They are ex Hitachi drives. I got 3 a little over a week ago. All worked and had decent speeds (30hr preclearing). They run around 3C hotter than the WD green drives I have. The warranty checked out as 23 months on mine.

Actually, to be technical. You don't own this site and your posts and your account can be deleted whenever the owner feels like it. It's amazing how many people feel they have "The Right" to post anything and everything they want on a message board they don't own.....

Parity - same as the data drives unless writing to multiple disks at the same time and then a faster parity doesn't hurt. Cache - whatever you want. You can get more speed on some systems with a fast drive. The ex Hitatchi drives are starting to show up from the new owner Toshiba. Watch for them on sale. If the quality is as good now as back a year or so ago then they would be about the best 3T drive to buy.

Try a check disk (using a Windows PC) on the USB drive.

Last time this came up the cache drive was sick. Try running the reiserfsck checks as called out in the Wiki. Just use the /dev/sdX1 (where X is the letter of the cache drive) and don't forget the 1 on the end.

With the claims on how the drives blow up as soon as power is applied or as soon as the drive is inserted I don't see how you should be concerned after operating for about 8 months with no issues. I've yet to see 100's of different complaints and I'm fairly certain there are a number of people here with NORCO cases loaded with 3T drives not having any issues. I'm not sure what the problem is but I don't believe it's as simple as that web-site makes it out to be.

Remoe all plug-ins and add-ons and confirm the base system is stable. Then, start adding things back on until it breaks again.

If you want to put 6T of storage into the server it requires 2 x 3T drives or 3 x 2T drives. Obviously, the 2T drives requires an extra SATA port and an extra mounting location which also cost money and these combined with drive prices make the 3T drives the best price point.

I have a BE2350 processor and 2 gig of memory. Nothing very powerful at all. The response is not snappy, but it's certainly not slow and it never hangs. Maybe it's your CPU being throttled down much further than some others. http://lime-technology.com/forum/index.php?topic=22633.0 try this command and see what the minimum frequency is sudo cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

I just did 3 x 3T Toshiba aka ex Hitachi drives. The preclear times were 28, 30 and 34hrs. These are 7200rpm drives but still yours should not go that much slower. You've got a problem with your system if your drives are going that slow.

Where did you get a 600A, 120V service and you make money when paying something like $250 per day for hydro?

Ya, I returned a drive not too long ago. It went to Mississauga I believe. I believe the replacement shipped from the US.

If you're in Canada you should be shipping to Toronto and it shouldn't cost $30.

Mine are in 4in3 hotswap bays and they run 2-3 degrees hotter than the WD green drives.

Warranty check on mine was until Sept 2014 so barely even 2 years.... I doubt you'll get 3 years if you purchase them.

The Hitachi drives are running 2 degrees hotter then the WD Green drives surrounding them.

You likely have some bigger issue if that is happening. The drive should not appear unformatted again if you assigned it into the array and it was formatted and appeared as a formatted drive.

At this time, you only get 20 or 22 data drives in an unRAID array. You can either run 2 instances on ESXi or run 2 complete servers to support more drives. Unfortunately, sticking to a tower type case costs more than a rackmount if you're building maxed out arrays. Buying the 4 x 5-into-3 and 1 x 4-into-3 hot-swap bays to max out an unRAID array in a tower case costs more than a Norco. The big rack cases are just the easiest way to do these large arrays. As for putting another case beside your current one. The drives connect via SATA cables. Use longer cables or get SAS adapters so you just run a SAS cable to connect the enclosures. You can also use a port multipier and connect 4 or 5 drives in an external box. Check out Addonics for lots of cool parts to do this kind of stuff. You could also get "cute" with your current disks, like putting 2 x 2T into RAID0 arrays and presenting that as a single disk to the server. I know the SiL3132 chipset will work doing this but I'm not sure if another RAID card would work this way. This approach is ideal since you're creating a higher chance of having an unrecoverable disk failure. It might make sense to add-in a few 2T drives into a newer array with 4T drives. Toshiba bought the Hitatchi 3.5" HDD business and the Toshiba 1T to 3T drives are just appearing now at decent prices. So, Toshiba might start selling the ex Hitatchi 4T drives for more reasonable prices too. So, it might be a good idea to hold off on storage purchases for a bit and see if this happens.

The Canadian price is $149 and I'll take the $129 2 year warranty Toshiba aka Hitachi drives over these.

Try going to the utils page and running the new permissions. If (once) that works, fix your Transmission install so it downloads with the proper permissions.

You might have just had a controller or connection issue. You could first try this and see if the drive is still OK. Stop the array. Unassign disk2. Start the array. Stop the array. Assign the same disk back as disk2 again. Check the status. It should say a start will rebuild the contents of disk2 onto the new drive. If it looks good, check the "are you sure" box and start again. It all goes well, disk2 will be working again and then you can worry about upgrading and using that 3T drive. If it goes badly, disk2 will red-ball again.

I'll be seeing them soon. I ordered 3 of them, should show up this week.

NCIX.ca is running a sale on these for $129 and they reportedly have a 2 year warranty. What the heck is the story with Toshiba HDD? I thought they were bought by Hitachi and then WD bought Hitachi. I went to storage.toshiba.com and there are drives but I didn't see anything about this model. I tried Google searching "Toshiba HDKPC08" but that didn't bring up any manufacturers web site info. Some info on the web says it's basically the same as the Hitachi drive. So, would you buy them? FYI, NCIX is also selling Toshiba 2T for $89 and 1T for $60. Edit - doing more reading, it seems for WD to buy Hitachi they had to sell the 3.5 drive business to Toshiba. So these are basically Hitachi 3T drives. Maybe I'll have to pick a couple up.

You could have stopped the preclear and initialized the array and started it again. It would do a parity sync but the parity would actually still be OK since the disk is cleared. I'm pretty sure that version of the script did clear the drive, it just doesn't do the post work of setting it as cleared and ready to use. There is an option in the script to clear only. It would cut the time down to about 1/3 compared to running the full 3 passes.
