  1. I have a RAID 5 array on an Adaptec 8805 (default stripe size used 256KB) that I just expanded by one additional 8TB He8 drive, all went well. But then I went into Windows disk management to expand the single volume of about 30TB by the additional 7.2TB. I get an error that it can't happen because it exceeds the cluster limit of Windows. I know that the default cluster size for Windows 7 for volumes of 16TB–32 TB is 8 KB and for 32TB–64 TB it doubles to 16 KB. I expect that is the issue that I have, crossing that threshold exceeds the cluster number limit. Is there any simple way to change the cluster size, perhaps with third party software rather than to delete the existing volume and create it again with a larger value and then have to copy all the data back from the backup volumes? Thanks.
  2. Thanks, that's what I thought. I do have everything backed up, just being lazy.

    Seagate Releases 14TB Drives

    5 or 6 of the Ironwolf Pros may be my next main RAID 5 array and relegate my 8xHe8 8TB to backup. Just need to double check that my spare Adaptec 8805 will play nice, which I assume that it will.

    HTPC 4k ultra

    I would never suggest using a consumer motherboard RAID controller, any simple bios hiccup/update/bad karma and poof all gone. I've seen this way way too many times. At a minimum if you do it, have easy to access backup and lots of spare time. One of my older storage arrays has 8 3TB Hitachi 7200rpm drives, 7 in RAID 5 plus a hot spare that has performed flawlessly for years. They were relegated to secondary backup storage a little over a year ago just due to age and a new array of 8TB He8 Hitachi drives. Those too have performed without issues.
  5. While both are about the same, just make sure that a USB external drive is not your sole backup and when using them on Windows machines use the safe eject to help avoid losing your data in a mishap, I second the motion on HGST drives. I have 20 in two arrays that have been on 24/7 for the past 4 years without a failure. Yup, I know that I just jinxed myself.
  6. As continuum said, if the data is really important and you did not have it backed up to a reliable backup, you are going to spend significant money. USB drives are an extremely poor single source backup as they are easily corrupted in many situations. Moreover, one backup for important data is about as reliable as no backup. EaseUS should give you a refund if the product did not work for you and you first used the trial version and it stated that it would recover your data.
  7. Agreed, and just remember to safely eject the drive and have the computer on a UPS with automatic shutdown software if you leave the drive on a lot -- USB drives are easily corrupted if disconnected during a write.

    Quiet hard drive

    Figure out which drives you are interested in and then get the pfd product sheet off their web site. They all include acoustic specs. For example WD Black 6TB is 29dB at idle and 36dB when seeking. All major drive makers publish these, but there is little difference in modern models although the HGST He8 drives are more quiet at idle at 20dB. There are 10 of those spinning within 5 feet of me and I cannot hear them over PSU and case fans unless they are doing a significant seek, like loading a large database.
  9. HGST calls it ISE and it is their version of the standard Sanitize (T10/T13) SATA command. So you would have to check if drives support those -- I do not believe that many consumer level drives include that feature at this time. I primarily use HGST drives for other reasons -- like their quality, but that is an available attribute on most if not all enterprise models
  10. You have already created a RAID 1 array from the 2 disks. If you want to change it to something else you need to delete that array and create what you want. Basic is their use of separate disks and what they call JBOD is really akin to RAID 0 (so no fault tolerance). You don't have any disk groups, a Synology disk group comprises of one or more drives combined into a single partition, which would be like RAID0 or RAID5..
  11. My experience with the 2.5" Seagates is good, but never rely on a single drive for backup. Anything important should be on other devices, preferably in other locations. And always be careful to eject the drive before detaching to ensure that all writes are done, and use a UPS on your computer so it doesn't power off during writes to external drives. Just a few of the fun ways that USB drives can hose your data, whatever the drive size.
  12. While with most controllers that I have used I would just delete the array and then recreate it as JBOD then run DBAN, some Dell servers won't allow that but apparently will allow you to set each drive as a RAID0 and run DBAN like THIS guy describes.

    Controller for 4 8tb sas drives

    If you are sure that you will not expand beyond 4 disks *and* your HGST drives are 512e (not native 4k) you could consider an Adaptec 6405. I have a 6805 with 8 x 8TB He8 drives that works quite well as my backup storage to a newer 8805 setup. While Microsemi (now the Adaptec owner) has only done limited drive testing, HGST has a more extensive guide for their drives HERE. At one time I investigated using 4K native drives with the 6805 and found information that it would not work but have since lost the link. Newegg has the 6405 (which is 6Gb/s that I agree is more than adequate if you only use spinners) available for $269 after promo code HERE and then you will also need one Internal mini-SAS with power (SFF-8087 to SFF-8482) cable that is a 1 8087 to 4 SAS fanout cable and runs under $20 on Amazon and elsewhere.
  14. Can anyone tell me if you get full 10gbs speed when using both ports of a card between the two other connected devices using the same cards and 5m appropriate cables?

    Anyone tried this product?

    I've used quite a few IcyDock products but not either of those. Their hot swap front case caddy is handy if you swap drives around a lot
  16. There are no video links on YouTube for what you need, assuming you must have the data you *must* use a recovery service that will open the drive in a clean room and attempt to copy the data to another drive. It is not guaranteed to work and if it does it is very expensive. Now read all of the responses again, and you will see a theme -- you cannot do anything about this yourself and to use a proper service will be very expensive. In the future you will never again forget the importance of good backup practices.

    512e or 4Kn Format

    Update. Things went very well with the new array. I used 5 8TB He8 512e drives and an Adaptec 8805 controller. I stuck it into my NAS box on the second x8 PCIe connector (the first has my old 6805 with 8 3TB in RAID 6), installed the Win 7 x64 driver and after the build was good to go. Took around 30 hours to build the RAID 5 and 14TB of data transfered from the old array to the new at 500-600MB/s.
  18. I'm looking at the HGST He8 drives for a RAID 6 array. Is there any particular advantage to using the 512e format or 4Kn format as both are supported by the Adaptec card that I am using? The 512e seem a bit cheaper in the 8TB capacity. Thanks!

    512e or 4Kn Format

    I selected the He8 for their reliability and needed a large space with as small a number of drives as possible, plus I got the 8TB drives for only $441 each. Enterprise quality (10E15, 2.5M hours MTBF) 8TB drives are not terribly common AFAIK and I have had excellent results with HGST enterprise drives since they first came out. I don't feel comforatable with the Seagate SMR 8TB drives yet, so they were not considered at all, and most of the Seagate offerings are only 10E14 drives with MTBF around 1M hours. The energy savings of the He8 will just be a bonus since they will run 24/7. So far I am very happy with the drives, and the Adaptec 8805 that I went with instead of the 71605 since i got it for over $250 less and really didn't need 16 ports. I'll give an update report in 3 or 4 months after the data migration is complete and the new array has had some service time.

    Samsung 2TB SSD: when?

    Why settle for only 2TB if you have the budget?

    RAID 6 writes have really slowed

    I got lucky -- second disk I pulled was the problem. Stuck in a replacement and rebuild is done. Not sure why maxView didn't detect it, but the card is out of warranty so no more support. Thanks
  22. I have an Adaptec 6805 with 7 3TB Hitachi 7200rpm disks in RAID 6 (Win 7x64, i3-2100, 8GB RAM, just a storage box no other tasks). 6-8 TB empty space still and updated to the latest firmware and storage manager software. Reads are as good as ever, but over the past few weeks writes have slowed to a crawl, like 20MB/s. All disks and the array indicate optimal status from the boot screen and storage manager software. It sure seems to me like a disk is bad, just hard to figure out since they all are listed as optimal. Any ideas on troubleshooting this? Thanks!
  23. Big sale on some LSI RAID cards at Newegg today -- I figured that it was an error but checked and it is 50% off the already discounted price for some models today 12/2.
  24. I have two of the 32GB models and they are great for those of us who are tough on things, mine have been through the laundry many times with no ill effect or data loss. Not intentionally, but the GF does not check pockets on laundry day.
  25. I'm running the latest Adaptec MaxView Storage manager on a 6805. I started with 4 3TB disks in RAID 5 but have expanded the array twice, now up to 6 disks. I want to migrate to RAID 6 but that option is not available adding one more drive (my current hot spare). Do I need to add 2 new disks to migrate from RAID 5 to 6 on my 6805? Thanks!
