Slowing down fast / modern (one you can buy in the shops - today - not second hand) CD/DVD drives
The drive I am using is a 22x Samsung IDE DVD Writer: http://www.samsung.com/ae/consumer/computers- … type=prd_detail
It's very fast, which is great for installing software, but there are 2 issues:
- The drive is noisy
- Worse is the spin-up / spind-own pauses
If you move around folders the drive constantly spins-up and down and the machine waits for the drive to start reading.
Back in the old days up to 4x I believe (or was it 8x?) drives wouldn't spin-down. They just span at a constant speed all the time and access was ASAP. No delay whatsoever.
So I was looking for a solution to this problem. I remember that I had a TEAC CD drive as a kid, which you could tell to slow down. So I was hoping this wold still work with todays drives, and guess what! It did 👍
This is the current state of my time machine:
This is the Samsung 22x IDE DVD Writer:
I use a Windows 98SE boot disk, because they come with CD drivers and should work with any drive.
The config.sys line for the drive looks like this (I did change the drive name to Mau1wurf)
And the boot screen looks like this:
Drive works fine, but you get the spin-up and spin-down delays and the drive gets a bit noisy (not very loud though...)
Now in order to slow the drive down, we need to get the TEAC CD driver. Well good on TEAC, they still host this driver!
You can grab it here: http://www.teac.com/DSPD/downloads/drivers/atapicd.exe
It will extract 2 files, the driver and documentation. However the slowdown option isn't covered in this document...
For this example I copied the driver (TEAC_CDI.SYS) on the Windows 98SE bootdisk. Obviously you can copy it onto your HDD and change the following line accordingly.
Next you either replace the line in config.sys I quoted above with the new TEAC driver (instead of the OAK one)
DEVICE=A:\TEAC_CDI.SYS /D:Mau1wurf /S:4
The /S:4 tells the drive to spin at 4x speed (I did a DOS test and it reported 8x speed so I am not sure what speed is correct, however the issue was adressed)
You get this boot screen, with confirmation that the /S:4 command worked:
From here on my drive was fast and ready from the get go. No spin-up and spin-down! No noisy drive as well.
Job well done!
