I recently bought a new Caviar Green 1.5TB HDD, model # WD15EARS. It was working great for about a month until yesterday. Bios detects the hard drive and isn’t reporting any issues. I connected another hard drive with a fresh copy of Windows 7 so I could access and backup files from the 1.5TB hard drive. Problem is when I have the 1.5TB connected, it makes my other hard drive unstable. It becomes so slow and sometimes it just freezes. I try to access the 1.5TB from Windows’ My Computer, but it doesn’t let me. It shows the drive is there, but it won’t let me access anything. I disconnect the 1.5TB and everything goes back to normal.
This is a fairly new hard drive. I doubt it’s defective or dead since I never received any SMART warnings. I have no problems at boot up. My PC just freezes at the Windows 7 loading screen.
I hope my hard drive isn’t dead. I just backed up everything from my previous dying hard drive onto this one!
Here are couple of photos I took with my camera when doing the diagnostic tests. Sorry for the poor quality. I couldn’t take a screenshot.
Edit # 2:
I was successfully able to transfer files to my backup hard drive using Active@ Boot Disk. I used the GUI features because the DOS prompt couldn’t find the User’s folder in the Windows 7 root directory. Anyway, it seems that transferring files from my 1.5 TB to my spare HDD was pretty quick. Only problem was the Active GUI took forever to load! I don’t think the drive is dead, mechanically. Probably some of the electronics on the drive are malfunctioning? It seems the 1.5 TB is hindering the performance of the CPU and/or RAM. This would explain why the other operating systems on my other drives were performing very slow.
