So I had Vista installed on a 200gb Maxtor SATA hard drive and about 3 months ago it started making loud noise like beeps at one point it even made a cool melody of beeps. Anyways shortly after it started doing that I got a BSoD while using Vista. I couldn't boot up and the drive wasn't recognized when I booted up my Windows Xp drive. Then I used a disc recovery program to get everything I lost back, but I left the Hard Drive sitting on my counter. Here's where it gets interesting. Last month I picked up the drive to see if there was anything I missed that I could pull off it using the recovery program. However I never needed to use the recovery program. It showed up in My Computer and I just Cut and Pasted everything off. I then formatted and its been in my Case ever since. I even had another Windows Xp OS on it at one point and it booted fine. I used this drive to hold data while messing with partitions on my main 300gb drive, but only for a short time. My question is this. Did my HD actually fail or was it just Vista screwing up. Ever since the first inccident no beep or noises have come out of the drive except during boot when all drives make that one noise. I need a drive to back up some data while using Windows 7 so I would like to know if its safe to use this drive or not? tl:dr; I thought Hard Drive failed but I plugged it back in last month and it worked perfectly and has ever since. Is it safe to use and was the failure actually something else? Thanks for any help.
