PC-3000 UDMA

The PC-3000 UDMA is a hardware-software solution intended for diagnosing and repairing HDD based on SATA (Serial ATA) and ATA (IDE) interfaces for numerous vendors (Seagate, Western Digital, Fujitsu, Samsung, Maxtor, Quantum, IBM (HGST), HITACHI, TOSHIBA), for various capacities (from 500MB to 6 TB) and various form factors: 3.5″ – desktop drives, 2.5″ and 1.8″ – laptop drives, and 1.0″ – portable drives with Compact Flash interfaces.

The PC-3000 UDMA coupled with the Data Extractor UDMA forms the PC-3000 UDMA Professional System that allows you to recover data from SATA, ATA (IDE) HDD. If you wish to repair these HDD, you need only the PC-3000 UDMA, and for data recovery you need the combination of PC-3000 UDMA and Data Extractor UDMA.

 

THE PC-3000 UDMA Hardware

PC-3000 UDMA PC-3000 UDMA

The new PC-3000 UDMA is a three-port tester-board which is inserted into a PCI-Express expansion slot and has 2 SATA ports (data transfer speed up to 133 MB/s) and 1 PATA (speed up to 100 MB/s) port. The primary port is SATA0 while SATA1 is a secondary port which is switchable with the PATA port. The PC-3000 UDMA provides two simultaneous connections for two drives – the first port is used for SATA and the second one can be used either for SATA or for PATA (it depends on your needs). Thus, you can work either with 2 SATA drives or 1 SATA and 1 PATA at the same time.

When developing the new PCI-Express-based PC-3000 UDMA system, we used the main features from the previous generation of PCI-based PC-3000 UDMA, which proved to be the best, most reliable, and most optimally performing data recovery system possible, while at the same time maintaining a reasonable price.

Processing modes:

  • SATA x2 — UDMA133, UDMA100, UDMA66, UDMA33, PIO4, PIO3, PIO2, PIO1, PIO0
  • PATA x1 – UDMA100, UDMA66, UDMA33, PIO4, PIO3, PIO2, PIO1, PIO0

Two ports are separable, but when they are both in use they are dependent. There is a slight reduction in performance on the second channel when the first one is fully loaded (no more than 20% reduction) as the PC-3000 UDMA is based on a single-channel PCI-Express bus. At the same time, this technical solution allows a reduction of the total cost of the board and makes it more attractive for small and mid-sized data recovery companies.

According to the diagram, the reading speed of two channels on the new PC-3000 UDMA is much higher than the reading speed of the previous generation of PC-3000 UDMA on the PCI bus.

 

Power supply adapter

A double-channel power supply adapter is located on the board controller and provides independent +5 V, +12 V voltage supply and protection from overvoltage and current overloading. In case of any contingency the HDD power supply is switched off automatically.

In addition, every channel has a feedback circuit with special management software that controls the supplying voltage values and informs the user about any issue with the feed circuit.

 

Resource Management of the PC-3000 UDMA board

One of the most important new features of the PC-3000 UDMA allows for launching of the PC-3000 utility and Data Extractor tasks as separate OS processes. The “PC-3000 Resource manager” software makes using the new PC-3000 UDMA very easy and effective. The “PC-3000 Resource manager” manages port and related process activity, controls the status of the ports, checks process conditions and kills processes when it is necessary.

Once a process is started it can use more than one port. For instance, two processes can be used for every port or two ports can be used by one process.
