Cannot detect hard disk

by kreak17 / March 27, 2007 2:14 AM PDT

Hi all,

I recently bought a 250gb wd hard disk with SATA2 support and a nexstar 3(nst-360su) external 3.5" hdd enclosure with SATA to eSATA adapter bracket.

I follow the instructions as stated in the manual, connecting the nexstar thru eSATA to my pc's SATA when on the nexstar, nothing happen. No harddisk detected.

I hooked the hard disk directly to my pc's SATA, and my pc can detect it,I thought maybe cannot detect due to need to format the hard disk, so i formatted it to NTFS file system. After that i retry to conect to nexstar, still cannot.

Try with USB, but sometime can detect sometime cannot.
When it got detected thru USB, only for a few minutes then "offline".
I try using other different USB port also cannot be deteced.
Try with other PC, can be deteced thru USB.

I suspect is either the USB port problem or the power supply for the nexstar3?

Can someone tell me how to solve this problem?

Looks defective.

Since eSATA is SATA and the drive worked internally the defect is likely in the cables or case.

Return those items.

Does the interface to the drive support SATA 2?
by Ray Harinec / March 27, 2007 5:23 AM PDT

If not WD drives need to have a jumper put on. Go tho the WD site and check your model number. Or the diagram and info is on the drive nameplate.

hi all,

i found out from the website (http://www.westerndigital.com/en/products/resources/DriveCompatibilityguide.asp#external) this information...


SATA is very effective for external storage applications, and the external SATA (eSATA) cable and connector application provides a physically secure and fast connection for external hard drives. With up to 3 Gb/s data transfers, this interface is suitable for hard drives, home networking, digital video, and home entertainment devices such as set-top boxes and personal video recorders. eSATA and internal SATA cables and connectors cannot be used interchangeably. This is an important feature since eSATA cables and connectors are designed for 5000 insertion and removal cycles while internal SATA cables and connectors are designed for only 50 insertion and removal cycles. To achieve eSATA connectivity with an external SATA drive, a SATA PCI card must be installed on the host computer."

Can this be the main problem?

BIOS settings for SATA ports
by linkit / March 28, 2007 2:30 AM PDT

What computer model are you using?

What operating system are you using? Any service packs installed? Is it fully updated? Did you ever install the SATA driver?

Some motherboards require you to boot to BIOS and enable the SATA ports. This usually means setting SATA HD detection to "autodetect" or "automatic." Check the motherboard manual.

Some settings will enable only one or two ports. Other settings will enable all SATA ports.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
