I don't know if you've already replaced the disk at this point, but if you didn't, stop using it and don't run scandisks on it; this stresses the disk unneccesarily and may cause more sectors to fail or worse, cause the drive to fail completely. Your priority is getting the data off the disk - I think Jmone's suggestion is a good one.
I wouldn't clone the drive with cloning utilities unless there is no other way. The sync utility suggested works from Windows, your data is static (DVD rips only?) and you can monitor the drives health and temperature from Windows. Rebooting to some recovery mode doesn't allow for that.
Thanks, I have stopped CHKDSK and am now using FreeFileSync to copy the files over.
I feel you pain.... I bit the bullet and built two 30TB pools (on mostly 4TB Hitachi) but it cost $$$$. Those EARS are absolute crap. The good news was some of mine were in WTY so when I RMA'ed them I got EARX models back and so far no issue with them (using them in my WHS as the OS and an OS backup drive just fine).
I think they had a three year warranty when I purchased them (all HDD manufacturers seem to be scaling back their warranties now) so I should be covered. It seems unlikely that I'll get another WD20EARS back.
Also - 4TB HDD conserve Sata Ports and Bays in you HW setup and are now under $200 a pop.
I wish they were that cheap here. I have seen a deal on a pair of 4TB Seagates that works out about that price though, but to be honest I've not had great luck with Seagate drives in the past and am hesitant to buy them.
I agree with you about always buying the highest capacity drive making the most sense, even though 3TB is where the best value is at right now.
I wish they would get around to increasing capacities again. It seems like we've been stuck at 4TB for a while now, and current efforts are on producing 4TB drives with one less platter, than increasing the upper limits.
Right now I have:
120GB Patriot Wildfire SSD
1.5TB WD15EADS
1.5TB Samsung
2.0TB WD20EARS
2.0TB WD20EARS
4.0TB Hitachi Deskstar
The two 1.5TB drives are 3-4 years old at this point, and should probably be replaced before they fail.
It seems like I am taking a risk if I stick with the WD20EARS, so even if I get a WD20EARX back, I should still be replacing the other one.
The thing is that I just don't like getting rid of old drives that are still functional. I still have a working 500GB drive kicking around here somewhere. Perhaps I should be re-purposing them as archived backups now.
I bought one of those SATA>USB3 docks (StarTech) but had limited success with it. Whenever I tried testing the disk with HDsentinel it was throwing up errors that basically indicated that the connection was unreliable, even if the drive wasn't completely disappearing from the system. It was a dual drive dock though, so perhaps I should try a single drive dock, or an eSATA one instead.
I like the Hitachi 4TB Deskstars. They are big, fast and rated for 24x7 use. That said the oldest I have is just shy of 400days of Power On Time and I've not had an issue (see pic)....time will tell.
I have one of those drives and it seems fine overall, but it is quite noisy, and one of the hotter running drives in my system. It's consistently 4-6℃ hotter than the WD drives. But I don't know if that's just an issue with how it's being reported. The 1.5TB Samsung I have reports its temperature as being 10℃ lower than every other disk in the system. I haven't measured it, but that seems highly unlikely.
I didn't realize the Hitachi was rated for 24/7 use, but I was somewhat concerned by the 1 year warranty when I bought it. At the time, I needed 4TB and couldn't afford anything else with a better warranty though. (3 year WD Red, or 5 years on an enterprise drive I think?)
I believe up to 45C operating temperature is perfectly fine. I don't even worry hitting 50C on a large copy/sync job, as long as it drops afterwards
Yeah, it's not usually a concern, but that seems the most likely culprit considering that temperatures have been about 10-15℃ warmer than usual this last week.
I really do need to sort out a proper storage system, but every time I look into it I get 20 different recommendations, which either cost a fortune or compromise in some way that I just decide it's easier to stick with what I have and add another disk somehow.
Part of the problem is that where the HTPC is located it's visible (so aesthetics matter) and only a tower will suffice - a rack style case like the Norcos will not fit.
Cables for it are run through the walls (which have their own issues, like USB expansion) so that there's minimal noise inside the HT room, but due to its location, noise is still a concern.
I do have ethernet wired through the walls, but I don't know if the installer either skimped on the cable costs (I specified Cat 6) or if there's something else causing this, but I only seem to be getting 100mb rather than gigabit speeds through it. This has not been a major issue so far, as it's only used to share a DSL connection, but it would be a problem if I was moving to networked storage. Even gigabit isn't really fast enough for that now.
If you're ever moving into a place and getting work like this done, make sure you get a lot of references for the installers and oversee the job yourself. I went with a recommendation, and let a (non-technical) family member oversee this instead, and there have been all sorts of issues with the cabling - and due to how it has been installed it's a huge job to try and replace anything or run a new cable.
