We have a WD Passport, and whenever we connect it windows sees it and installs whatever's necessary; however, it never shows up as a drive. When going to disk management in the computer manager, the drive is listed but when trying to do anything with it we get an error saying it failed to initialize. Do you have any linux experience? Testdisk and photorec might work here.

Like the last two people said, i've successfully used ddrescue http://www.gnu.org/software/ddrescue/ddrescue.html to get data back. There's atleast two kinds of "lost everything", physical problem (bad sectors, bad circuits) which means anything you do is a risk to destroy the disk even more, or logical (lost file allocation table / mbr / whatever) where you can actually do get most data back. In the latter i'd atleast try to run ddrescue on it. I never documented what options i ran with so i can't help you more than that.

Is there a "go-to" card to just get a ton of SATA ports for a Windows system cheaply? With Server 2012 going RTM early next month, I'm thinking about migrating my two w2k8r2 software RAIDs over to use Storage Spaces instead. I've got 2 5 bay ICY Docks in the case right now with room for a 3rd and would like to all the drives on the same controller card if possible. So I'm looking for either 10 or 15 total ports as a minimum. I also want SMART capability in Windows (my current card doesn't seem to support it) Cheap but not crappy is what I'm looking for here...  edit: Forgot to say I want PCI Express.

Thanks for the suggestion! Sorry if I'm slow here, but I've been out of the controller hardware game for a loooong time. I did a little bit of searching over my lunch break and it looks like since the card just has 2 SAS ports, my options would be a couple SAS to 4 port SATA cables (8 drives total) or I would need an expander to get 10-15 connections out of it? The manual doesn't have much info about the expanders, but lists an "LSISASx12 Expander". The only thing I've found for sale with that search term is this and it looks like that is just the chip, not an actual board. I did find some forum posts pointing to a HP SAS Expander and this Intel Expander as being compatible, but at ~2-3 times the cost of the m1015 for one of the expanders I think I would compromise on doing a single card and just do 2 m1015s instead. Am I on the right track here?

Fancy_Lad posted:Thanks for the suggestion! That's pretty much it, yeah. The m1015 is popular because it's dirt-cheap on eBay from decommissioning, and it's normal to let ZFS/mdraid/whatever handle the actual drives anyway The equivalent LSI version is substantially more. The Intel/HP expanders are great if you want to pony up for a card with hardware RAID5 (the m1015 does not do it without some sort of fob that costs more than the card) and make a huge RAID5/6 across >8 drives, but if you're handling it on the OS level, just get multiple m1015s and deal with it in Windows/whatever.

I believe the m1015 also supports >2TB drives while most of the longstanding LSI based cheapo controllers just can't and there's no expectation of a firmware update.

Is the M1015 a PCIe 2.0 card, x8? My major complaint about my LSI1068E-based controllers is that they are 1.0 x8 cards, meaning they eat up more physical slots than they should on a modern mobo (i.e. I could get away with a single x16 2.0 slot worth of bandwidth for 3 of the fuckers instead of consuming 3 x16 slots).

On one hand, yes. On the other hand, stop being a bitch. It's a NAS. Maybe you'll put one in a virtualization server. It shouldn't be hogging lanes from your sweet graphics card which isn't in the same chassis, and if you're in the realm of FC or IB, you shouldn't be worrying about eBayed HBAs. You can comfortably drive a Norco 4224 (and maybe 2, if you want to get expanders) on a bog-standard mobo with 2 16x slots.

evol262 posted:On one hand, yes. No? I have 24 drives to connect, and each 1068E drives 8. That means 3 x16 slots (you don't really get many x8s on desktop boards), so I bought a X58 board. I would have used a 6-series board, but at most you get 2x8 slots, and I didn't really want to shell out for a Supermicro board (which would have been based on the 5500 anyways, if I recall correctly). And my NAS graphics are provided by a bitchin' Matrox G200.

The mobo for my file server is an old Gigabyte 780G board that has some crazy PCIe slots. One of the PCIe x16 slots actually only runs at x4 and shares bandwidth 2 other slots. Guess I have some research to do to see if 2 m1015s will even work on it or not...

The perfect board in that case will be a board that can do a 2x8 split, so pretty much every board intended for some type of SLI or CrossFire. On Sandy Bridge, the x16 PEG port can be bifurcated into two x8 links, perfect for your usage. Ivy Bridge has more options because it has a Gen 3 root complex, but since the majority of peripherals outside of GPUs are still PCIe 2.0, it's likely those mobos will also have the PEG link bifurcated to two x8 links. PCIe 3.0 doubles bandwidth again, so technically, if you throw a PCIe switch into the mix, you could run a retarded number of drives off one system. Even with PCIe 2.0 and mechanical drives on SATAII, you could end up with at least 32 drives running off the x16 PEG link. e: Your board will run one M1015 at full-speed (x8, 4Gb/s), and the other at half-speed (x4, 2Gb/s). With mechanical drives, you should be a-ok.

I'm looking to replace my HP Home Server with a NAS. I just want something that's easily compatible with both Mac and Windows platforms and will connect to an Airport Extreme with little fuss. Will also be connecting a Western Digital streamer to it to watch ripped movies on my network (DLNA streaming). I've looked at the Synology line and they have great reviews on Amazon. Any advice for something reliable and easy to use in the $200-400 range?

Synology is a good choice, but QNAP is also worth looking at. Every time I talk with people about NAS (not DIY solutions, mind you) it comes down to Synology or QNAP. Speaking of Synology, does anyone remember the package repository that was linked in this thread at some point? Apparently I didn't bookmark it, and I can't find it again (tried searching with threadid: and various keywords, but with no luck).

Without consulting this thread, I went and made the decision to use a PogoPlug for my network storage. In the past I have used a combination of a Segatte BlackArmor NAS, a cheap chinese usb network share device, and a PC sucking watts so I could watch stuff on my PS3. I had read about the PogoPlug a couple years ago. I was looking for a tiny, lightweight, linux box. I read about it running samba, and doing all the funny things you expect of a network services machine. (like the old Qube devices..) Well, tonight I had a bit of a "you didn't research this enough" moment. Shockingly, the PogoPlug didn't do all the wonderful magical things that I expected of it. So, while we're at it, here's what it looks like in service:  I have a 1.5tb disk on it now. With some others to join it shortly. After plugging in the pogoplug, and going to the website. I had my new cloud device running. I tried to mount it with my laptop. (yeah, yeah, yeah, giggle.) And while I found a media server, I found no way to mount the drive. So while poking around on the setup interface, I found that I had the choice to setup a superuser password for SSH access. Well.... That's an invitation I can't resist. code:Which means I now have a tiny little low power linux file server running in my computer room. Which, I suppose, isn't far from what I had with my BlackArmor NAS. Except I have root access to it. Oh, and while I am at it. I should mention total cost. The Pogoplug was $36, and the drive was $85.

I just got in my new set of disks and am trying to decide the best way to go about upgrading from my smaller harddisks to the larger. The easiest way is to simply swap the disks, one at a time over the course of a couple days until all the rebuilding is done. Viola! More space. This is hampered a bit by my desire to upgrade the system in general. I would like to reinstall the OS and upgrade the version of ZFS I am using. Right now I'm running some really old version of OpenSolaris and I'm not terribly pleased with it. I would prefer to switch to FreeBSD I think - I've used it before and I find it a lot more comfortable to work in/keep up to date/etc. To complicate things, the current drives are running some really old version of ZFS - I was asking earlier in this thread about backups and people mentioned deduplication... My version of ZFS must be <v21 because it doesn't support it  I'm thinking now would be the best time to make a clean break. I don't really want to lose a bunch of data through experimentation (I'm going to back up the critical personal stuff but there is a lot of other stuff that isn't really worth backing up, but I would also rather not lose) so I'm hoping to kind of bounce a few ideas off of you guys and see what you think. My machines root file system exists on a harddisk separate from the storage disks which should simplify things. I should be able to export the zfs (pool? i get my zfs lingo confused), install freebsd, and then import the storage harddrives in the new OS. Would I be able to upgrade ZFS versions in place? if that is the case, I could upgrade the filesystem, swap disks, and be good to go I think. If not, could i run the old disks on an old version of ZFS and make a totally new storage set with the new disks and just copy stuff over? I'm not sure if the machine has enough SATA ports for that, but I may be able to get something figured out. Am I missing some easy method or approach to this? I also need to replace the case because the USPS totally destroyed it (I really liked the Chenbro ES34069 before it got smashed up), and could potentially drop a few more dollars on an overall hardware upgrade. I'm hoping switching to FreeBSD will make it easier to make the server a bit more multipurpose so having a better proc/more ram may not be a totally bad thing. If that ends up being a 'good idea' I could easily just build the new box with the new harddrives and copy everything over across the network. Time consuming, but safest.

Hard drives have their highest failure rates in the first six months, then they drop, then they raise again slowly each year until, at about five years old, they fail as often as six month old drives do. After that, it gets even worse.

My DNS-321 is a piece of poo poo that constantly crashes and I'm going to take a hammer to it out back in a few minutes. After removing the disks of course, but then I think they might be tainted or something so maybe I should leave them in  Anyway, it needs replacing. While I mull over what to get for my two 1TB disks though, I have some questions. - In RAID 1, if one disk dies can I still immediately access all my data on the other one or do I need to replace the dead disk first? - What's the normal process for upgrading available disk space in RAID 1, like if I were to buy two 2TB disks? Can I just replace one disk, let the NAS re-mirror the other old disk to the new one, then swap out the second old one? (that sounds a little too easy even as I write it )- Am I basically hosed if I don't want to spend more than $200 on this? I know people recommend things like the ReadyNAS Ultra stuff but that's like $350 where I am, and I don't especially want to wait for online shipping anyway.

I have an ancient HP Mediasmart EX487 server that I haven't used in over two years. I fired it back up today so I can get my old files (obviously not important at all) off of it so I can get rid of it. I cannot, for the life of me, connect to it. I connected it to my laptop via ethernet, used remote desktop to log-in and I don't seem to remember the name of the server. Tried Admin, Administrator, and two names I'm positive I assigned to it. No dice. I also installed the Home Server Connector software and it never found it (even when connected to my router). Not once have I found it on any network search on my computer. I tried to find it by typing in random addresses (192.168.1.12, etc) but no dice. I rebooted the server and my laptop a few times in the process just in case. Nothing. It's as if it doesn't exist. Anyone have a tip as to how to find this thing on my network/RDC so I can access then wipe? hotsauce fucked around with this message at 05:52 on Jul 22, 2012 |

Do you have access to the dhcp server? if you have a wireless router or something you should be able to login and see if it grabbed a lease. If it's statically assigned, you may have to sniff traffic with wireshark or something to see if it's showing up. Assuming it's even booting properly and everything.

Haha man, that sucked hardcore. I tried to retrieve the data off of the harddrive that I had posted about earlier. Before I could run ddrescue, I had to mount my raid array (my main OS drive didn't have enough space). I'm not completely new to linux but I had never done anything like this. I found a tutorial online (from the distro's forums) and went ahead to try to mount it. Well it definitely didn't work. Booting back into Windows, I was greeted with a prompt to rebuild my raid array (raid 5, not the first time I've had to rebuild it). 10 hours later all of my data is gone  . I guess there's nothing wrong with starting from scratch, right?  And, the hdd that I was trying to retrieve from is actually completely dead. Ran some diagnostics and the entire thing just threw a bunch of errors.

Will an external driver reader read the drives? I just want my data off of it.
