I've got an old Enermax Laurette external case that has connections for SATA and IDE and I'd been using it with an old IDE drive of mine but decided to replace it with a larger SATA drive (1tb) and copy everything over...

The new drive I initialised and formatted as an NTFS primary partition on my desktop PC, transferred all the stuff I wanted to backup onto it (including stuff from the IDE drive in the external case) and then put back my original SATA drive in its place and swapped some cables around to put this new SATA drive with all the backed up stuff into the enclosure in place of the IDE drive... booting into windows 7 I get nothing but a request to initialise the drive Crying or Very sad

Panicking that all my stuff was lost in the ether, I undone all the previous steps and thankfully it's all still on the drive... but worryingly it's not being recognised in the external case, and initialising obviously means losing all my stuff.



Any ideas what the problem is and what I can do?

Try this for me, go into computer management MMC (start -> run -> "compmgmt.msc"), go into disk management, and tell me what you see for the drive.

Sounds like the external case. Try it in another case. I have a drive that is not recognized in my external case, but once I put it in the desktop - it works fine.

I would, but I don't have another case to hand.

I don't have it hooked up at the minute, but if I can paraphrase it said something like unrecognised disk, and had a red arrow that looked like it had two spokes pointing downwards. I was in a panic at the time so I didn't stick around.

If that's not enough info I can start it up again.

I am thinking the partition header has gone FUBAR, and I want to confirm this by seeing the partition as "Raw" in the Disk Management snap-in.

(seems my paraphrase was completely wrong)



unknown
not initialised

No mention of 'Raw'... good or bad? Very Happy

Yes, don't initialize it!

According to this:

It means it doesn't recognize the GPT, so probably the case is messing something up.

Thanks for the help guys. Decided not to go out and buy another case so I just took out the smallest hard-drive in the desktop, re-jiggered some files around, and put the bigger hard-drive in its place. Took a gamble and the drive I replaced works in the external case for some reason. Wonder whether it's because it's an older hard-drive or because the newer one was formatted specifically in Windows 7? Either way it's all good (if a big pain in the ass to keep things organised as drive space disappears from one month to the next Very Happy).

Well, Windows 7 formats its drives with NTFS by default, and that one should be recognizable up until NT4 at least. Wink (Unless dynamic disks were involved, but I doubt it.)

Maybe just a rare incompatibility? At least you didn't lose all the data, haha. Smile
