  1. Hello. I have an Areca ARC-1260 16-port controller with 15 (currently) Seagate Barracuda 1.5TB (all drives are model "ST31500341AS" and this array has been running for 3 years) hard drives in a single Raid-6 raid set. This morning one of my drives dropped from the raid set. I removed the drive and validated it was bad through SeaTools. I have an extra Seagate 1.5TB drive (same model number) that I put into the system and connected it to channel 5 (where the drive failed this morning). Instead of the drive showing up as free (and I could then create it as a hot-spare and the array would start building), the drive is showing up as 1 drive of 15 in a second raid set that has the exact same name as the read raid set - "Raid Set # 00". From what I can tell, I will need to delete the 1 drive raid set, however when I go into the "Raid Set Functions", "Delete Raid Set", all I see is both raid arrays and they have the same name... Is there any way to fix this? I could guess which of the two identically named raid sets is the one with just 1 drive, and delete it, but if I guess wrong I will lose 17TB of data... Under the "Information", "RaidSet Hierarchy" option, I see the correct array with 14 drives - degraded as the first selection, and the failed array with the new drive I just put in as the second in the list. Any help would be greatly appreciated. If I did delete the wrong raidset, is there any way to recover it without losing data? Thank you so much for reading and any help you can provide...!
  2. Contacted Areca support here in the US and Benjamin was a great help. After updating the firmware on my ARC-1260, I was able to see the number of drives in each RaidSet. From there I deleted the bad RaidSet with only the new drive, marked the new drive as a hot spare, and the array started rebuilding.
  3. I am in the process of setting up a new raid6 array using an Areca ARC-1120 raid card and 8 Seagate 3TB hard drives. Currently I have 2x 16 drive Seagate Barracuda XT 1.5TB arrays (both with Areca ARC-1260 adapters) that have been functioning fine for going on 2 years. Based on this and how hard drive prices have skyrocketed I purchased 8 of the Seagate Go-Flex 3TB external hard drives during the BF sales. Upon opening 6 of the cases (2 won't be delivered until later today) I found 4 Barracuda XT 3TB drives and 2 of the new Barracuda ST3000DM001 3TB drives. Having had success before with the Barracuda XT drives in Raid6, I didn't think it would be a problem setting up the new array, but the "new" 3TB drive has given me pause and I need to understand if there are any firmware differences that would make using them in a Raid 5/6/10 array a problem. Does anyone know if there are any issues with this "new" Seagate 3TB drive being able to run in Raid 5/6/10? I do understand that both Areca and Seagate don't "support" Raid 5/6/10 on these drives and recommend the enterprise drives, but with hard drives prices so high right now these drives are all I can afford for now. Since this isn't a "green" drive my hope is that there isn't anything like WD's TLER in these new Seagate drives that will make Raid 5/6/10 arrays crap out like the WD Green drives do. Any help would be greatly appreciated. Thanks! -DC

    TLER / CCTL

    Here are some new drives to add to the list: Seagate model=ST33000651AS Size=3.0TB RPM=7200 Revision=? Firmware=CC45 Available=YES Default=Disabled Reboot=Stay Powercycle=Lost Seagate model=ST3000DM001 Size=3.0TB RPM=7200 Revision=? Firmware=CC96 Available=NO I'm not happy with these new Seagate 3TB drives (model ST3000DM001) as the smartctl -l scterc *drive* gives "Warning: device does not support SCT Error Recovery Control command" I hope this helps.
  5. Update: I just ran smartctl against the Seagate ST3000DM001 drives and they report: "Warning: device does not support SCT Error Recovery Control command". The Seagate Barracuda XT drives do support ERC, but it is disabled by default. I'm not sure if my Areca ARC-1120 card needs to have ERC set or not. Either way I guess I won't be using the new ST3000DM001 drives in anything other than Raid 0 or Raid 1. Thanks.
  6. I need to trace the connections to determine which drive is connect to which port, but here are the temps: HDD_01 - 36c HDD_02 - 47c HDD_03 - 35c HDD_04 - 47c HDD_05 - 34c HDD_06 - 43c HDD_07 - 35c HDD_08 - 47c HDD_09 - 37c HDD_10 - 34c HDD_11 - 42c HDD_12 - 41c HDD_13 - 42c HDD_14 - 41c HDD_15 - 38c I don't know how this compares with others, but I don't think it is too bad considering I'm using the stock fans with 2 8cm additional fans in the back of the case and my environment (mechanical room) doesn't have its own cooling so it is same temp as the house. As for the other Lian-Li case, it does look nice, but from what I say you will only get 15 bays and I'm not sure about the back top part of the case - can it hold additional drives? As for build quality, Lian Li is excellent! Have a good one, DC
  7. Help! I am trying to get my new raid array up and running. Goal: have the 16 1.5TB drives setup in a Raid6 array to provide maximum amount of raid 6 protected disk. Setup: Areca 1160 16-port SATA raid controller, 16 x 1.5TB Seagate hard drives, Windows 2008 Server (32-bit), on an Asus P5N-EM HDMI mobo. I used the Areca beta Windows 2008 driver - 6.20.00.15_80129. I created the raid array in the Areca bios to use all 16 drives and raid 6. In Windows 2008 created a "New Simple Volume" and tried to format it NTFS with 32K allocation unit size. Problem: Tried to format 19.1TB twice - system locked up each time. Once was a blue screen (didn't get the full message - but it was an IRQ Not Less or Equal) and the other was just a blank screen with mouse cursor (format takes 96 hours). Question: Can I do a quick format of the partition to get it online, and then use a tool (what tool I don't know) to do what a non-quick format would do? Any help or pointers would be greatly appreciated. -DC
  8. I am using a LIAN LI PC-V2000B PLUS II. I got the first one from Newegg.com and the second from Mwave. It looks like Newegg has these back in stock without PSU for $199. I've been building systems for 14 years and this is by far my favorite case. Here a picture: I'm using an Areca Arc-1160 Raid6 card. Thanks! What kind of case/tower are you using? I ended up using drive 16 as a hot spare, so the timing was a little off. It took right at 8 hours to create the Raid6 array in the Areca Arc-1160 card bios/setup, and then the format in Windows Server 2008 took 91-92 hours to complete. Total formatted capacity: 17.7TB Thanks!
  9. Finally got this raid array up and working...! Turns out that the firmware issue on the Seagate 1.5TB drives was causing the issue. Got all 16 drives updated to SD1A firmare and the raid array created just fine and has been running without any issues for 7 days. Thanks to everyone who helped out - I sure learned a lot doing this! -DC
  10. I will check that out - thank you very much! -DC
  11. Update: The quick format does work and I am presented with a 19TB formatted volume. I copied 10G of video files to the new drive and they played just fine locally and across the network. I am currently running the Error-checking tool built into Windows 2008 Server, but I don't think that will be as thorough as I would like to see. Any suggestions on tools to check the volume would be greatly appreciated. -DC
  12. Windows 2008 Server did not ask me if I wanted to use GPT - it just assumed based on the size. I say this as I originally tried this array with Windows Vista SP1 (32 bit) and it did ask if I wanted GPT which I tried. Failure to format the drive under Vista was my fault as I didn't specify the allocation unit size (default for NTFS was too small IIRC). I can try to create a volume smaller and format it, but my main question besides looking for advice on what I am trying to do is - can I do a quick format and then test the volume with a utility to basically do what the normal full format command will do (IIRC it validates all of the disk - doesn't just create the FAT table - or whatever it is now with GPT). Thanks everyone for replying so far - I am very grateful! -DC
  13. The Areca bios did recognize the 1.5TB drives, and was able to create the single 16 disk raid 6 array (19.1TB). I have not checked the bios version level for the Areca 1160 card - I'll do that later tonight. Thanks! Is this a personal preference, or something that I should really look at not doing? I wanted the 16 drive array to minimize the overhead that the array would need, and went with raid 6 so that if I do lose a volume, I can still be protected while it's replacement is rebuilt. Thanks! -DC
  14. Woohoo!!! The chkdsk worked like a charm. All the data is there (1.2TB). Thanks for the suggestions and all the help! -DC
  15. Last night one of my Raid5 arrays (4x650G drives on a Gigabyte Nvidia 630 chipset - onboard Raid controller) had an issue. On rebooting the box and going into the Raid BIOS I found that one of the four drives was not in the array and the array was in degraded mode. Without initially trying to rebuild the array I rebooted the system and came up in Windows (XP SP2). The degraded array did not show up. After rebooting again and dropping the 4th drive that was not in the degraded array, I then chose to rebuild the array and added the disk back in. Since the server is remote (i.e. not at my desk) I let the server finish coming up and tried to remote control it - no luck. Turns out that Windows XP was running CHKDSK on the array. I aborted (reboot) and brought the system up - skipping the CHKDSK. I used the Nvidia Mediashield software and found that the array was rebuilding. Fast forward to this morning - the rebuild is complete but the array shows up in Disk Manager as an empty partition. I rebooted the system again - Windows again wanted to do CHKDSK - I skipped it, and Disk Manager is still showing an empty partition. The array shows Healthy in the Mediashield software. So my question is - is there anyway to get my data back or is it gone? Any help would be greatly appreciated. Thanks, -DC
  16. Thank you so much for the information. When I did the rebuild there were no extra options (the nVidia raid software is pretty primitive). I will definitely reboot and run the chkdsk. I'll post the results when it is done. Thanks again! -DC

    RAID questions...

    Thanks for the info. I think that sounds like a reasonable precaution! -Devin

    RAID questions...

    I've setup my first RAID-5 array - 8x300G on a 3ware 7506-8 card. It is running beautifully! Thanks for all the help! I've purchased a 3ware 7500-12 card and have 12 Maxtor 200G drives to put on it. I am currently running Windows XP Pro SP2 on this system. I want to create a second RAID-5 array, but have a few questions: 1. Why/what is the 2TB limit I keep reading about on this site and 3ware's site? 2. Considering the 2TB limit, will I be better of doing 12x200G or 11x200G? I want to get the most storage out of my drives - i.e. I don't want to waste space. I'd even be interested to see if the card could do 11x200G with 1 200G spare... 3. 10 of my drives have 8M cache, and 2 have 16M cache. Is there any issue mixing these in a RAID-5 array? Additionally, I have 8x120G drives (various Mfgs), and 8x160G drives - all WD. Can I setup a RAID-10 with the 120G drives even though they aren't by the same MFG? If it is possible - is it advisable? I think that's it for now. Thanks again for all your help! - Devin

    RAID questions...

    Thanks for the info! It's nice to know about the 2TB limit. Any ideas on what the yield would be for a 12x200G vs 11x200G RAID-5 array would be? I just want to understand the difference so that I can make the best use of the drives.

    How big is your array?

    Individual disks right now: 8 x 300G Maxtor PATA 16M 2 x 250G WD 11 x 200G - Mostly Maxtor/WD 9 x 160G WD 8 x 120G WD 2 x 100G WD 2 x 74G WD Raptor Total: 7,848G Amount used - Approx 4,200G -DC

    Computer Engineering

    I think it is a very good idea to spend some time getting your GE's done, and probably the most helpful suggestion I have is to look into any programs that let you "shadow" someone in a field that you are interested. I know that my local University in conjunction with areas businesses allow students to spend a day "shadowing" someone as they go about their daily activities. If this isn't available in your area, look into intern positions. Getting a good look at different career choices before you commit to a lot of time and effort in an educational path is invaluable in my mind. Good luck! -DC

    Motherboard integrated RAID5 performance

    Peter, I'm in somewhat of the same boat that you are. The biggest question in my mind hasn't been asked yet - what type of disk activity will the RAID5 get? In my case I'm looking to build a file server for video files ranging from 200M to 4G each. Once I do the initial write, the file will never change. In this scenario a RAID5 setup without a dedicated processor for the parity calculations is more acceptable as the performance hit would only happen on the write of the data and then then file stays the same. If you are looking for a RAID array that will have a lot of write activity, either go with a 0+1, or get a dedicated RAID5 controller with the parity calc onboard. You could also look at 2 arrays - a smaller one using RAID 0+1 for frequent write activity, and then an onboard RAID5 array for larger files/data that won't change. Good luck and post what you end up doing. -DC
  24. First - THANK YOU for replying! I greatly appreciate it! You are totally right about it being a "mess of drives". After a weekend of weighing options, I'm planning on selling all drives 100G and below, and look for some good deals to replace the actual storage. This makes the most sense, and I've got enough room currently to be able to do that. After further reading, I think RAID5 is about the best solution that I can see that wouldn't cost a lot of money, and give me what I want the most - a large amount of space in a single LUN that can survive a single drive crash. I appreicate the info on the length of cables. I am currently using the NTFS mount option on most of my drives into folders, but with such small drives it really is a pain to administer. Thanks again! - Devin
  25. Hi everyone! I've been lurking for a while, and now I am looking for some help. Here are my questions: 1. How long can a IDE cable (PATA) be without issues? I've seen 18", and a mention of 36"... 2. Is there any way to "combine" multiple independent PATA drives into a larger volume in Windows XP or Server 2003 without using RAID, and the loss of a drive won't destroy all contents of all drives in the group? 3. In a RAID setup, do the drives have to be the same MFG, or can you mix? Looking at RAID5. 4. Anyone know if RAID5 on the Abit AT7 Highpoint 374 controller is reliable? It would be software RAID5... Here's my hardware: 2 file servers w/ Abit AT-7 mobo systems w/ dual RAID controllers in 12-bay cases (AT7 can do 12 drives) 2 large server cases - 6 5.25" ext., and room for 6 3.5" int drives 1 9-bay Firewire tower (http://www.censuspc.com/product.php?productid=644&cat=71&page=1) 4 workstation PCs - various mobos/drive configs 59 PATA drives between 60G and 250G 14 x 60G 14 x 80G 2 x 100G 8 x 120G 9 x 160G 10 x 200G 2 x 250G My Goals: 1. Attach as much of my storage to my two file servers 2. Have some of the drives in RAID5 for protection (i.e. the 160G and 200G drives) 3. Keep the number of "volumes" minimized as much as possible - i.e. combine drives to make larger volumes. 4. Best balance of keeping costs low while trying to achive the goals as best as possible (buying all new larger SATA drives isn't an option!) The servers are going to be for audio/video storage (music, AVIs, DVD rips, vid caps, etc) for use with a HTPC system (or two, or three...). I'm been looking at some PATA RAID5 controllers, but without a larger server case I'm stuck with either multiple systems as file servers, or using a 2nd case and use cables between the boxes. Sorry if this was too much for a first post. Thanks for looking, and let me know of any ideas/suggestions/etc. -DC
