I have a 250GB Western Digital HD that I use as my primary HD for storing data. Recently, I’ve been having problems with the HD. For instance, when I try to burn a disc (DVD or CD) using this HD as the source burn times take much longer. I notice then when burning using either NERO or DVD Decrypter that the read buffer does not stay full anymore, and at times it is completely empty! In NERO I’ve seen messages like: “Can only write at 2x instead of 4x, because the speed of the source is too slow” My DVD/CD devices all are using DMA mode, but it looks like my HD is using PIO. Following is a snip from my NERO logs: === Scsi-Device-Map === DiskPeripheral : WDC WD1200JB-00EVA0 atapi Port 0 ID 0 DMA: On CdRomPeripheral : _NEC DVD_RW ND-2510A atapi Port 3 ID 0 DMA: On CdRomPeripheral : SONY CD-RW CRX195E1 atapi Port 3 ID 1 DMA: On DiskPeripheral : WDC WD2500JB-32FUA0 15.0 ultra Port 4 ID 0 DMA: Off DiskPeripheral : WDC WD2500JB-00FUA0 15.0 ultra Port 4 ID 2 DMA: Off CdRomPeripheral : Generic DVD-ROM 1.0 d347prt Port 5 ID 0 DMA: Off CdRomPeripheral : Generic DVD-ROM 1.0 d347prt Port 5 ID 1 DMA: Off I don’t know if this is the issue, since I never examined the logs before. The 250 GB Western Digital HD is connected to my machine via a PCI WinXP Promise Ultra133 TX2 (tm) IDE Controller. Due to this, I can’t seem to access the individual HD via the IDE ATA/ATAPTI Controllers section from the device manager to set it to DMA. I tried uninstalling the WinXP Promise Ultra133 TX2 (tm) IDE Controller from the device manager and reinstalling the device, and even tried changing the PCI slot. Nothing seems to work. I did verify though that I can burn from my main 120 GB HD (which according to NERO has DMA on) without issue. I’ve also freed up over 100GB of space on the HD as well as defragment the HD. I’m at a loss as to what my next steps should be. Any help is much appreciated. Thanks!
I have 5 physical devices that are hooked up as follows: On my mobo: IDE1 120 GB HD on primary as master IDE2 DVDRW on primary as master / CDRW on secondary as slave On my PCI WinXP Promise Ultra133 TX2 (tm) IDE Controller IDE1 250 GB HD on primary as master IDE2 250 GBHD on primary as master The HDs on the promise ultra are the ones giving me problems. The other 2 CDROM devices in the Scsi-Device-Map are from daemon tools.
you have both hd drives on primary as master which if on same cable can't do as they conflict so that is causing your problem. try this instead- 120gig as master with DVDRW as slave both on the primary port, both 250gig hds set as 1 master & 1 slave on the secondary port & the cdrw as master or slave on the ide card
I actually do not have both HDs as master on the same cable, they are each on their own cable on their own IDE channel. I could try to mess around with the cables, but it was working perfectly before, and I was going to resort to swapping cables around as a last resort.
your info you posted said "IDE1 250 GB HD on primary as master IDE2 250 GBHD on primary as master". as a motherboard & a controller card normally has 1 primary & 1 secondary ide ports so that is what i used in my reply
I finally resolved my problem Don’t know what happened, but let me walk you through my steps and my findings. Based on several people’s suggestion that the problem was that the HD was not in DMA mode I tried to research how to change this. Googled for days could not find anything so I switched my setup for my HD to just run off my mobos ide channel. Now it say’s it’s in DMA mode but I still have the same problem as before and my read and device buffers don’t stay full. So I try the registry hack, uninstalling the IDE device from the device manager, and also install XP sp2. None of these do the trick, UG! So know I think maybe something is wrong with my WD HD. So I run a Windows Check Disk, Defragment my HD again, did a virus scan with updated defs, ran WD Data Diagnostic Tools, and bought new rounded IDE cables just in case. Still not working! Then while searching the boards for a possible solution I ran across http://pcpitstop.com/. They do an online check of your system and determine the health of your machine. One test they run measures your HDs uncached disk speed. For all my HD’s I was getting around 50 MB/s, but for my 250GB WD HD it was around 15 MB/s. Eureka, looks like that is the problem but what is causing it? Their site also mentioned that maybe it might no be running in DMA mode, but I tried all the tips and tricks already so I knew that wasn’t the case. So then I figured oh well let me just start fresh, so I removed all my data off of the HD. Ran WD Data Lifeguard tools to completely wipe out the hard drive and write 0s. Destroyed and recreated my primary partition. Then I reran pcpitstop’s test and low and behold my HDs uncached disk speed was now 55 MB/s. Looks promising! Tried burning a couple disks, SUCCESS Moved the HD back to the PCI IDE Controller (still says DMA mode is off in the Nero logs), burned a couple more discs, SUCCESS Don’t know what happened to my HD, but it looks like it had nothing to do with DMA mode being on or off (at least in respect to what the Nero logs were saying).
