I had a problem on my HP Imelda 1437, so I used system recovery to bring the computer back to factory settings.
As I had a second drive, which did not want touched , I unplugged it.
Run the recovey system,plugged in my second 'data' drive, and the system now tells me that the drive is 'Raw Data' and Unformatted.
I assume that the BIOS has been changed, as the system was originally a One hard drive system, is there any easy way to restore the bios, without undoing the covers, removing the battery and /or flipping the Bios clear switch./ Thanks Terry
If the two drives are both the same, IDE or SATA, then open the external drive case and swop the "invisible" drive into the external's case.
If your computer can read it then at least the invisible drive is OK. The problem must lie with either connector problems to the motherboard or (less likely) software configuration.
Have you really checked the cables to the internal HD? If IDE, and there is a spare power connection try that. and also be sure the data cable is mounted correctly. (Some few older computers can allow the data cable to be the wrong way round)!
Both drives are IDE and both internal, I am Using XP PRO, The system will see the second drive, but see's it as Raw data, however if I go into disk management, it shows that there is data on the drive, but I cannot access it.
I have tried changing the Data Cable and the Power cable, put the drive into another machine with the same result.
I tried Erasus recovery and it found some files, but after about 3 hours it crashed out.
This has created a new problem in that my C: drive is now listed as D:, and boots from there (No D: is not a boot drive, just data storage), and C: drive has dissapeared.
I have a back up of most of my work, however, the backup program will not see D:, where the backup was stored. Terry
