I don't remember the last time I had problems with a HD, but I think my drive is on it's way out. A couple of weeks ago, during a backup I noticed it was taking longer than usual. Then the system froze and I knew it was a HD issue. At first I thought it was with my eSATA dock, this has happened a few times in the past, but looking at the system log it was reporting an error on my main HD not the external drive.
I ran a chkdsk to scan for bad sectors over night since it takes about 4 hours on this 1.5TB drive. It found and marked 3 sectors bad. The files on the bad sectors were in a Steam game, and verifying the files it ended up re-downloading them.
After that I ran the Western Digital diagnostic the next night, it found and corrected errors. I then alternated between chckdsk /b and Western Digital diagnostics until it was no longer reporting errors.
The past few days though I've been getting errors in the event viewer saying the device has a bad block, so I ran chkdsk again last night and it showed no errors.
Just now while Steam was updating a game, Steam reported a write error, and once again the event viewer shows a disk error at the same time Steam had the write error. I restarted the update and it finished, but verifying the files on that game after it was done caused it to re-download 1.4GB, nearly the entire game.
I was already picking parts for a new system, and this is accelerating that process. I wasn't planning to buy a new drive because I have enough space on this drive. I was going to buy a larger SSD to go with this drive, but now I have to pick a new drive for my new system too. I just hope the disk holds up until then.
Wasn't there an article linked here a few weeks or months ago evaluating which consumer drives were most reliable? I think I remember it ranking HGST and WD at the top, but while browsing drives the other day, reviews for every manufacturer seem mixed. Since I'm doing fine with 1.5TB, I was looking at a 2TB replacement, but it looks like 3TB is better in price per TB. I also think I remember the article I was referring to earlier (or it might have been another) that showed reliability dropped in drives over 2TB. So any recommendations?
