1. A variable phase oscillator comprising:
an oscillator having a substantially fixed frequency output signal;

means for periodically generating coded phase values of said oscillator output signal, said generating means including means for quantizing the phase value of said oscillator output signal into a predetermined number of phase steps;

a source of a prescribed phase value; and

means for comparing said periodically generated coded phase values and said prescribed phase value to periodically generate output pulse signals.

2. The invention as defined in claim 1 wherein the relative phase of said output pulse signals in relationship to said oscillator output signal is dependent on said prescribed phase value.

3. The invention as defined in claim 2 wherein said source…

1. A method for recovering data from a flash data storage system, the method comprising the steps of: loading flash data storage media into a device using a flash data storage system, said device being connected to a technical workstation; loading all physical sectors of the flash data media into memory of the technical workstation or remotely controlling the flash data storage system through hardware/software; whereupon data storage on the flash data storage media can be diagnosed and rectified through operation of the data recovery computer portion of the technical workstation.

2. The method as defined in claim 1, further including the step of querying a flash data storage system for information through operation of a data recovery program by…

Magnetic disc drives for recording digital data are well known to the art. In such drives it is desirable to achieve the highest recording density possible, such recording density being a function of both the number of annular tracks per radial inch of disc surface and the number of bits per inch along each track. The optimum number of tracks on the individual discs is dependent on the precision of the head positioning system and on the precision in the alignment of the various read/write heads in the disc drive. The system of the present invention provides for the precise alignment of each of the read/write heads in the disc drive so that an optimum number of tracks per radial…

1. In a disc drive which includes a plurality of read/write magnetic heads and a servo magnetic head mounted for simultaneous movement by an actuator in response to a servo signal from the servo head, and in which the positions of the read/write heads are individually adjustable with respect to the servo head, a system for indicating any misalignment of the individual read/write heads as the particular head produces a cyclic position signal in response to position signals pre-recorded on alignment tracks of an alignment disc, each cycle of said cyclic position signal having a first segment with positive and negative peak amplitudes and a second segment with positive and negative peak amplitudes, the positive and negative peak amplitudes of…

Problem: Copied all data from source PC to the Passport, then deleted the data from the source PC. When the Passport was next connected to the source PC it synced and deleted the data from Passport as well.

A lot of deleted data from the Passport have been recovered; however, the data in terms of file names and reported size but they are all .DML files. They cannot be opened by conventional methods or by changing the file ext. Is this a proprietary WD encryption format?

Solution: First things first: If you thought you had a secure backup of your data on a WD Passport and you plugged it into a computer that crashed/fried/etc. and planned to copy your…

If you have problems with a hard disk which contains important (valuable) data:

* any kind of manipulation with the hard disk or with software could hinder data retrieval or could cause an enormous increase of the retrieval costs.

* do not use any software, even if some guys (internet) told you to do so

* do not run chkdsk or defragmentation, even if you are told to do so

* do not open a hard disk if you don’t have the knowledge, training and the tools (even then you may expect to lose the data)

* contact a (local) DR company; supply them with complete information

* perhaps some data recovery forum could guide you to find the right…
