys, reconfiguring BIOS, etc. I tried the same with open source tools, ntfsprogs from a DVD (basically ntfsclone the minimal image then ntfsresize to adjust to the underlaying partition size). The recovery took 23 minutes unattended. Just put the DVD in then start the recovery process and do whatever you want until it's ready. I guess the open source way could be still improved if the image is compressed. I'm able to compress the XP image to about 50% so since the bottleneck of the recovery process is the bandwidth of the DVD device thus the recovery time could be reduced maybe to 12-15 minutes. Proprietary recovery: 1.5 hour attended Open Source recovery: 15 minutes unattended IMHO there is a slight difference between speed, price and convenience ;) Szaka |
