Hi,I'm a pretty PC savvy kind of guy, or at least I thought I was, but this has me stumped.Purchased a LaCie 250GB USB2 Ext HD. Installed the software, plugged it in. Bing-bong, new hardware found, blah-blah, your new hardware is ready for use.I open Window Explorer, no drive listed. Hmm, maybe it's not formatted. Open Disk Management, nope it's there as FAT32. I delete the partition, reformat as NTFS and create two partitions in case XP is being quirky and doesn't like the one big 232GB one.So we have -http://www.dmcity.com/uploads/LC1.gifIf I right click either drive I can open them fine -http://www.dmcity.com/uploads/LC2.gifBut, if I open Windows Explorer, neither drive is shown.http://www.dmcity.com/uploads/LC3.gifI've tried the obvious; trying different USB ports, reinstalling software, multiple reboots, kicking, cursing etc, but no joy.I can use the drive in a long winded, cut n paste fashion, but ideally I'd like to use it like any other drive and drag and drop to it from WE.System: Dell 8300, 3.2ghz, 2GB RAM, 9800 ProSuggestions anyone?

Hi Dean,You've probably thought of this but TweakUI has an option to hide selected drive letters. Might that be the reason?Cheers,

Ray,I don't have TweakUI installed on that PC :(Ta neway.

Dean,Nevertheless it might be worthwhile installing it to see the state of your drive letters. Other than that I can only think it may be a Bios setting but as to which one...???Cheers,

Problem solved with a reg hack. Thx Rob.HKEY_CURRENT_USER SoftwareMicrosoftWindows CurrentVersionPoliciesExplorerDo you see a NoDrives key ? If you do then the binary/decimal data should look something like thisName. . . . . . . . . Type . . . . . . . . . DataNoDrives . . .. . . .REG_BINARY . .. . 02 00 00 00If not change it to this setting as it should then show all drive letters.

Dean,I am having problem with the letter assignment on my external drives.I change them to the way I like it with Disk Management. But once I boot up again the letter assignments are changed again.Can I use Reg Hack to make the letter assignments permanent? Where do I get Reg Hack?Appreciate any help.Thanks.Abe
