Very strange thing. Had 3 computers come in the shop within the last 4 days, all with the exact same problem. All different makes of computers, all different HD's and some SATA and some IDE. All of the computers do not post "verifying dmi pool data" or where that would actually come up after the normal post screens. Can boot from CD fine. Tried WINXP PRO repair option from install disc. After repair 1st stage completes, then on reboot back to same stop issue, before verifying dmi pool data can even appear.Tried chkdsk /r from Recovery Console from Install Disc. Tried bootcfg /rebuild. Tried fixboot. Nothing has worked. All 3 HD's can be seen in another computer as slave and files accessed easily. This seems to be more than coincidental for type of issue I have never seen before, especially in short time window. Been in the game for 20yrs.
