WD My Cloud RAID 5 Data Recovery: 18TB Rebuilt for an Overseas Client

An Overseas NAS Failure That Standard Tools Could Not Read

Alexis runs operations from Papua New Guinea, and when a NAS holding roughly 20TB suddenly showed only a handful of accessible files, the backups that mattered most looked gone. The three Seagate 8TB drives went into a box and travelled to the Sydney lab, which is how this WD My Cloud RAID 5 data recovery case began. Alexis had already tried recovering the data with UFS Explorer at home and got nowhere, which is a common starting point for the NAS cases that reach us from overseas.

Tim at the Sydney office ran the first round of testing. None of the three drives had a hardware fault. That ruled out the usual mechanical suspects and pointed at a file system problem, so the job moved to Payam Toloo to solve.

The Problem: 20TB of Files That Would Not Show Up

Payam connected all three Seagate drives and checked how Windows saw them, then ran WinHex to compare the contents side by side. Each drive sat about 90% full of unique data. That pattern told him straight away he was looking at a RAID set, and almost certainly RAID 5. He opened UFS Explorer and a WD My Cloud NAS volume appeared. He searched for the Veeam backups by their .vbk file extension and found none. The same tool flagged something else worth chasing. A fourth drive should have been part of the set, and it was not in the box.

Payam called Alexis, who confirmed there was indeed a fourth drive and sent it across. Two days later it arrived, and it was a surprise: a red and white Western Digital drive, while the original three were all Seagate. He plugged it in to compare, and the result was the same. He also quietly checked for any sign the NAS had been hit by a hack or ransomware, something he sees more often than most people expect. Not this time.

The WD My Cloud RAID 5 Data Recovery Process

Payam copied the RAID settings into File Scavenger, but it could not read the partition at all. There is a clear reason for that. A WD My Cloud unit runs on a Linux EXT file system, the same base many NAS units use, but it handles file storage in an unusual way. Instead of saving files under their real names and folders, it stores everything under system-generated codes and keeps the real names in a separate index database. Strip away that database and ordinary recovery software just sees a wall of meaningless codes. That is exactly why Alexis’s own UFS Explorer attempt had failed before the drives ever reached Sydney.

So Payam did it by hand. He browsed the reconstructed volume folder by folder, hunting for the tell-tale signs of where real user data lives: shortcuts, log files, and large folders packed with subfolders. Then he ran the numbers. The set held around 18TB of actual files, very close to the amount Alexis said was missing. The data was all there. It simply was not sitting where the client expected. For a deeper background on how striped and parity arrays store data, the Wikipedia entry on RAID is a solid primer.

The missing Veeam backups were not the real story. The files Alexis needed were intact and living in two large shared network folders rather than as .vbk archives. Payam opened a few documents to confirm they actually worked, then began saving everything to a new 26TB drive. Alexis will get a full file listing and a video preview of the recovered data. Once that is approved and the invoice is paid, both the original drives and the recovery drive ship back to Papua New Guinea by FedEx, with a secure backup held in the lab until the client confirms they are completely happy. In the end, Alexis got back everything they came for.

Why Professional WD My Cloud RAID 5 Data Recovery Matters

A failing NAS is one of the easiest places to turn a recoverable situation into a permanent loss. Running consumer software against a live array, forcing a rebuild, or swapping drives in the wrong order can scramble the parity that holds the data together. The WD My Cloud index quirk makes it worse, because the data can look completely gone to a tool that cannot read the index, which tempts people into reformatting or starting over. Understanding how a network-attached storage device lays out a file system is the difference between reading the array correctly and overwriting it. This is the kind of job where manual analysis beats any automated button, and where the safest move after files disappear is to power the unit down and leave it alone. If you are weighing up your options, our RAID and NAS recovery team can assess the situation before anything risky happens.

NAS and RAID Data Recovery Pricing and Services

Every RAID and NAS case starts with a free assessment and a written quote, and no chargeable work begins until you have agreed to it in writing. You stay in control of the decision. For NAS and RAID recoveries, economy work generally falls between $800 and $10,000 depending on the number of drives, the array type, and how much manual reconstruction the file system needs. Larger enterprise arrays and multi-drive failures can run higher, which is why the written quote always reflects the specific job in front of us rather than a guess. Some cases that involve a physically failed drive carry a $500 attempt fee, and that fee forms part of the total rather than being added on top of it. This particular job had no hardware fault, so it was handled as a logical and file system recovery. You can request a free data recovery quote for any brand of NAS or RAID, local or international.

Frequently Asked Questions

Why did only a few files show up on my WD My Cloud NAS?
A WD My Cloud stores your files under system-generated codes and keeps the real file names in a separate index database. If that index is damaged or unreadable, the volume can appear nearly empty even though the data is still on the drives. The files are usually still there, just not visible to software that cannot read the index.

Can data be recovered if one drive from the RAID set is missing?
Often yes, depending on the RAID level. A RAID 5 set can survive the loss of one drive, but recovery is far more reliable when the full set is present. In Alexis’s case, the fourth drive turned out to be a different brand, and having it on the bench helped confirm the array and complete the WD My Cloud RAID 5 data recovery.

Why couldn’t UFS Explorer or File Scavenger read my WD My Cloud drives?
Those tools are excellent, but the WD My Cloud index database can stop them from mapping codes back to real file names and folders. Without that mapping, the software sees meaningless codes. Recovering the data then comes down to manual analysis of the reconstructed volume, which is what we did here.

Were the Veeam backups actually lost?
The .vbk Veeam backup files were not where the client expected them, but the underlying data was intact. It was stored in two large shared network folders rather than as Veeam archives, so once the array was read correctly the files were all recoverable.

Do you accept NAS and RAID cases from outside Australia?
Yes. We regularly take on international work, including this case from Papua New Guinea. Drives can be shipped to our Sydney lab, and recovered data plus the original drives are returned by courier once the job is approved and paid.

How much does WD My Cloud RAID 5 data recovery cost in Australia?
NAS and RAID recoveries generally start in the $800 to $10,000 range for economy work, with larger or more complex arrays costing more. Every case begins with a free assessment and a written quote, so you know the figure before any chargeable work starts.

How long does NAS recovery take?
It depends on the array, the number of drives, and how much manual reconstruction the file system needs. A clean logical recovery moves faster than a multi-drive case that requires hand analysis. We give a realistic timeframe with the written quote.

Is it safe to keep using my NAS after files disappear?
No. Continuing to use a NAS after files vanish risks overwriting the very data you want back, and forcing a rebuild can scramble the array. The safest step is to power it down and get it assessed before anything else is done.

Video Transcript

Hi, it’s Mike. Today I’m in Sydney, Australia at the lab of Payam Data Recovery with the owner, Payam Toloo, watching a real case come together. A customer named Alexis all the way from Papua New Guinea sent in three Seagate 8TB drives from a NAS. They had around 20TB of files, but suddenly only a few were showing up. What they really wanted back were their Veeam backup files. The drives were tested first by Tim at the Sydney office. No hardware faults at all, so that pointed to a file system corruption and the job came to Payam to solve.

Payam connected all three drives, checked how Windows saw them, and then used WinHex to compare them. Each drive was about 90% full of unique data, which told him straight away this was a RAID set, most likely RAID 5. Payam opened UFS Explorer and a WD My Cloud NAS volume appeared. He browsed for the Veeam backups and searched the .vbk file extension, but found nothing. UFS Explorer also hinted there should be a fourth drive, so Payam called Alexis and asked for it. Two days later it arrived, and interestingly, it was a completely different drive, a red and white WD, while the original three were all Seagate.

Payam plugged it in to compare, but the result was exactly the same. He also quietly checked for any signs the NAS had been hacked or encrypted for ransom, which he sees more often than people expect. Thankfully, not this time. Payam copied the RAID settings into File Scavenger, but it could not read the partition at all. Here’s why. A WD My Cloud runs on a Linux EXT file system, the same base many NAS units use, but it does something unusual. Instead of saving your files under their real names and folders, it stores everything under random system-generated codes and keeps the real names in a separate index database. Without that database, ordinary recovery tools just see meaningless codes, which is also why the customer’s own UFS Explorer attempt had failed.

So Payam started browsing manually, going through the folders and files by hand, looking for clues like shortcuts, log files, and any large folders with lots of subfolders to work out where the real user data was actually stored. Then he did the maths. The drives showed around 18TB of real files, close to what was missing. The data was all there. It was just not saved as Veeam backups. It was sitting in two large shared network folders. Payam opened a few documents to confirm they worked, then started saving everything to a new 26TB drive.

Alexis will get a full file listing and a video preview, and once it’s approved and paid, both drives ship back to Papua New Guinea by FedEx with a secure backup kept here until they are happy. In the end, Alexis got everything back they wanted. Payam and his team have been recovering RAID and NAS units since 1998 using specialised hardware, software, and AI tools. But as Payam tells me, sometimes it just comes down to old-fashioned troubleshooting to work out what the customer actually needs.
