Multibooter Posted March 20, 2009 Share Posted March 20, 2009 (edited) I'll give that a test tonight, see what it does, before I start the surface scan.I doubt the surface scan will be of much use. How about clearing the USB disk & then partitioning it into a single logical partition, 160GB is Ok on USB? My partitioning tool of choice for Win98/FAT32 is PartitionMagic 8.01, which can partition external USB drives.My next step would be try the shutdown/restart sequence with another make of external USB HDD.You could also check whether it's the fault of nusb, which I would doubt: 1) with your Acomdata USB drive connected, rename Windows\INF\USBSTOR.INF and USBSTOR.PNF to something like\Usbstor.inf.deactivated and usbstor.PNF.deactivated New devices will not be detected by nusb anymore2) go into Control Panel -> System -> Device Manager select (probably under Disk Drives) the Acomdata USB drive -> click on Remove3) reboot4) install the Win98 driver from the Acomdata CD5) reboot again, when your system is up again, plug in your Acomdata USB drive, Win98 should detect it Ok6) shutdown/restart again, with the Acomdata drive connected: do you still have the same problem?To re-activate nusb for installing other devices: just rename the renamed USBSTOR.INF & USBSTOR.PNF to their original names.

dencorso Posted March 20, 2009 Share Posted March 20, 2009 Well, despite the error message, USBD is not a VxD, but a WDM driver. BTW, what version of USBD.SYS do you have in your system? Link to comment Share on other sites More sharing options...

jaclaz Posted March 20, 2009 Share Posted March 20, 2009 If I get it right, the PC tries, no matter what the settings in BIOS are to boot from the external USB if it is switched on at boot time. If this is the case, it is possible to workaround the problem. Which exact "crash" do you experience (are you getting a readable error - if yes post it EXACTLY as you see it - or a flashing cursor or j in the top left of screen or whatever - please describe it).One can install on the external USB stick a MBR/Bootsector or loader that actually boots and then passes control to the internal drive.Tests must be made to check whether drive numbers are shifted and a disk BIOS swap is needed or not.This technique is used commonly for the "Install XP from USB" using grub4dos.jaclaz Link to comment Share on other sites More sharing options...

My partitioning tool of choice for Win98/FAT32 is PartitionMagic 8.01, which can partition external USB drives.But I don't have PM 8.01. I haven't used PM since v3.0. I use BiNG for most jobs now,but for some reason this AcomData unit causes EVERY system I've tested to LOCKUPwhen it's powered ON outside of windows. Within a windows environment, it's A-OK.But outside windows (ie, DOS and BiNG) it's instant system LOCKUP. So it appears theonly hope of resizing it is with a partitioning tool that handles USB from within windows,OR removing the disk from the AcomData enclosure and installing it on an IDE cablein a system with a newer BIOS than mine (ie, one that can "see" a drive > 128GB).Unfortunately, I don't have such a system available whenever I need one!On my ABIT mb it seems the BIOS detects anything > 128GB as a 128GB disk.Apparently the BM6 BIOS also limits what BiNG can do, because BiNG would notpermit more than 128GB to be used when it partitioned the 160GB disk.

joe tweaker Posted March 20, 2009 Author Share Posted March 20, 2009 If I get it right, the PC tries, no matter what the settings in BIOS are to boot from the external USB if it is switched on at boot time. I don't think it is actually trying to boot from the USB, because if I do a Step-by-Step confirmation during a restart, it processes my Config.sys, Autoexec.bat, and loads all windows drivers before a BSOD appears. If it were attempting to boot from the USB drive, all these files would be missing as there are no files saved to the USB drive yet.Which exact "crash" do you experience (are you getting a readable error - if yes post it EXACTLY as you see it - or a flashing cursor or j in the top left of screen or whatever - please describe it).The exact error is listed in post #1 of this thread, third paragraph from the top. I went back and highlighted it just now to make it easier to find.It appears more likely to me that this drive just isn't designed to work correctly OUTSIDE of windows. It refuses to "play nice" when powered ON anywhere OUTSIDE the windows desktop. ie, DOS, BiNG, or while windows is loading. This makes it all but impossible to use third party tools with this drive outside of windows. Link to comment Share on other sites More sharing options...

I have not tested her WD Book Drive on my system as we live miles apart and she has too much data stored on it to "loan it out." But I can state that neither of her TWO external drives exhibit the issues on her system that the AcomData exhibits on mine AND on hers.

thydreamwalker Posted March 20, 2009 Share Posted March 20, 2009 Same problem with W2K Server ....it has to do with a newer update?...i think?as all was well until new flash and March updates were installed 1-2 weeks ago! Link to comment Share on other sites More sharing options...
joe tweaker Posted March 20, 2009 Author Share Posted March 20, 2009 Well, this Amazon review confirms I am not the only one seeing this issue with AcomData.This doesn't prove the drive is at fault, but it certainly lends support to that idea.http://www.amazon.com/review/RS8PPLA6BGJ2X...t#RS8PPLA6BGJ2X Link to comment Share on other sites More sharing options...
dencorso Posted March 21, 2009 Share Posted March 21, 2009 It seems to be some quirk peculiar to the AcomData enclosure. And, yes, you're not alone... Google returns many similar cases. See, for instance:10.5 certain external drives not mounting after restart or sleep; 10.4 ...after sleep, and this one that's more similar to your case:Acomdata 1T USB drive issue.

jaclaz Posted March 21, 2009 Share Posted March 21, 2009 (edited) @joe tweakerI misunderstood the symptoms, sorry. Can you try running Chipgenius on the USB enclosure?Here:http://www.boot-land.net/forums/index.php?...c=4661&st=0Maybe this way we can pinpoint the "problematic" controller, there may be a "manufacturer tool" available for it.@dencorsoThe one you found:http://www.techsupportforum.com/hardware-s...-usb-drive.htmlseems like a report confirming my initial idea (wrong MBR/bootsector and attempt to booting from it)The one on the "mac" forum seems like it. jaclaz Edited March 21, 2009 by jaclaz Link to comment Share on other sites More sharing options...
Multibooter Posted March 22, 2009 Share Posted March 22, 2009 (edited) ... seems like a report confirming my initial idea (wrong MBR/bootsector and attempt to booting from it)When I clone the main 120GB HDD of my Inspiron 7500 laptop to a another HDD in one of the 2 drive bays of the laptop, and then put the cloned HDD into another nearly-identical Inspiron 7500 as main drive, the cloned HDD works fine, no errors detected by PartitionMagic 8.01 or Partition Table Doctor 3.5. But when I put the cloned HDD into a USB enclosure, PartitionMagic reports disk geometry errors (255 heads vs 240 heads) and displays the cloned disk as Bad, even if Win98 Explorer can handle it Ok. Partition Table Doctor 3.5 also finds unrepairable errors in the partition table of the cloned HDD put into the USB enclosure. Acronis Disk Director 10 finds no errors. The BIOS of my old Inspiron 7500 reports at POST the internal 120GB HDD as 65535 MB.When I clone the main 120GB HDD of the laptop to a USB drive, and then insert the cloned HDD into another Inspiron 7500 as the main drive, the Inspiron will not load Windows and has an error msg on a black screen.Again, as long as I clone the internal HDD to a HDD in a drive bay module, the cloned HDDs work fine as the internal HDD of another Inspiron 7500. But I never clone (or partiton) a HDD in a drive module for use in an USB drive.This may be related to joe tweaker's problem, since he has partitioned the HDD inside his desktop, and then uses it in his USB drive. Maybe joe tweaker should partition the Acomdata HDD in the Acomdata enclosure, not inside of his desktop.

For my next deployment of an internal main HDD to my old Inspiron laptops (in about 2 months) I will try to:- clone the internal HDD to an external USB HDD- then change the partition type from currently 06h [= FAT 16B greater than 32MB] to 0Eh [=FAT 16 LBA] while the HDD is still in the external USB enclosure- then insert the cloned HDD from the USB enclosure into another Inspiron, as its main HDDIn about 2 months, after my next deployment, I will post here whether PartitionMagic still reports a disk geometry error when the USB-cloned-HDD is inserted into the Inspiron laptop as main HDD. On the HDDs which I am currently using I don't want to try changing the partition type, I don't want to get into trouble now.PartitionMagic v8.01 build 1312 cannot change partition types. Acronis Disk Director 10.0 build 2117 can change partition types, but does not list 0C or 0E in its partition type menu.Paragon Partition Manager 9 (is about the same as V-COM Partition Commander 10) and Partition Table Doctor 3.5 CAN change to partition types 0C [=FAT32 LBA] and 0E [=FAT16 LBA]. Which of the 2 tools would you recommend for changing the partition type to 0E? My gut feeling is that PTD works better on partitions used by Win98 than Paragon Partition Manager.BTW, I have been using in the extended partition of the cloned HDD a mix of FAT16 [type 06] and FAT32 [type 0B] partitions. Should I also change for the next deployment the partition type of the 2 FAT32 partitions inside the extended partition from 0B to 0E? On one of these FAT32 partitions inside the extended partition I am using WinXP. Or is it sufficient to change the partition type only for the FAT16 boot partition C:?Another complication may be that I am using as boot manager on the Inspirons old System Commander 2000 v5.01 (on my desktop I have installed newer v9 for Windows Vista), which installs its own MBR.@joe tweaker:Did the partitioning of your HDD inside of the USB Acomdata enclosure solve your problem?
