a5an0 Posted October 5, 2006 Share Posted October 5, 2006 lol. yeah, linux has a way of .... healing itself.. Anyway, where I got stuck (and thought I bricked my drive) was that I ended up with the entire drive as a cdrom and it wouldnt let me reformat. which is bad. So i did dd if=/dev/zero of=/dev/sdb and let it run for a minute, Control-C'd it, unplugged the drive, plugged it back in, and I could reformat (I ended up doing fat32) Quote Link to comment Share on other sites More sharing options...
gameman733 Posted October 5, 2006 Share Posted October 5, 2006 Ok, so does NTFS hold the magic touch or what? It didnt seem to change much on my jumpdrive. Another note worth pointing out, are we editing the first byte of the partition or the first byte of the disk itself MaxDamage: just an idea, but put a hex dump of the first sector up so that we can compare whats different?

Everything gameman733 and I tried simply did not work. So another thing that could help is if you could post the images you sent Darren. (use www.kimag.es if you have to).

Darren Kitchen Posted October 5, 2006 Share Posted October 5, 2006 I'm still busy editing but as soon as this episode is kicked out the door, and I get a little nap, I'm jumping on this hack. Quote Link to comment Share on other sites More sharing options...

Jester Posted October 5, 2006 Share Posted October 5, 2006 HaHa I was thinking the same thign waiting to get home to play with it a little more.

gameman733 Posted October 5, 2006 Share Posted October 5, 2006 It would be good for social engineering. btw, if that hex is at the beginning the disk (not the partition), thats not where the bit is (assuming my pendrive works). something i did find however, on the diskprobe program that maxdamage mentioned, there is a "media flag" option under fat and ntfs boot sectors. Its really odd though, hard drives are B(something, i dont remember, at school atm) and my pendrive is set to F9 (again, i think). Setting it to whatever the Hard drives are just throws FAT out of format, and gets reset during a format. Quote Link to comment Share on other sites More sharing options...
Jester Posted October 5, 2006 Share Posted October 5, 2006 That is exactly what happens. You change the first EB into an AB which just messes you the format in Windows. Then when you click on the drive and it tells you to format it when you do so it changes the AB back into an EB. I think there is another thing in there that needs to be changed so that you can format it to NTFS. Quote Link to comment Share on other sites More sharing options...
SomeoneE1se Posted October 5, 2006 Share Posted October 5, 2006 I think it's just the drive.. becasue the drive that "works" ie can change into a HD well I have like 3 of them and if I Right click > format NTFS was always an option and it turned it into a HD when I did format one into NTFS... I would say open a U3 and try and copy over the full Hex of the drive and see if that would turn the new Drive into a U3 drive (I would guess it would need to be the same size) and see if that turns it into a U3 drive if not it might be a hardware 'mod' that makes it a U3 Quote Link to comment Share on other sites More sharing options...
amish Posted October 5, 2006 Share Posted October 5, 2006 Ok so i think i found a soloution to this problem Bascially from what ive read and heard in windows, you can make 2 partitions on a usb memorystick, edit the first to pretend its a CD drive and boom it works. When you plug it into windows, windows only recognises the CD drive and dosnt want to mount the actual memorystick. So heres my idea. I jsut found out that theres a command in windwos called "rsm" which works with removable media, in there theres a command called mount. So When the cd drive partition is mounted it shoudl autorun a payload which mounts the actual USB. Just an idea. here my dump for interest. C:Documents and SettingsAmish>rsm RSM [ALLOCATE | DEALLOCATE |  MOUNT | DISMOUNT | EJECT | EJECTATAPI |       CREATEPOOL | DELETEPOOL | VIEW | REFRESH | INVENTORY] The command line is case insensitive, except when you refer to Media Objects (including media, drives, changers, libraries, media types, slots) by their friendly names. The arguments for a command may be specified in any order. All commands return an error code - success, a system defined error code or one of the application defined error codes shown below:                 536870913: Invalid Arguments                 536870914: Duplicate Arguments                 536870915: No Guid For Friendly Name                 536870916: Insufficient Arguments                 536870917: Invalid Guid                 536870918: Ioctl Failed There should be no spaces between a tag and the actual argument. For example, for the timeout option in allocate, the timeout is specified as /t50 and not /t 50. See Start->Help (search for "Using the command line for Removable Storage") for more details. C:Documents and SettingsAmish>rsm mount /? Mount a specified piece of media. RSM MOUNT /L[G|F]<LogicalMediaID> | /P[G|F]<PartitionID> |   [/S[G|F]<SlotID> /C[G|F]<ChangerID>] [/D[G|F]<DriveID>] /O[ERRUNAVAIL|DRIVE|READ|WRITE|OFFLINE] [/R[NORMAL|HIGH|LOW|HIGHEST|LOWEST]] [/T<timeout>] The /[L|P|S|C|D]G option should be used when the LogicalMediaID, PartitionID, SlotID, ChangerID or DriveID is supplied as a GUID. The /[L|P|S|C|D]F option should be used when the LogicalMediaID, PartitionID, SlotID, ChangerID or DriveID is supplied as a friendly name. /O options:  More than one may be specified by using the             switch repeatedly. Only one of the following can be used. ERRUNAVAIL:  The mount request will generate an error if either the             media or the drive is not available. READ:        Mount for read access. WRITE:      Mount for write access. If this option is selected             completed media will not be mounted. DRIVE:      To be specified if drive guid or name is provided. OFFLINE:    Error is returned if media is not on-line. If this option             is not used then operator request is queued. /T Timeout:  Specifies a timeout in milliseconds. Default is INFINITE /R Priority: Default priority is NORMAL. C:Documents and SettingsAmish> Quote Link to comment Share on other sites More sharing options...
cooper Posted October 5, 2006 Share Posted October 5, 2006 Okay, time for me to ask yet another really dumb question. Why is the U3 partition write-protected? Yeah, it emulates a CDROM, but you can write to those too with the right software. Does autorun only work on CDs, or does it work on, say, floppies aswell?

gameman733 Posted October 5, 2006 Share Posted October 5, 2006 CDFS is a ROM based file system. IIRC, linux wont even write to mounted ISO files. Quote Link to comment Share on other sites More sharing options...
a5an0 Posted October 5, 2006 Share Posted October 5, 2006 hmmm... my real probem atm is that it works beautifly under linux, but I get the "format disk" problem that everyone else is getting. There must be some kind of flag in that first partition to say "hey, theres another partition on here!" ......thus, the magic smoke Quote Link to comment Share on other sites More sharing options...

moonlit Posted October 5, 2006 Share Posted October 5, 2006 CDFS is a ROM based file system. IIRC, linux wont even write to mounted ISO files. IIRC there's something in the format that makes writing to the FAT and TOC awkward or something, this is why it's a lot harder to edit iSOs than it is to create them from scratch... Unless you use packet writing software which works on real CDs but I don't really know much about how that works... Quote Link to comment Share on other sites More sharing options...
