I can say without a doubt that when adding the last 3 drives (three separate occasions), more than just the 1 new drive showed up as unformatted upon restarting the array after assigning the drive. I've only ever used 4.4.2 and 4.5.1 final releases. I know that the last two I've added have been under 4.5.1, I can't recall if the 1st of those three was 4.4.2 or 4.5.1. Given that I just used up my 6th and final MB SATA port, my next drive will require an add on card, which will likely be the super micro card that requires 4.5.3. Hopefully the next version will be out by then with the fix. (off topic, this next one will be expensive for me.....pro key, SATA card, and the drive ).

What version would someone need to drop back to in order to remove this bug? I'm running 4.5.1 and i see the bug.

i just replaced my parity drive and added the old parity drive into the array yesterday. upon preclearing my old drive and stopping the array and adding it to the list, when going back to the main screen, every single one of my drives showed as unformatted. i usually get 1 or 2 extras, but i had never seen every drive show up as unformatted. a quick refresh fixed it, but I agree, this is a monumental bug that needs to be fixed ASAP. (i'm running 4.5.1) c+h

thank you very much, Joe L. as always, you are the man.

I know I am worrisome over the SMART table outputs after running preclear, but some of the values look bad in my uneducated opinion (those in the last column....)

(this is going to be my new parity drive). thanks for any help, c+h

4.4.2 and 4.5 both have shown an "unformatted" status for a formatted drive (including those with lots of data). Haven't updated to 4.5.3 yet. A simple refresh usually corrects the error. Even though I've seen it more than a few times, it always makes me jump a little.

FYI $119 (pro) - $69 (plus) = $50. Pro Upgrade from plus = $59 ($49 with the current coupon). Show me a $30 upgrade and I will show you $30 leaving my wallet. $30 each is for 2 keys....most only have one. While I think it's great a cache drive was added to plus, I'd rather have an extra data drive than a cache drive. Write just aren't that painful, and my system writes slower than many. (Note: I am not complaining about the cost of unRaid. While I don't think it's cheap, I don't think it's expensive either. I'm just pointing out that $30 is nowhere in the equation for a pro single key upgrade)

yeah, what he said. (shameless Plus user bump ).

thanks for the help, joe, as I'm sure you have heard many times by now. I was confused because I never saw anything after running preclear on my previous 3 disks, including another one of the exact same make and model. I went ahead and switched the cable out last night and started preclear again. Guess I didn't need to. Silly me. Will happily add it to the array when it's done. Thanks again, c+h

Got a new WD 1 TB green HD, ran preclear_disk.sh on it, and for first time, saw preclear kick out an error when completed: < 1 Raw_Read_Error_Rate 0x002f 100 253 051 Pre-fail Always - 0 --- > 1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 0 58c58 < 7 Seek_Error_Rate 0x002e 100 253 000 Old_age Always - 0 --- > 7 Seek_Error_Rate 0x002e 200 200 000 Old_age Always - 0 63c63 < 193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 12 --- > 193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 15 67c67 < 199 UDMA_CRC_Error_Count 0x0032 200 253 000 Old_age Always - 0 --- > 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0 ============================================================================ any help from those more knowledgable than I? Thanks c+h

why a full blown C200 then? an A-110 would do just that for $100 less (and take up less space), plus you get it right away. A C200 gets you the ability to play unaltered blurays and a fast processor for a better interface, but the product isn't really developed. The C200 will be a work in progress for a while, just like the A100 was for a while. My A100 plays everything I throw at it, except the killa sample, which isn't indicative of real world encodes.

In terms of the math and calculating probabilities of failures....How is the URE rate calculated by these HDD companies? Is this the average URE rate? Is it the 95% confidence interval rate, etc? Numbers usually only mean something if you know how they are stated. A bag of M&M's says it has some number of ounces of candy in it, say 3 ounces. very few bags will have *exactly* 3 ounces, but they set up the packaging systems such that some percentage of M&M bags will have 3 or more ounces (95%, 98%, 99%, etc). The URE rate could be a 95% confidence rate as well, meaning 95% of hard drives will not see this error in, say, 1x10^15 bit reads, but the typical rate could be several orders of magnitude higher. And of course that would mean 5% would be lower. Fun with statistics.

what are "these issues"? So far, "skipping" is a result of encoding with the wrong settings that require excessive processing capbility (usually with no visual difference). Ever since they bumped the samba performance up to near 40 MBit, it plays most everything I throw at it outside of the "killa sample." Again, the current PCH can't process 100 Mbit/s of data, so even if you could magically make the older/current A-100's or A-110's have gigabit network interfaces....you still would be limited by the internal guts operating at less than 100 Mbit/s. Server ----> Network -----> PCH -----> TV/Amp Currently, the bottleneck is the sigma chip inside the PCH, unless your network is 10 MBit or your server is crazy slow (read: not unRaid). As far as technically, a C-200 could only make it worse since unRaid can currently give a PCH data faster than it can handle it. Theoretically, if the new C-200 could process data at a phenomenally higher rate, you could possibly handle data faster than unRaid could dish it out, but I highly doubt it.

To anyone looking at the Popcorn hour (A100/A110) - unRaid combination and are worrying about various bit rates moving files around, keep this in mind: The transfer rates a Popcorn Hour can handle over various protocols are: 1. NFS ~38 Mb/s 2. SMB ~38 Mb/s 3. Http ~42 Mb/s 4. Internal hard drive ~42 Mb/s Notice #4. Even with the file sitting right there inside the box, the PCH (A100/A110) can't handle any higher of a bit rate, so no network solution in the world capable of 42+ Mb/s is going to benefit it. The internal guts of the circuit board just can't handle it. The new PCH (not released yet) has Gigabit ethernet and a faster processor, so one could handle more throughput. For the PCH, unRaid should NEVER be the bottle neck unless you have some serious networking issues.

i'm currently running 1 parity and 1 data, though i have more than one share folder. I could have only 1 and it would be just fine. your files can be huge, just not over 1.5 TB (or 1 TB if writing to the 1 TB drive). Once I get my files off a current 1 TB drive in my desktop, I'll move it over to the array and have 2 data disks, but I'm not done doing that yet. Like you, I am planning on expanding my disk collection as needed.

There will never be "one cheapest build." The best way to save money is to be patient. Have an idea of a few different MB's, cases, PSU's, etc you have in mind and wait for sales. I've wanted to build an NAS for sometime, especially unRaid. Over the course of a few weeks, i picked up P5B Deluxe/e6600 C2D/4 GB Ram/Zalman cooler combo for $150 off craigslist. ABS Aplus huge case for $90 at newegg Corsair 650W single 12V rail PSU at newegg for $50 2 1TB hard drives for $110 at newegg (already have a 1 TB drive) $400 for 2TB backed up (just a start, will add HD's as needed, and SATA controller cards), plus i have about $30 in Bing cashback coming from those purchases. now if i could just buy some extensive knowledge of all those customizations out there for unRaid. I feel like I got higher end components for pretty cheap. Just wait for sales, then jump on them. watch places like fatwallet, slickdeals, anand-tech, here, etc for the deals to be posted. new ones on HD's all the time. I would imagine you could do way cheaper than i did if you bought bargain brands, but i've had good luck with paying for good brands over the years.
