As you can imagine Vocaltutor uses a lot of pc storage space, especially with 10,000 backing tracks. Twice in the last 18 months Vocaltutor has had problems with external hardrives, dying and eating files! Vocaltutor now have two external hard drives running, and the main one is backed up onto the other every Friday. Vocaltutor would strongly advise everyone with a PC to do this. Losing work, including a book you have written that took 6 months, can be stressful and heartbreaking. Well thanks to Mach4 Computers Ltd , the last time our external hardrive decided to have a fit, the brilliant David Stelmach stepped in. He was able to recover 70% of the files, which I am hugely grateful for, and has recently (in the last two weeks) been able to restore the Health Singing Book I have been writing, so I am able to continue working on it. David's fees are incredibly low, compared to places like PC World, who can't always help anyway. I was told, ‘just send it back to the manufacturer' which at the time would have taken months and been no good to me. So if you need advice on storage or need help with your PC, Mach4 can definitely help

“Thank you Mach4 for responding so quickly! I didn't expect you to come out on a Sunday! You backed up my data so that I would not lose my valuable university work, photos and music, then removed the nasty virus that had blocked my access to everything, and, incidentally, was not detected or removed by my internet provider's supplied ‘malware protection' software. Then, after restoring my operating system, you set up an effective anti-virus programme, restored my broadband connection and reinstalled my files. My computer now runs faster than it ever did! Thank you!!"
