[Edited 19 jan 2014]
I have rephrased the question and added additional info about failed attempts. The presence of the CDFS partition is essential and has blocked all attempts so far; also this makes this post not a duplicate as some people have suggested.
I have a Toshiba USB 2.0 ext HDD USB device that presents itself as two partitions named Password (G:, CDFS, 20 MB) and SECURE DISK (H:, FAT32, 300GB).
The G: drive is full of driver stuff (Mac and PC), and executables in the root named Autopoll Application V1.01.exe, ONSPCLCK.exe.
Copying a 4.6 GB file to the disk fails with 'disk is full'.
How can I reorganize/reformat the drive into one partition (NTFS). I don't need the fancy options of the stuff on the G: drive.
I'm running XP.
Under hardware, properties I see that it just uses the Microsoft driver.
Under hardware, properties, details it says the following:
It has no labels or names on the housing other than the word Toshiba.
[Added 14/1/2014] Failed attempts so far:
(TL;DR: No luck yet)
Attempt 1) Disk management
I was able to remove H: bit not the CDFS partition G: There's no option for that. It is 'recognized' as a CD-ROM, probably because of the CDFS file system.
Attempt 2) DISKPART
LIST PARTITION sees G:
Volume ### Ltr Label FS Type Grootte Status Info ---------- --- ----------- ----- ---------- ------- --------- -------- Volume 0 F Dvd-rom 0 B Volume 1 Z Dvd-rom 0 B Volume 2 X Dvd-rom 0 B Volume 3 G Password CDFS Cd-rom-sta 20 MB Volume 4 E DATA2 NTFS partitie 153 GB In orde Volume 5 C SYSTEM NTFS partitie 233 GB In orde Systeem Volume 6 D DATA1 NTFS partitie 233 GB In orde Wisselbe
C,D,E are my hard disks, X and Z are mounted drives in Daemon Tools Lite
Listing partitions on disk 3 fails:
DISKPART> select disk 3 Schijf 3 is nu de geselecteerde schijf. DISKPART> list partition Er zijn geen partities op deze schijf die kunnen worden weergegeven. DISKPART> detail disk There are no volumes
(Remember I had already removed H:)
I thought "Let's be bold":
DISKPART> clean DiskPart heeft de schijf opgeruimd.
Next I started disk management and the Windows wizard for initializing disks came up.
I let it initialize disk 3, created a primary partition (H was the lowest drive letter I could assign), then let it be formatted for NTFS.
And then it turned out that the old G: partition was still there. ;-(
Attempt 3) MiniTool Partition Wizard 8.1.1
(recommended in this post)
It saw the H: partition, plus 8 MB unalloacted space, but not the G: partition I told it to wipe the disk -> Same negative result, the G: drive remains
Attempt 4) BootIce
(as suggested in Julians answer)
I told it to wipe the disk, same results. Hex editing the disk is above my powers.
Attempt 5) ChipGenius version 4
This posts suggests using ChipGenius to detect the exact make of the chip in the usb, so that you can then flash the drive's firmware.
ChipGenius failed to detect the controller part-number, chip vendor, or chip part number, Maybe not a surprise, because it's not an 'ordinary' flash pen drive.
Note that it says 'Device Name: USB 2.0 CD + HDD' and 'Product Model: USB 2.0 CD-ROM/USB 2.0 Ext. HDD' which is exactly my problem ;-)
Attempt 6) SwissKnife
(Suggested in that same forum post)
Attempt 7) GParted
I downloaded the Live boot CD. GParted sees the drive as the
\dev\sdd device (unallocated).
I tried the only option that was available 'Create partition table'. Alas, after booting back into Windows, the CDFS G: partition was still there.
I will now attempt [Knoppix]. Never seen Linux before ;-)
