Hi.

 

For unattended Windows Installation in PCs containing both SSD and HDD, It is required to detect SSD Drive Number. I have tried wmic in boot.wim environment to get any info regarding SSD. But unable to find out a way to figure out which Disk is SSD or HDD. 

 

Is there any method to detect SSD Disk Number in WinPE environment using CMD batch file ?

 

Please help...

Find the smallest "Fixed hard disk media" device?

Not accurate/universal of course, but I would guess that it would be accurate on 99% of PC's with one SSD and one HDD.

 

Also, "unattended" requires anyway some initial attendance, unless - maybe - if it is "mass deploying on n identical machines" (in which case the target device can be set to a "fixed" value or "Model" can be used to find the SSD with WMIC)

Is there any 32-bit winpe and 64-bit winpe simple command line program to measure random-reads of an unformatted disk and output result to console ?

 

This way we will be abole to list SSD and HDD as per these speed in decending order for preferred instalation disk !

Well, you can use dsfo with output to nul and read the time it took in batch.

Something *like*:

dsfo \\.\Physicaldrive1 0 1073741824 NUL

will result in something *like*:

OK, 1073741824 bytes, 39.510s, MD5 = 786a48c5db7548a6bf34cb945b62ae75

but of course you need to add dsfo to the winpe build.

 

These are not random, but rather sequential reads, but the speed difference between a SSD and a HDD should be noticeable nonetheless.

nwinfo.exe seems interesting now. It may help...

[Wonko the Sane]

It depends on how (exactly) that information is retrieved.

 

Powershell has a suitable command but it is said to be not always reliable

Get-PhysicalDisk | Format-Table -AutoSize

It runs under WinPE OK.
