How to reduce CD-ROM load speed

By DonaldA-M ·
I would like any suggestions of ways to reduce the amount of time between loading a CD and being able to read the contents. I have seen wide variations in the amount of time it takes, and hav seen no clear pattern to the cause. I know this has nothing to do the the read speed (36x, 48x) and I'm not sure even the seek time is a complete reflection of the variations.

A second issue is the best way to check the integrity of a CD - CD burning programs seem far from infallible in their integrity checks. I have found a freeware app that creates a checksum file of the items being burned, and then allows you to check that file against the CD, but I'm wondering about other options.

How to reduce CD-ROM load speed

Part 1:
Is DMA enabled for the drive?
Are there other IDE devices on the channel?
How much RAM, and free HDD space do you have?
These are a few of the items to check for speeding up CD access.

The files near the outside (end) of the CD read faster than the files at the center (beginning) of the CD on most drives. The 36X or 48X or 56X are for the end of the disk, and the rates are nearly 1/2 at the beginning of the disk.
With the possible exception of the Kenwood 72X that uses multiplelasers.

As to question 2;
I have seen a couple of freeware programs that run a file comparison between the source and copy disk after the cd is recorded.
What I do, is make 2 or more copies of any critical data.

Please note that the problem is machine independent - I can switch CD-ROM drives and the speed of access goes with the CD.

Also, the desire of the persons checking these CD's is to minimize the time that passes between pushing the CD tray in andbeing able to view the directory of what is on the drive.

Some drives can take a full minute or more (dirty read device?) but most vary between less than 10 seconds and upwards of 40 seconds.
