I tested Seagate's Recovery Suite alongside four other recovery utilities using two Macs: an early-2015 MacBook Pro and a late-2014 Mac Mini. Both systems run the same version of macOS Sierra. ![]() The MacBook Pro features a 120GB solid-state drive (SSD), whereas the Mac Mini uses a 500GB hard disk drive (HDD). To ensure uniform testing, I deleted the same files on both machines two weeks prior to testing. (Opens in a new window) Read Our Stellar Phoenix Mac Data Recovery (for Mac) Review In the interest of testing real world usage, I selected six common file types ( DOC, XLS, PDF, JPG, MP3, and MP4). I opted to test both an SSD and HDD because of the challenges solid-state drives present for data recovery software (check out our SSD vs. HDD feature for the differences between the two storage mediums). The issue is a command called TRIM (Opens in a new window), which zeroes out the parts of the drive where deleted files are stored. By clearing sectors that are no longer in use, TRIM extends the lifespan of a SSD, but it also greatly reduces the efficacy of data recovery utilities. There is, however, a possibility that utilities can retrieve recently deleted files. The Recovery Suite must connect with Seagate servers to authorize the software, which made installation the most complicated part of using the software: I spent several days waiting for my software to successfully connect to the STX Server before I could proceed with testing. ![]() The silver lining was that I got to test Seagate's technical support agents, who proved themselves both knowledgeable and prompt. There are two driver modules for the SPI interface(s).Once installed, Seagate exhibits three central features: you can test a drive (Test a Device), scan a volume or device for lost files (Recover Lost Files), or securely erase a folder or volume (Erase Data). ![]() It is in the Raspberry Pi kernel tree but not part of standard Linux (it hasn't been "upstreamed"). The DAC+ DSP Combines the DAC+ technology with a powerful Digital Signal Processor and digital inputs and outputs for applications like filtering, room equalisation or usage as a DAC for external devices Learn more Order HiFiBerry for Business Sound up your Raspberry Pi Create amazing sound on an awesome platform. Every streaming option available for Raspberry Pi has a different set of steps to follow. There has been an effort to write new drivers, following best practises (e.g. Although the following requirements are generalized, they apply in some way to each software option currently available. Plug the Raspberry Pi into its power supply. making more use of Device Tree), and spi_bcm2835 is one of the results. It has been accepted into Linux - it is an upstream driver. We've been trying to make more use of upstream drivers, but this isn't a change that should be made overnight, so the spi-bcm2835 overlay was created to allow people to try out the new driver on a voluntary basis. Browse DigiKeys inventory of Zero Spy Camera for Raspberry Pi Zero BoardEvaluation Boards - Expansion Boards, Daughter Cards. With the switch to the 4.4 kernel we made spi_bcm2835 the default driver, so the overlay is no longer necessary. At this point we know that the device has been detected, is a C-Media type and is considered card 1 by the audio sub-system. Turn a RaspberryPi into an audio spying device. On the whole the switchover has gone smoothly, but some users are reporting problems with some devices that used to work in the 4.1 kernel, so as a short-term measure we may end up writing an spi-bcm2708 overlay to switch back, but at the moment the old driver has been removed from the tree. The USB sound device can be made the default audio device by editing a system file nf : sudo nano /usr/share/alsa/nf. Masumi Zapater over at NIGEKA has done an interesting tutorial on turning the Raspberry Pi into an audio bug Using a USB microphone and standard Linux audio tools, he has worked out how to record and stream the audio to a client computer.
