BigDawg: first responses are: BWeb50 said: Two things you might want to try. Make sure you have the drive plugged into a root USB connection on your machine, that is, you do not want a USB hub between the external hard drive and your machine. Some devices just don't want to cooperate when connected to your machine via a hub. Second, if this is not the problem, do an uninstall of the drive, then reinstall. There may be a glitch from formatting the drive.

Hey Everett. Thank you for "adopting" my problem. I appreciate any and ALL help in this matter. This problem is extremely frustrating to me. This external USB Drive was meant to be a network storage drive for the 6 computers on my network here at home. Currently it is unreliable as a "write to" drive but it works fine as a read drive once I actually manage to get data successfully sent to it. Sometimes it takes me 5 or 6 attempts (each attempt requiring a full reboot of the server machine that the external USB is plugged into) to copy whatever file(s) I am trying to put on the USB drive. I will continue to review any and all suggestions and try to figure out if any of them apply to me. One question about the suggestion from Bweb50. How do I determine if the USB Drive is plugged into a root USB connection? The USB 2.0 PCI Card has 4 USB Ports on the card and 1 cable USB connection that feeds to a USB port on the front of the machine. I currently have the USB Drive in the far left port on the card itself so I would think it is plugged into a root connection but not knowing intimately the workings of USB I might be mistaken. And to his having a faulty drive I wonder how he determined it was a faulty drive? Did he find bad sectors or what method did he use to make that determination? The drive does not have bad sectors. That much I can verify 3 times over. But then my next argument would be that if it was a faulty drive would it still lock up the PCI bus when the drive failed or just give me a drive write error? Again Everett, I appreciate all your assistance. One day soon I hope to finally be rid of this problem. One thing that makes me rule out a bad drive is the fact that when I did take it to that local computer shop he did hook up another USB drive and it locked up the system with that drive as well. Then he said he even tried a different USB 2.0 card and that locked up the system. I found a very obsure reference to something about maybe my very motherboard chipsets might be possibly the problem? But the posting I saw on that was vague and was not exactly my symptoms. Just in case my motherboard specs are: MSI MS-6501 (v1.X) ATX Mainboard AMD-760 MPX Chipset based K7D Master series. I have been to MSI's website and verified that I have the most up to date bios for my motherboard. If there is any of my system specs that you need or you think would be beneficial let me know and I will be glad to post them.

BigDawg, BWeb50 uses the term root hub to mean to try plugging the Maxtor directly to the USB port on your computer (which you have effectively done already). I still recommend trying a connection with a powered hub (which gives you more external ports) between the Maxtor and the USB port on your machine; this would require you to switch from your current configuration which is directly to the PCI card. as for the possibility of a faulty drive, run an error check on the external drive; click Start, double-click My Computer, right-click the Maxtor drive and select Properties, Tools tab, in the Error checking area; select the Check Now button, check both disk options and Start. if you prefer to use the Command Console; click Start, Run, type: cmd at the command prompt type the following commands and press the Enter key after each command: cd\ chkdsk e: /f where e should be changed to the drive letter assigned to the Maxtor. DoctorD's Maxtor web site states that the maximum file size that can be transferred to a FAT32 formatted storage device is 4GB. to backup a file larger than 4GB you must must format the storage drive as NTFS. will keep you advised of any further replies from the other forums...

Thanks for the follow-up. In my original post I stated that I had already triple checked the drive for errors. I did a through scan. It is formatted for NTFS also. I did this the very first day I had the issues when the drive had nothing on it. Then later after I had transferred several gig of data to it then again about a week later after a friend told me over and over it had to be bad sector on my external drive. So I have ruled out the bad drive and also the NTFS formatting issue. Both of those were ruled out before I ever even posted here. As to the powered USB Hub I will look into buying one of those and giving that a try. Can't hurt at this point. I have exhausted about every other option I have been told to try. =\ Maybe I am just stuck with this particular problem using my current computer and hardware. Once again Everett. Thanks so much for replying. If not for your time and efforts I would still be wondering about alot of potential problems. At the very least we have been able to find out what the problem is NOT! hehe. That is not a bad thing. It just narrows down the possibilities.

I've a similar problem with my 40gb Fujitsu. The difference is my pc/laptop do not get lockup, instead I receive an error message indicates that window cannot find the file and path, and the copy fails and the HDD is removed.

BigDrawg, I think I just fixed my problem. My HDD has a power supply input and also came with a power cable, I did not use it before because the other end of the cable has to plug into a ps/2 port and my laptop does not have a ps/2 port. I brought a USB to ps/2 adapter and plug the cable to a spare usb port, and I tried to copy the file that I had trouble before, and the copy finished successfully. Your problem may be related to not enough power to copy large file or folder with many files. Give it a try. Good luck.

ed: thanks for posting back with your solution; that may well help other folks. BigDawg: received no further input yet from the other forums. did the powered hub help?

I have EXACTLY the same problem, with the difference that it also locks even when it reads only. I noticed that you have AMD processors, just like me. I have tested also the HDD in other (intel) computers and it works flawlessly. I'm beginning to believe that it has sth to do with VIA chipset that my motherboard has... I'll try the services to start automatically, to see if anything changes, but i doubt it.

I have had the same problem with two different manufactures of usb 2.0 external hard drives. I run Windows XP and had connected directly to my usb 2.0 hub on my laptop and through an adaptec xhub 7+ 2.0 hub, and still have the same problem. My experience has been the NTFS file system through usb 2.0. Whenever I format and partition my 80 and 120 GB drives for FAT32 (partitions less than ~30 GB and file sizes less than 4GB), the drives really zip on over. However, when I reformat to NTFS (any partition size), it always slows down to a crawl, and most of the time fails to transfer. I email the external HD manufacturer and all they said was "reformat" again, and if that didn't work they would repair or replace. It didn't sound like they had ever heard of it or were denying it. Good Luck and I'll try to follow up if I find anything.

I have had the same problem. I found out in another forum the following reply: - Run regedit - go to: HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E 967-E325-11CE-BFC1-08002BE10318} - make a backup of this key - Delete the entry "LowerFilters" It should do the trick Hope this Helps. Henri

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318} Sorry there was a space left between 4D36E and 967 ControlSet could be also found as ControlSet001 Regards, Henry

I checked that key as suggested. Here is what I found under the key. HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E97E-E325-11CE-BFC1-08002BE10318} Default : REG_SZ : Other Devices Class: : REG_SZ : Unknown Icon: : REG_SZ : -18 Those are the only 3 listed. Is my registry entry missing something? I will wait to hear back if you have any further info on this matter. Thanks for all the responses too. This problem has been driving me to drink. I still have not gotten a powered USB Hub. Not from a lack of trying. Every time I go to get one they are sold out. But I will get one as soon as I can find one to buy. =\

BigDawg: no LowerFilters on mine either, but the other sub-keys had what appeared to be more relevant data. my suggestion is to amend or add the following and see if it makes a difference; (Default) REG_SZ Disk drives Class REG_SZ DiskDrive Installer32 REG_SZ StorProp.Dll,DiskClassInstaller UpperFilters REG_MULTI_SZ PartMgr have three more sub-keys, but try the above first and let me know if it helped... p.s identical entries per above found in both CurrentControlSet and in ControlSet001.
