When the system booted, the Maxtor was given a drive letter that corresponded to one of my other drives (H-Drive, so I changed it to Z: and, guess what? I can now see it.

I watched the drivers load and nothing unusual happened except it found all drives this time.īack to the Maxtor Mini OneTouch and not being visible as an icon under "Computer".
#Seagate external hard drive says nothing is on it for mac driver
Guess what? When I next booted, the driver installed correctly and it was visible in the Device Manager and in Disk Management, but not as an attached device under "Computer." But here's the more bizarre part. However, just for grins, I plugged it into a rear USB port to see if there might be a power differential. In all of my troubleshooting, it never did this. When it sees insufficient power, the activity light blinks at a periodic rate and it won't mount. The Maxtor is one of those drives that pulls all its power from the USB port - no external PSU. Earlier in the process I set it back to High (480mbps). The adapter I'm using is just that, not a spare case - and it is a handly little bugger to, right? And I ruled out it as a problem since drives connected to it were visible in XP.Īlso, my BIOS only has two settings for USB I/F speed (Full and High). Couple of points here (back to Trouble) I didn't address. Best guess I could come up with, but I really don't suspect the OS is at fault.Īh, the vaguaries of Windows. I would imagine that you have tried multiple ports on your windows 7 machine, so the only other thing that I would suggest is that perhaps the USB port on the machine is not supplying sufficient power in the form of mA per port (milli-amps), try rebooting the machine with the adapter and an external hard drive attached just as a test. I have had and used several of these adapters over the years, as they do not seem to be very durable so I've replace a few when the seemed to stop working. Other than that Windows 7 doesn't seem to have any problem seeing the external drive, I use it frequently to help friends and family recover files from otherwise unbootable systems, before attempting further repair steps, without problems. It's an adapter, not an enclosure, so if we are on the same page, the only issue I have ever had in doing this was when I was attempting to connect through an unpowered USB hub. I use a similar connector, I think manufactured by Sarbent, to connect 40 pin IDE (66, 100, 133) as well as 44 pin notebook hard drives and SATA drives to a USB port on my Windows 7 machine. Anyone have any other ideas or comments (please withhold any preachy stuff about building your own or external case electronics - no need for any more silly and inexperienced jibberish).
So I'm guessing there's a problem with Win7 and IDE/ATA drives. I have an external 1TB drive that is eSATA and it works. W7 Troubleshooter doesn't recognize the device as having a driver problem - just an unknown USB device. They don't show up in the "Safely Remove Hardware & Eject Media" utility. In the "IDE ATA/ATAPI controllers" section of the Device Manager, I only see a SATA Controller (but that's probably normal since these drives are not cabled directly to the motherboard - and aren't supposed to be). The individual manufacturers do not have firmware or model/S-N specific drivers for any of the devices.

I changed the USB interface from High Speed (480mbs) to Full Speed (12mbs) in BIOS - no change. I updated BIOS with "Intel-suggested micro code" updates - no change. These devices are not visible in Disk Management and each shows up as an "Unknown Device" in the Device Manager. All of these devices are readable on an XP machine.

I have tried 4 different drives (two are internal 2.5" laptop drives which I hooked up via a Pro IDE/SATA/USB adaptor) all using USB - Seagate, Seagate/Maxtor, Fujitsu and Hitachi. My machine won't recognize IDE ATA/100 (these are a combination of Ultra, ATA and PATA) external drives either.
