If your WD MyCloud device no longer shows the hard drive or shares in the Web GUI, but your PC can still access the files, this usually means the MyCloud’s core services are running, but the Web UI or indexing services are partially broken. This is a common MyCloud failure mode and often recoverable.What this situation meansBecause your PC can still see the shares:The Linux OS is runningThe disk is mountedSamba/SMB file sharing worksHowever, the Web GUI depends on:Database servicesIndexing (wdmcserverd)Web server processesIf any of these fail, the GUI may show “No drive detected”, no shares, or appear empty.Common causesCorrupted MyCloud database or config filesOften caused by power loss or improper shutdownFirmware update failureUpdate completes partially, breaking the GUIFull system partitionLogs fill /var, preventing services from startingIndexing service crashDrive exists but GUI can’t “see” itStep-by-step things to try (safe first)1. Power cycle correctlyShut down MyCloud from the Web GUI if possibleIf not, power offUnplug power and EthernetWait 5 minutesReconnect Ethernet, then powerThis clears stuck services.2. Try a different browserUse Chrome or FirefoxTry Incognito/Private modeClear cacheThe GUI can break due to cached JavaScript.Advanced but common fix (SSH required)If you’re comfortable with basic commands:Enable SSH (if possible from GUI)Connect:ssh root@MyCloud_IPRestart core services:service wdmcserverd restartservice apache2 restartservice avahi-daemon restartMany users report the GUI immediately comes back after restarting wdmcserverd.If the drive shows “missing” in GUI onlyThis strongly suggests database corruption, not disk failure.You can rebuild the database:rm -rf /var/lib/wdmcserver/rebootThis does not delete your data, only the media index.Important: check drive healthEven if files are accessible, back up your data now.MyCloud devices are notorious for:Aging power suppliesSilent filesystem corruptionSudden total failureIf the GUI problem keeps returning, the drive may be degrading.When firmware reinstallation helpsIf nothing restores the GUI:Download the exact firmware version for your modelPerform a manual firmware installAvoid auto-update if your data is criticalWhen to stop troubleshootingIf:Web GUI never shows the driveReboots no longer helpServices won’t restartThen the device is in pre-failure state. At that point, treat it as a network drive only, copy data off, and plan replacement.If you want, tell me:Exact MyCloud modelFirmware versionWhat the GUI shows (exact message)I can give you model-specific commands or recovery steps.

MyCloud now cannot see harddrive or shares via WebGui, PC can!

Here’s a clear, updated look at whether the WD My Cloud PR4100 network-attached storage (NAS) device is discontinued — including what that means for buying one, support status, and practical consequences.Current Availability and Sales StatusThe PR4100 is noticeably hard to find new through official retailers and distributors. Many regional sellers list models as out of stock or unavailable, and some older SKU listings show the product as no longer available.In community discussions, users have observed that it’s becoming very difficult to locate new units through WD’s own store or authorized retailers, prompting speculation that WD may be phasing out production or availability even if no formal announcement exists.Bottom line: The PR4100 appears unavailable (or nearly so) in many markets, but there’s no official WD statement confirming a formal product discontinuation in the sense of “end of life” like you’d see in enterprise equipment. It may simply be out of production and sold out.What “Discontinued” Could MeanThere are a few different aspects to consider:1. Retail AvailabilityIf most retailers no longer list it, that practically means it’s out of regular sale. Many NAS buyers now report the PR4100 is not stocked or redirecting buyers to other products — a typical sign that a model is at or near the end of its sales cycle.2. Software & Support LifecycleEven if the hardware is hard to buy, WD’s support lifecycle policy shows that the PR4100 is still within its support period under My Cloud OS 5:Western Digital’s Product Lifecycle Support Policy lists the PR4100 with a planned support timeline extending through December 2026 for software updates and security patches.That means WD hasn’t declared it fully “end of support” or “obsolete” yet — as long as OS5 is supported, the device can receive firmware/security updates.However, WD has already ended support for older software (OS3), and remote or cloud access is limited for any device not updated to the latest firmware.3. No Major Successors or ReplacementsUnlike some product lines, Western Digital hasn’t widely promoted a direct successor to the PR4100. Many users in forums note a lack of new NAS offerings from WD, especially at that prosumer level, which fuels questions about WD’s direction in NAS hardware.Practical Implications for Owners or BuyersIf you already own a PR4100:You can continue to use it normally.Firmware updates and security patches via My Cloud OS 5 should continue until at least end of 2026.Past that point, support could cease — meaning no more updates, and cloud services or remote access might stop.If you’re considering buying one:New units are hard to find. You’ll likely be looking at used or leftover stock rather than fresh inventory.Since WD hasn’t clearly announced a replacement, alternatives from brands like Synology DiskStation DS425+ NAS or TERRAMASTER F4‑212 4 Bay NAS might be worth considering depending on your needs.SummaryOfficial discontinuation? — Not formally announced by Western Digital.Retail availability? — Very limited or absent in many markets.Software support? — Still in support through at least 2026 under WD’s lifecycle policy.Practical reality? — Effectively, the PR4100 is out of production / hard to find, but it isn’t officially “end-of-life” yet in the technical support sense.If you want, I can also help compare current NAS alternatives with similar performance to the PR4100 — let me know your budget and what features matter most!
