NAS200 · NMH305 · NSS322 · NSS324 · NSS2000
Cisco / Linksys NAS data recovery. Networking names that briefly made NAS.
Linksys made the two-bay NAS200 and the Media Hub, and Cisco after it the NSS small-business range, before both left the market. They are Linux with ext3 or XFS over mdadm, and they arrive after years in a cupboard with a dead supply or a drive that will not spin. A single-drive unit is £300 + VAT; a set is £500 + VAT upwards, in writing after the free look.

Describe yours to us →| What you see | The usual reason | Where that leaves you |
|---|---|---|
| Unit dead; drives spin | PSU or board | Drives imaged; set assembled from the metadata |
| Volume missing after a reboot | A member dropped, or the file system damaged | Imaged; assembled; repaired on the image |
| No manufacturer software any more | The brand has gone | Not needed; the layers are standard Linux |
| Drives read as unformatted in a PC | ext3, ext4 or XFS on mdadm | Mounted from the images |

Work we have closed →Logged the day it lands, and the first look costs nothing Free
A case number goes on the parcel and a number on every drive the day it is opened, and an engineer settles what has actually happened before anything spins. The unit is examined on its own; each drive is assessed on our own equipment, never in a NAS that will try to rebuild. Back to you come two things together: a straight note of what is liftable and what is not, plus one figure, fixed and written down. Accept it, or decline and owe us nothing.
The unit, and the drives, apart
The box and the disks are two different jobs. The unit is tested separately, because a dead power supply, a failed board or a bricked boot flash leaves the drives untouched more often than not. Each drive is then read on the bench: the ones that answer at full speed, and the weak or failed ones in clean air where they need head work. On units that hold an encryption key or a layout of their own, the unit is part of the data and is kept with it.
Every member imaged, once
Nothing is worked on live and nothing is rebuilt on the originals. Every drive in the set is imaged sector by sector, the weak ones head by head with the bad areas last, and the SSD cache with them where there is one. From then on the originals are not touched again.
The set put back together, from the images
Order, chunk size, parity rotation and the reshape point are read from the drives' own metadata and the array is reassembled in software: mdadm and LVM under SHR, X-RAID and QTS pools; a ZFS pool imported read-only; Drobo's BeyondRAID zones reconstructed. The file system, Btrfs, ext4, XFS or ZFS, is repaired on the virtual volume, and encrypted volumes are unlocked there with the key you supply. Never on the originals.
You see the file list before you pay
What was recovered is listed for you first, and only then does a bill exist. Approve the list and it is invoiced; turn it down and it is not — and where nothing has come back, most jobs carry no charge at all. Recovered data travels home on fresh media bought in for your job, with the postage at our end. Your case is not closed until you have opened the files on a machine of your own.
From the bench
- The brand has gone; the layout has not. These units are mdadm and an ext or XFS file system, read from images without the maker.
- Years off is not years safe for the drives inside, which stick and seize like any others. Let the bench bring them up once.
- Do not buy a used unit of the same model to try the drives in. It offers to initialise them, and some do without asking.
What helps, and what harms.
Do this much first
- Power down and label the bays
- Send every drive and the unit
- Tell us the model and what it last did
- Say what you hope is on it
What sets us back
- Trying the drives in another unit
- Initialising drives a PC shows as unformatted
- Powering it repeatedly to see
- Opening the drives
Questions answered before you commit.
Cisco no longer lists my NSS322. Can it be recovered?
Yes, from images, without Cisco.
Can a PC read the drives from my Cisco / Linksys?
No. They carry a Linux volume, usually over mdadm, and a PC offers to initialise them. They are mounted from images on the bench.
What does it cost?
£300 + VAT for a single-drive unit; any set is £500 + VAT upwards, fixed in writing after the free look.
How long does it take?
5–10 days at the bench for a set; 3–4 days at the bench for a single drive.

Nothing gets worse while it is powered down.
Looking at it is free. Back comes a list of what opened and what did not, together with a single price to finish, set down in writing while you are still free to say no. On most jobs an invoice only follows the data. Until that list reaches you, leave the unit off and the drives in their bays.
