How to Repair Disk and File System Problems on Your Mac

Modern versions of Mac OS X no longer need you to repair disk permissions. However, that’s not the only issue that can occur with a disk or file system. Mac OS X contains a variety of tools for repairing disk, partition, and file system errors.

These options work like chkdsk on Windows, checking for disk and file system errors and repairing them. You can perform a check from within Mac OS X, but it may sometimes be necessary to use recovery mode to fix problems. In a worst-case scenario, you may have to manually run fsck commands from a terminal in single-user mode.

How to check your Hard Drive or SSD’s Health with S.M.A.R.T.

You can check your SSD health (or hard drive health) with S.M.A.R.T. These attributes can show you critical information about the health of your mechanical and solid-state drives. Regularly checking the attributes will help you prevent data loss due to drive failure. Hard drives and SSDs use S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) to gauge their own reliability and determine if they’re failing. You can view your hard drive’s S.M.A.R.T. data and see if it has started to develop problems.

Review: AMD Radeon RX 7900 XT

The new RDNA3 graphics architecture releases today, and leading from the top are the new Radeon RX 7900 XT (in this review), and the RX 7900 XTX flagship, which we’ve also reviewed today. Both these graphics cards are designed to take the fight to NVIDIA’s high-end: the GeForce RTX 40-series “Ada,” but at highly competitive prices. The RX 7900 XT from this review targets a slightly lower price-point than the RX 7900 XTX flagship, while being designed for the exact same class of gaming—4K Ultra HD maxed out with ray tracing.

The “Navi 31” silicon on which the RX 7900 series is based, features six of these, and hence has a 384-bit wide memory interface. Five of these are enabled on the RX 7900 XT, hence it ends up with a 320-bit memory interface. Each MCD has a 16 MB piece of the GPU’s 96 MB Infinity Cache, the RX 7900 XT gets 80 MB of it.

Review: MSI GeForce RTX 4090 Gaming X

NVIDIA GeForce RTX 4090 is the green team’s flagship card based on the Ada GPU architecture. The card was released in October 2022 and has established itself as “the best, at a price.” During our original launch day coverage I reviewed eight (!) GeForce RTX 4090 cards, today we’re checking out the ninth one. Last year I’ve tested the MSI RTX 4090 Suprim X and the RTX 4090 Suprim X Liquid.

Review: Intel® Core™ i7-13700K Processor

The Core i7-13700K “Raptor Lake” is one of the three processor models that Intel launched on 12 2022. The 13th Gen Core “Raptor Lake” desktop processor family gains significance as it’s the last processor lineup from Intel to use a monolithic silicon, as the company plans to pivot to chiplets with its IDM 2.0 manufacturing strategy, with Meteor Lake and beyond. Raptor Lake also doubles down on the company’s Hybrid architecture, which let it win big against AMD’s rampaging “Zen 3.”
