Diskmod is a filter driver made by karyonix long time ago (First version is from October, 2009), in no way I'm trying to take any credit on the development of this fantastic filter driver, the pourpose of loading it to this repository is to keep it easy available to download, and as a tribute to the developer, karyonix Topic name is not very intuitive if you are not looking for: Page file in USB hard disk, by the way I used it first time on my very first Win7 VHD on a USB HDD, long time ago as on those times Ram usually available on PCs was very limited and it was necessary to have a Page file on the USB device and avoid to create it on the internal HD and make the VHD fully portable.

This is original topic from karyonix http://reboot.pro/to...isk/?hl=diskmod

And you may find on author topic a download link for v0.0.2.2 and additional info on this post: http://reboot.pro/to...isk/#entry86619

It is not required anymore on Win10 since from v1703 this OS is capable to read/write to multipartitioned USB sticks.
But it is very usefull on previous OS as Win7 and Win8.x to let this OSs have access to multipartitioned USB sticks.

Diskmod.sys was originally written to allow pagefile.sys to reside in a USB Hard Disk. However its other features include disguising UFDs as HDDs and HDDs as UFDs.

This driver is not signed so to install and use it you have to activate Test Mode (testsigning) before installing it.

Install and use diskmod.sys (when running the .bat files do it as admin, just in case)
1.Download and extract diskmod.zip
2.Right Click on diskmod.inf – Install
3.Run UFDasHDD.bat and replug your USB Flash Drive to make it appear as Fixed Disk
4.Run UFDNormal.bat and replug your USB Flash Drive to make it appear normally as Removable Media
5.Run USBHDDasUFD.bat and replug your USB Hard Disk to make it appear as Removable Media
6.Run USBHDDnormal.bat and replug your USB Hard Disk to make it appear normally as Fixed Disk.

Features
USB Flash Drives can be disguised as USB HDDs
USB HDDs can be disguised as USB Flash Drives. This feature was missing in cfadisk.sys and dummydisk.sys
Easy to install. No Reboot required (even if a message asking for reboot appears).
Very easy to switch between Removable and Fixed modes for both USB Flash Drives and USB HDDs.You just have to change a value in the registry and replug your USB Device
All connected USB Devices are affected. Karyonix’s post at reboot.pro mentions that individual USB Devices can be targetted without affecting the other connected USB Devices. However this is a complex procedure, it is easier to just apply it for all USB devices using the batch files included in the download.
Diskmod is one of the best filter drivers available for disguising a UFD as a USB HDD or vice versa.

This filter driver is not required when using Win10 v1703 or newer on your VHD, VHDX or WinPE.

 

Using this filter driver on a VHD, a VHDX or a Wimboot VHD made from Win7, Win8 and Win8.1

 

This driver is very usefull if you want to boot a VHD, a VHDX or a Wimboot VHD located on a multipartitioned USB stick, SD or MicroSD, and you want to have read/write access to all its partitions, I have been using it for long time for this pourpose, just forgot to mention it, since I tought everybody was aware of this.

 

Using this filter driver on a WinPE made from Win7, Win8 and Win8.1

 

For instructions to permanently install it on your old already made WinPE, see this topic: http://reboot.pro/to...-sd-or-microsd/

 

For temporary use on your WinPE see second post on same topic, and also an alternative solution with some comments of the disadvantajes of it.

 

EDIT: To include diskmod in new builds made from 7 or 8.x sources, Please see Diskmod.script: http://reboot.pro/fi...-diskmodscript/

I have used this for some years, however my SD card is rock steady before I install the diskmod driver but dismounts / disappears / hangs reasonably frequently when it is installed.

 

Any ideas anyone?

It is only required on Win7 to Win8.x, but it is unnecesary on Win10 v1703 and newer.

 

On first and second posts you can find all instuctions to use it.

 

I have it installed on my Win7 and Win8.1 WinPEs and also on Win8.1 VHDs and all of them boot very fine from several MicroSDs + a USB 3.0 adapter on 5 different PCs at home, and I can have access to all partitions on my MicroSD cards, so this filter driver works very fine..

 

Since you said you have used it for some years, it is possible you have an old version, I suggest you to install this version and try it using another spare USB device, if it works fine this way, and you still have issues on the problematic SD, it may be something wrong with that SD card, then maybe it is a good idea try repartition it as MBR, don't use fast formart, this way the slow format will verify there is not any bad block/sector on the failing SD (and will mark and isolate it/them if present).

 

I wish you good luck on your tests.
