Ripping / Playback Speed.

[tjborwn101]

I'm notcing a wierdity and wanted to see if there was some common thread or reason behind it.

I have a ThinkPad (work) and Dell Inspiron (home) (both P3-600ish)

I also just built a new P4-2G system that includes two IDE (CD/DVD)Drives hooked in the secondary IDE connector on my MB.

Running proggies like Shrink and Clone or even Roxio Creator Classic I am noticing a considerable speed difference between the laptop based DVD Roms and the Desktop DVD Roms. The laptops are running circles around the desktop devices and the time is about 1/2 what it is taking on the desktop.

The Desktop Drives are a Maddog 16xDVDROM/CDRW (slave on second IDE) - the master on the IDE is an old CDRW....and a TDK DVD RW. (via 1394).

This morning on my desktop I started to create an ISO file of DVD ROM -- 30-40 minutes later it was only 20% done...I stopped it. I just started the same process here at work (IBM laptop) (writting to a server HD no less) and it finishedin 30 minutes.

Any ideas... any way to 'pump up the volume' so to speak on my desktop to increase DVD ROM Reads / throughput.

Thanks in advance

I checked the advanced settings of the IDE controller in my device manager for the DVD ROM's -- it is Ultra DMA Mode 2 (HD's are Mode 5).... same as laptop.

After reading posts here and elsewhere I thought that was going to be my resolution in that it may be set to PIO not DMA... but it isn't.

Any one have other ideas.

I might be missing something (wouldn't be the first time) but exactly where are you ripping from on the desktop machine (what drive, channel) and where is the rip going (assume hard drive on IDE-1 Master).

Whether I am copying content from DVD ROM (IDE Secondary / Slave) or using a DVD copy tool (Shrink, Clone, DVDcopy2) to move content to IDE Primary / Master my speed is not great... (per thread above)

All I can offer (and you might have already checked this out):

1. A jumper setting is wrong somewhere. I noticed a considerable degradation recently when I mistakenly did not notice a newly installed WD hard drive was jumpered as Master with a Slave instead of Master Alone on the Channel (it was alone on the channel). Surprised me that something NOT there could cause a slowdown to something that was there. I have a friend who fought similar problems with "cable select" instead of specifically jumpering the drive.

2. A bad cable causing retries.

3. Your hard drives are a little small (30 and 20 if I remember). Depending upon where your pagefile is, what size it is, and how full your C: drive is, any fragmentation could cause you some problems. This is especially true IF the files you are transferring are large. If contiguous space is not available, Windows will "hunt" for enough space and spread the file out requiring frequent head repositioning and FAT table updates.
Running scandisk and defrag would be a good idea.

4. Might be worth looking at the Maddog rip/read speed. DVD Decrypter will give you a good readout of max and average rip speed. Not unusual for a drive to be "locked" at 2X when ripping. More so true with burners but an easy and free test to run.

5. Download, install, and run Intel Application Accelerator (free at their website). Also download the free program AIDA32 and look for conflicts. Run their benchmarks for memory. They also give you a comprehensive display of your hard drive specs (read / write rates, buffer size, SMART logs).

All I got for now. Hope it helps.

Jayhawk... Thank You for your effort and time
