Salutations, everyone. I'm sorry to be yet another helpless tech-illiterate newbie, but I have searched the forum and haven't been able to find another thread addressing this specific problem, and I would be very grateful for any assistance that anyone can provide.
I own a 1TB external hard drive (Samsung H100UI/Z4). The USB-3 port on the drive's enclosure (an Iomega caddy) was damaged. Although the port was damaged, the drive itself was unaffected - I was able to use the drive and access all of my data with no problems by keeping the port physically in position until I had an opportunity to replace the enclosure.
I replaced the enclosure with a tool-free 2.5" Orico 2598US3. The caddy has a metal casing, and came with a Seal King TT6135 "HDD Protective Film" which I have not applied (the original Iomaega caddy had no such film and I'm hesitant to go sticking things onto circuit boards unless I know that I need them). The drive fits inside this enclosure without difficulty, but when connecting it to my computer (Windows 7) the drive has become unreadable. It is recognised as a disk in the Disk Manager, but the computer prompts me to reformat the drive before it can be used. As all of my data is on this hard drive, I'm naturally reluctant to do this!
Does anybody recognise this situation, and is there any way around it? Thank you for your assistance.
@kapparomeo, the reason for the differences in your sector dumps is that the HxD dump appears to have been taken when your drive was installed in your new enclosure, whereas the Roadkil dumps appear to have been taken when the drive was in its original enclosure.
Notice that the total number of sectors in HxD is 1953525168 whereas in Roadkil it is 0243995155.
1953525168 sectors x 512 bytes per sector = 1 000 204 886 016 bytes
243995155 sectors x 4096 bytes per sector = 999 404 154 880 bytes
It appears that the Iomega enclosure's firmware was configured for 4KB LBAs while your new enclosure still uses the standard 512-byte LBAs. Moreover, the Iomega firmware appears to reserve about 800KB of disc space (= 1000204886016 - 999404154880 bytes) for itself. WD's SmartWare products reserve a similar amount of space for a virtual CD (VCD), so perhaps that is what the Iomega enclosure is doing.
Sector 0 of the HxD dump appears to be a standard Windows XP MBR (the error messages are normal).
Offset 0x0B/0x0C contains the sector size. In this case it is 0x1000 (= 4096) bytes. In a standard boot sector this value would be 0x0200 (= 512 bytes).
Offset 0x28 contains the volume size of 0x0E8B1214, which is [correctly] one sector less than the value in the MBR.
In short, you will not have access to your data, either in your new enclosure, or when the drive is connected directly to a SATA port on your computer's motherboard. Your best option is to find someone to reattach the USB connector on your original PCB. Perhaps your local TV/AV repairer could do it for you.
