A friend brought me a Vista 32 bit machine very very slow: Safe Mode can take 1 hr. or more to load. I suspected "PIO" mode, instead of DMA Looking at Dev. Mgr. "IDE/ATAPI" Looking at each entry here & clicking "Advanced Settings" DID NOT (EVER) SAY ANYTHING, NO PIO, DMA ALL FIELDS BLANK, at: dev. mgr > IDE/ATAPI > advanced settings. Try system restore not available or won' start. I then looked at: HKLM\system\current control set\control\class 4D36E96A-E325-11CE-BFC1-08002BE10318 here: 0001, 0002 (right side windows pane) identified as IDE but "Master Data Check Sum" & similar for slave were MISSING Next: from safe mode with net: Ran Rogue Killer found Rogue.FakeHDD system restore PID 1732. Removed Next HitManPro - removed about 6 malware, & many traces Still slow, appropriate timing instrument is a SUN DIAL. Tried system restore, from safe mode, (user said machine OK on date x), it took a long time & I missed going back to safe mode (upon reboot), 2 hrs & normal windows failed, to load. Not sure but suspect system restore failed. Next, booting from UBCD 4 win, the machine was quick very peppy, so now I'm back to thinking PIO mode. Spinrite found no errors, or SMART issues _________ Would deleting (DEV MGR) ide/atapi drivers, would windows just replace, upon reboot. Seems logical as its a protected file I've seen VB Scripts for this, but not sure if it's for Vista, or does it matter (PIO to DMA) Thanks Rico
