A coworker has a Dell 1545 that they said took a small drop off a couch (though no obvious damage), and the laptop stopped functioning ever since. I took it... never got past Windows logo, safe mode didn't work either. I was finally able to get the files copied off using Safe Mode with command prompt.
I ran hard drive diagnostics (SeaTools), and it said the drive (250GB Seagate drive, 2.5" SATA) was bad. So, I replaced it with an old WD 250GB drive I had on hand, just to see if I could get Windows to load, and see if there were other problems. Well, I was able to get Windows to load, all seemed OK, but soon after Vista started warning me that the drive was about to die. I booted an Ultimate Boot CD on a thumbdrive and ran Data Lifeguard... it found numerous errors on that drive... which is entirely possible, as I said it was an old drive and I was just seeing what would happen. But, the laptop is fully functional with this bad drive (other than failure apparently being imminent)
So I ordered a new WD 500GB drive. ran UBCD WD Data Lifeguard, drive is not recognized. Go to BIOS, drive is not recognized. Put the 250GB drive back in, works fine. Sent 500GB drive back, got another 500GB drive... same issue, not recognized. Put 250GB drive back in again, and AGAIN it's fine.
Any opinions on what would cause that behavior, what I should try next?
