I logged on to my PC today and found that all the disks that are connected via sata 3 cables to my motherboard are now unallocated. This includes one 1TB 850 Evo and two 2TB WD Blues. I did not get any Windows updates last night, as far as I can see. I have tried putting the drives in another PC, and they show as unallocated. I am unsure what could have possibly caused this, and very scared that all the stuff stored on these drives may be lost. I have run the Seagate bootable tool and found my drives are fine. The drives had no issues being detected by Windows or in BIOS. I am aware there are 3rd party recovery tools, and would love suggestions on ones people have had real success with; although I would prefer to stay away from 3rd party apps if I can fix it without them. Does anyone have some suggestions?

https://www.wavlink.com/en_us/product/WL-ST336A_Black.html My wavlink HDD dock made 2 of my backup hdd corrupted or inaccessible for almost 4 times already since January. The Seagate 3 times, WD 1 time. It's done it so many times that I've given up on the files on the Seagate drive, and used it as a test sample on what makes the hdd dock do this to my drives. So far nothing made sense and it just does it whenever it wants to, I think the dock is now faulty. I tried fixing/recovering the drive with cmd but after fixing the drives, the files dont show when exploring I tried using SeaTools to check if theres something with my drive. it passed everything 100% but the advance testing made it undetectable in Seatools and disk management. because of all this bullshit I accidentally tested another drive that contains all my important files. This hitachi drive became not initialized, now it asks me to make it GPT or MBR. It's status in disk manager is Unallocated. i haven't formatted it yet. Im planning to buy a data recovery software. Any recommendations on what to do? 1. Seagate = not detected 2. Hitachi & WD = unallocated all of this drives are 100% healthy

hi guys , i have 2 hdd one of them is wd purple 2tb and other one is wd blue 2tb. about 2 months ago both of my hard drives became unallocated suddenly without any reason , i recovered my files and initialaized the hard again . both of them were working fine until yesterday which this time one of them became unallocated . i dont know what to do now, i think it might be a psu issue ( it has some annoying coilwhine even when the pc is not turned on ) . asus tuf x570(wifi) 970 evo ssd (my os ) psu is cooler master master watt 650w gold. (non-modular)

Hi guys, Hope you guys can help me out, so I've got a 5tb WD Elements External Drive that was plugged into my pc, however I've changed my setup around and put my desktop under my desk, I've re-cabled everything back up and now the external drive is showing as unallocated, I have quite a bit of data on this drive so do not want to format it, is there any kind of fix for this. In Disk Management it shows as unallocated and only allows to create a new simple volume. Anyones help is much appreciated Thanks

Hey i clones my 1tb hdd to my new 3tb hdd and it wont boot, it just skips to my ssd or my 1tb hdd when booting up. And i have 746gb of unallocated space i cant merge with the rest of the 3tb hdd's memory. And most of the videos i watch are old and have same or similar softwate but is out of date and has a different layout so i cant just mimic their actions. If anyone has a gooood recently made video link for a fix to this it would be greatly appreciated. Ive been working on this off and on for like 4 days now. Heres a pic of the unallocated space with no options to do anything except go to properties. Also im using disk manager and EaseUS ToDo Backup free 10.0.

Here is a screenshot of Disk Management, Task Manager, and Partition Find and Mount. As you can see, my 2TB hard drive got fucked pretty hard. There are mostly unallocated partitions and two raw partitions at the end, the second of which has the correct partition size but lost its NTFS (and thus becoming RAW) and drive letter. Everything else should add up to one 1,939.45 GiB partition, but for the most part it became split unallocated partitions with one 10 MiB RAW partition in the middle for no apparent reason. So now time for the question of the day. How do I unfuck my partitions? You may be wondering how it happened and why I don't have backups. Well, I put my computer to sleep when I am not using it, like when I'm sleeping or at school. While I was at school, there was apparently an outage at home. I noticed my computer was turned off when I came back home from school, and I wasn't too concerned about it. I turn it on and notice that my D: (1939 GiB) and E: (apparently 14 GiB) drives are gone. Device manager still shows the drives are being detected, but not read from or written to, 0% activity. I check Disk Manager and saw what I see in the screenshot and I died a little on the inside. As for why I don't have backups, that is because I only have one 2TB hard drive and it is literally the biggest drive in the house by a landslide. Which explains why I have a 320 GB hard drive as my boot disk. Yes, boot times are abysmal, and I contemplate on suicide every time I wait for the damn thing to load. I swear I am going straight to NVMe SSDs when I get some dough, but I digress. I don't have backups because I never saw the need to and I never got around to buying another 2TB hard drive. I did ask my parents to buy me a 1000VA UPS with AVR, since brownouts are becoming noticeably more common, but they didn't listen and their excuse is "power outages don't even happen once a year." There were at least 5 outages this year alone, so I told them to blow it out their ass. Instead of asking my parents for shit, I am going to spend my own money that I have saved up over the years on some safety equipment, namely a UPS and an external hard drive, where I can back up my internal hard drive to and force myself into that habit. Quite a long story there, but I digress. I need my partitions back. Backing up to another drive then back is not an option as of now, due to aforementioned reasons. Edit: If it wasn't clear, or if you didn't read the fine print, backing up is not an option, since I don't have another drive big enough to back up to. All of the partitions except the last one form one whole partition where the majority of my data is stored, as seen in Partition Find and Mount. Since the partitions are split and became unallocated or RAW, I cannot access my data by conventional point and click means. I need to figure out how to crazy glue these partitions back together and do a little hocus pocus and hope it turns into NTFS the correct way.

Hello guys, I replaced my HDD with a new bigger HDD. I cloned the old one to the new and it worked. Only now I have 1,5TB unallocated space and in the Disk Manager I cant extend the volume of my C disk. How can I add this unallocated space to my C storage? Also I have a repair-partition that is 1,5TB while it only contains 500MB of data. Can I just remove this whole partition or do I have to make it smaller and why in the first place do I have such a partition? I included a printscreen of my Disk Manager. Thanks in advance for your replies!

Most of my SSD space is being unallocated and I don't know how to allocate them to the free space. Any advice would be great thanks

I have (Had) a Seagate FreeAgent Go 250gb portable hard drive, I have had this several years. Sadly one day I was an idiot and my assumptions that glass tables do not conduct electricity was painfully incorrect, so much so that I ended up hearing a crackle when I placed the hard drive on said table. What made it even more painful was the fact I realised I had not backed the data up on the portable hard drive, and on my main computer I had completed a format and moved the data - A decision I regret clearly! This incident happened years ago, and each year I come back to it hoping that advancements in software can one day reunite me with any data I may have lost, but each year I become disappointed as I get further away from trying to rectify this, the belief that the data may still be housed on the hard drive makes me want to continue trying... I have cracked open the housing contained within the Seagate which has left me with just the hard drive, so I have hooked it up to a SATA Dock which is externally powered. My BIOS can recognise the hard drive, and so does Windows 10 (All various versions did also). In Windows 10 Disk Management it shows as "Disk 3, Unknown 232gb Not Initialised" and the bar is "Unallocated". If I click on Initialize Disk it wants me to partition the drive using MBR or GPT. I have not accepted neither option because I don't want to risk losing the data on the hard drive permanently. I have tried various data recovery software as well as various scans without any success. Partition Magic, Partition Wizard, HD Tune, Data Recovery Pro - None have been successful in repairing this. HD Tune states that "(C5) Current Pending Sector" has a warning status attached, the scan indicates that this has 100% Damaged Blocks. Realistically I don't know what else I can do, software seems to be not helping at all, the only thing I can think of is to send it off to a Data Recovery Centre, but for about 10gb of saved data that doesn't seem worthwhile and costly to boot. I am keeping the hard drive setup for a few more days again, so if you want me to try anything I can certainly go for it and hope for the best.

I've noticed that Disk 3 and 4 never has anything connected to them but they always remain open in 'This PC' and 'Disk Management' does window just save these spots for certain things or something else? It bothers me every time I see them cause i don't know what is up with them. - Always shows up empty - Nothing ever gets assigned to be F: or H: when something gets plugged in - Why is it removable?

I got a new 3tb drive for some more storage for pictures and videos, but this 746.52 GB won't allow me to change the unallocated memory, so I only have about 2tb to use. Any tips? (yes, I'm watching a build guide in the background)

I recently opened up an external hard drive (a 3.5inch WD 3TB) to connect it internally with SATA. After installing it in my PC, it showed as an Unallocated drive, It seemed like there was an issue with the drive so I used a recovery software to recover all my data to another drive (Internal 3.5inch). After that I tried to format the 3Tb drive but the operation would fail. I wanted to backup the recovered data to another external drive to I connected a Seatage 2.5inch drive and copied all the recovered data. The operation seemed successful but after a while when I tried to access the drive even this one shows as "Unallocated". How can two completely unrelated HDDs have the same issue? Is this a Windows problem or should I check for a Virus? (I ran the windows defender scan and everything seems to be fine) Update: I connected the 3TB HDD to a Macbook and formatted to ExFat and it works just fine but when I connected it back into my PC it showed as Unallocated. So it initialized it and tried to create a new simple disk but got this error "The request could not be performed because of an I/O device error"

Why are there two unallocated pieces of my main drive (501 MB and 470 MB) and what is the the other 470 MB partition on my main drive labeled: healthy recovery partition, should i leave that one alone ?

Hi everyone! So I got a new SSD, and I used this program called "Clonezilla" to clone my old (120gb) SSD to my new (240gb) SSD. Basically, when I go to Disk Management, the new SSD seems to have 2 parts. Half is "Healthy (Primary Partition)" and the other is "Unallocated". Is this because I put 120gb worth of storage on a 240gb drive? If so, how can I fix this? Thanks in advance, any and all help is much appreciated

Hey guys. So I got this problem that disc manager doesn't recognize my new ssd drive, there is no "black" unallocated drive in the disc manager. But both BIOS and device manager recognize the new SSD. Samsung magician says that it "unable to detect SATA interface details" but it can detect my other SSD that is the exact same model... It's the Samsung 840 EVO 120 gb version.

Hello people, I have recently added a 3TB HDD to my PC as I need somewhere to back up my 1TB and to record my fraps videos too. I istalled the hard drive and I am a where that you need to allocate the HDD space but it only allows me to create new simple volume on 2TB of the HDD and the other partition of 768GB (or something like that) doesn't give me an option??! I have tried many things such as changing the size of the partitions, using different software, joining the partitions but nothing seems to let me use my other TB. Someone please help! Thanks
