Odd hang on XP reboot
 

Running under XP-SP2, one day we got a hang on a reboot. Just after the normal display of the XP logo with a black background, the system froze.

We got exactly the same situation after the following operations:

- Restore of a previous XP onto the same spot
- Installation of an XP-SP2 from scratch: hang on the first reboot from the xp installer after it’s finished with the copying of files
- Replacement of the disk by another disk and Installation of an XP-SP2 from scratch: same hang as above

Oddly enough, the installation of XP-SP1 was successful and things appeared to work properly. When we successfully installed the MS upgrade patch to SP2, we ran into the same hang at startup.

Another symptom : disk copies using Acronis Disk Director Suite are unusually slow: the copy of a 4.5GB partition from one disk to another required 1 hour and a half!

Sounds like a hardware problem - try running some diagnostics...

It turned out to be a defective disk cable.

thanks for posting back with your solution!
