APC and its read­ers can be one gi­ant helpdesk. If you have a tech­ni­cal prob­lem, chances are one of us can solve it.

I’m try­ing to use Mail in Win­dows 10 and can­not make the server al­ter­ations re­quired to send mail through an­other ac­count. Where can I find them, please? Colin Travis Sadly, it isn’t pos­si­ble to con­fig­ure an email ac­count in Mail to send mes­sages through a dif­fer­ent mail server, so in­stead, we pointed Colin to­wards eM Client, which is avail­able at www.em­client.com. To do this, go through the eM Client setup wizard to con­fig­ure your ac­count and you should find that it will fail the send­ing mail test. At this point, you may be prompted to en­ter your out­go­ing ac­count cre­den­tials, but if not, click the Menu but­ton and choose ‘Tools > Ac­counts’. The next step is se­lect your ac­count and then switch to the SMTP tab to in­put the de­tails of your out­go­ing server. Here, choose ‘Use th­ese cre­den­tials’ be­fore in­putting your new email ac­count’s user­name and pass­word. You’ll now be able to send your emails. Rob Mead-Green


When my iMac crashed to­day, its logs were full of “Failed to com­pos­ite im­age for de­scrip­tor” er­ror mes­sages prior to forc­ing its shut­down. I also saw some re­peated er­rors from the ker­nel about a “disk1s2: I/O er­ror”. I’ve only re­cently up­graded to El Cap­i­tan: does this in­di­cate an in­com­pat­i­bil­ity with it? Mark Sy­der The up­grade process may have brought on your prob­lem, but the more crit­i­cal and wor­ry­ing of those er­ror mes­sages are those re­lat­ing to disk1s2, which is likely to be an ex­ter­nal hard drive. In­put/out­put er­rors like this are nor­mally the re­sult of a se­ri­ous is­sue with a drive, pos­si­bly even com­plete drive fail­ure or a de­fec­tive elec­tri­cal con­nec­tion. En­sure both ends of the drive’s con­nect­ing ca­ble are fully in­serted into its ports, and that the ca­ble is a good one. Check the drive us­ing Disk Util­ity first, and per­form any nec­es­sary re­pairs. If that re­ports a SMART sta­tus er­ror or other hard­ware fail­ure that can’t be fixed, eject the drive and shut it down im­me­di­ately. Sev­eral util­i­ties, such as the ex­cel­lent DriveDx, can pro­vide you with more de­tails about SMART warn­ings, er­rors and other faults, but once your drive has failed, there is lit­tle point in hold­ing a post mortem. If the drive hasn’t died, it might still be re­cov­er­able. When you have a re­place­ment, you might be able to sal­vage the old drive’s contents and copy them over to your new one. Un­for­tu­nately, sud­den drive fail­ures can still be the cause of crashes, al­though OS X is get­ting more re­silient to such hard­ware is­sues. Howard Oak­ley


I have been spring-cleaning by run­ning the Chkdsk tool on my hard drive, and now it’s con­tin­u­ally run­ning it at startup. How do I pre­vent this? Han­nah East­well

Win­dows’ Chkdsk disk util­ity scans hard drives for er­rors.

SMART sta­tus check­ers, such as DriveDx, are use­ful be­fore fail­ure; af­ter, try re­pair­ing in Disk Util­ity.
