Data Recovery Service in Zurich

Hi all,

I'm a bit lost looking online. I have a NAS Hard-Drive that won't start-up anymore, and I don't have the necessary hardware to sort it myself.

I'm looking for a reliable and affordable technician or company that can pull the files off of this drive and put them on a different one I have already bought.

The companies I found online seem more business-oriented, rather than for privateers.

Do you know what is a good place to look?

Thanks!

Re: Data Recovery Service in Zurich

If the disc itself needs to be put in another housing i would suggest a proper company doing so, this needs to be done in a fully clean environment and the smallest error can cause big problems with your data. Most companies doing this also provide services for privateers.

The clean environment is also the reason why most normal computer stores don't provide such service.

If it's an external one that does absolutely nothing you might first consider putting the complete harddisk itself in another casing. If it's an internal that remains fully dead then the solutions for you to repair this yourself are almost zero.

PS: In future always make back-ups of things you don't want to loose. There's only two options with HD's either you stop using it, or it will break down.

Re: Data Recovery Service in Zurich

Before you spend any money, try this first:

Put the drive in a large ziploc bag and seal it (airtight).
Put that in the freezer overnight.
Take it out and allow it to thaw (takes about 6 hours).
Remove from the bag and plug it into your computer/nas with copy/cloning software and a disc (with enough space to take the full capacity of the dead drive) already installed and ready to go.

Start the computer/nas and clone/copy the disc.

I've had reasonably good luck with both laptop and desktop drives which have died... more so than swapping drive electronics from an identical drive.

I guess you could put a handful of rice in the ziploc before freezing it (to absorb moisture during the thaw out), but I've never bothered - each time I've done this the disc was running recently enough that there wouldn't have been any moisture inside the enclosure anyway.

Not trying to boot and run an OS from the dead drive means that there is a lot less going on, and cloning software reduces the drive activity to a minimum as well. You only need it to run long enough to get the data onto another drive.

And.... get a NAS which is at least RAID 1. Raid 5 is even better. When a drive fails you've still got your data, and you just note which drive it is, buy a replacement drive, pop it in (usually without even having to shut the NAS down) and it just rebuilds the array on it's own.

RAID 5 is a very bad idea with modern disk sizes...
RAID1, RAID10 if you have drives bigger than 2TB.

Raid 10 for a SoHo NAS? You're kidding.

I run 2x Raid5 Synos with 4TB disks, One syno is live and it syncs to the older (ds411j). Performance isn't great, but it's a home storage system for crying out loud.

Since you're sceptical you could google some info statistics about rebuild time/failure ratio.

If you are interested in this topic, you can read few articles about RAID5, like this one :

P.S.
I own 6x drives NAS working in RAID10 with a constant replication to another NAS located in another country.

RAID 1 is OK if you have a single NAS and just 2 disk bays (I have DS-213).
If I had more disk bays and/or more NAS devices, I might do it differently.

Raid 5 also has a write penalty which would be important during, say, video editing.
Especially when you'd still have spinning rust drives in a NAS

Finally, RAID 1+0 has improved resilience agsinst multiple disk failures.
All drives in a NAS will typically have the same make, model and firmware so you have a single point of failure.
The truly paranoid will mix disks to reduce this.

I still follow the 3-2-1 backup rules.

In my case, my NAS is backed up to Amazon S3 for like a few USD per month

Both of them aren't really much safer than RAID5 - a wrong second disk fails or UREs and you're just as screwed, so your chance of failure is only reduced by a small factor = the number of disks. Is it really worth the tradeoff in available storage?

A very bad idea is not having a plan B, offsite backups, for in case something physically happens with your whole server, it catches fire or gets stolen etc. And not using a modern checksumming filesystem is also plain ignorance and silly these days with modern disk sizes and cheap powerful CPUs - hardware RAID mainly guarantees uninterrupted operation, but doesn't protect against bitrot at all

WADR, you're missing the point. OP has a complete data loss issue because it was single instance, single spindle - this wouldn't have happend with multiple instance or multiple spindle, or the loss would have been reduced with a backup to some other device.

My double NAS/RAID5 setup is already OTT for personal use: 6 NAS/RAID10/Offsite dupe is a whole other league.

My 411j is on 24/7 since 2006. I haven't lost a single file. It's about time that I faced the realities of thermal life on that MoBo, but I'll probably just run xpenology on a Microserver... that'll do me fine for another decade or so.

RAID10 is great. So is zfs, and whatever latest whizz bang stuff is available, but when the requirement is an inexpensive box in the corner which stores backups and seldom used data and doesn't make much noise... then perfection is the enemy of good enough.

Re: Data Recovery Service in Zurich

I run SOHO on 3x5 RAID10 (3-way mirror of 5-disk stripes, 10 TB netto on 15 2-TB spindles). And backup daily to another mirrored disk pool. And sync deltas to another datacenter twice per day.
Consumer-grade disks are cheap, but better have alot of redundancy.
Coming back to topic:
Putting the drive in a freezer may be a good idea, but I'd do it after trying to clone first. The easiest is to connect it to some Linux machine which has another disk of the same size, and see if it's recognized at all, then run "dd" against physicals
What size is the disk?
Any idea about disk model? Interface?
What NAS is it in? (model)
Can you post some pictures of NAS and the disk itself? (the label and the connector)
I may have necessary hardware and spare disk, and connect/smoke-test for free (in Zurich Kreis 7)

Just to emphasise that,

RAID is not a substitute for backups.

If the OP had adequate backups, there would be no need to look for a recovery service in the first place.

A realistic approach with a box so old. I have completely gone off anything HP though. The Gen8 Microserver I bought last year not only came with a pre-expired warranty wrt firmware upgrades (half expected), but the 3 year on-site warranty package turned out to be pre-expired too, only valid for two and a half years.

As various vulnerabilities come to light, the best thing you can do with the ILO features of HP boxes in conjunction with out of date firmware is to disconnect the buggers (i.e. ILO port(s)) from your network.

Noise is certainly my enemy here. I used to run some pretty beefy stuff at home and the noise eventually got to me, especially in the summer months when to keep everything cool I was leaving doors open to get a through draught.

But backups are not not a substitute for RAID, either ))
Main purpose of hardware redundancy is to protect against data loss caused by hardware malfunction (broken disk)
Purpose of backups is to protect against human mistakes. Therefore, a good backup system should allow for point-in-time restore, not only last version restore, otherwise backup doesn't fulfill it's main role.

RAID for uptime.

Backups for data protection.
