USB hard disks, USB hard disk enclosures
Many different USB (or firewire) external hard disks are available. It is hard to decide which is better and which is best to avoid.
There is an IDE or S-ATA hard disk inside the external USB enclosures. To communicate between the hard disk and the host (the computer) a special device is required to "translate" USB commands to standard ATA commands. The hard disk can execute such commands (for example, reading, writing and so) and then sends data and results back to the host, through this device again.
USB-ATA bridge chips
This device is called "USB-ATA bridge chip" - the bridge between the host (computer) and the hard disk. Usually this is a small (approx. 1 square centimeter) chip inside the external enclosure, next to the hard disk connector.
Many companies make such USB-ATA bridge chips. They have different features: some of them can allow software like Hard Disk Sentinel to detect hard disk temperature, health and full S.M.A.R.T. information. These USB-ATA bridge chips also allow to use special commands for example to set acoustic level and to test the hard disk using hardware self tests and control the hard disk just like if it were an internal disk.
In contrast, many USB-ATA bridge chips do not support such features. Using hard disks with these USB-ATA bridge chips are not too safe because it is not possible to access any S.M.A.R.T. information about the hard disk. If the USB-ATA bridge chip physically has no support for it, Hard Disk Sentinel will not be able to detect any information about hard disks with such USB-ATA bridge chip. These chips are listed as "Not possible" to support in the table below - because of the required function is missing from the chips.
We always look for other USB-ATA bridge chips and their features. For unknown/new USB-ATA bridge chips we try to get information from manufacturers with more or less success. Of course when a manufacturer can provide information, details and/or an engineering sample unit, we can examine and add full support with high priority.
Determine USB-ATA bridge chip type
From version 2.40, Hard Disk Sentinel displays vendor and product code (VID and PID) of the USB-ATA bridge chip on the "Information" page when the external hard disk is selected.
VID and PID codes of USB-ATA bridge chip in a known USB hard disk enclosure
By this information, it is possible to find out the exact type of the USB-ATA bridge chip without opening the external case which may void the warranty of the external hard disk.
Below you may find information about all known USB-ATA bridge chips up to now. The list will increase as reports arrive about unknown USB-ATA bridge chips. If temperature, health information of your external hard disk is not displayed and you can see a VID/PID pair which is not listed, please use Send test report to developer option.

Not possible means that the required function is missing from the chip, that's why no further information can be displayed about the disk controlled by this chip.
(1): this USB-ATA bridge chip has hardware support but because of missing software interface information, Hard Disk Sentinel does not yet support enclosures built with this USB-ATA bridge chip. Requests for the necessary information are on-going.
(2): reports received about both supported and unsupported devices built with this USB-ATA bridge chip. Please send a report if you use such external enclosure.
Notes
Detection is independent from the size, type, model and manufacturer of the hard disk inside the external enclosure. The functionality of the USB-ATA bridge chip determines if Hard Disk Sentinel can access information about the hard disk.
It is possible that an unknown USB-ATA bridge chip is compatible with any of the existing detection methods. So if the temperature, health and other details of your USB hard disk is diplayed but the VID/PID combination (displayed by the latest version of Hard Disk Sentinel) is not listed in the table, please use Send test report to developer option. This way new compatible USB-ATA bridge chips can be added to the list.
In most cases before purchasing an external hard disk, it is hard to know the type of the USB-ATA bridge chip inside the case. Please check compatibility with external hard disks and hard disk enclosures for the list of known external hard disks/enclosures using compatible USB-ATA bridge chips.
Tehcnically, pendrives and card readers work like external hard disks so you can see vendor and product information (VID/PID) of such devices also.
