Would you trust this HD?

Greetings all!

I have this 3 TB WD Caviar Green that I use to back up videos and photos. It's not the only backup copy, of course, being an internal, always connected drive and all.

I'm using Win 8 now and the drive was originally quick formatted under Win 7. There was some system or temp folders left on the drive from Win 7 I could not delete no matter what and it started behaving a little strange in other ways too. When l was trying to update my external backup HD by copying from that HD, I got an error on some files saying something like cannot read from source file or disk. Those files couldn't be copied off the disk even though I could open them and they seemed ok. However I guess media files are error tolerant and can take some corruption before becoming unopenable.

I then slow formatted the entire disk and did thorough chkdsk on it with /r parameter and nothing was found to be wrong, no bad sectors or anything (all this took a whole day). I also copied 500 gigabytes of files on it and then copied those out to a third drive without any issues so now it seems to work.

Would you say this drive is working really? What could cause such issues?

Sounds like you had a corrupted image before as you should end up with zero files or folders after a quick format. But now the format has worked and cleared the drive correctly it should work normally. Your problems were all related to that bad quick format (no idea how that failed but it clearly did).

Actually it was empty after the quick format in Win 7 but those few folders left on it couldn't be removed in Win 8.

I have no idea what application created them in the first place as on that drive I had nothing but backups. I tried Google to find out what they could be but their names were quite cryptic and random looking too so I came up with nothing.
