501751 2006-11-24 08:00:00 Hi all,

Just wondering if anyone knows if there's a way of making an external IDE HDD ''appear" (to a computer) as a flash drive? I have some equipment that will read data from thumb drives but not from an external HDD.

Tried both NTFS and FAT32 formatting on the HDD so far (can't work out how to format the drive as FAT16, but due to the 2GB partition limit I don't think this will help anyway). Is there a special kind of format used for flash drives?

Thanks.

501752 2006-11-24 08:41:00 As far as I know, pen drives are normally formated in FAT32. But his is only since this is a fairly universal file systrem able to be read by most OSs. You can format a pen drive in whatever you want I think - but I have not tried. Even though I am a Linux user, USB drives stay in FAT32. johnd (85)
501753 2006-11-24 08:49:00 You need an external USB case which you should put the hard drive in (you cannot boot normally from an external drive though). Format the hard drive in FAT32. If that fails, try formatting it in FAT16 (this will limit the size to 4GB).

For realistic flash drive integrity problems, you can try hitting the hard drive with a hammer after writing to it a few thousand times.

501754 2006-11-24 08:54:00 FAT16 (this will limit the size to 4GB).

FAT16 max partition size is 2.1Gbytes

Ah, so it is! My mistake.

501756 2006-11-26 02:35:00 Yeah sorry I should explain this a bit better. I have an external HDD (in a USB case) that I'm tying to get to work with a home theatre receiver. The receiver seems to 'see' MP3 files etc on flash drives but not on the HDD.
I've noticed that if you connect a flash drive to a PC it appears as a 'removable disk' formatted as 'FAT'. If you connect an external HDD it appears as a 'Hard Disc Drive' in My Computer and formatted as 'FAT32'.
I've only been able to experiment with 128MB and 512MB Flash drives so I have to assume they could be FAT16 but someone might be able to confirm that even 2GB or larger flash drives appear as Removable Storage in My Computer?
Thanks for all your help so far!

501757 2006-11-26 02:47:00 Try formatting it with FAT16 instead of FAT32. I'm not sure how to do this on Windows. The home theatre probably only supports the FAT16 format (many portable media players are the same). You will be able to use only 2.1GB of space on the hard drive though. TGoddard (7263)
501758 2006-11-26 02:51:00 Most usb flash drives are detected as usb mass storage devices.

Even the digital cam here is detected as a mass storage device.

And the 1GB Sandisk flash drive here gets detected as a removable storage in my computer. And is in FAT format.

501759 2006-11-26 04:39:00 Yeah that's the weird thing. I assume that all camera memory cards and thumb drives (regardless of if they are bigger than 2GB) so basically what I'm asking is "can you make an external HDD appear as a USB Mass storage device?" joe_exception (2874)
501760 2006-11-26 05:04:00 I have a 40GB HDD in an external case, partitioned into 3 drives, formatted FAT32 and connected via a USB 2 . 00 interface . It is recognised by W2K as an external USB device in exactly the same way as my digital camera or my flash drive .

Can't tell you more than that, it just set up that way from the get-go but clearly it should be possible to do what you want .

Cheers
