EXCALIBUR

DISK PACK INSPECTION & CLEANING SERVICE

Data recovery by Excalibur Data Recovery, New England's data recovery specailists. Excalibur provides on-site magnetic media maintenance and support on removable disk packs utilized on older mini-computer and mainframe systems. Excalibur's technicians have been servicing all types of removable disk packs from 16MB single disk cartridges up to 300MB disk packs since the early 1970s. Our employees have literally serviced over 1,000,000 disk packs at more than 50,000 customer sites in that time.

Each of Excalibur's employees have worked at one time or another for either Scopus Corporation, Randomex or Precision Methods, the leading disc maintenance firms in the industry. The marketplace transition to PCs and networks forced all three companies to discontinue operations, but their former employees continue to provide this valuable service as Excalibur.

Head crashes, data checks, bad blocks, job aborts and lost data are caused by one of three major problems that develop with removable disc packs which are not routinely maintained ... contamination, disc drive malfunctions and operating mishandling. These problems are inherent whenever packs are subjected to:

Poor Computer Room Environment Dirty Read/Write Heads

Inadequate Storage Environment Numerous Pack Dismounts

Moving a Computer System Contaminated Absolute Filters

Natural Disasters Uninspected Used Disk Packs

Each of these problem areas is addressed and corrected with Excalibur's System 90 Disk Pack Inspection & Cleaning Service.

INSPECTION

A complete physical analysis of each disc pack includes:

Axial & Radial Runout Measurement of each platter (warpage factor of platter).
Inspection of Cover Set for wear or cracks.
Inspection of Spindle Lock for crossed threads or burrs.
Analysis of each platter for head crashes, load marks, and voids in the oxide.

CLEANING

Excalibur's proprietary cleaning system is the product of over 20 years of in-depth experience in servicing over ONE MILLION disc packs. This fully automated system, utilizing thermally bonded man-made cleaning pads, captures and removes the error causing contaminants and film build up from the recording surfaces below the flying height of the drives heads.
