sgbrito Posted February 12, 2005 Share Posted February 12, 2005 Hi all,I have a USB external HDD and when I plug it (Windows XP, SP2), it works fine. Windows recognizes it and a new drive (I:) appears in Windows explorer.The problem is, when I reboot the PC, Windows explorer doesn´t mountautomatically the HDD (I:).I need to unplug the HDD and plug it again in order to access the HDD (I:)Does anybody know how to solve it ?Thankssgbrito Link to comment Share on other sites More sharing options...

sgbrito Posted February 15, 2005 Author Share Posted February 15, 2005 Hi horsecharles,Thanks for the info, but my problem is a little bit different from theirs.Every time a plug the hdd, it works fine, Windows Explorer maps the drive (I:).If I keep the hdd plugged and (reboot) or (turn off and turn on) the computer,Windows explorer doesn´t map automatically the drive. I have to unplug and thenplug the hdd in order to access the hdd.Thanks anywaysgbrito Link to comment Share on other sites More sharing options...
horsecharles Posted February 15, 2005 Share Posted February 15, 2005 Sorry to hear, sgbrito My next thought, since this is USB, is power(btw let's list everything & let you discount what's obvious-- to avoid missing something if we assume you already did / know, & to completely eliminate each possible suspect one by one, even if not likely):First, though, i'd enable bootlogging to see if anything not only failed to load, but if it took extra long-- and as well system info & event viewer may hold clues-- scroll down at this page if you require the steps to do so:http://www.microsoft.com/resources/documen...mc_str_xhtz.aspAnd when you looked up both updated mobo & the usb disk drivers, was there any mention on either site about a know issue w/ any XP patch / pack(there've been specific USB firmware upgrades released for SP2).....When you looked in Device Manager for anything untoward, in the drive's Properties was udma enabled(and as well in windows & bios udma enabled)...I would toggle off all hibernate & standby in both windows & bios..IF possible switch port..... both for it & any other usb peripheral...Connect drive to another computer, change cable.....Physically turn off & disable in Device Manager as many peripherals as possible, and as well unplug them inside the case: this not only to see if there's a power issue, but when you re-enable them they may all load in different order, which maybe also could be a cause... Also, when you reconnect them inside, try to re-connect them all to defferent slots than they were individually plugged into before(do this as well for all other peripherals possible)-- the reason here is that there's a small chance that an irq assignment may be causing a conflict between devices-- and more than likely your pc's original installation mode(acpi) precludes manually changing irq assignments-- this trick will cause them to be grouped / assigned differently & just maybe........

zac68 Posted February 16, 2005 Share Posted February 16, 2005 It might be a Bios issue as well. Check out you Bios options for USB and try some of the alternative options it presents you there. I had some issues with a USB hdd and resolved it at the Bios level. Link to comment Share on other sites More sharing options...
