Feets doesn't matter, it's the shock/impact that matters, specially when it's running. No running HDD will sustain 2-3 feet fall.
I never store anything permanent on an external HDD, for this same reason. All your important stuff should be on a non-portable place. with at-least one more copy on different location.
Now, when you get your NAS, don't be greedy and setup a RAID 1.
Backup is like Exercise, we always learn its value the hard way.

I learned that lesson, thankfully many years ago, I worked two weeks on a project got a printout and then went to copy to another floppy and mixed up source and destination and overwrote the work I had done. Luckily I had a printout and it only took me a couple of days to retype and correct before getting back my work. After that it was double backup.

Agreed!
RAID 5, minimum 3 disks, from different manufacturers if possible, if not then different batches. That way, that should fail at different times...
And keep the NAS on the floor!

What do you use for your NAS?
I got the following hardware just haven't set it up yet.
Asrock B75M R2.0 M/B with 3 x SATA3 and 5 x SATA2 ports
Pentium G2120 CPU
2 x 8GB G.Skill Ripjaws-X DDR3-2133
3 x Western Disgital 2TB Caviar Black HDD
5 x Seagate Barracuda 3TB HDD
Planning on running FreeNAS 9.1 and having 2 separate RAID5 arrays. The 3 x WD 2TB will be iSCSI targets for virtual machines. The 5 x Seagate 3TB will be network storage for Movies, TV shows, ISO's, software and family data.
Got anothe Asrock B75M R2.0 M/B, Core i7-3770 CPU and yet to get another set of the G.Skill RAM mentioned above so I can setup my server. Hoping to run VMware ESXi 5.1 as the host, but if I have issues with the hardware will have to play with Windows Server 2012 and HyperV.

Acer Aspire Easy store with 4 x 1Tb HDD. It's a few years old now, but it has power management and intelligent cooling, so it spins the disks down when they aren't in use which preserves the bearing life, and Works well to keep the temperatures nice and cool.
And it's a damn sight quieter than the NetGear ReadyNAS I tried replacing it with a couple of years ago. Plus that was way, easy too fussy about it's drives - it wouldn't accept two of the new drives I got at all. Big plus it had was hot swap, and automatic upgrade if you added a clean disk.

How much power does such a NAS consume? (In use, and stand-by)
I was considering buying a NAS for storage but I'm a bit concerned about an ever running "server" in my home

Depends on the make and model - but most manufacturers will quote it. The more disks, the more power!
It's not that bad: certainly less than the equivalent PC because it's dedicated hardware rather than general-purpose. So the processor is "enough for the job" and no more, and so forth. Plus there is no graphics (it's all configured via HTML through your browser) and if it spins down your disks and hibernates itself (as most do) then the power is "just enough to wake-up on LAN" or similar.

If you want higher performance and flexibility, build your own NAS, but if you want hassle-free and stable solution buy ready-made.
I am using D-Link DNS-321[^] ($60.00) since 4 years now, no problems so far. It is not as quiet as it should be, and the file transfers are slow (14 MB/Sec MAX). But it is very stable, haven't restarted in years. Feature set is also very impressive. Compatible with almost every device I own (Tablets / TV / Phone / PC / Mac).
There are other very good solutions are available, but since all my network components are D-Link I bought D-Link NAS. (i.e. Synology DiskStation)
I used it as a media server, so that I can watch movies / tv shows from any device at my home. It works great.
This is the newer model of it, D-Link DNS-320 ShareCenter[^].

That's interesting (14 MB/Sec MAX).
I am working on a program that is generating over 2 TB of data. At a transfer rate of 14 MB/Sec that would be:
219,023,255,552 BYTES
149,796 seconds
2,496.6 minutes
41.6 hours
1.7 days
I guess that I should not try to back this up, especially since I make test runs several times a day.
Dave.
PS. And then my external hard drive (4 TB Seagate) refused to read one of the files during verification - CRC error), and these are just several months old.

The one I mentioned is for Home use, you should buy the business line of NAS products like Cisco / Drobo / Synology (they have much higher transfer speed). or if you have the budget then setup SAN.
Member 4194593 wrote: (4 TB Seagate)
After a lot of research I have found that we are not ready for HDD > 2 TB yet. The manufacturers are still struggling with the firmware to support higher density. And the most reliable HDD in the market right now, is the Western Digital Green 2 TB.
But you should try upgrading the firmware of your 4 TB HDD, if available.

I contacted Seagate. Some Script Kiddy suggested that I try chkdsk. I had already done that, but I tried again with the same result - no errors. I then tried a scan for bad sectors. It was scanning at a rate of about 1 file a second.
The drive had 374517 files
scan time 374517 seconds
6241.95 minutes
104.03 hours
4.33 days
I decided to kill the scan.
Still waiting for the next response.
I had asked about whether a single bad file this early indicated a surface defect. No response yet for that.
I allowed that I was renaming the directory with the bad file as "BadSpace", re-creating the directory, moving the good files preceding the bad file and the good files following the bad file to the re-created directory, then recalculating the bad file data (a 4 minute process vs 44 hours to rebuild all of the files), then never releasing the bad file to free up the bad space. No response yet for that.
I do not want to return the drive to Seagate under warranty, too much personal data, would take too much time to clear all of my personal backup data, and much to much time to secure erase the 374517 files. I'll just eat the bad drive if necessary and buy a new one.
Dave.

Depending on how much you value your collection, there are forensic data recovery places that will actually disassemble what's left of your broken hard drive (in a clean room) and recover the data... Very expensive option, though!!
|

|

If you're not willing to pay hundreds+ on recovery you can sometimes recover a clicking drive long enough to get data off by sticking it in the freezer for a while (differential thermal expansion moving parts around inside). It's only a short term-until it warms back up againbut should be long enough to copy stuff off option; and doing so will reduce the chance of any pros being able to get your data back.

Years ago I had an old hdd that's heads were stuck and was making a similar clicking noise. I strung it up (horizontally) and gave it a few good spins to appky some centripetal/centrifugal force and was able to recover some data off it. Worth a try at least. Google has some other suggestion for stuck hdd heads as well, although in your case it might be too physically damaged.

I was just told that I get to go to a client site for two days a week minimum. My biggest objection is not having dual monitors. How fantastic would it be if there was a laptop that had dual monitors built in. Has anybody ever heard of one, cause I would like to make it required equipment before I go there to work

Get a docking station and two monitors (client may have spare screens). or try to find Lenovo W700ds[^] somewhere.

That is exactly what I'm talking about! Now if it was only affordable. Either way, I just put in a purchase request for one. I know the response, but its worth asking
Hogan

I forgot to mention that It is a very old model (3-4 years old, I remembered because it is the only dual screen laptop), I don't think it's available for purchase now.
Also even if you can find one, in the same price you can get a docking station, dual 24" monitor and a whole new laptop.
