problem shifting hard drive

[cheetahdriver]

I picked up a second 2623-DDU T60 when I started having problems with my "A" machine, thinking I could just pull the HD and swap...WRONG.

There is some sort of issue between the machines, I get a 0x0000007b error when I try booting the new machine with the other HD. Looking this error up would seem to indicate that there is some sort of hardware difference between the two units, despite the fact they are the same model. The second unit is labeled as a "Lenovo" whereas my "A" unit only has "T60" below the screen.

Any ideas where the difference may be?

I can take the HD from my 2323-D9U and put it in my 2623-DAU and boot up normally.

Go into BIOS Setup and set the SECURITY setting for the Pre-Desktop-Area to DISABLED and see if that helps.

I have swapped drives between two 2623-DDU's before without any problem. The "B" machine booted just fine with the "A" machine's drive. The "A" drive didn't seem to notice any difference. There was almost a year's difference in the manufacturing date. The only thing I can imagine creating a problem would be if you swapped the drives then immediately tried to boot up the "B" machine attached to a mini-dock with some different peripherals plugged in.

Assuming you made your Recovery disks, you could try just installing the drive and doing a factory restore. Even if you didn't, perhaps you could go back and reinstall the drive in its original bay, boot that computer and create your R&R disks, then swap and restore. Let us know how it turns out.

The security setting didn't make any difference, still getting the 0x0000007b error. I will try the R&R next week, have to get everything ready for a plant down call. I suspect that it has something to do with a chip change or something between motherboards.

Its somewhat disappointing, I had hoped to be able just to swap and go. It's never that easy though....

try reading up on this site if its XP:

They suggest that the mass storage controller might be slightly different between the models and the drive does not have the drivers and registry entries to handle it.

trying this again, i got out my XP disk to try a repair. interestingly enough, booting off of the cd, i could not get XP to admit that it had a hard drive attached at all. it will run fine with a seagate 100gig ST910021A8 (lenovo 39T2783). however, with a Hitachi HTS721010G9SA00 (lenovo 39T2614) it will not see the drive at all.

the system BIOS sees the drive fine.

edit

ok, got it. the drive SATA was set AHCI(?), when i set that to "compatability" it all started took off fine.

Check both BIOS's, is compatibility mode or AHCI set for the hard drives in both? They need to be the same.
