In Windows 10, you can see aserial number for the hard disk installed in your PC using the command line. If you need to print it out or just view your hard drive details without restarting your PC or using a third party tool, it can be done with a single command.RECOMMENDED:A serial number is a unique number assigned to the hardware by its manufacturer. It is used for identification and inventory purposes. A serial number allows the manufacturer to identify a product and get additional information about it. It may be required for replacement, updating firmware, or for checking compatibility with other hardware.Usually, the serial number is labeled on the drive's case.However, it is required that you disassemble your PC to see it.
Here is how to see it with built-in Windows 10 tools.To find Hard Disk Serial Number in Windows 10, do the following. Open an. Type or copy-paste the following command: wmic diskdrive get Name, Manufacturer, Model, InterfaceType, MediaType, SerialNumber. In the output, you'll see the model, name, and serial number listed for the installed hard drives.The command above will give you information about the storage devices you have.
I was just working on this and I thought I would share it with everyone.One customer asked about getting the serial numbers of USB Storage Devices. Hey everyone,I'm trying to allow only certain serial numbers be able to use usb storage. Since not all USB Mass Storage device have hard coded serial numbers, they all do have hard coded and unique deivce IDs. This device ID also matches with the registry key name.
In Win32Volume there is the welcome DriveLetter (C:) as well as SerialNumber which is an integer 681259522, for example).In Win32DiskDrive there is also a SerialNumber, but now it is a string. Typically, it has leading hex 20s followed by other characters - here the same drive as above has Is there a way to transform one of these Serial Numbers so as to be able in a script to get the DiskDrive information (maker, model, interface.) for a particular drive letter?a79 years old. This doesn't really doesn't address the underlying issue shown in the question: WMI is returning acorrupt serial number. Mark is getting the serial number encoded as hexadecimal digit pairs which represent theASCII characters of the actual serial number. This does not match the documented behavior.This is a long-standing bug in WMI which Microsoft has yet to address, or even explain. There has never been a clear answer as to the root cause of this bug, only statements that Microsoft won't address it because it ostensibly involves unspecifiednon-Microsoft software.Another symptom is to intermittently get the correct serial number, but with pairs of characters flipped. You can also get different results based on your UAC settings.

Free ocr software download. The serial number has been inserted as a hex string. Thisis also the way SNMP serial numvers are meant to work. WMI and CIM make no attempt to convertthis data.
That is up to the end user. YOu must know how the vendor inserts this.Yes - with some sensitive items like serial number fields you must run elevatd to see them This a security consideration and not a bug. It is an intended behavior.We are moving now to CIM standards. We should see, if nothing else, better documentation on how these fields are intended to be set up and used.Al littel further testing and studying how WMI is deployed and used historically might help you to weed you way through this. Note that earlier versions of WMI did not even have a disk serial number.The device serial numvbers as Boe has pointed out above ar just vendor strings. If you don't like the contents then complain to the vendor. To prove this just view the property in WBEMTEST.

Windows WMI does not ever convert or interpretany values in WMI.This si a very commong mistake for may who are not engineers or who have only basic asmin training. WMI is an engineering tool. It is designed and specified at an engineering level. It is similar to SNMP but includes OS and confighurationitems not monitored or manged by SNMP.Those that are not trained in these technical tools frequently assume that the behavior that they see is somehow a Windows deficiency when, in most cases, it is intended to be what is seen in use, or, the behavior and usage of item is not understood.There is much to criticize in WMI but this is not one of those items.

As I mentioned above, this is being addressed in WMF 3.0 and beyond. Once the specs ae complete then the vendors will have to comply.
This can take a few years;usually less than two.Her eis the Win32DiskDrive SerialNumber property dicription: Its source and usage are very clear. It is a manufacturer supplied string. SerialNumber Data type: string Access type: Read-onlyNumber allocated by the manufacturer to identify the physical media.Example: WD-WM. To the moderator: my apologies, I wasn't attempting to post a bug here we're already working on that with Microsoft Support.
Like the original poster, I've been looking for work-arounds to these issues. I get a little frustrated whenI see folks ask questions that I would like to see addressed, and then an answer which I feel misses the point of the question gets marked as an answer by a Microsoft employee instead of by the person asking the question.
That just seems like a way toscare people away from the forums. Sorry that my tone was so harsh.jrv,Thanks, your reply is actually very helpful. I think the key part of my post you may have missed was where I mention theintermittent results we see. Same vendor, same drive, but the serial number comes back in different forms for thesame WMI property. That is what has led us to conclude that WMI isn't merely passing that data back as-is we would actually prefer that. We're just not sure if it's attempting to fix the values butafter a delay, or if it's switching which driver calls it uses, or if there are just race conditions inherent in the design of the system.Do you have any theories that could explain that sort of behavior?
Are you proposing that the 'vendor' not sure if you mean disk manufacturer or motherboard driver vendor is changing the format on the fly?At this point we'd be happy to abandon WMI and go straight to the device drivers yes, I'm an experienced engineer, and I've studied the CIM, SCSI, etc. Standards, and we even design and manufacture our own motherboards here, but now we're in a positionthat we have to reverse-engineer whatever WMI is doing and try to emulate that for backward-compatibility, but more reliably. Since I raised several different issues, let me tackle them one at a time since I think they are distinct and some might be off-topic for this particular thread. Also, since this is a Scripting forum, I'll just use PowerShell examples our shippedcode had to embed these queries in an application, so we go straight to the underlying.NET calls there - not sure if it's against the rules to post C# code here.Anyway, for now let's just talk about the prevalence of hexadecimal format, and the predictable non-intermittent format changes I've seen. Here's a simple query run on my Windows 7 system. The blue window is running as an elevated account,the black window is running as a normal user account. Note that none of the drive serial numbers are in hexadecimal.
Also note that the query returns the values in different forms big-endian or little-endian ASCII depending on which user doesthe query. To make things more unpredictable, the third drive's serial number remains the same it's a CD drive, so we can't make reliable assumptions about how to 'fix' the serial numbers. This particular behavior is all new with Vista; our codehad worked as expected on Windows XP.In our experience, the hexadecimal form that the original poster mentioned is a rarity. But most of our drives are Seagate or Western Digital, so maybe those are a rarity in the marketplace.So based on your assertion that all of these drives are likely returning their IDs in hexadecimal, doesn't that imply that WMI or something else is doing some additional processing of the values to get the results shown below? Also, note that Microsoft'sofficial documentation for this property after the screen shots show an example that is non-hexadecimal. So, based on the documentation, I wouldn't criticize the original poster for being surprised at getting a hexadecimal result, since the documentationsets a possibly inappropriate expectation that the value returned will match what is printed on the drive's sticker.Microsoft WMI Documentation: SerialNumber Data type: string Access type: Read-onlyManufacturer-allocated number used to identify the physical media.Example: WD-WM.
I really fon't want to pursue this any further as it is not a scripting issue.The system is woking exactly as it should. If you switch betwween user sessions and use different environments on a neer server then the string may be read as Unicode. It is defeined in WMI as a WMI string. It is NOT defined as hex or asbinary.
It is just a string. The byte order will only cahnge if it is being read from a Unicode session. WIn32 and VBScritp and POwerSHell 2.0 all read strings in ANSI format. Under 64 bit and if users are configured for MUI supportthen the string can be misread. The string is stil stored exactly the same and under all accounts WBEMTEST will show you the same strings.What you are seeing is due to local differences in the session used to read WMI.
WMI and the hardware are not changing.It is quite easy to get fooled by all of this. It makes me crazy sometimes becuse I end up thinking similar things but have always found it was not WMI or WIndows. In most cases it is differences in the sessions that are used to do the testing.The strings are being read by the driver API. WMI calss a DLL that uese the driver API to request the vendor info.I suspect a good way to test this is for you to use PowerSHell 3.o and the CIM CMdLets as they have full support for Unicde and double byte environments.
Older programs may behave oddly if the culture is changed or if the environment is switched between32 and 64 bit.I have scanned all over a number of networks and have not been able to detect and instability in serial number reporting.Be careful in C#/VB and C becuse teh naticve string is Unicde but WMI is ANSI. Reaidn into a C# string in VS2008 or later will appear to reverse the byte order. If you sue CreateObject or its Net equivalent instaead of the Management classesyou will get even stranger results including numbers that are odd.In all cases I am familiar with the Net Management classes have correct support for accessing WMI classes.¯(ツ)/¯. That is exactly what you see wwhen the evironments are set differently. ONe is defaulting to 32 bit and the other to 64 bit.Run only the 32 bit environment in both session and it will be the same.You must explicitly launch the 32 bit session.I haev also tried thsi directly on WS2012 64 bit and I do not see any issue.I am not running the MUI version of Windows anywhere.The byte order is exactly what we would see dumping ANSI to a Unicode prompt.If I really though this was a scripting issue I would build a script that can force the situation with all strins in a file.YOu have alreaady proven that the difference is between accounts.
Now figure out why the accounts are different. It can only be the environment. Tere is nothingmagic about the way WMI returns a string. Ther eis a differenc in theway strings are managed in different Unicode environments. We have 'bigf indians' and littel indians' and 'ANSI non-indians'. Lots of ways to mess up.¯(ツ)/¯.
