PC hardware forum: External IDE HDD Not Recognized - Please Help

provide it with sufficient power? Any USB y-cable or addition self-power cable? Chances it's underpowered.

Thanks for the replies. It is being powered by AC, and I have tried multiple USB ports, both in the front of the computer and back.

I've seen that happen when the USB port is USB 1.x.

Your post left out details but look at the second screen at http://www.thecodingstudio.com/opensource/linux/screenshots/index.php?linux_distribution_sm=GParted%200.3.9-13

Now go get GPARTED and share what you see on that screen.
BE DETAILED.

Sorry but I can't find what enclosure you have, a manual to that enclosure and what jumper setting is required and finally what jumper setting is on the IDE drive.

You can see this happen if that jumper is wrong.

HOWEVER since there are only 3 settings, why not try all 3?
Bob

It does not show there until there is something to show.

That is, a partition with a good format. And there is no reason to think that we can partition, format the drive and then slip it into a case. Sometimes works, sometimes not.

Since I can boot GPARTED without issue why was that not done? I won't discuss that VM idea again.

As to IDE, if you don't have access to such on any PC then that's a dead end.
Bob

If common tools and software are not usable then this drive and case are best returned to get your money back.

Get a ready to use case next time.

PS. The VGA card fan killed by GPARTED? I've heard far fetched stories but this is definitely one of the better ones that could be used to keep people from fixing their own machines.

whether the drive is OK independent of the enclosure. I would jumper as CABLE SELECT if installed internally for partitioning and formatting.

Sorry but all that meant is that sata on the other machine is configured as RAID and not your usual single drive setup. Not to duplicate the manuals and web content on that other machine but changing that could cause some machines to stop booting so only do this if there is nothing to lose on the other machine.

Ok so I did connect my hard drive to a computer via IDE and it started up fine. Then it said that it needs to be activated and formatted. I did those two things. Once it was all completed, everything look awesome. I made a name for it, I assigned it a drive letter, and I could even move files to it. But then, I turned off my computer, inserted the hard drive into my enclosure, plugged it into my computer, and it still does the same thing! It is only recognized by Device Manager, not my My Computer. What is wrong? I don't think it's my enclosure because I have used this enclosure with this exact hard drive and it used to work fine.

Ok, so I just got another, new hard drive enclosure. I pop in my hard drive and connect it to my computer. It is "recognized", but AGAIN, it does not show up in My Computer. I check "Device Manager" but now it detects it as just a "Disk Drive", not "HDT722516DLAT80". So I guess now we know that it must be something with the hard drive, but as I said earlier, I put it in a computer directly via IDE and it is recognized fine. I can do everything with it, but with hard drive enclosures, it doesn't work. I have used this hard drive with a hard drive enclosure a couple of months ago and it worked fine, but now it's not. Any help guys? Thanks.
