Hard drive rebuild, in the gen­eral sense of the term, can mean a sim­ple oper­a­tion of replac­ing the firmware (con­troller card) and repro­gram­ming it using spe­cial­ist soft­ware. Or it can mean replac­ing the drive’s pre­ci­sion com­po­nents like its read/​write head, done in Class 100 clean rooms by spe­cial­ist data recov­ery technicians.

Hard Dri­ves Are Sus­cep­ti­ble to Failure

Hard dri­ves are electro-​​mechanical devices that are spin­ning even when the com­puter is idle. Typ­i­cal spin rates vary from 4000 to 15000 rota­tions per minute. They are thus sus­cep­ti­ble to fail­ure as are CD, DVD or tape.

A hard drive rebuild can become nec­es­sary owing to mechan­i­cal fail­ure of the disk but a log­i­cal recov­ery of the file sys­tem may still be needed to make the data read­able. The log­i­cal file sys­tem can get cor­rupted with errors dur­ing the fail­ure of the drive.

Fail­ures can occur through a vari­ety of causes:- power surges, caus­ing phys­i­cal dam­age like a drive head crash, a nat­ural dis­as­ter like fire or flood, drop­ping a lap­top or exter­nal drive, or dam­age caused by faulty design of the drive or its firmware pro­gram­ming, even a virus attack or mali­cious intent could be an issue.

Hard Drive Recovery

Data recov­ery from a hard drive can be sim­ple or complex.

For exam­ple, if the data was lost owing to acci­den­tal dele­tion of files, you might be able to recover them your­self by run­ning a data recov­ery software.

On the other hand, if the read/​write head has crashed and the drive is click­ing or the motor has seized, you will have to entrust your drive to a spe­cial­ist pro­fes­sion­als. They will have a dust free clean room where they will open the drive and replace the dam­aged heads, and the nec­es­sary resources and expe­ri­ence with a range of drive prob­lems to help you in your hour of need.

Data recov­ery pro­fes­sion­als typ­i­cally start by copy­ing the exist­ing image on the dam­aged disk to a backup loca­tion. They will work on a copy try­ing to recover the data using spe­cial­ized tools. Only after they have suc­ceeded are they likely to trans­fer the recov­ered data to a replace­ment drive or give you secure access to their servers so you can check the data is intact and down­load it directly.

Sim­ply replac­ing a dam­aged part like the printed cir­cuit board of the drive can­not put things right; it will require some repro­gram­ming to ensure it is cor­rectly matched.

Does Your Recov­ery Com­pany Have Hard Drive Rebuild Experience?

Hard dri­ves have come a long way since a 5MB RAMAC, weigh­ing a ton, was intro­duced in 1956 by IBM. Today’s dri­ves can be a tiny box in com­par­i­son offer­ing many Ter­abytes (each ter­abyte is a 1000 GB and each GB is a thou­sand MB).

Today, there are many stor­age drive mak­ers each offer­ing mod­els with dif­fer­ent fea­tures. The drive can be a sin­gle drive or a RAID sys­tem with mul­ti­ple phys­i­cal dri­ves with their own cut down oper­at­ing sys­tems and hot swap features.

The drive inter­faces to the com­puter can dif­fer. For exam­ple, it can be IDE, EIDE, SATA, SCSI, Lan, etc.

Data losses can be caused by many dif­fer­ent fac­tors, requir­ing dif­fer­ent kinds of approaches to any recovery.

Only an expe­ri­enced hard drive repairer can iden­tify just the right rem­edy that is both effec­tive and economical

Once you have decided on a hard drive rebuild, check that the com­pany you select is expe­ri­enced and has the resources in house, or is a reseller of a rep­utable estab­lished com­pany who ensures any recov­ered data is man­aged securely for your pro­tec­tion and does not broad­cast your company’s loss of infor­ma­tion on their web­site with­out your permission.

Con­clu­sion

A hard drive rebuild becomes nec­es­sary when you are unable to boot with the drive or to read the data you have stored on it. You will also be bet­ter off if you approach a data recov­ery spe­cial­ist if your drive is mak­ing strange noises (that you have not heard before) or data seems to be dis­ap­pear­ing, or your sys­tem is spew­ing error messages.

Con­sid­er­ing the numer­ous makes and mod­els of hard dri­ves in the mar­ket, each with dif­fer­ing fea­tures, you should approach only an expe­ri­enced data recov­ery com­pany with a track record of suc­cess but beware of the vary­ing costs and just like any pur­chase expen­sive does not mean it is the best.
