Question: I’m getting errors in Windows 10’s event log stating DeviceHarddisk1DR2 drive controller is having a problem. I know that the hard disk numbers depend on the BIOS and do not match the physical connections.
How can I tell which physical device this actually is? diskpart lists these devices:
?Disk ### ?Status ?Size ?Free ?Dyn ?Gpt ?——– ?————- ?——- ?——- ?— ?— ?Disk 0 ?Online ?931 GB ?0 B ?* ?Disk 1 ?Online ?1863 GB ?927 GB
Is DeviceHarddisk1 the “Disk 1” listed here? Is there some other way to determine what Windows 10 means by Harddisk1 ?
What is DR2?
Answer:
How can I tell which physical device this actually is?
You can use wmic diskdrive get caption, deviceid, size to match up the devices shown with physical disks.
Example output from my laptop:
DISKPART> list disk ?Disk ### ?Status ?Size ?Free ?Dyn ?Gpt ?——– ?————- ?——- ?——- ?— ?— ?Disk 0 ?Online ?465 GB ?0 B ?Disk 1 ?Online ?59 GB ?0 B ?Disk 2 ?Online ?2794 GB ?7168 KB
And:
F:test>wmic diskdrive get caption, deviceid, sizeCaption ??DeviceID ?SizeWDC WD5000LPVX-08V0TT5 ?\.PHYSICALDRIVE0 ?500105249280SanDisk Cruzer USB Device ?\.PHYSICALDRIVE1 ?64009128960Seagate Expansion Desk USB Device ?\.PHYSICALDRIVE2 ?3000582144000
As you can see from the deviceid, and confirmed by the sizes, the devices are listed in the same order on my Laptop.
Note:
- The OP has stated that the wmic on his PC lists the devices in the reverse order. The information still allows the disks to be identified.
