Drive letter missing

By balak46 ·
I have two problems, they could be related.

Very strange things happened:

I cloned a 40G to 160G; Took out the old and installed another 40G I have been using as a data disk.
The drive letter has been missing when I reboot with the cloned drive. I do not want to remove partition on \ until I know what to do. My data is there..?
1. What causes the drive letter change? How will I restore it to its original letter?, i.e., \

I used Norton Ghost; did havoc. Got rid of it. Actually got rid of all of Norton Sysworks 2006.

Then I used Acronis (a disk cloner). Cloning was smooth but now this drive letter problem. My 160G drive does not boot and I had recloned 3 times using the old C with proper jumperpin change etc..

The XP disk does not bring up the windows configuration (the blue window) if I try to reboot the new 160G. It is so frastrating.

my 2nd Q is: How will I fix the boot in 160G

As the above poster asked is the 160 GIG Drive a SATA? If it is then you'll need to reload from scratch to allow the SATA Drivers to be installed and allow it to boot.

If it isn't that does your M'Board support a 160 GIG Drive from one of the IDE Channels? With every BIOS there is a Upper Size Limit for IDE Drives and if the drive exceeds this limit they will not be recognised by BIOS and will not be able to boot.

But from your description of things it sounds as if you are attempting to boot from a SATA drive when there are no SATA Drivers loaded to allow it to boot. In a case like this with a Clone you can perform an In Place Install of the OS which I'm presuming is XP by following the directions here

If you have any encrypted files you'll first need to save the encryption key by following the directions here

Or you'll end up with unreadable junk as Data.

If you do an Inplace Install you may need the SATA driver Disc that came with the M'Board or system Disc. If you have a HDD that isn't supported by the BIOS you'll need a utility to trick the BIOS into thinking that you have the right sized drive and you will most likely get this from the drive makers web site. Seagate has one but I'm not sure if it works with different make HDD's but a quick Goggle search should uncover something that will work as a generic utility to do the job.

I would hazard a guess that both problems are related to the 160 GIG HDD and until you can get that to boot I wouldn't even consider doing anything else. If you can get into BIOS and look for the 160 GIG drive if it's an IDE Drive and not shown it's too big for your current version of BIOS.

Flashing to the newest version may cure this problem but depending on the M'Board involved it might not have much effect. You need to know if the 160 GIG drive is even seen before you start playing around with it as you still have your original OS & Data intact you don't want to run the risk of loosing anything before you get things working correctly.

Your Data HD should be all right.

As far as why the is missing, my reasoning is as following.
It is probable that the 160GB was assigned as when it was ghosted and therefore was reserved. Mind you that the was originally your 40GB Data HD. When you booted with 160GB HD with the 40GB data HD, it could not assign to the data HD, hence was missing. If you had booted with the 160GB without any other HD, the would have been released.

I recommend the following process.
1. Disconnect the data HD.
2. Boot the computer with the 40GB HD.
3. Shut down Windows.
4. Connect the 160GB HD.
5. Run Acronis.
6. Shut down the computer.
7. Disconnect the 40 GB HD.
8. Boot the computer with the 160GB HD. If the computer does not boot, boot the computer with a Windows 98 Startup disk and run FDISK /MBR and then boot to Windows.
9. Shut down the computer.
10. Connect the 40GB Data HD.
11. Boot to Windows.
