USB device on a eSATA port

A nice and mostly undiscovered feature which most of the newer Laptops and Desktops offer, is that you can connect an USB device to your eSATA port.

eSATA/USB is a type of serial port in which eSATAp (Power over eSATA), eSATA or a USB device can be plugged into the same port.

SERIAL ATA INTERNATIONAL ORGANIZATION acknowledges eSATAp as the actual name for the new eSATA/USB combo port. This is to differentiate and to prevent confusion with the original eSATA port.

Only one type of device can be plugged in at any one time.

Can both USB 3 and FW800 used at the same time with two computers?


The fast answer is no. This miniStack is not a network-attached storage (NAS) device.
However some of the newer Wi-Fi routers that also offer excellent network storage (NAS) features when coupled with an external hard drive.
Additionally depending on your operating system, you can have a local area network (LAN) with your main computer (hub), with the miniStack attached to it, and have the second computer access the HDD through an older (non-NAS) router. The second computer access would slower than the HUB.

CAN I USE MY HARD DISC WITH USB CONNECTION


Yes, you can. You'll need a little more hardware however. You can find "hard drive enclosures" at many computer stores, ebay and electronics stores. They look like these. In order to make this work, you need to determine the physical size and interface of the Samsung hard drive first. Most notebook drives are 2.5" and most desktop drives are 3.5" types (regardless of capacity). You'll need to find an enclosure for the drive size and interface type.

The Samsung drive is likely to be either and IDE type with a SATA (serial) or PATA (parallel) interface. Pictures of SATA cables are here, and PATA cables are here. You would select the enclosure depending on 2.5" or 3.5" size and SATA or PATA interface type. Lastly, would be to choose either a USB connection between the computer and enclosure, or an ESATA type. ESATA simply means External SATA. If your computer offers an ESATA jack on the front or rear panel, you might consider using it as it is much faster than USB. If you do not have an ESATA jack, stick with the USB type. All but the most oldest computers support USB 2.0 standard speeds, newer computers have a faster USB 3.0 speed (5Gbit/S) standard, but this hardware is fully backward compatible to the USB 2.0 & USB 1 speed (480Mbi/S) and hardware standards. If your computer has the original USB 1.x standrad speeds, you might consider purchasing a USB 2.0 or 3.0 expansion card as the USB 1.x standard is very slow (just 12 Mbit/S). Check these links for pictures of ESATA, USB 2.0 and USB 3.0 If you look closely, you can see the slight differences. USB 1.0 and USB 2.0 look identical.

Some enclosures will require / include a power adapter for the drive. Make sure you get what is required to get the drive to spin up properly. After your computer is up and running, connect the external drive to the USB jack and let the computer install drivers as needed; then use it as any other thumb drive etc. ESATA however may be different. In any case, follow the instructions included with the enclosure you purchased.

After copying good data, you might be able to format and scan the Samsung drive and map out the errant portions. Even still, I would not use the drive for important information or day to day uses. If you do, be sure to maintain frequent backups.

Good luck!

hi i have got seagate Go 500gb when i connected to my computer it say that insert a disk into your Usb .i would like to know how can i fix it


Can you give any more information? What kind of PC? Age of PC? How old is the external drive? is the drive new? Esata is different then USB. Make sure you are connecting to an eSATA port on the computer. Newer laptops usually have a shared eSATA and USB port.

Device driver problem in Windows XP using a USB 2.0 device on a laptop with USB 1.1 controllers


Disable the USB 1.1 on-board option from the motherboard and install a 2 or 4 port USB 2.0 PCI/ISA card.

These cards are quite cheap these days and will do the trick rather than replacing the more expensive back up external hard drive ESATA/USB 2.0 hard drive.
